The Effectiveness of Cognitive Behavioral Therapy for Depression Among Individuals with Diabetes: a Systematic Review and Meta-Analysis.

PURPOSE OF REVIEW: Depression is prevalent and common among individuals living with diabetes. The aim of this review is to systematically assess and meta-analyze the treatment effect of cognitive-behavioral therapy for depression (and other affective outcomes) among patients with diabetes. RECENT FINDINGS: Earlier investigations found both psychosocial and pharmacological interventions, including cognitive-behavioral therapy, were promising in managing depression in patients with diabetes, though these findings remain inclusive due to poor study designs and a small number of trials included, which calls for a comprehensive systematic review and meta-analysis. A total of 33 studies (89 effect sizes) reported a moderate and statistically significant treatment effect of cognitive-behavioral therapy for depressive symptoms among individuals with diabetes (d = 0.301, 95% CI 0.115-0.487, p < 0.001). On average, cognitive-behavioral therapy was effective for psychological stress/distress outcomes but not for anxiety or physiological outcomes. The findings of the study confirmed CBT as an effective treatment option for depression among diabetes patients and identified important areas for future research.

The effectiveness of modified, group-based CBT for dementia worry among Chinese elders.

OBJECTIVES: Dementias are highly prevalent among Chinese elders. This study examined the effectiveness of a modified group cognitive behavioral therapy (CBT) on dementia worry among Chinese older adults. METHODS: Eighty-two older adults recruited from four elder group homes were randomly assigned to either intervention or control group. The intervention group (n= 44) received eight weekly 60-minute face-to-face CBT, while the control group (n=38) received treatment-as-usual. RESULTS: Outcomes indicated that the modified group CBT has significantly reduced dementia worry and culturally biased beliefs about dementia (p<.001). Study findings supported both statistically and clinically significant effect of modified group CBT on dementia worry [g=-1.52, 95% CI (-2.01, -1.03)] and biased beliefs about dementia [g=-.95, 95% CI (-1.40, -.49)]. DISCUSSION: The culturally adapted CBT is promising in alleviating worries and anxiety over dementia among Chinese older adults. Future research needs to include larger samples and participants from different regions to replicate findings.
