Item Validity and reliability of the Turkish Version of DSM-5 Level 2 Somatic Symptom Scale (Child Form for 11-17 years and Parent Form for 6-17 years)Yalin Sapmaz, S; Serim Demirgören, B; Yörük Ülker, G; Aydemir, ÖObjective: This study aimed to assess the validity and reliability of the Turkish Version of DSM-5 (Diagnostic and Statistical Manual of Mental Disorders) Level 2 Somatic Symptom Scale's Child and Parent Forms. Methods: The study group consisted of a community and clinical sample. The scale was applied to 120 parents and 186 adolescents that represented the clinical and community sample. During the assessment process, Child Somatization Inventory was also used. Results: Reliability analyses indicated a high internal consistency regarding DSM-5 Level 2 Somatic Symptom Scales, for parent forms and acceptable internal consistency for child forms. In the meantime, it was shown that both child and parents form for DSM-5 Level 2 Somatization Symptom Scale were significantly correlated with Child Somatization Inventory. As for the content validity, five factors for child forms and three factors for parent forms were obtained and was observed to be consistent with the original construct of the scale. Conclusion: It was concluded that Turkish version of DSM-V Level 2 Somatic Symptom Scale was a valid and reliable tool to be utilized both for clinical practice and research purposes.Item Developing a quality of life instrument in patients with psoriasisInanir, I; Aydemir, Ö; Gündüz, K; Danaci, AE; Türel, ABackground and design Psoriasis is a chronic skin disease which causes psychological, social and physical problems and affects quality of life. The aim of this study was to develop a quality of life instrument for patients with psoriasis which is suitable for Islamic populations. Materials and methods The psychosocial and daily life problems defined by 75 patients with psoriasis, their relatives and physicians were used to construct a questionnaire, the reliability and validity of which were determined in a group of 156 patients with psoriasis. Results For reliability, Chronbach's alpha coefficient was 0.87, and item-total correlations were between 0.37 and 0.60 for internal consistency. There was high test-retest reliability (r = 0.98, P < 0.001). For validity, three factors were extracted in the principal components method for construct validity. The maximum factor loadings of each item were between 0.456 and 0.681. For convergent validity, all patients' self-ratings and Psoriasis Area and Severity Index (PASI) were correlated with the questionnaire score (P < 0.001). Conclusions The questionnaire consisting of 17 items was found to be suitable for both epidemiologic and clinical trials.Item Reliability and validity of Turkish Version of DSM-5 Psychosis ScaleHerdem, A; Dikici, DS; Aydemir, ÖObjective: In this study we evaluated the reliability and validity of the Turkish version of DSM-5 Psychosis Scale developed in order to evaluate severity of psychosis in adult patients. Methods: This study was carried out with patients who met the diagnostic criteria for any psychotic disorder according to DSM-5 criteria and who are undergoing treatment in the inpatient and outpatient wards of Psychiatry Department of Celal Bayar University Medical School. Except for psychotic disorders patients with any mental or physical disease were excluded. A total of 49 patients (40 patients with schizophrenia, six patients with not otherwise specified psychotic disorder, three patients with schizoaffective disorder) were included in the study. One hundred and one volunteers without any mental or physical disease were included as the healthy control group. Reliability analysis was based on internal consistency and item-total score correlation. Validity analysis was based on exploratory factor analysis, comparison of mean scores of the patient and healthy control groups and ROC analysis. Results: The mean age of the study group was 26.0 +/- 10.3 years and 52.7% of the sample group (n = 79) were female. Sixty-nine point three percent of the study group were college graduates, 8% primary school graduates, 19.3% is also high school graduates. Mean disease duration was 17.1 +/- 9.7 years in the psychotic disorder group. The internal consistency of the Psychosis Scale was 0.91 and, item-total correlation coefficients of the Psychosis Scale were between 0.25 and 0.82. In the factor analysis, for sample adequacy Kaiser- Meier-Olkin (KMO) coefficient was found as 0.81 and Bartlett coefficient as 1.03. Single-factor solution was obtained and the eigenvalue is 5.12, representing 64.0% of the total variance. Factor