Adaptation of Brunel Lifestyle Physical Activity Questionnaire into Turkish; The Validity and Reliability Study

Abstract

Background: This study aims to investigate the reliability and validity of the Turkish version of the Brunel Lifestyle Physical Activity Questionnaire (BLPAQ) and examine the cultural adaptation of the questionnaire.Methods: After the translation process, the test-retest reliability of the Turkish version of the questionnaire was analyzed with 24 (31.20±5.0 years old; 50% female) participants (2nd test was done 15 days after the first test). In addition, the validity of the scale was evaluated by the correlation between the BLPAQ and the International Physical Activity Questionnaire Short Form (IPAQ-SF) completed by 113 (30.59±5.40 years old; 63.7% Female) participants.Results: A powerful positive and significant correlation was found between the correlation coefficients of the BLPAQ's PPA and UPA subscales between both tests (respectively r=0.96, p<0.01; r=0.87, p<0.01). The Cronbach's alpha coefficient was found to be 0.77 (quite reliable). The PPA subscale of the BLPAQ was positive with the IPAQ-SF's high-intensity physical activity subscale (r=0.47 p=0.00) and total IPAQ-SF excluding sitting (r=0.50 p=0.00) medium in the direction and low positive correlation with the walking activity subscale (r=0.25 p=0.024). No significant correlation was found between the UPA subdivision of BLPAQ and IPAQ-SF (p>0.05).Conclusion: BLPAQ, adapted into Turkish, is a valid and reliable tool that can be used to determine lifestyle according to physical activity level.
