Eighty-one volunteer older adults were included in the study. Test–retest reliability was evaluated using the intraclass correlation coefficient. Correlation coefficients between YPAS-TR and Physical Activity Scale for the Elderly (PASE), Short Form-36, and Short Physical Performance Battery were examined for convergent validity. Acceptable intraclass correlation coefficient values were reached for YPAS-TR energy expenditure, total physical activity time and summary, vigorous, leisurely walking, moving, standing, and sitting indices (intraclass correlation coefficient = .96–.99). There was a moderate correlation between energy expenditure and total physical activity time with PASE (leisure time activities), PASE (household activities), and PASE (total) (r = .478, r = .468, r = .570, r = .406, r = .490, r = .550, respectively, p < .001). Also, a weak correlation was found between summary and leisurely walking index with PASE (household activities), standing index with PASE (leisure time activities), and PASE (total) (r = .285, p = .010; r = .257, p = .021; r = .238, p = .033; r = .283, p = .010; respectively). The results of the study suggest that the YPAS-TR is a valid and reliable measurement tool that can be used to assess the physical activity patterns of Turkish older adults. © 2023 Human Kinetics, Inc.EnglishAgedExerciseHumansPsychometricsReproducibility of ResultsSurveys and QuestionnairesWalkingagedarticlecontrolled studyconvergent validitycorrelation coefficientenergy expenditurefemalehouseholdhumanhuman experimentmajor clinical studymalephysical activityShort Form 36short physical performance batterysittingtest retest reliabilitywalkingexercisepsychometryquestionnairereproducibilitywalkingArticle10.1123/japa.2022-0207
