Psychometric Properties of the Turkish Version of Time Organization and Participation Scale

Standardized assessment tools are crucial for evaluating time organization in daily tasks. This study aimed to adapt the Time Organization and Participation Scale (TOPS) into Turkish and assess its psychometric properties. A total of 250 participants (72 individuals with disabilities and 178 without disabilities) completed a sociodemographic form, Turkish version of the Time Organization and Participation Scale (TOPS-TR), the Time Management Questionnaire (TMQ), and the World Health Organization Disability Assessment Schedule (WHODAS-2.0). The TOPS-TR consisted of 25 items, and three factors explained 63.33% of the total variance. Confirmatory factor analysis showed that the scale had acceptable validity (root mean square error of approximation (RMSEA):0.071, Non-normed fit index (NNFI):0.902, comparative fit index (CFI):0.918, incremental fit index (IFI):0.920, Chi-square/Degrees of Freedom (CMIN/DF):1.185-. Convergent construct validity showed a correlation between the TOPS-TR and TMQ and WHODAS-2.0. The scale demonstrated excellent internal consistency (Cronbach's α = 0.931). The TOPS-TR is a valid and reliable tool for assessing time organization and participation in Turkish adults.