loadings of the items of the scale were between 0.33 and 0.88. The mean of score was 11.00 +/- 5.20 in patient group while it was calculated as 0.21 +/- 1.21 in control group. The area under the curve was calculated as 0.98 in the ROC analysis. Conclusion: These results indicate that the Turkish version of Psychosis Scale is reliable and valid.Item The impact of self-stigmatization on functioning in bipolar disorderAydemir, ÖObjective: It has been shown that self-stigmatization causes low self-esteem and social anxiety in bipolar patients. In this study it is aimed to demonstrate the impact of self-stigmatization on psychosocial functioning in bipolar disorder. Method: The study was carried out with 70 patients diagnosed with bipolar disorder. All patients were in remission and the remission state was confirmed by a 17-item Hamilton Depression Rating Scale score less than 7 and a Young Mania Rating Scale score less than 5. For the assessment of self-stigmatization, sense of stigmatization subscale of Bipolar Disorder Functioning Questionnaire (BDFQ-Stigma) was used. In the assessment of functioning, Functioning Assessment Short Test (FAST) was applied which includes the dimensions such as autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relations, and leisure time. In the statistical analysis, regression analysis was performed. Results: In the regression analysis, R square was found to be 0.205 and the model was statistically significant (F=3.225, p=0.007). The only domain which is affected by self-stigmatization was found to be interpersonal relations (Beta=0.888, t=2.000, p<0.05). Conclusion: It is concluded that self-stigmatization has negative impact on interpersonal relations by causing social anxiety as demonstrated previously. On the other hand self stigmatization does not show any adverse effect on the other dimensions of FAST including occupational functionality.Item Adaptation of the Dementia Attitudes Scale into TurkishÇetinkaya, A; Elbi, H; Altan, S; Rahman, S; Aydemir, ÖIntroduction: The aim of this study was to assess psychometric properties of the Turkish version of the Dementia Attitudes Scale which is developed to determine attitudes towards dementia. Methods: 326 volunteered students between the age of 20-44 years, studying in Manisa Celal Bayar University Faculty of Medicine and Faculty of Health Sciences are included in this methodological study. Data of the study were collected with Demographic Data Form, Dementia Attitudes Scale and UCLA-Geriatrics Attitudes Scale. For the analysis of the data, the SPSS and Lisrel software were used. Results: The Cronbach's alpha coefficient of the Dementia Attitudes Scale is 0.84 which is quite high. Confirmatory factor analysis has supported three factor-structure of the scale: Supporting attitude, Accepting attitude and Exclusionary attitude. Confirmatory factor analysis revealed goodness of fit coefficients as 0.076 for RMSEA, 2.86 for the chi-square/sd, and 0.93 for CFI. The analysis showed that the adapted scale fits the model very well. The scale can discriminate between demographic characteristics and attitudes to dementia. The scale significantly correlates with UCLA-Geriatric Attitudes Scale measuring attitude towards the elderly. Conclusion: Dementia Attitude Scale is a valid and reliable scale that can be used in studies evaluating the attitude towards dementia.Item Quality of life in asthma (SF-36 questionnaire)Yorgancioglu, A; Aydemir, Ö; Çelik, P; Topçu, FThis study is aimed to evaluate the quality of life (QoL)in 52 asthmatics using the SF-36 health status questionnaire which is based on 36 items to represent 8 health domains. These domains were evaluated according to age, gender, status of education, duration and severity of asthma, day and night symptoms, FEV1 and PEF values, emergency admissions, usage of steroids The emotional and physical role difficulties, and social and physical functions were worse in the group of poorly educated. General health perception was strongly and inversely correlated with the duration of asthma, the patients with PEFR values over 80% were significantly better in the physical role difficulties Physical and social functions were worse in patients having day symptoms. As the severity of airway obstruction increases, the emotional role difficulties become more significant. Emotional and functional role difficulties were also more frequent in patients on steroid therapy. As asthma may impair the daily life so severely, QoL questionnaires should always be used in the management of asthma.Item Adaptation and Reliability of the Structured Clinical Interview for DSM-5-Disorders - Clinician