RESUMO
BACKGROUND: Cerebral malaria is one of the most severe complications attributed to protozoal infection by Plasmodium falciparum, gaining prominence in children mortality rates in endemic areas. This condition has a complex pathogenesis associated with behavioral, cognitive and motor sequels in humans and current antimalarial therapies have shown little effect in those aspects. Natural products with antioxidant and anti-inflammatory properties have become a valuable alternative therapeutic option in the treatment of distinct conditions. In this context, this study investigated the neuroprotective effect of Euterpe oleracea (açai) enriched diet during the development of experimental cerebral malaria induced by the inoculation of Swiss albino mice with Plasmodium berghei ANKA strain. METHODS: After Plasmodium infection, animals were maintained on a feeding with Euterpe oleracea enriched ration and parameters such as survival curve, parasitemia and body weight were routinely monitored. The present study has also evaluated the effect of açai-enriched diet on the blood-brain barrier leakage, histological alterations and neurocognitive impairments in mice developing cerebral malaria. RESULTS: Our results demonstrate that between 7th-19th day post infection the survival rate of the group treated with açai enriched ration was higher when compared with Plasmodium-infected mice in which 100% of mice died until the 11th days post-infection, demonstrating that açai diet has a protective effect on the survival of infected treated animals. The same was observed in the brain vascular extravasation, where Evans blue dye assays showed significantly less dye extravasation in the brains of Plasmodium-infected mice treated with açai enriched ration, demonstrating more preserved blood-brain barrier integrity. Açai-enriched diet also attenuate the histopathological alterations elicited by Plasmodium berghei infection. We also showed a decrease of the neurological impairments arising from the exposure of cerebral parenchyma in the group treated with açai diet, ameliorating motor and neuropsychiatric changes, analyzed through the SHIRPA protocol. CONCLUSION: With these results, we conclude that the treatment with açai enriched ration decreased the mortality of infected animals, as well as protected the blood-brain barrier and the neurocognitive deficits in Plasmodium-infected animals.

School based health centers (SBHCs) are often at the front line of medical and mental health services for students in the schools they serve. Citywide school closures in New York City in March 2020 and ongoing social distancing procedures resulted in significant changes in SBHC services as well as access to these services. Furthermore, the combination of COVID-19 related stressors and the increased likelihood of adverse childhood events experienced by urban youth creates conditions for the exacerbation of mental health concerns among youth in metropolitan areas. The following article will explore the role of SBHCs as community agents focused on prevention and reduction of mental health concerns prior and during the current pandemic, as well as existing health disparities experienced by urban youth populations. The authors will also discuss research examining mental health concerns already present in global populations affected by COVID-19 as it may foreshadow the challenges to be faced by U.S. urban youth. Lastly, the authors describe recommendations, practice implications, and opportunities for preventative strategies and therapeutic interventions in school based health settings.

Despite significant progress in research on the treatment and prevention of psychological, behavioral, and health problems, the translation of this knowledge into population-wide benefit remains limited. This paper reviews the state of America's children and families, highlighting the influence of stressful contextual and social conditions on child and family well-being and the concentration of disadvantage in numerous neighborhoods and communities throughout the nation. It then briefly reviews the progress that has been made in pinpointing policies that can reduce stressful contextual conditions such as poverty, discrimination, and the marketing of unhealthful foods and substances. It also describes numerous family and school interventions that have proven benefit in preventing psychological and behavioral problems as diverse as tobacco, alcohol, and other drug use; depression; antisocial behavior; academic failure; obesity prevention; and early childbearing. We argue that progress in translating existing knowledge into widespread benefit will require a nationwide effort to intervene comprehensively in neighborhoods and communities of concentrated disadvantage. We present a strategic plan for how such an effort could be organized. The first step in this organizing would be the creation of a broad and diverse coalition of organizations concerned with advancing public health and well-being. Such a coalition could increase public support both for the policies needed to focus on these disadvantaged areas and the research needed to incrementally improve our ability to help these areas.

