Аннотация
BACKGROUND: Emotional blunting (EB), defined as a flattening of emotions and emotional indifference, is reported by many patients with major depressive disorder (MDD) taking antidepressants. Severity of EB correlates with depressive symptoms, as well as deficits in social function, anxiety and health-related quality of life. However, awareness and understanding of EB and its impact on treatment of MDD remain poorly understood.
METHODS: This was a post hoc analysis of data from a web-based survey of 3376 adults with MDD in Japan. The primary endpoint was the correlation between total and subdomain scores of the Oxford Depression Questionnaire (ODQ; a validated instrument to assess EB) and total and individual domain/item scores of the Work and Social Adjustment Scale (WSAS) and Patient Health Questionnaire 9-item (PHQ-9). The secondary endpoint explored which patients had a discrepancy between EB symptoms (assessed by the ODQ) and their own evaluation of EB (using a validated screening question).
RESULTS: There was a moderate correlation between the ODQ total score and the WSAS total score (Spearman's rank correlation coefficient [rs ] = 0.578) and a strong correlation between the ODQ total score and PHQ-9 total score (rs = 0.670). Multiple regression analyses showed that the ODQ subdomains "not caring" (NC) and "reduction in positive emotions" (PR) had the greatest impact on both the WSAS total score (partial regression coefficients = 1.034 and 0.501, respectively) and PHQ-9 total score (partial regression coefficients = 0.548 and 0.592, respectively). A higher proportion of men (versus women) and unemployed individuals (versus employed individuals) underestimated their EB severity compared with their ODQ score.
CONCLUSION: The ODQ subdomains of NC and PR are important factors when evaluating the impact of EB on social function and severity of depressive symptoms in patients with MDD. Physicians should assess EB symptoms for each patient, considering the patient's background.
