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

Abstract

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.