Glufosinate ammonium (GLA) is a widely used organophosphate herbicide, which could be commonly detected in body fluids of both pregnant women and newborns. Existing evidences indicate that GLA has reproductive toxicity, while data concerning the effects of prenatal GLA exposure on neurodevelopment is rather limited. Here we employed a mouse model exposed to GLA prenatally. Reduced locomotor activity, impaired memory formation and autism-like behaviors were observed in the treatment group. Marked alteration in gut microbiome of the treatment offspring mice could be found at 4th week, and seemed to recover over time. Fecal metabolomics analysis indicated remarkable changes in microbiome-related metabolism in the treatment group, which could be the cause of behavioral abnormality in mice. Present study suggested that prenatal exposure to GLA disturbed gut microbiome and metabolism, and thereby induced behavioral abnormalities in mice.

Physical exercise has proven to be beneficial to mitigate several deleterious effects associated with neurodegenerative diseases, including Alzheimer's Disease (AD). Here, we investigated the role of long-term exercise as a preventive and therapeutic tool against AD cognitive and behavioral impairments using a sporadic AD-like rat model, established through the administration of streptozotocin (STZ) inside both cerebral ventricles (icv). Six-weeks-old Wistar male rats (56) were divided into groups (either saline or STZ): sedentary (Sed), voluntary physical activity (VPA), VPAâ¯+â¯endurance treadmill training (VPAâ¯+â¯ET) and VPAâ¯+â¯ET only after the injection (VPAâ¯+â¯ET-post). Surgeries occurred at 16wks and the animals were sacrificed at 28 wks. VPA, VPAâ¯+â¯ET, and VPAâ¯+â¯ET-post had continuous access to the running wheels during the entire experimental protocol. VPAâ¯+â¯ET (entire protocol) and VPAâ¯+â¯ET-post (only after surgical procedure) ran 60â¯min/d, 25â¯m/min, 5d/wk in a treadmill. Both ET regimens led to significant improvements in the compromised spatial learning and long-term memory of STZ-infused animals that were not observed neither in the saline Sed nor in VPA STZ groups. General activity patterns and exploration habits were also ameliorated with chronic-exercise in STZ treated animals, while freezing patterns were decreased in these groups. these results were further. Positive alterations were seen in mitochondrial oxygen consumption endpoints (synaptosomal and non-synaptosomal brain mitochondria) that might underlie the neurobehavioral improvements observed. Data suggest that VPA alone was not able to counteract the AD-related deleterious consequences, although when accompanied by endurance training (either lifelong or later-life) may be able to prevent and reverse cognitive and phenotypic impairments associated with AD.

INTRODUCTION: The purpose of this study was to examine mental health status by gender identity among undergraduate and graduate students. METHODS: Data came from the 2015-2017 Healthy Minds Study, a mobile survey of randomly selected students (N=65,213 at 71 U.S. campuses, including 1,237 gender minority [GM] students); data were analyzed in 2018. Outcomes were symptoms of depression, anxiety, eating disorders, self-injury, and suicidality based on widely used, clinically validated screening instruments. Bivariable and multivariable analyses explored differences between GM and cisgender (non-GM) students as well as by assigned sex at birth. RESULTS: Across mental health measures, a significantly higher prevalence of symptoms was observed in GM students than cisgender students. Compared with 45% of cisgender students, 78% of GM students met the criteria for 1 or more of the aforementioned mental health outcomes. GM status was associated with 4.3 times higher odds of having at least 1 mental health problem (95% CI=3.61, 5.12). CONCLUSIONS: Findings from this largest campus-based study of its kind using representative data with both gender identity and mental health measures underscore the importance of recognizing and addressing GM mental health burdens, such as by screening for mental health and providing gender-affirming services. There is broad urgency to identify protective factors and reduce mental health inequities for this vulnerable population.

