ABSTRACT
Background
Post-stroke anxiety and depression can be disabling and result in impaired recovery. Cognitive-behavioral therapy (CBT) has been demonstrated to be effective for anxiety and depression; however, determining its efficacy among those with stroke is warranted. Our objectives to evaluate CBT for anxiety and depression post-stroke .
Methods
This review was registered with PROSPERO (REG# CRD42020186324). Medline, PsycInfo, and EMBR Cochrane were used to locate studies published before May 2020, using keywords such as stroke and CBT. A study was included if: (1) interventions were CBT-based, targeting anxiety and/or depression; (2) participants experienced a stroke at least 3 months previous; (3) participants were at least 18 years old. Standardized mean differences ± standard errors and 95% confidence intervals were calculated, and heterogeneity was determined. The Cochrane Risk of Bias tool was used.
Results
The search yielded 563 articles, of which 10 (N = 672) were included;6 were randomized controlled trials. Primary reasons for exclusion included: (1) wrong population (2) insufficient data provided for a meta-analysis; (3) wrongoutcomes. CBT showed large effects on reducing overall anxiety (SMD ± SE: 1.01 ± 0.32, p < .001) and depression (SMD ± SE: 0.95 ± 0.22, p < .000) symptoms at the end of the studies. CBT moderately maintained anxiety (SDM ± SE: 0.779 ± 0.348, p ˂.025) and depression (SDM ± SE: 0.622 ± 0.285, p ˂ .029) scores after 3-months. Limitations included small sample size, limited comparators, and lack of follow-up data.
Conclusion
The results of this meta-analysis provide substantial evidence for the use of CBTto manage post-stroke anxiety and depression.
Disclosure statement
No potential conflict of interest was reported by the author(s).
Impact
There is limited evidence for the management of mood and anxiety symptoms post-stroke through community-based CBT programs.
The current paper provides an up-to-date synthesis of current literature for the effectiveness of CBT interventions among those post-stroke.
This paper highlights factors that may influence long term outcomes, such as group-based versus individual-based therapy, intervention duration, comparator group, and intervention leader.
Current gaps in literature are identified and recommendations for future research are provided, including having pharmacotherapy as a comparator, including a more representative sample of the population, and having longer term follow-ups.
