A Home-Based Intervention to Reduce Depressive Symptoms and Improve Quality of Life in Older African Americans

Laura N. Gitlin, Lynn Fields Harris, Megan C. McCoy, Nancy L. Chernett, Laura T. Pizzi, Eric Jutkowitz, Edward Hess, Walter W. Hauck
2013 Annals of Internal Medicine  
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

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.

Mindfulness-Based Intervention for Adolescents with Recurrent Headaches: A Pilot Feasibility Study

Toni Hesse, Laura G. Holmes, Vicki Kennedy-Overfelt, Lynne M. Kerr, Lisa L. Giles
2015 Evidence-Based Complementary and Alternative Medicine  
Recurrent headaches cause significant burden for adolescents and their families. Mindfulness-based interventions (MBIs) have been shown to reduce stress and alter the experience of pain, reduce pain burden, and improve quality of life. Research indicates that MBIs can benefit adults with chronic pain conditions including headaches. A pilot nonrandomized clinical trial was conducted with 20 adolescent females with recurrent headaches. Median class attendance was 7 of 8 total sessions; average

Five participants dropped out for reasons not inherent to the group (e.g., extracurricular scheduling); no adverse events were reported. Parents reported improved quality of life and physical functioning for their child. Adolescent participants reported improved depression symptoms and improved ability to accept their pain rather than trying to control it. MBIs appear safe and feasible for adolescents with recurrent headaches. Although participants did not report decreased frequency or severity of headache following treatment, the treatment had a beneficial effect for depression, quality of life, and acceptance of pain and represents a promising adjunct treatment for adolescents with recurrent headaches.
