The prevalence of depression is high worldwide, and somatic symptoms are known to be one of the most debilitating aspects of depression. However, clinicians often face challenges in accurately assessing this comorbidity. To address this issue, the Depression and Somatic Symptoms Scale (DSSS) was developed as a self-administered scale that can diagnose both depression and somatic symptoms. The objective of this study is to evaluate the validity and reliability of the Arabic-translated version of the DSSS (A-DSSS) in a sample of Lebanese adults, as well as to explore its associated factors. A cross-sectional study was conducted over a period of one month, from February to March 2023, and involved a sample of 422 participants who were aged 18 years or older. Participants completed a questionnaire that included various measures, including demographic characteristics, alcohol and smoking habits, physical activity history, as well as two scales: the Patient Health Questionnaire-9 (PHQ9) scale and the A-DSSS scale. The A-DSSS showed high internal consistency (Cronbach's alpha = 0.936), strong test–retest reliability (ICC of 0.988 with CI 0.976–0.994; p < 0.001), and a three-factor structure consistent with previous research. Convergent validity was supported by a significant correlation with the PHQ-9. Stepwise linear regression revealed that engaging in physical activity and increasing calorie consumption (as measured by MET-min/week score) were associated with a significant decrease in the A-DSSS total score and subscales. However, a significant increase in the A-DSSS total score was seen in the female gender in comparison for male gender. The A-DSSS revealed good psychometric properties and may be a useful tool for assessing depression and somatic symptoms in this population. The study also identified potential factors associated with depression and somatic symptoms, such as physical activity, calorie consumption, and gender, which may have implications in addressing depression and somatic symptoms for future interventions and clinical practice.
