BACKGROUND More Reserve and Guard members have been activated in the past few years than in any other time in history. In addition to the high rates of psychological and behavioral challenges among military personnel, there are other equally important post-deployment reintegration challenges. Post-deployment reintegration challenges are particularly important to Reserve and Guard members, who transition rapidly from civilian-military-civilian. OBJECTIVE This study aims to describe the scope of challenges that a battalion of National Guard members (NGM) report experiencing after returning from a one-year deployment to Iraq. METHOD This article reports data from a sample of 126 NGM who recently returned from a one-year deployment to Iraq. The scope of post-deployment problems at baseline, 3- and 6-month post-deployment are presented. RESULTS Overall, the rates of post-deployment psychological and behavioral problems were elevated upon returning from deployment and remained fairly constant for up to 6 months post-deployment. Approximately 30% of respondents were unsatisfied with their relationship and upwards of 30% reported family reintegration challenges. CONCLUSIONS Comparisons with similar research and implications for prevention and improvement of post-deployment quality of life are addressed.

OBJECTIVE To determine whether evidence-based socioculturally health literate-adapted collaborative depression care improves depression care, depressive symptoms, and quality of life among predominantly Hispanic patients with coronary heart disease. METHODS The 12-month trial included 97 patients with coronary heart disease (79% of eligible patients) who met the depression criteria assessed by the Patient Health Questionnaire-9. Patients were recruited from 3 safety net clinics and offered depression team care by a bilingual clinical social worker and community patient navigator, a consulting psychiatrist, and a primary care physician. The team provided problem-solving therapy (PST) or pharmacotherapy or both, telephone symptom monitoring and behavioral activation, and patient resource navigation support. Recruited patients were given patient and family member health literacy-adapted educational and community resource materials in Spanish or English. RESULTS Overall, depression treatment was 74% (PST, 55%; PST plus antidepressant medications, 18%; and antidepressant medications alone, 2%). Nearly half of the patients showed a 50% reduction of the Symptom Checklist-20 (49% at 6 mo and 48% at 12 mo) and of Patient Health Questionnaire-9 score with 47% of patients at 6 months and 43% at 12 months. The 50% improvement in Patient Health Questionnaire and Symptom Checklist-20 score reduction did not vary significantly between patients who received PST or antidepressant only or those who received PST plus antidepressant. The quality of life Short-Form Health Survey SF-12, the Minnesota Living with Heart Failure questionnaire, and the Sheehan Disability Scale outcomes also improved significantly. CONCLUSIONS Socioculturally literacy-adapted collaborative depression care was accepted by patients with coronary heart disease and improved depression care and symptoms, quality of life, and functional outcomes among predominantly Hispanic patients with heart disease.

Social Support, a Mediator in Collaborative Depression Care for Cancer Patients

Hyunsung Oh; Kathleen Ell

Objective: This study assessed whether perceived social support (PSS) is a factor in improving physical and functional well-being observed among cancer patients receiving collaborative depression care. Methods: A secondary analysis was conducted of data collected in a randomized clinical trial testing the effectiveness of collaborative depression care. PSS was measured at 12 months; physical and functional well-being were assessed at 18 and 24 months post-baseline. Mediation analyses via a bootstrapping method were conducted. Results: Significant mediation of PSS at 12 months predicted better physical and functional well-being at 18 months and 24 months. Conclusion: Depressed cancer survivors are likely to benefit when social workers provide psychosocial depression care aimed at activating social support, thereby improving physical and functional well-being.

Depression remission, receipt of problem-solving therapy, and self-care behavior frequency among low-income, predominantly Hispanic diabetes patients