Version (SCID-5/CV) to the Turkish an LanguageElbir, M; Alp Topbas, Ö; Bayad, S; Kocabas, T; Zulkif Topak, O; Çetin, S; ÖzdeL, O; Atesçi, F; Aydemir, ÖObjective: In this study, we aimed to adapt the Structured Clinical Interview for DSM-5-ClinicianVersion into Turkish and to demonstrate its reliability. Method: A total of 185 patients, both inpatient and outpatient, from two different university hospitals were included. Training sessions on the features and use of SCID-5/CV were held before the data collection. During the study, in order to test the diagnostic agreement and accuracy, two psychiatrists remained present at the evaluation of each participant; alternatively being interviewer and the observer. Cohen's kappa coefficient for inter-rater reliability was calculated for every diagnostic category. Results: The patient group had a mean age of 37.2 (+/- 13.5) years and 55.7% were female. The education status was as follows: 2.7% were illiterate, 1.7% literate with no primary education, 33% had primary education, 23.8% had secondary education and 38.9% had higher education. The calculated kappa value showed excellent agreement for schizophrenia (kappa=0.93), bipolar disorder (kappa=0.96), major depressive disorder (kappa=0.89), dysthymic disorder (kappa=0.82), alcohol use disorder (kappa=0.96), panic disorder (kappa=0.84), agoraphobia (kappa=0.85), social anxiety disorder (kappa=0.95), generalized anxiety disorder (kappa=0.89), obsessive compulsive disorder (kappa=0.87), posttraumatic stress disorder (kappa=0.89), adult attention deficit and hyperactivity disorder (kappa=1.00), specific phobias (kappa=0.82) and very good agreement with adjustment disorder (kappa=0.78) and somatic symptom disorder (kappa=0.65). Conclusion: Similar to the past SCID versions, kappa values were found to be quite high and all were statistically significant. The Turkish version of SCID-5/CV can be reliably used in both clinical practice and clinical studies.Item Reliability and validity of Turkish Form of DSM-5 Mania ScaleÖztekin, S; Alçi, D; Aydemir, ÖObjective: This study aimed to demonstrate the reliability and validity of the Turkish form of DSM-5 Mania Scale which was developed according to DSM-5 criteria to measure the severity of mania. Methods: This study was conducted with 50 patients who meet the diagnostic criteria of bipolar disorders according to DSM-5 criteria who are within manic or euthymic episode. The patients were under treatment at inpatient and outpatient clinics of Psychiatry Department of Celal Bayar University, Medicine Faculty. Patients with any mental or physical disease except bipolar disorders were excluded. Sixty-three volunteers without any mental or physical disease were included as healthy control group. Beside DSM-5 Mania Scale the most widely used scale Young Mania Rating Scale (YMRS) was used for concurrent validity. In reliability analyses internal consistency coefficient and item-total correlation analysis; in validity analyses factor analysis and correlation analysis with the Pearson Correlation Analysis were performed. Results: The mean ages of the bipolar disorders group (n=50) and healthy control group (n=63) were respectively 30.9 +/- 13.6 and 22.4 +/- 5.8. 53.7% of the sample group (n=58) were female. Disease duration of bipolar disorder group was 7.2 +/- 7.9 years. The internal consistency of the DSM-5 Mania Scale was 0.91 and, itemtotal correlation coefficients of the DSM-5 Mania Scale were between 0.67 and 0.85. In the explanatory factor analysis, for sample adequacy Kaiser- Meier-Olkin (KMO) coefficient was calculated as 0.85 and Bartlett coefficient was 389.51. Single-factor solution was obtained and the eigenvalue was 3.69, explaining 73.8% of the total variance. Factor loadings of the items were between 0.77-0.91. Significant and high levels of correlation were determined between YMRS and DSM-5 Mania Scale (r=0.78). Conclusion: These findings have been shown that the DSM-5 Mania Scale is reliable and valid for Turkish.Item Reliability and validity of Turkish Form of Agoraphobia ScaleAydin, O; Çöldür, EÖ; Aydemir, ÖThe purpose of the present study was to investigate the validity and reliability of the Turkish Form of the Agoraphobia Scale. The scale was originally developed to measure the severity of agoraphobia regarding the DSM-5 criteria. Methods: This study was conducted at the Department of Psychiatry in Celal Bayar University Hospital. The participants were in-or out-patients diagnosed with any anxiety disorder according to the DSM-5. The exclusion criteria were comorbidity of other psychiatric disorders and/or physical diseases. Accordingly, 50 patients