Mental Defeat Predicts Increased Suicide Risk in Chronic Pain: A 12-Month Prospective Study

Area of Science:

• Psychiatry
• Pain Medicine
• Clinical Psychology

Background:

• Mental defeat is a recognized risk factor for suicidal ideation and behaviors, particularly in individuals experiencing chronic pain.
• The interplay between mental defeat, depression, and suicide risk in chronic pain populations requires further investigation.

Purpose of the Study:

• To evaluate the predictive role of mental defeat in future suicide risk among chronic pain patients.
• To examine the moderating effect of depression on the relationship between mental defeat and suicide risk.

Main Methods:

• A longitudinal study involving 340 chronic pain participants assessed over 12 months.
• Data collection included sociodemographic, pain, mental defeat, depression, and health-related variables.
• Weighted univariate and multivariable analyses, including moderation analysis, were employed.

Main Results:

• Elevated levels of mental defeat and depression were independently associated with increased suicide risk at 12-month follow-up.
• Depression significantly amplified the association between mental defeat and suicide risk, demonstrating a dose-response relationship.
• The impact of mental defeat on suicide risk was notably stronger in individuals with higher depression severity.

Conclusions:

• Mental defeat is a significant, independent predictor of suicide risk in chronic pain.
• Depression exacerbates the link between mental defeat and suicide risk, underscoring the importance of addressing both concurrently.
• Integrated treatment strategies targeting both mental defeat and depression are crucial for mitigating suicide risk in chronic pain patients.
