Do manualized treatments for depression reduce insomnia symptoms?

OBJECTIVE: Researchers evaluated the effect of manualized treatments for depression on comorbid symptoms of insomnia. METHOD: Hierarchical linear modeling was used to analyze archival data collected from 14 studies (N = 910) examining the efficacy of psychological treatments for depression in adults. RESULTS: Participants receiving a psychological treatment for depression experienced significantly more relief from symptoms of insomnia with overall, early-, middle-, and late-night sleep than those not receiving such treatment. CONCLUSION: Symptoms of insomnia in those with an average (or lower) level of depression can be reduced through psychological treatment for depression. However, more severe depressive symptoms do not receive great relief from sleep disturbance and may require an additional treatment component targeting symptoms of insomnia.

Two-year follow-up of bibliotherapy and individual cognitive therapy for depressed older adults.

This study examined the stability of treatment gains after receiving either cognitive bibliotherapy or individual cognitive psychotherapy for depression in older adults. A 2-year follow-up of 23 participants from Floyd, Scogin, McKendree-Smith, Floyd, and Rokke (2004) was conducted by comparing pre-and posttreatment scores with follow-up scores on the Hamilton Rating Scale for Depression (HRSD) and the Geriatric Depression Scale (GDS). Results indicated that treatment gains from baseline to the 2-year follow-up period were maintained on the HRSD and GDS, and there was not a significant decline from posttreatment to follow-up. There were no significant differences between the treatments on the GDS or HRSD at the 2-year follow-up; however, bibliotherapy participants had significantly more recurrences of depression during the follow-up period.