with anxiety disorder were included in the study and these were distributed as panic disorder in 14 patients, generalized anxiety disorder in 10 patients, agoraphobia and obsessive-compulsive disorder in four patients, post-traumatic stress disorder in one patient and not otherwise specified anxiety disorder in 17 patients. One hundred and three volunteers without any mental or physical disease were also included to represent the healthy control. Additionally the most widely used self-rated scale of the Spielberger's State-Trait Anxiety Inventory was used for concurrent validity. Reliability analysis was performed to examine the internal consistency of the Turkish version of the scale. Additionally, item-total correlations were reported. In terms of examining the validity of the scale, subgroup validity analysis was conducted to investigate whether two groups of patients differ in their scores on the scale. ROC analysis was also performed. Results: The mean age of the study group was 29.0 +/- 11.8 and 60.1% of the sample group (n=92) were female. 66.0% of the group were college graduates, 19.0% primary school graduates, 15.0% is also high school graduates. Disease duration of anxiety disorder group was 17.1 +/- 9.7 years. The internal consistency of the Agoraphobia Scale was 0.95 and, item-total score correlation coefficients of the Agoraphobia Scale were between 0.66 and 0.87. In the explanatory factor analysis, for sample adequacy Kaiser-Meier-Olkin (KMO) coefficient was 0.92 and Bartlett coefficient was 1.57. Single-factor solution was obtained and the eigenvalue was 7.16, explaining 71.68% of the total variance. Factor loadings of the items were between 0.71 and 0.90. Coefficient of Spearman correlation analysis was r=0.31. Conclusion: Results demonstrated that the Turkish version of the Agoraphobia Scale was a valid and reliable instrument which may serve as useful in guiding future research that aims to measure agoraphobia severity.Item Relationship of sexuality with psychological and hormonal features in the menopausal periodDanaci, AE; Oruç, S; Adigüzel, H; Yildirim, Y; Aydemir, ÖWomen may experience some mental and sexual problems between the ages of 40 years and 60 years due to serious changes in the hormonal system. The aim of this study was to examine the relationships between the changes in sex hormones, sexual behaviours, depression and anxiety levels of women who were in either the premenopausal, perimenopausal or postmenopausal period The subjects of this cross-sectional study consisted of 324 women who attended the Gynaecology and Obstetrics Out-Patient Ward of Celal Bayar University Hospital. Of this group, 37.0% (n = 124) were postmenopausal, 27.2% (n = 84) perimenopausal and 35.8% (n = 116) premenopausal. Beck Depression Inventory (BDI), State and Trait Anxiety Inventories (STAI-I and II) and a questionnaire on sexual behaviour which was prepared for this study by the authors, were applied to all of the attendees and serum sex hormone levels were analyzed Beck Depression Anxiety, STAI-I and STAI-II scores and sexual behaviours did not show any statistically significant difference among these three groups. The frequency of sexual intercourse was lower in women with high BDI scores. The rate of painful intercourse was higher in women with high STAI-I scores. The frequency of sexual intercourse, sexual desire and orgasm decreased and painful intercourse increased in women with high STAI-Il scores. The frequency of sexual intercourse decreased significantly as the age or follicle stimulating hormone level of women increased These findings have revealed that the menopausal state did not affect the sexual behaviour, and psychological state of women between the ages of 40 and 60 years, but the increase in anxiety and depression scores affected the sexual life in a negative manner.Item Validation of the Turkish Form of Short Form-12 health survey version 2 (SF-12v2)Gündüz, ÖS; Mutlu, S; Basli, AA; Gül, C; Akgül, Ö; Yilmaz, E; Aydemir, ÖObjectives: In this present study, we aimed to perform the reliability and validity analyses of the Turkish Form of Short Form-12 version 2 (SF-12v2) in different groups of patients. Patients and methods: After the permission for the validation study of the Turkish Form, Optum provided the authors the validly translated Turkish Form of SF-12v2. The study was carried out in rheumatological, psychiatric, and surgical wards of Manisa Celal Bayar University Hafsa Sultan Training and Research Center between September 2019 and June 2020. Taking possible dropouts into consideration, a total of 136 patients (67 males, 69 females; mean age: 43.5 +/- 