THE RELIABILITY AND VALIDITY OF THE TURKISH VERSION OF THE EUROPEAN HEALTH INTERVIEW SURVEY-PHYSICAL ACTIVITY QUESTIONNAIRE (EHIS-PAQ)

Abstract

Purpose: To translate and adapt the Turkish version of the EHIS-PAQ and to evaluate its reliability and validity in young adults. Methods: A total of 431 young adults were assessed with the Turkish version of the EHIS-PAQ and International Physical Activity Questionnaire-Short Form (IPAQ-SF). One week later, 117 participants refilled the Turkish EHIS-PAQ for the test-retest reliability. Reproducibility and construct validity was analyzed with intraclass correlation coefficient (ICC) and Pearson correlation coefficient, respectively. Besides, standard error of measurement (SEM95) and minimal detectable change (MDC95) were calculated for the Turkish EHIS-PAQ.

Results: The mean age of the participants were 21.2 +/- 9.8 years. The ICC score for the total Physical Activity (PA) of Turkish EHIS-PAQ was 0.873 (CI:0.81-0.91). Test-retest reliability for the total score was excellent (ICC>0.80). The highest correlation was observed between the walking minute value of Turkish EHIS-PAQ and the walking PA sub-score of IPAQ-SF, as expected (r=0.625, p<0.001). There was also a strong correlation between the Transportation-related PA subscore of the Turkish EHIS-PAQ and IPAQ-SF's Walking PA score (r=0.592, p<0.001). SEM95 and MDC95 for the Transportation-related PA were 172.5 and 476.8, respectively. Conclusion: The Turkish version of the EHIS-PAQ is a valid and reliable questionnaire in young adults.