OBJECTIVES: Our objective was to determine whether family caregivers of people with dementia (PwD) are willing to pay for an in-home intervention that provides strategies to manage behavioral symptoms and caregiver stress and to identify predictors of willingness-to-pay (WTP). METHODS: During baseline interviews of a randomized trial and before treatment assignment, caregivers were asked how much they were willing to pay per session for an eight-session program over 3 months. We stratified the sample into those who refused to provide a WTP, those willing to pay $US0, and those willing to pay > $US0. We used a two-part model, controlling for demographic characteristics, to predict adjusted mean WTP and to examine associations between WTP, clinical features (cognition, function, behavioral symptoms), and time spent assisting PwD with daily activities. First, we used logistic regression to model the probability a caregiver was willing to pay > $US0. Second, we used a generalized linear model (log link and Gamma distribution) to estimate the amount caregivers were willing to pay conditional on WTP > $US0. RESULTS: Of 250 dyads enrolled, 226 (90%) had complete data and were included in our analyses. Of 226 dyads, 26 (11%) refused to provide a WTP value, 72 (32%) were willing to pay $US0, and 128 (57%) were willing to pay > $US0. In the combined model, mean adjusted WTP was $US36.00 (95% confidence interval [CI] 26.72-45.27) per session. Clinical features were not significantly associated with WTP. One additional hour providing PwD assistance was associated with a $US1.64 (95% CI 0.23-3.04) increase in WTP per session. CONCLUSION: As caregivers spend more time assisting with daily activities, they are willing to pay more for a supportive program. CLINICAL TRIAL REGISTRATION NUMBER: NCT01892579.

BACKGROUND: Restricted and Repetitive Behaviours (RRBs) are some of the most difficult behaviours to manage in children with Autism Spectrum Disorders (ASD). Although RRBs frequently occur in educational settings, we know little about the way in which teachers understand these behaviours. AIMS: The study aimed to explore the attributions, emotional response and feelings of confidence held by teachers working in different educational settings when faced with RRBs. METHODS AND PROCEDURES: A single group survey design using behavioural vignettes was adopted in order to elicit teacher beliefs and ratings. OUTCOMES AND RESULTS: Analysis indicated that there were differences in the attributions and confidence ratings held for different types of RRBs. Significant differences were also observed between teachers working in mainstream and specialist educational settings. Emotional response and confidence scores were often predictive of one another alongside factors related to teaching experience. CONCLUSION AND IMPLICATIONS: The findings indicate that teachers from mainstream schools potentially hold less helpful beliefs in response to RRBs and therefore are a professional group who may benefit the most from additional support and training. Further research could consider conducting a qualitative exploration of why teachers hold certain beliefs about RRBs and/or sampling those who are less experienced in working with children with ASD.

