THE CULTURAL ADAPTATION, RELIABILITY AND VALIDITY OF THE TURKISH VERSION OF THE SIMPLE PHYSICAL ACTIVITY QUESTIONNAIRE IN COMMON MENTAL DISORDERS

Abstract

Purpose: The aim of this study is to evaluate the validity and reliability of the Turkish version of the Simple Physical Activity Questionnaire (SIMPAQ) in patients with common mental disorders. Methods: A total of eighty-one patients (mean age: 40.14 ± 13.05 years) were included in this study. The Turkish version of the SIMPAQ was used to evaluate the physical activity levels and sedentary behaviors of the participants. To be used as descriptive data, DSM-5 Level 1 Cross-Cutting Symptom Measure-Adult was used to evaluate mental health symptomatology. International Physical Activity Questionnaire-Short Form (UFAA-SF) and Brief Psychiatric Rating Scale (BPRS) were used to test validity of the questionnaire. Results: The items of Turkish version of the SIMPAQ exhibited excellent intercorrelation coefficient (ICC) values (time spent in bed (0.93 (95% CI: 0.90-0.96)), sedentary time 0.87 (95% CI: 0.80-0.92), walking time 0.98 (95% CI: 0.98-0.99), exercise time 0.99 (95% CI: 0.99-0.99), and incidental activity time 0.95 (95% CI: 0.92-0.97)). However, the BPRS had a significant correlation with only the sedentary time of the SIMPAQ (rho=0.25, p=0.02), indicating convergent validity was poor. Conclusion: The Turkish version of the SIMPAQ is semantically and linguistically adequate to quickly assess physical activity level and sedentary behavior in patients with common mental disorders.