Hyunsung Oh; Kathleen Ell

OBJECTIVE This study explored whether depression remission and problem-solving therapy (PST) receipt are associated with more frequent self-care behaviors via cross-sectional and prospective analyses. METHOD We analyzed data from a randomized clinical trial (N=387) that tested collaborative depression care among predominantly Hispanic patients with diabetes in safety-net clinics. Data at 12-month follow-up, measured with the Patient Health Questionnaire-9 and Hopkins Symptom Checklist-20, were used to define depression remission. PST was provided by a bilingual social worker. Multivariate regression analysis was used to examine associations between predictors and frequency change of each self-care behavior (healthy diet, exercise, self-blood glucose monitoring, and foot care between baseline and 12-month (N=281), 18-month (N=249), and 24-month (N=235) follow-up surveys. RESULTS Inconsistent relationships were observed depending on the instrument to identify depression remission, type of self-care behaviors, and time when self-care behavior was measured. Significant associations were more likely to be observed in cross-sectional analyses. PST receipt was not associated with self-care behaviors. CONCLUSIONS Depression remission or the receipt of PST may not be a reliable antecedent for more frequent self-care behaviors among this group. A few recommendations for studies were offered to enhance existing depression care for diabetes patients.

The study evaluated depression and self-care management among patients with diabetes and/or heart disease in a 12-month randomized trial conducted in Los Angeles County Department of Health Services (LAC-DHS) community clinics. We compared LAC-DHS clinic usual care (UC) versus A-Helping-Hand (AHH) intervention in which bilingual promotoras, hired and supervised by the research project, provided 6 weekly psychoeducational sessions followed by boosters. Of 1957 screened, 348 depressed patients (PHQ-9 score≥10) were enrolled, randomized to AHH (n=178) or UC (n=170) after baseline interview assessing mental health, treatment receipt, co-morbid illness, self-care management, and environmental stressors. Comprehensive assessments were repeated at 6 and 12months by an independent interviewer blind to the study group. Patients (85% diabetes, 4% heart disease, 11% both) were predominantly female (85%), Latino (99%), born outside of the US (91%). Study attrition at 12months was 30% (AHH 31%, UC 28%, P=0.51). No baseline characteristics were associated with attrition. Half of AHH patients received 4 or more sessions. Intend-to-treat analysis found study groups did not vary significantly at 6 and 12months. Before-after paired t-tests showed significant improvements in most measures in each group. During the trial, LAC-DHS activated healthcare improvements including depression screening, referral to clinic staff including community health workers (with the same role as the promotoras) to improve patient care management. Both patient groups performed equally well which may be a function of the enhanced healthcare model. Future research should replicate the promotora-integrated care model with other groups and care settings with similar comorbid conditions.

Integrating Biopsychosocial Intervention Research in a Changing Health Care Landscape

Kathleen Ell; Hyunsung Oh; Shinyi Wu

Objective: Safety net care systems are experiencing unprecedented change from the Affordable Care Act, Patient-Centered Medical Home (PCMH) uptake, health information technology application, and growing of mental health care integration within primary care. This article provides a review of previous and current efforts in which social workers deliver biopsychosocial depression care. Method: Recent research trials tested biopsychosocial care for patients with major depression and concurrent illness and technology-facilitated patient–provider and provider–provider communication within the Los Angeles County Department of Health Services (DHS). In addition, qualitative studies assessed patient, social worker, and medical provider perceptions. Results: DHS has recently activated its PCMH model, technology applications aimed at facilitating cross-provider communication, and the integration of colocated social workers. Conclusions: This article demonstrates both need and opportunity to develop, apply, and test social work integrated biopsychosocial and technology activated care within a large safety net care system.

Depression frequently negatively affects patient overall self-care and social stress management within United States safety net care systems. Rates of major depression are significantly high among low-income predominantly Hispanic/Latino with chronic illness, such as diabetes and heart disease. The study design of the A Helping Hand to Activate Patient-Centered Depression Care among Low-income Patients (AHH) randomized clinical trial aims to enhance patient depression care receipt and overall bio-psychosocial self-care management. The AHH trial is conducted in collaboration with three Los Angeles County Department of Health Services (DHS) safety net clinics that provide Patient-Centered Medical Home (PCMH) care. The study compares AHH intervention (AHH) in which community-based bilingual promotoras provide in-person or telephone patient engagement and intervention aimed to reduce the burden and strain on patients, families, and care providers by assessing, enhancing, and facilitating patient depression and co-morbid illness self-care management skill, and activating patient communication with clinic medical providers versus DHS PCMH team usual care (PCMHUC). AHH independent bilingual recruiters screened 1957 and enrolled 348 predominantly Hispanic/Latino patients, of whom 296 (85%) had diabetes, 14 (4%) with heart disease, and 38 (11%) with both diseases. Recruiters identified depressed patients by baseline Patient Health Questionnaire-9 scores of 10 or more, completed baseline assessments, and randomized patients to either AHH or PCMHUC study group. The comprehensive assessments will be repeated at 6 and 12months by an independent bilingual follow-up interviewer. Baseline and outcome data include mental health assessment and treatment receipt, co-morbid illness self-care, social relationships, and environmental stressor assessments.