BACKGROUND: A high anticholinergic burden (AB) is associated with the occurrence of behavioral and psychological symptoms (BPSDs), which are frequent in dementia. OBJECTIVES: Our aim was to determine the threshold for a reduction in AB that would lead to a clinically significant improvement in BPSDs (in terms of frequency, severity, and disruptiveness). DESIGN: A single-center prospective study. SETTINGS: Dedicated geriatric care unit specializing in the management of patients with dementia. PARTICIPANTS: The study involved older patients with dementia, hospitalized for management of BPSDs. METHODS: One hundred forty-seven patients were included (mean age = 84.1 ± 5.2 years). The AB was assessed using 3 scales, namely, the Anticholinergic Drug Scale (ADS), the Anticholinergic Cognitive Burden scale (ACB), and the Anticholinergic Risk Scale (ARS). A clinically significant improvement in BPSDs was defined as a reduction of 4 points in the frequency × severity (F×S) score of the Neuropsychiatric Inventory-Nursing Home (NPI-NH) questionnaire. The threshold for a reduction in AB that corresponded to a clinically significant improvement in BPSDs was determined by multiple linear regression. RESULTS: One hundred forty-seven patients were included (mean age = 84.1 ± 5.2 years). Using the ADS, a reduction of 2 points in AB in patients with moderate-intensity BPSDs was associated with a clinically significant improvement in the F×S score of the NPI-NH [6.34, 95% confidence interval (CI) 4.54-8.14], and a reduction of 3 points was associated with a clinically significant improvement in the occupational disruptiveness score (4.26, 95% CI 3.11-5.41). CONCLUSIONS/IMPLICATIONS: In older patients with dementia presenting BPSDs, the risk-benefit ratio of anticholinergic drugs is debatable and, where possible, drugs with a lower AB would be preferable. Because BPSDs are a frequent cause of hospitalization, a standardized approach to analysis and reduction of AB is warranted in this population. Depending on the scale used to assess anticholinergic burden (AB), a small reduction in AB is associated with a decrease in frequency, severity, and disruptiveness of moderate-intensity BPSDs. Drugs with a high AB should be avoided where possible in older patients with dementia, and drugs with a lower AB would be preferable. Heterogeneity between the assessment scales for AB precludes generalization of the impact of a reduction in AB on BPSDs.

PURPOSE: Living with end-stage renal disease may be burdensome, not only for patients, but also for caregivers. In this study, we aim to compare caregiver burden, psychological symptoms in caregivers of peritoneal dialysis (PD), hemodialysis (HD), and transplantation (TX), and find out associated factors. METHODS: A total of 43 PD, 42 HD, 42 TX patients and a total of 127 caregivers that were actively involved with the care of their patients' dialysis were enrolled. Patients had been on renal replacement therapy at least for 6 months and caregivers had given care at least for 6 months. The World Health Organization Quality of Life short version and hospital anxiety and depression scale (HAD) were applied to the patients. Symptom Checklist-90-Revised and Zarit caregiver burden scale were applied to the caregivers. RESULTS: Zarit caregiver burden score was found highest in HD group, which was significantly higher than PD and TX. All three groups had similar HAD anxiety scores, whereas the HAD depression score was highest in HD group, lower in PD, and lowest in TX. Quality of life was lowest in HD group. Zarit caregiver burden score was found higher in caregivers with symptoms like somatization, anxiety, obsessive-compulsive, depression, interpersonal sensitivity, psychoticism, paranoid ideation, hostility, and additional psychological symptoms than the ones who did not have these symptoms. Psychological symptoms were similar in PD, HD, and TX groups. CONCLUSION: Caregiver burden was found highest in HD group. Educational, social, and psychological support interventions may be considered for caregivers.

A growing body of research examining biological factors associated with suicidal behaviors highlights the role of brain-derived neurotropic factor (BDNF), involved in neurogenesis and synaptic plasticity. There is evidence suggesting that suicide attempters have lower BDNF levels than those with no history of suicide attempts. The key question addressed in the current investigation is whether differences in circulating BDNF levels persist beyond the current suicidal episode and would be observed in those with a past history of suicide attempts (SA). Plasma levels of BDNF were assessed in 73 women from the community. We found that women with a history of SA exhibited lower levels of BDNF than women with no SA history and this difference was maintained after statistically controlling for the influence of other potential psychiatric or demographic factors. These findings support and extend existing research by suggesting that circulating BDNF levels are decreased among individuals with a history of SA compared to individuals with no history of SA. This relation appeared to be specific to women's history of SA and was not explained by other potential psychiatric or demographic factors, which further highlights the role of BDNF as a promising biomarker for suicidal behavior.

