Cognitive, behavioural or cognitive-behavioural self-help interventions for subclinical depression in older adults: A systematic review and meta-analysis.

BACKGROUND

Subclinical depression is a risk factor for the development of major depression in older adults. We aimed to determine the effectiveness of pure self-help or self-help with minimal support to reduce depressive symptoms and to prevent the onset of major depression in this population.

METHODS

This was a systematic review and meta-analysis of trials that used self-administrated cognitive, behavioural or cognitive-behavioural interventions for older adults with subclinical depression compared to control groups. Medline, Embase, PsycInfo and Cochrane databases were searched for relevant studies.

RESULTS

We analysed eight trials involving 1449 participants. A small but significant effect favouring the intervention was found at short-term [d = 0.33; 95% CI (Confidence Interval): 0.20-0.47] and at long-term (d = 0.22; 95% CI: 0.04-0.40) for depressive symptoms. None of the studies looked at the preventive effect of self-help interventions in reducing the probability of a subsequent diagnosis of major depression.

LIMITATIONS

The low number of studies meant that it was not possible to test for publication bias. The absence of pre-published protocols for many of the studies meant that there is a possibility of selective reporting bias for some of the primary studies.

CONCLUSIONS

There is some evidence that cognitive-behavioural self-help interventions may reduce depressive symptoms in older adults with subclinical depression. However, no study examined whether the intervention had a preventative effect in reducing the likelihood of a subsequent diagnosis of major depression.
