Valuation of Life as outcome and mediator of a depression intervention for older African Americans: the Get Busy Get Better Trial.

ABSTRACT: Previously, we showed that Get Busy Get Better (GBGB), a 10-session multicomponent home-based, behavioral intervention, reduced depressive symptom severity in older African Americans. As appraising the value of life is associated with depressive symptoms, this study examined whether GBGB enhanced positive appraisals of life and if, in turn, this mediated treatment effects on depressive symptoms.Data were from a single-blind parallel randomized trial involving 208 African Americans (?55 years old) with depressive symptoms (Patient Health Questionnaire, PHQ-9 ?5). GBGB involved five components: care management, referral/linkage, stress reduction, depression education, and behavioral activation. A 13-item Valuation of Life (VOL) scale with two subfactors (optimism and engagement) was examined as an outcome and as mediating GBGB effects on PHQ-9 scores at 4 months.Of 208 enrolled African Americans, 180 completed the 4-month interview (87 = GBGB; 93 = control). At 4 months, compared with wait-list control group participants, the GBGB group had improved VOL (difference in mean changes from baseline = 4.67, 95% confidence interval 2.53, 6.80). Structural equation models indicated that enhanced VOL mediated a significant proportion of GBGB's impact on depressive symptoms, explaining 71% of its total effect, and its subfactors (optimism, explaining 67%; engagement, 52%).Valuation of Life appears malleable through an intervention providing resources and activation skills. GBGB's impact on depressive symptoms is attributed in large part to participants' enhanced attachment to life. Attention to VOL as mediator and outcome and the reciprocal relationship between mood and attachment to life is warranted. Copyright © 2017 John Wiley & Sons, Ltd.

Project description:BackgroundPrimary care is the principle setting for depression treatment; yet many older African Americans in the United States fail to report depressive symptoms or receive the recommended standard of care. Older African Americans are at high risk for depression due to elevated rates of chronic illness, disability and socioeconomic distress. There is an urgent need to develop and test new depression treatments that resonate with minority populations that are hard-to-reach and underserved and to evaluate their cost and cost-effectiveness.Methods/designBeat the Blues (BTB) is a single-blind parallel randomized trial to assess efficacy of a non-pharmacological intervention to reduce depressive symptoms and improve quality of life in 208 African Americans 55+ years old. It involves a collaboration with a senior center whose care management staff screen for depressive symptoms (telephone or in-person) using the Patient Health Questionnaire (PHQ-9). Individuals screened positive (PHQ-9 ≥ 5) on two separate occasions over 2 weeks are referred to local mental health resources and BTB. Interested and eligible participants who consent receive a baseline home interview and then are randomly assigned to receive BTB immediately or 4 months later (wait-list control). All participants are interviewed at 4 (main study endpoint) and 8 months at home by assessors masked to study assignment. Licensed senior center social workers trained in BTB meet with participants at home for up to 10 sessions over 4 months to assess care needs, make referrals/linkages, provide depression education, instruct in stress reduction techniques, and use behavioral activation to identify goals and steps to achieve them. Key outcomes include reduced depressive symptoms (primary), reduced anxiety and functional disability, improved quality of life, and enhanced depression knowledge and behavioral activation (secondary). Fidelity is enhanced through procedure manuals and staff training and monitored by face-to-face supervision and review of taped sessions. Cost and cost effectiveness is being evaluated.DiscussionBTB is designed to bridge gaps in mental health service access and treatments for older African Americans. Treatment components are tailored to specific care needs, depression knowledge, preference for stress reduction techniques, and personal activity goals. Total costs are $584.64/4 months; or $146.16 per participant/per month.Trial registrationClinicalTrials.gov #NCT00511680.

Project description:Effective care models for treating older African Americans with depressive symptoms are needed.To determine whether a home-based intervention alleviates depressive symptoms and improves quality of life in older African Americans.Parallel, randomized trial stratified by recruitment site. Interviewers assessing outcomes were blinded to treatment assignment. (ClinicalTrials.gov: NCT00511680).A senior center and participants' homes from 2008 to 2010.African Americans aged 55 years or older with depressive symptoms.A multicomponent, home-based intervention delivered by social workers or a wait-list control group that received the intervention at 4 months.Self-reported depression severity at 4 months (primary outcome) and depression knowledge, quality of life, behavioral activation, anxiety, function, and remission at 4 and 8 months.Of 208 participants (106 and 102 in the intervention and wait-list groups, respectively), 182 (89 and 93, respectively) completed 4 months and 160 (79 and 81, respectively) completed 8 months. At 4 months, participants in the intervention group showed reduced depression severity (difference in mean change in Patient Health Questionnaire-9 score from baseline, -2.9 [95% CI, -4.6 to -1.2]; difference in mean change in Center for Epidemiologic Studies Depression Scale score from baseline, -3.7 [CI, -5.4 to -2.1]); improved depression knowledge, quality of life, behavioral activation, and anxiety (P < 0.001); and improved function (P = 0.014) compared with wait-list participants. More intervention than wait-list participants entered remission at 4 months (43.8% vs. 26.9%). After treatment, control participants showed benefits similar in magnitude to those of participants in the initial intervention group. Those in the initial intervention group maintained benefits at 8 months.The study had a small sample, short duration, and differential withdrawal rate.A home-based intervention delivered by social workers could reduce depressive symptoms and enhance quality of life in most older African Americans.National Institute of Mental Health.