PURPOSE: To explore the feasibility of implementing the Tailored Activity Program with a cohort of people with frontotemporal dementia and their carers (dyads). METHODS: The Tailored Activity Program is an occupational therapy based intervention that involves working collaboratively with family carers and prescribes personalized activities for behavioral management in people with dementia. Twenty dyads randomized into the study (Tailored Activity Program: n = 9; Control: n = 11) were assessed at baseline and 4-months. Qualitative analyzes evaluated feasibility and acceptability of the program for the frontotemporal dementia cohort, and quantitative analyzes (linear mixed model analyzes, Spearman's rho correlations) measured the impact of the program on the dyads. RESULTS: The Tailored Activity Program was an acceptable intervention for the frontotemporal dementia dyads. Qualitative analyses identified five themes: "carer perceived benefits", "carer readiness to change", "strategies used by carer to engage person with dementia", "barriers to the Tailored Activity Program uptake/implementation", and "person with dementia engagement". Quantitative outcomes showed an overall reduction of behavioral symptoms (F18.34 = 8.073, p = 0.011) and maintenance of functional performance in the person with dementia (F18.03 = 0.375, p = 0.548). CONCLUSIONS: This study demonstrates the potential for using an activity-based intervention such as the Tailored Activity Program in frontotemporal dementia. Service providers should recognize that while people with frontotemporal dementia present with challenging issues, tailored therapies may support their function and reduce their behavioral symptoms. Implications for rehabilitation The Tailored Activity Program is an occupational therapy based intervention that involves prescribing personalized activities for behavioral management in dementia. The Tailored Activity Program is an acceptable and feasible intervention approach to address some of the unique behavioral and functional impairments inherent in frontotemporal dementia.

GABAergic (Gamma-aminobutyric acid) and neurotrophic derangements have important implication in schizophrenia, a neuropsychiatric disease. Previous studies have shown that nicotinamide adenine dinucleotide phosphate oxidase (NADPH-oxidase) alters GABAergic and neurotrophic activities via inflammatory and oxidative pathways. Thus, it has been proposed that agents with anti-oxidant and anti-inflammatory properties might be beneficial for the treatment of the disease. Morin is neuroactive bioflavonoid compound, which has been reported to demonstrate antipsychotic and anti-oxidant/anti-inflammatory activities. In this study, we further evaluated its effects on the brain markers of GABAergic, neurotrophic and oxidative alterations in the preventive and reversal of schizophrenia-like behavior induced by ketamine (KET). In the prevention protocol, adult mice were treated intraperitoneally with morin (100â¯mg/kg/day), haloperidol (1â¯mg/kg/day), risperidone (0.5â¯mg/kg/day), or saline (10â¯mL/kg/day) for 14 consecutive days. In addition, the animals were administered KET (20â¯mg/kg/day) from the 8th to the 14th day. In the reversal protocol, the animals received KET or saline for 14â¯days. From 8th to 14th days mice were additionally treated with morin, haloperidol, risperidone or saline. Schizophrenic-like behaviors consisting of positive (stereotypy test), negative (behavioral despair in forced swim test) and cognitive (novel-object recognition test) symptoms were evaluated. Afterwards, brain levels of biomarkers of GABAergic (Glutamic acid decarboxylase-67, GAD67), neurotrophic (Brain-derived neurotrophic factor, BDNF) and oxidative [NADPH-oxidase, superoxide dismutase, (SOD) and catalase (CAT)] alterations were determined in the striatum, prefrontal cortex (PFC) and hippocampus, respectively. Morin significantly (pâ¯<â¯0.05) prevented and reversed KET-induced increased stereotypy, behavioral despair and deficit in cognitive functions when compared with KET-treated mice respectively. Also, morin and risperidone but not haloperidol, significantly (pâ¯<â¯0.05) prevented and reversed the decreases in expressions of GAD67 and BDNF immunoreactivity in the striatum, PFC and hippocampus caused by KET. Moreover, morin and risperidone significantly (pâ¯<â¯0.05) decreased regional brain expressions of NADPH-oxidase immunopositive cells and increased endogenous anti-oxidant enzymes (SOD and CAT) in the striatum, PFC and hippocampus relative to KET controls respectively. Taken together, these findings further suggest that the antipsychotic-like activity of morin may be mediated via mechanisms related to enhancement of GABAergic neurotransmission and neurotrophic factor, and suppression of NADPH-oxidase induced oxidative damage in mice.

