Prevention of late-life anxiety and depression has sustained effects over 24 months: A pragmatic randomized trial.

Objective: Depressive and anxiety disorders in later life have a high incidence and are associated with reduced quality of life. Elsewhere, we demonstrated that a stepped-care prevention approach was successful in halving the incidence of these disorders over a period of 12 months. As a decreasing effect over time is to be expected, our aim was to investigate the longer-term effects. Design: Randomized controlled trial. Setting: Thirty-three primary care practices in the Netherlands. Participants: One hundred seventy consenting individuals, age 75 years and older, presenting with subthreshold depression or anxiety, not meeting the diagnostic criteria. Intervention: Participants were randomized to a preventive intervention or usual care. In the first 12 months, the preventive intervention entailed watchful waiting, minimally supported CBT-based self-help intervention, problem-solving treatment, and referral to a primary care physician for medication, if required. In the last 12 months, 95% of the participants ceased to receive such support. Measurements: Mini International Neuropsychiatric Interview. Results: The cumulative incidence rate of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, major depression or anxiety disorder over a period of 24 months was halved by the intervention, from 33 of 84 (39.3%) in the usual care group to 17 of 86 (19.8%) in the intervention group (odds ratio = 0.38; 95% confidence interval = 0.19-0.76), which was significant (z = 2.75; p = 0.006). The corresponding number needed to treat was 5 (95% confidence interval = 3-16). Conclusions: A stepped-care approach to the prevention of depression and anxiety in late life was not only successful in halving the incidence of depressive and anxiety disorders after 1 year, but these favorable effects were also sustained over 24 months. © 2011 American Association for Geriatric Psychiatry

How effective is bibliotherapy for very old adults with subthreshold depression? A randomized controlled trial

Objectives: Depressive symptoms are common among elderly primary care patients, and because they encounter considerable barriers in seeking help and they often resist referral to specialized mental health facilities, it is important to look for easily accessible interventions within the primary care setting. Bibliotherapy, which has been found to be effective among younger populations, might be an attractive option. In this study, the authors investigated the effectiveness of bibliotherapy for depressive symptomatology in very old adults. Design: Randomized controlled trial. After a 3-month period of "watchful waiting," the participants were randomly assigned to a bibliotherapy group or a usual care group. Setting: Thirty-three general practices in the north-western region of the Netherlands. Participants: One hundred seventy community-dwelling adults, aged 75 and older, with subthreshold depression. Intervention: The bibliotherapy intervention consisted of an information leaflet and a self-help manual "Coping with Depression" adapted for the elderly. Measurements: Outcome measures after 3 months were a) change in depressive symptoms according to the Center for Epidemiologic Studies Depression Scale (CES-D) and b) the proportion of participants who scored a significant improvement on the CES-D. Results: One hundred forty-six (85.9%) of the 170 participants completed the baseline and follow-up measurements. The authors did not find any clinically relevant and statistically significant differences between the intervention group and the control group in the severity of the depressive symptoms. Conclusion: Bibliotherapy as a stand-alone intervention for the elderly (aged 75 years and older) did not reduce depressive symptoms more than usual care. This might indicate that bibliotherapy can only be effective for patients who are motivated and acknowledge their depression. © 2011 American Association for Geriatric Psychiatry

Pulling out all the stops: what motivates 65+ year olds with depressive symptoms to participate in an outreaching preference-led intervention programme?

OBJECTIVES: Many older adults have significant depressive symptoms but few people access care for these. This study explores which personal, clinical and need factors facilitate or hinder acceptance of a new outreaching preference-led intervention programme.METHODS: From a sample of 9661 community-dwelling 65+ year olds, 244 persons with depressive symptoms according to the Patient Health Questionnaire-9 were included. Data on programme effectiveness in terms of care utilisation were collected. Associations between programme acceptance and personal, clinical and need factors were studied using quantitative (logistic regression analyses) and qualitative methods (semi-structured interviews with 26 subjects, who accepted (n = 20) or declined (n = 6) the programme).RESULTS: Fifty-six per cent (n = 137) took part in the interventions. Quantitative logistic regression analyses showed that participants were more often female, suffered from more severe depressive symptoms and perceived more loneliness. Qualitative analyses revealed that people accepting the intervention programme felt that medical terms as having a depressed mood were applicable to their situation, more often perceived their symptoms as hindering, felt lonely and more often perceived a need for care. They were more often advised by their general practitioner to participate than individuals who refused the interventions. Many participating individuals did not see a match between the intervention programme and their needs, especially with respect to meeting new people.CONCLUSION: Many older persons with depressive symptoms did not feel the need to take part in the programme. Providing support in alleviating loneliness and further adaptation to older adults' illness representations and perceptions when discussing depressive symptoms might enhance care utilisation