Associations Between Changes in Depressive Symptoms and Social Support and Diabetes Management Among Low-Income, Predominantly Hispanic Patients in Patient-Centered Care

Hyunsung Oh; Kathleen Ell

OBJECTIVE This study examined whether changes in depressive symptoms and social support prospectively predicted diabetes management among Hispanic patients with probable depression in patient-centered medical homes at safety-net clinics in East Los Angeles, CA. RESEARCH DESIGN AND METHODS Data were collected from 251 patients enrolled in a randomized clinical trial testing the effectiveness of a self-management intervention assisted by a promotora (Hispanic community health worker). Cross-lagged analyses examined associations between changes in depression symptoms and social support between baseline and 6-month follow-up and self-efficacy and adherence to diabetes management at the 6- and 12-month follow-ups. RESULTS Changes in depressive symptoms predicted self-efficacy and level of adherence at the 6- and 12-month follow-ups. Changes in total social support and emotional social support were correlated only with self-efficacy regarding diabetes management at 6-month follow-up. CONCLUSIONS Decline in depressive symptoms is a reliable predictor of improvement in self-efficacy and adherence to diabetes management. Further studies are recommended to study psychosocial mechanisms related to social relationships other than social support that affect diabetes management.

The Bidirectional Relationship Between Depressive Symptoms and Homebound Status Among Older Adults

Xiaoling Xiang; Ruopeng An; Hyunsung Oh

Objectives This study aimed to examine the bidirectional relationship between depressive symptoms and homebound status among older adults. Method The study sample included 7,603 community-dwelling older adults from the National Health and Aging Trends Study. A bivariate latent state-trait model of depressive symptoms and homebound status was estimated via structural equation modeling. Results The model fit the data well (Root Mean Square Error of Approximation = .02, Comparative Fit Index = .97, Standardized Root Mean Square Residual = .06). The relationship between homebound status and depressive symptoms can be decomposed into three parts: a moderate correlation between the stable trait components (r = .56, p <.001); a contemporary association of the state components (b = .17, p <.001); and bidirectional lagged effects between the state components. Change in homebound status was as a stronger predictor of depressive symptoms (b = .19, p < .001) than change in depressive symptoms was of homebound status (b = .06, p < .001; test of difference: Δ scaled χ2(1) = 24.2, p < .001). Discussion Homebound status and depressive symptoms form a feedback loop to influence each other. Improving the outdoor mobility of older adults may have immediate benefits for reducing depressive symptoms.

Self-care behavior change and depression among low-income predominantly Hispanic patients in safety-net clinics

Hyunsung Oh; Kathleen Ell; Lawrence A. Palinkas

ABSTRACT This study examined whether changes in self-care behaviors during a 12-month period predicted the likelihood of screening positive for depression concurrently and prospectively among low-income Hispanic patients with diabetes. Secondary analyses were conducted with longitudinal data collected from a randomized controlled trial that had tested effectiveness of collaborative depression care. We examined whether changes in self-care behaviors observed during the 12 months after baseline predicted the likelihood of screening positive for depression at 12-, 18-, and 24-month follow-up. Self-care behaviors included healthy diet, exercise, self-blood glucose monitoring, and foot care, which were measured by a validated self-reported instrument. Logistic regression analyses indicated that patients with more frequent healthy diet during the 12 months after baseline had significantly lower likelihood of depression. Patients with more frequent exercise had a lower likelihood of screening for depression at 18- and 24-month follow-up. No significant association was found with self-blood glucose monitoring and foot care. These findings suggest the importance of integrated care that emphasizes healthy diet and exercise, together with traditional depression treatment, when helping low-income Hispanic patients with diabetes and comorbid depression.
