Cognitive-behavioral couple therapy with mindfulness linked to lower depression and better relationship adjustment in low-income couples

The experimental group showed statistically significant improvements in dyadic adjustment (relationship satisfaction and functioning), mindful attention, and depressive symptoms by the end of treatment and at a 3-month follow-up (all p < 0.001, with medium effect sizes of η²p = 0.20–0.37). Marital social skills did not show a significant difference between groups (p = 0.14). Two outcome measures differed between groups at baseline, so researchers confirmed results using sensitivity analyses that adjusted for these differences. The relatively small sample size and short follow-up window (3 months) are important limitations; larger, longer trials are needed to determine whether benefits persist beyond that timeframe and generalize to other low-income populations.

The effect sizes for depression and dyadic adjustment were medium-to-large (η²p = 0.20–0.37), suggesting clinically meaningful change rather than statistical noise alone. Interestingly, improvements in mindful attention and depressive symptoms were closely linked, suggesting that learning to notice thoughts and feelings without judgment may have helped couples disengage from depressive rumination and conflict cycles. The lack of improvement in marital social skills (p = 0.14) hints that the mindfulness component may work more through emotional regulation and stress reduction than through teaching new communication techniques. One limitation is that this was a pilot study with only 17 couples; the control group was waitlisted rather than receiving active placebo, so expectations and therapist attention may have inflated the effect. Additionally, follow-up ended at 3 months, so it's unknown whether gains hold at 6 or 12 months or whether the benefits depend on ongoing practice of home exercises.
