Evaluating effectiveness of public health intervention strategies for mitigating COVID-19 pandemic.

Coronavirus disease 2019 (COVID-19) pandemic is an unprecedented global public health challenge. In the United States (US), state governments have implemented various non-pharmaceutical interventions (NPIs), such as physical distance closure (lockdown), stay-at-home order, mandatory facial mask in public in response to the rapid spread of COVID-19. To evaluate the effectiveness of these NPIs, we propose a nested case-control design with propensity score weighting under the quasi-experiment framework to estimate the average intervention effect on disease transmission across states. We further develop a method to test for factors that moderate intervention effect to assist precision public health intervention. Our method takes account of the underlying dynamics of disease transmission and balance state-level pre-intervention characteristics. We prove that our estimator provides causal intervention effect under assumptions. We apply this method to analyze US COVID-19 incidence cases to estimate the effects of six interventions. We show that lockdown has the largest effect on reducing transmission and reopening bars significantly increase transmission. States with a higher percentage of non-White population are at greater risk of increased R t $$ {R}_t $$ associated with reopening bars.

Optimizing relapse prevention and changing habits (REACH+) in anorexia nervosa.

INTRODUCTION: Relapse rates in anorexia nervosa (AN) are high, even after full weight restoration. This study aims to develop a relapse prevention treatment that specifically addresses persistent maladaptive behaviors (habits). Relapse Prevention and Changing Habits (REACH+) aims to support patients in developing routines that promote weight maintenance, encourage health, and challenge habits that perpetuate illness. The clinical trial design uses the Multiphase Optimization STrategy (MOST) framework to efficiently identify which components of treatment contribute to positive outcomes. METHODS: Participants will be 60 adults with AN who have achieved weight restoration in an inpatient setting. Treatment will consist of 6 months of outpatient telehealth sessions. REACH+ consists of behavior, cognitive, and motivation components, as well as food monitoring and a skill consolidation phase. A specialized online platform extends therapy between sessions. Participants will be randomly assigned to different versions of each component in a fractional factorial design. Outcomes will focus on maintenance of remission, measured by rate of weight loss and end-of-trial status. Interventions that contribute to remission will be included in an optimized treatment package, suitable for a large-scale clinical trial of relapse prevention in AN.

The RAISE Connection Program for Early Psychosis: Secondary Outcomes and Mediators and Moderators of Improvement.

The aims of this study were to explore secondary outcomes of a coordinated specialty care program for persons with early psychosis, including quality of life and recovery, as well as to explore mediators and moderators of improvement in occupational and social functioning and symptoms. Sixty-five individuals across two sites were enrolled and received services for up to 2 years. Trajectories for individuals' outcomes over time were examined using linear and quadratic mixed-effects models with repeated measures. In addition, baseline prognostic factors of participant improvement in social and occupational functioning were explored based on previous literature and expert opinion of the analytic team. Results demonstrate that the program was effective in improving quality of life and recovery over time. Furthermore, processing speed was identified as a significant moderator of improvement in occupational Global Assessment of Function, and treatment fidelity, engagement, and family involvement were identified as mediators of improvement in social and occupational functioning.

Implementing Coordinated Specialty Care for Early Psychosis: The RAISE Connection Program.

OBJECTIVE: The RAISE (Recovery After an Initial Schizophrenia Episode) Connection Program Implementation and Evaluation Study developed tools necessary to implement and disseminate an innovative team-based intervention designed to promote engagement and treatment participation, foster recovery, and minimize disability among individuals experiencing early psychosis. This article describes the treatment model and reports on service utilization and outcomes. It was hypothesized that individuals' symptoms and functioning would improve over time. METHODS: A total of 65 individuals in RAISE Connection Program treatment across two sites (Baltimore and New York City) were enrolled and received services for up to two years. Primary outcomes, including social and occupational functioning and symptoms, were evaluated. Trajectories for individuals' outcomes over time were examined with linear and quadratic mixed-effects models with repeated measures. RESULTS: Measures of occupational and social functioning improved significantly over time, symptoms declined, and rates of remission improved. Visits were most frequent during the first three months, with a mean±SD of 23.2±11.5 unduplicated staff encounters per quarter. Such encounters decreased to 8.8±5.2 in the final quarter of year 2. CONCLUSIONS: The overall project was successful in that the treatment program was delivered and tools useful to other clinical settings were produced. The strengths of this study lie in the demonstrated feasibility of delivering the coordinated specialty care model and the associated high rates of engagement among individuals who are typically difficult to engage in treatment. Notwithstanding the lack of a built-in comparison group, participant outcomes were promising, with improvements comparable to those seen with other successful interventions.

Treatment of complicated grief in elderly persons: a randomized clinical trial.

IMPORTANCE: Complicated grief (CG) is a debilitating condition, most prevalent in elderly persons. However, to our knowledge, no full-scale randomized clinical trial has studied CG in this population. OBJECTIVE: To determine whether complicated grief treatment (CGT) produces greater improvement in CG and depressive symptoms than grief-focused interpersonal psychotherapy (IPT). DESIGN, SETTING, AND PARTICIPANTS: Randomized clinical trial enrolling 151 individuals 50 years or older (mean [SD] age, 66.1 [8.9] years) scoring at least 30 on the Inventory of Complicated Grief (ICG). Participants were recruited from the New York metropolitan area from August 20, 2008, through January 7, 2013, and randomized to receive CGT or IPT. The main outcome was assessed at 20 weeks after baseline, with interim measures collected at 8, 12, and 16 weeks after baseline. INTERVENTIONS: Sixteen sessions of CGT (n = 74) or IPT (n = 77) delivered approximately weekly. MAIN OUTCOMES AND MEASURES: Rate of treatment response, defined as a rating from an independent evaluator of much or very much improved on the Improvement subscale of the Clinical Global Impression Scale. RESULTS: Both treatments produced improvement in CG symptoms. Response rate for CGT (52 individuals [70.5%]) was more than twice that for IPT (24 [32.0%]) (relative risk, 2.20 [95% CI, 1.51-3.22]; P < .001), with the number needed to treat at 2.56. Secondary analyses of CG severity and CG symptom and impairment questionnaire measures confirmed that CGT conferred a significantly greater change in illness severity (22 individuals [35.2%] in the CGT group vs 41 [64.1%] in the IPT group were still at least moderately ill [P = .001]), rate of CG symptom reduction (1.05 ICG points per week for CGT vs 0.75 points per week for IPT [t633 = 3.85; P < .001]), and the rate of improvement in CG impairment (0.63 work and Social Adjustment Scale points per week with CGT and 0.39 points per week with IPT [t503 = 2.87; P = .004]). Results were not moderated by participant age. CONCLUSIONS AND RELEVANCE: Complicated grief treatment produced clinically and statistically significantly greater response rates for CG symptoms than a proven efficacious treatment for depression (IPT). Results strongly support the need for physicians and other health care providers to distinguish CG from depression. Given the growing elderly population, the high prevalence of bereavement in aging individuals, and the marked physical and psychological impact of CG, clinicians need to know how to treat CG in older adults.