14.4 years; range 19 to 82 years) constituted the study group. In addition to SF-12v2, for concurrent validity, Nottingham Health Profile (NHP) was used as the comparator instrument. Results: In internal consistency, for the physical component summary score, the Cronbach alpha coefficient was 0.80, and item-total score correlation coefficients were between 0.32 and 0.73. The Cronbach alpha coefficient of the mental component summary score was found to be 0.88 where the item-total correlation coefficients varied between 0.60 and 0.78. Exploratory factor analysis revealed a two-factor solution, representing mental and physical components. For criterion validity, convergent and discriminant validity analyses were performed using NHP with SF-12v2, and domains of SF-12v2 correlated well with the domains of NHP accordingly. In criterion validity, the psychiatric group had the lowest mean score in mental health, vitality, social functioning and role difficulties due to emotional problems, whereas the surgical group had the lowest mean score in bodily pain, role difficulties due to physical problems, and physical functioning. Conclusion: Our study results show that the Turkish form of SF-12v2 is valid and reliable both in clinical practice and clinical trials.Item Attention deficit and hyperactivity symptoms in children with monosymptomatic nocturnal enuresisErtan, P; Gönülal, D; Sögüt, A; Yilmaz, Ö; Bozgül, A; Dinç, G; Aydemir, Ö; Yüksel, HAim: Monosymptomatic nocturnal enuresis in children may cause psychological and behavioral problems. The aim of this study was to assess symptoms of attention deficit and hyperactivity in children with monosymptomatic nocturnal enuresis. Material and Method Fifty-seven children (23 male, 34 female) with monosymptomatic nocturnal enuresis and 57 healthy controls (25 male, 32 female) aged 6 to 12 years participated in the study. Conners' Parent Rating Scale-48 (CPRS), a 48-item multiple-choice questionnaire, was completed by the mothers to identify the attention deficit and hyperactivity symptoms in children. Results: Mean age of the children with enuresis was 8.54 +/- 2.18 years and that of the control group 9.12 +/- 2.13 years. Attention deficit score in the enuretic group was significantly higher than that in the control group (p=0.02). Hyperactivity scores were not significantly different between the groups (p=0.36). Bedwetting frequencies were not different between enuretic children with and without attention deficit or hyperactivity symptoms (p=0.06). Conclusions: Psychological and behavioral assessment may be indicated in children with monosymptomatic nocturnal enuresis since the results of this study demonstrate increased attention deficit symptomatology. (Turk Arch Ped 2010; 45: 37-40)Item Serum Brain-Derived Neurotrophic Factor (BDNF) Levels in Schizophrenic Patients with Depressive Sypmptoms: A Preliminary StudyEsen-Danaci, A; Aydemir, Ö; Deveci, A; Taneli, F; Taskin, OObjectives: Evidence from clinical, pharmacological and animal studies, have led to neurodevelopment, neurodegeneration, and dopamine hypotheses, and to the investigation of BDNF as a potential candidate molecule in the pathophysiology of schizophrenia, The aim of this study is to investigate the BNDF levels of schizophrenic patients with depression and compare them with major depression patients and controls in order to understand the nature of depressive symptoms seen in schizophrenia. Methods: The BDNF levels of eight schizophrenic patients with depressive symptomatology (SD) were compared with two control groups. The first group consisted of major depressed patients (MDD) (n=24) and the second was the healthy control group (n=26). Results: SD group had BDNF levels similar to control group and MDD group had significantly lower levels than the other two groups. Conclusion: This difference of BDNF levels between schizophrenia with depression group and major depression group supports the hypothesis of distinct etiologies.Item Depression and anxiety in hyperthyroidismDemet, MM; Özmen, B; Deveci, A; Boyvada, S; Adigüzel, H; Aydemir, ÖBackground. Our objective was to determine symptomatology of depression and anxiety in patients with untreated hyperthyroidism and compare with euthyroid patients. Methods. Thirty-two patients with hyperthyroidism (high free T3 and free T4, and suppressed TSH) and 30 euthyroid (normal free T3, free T4, and TSH) controls attending the Endocrinology Out-Patient Department at Celal Bayar University Hospital in Manisa, Turkey were included in the study. Hormonal screening was performed by immunoassay and hernagglutination method. For psychiatric assessment, Hospital