The Validity and Reliability of the Turkish Version of Self-Perceived Barriers for Physical Activity Questionnaire.

Identifying the barriers to physical activity (PA) is important for comprehensive management strategies to decrease physical inactivity. This study aimed to translate and cross-culturally adapt the Self-Perceived Barriers for Physical Activity Scale (SPBPA) into Turkish and investigate its psychometric properties. One-hundred fifty-two young and middle-aged adults (mean age of 33.3 ± 12.66 years) were included. Within a 5-to-15-day period after the first assessment, the participants completed the Turkish version of SPBPA (SPBPA-T) to evaluate test-retest reliability. Cronbach's alpha (α) was used to assess internal consistency. The correlation between the SPBPA-T and Physical Activity Barriers Questionnaire (PABQ) and Short Form-12 (SF-12) was determined to check the validity. The SPBPA-T had a strong internal consistency (α = .83) and test-retest reliability (ICC_2,1 = .90). There was a strong correlation between PABQ and SPBPA-T (r = 0.709; p < .0001), indicating strong construct validity. The convergent validity of SPBPA-T was confirmed with the mental component of SF-12 (r = -.228; p < .0001). There was no floor or ceiling effect. The questionnaire had a 1.083 SEM value and its MDC was 3.00 points. The SPBPA-T is semantically and linguistically adequate and has strong internal validity and test-retest reliability to determine the self-perceived barriers to PA among Turkish-speaking young adults.
