OBJECTIVE: Major Depressive Disorder (MDD) represents a significant global health challenge, with elevated risks of suicidal ideation. This study evaluated the efficacy of Mindfulness-Based Cognitive Therapy (MBCT) in mitigating depressive symptoms and suicidal ideation among institutionalized patients with MDD in Nigeria.
METHOD: A randomized controlled trial was conducted with 101 participants (MBCT: n = 50, Control: n = 51) in two psychiatric institutions in northern Nigeria. The 8-week MBCT intervention was compared to standard pharmacological care. Outcomes were assessed at baseline, week 4, week 8 (primary endpoint), and 3-month follow-up using the BDI-II and BSI. The primary analysis used linear mixed-effects models; repeated-measures ANOVA was conducted as a supplementary analysis.
RESULT: MBCT significantly reduced BDI-II scores compared to controls at week 8 (between-group difference: -9.4, 95% CI: -12.0 to -6.8, p < 0.001) and 3-month follow-up (-6.7, 95% CI: -9.5 to -3.9, p < 0.001). Similar reductions were observed in BSI scores at week 8 (-5.7, 95% CI: -7.7 to -3.7, p < 0.001) and follow-up (-3.9, 95% CI: -6.0 to -1.8, p < 0.001). Large effect sizes were observed for both measures (Cohen's d: 0.92-1.38). MBCT demonstrated significant efficacy in reducing depressive symptoms and suicidal ideation among institutionalised Nigerian patients with MDD, with effects maintained at 3-month follow-up.
CONCLUSION: These findings suggest that MBCT is a promising adjunct to standard care for institutionalized patients with MDD in this setting. Larger, multisite trials with active comparators are warranted before broader clinical integration in LMICs is recommended.
