Insights
Men are significantly underrepresented in depression research, participating in only 26% of psychotherapy and lifestyle intervention trials. This lack of male inclusion may hinder effective mental health treatment development for men.
Area of Science:
- Mental Health Research
- Clinical Psychology
- Public Health
Background:
- Major Depressive Disorder (MDD) affects 109 million men globally, with men accounting for 75% of suicides in Western countries.
- Men are less likely to seek mental health support, suggesting current treatments may not be engaging or accessible.
- Underrepresentation of men in clinical trials could impede the development of tailored depression interventions.
Purpose of the Study:
- To quantify male participation in randomized controlled trials (RCTs) for depression.
- To assess the involvement of men in psychotherapy and lifestyle behavior change interventions.
- To identify potential barriers to male engagement in depression research.
Main Methods:
- Systematic review of 110 eligible articles on depression interventions.
- Analysis of participant demographics, focusing on sex representation.
- Examination of intervention characteristics, including delivery mode and sample composition.
Main Results:
- Men constituted only 26% of participants in reviewed depression RCTs, compared to 73% women.
- Male underrepresentation was consistent across various intervention types and delivery methods.
- No studies exclusively sampled men, while 19 studies focused solely on women.
Conclusions:
- Men are substantially underrepresented in research trials for depression.
- Current research practices may not adequately address the needs and accessibility concerns for men in mental health studies.
- Further research is needed to promote male inclusion in clinical trials for depression and improve treatment outcomes.
Abstract:
The prevalence of Major Depressive Disorder in men is half that of women, yet depression affects approximately 109 million men worldwide. Alarmingly, men account for three quarters of suicides in Western countries but are unlikely to seek help for mental health concerns. It is possible that existing mental health treatments are not engaging or accessible to men. The aim of this review was to quantify the number of men involved in randomised trials of psychotherapy or lifestyle behaviour change targeting depression. Results found men represented 26% of participants in 110 eligible articles compared to 73% women. Men's representation was low across all intervention characteristics (e.g., delivery mode). No studies used a completely male sample, compared to 19 studies targeting women only. Men are substantially underrepresented in research trials targeting depression.
