Can Problem Solving Therapy Solve the Problem of Late Life Depression? A Systematic Review of Randomized Trials

Clinical depression affects approximately a fifth of older adults. It is important to assess the efficacy of psychological interventions in older adults because extant research indicates that treating depression with medication becomes complicated in later life. The current study evaluates the efficacy and long term effects of problem solving therapy (PST) by systematically reviewing randomized trials of PST. A systematic search was undertaken of three computerised databases and six studies met the inclusion criteria. Studies indicated that PST was more effective than control conditions. However, the direct and long term effect of PST on depressive symptoms remains difficult to establish due to methodological issues.
