Purpose
Depression is a debilitating disease with residual symptoms that negatively impact patients’ quality of life (QoL). Stigma is associated with poor QoL; however, knowledge regarding stigma subtypes and each QoL domain concerning residual depression is limited. We aimed to investigate the association of residual depression symptoms with QoL and stigma among patients with major depressive disorder (MDD).
Methods
This cross-sectional study was conducted at an outpatient clinic among patients with MDD (March–July 2022). We administered the Thai version of the Patient Health Questionnaire-9, World Health Organization Quality of Life Brief, and Mental Health Consumers’ Experience of Stigma to assess patients’ levels of depression, QoL, and personal and perceived stigma, respectively. We performed correlational and logistic regression analyses to evaluate the association of demographics, QoL, stigma, and stress with residual depression.
Results
Of 384 patients with MDD (median age = 39.5, females = 73.2%), 54.4% had residual depression. Among those with residual depression, depression was negatively correlated with QoL (ρ = – 0.58, p < 0.001) and positively correlated with stigma (ρ = 0.24, p < 0.001). The risk of residual depression decreased as the QoL score increased (adjusted OR per 1-point increase 0.93 [0.91, 0.96], p < 0.001); residual depression was significantly associated with personal stigma.
Conclusion
Stigma and QoL exhibit an inverse relationship. Physical-, psychological-, and environmental-health domains of QoL and personal stigma are key contributing factors to residual MDD symptoms. Improvement of QoL and stigma requires further theoretical research and should be of concern in clinical practice. Longitudinal studies on relatively diverse populations and subsyndromal symptoms are needed.
