Aims: Despite the high incidence of wrong ways to wear a backpack in students, the relevant musculoskeletal complications, and the effective role of health education in modification of this behavior, there is no standard questionnaire in this regard in Iran. The aim of this study was to assess the psychometric evaluation of a questionnaire on backpack carrying among female high school students.
Instruments & Methods: The questionnaire on how female high school students carry their backpack in Babolsar, Mazandaran province included 31 items for knowledge (12 items), attitude (10 items), and behavior (9 items) derived from evidenced literature. This questionnaire was evaluated in terms of content and face validity and reliability through internal consistency and stability in 2018. The qualitative and quantitative content validity was evaluated by the panel of experts through Content Validity Index (CVI) and Content Validity Ratio (CVR). Qualitative and quantitative face validity was assessed by the students’ views and measuring impact score, respectively. Internal consistency and stability were measured by Cronbach’s alpha and Intraclass Correlation Coefficient, respectively. Data were analyzed by SPSS 21.
Findings: The results of CVI (0.9-1), CVR (0.8-1), and impact score (2.5-3) were acceptable for the whole scale. Qualitative content and face validity was favorable. Cronbach’s alpha coefficients were appropriate for the whole scale (0.77) and of knowledge (0.68), attitude (0.8), and behavior (0.77). The interclass correlation coefficient for the whole questionnaire (0.68) and the domains of knowledge (0.61), attitude (0.71), and behavior (0.72) indicated that the questionnaire was acceptable.
Conclusion: The study showed the validity and reliability of the health questionnaire on carrying backpack among female high school students. However, more researches should be done to verify this questionnaire for measuring knowledge, attitude, and behavior regarding backpack carrying.