Anxiety and Depression Scale [HAD], Hamilton Depression Rating Scale [HAM-D], and Hamilton Anxiety Rating Scale [HAM-A] were used. There was no difference between the two groups in terms of demographic features. Results. Total scores obtained both from HAM-D and HAM-A were significantly greater in the hyperthyroidism group than that of the euthyroid group (P < 0.05); there was no difference in terms of HAD. When compared in terms of symptomatology, early insomnia (HAM-D#6), work and activities (HAM-D#7), psychic anxiety (HAM-D#10), weight loss (HAM-D#16), insomnia (HAM-A#4), and cardiovascular symptoms (HAM-A#8) were significantly more frequent in the hyperthyroidism group. By Wilks lambda discriminant analysis, psychomotor agitation (HAM-D#9), weight loss (HAM-D#16), and insomnia (HAM-A#4) were found as the discriminating symptoms for the hyperthyroidism group, whereas somatic anxiety (HAM-A#11) and loss of interest (HAD#14) were distinguishing symptoms of the euthyroidism group. Conclusions. Hyperthyroidism and syndromal depression-anxiety have overlapping features that can cause misdiagnosis during acute phase. For differential diagnosis, one should follow-up patients with hyperthyroidism with specific hormonal treatment and evaluate persisting symptoms thereafter. In addition to specific symptoms of hyperthyroidism, psychomotor retardation, guilt, muscle pain, energy loss, and fatigue seem to appear more frequently in patients with comorbid depression and hyperthyroidism; thus, presence of these symptoms should be a warning sign to nonpsychiatric professionals for the need for psychiatric consultation.

Methods: Oxidative stress markers, cognitive functions, and domains of psychosocial functioning were evaluated in 51 patients with bipolar disorder who were in remission. Correlation analyses between these parameters were calculated with data controlled for duration of illness and number of episodes. Results: There was no statistically significant correlation between oxidative stress markers and cognitive functions. In terms of psychosocial functioning, significant correlations were found between malondialdehyde and sense of stigmatization (r = -0.502); household activities and superoxide dismutase (r = 0.501); participation in social activities and nitric oxide (r = 0.414); hobbies and leisure time activities and total glutathione (r = -0.567), superoxide dismutase (r = 0.667), and neurotrophin 4 (r = 0.450); and taking initiative and self-sufficiency and superoxide dismutase (r = 0.597). There was no correlation between other domains of psychosocial functioning and oxidative stress markers. Conclusion: These results imply that oxidative stress markers do not appear to correlate clearly with cognitive impairment and reduced psychosocial functioning. However, there were some associations between selected oxidative markers and activity-oriented functional markers. This may represent a true negative association, or may be an artifact of oxidative stress being a state rather than a trait marker.Item Reliability and validity of Turkish Form of Sleep Disorder ScaleYüzeren, S; Herdem, A; Aydemir, ÖObjective: This study, demonstrate the reliability and validity of the Turkish form of DSM-5 Sleep Disorder Scale which improved according to DSM-5 criteria to measure the intensity of sleep disorder. Methods: This study were carried out with patients fulfilling the diagnosis of any sleep disorder according to DSM-5 criteria and who are undergoing treatment in Celal Bayar University Hospital sleep medicine inpatient or outpatient clinic. Patients with any mental or physical disease except for anxiety disorders were excluded. As a result, 50 patients with sleep disorder were included in the study and diagnoses of OSAS in 41 patients, primer insomnia in five patients, parasomnia in three patients and narcolepsia in one patient were made. Without any mental or physical disease in 50 volunteers formed the control group. Beside the DSM-5 Sleep Disorder Scale, the most widely used scale for sleep disorders, Pittsburgh Sleep Disorder Index (PSQI), was used for validation. Internal consistency coefficient and item-total score correlation analysis for reliability analysis; factor analysis and correlation analysis with the PSQI, and ROC analysis for discrimination between the sleep disorder and healthy control group for validity were performed. Results: The mean age of the study group was 39.3 +/- 15.8 years and 47.0% of the sample group (n=47) were female. 