Internalised stigma and self-esteem among adult outpatients with major depressive disorder: A cross-sectional correlational study

Objective: The study aimed to evaluate the internalised stigma and self-esteem in adult outpatients with major depressive disorder (MDD) attending a psychiatric outpatient clinic in Iraq, and to explore the relationship between these variables. Methods: A cross-sectional correlational study among 120 adults with MDD who attended psychiatric outpatient clinics of Azadi Teaching Hospital in Kirkuk, Iraq. All participants filled out a sociodemographic and clinical questionnaire, the Internalised Stigma of Mental Illness Scale (ISMI), and the Rosenberg Self-Esteem Scale (RSES). Data were analysed using descriptive statistics, Pearson's correlation coefficient and simple linear regression. Results: The overall mean ISMI score was 2.90 (SD = 0.42), with the highest scores for stereotype endorsement (M = 3.16) and alienation (M = 3.14) and the lowest for stigma resistance (M = 2.19). The overall mean RSES score was 2.29 (SD = 0.38). There was a negative correlation between internalised stigma and self-esteem (r = −0.338, p < 0.001). Self-esteem was statistically associated with internalised stigma (β = −0.338, t = −3.897, p < 0.001), explaining 11.4% of the variance (R² = 0.114) in simple linear regression. Conclusions: In this single-centre sample of adults with MDD, internalised stigma and self-esteem were inversely related. Since the study is a cross-sectional design, the association observed cannot be considered a causal relationship. The results provide a basis for consideration of the psychosocial aspects of routine psychiatric care (stigma and self-esteem) and for further longitudinal and multicentre research to establish temporal relationships and to determine potentially modifiable factors.
