Abstract

Objective: To determine the prevalence of somatic symptoms among patients with major depressive disorders and the association between somatic symptoms and the severity of major depressive disorder among outpatients receiving care at Suanprung Psychiatric Hospital, Chiangmai province.


Materials and methods: This analytical cross-sectional study was conducted among newly diagnosed outpatients with major depressive disorder aged ≥20 years, diagnosed according to ICD-10 criteria between January and May 2025. Somatic symptoms were assessed using the Thai version of PHQ-15. Data were analyzed using the chi-square test and multivariate logistic regression.


Results: A total of 230 participants were included. The prevalence of somatic symptoms was 96.96%. The most common symptoms were sleep problems (92.17%), fatigue or low energy (81.74%), and headache (76.96%) respectively. Most participants had a medium level of somatic symptom severity (38.26%). Regarding depression severity, most patients were classified as having a severe depressive episode without psychotic symptoms (68.26%). Factors predicting severe depression included age ≤40 years (OR 1.85, p=0.05), duration of illness <4 months (OR 2.35, p=0.01), and medium-to-high somatic symptom severity (OR 1.92, p=0.04).


Conclusion: Patients with major depressive disorder receiving care have a high prevalence of somatic symptoms, which are significantly associated with depression severity.
A systematic assessment of somatic symptoms using the PHQ-15 alongside clinical evaluation may facilitate earlier identification and screening of patients at risk for severe depression.