55.0% of the group were college graduates, 22.0% primary school graduates, 18.0% were high school graduates. Disease duration of sleep disorder group was 16.8 +/- 12.6 years. The internal consistency of the DSM-5 Sleep Disorder Scale was 0.91 and, item-total score correlation coefficients of the DSM-5 Sleep Disorder Scale were between 0.61 and 0.81. For the factor analysis, the sample adequacy of DSM-5 Sleep Disorder Scale was determined with Kaiser- Meier-Olkin (KMO) analysis where the coefficient was 0.91 and Bartlett analysis where chisquare was 1.54. Single-factor solution was obtained and the eigenvalue is 5.07 representing 63.4% of the total variance. Factor loadings of the items of the scale were between 0.69-0.87. Coefficient of correlation analysis with PSQI was calculated as r=0.727. In the ROC analysis, the area under the curve was obtained as 0.76. Conclusion: These findings have been shown that the DSM-5 Sleep Disorder Scale is reliable and valid for Turkish.Item Reliability and validity of the Turkish Version of DSM-5 Level 2 Anger ScaleÇöldur, EÖ; Öztekin, S; Aydemir, ÖObjective: The purpose of the present study was to investigate the reliability and validity of the Turkish Form of Level 2 Anger Scale. The scale was originally developed to measure the severity of anger regarding the DSM-5 criteria. Methods: This study was conducted in the Department of Psychiatry in Celal Bayar University Hospital. The participants were in- or out-patients diagnosed with any psychotic disorders according to the DSM-5. The exclusion criteria were comorbidity of other psychiatric disorders and/or physical diseases. The participants were 49 patients who were diagnosed with schizophrenia (n=40), schizoaffective disorder (n=3), and not otherwise specified psychotic disorder (n=6). One hundred and one volunteers without any mental or physical disease were also included to represent the healthy control. In the assesment beside Level 2 Anger Scale, 18-item Brief Psychiatric Rating Scale was used. In reliability analysis internal consistency coefficient and item-total correlation analysis were performed; for validity analysis exploratory factor analysis was performed. In concurrent validity correlation analyses between Level 2 Anger Scale and BPRS tension, hostility, uncooperativeness, and elated mood subscales were computed. In order to discriminate between the psychosis and the control group, group means of Anger Scale were compared with t-test. Results: The mean age of the study group was 26.0 +/- 10.3 and 52.7% of the sample group were female (n=79). 69.3% of them were graduated from university (n=104), 19.3% from high school (n=29), and 8% from elementary school. Disease duration of psychotic disorder group was 17.1 +/- 9.7 years. The internal consistency of the Level 2 Anger Scale was 0.91 and, item-total correlation coefficients were between 0.74-0.83. For the exploratory factor analysis of sample adequacy of Level 2 Anger Scale Kaiser- Meger-Olkin (KMO) coefficients 0.81 and Bartlett coefficient 1.03 was found. Single-factor solution was obtained and the eigenvalue is 3.79, representing 75.80 % of the total variance. Factor loadings of the items of the scale were between 0.83-0.90. The mean of score was 5.09 +/- 0.72 in the psychosis group while it was calculated as 3.65 +/- 0.36 in the control group. There was a statistically significant difference between the groups. There were moderate to high correlations between Level 2 Anger Scale and BPRS tension, hostility, uncooperativeness, and elated mood. Conclusion: Results demonstrated that the Turkish version of Level 2 Anger Scale is a valid and reliable.Item The reliability and validity of the Turkish Version of the Affect Underpinned by Severity and Social Impairment Questionnaire (AUSSI)Çetinay, P; Akbay, S; Bilen, C; Gülseren, S; Aydemir, ÖObjective: The Affect Underpinned by Severity and Social Impairment Questionnaire (AUSSI) allows clinicians to describe mood symptoms and social impairment and to follow up residual symptoms after treatment in patients with major depressive disorder. The aim of this study was to investigate the reliability and validity of the Turkish version of the AUSSI. Method: The study included 137 (117 female and 20 male) patients between 18 and 65 years of age who were diagnosed as major depressive disorder according to DSM IV diagnosis. Also 32 control subjects (25 female and 7 male) were included. All subjects completed a Sociodemographic Information Form and the Turkish version of the Affect Underpinned by Severity and Social Impairment Questionnaire. The patients were also assessed by Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale (HARS) and Brief Disability Questionnaire (BDQ). For reliability Cronbach's coefficient and split-half reliability