- Description: Background: Higher levels of insomnia predict greater depression severity among older adults; however. The psychological mechanisms underlying this relationship are unclear. This study tested a path model that explored whether dysfunctional beliefs about sleep and hopelessness mediate. The relationship from insomnia to depression. It was hypothesized that insomnia would predict depression, both directly and indirectly, via dysfunctional beliefs about sleep and hopelessness. Methods: A community sample of 218 independent-living Australian older adults aged from 65 to 96 years completed a self-report questionnaire package. From the initial 218 participants, 171 completed a measure of depression three months later. Results: Path analysis demonstrated that maladaptive sleep beliefs and hopelessness partly explained how insomnia influenced depression, irrespective of the presence of obstructive sleep apnea and/or restless legs syndrome. Conclusions: An older adult's beliefs about sleep and sense of hopelessness were important psychological factors that helped explain how insomnia related to depression. © 2013 International Psychogeriatric Association.

- Description: Study Objectives: To investigate whether cognitive behavior therapy was effective for older adults with comorbid insomnia and depression in a community mental health setting, and explore whether an advanced form of cognitive behavior therapy for insomnia produced better outcomes compared to a standard form of cognitive behavior therapy for insomnia. Methods: An 8-week randomized controlled clinical trial was conducted within community mental health services, Victoria, Australia. Seventy-two older adults (56% female, M age 75 ± 7 years) with diagnosed comorbid insomnia and depression participated. Three conditions were tested using a group therapy format: cognitive behavior therapy for insomnia (CBT-I, standard), cognitive behavior therapy for insomnia plus positive mood strategies (CBT-I+, advanced), psychoeducation control group (PCG, control). The primary outcomes were insomnia severity (Insomnia Severity Index) and depression severity (Geriatric Depression Scale). Primary and secondary measures were collected at pre (week 0), post (week 8), and follow-up (week 20). Results: CBT-I and CBT-I+ both generated significantly greater reductions in insomnia and depression severity compared to PCG from pre to post (p < .001), which were maintained at follow-up. Although the differences between outcomes of the two treatment conditions were not statistically significant, the study was not sufficiently powered to detect either superiority of one treatment or equivalence of the two treatment conditions. Conclusion: CBT-I and CBT-I+ were both effective at reducing insomnia and depression severity for older adults. Mental health services that deliver treatment for comorbid insomnia with cognitive behavior therapy may improve recovery outcomes for older adults with depression.

- Description: Objectives: To explore the experiences of older adults who participated in a randomised controlled trial (RCT) that tested cognitive behaviour therapy for insomnia and depression. Methods: Focus groups were conducted post treatment for older adults (M age = 75 years; 61% female) who participated in a RCT that tested two experiential interventions targeting comorbid insomnia and depression (cognitive behaviour therapy for insomnia, CBT-I; cognitive behaviour therapy for insomnia plus positive mood strategies, CBT-I+). Six semi-structured focus group interviews (N = 31) were analysed using a qualitative thematic analysis. Results: Interview data were transcribed into 424 sentences and 60 codes were extracted. Thirty-four initial themes emerged, which were transformed into 3 themes and 10 subthemes. The three primary themes were (1) positive experiences, (2) negative experiences, and (3) suggested modifications. The positive subthemes were (1a) therapists, (1b) togetherness, (1c) use of strategies reduced symptoms, and (1d) acceptance. The negative subthemes were (2a) persistent symptoms, (2b) program too condensed, and (2c) attendance obstacles. The suggested modifications were (3a) lengthen program, (3b) multi-dimensional learning, and (3c) multi-modal delivery options. Conclusion: The experiences and suggestions identified in this study strengthen the foundation to advance therapeutic program development for older adults with comorbid insomnia and depression. Future CBT-I programs for older adults may be improved by increasing the length of therapy (e.g. 8 sessions to 12 sessions), adding multi-dimensional learning opportunities (e.g. visual/audio/mentorship), and offering various modes of treatment delivery (e.g. group, individual, internet, telephone). © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.
