Turkish Translation of Physical Activity Barriers and Facilitators Scale; Validity, Reliability, and Cultural Adaptation

Physical Activity Barriers and Facilitators Scale (Arlinghaus et al. 2021) consists of two subscales. Provides information on barriers and facilitators to physical activity among young people. BFFA is a Likert-type scale consisting of 20 items. Items were graded between 1-5 values corresponding to "Never" and "Always" . Written permission to use the scale was obtained for this study and the scale developers sent the scale.

EBBS was developed to assess perceived benefits and perceived barriers to engaging in physical activity. The EBBS consists of two subscales and forty-three questions. Benefits are assessed by 29 items and barriers are assess by 14 items. Participants were asked to rate the perceived benefits and perceived barriers on a 4-point Likert Scale, with the response option ranging from "strongly agree= 4" to "strongly disagree = 1." The possible scores on the benefits scale ranged from 29 to 116 points, with higher scores indicating greater benefits. The possible range of scores on the barriers scale was 14 to 56 points, with a higher score indicating fewer perceived barriers.

Motivation Scale for Participation in Physical Activity was developed by Demir (2018) to measure high school students' motivation to participate in physical activity. MSPPA is a likert-type scale consisting of 16 items. The lowest score that can be obtained from the scale is 16, and the highest score is 80. The high scores of the participants on the scale mean that their motivation to participate in physical activity is positive. In this context, the scores obtained by the participants from the MSPPA indicate that they have 1-16 very low, 17-32 low, 33-48 medium, 49-64 high, 65-80 very high motivation to participate in physical activity. The Cronbach's alpha internal consistency coefficient of the original scale was found to be between 0.82 and 0.89. Spearman Brown split-half reliability coefficients were found to vary between 76 and 89.

The validity and reliability study of the International Physical Activity Questionnaire (IPAQ) in Turkey was carried out by Öztürk in 2005. In our study, the self-administered short form of the questionnaire with 7 questions covering the last 1 week will be used to evaluate the level of physical activity. Calculation of the total score of the short form includes the sum of time (minutes) and frequency (days) of walking, moderate-intensity activity, and vigorous activity. .