analyses were performed. For validity analyses, factor analyses were performed. Pearson correlation coefficient between HDRS, HAIRS, BDQ, and AUSSI were also measured. Results: Concerning the reliability of the scale, Cronbach's alpha coefficient was 0.897, Gutman Split-half coefficient was calculated by split half method as 0.862. Cronbach's alpha coefficient composed of 6 items for the first part was 0.801, and for the second part containing the 5 items was 0.857. In order to determine the construct validity of AUSSI, a principal component factor analysis with Varimax rotations was performed, and two factors (Affect Severity, Social Impairment) were obtained with Eigenvolue greater than 1.0. Also correlations of AUSSI total between BDQ (r=0.61, P<0.001), HDRS (r=0.74, p<0.001) and HAIRS (r=0.69 P<0.001) scores were significant. Conclusion: The Turkish version of the Affect Underpinned by Severity and Social Impairment Questionnaire was found to be reliable and valid in this study.Item Adaptation of the Short-form 6-item UCLA Loneliness Scale (ULS-6) into TurkishElbi, H; Çetinkaya, A; Cambaz Ulas, S; Atay, E; Aydemir, ÖObjective: The short-form 6-item UCLA Loneliness Scale is a brief assessment scale developed to determine the level of loneliness from a onedimensional perspective while preserving psychometric properties equivalent to the original 20-item version. This study aimed to adapt the shortform 6-item UCLA Loneliness Scale into Turkish and to analyze its validity and reliability. Method: The convenience sampling method was preferred for this methodological study, in which 411 clinical and non-clinical individuals were included. The clinical group included 41 patients with major depressive disorders attending the psychiatric outpatient ward. The study's data were collected with the Descriptive Information Form, short-form 6-item UCLA Loneliness Scale, Multidimensional Scale of Perceived Social Support, Beck Depression Inventory, and Trait Anxiety (A-Trait) Scale. Results: The Cronbach's alpha value of the UCLA Loneliness Scale-6 Item Short Form was calculated as 0.884, and the scale's internal consistency level was quite high. For the UCLA Loneliness Scale-6 Item Short Form, the variability level of the items constituting the one-dimensional structure produced from the explanatory factor analysis was 63.411%, and it could distinguish patients with descriptive features and clinical diagnosis (p<0.05). The scores of the UCLA Loneliness Scale-6 Item Short Form and other scales assessing loneliness showed a significant correlation (r=0.476- 0.618). Conclusion: The short-form 6-item UCLA Loneliness Scale is a simple, easy-to-apply, reliable, and valid scale that can be used in studies assessing loneliness.Item Reliability and Validity of the Turkish Version of the Burden Assessment ScaleAydemir, Ö; Dikici, DS; Akdeniz, F; Kalayci, FBackground: In this study, it is aimed to evaluate the reliability and validity of the Turkish version of the Burden Assessment Scale. Methods: The study was carried out on 100 volunteers who were caregivers of in-or outpatients at a university hospital, department of psychiatry. The diagnoses of the patients were schizophrenia (25%), bipolar disorder (22%), major depressive disorder (24%), and anxiety disorder (29%). The mean duration of the illness was 8.2 +/- 8.7 years. For the concurrent validity, the Perceived Family Burden Scale and the Zarit Caregiver Burden Scale were used. In the statistical analyses, internal consistency, item-total score correlation, explorative factor analysis, correlation with other scales were calculated. Results: The Turkish version of the Burden Assessment Scale was prepared after the translation and back-translation of the original scale and after the consensus on the translated form. In the internal consistency analysis, Cronbach alpha coefficient was found to be 0,894 and item-total score correlation coefficients were between 0.297 and 0.742. In the explorative factor analysis, a five-factor solution explaining 67.2% of the total variance was obtained and the conceptual themes of the factors were limitations in daily life, negative emotions, worry for the patient, losses of the caregiver, and disruption in activities. The correlation of the Burden Assessment Scale with the Perceived Family Burden Scale was r=0.485 and with the Zarit Caregiver Burden Scale was r=0.610. Conclusion: It is demonstrated that the Turkish version of the Burden Assessment Scale which is convenient in the milder forms of psychiatric disorders and which is developed for the assessment burden of patients on their caregivers is reliable and valid.