PURPOSE: This study evaluated the longitudinal influence of an individualized evidence-based psychoeducational intervention for caregivers on frequency of behavioral symptoms in persons with dementia (PWD) and caregiver reaction to these symptoms. The intervention included information about the disease process using Progressively Lowered Stress Threshold (PLST) content and a family meeting based on Mittelman's New York University Intervention. METHOD: A quasi-experimental study design was implemented. The Revised Memory and Behavior Problems Checklist was administered to N = 127 caregiver/care recipient dyads at baseline, 6, 12, and 18 months follow-up. All caregivers were enrolled in the intervention at baseline and followed over 18 months. Linear mixed models were developed to evaluate effects on frequency of behavioral symptoms in PWD and caregiver response. RESULTS: The most frequently occurring behavior was memory problems, although depressive behaviors produced the most negative caregiver responses. Between baseline and 6-month follow-up, there was a significant decrease in frequency of behavioral symptoms. Overall, there was a significant decrease in caregiver's reaction to behavioral symptoms from baseline to 18-month follow-up.

OBJECTIVE: Prevention of child behavior problems may reduce later mental health problems. We compared the effectiveness, at the population level, of an efficacious targeted prevention program alone or following a universal parenting program. METHODS: Three-arm, cluster randomized controlled trial. One thousand three hundred fifty-three primary caregivers and healthy 8-month-old babies recruited from July 2010 to January 2011 from well-child centers (randomization unit). PRIMARY OUTCOME: Child Behavior Checklist (CBCL) externalizing and internalizing scales* at child ages 3 and 4.5 years. SECONDARY OUTCOMES: Parenting Behavior Checklist* and over-involved/protective parenting (primary caregiver report). Secondary caregivers completed starred measures at age 3. RESULTS: Retention was 76% and 77% at ages 3 and 4.5 years, respectively. At 3 years, intention-to-treat analyses found no statistically significant differences (adjusted mean difference [95% confidence interval (CI); p-value]) for externalizing (targeted vs usual care -0.2 [-1.7 to 1.2; p = .76]; combined vs usual care 0.4 [-1.1 to 1.9; p = .60]) or internalizing behavior problems (targeted vs usual care 0.2 [-1.2 to 1.6; p = .76]; combined vs usual care 0.4 [-1.1 to 2.0; p = .58]). Primary outcomes were similar at 4.5 years. At 3 years, primary and secondary caregivers reported less over-involved/protective parenting in both the combined and targeted versus usual care arm; secondary caregivers also reported less harsh discipline in the combined and targeted versus usual care arm. Mean program costs per family were A$218 (targeted arm) and A$682 (combined arm). CONCLUSION: When translated to the population level by existing staff, pre-existing programs seemed ineffective in improving child behavior, alone or in combination, but improved parenting.

OBJECTIVE: The aim of this study was to evaluate the impact of a reduction of the anticholinergic burden (AB) on the frequency and severity of behavioral and psychological symptoms of dementia (BPSD) and their repercussions on the care team (occupational disruptiveness). METHODS: In this prospective, single-center study in an acute care unit for Alzheimer disease (AD) and related disorders, 125 elderly subjects (mean age: 84.4 years) with dementia presented with BPSD. The reduction of the AB was evaluated by the Anticholinergic Cognitive Burden Scale. BPSD were evaluated with the Neuropsychiatric Inventory-Nursing Home Version (NPI-NH). The effect of the reduction of the AB on the BPSD was studied using logistic regression adjusting for the variables of the comprehensive geriatric assessment. RESULTS: Seventy-one subjects (56.8%) presenting with probable AD, 32 (25.6%) mixed dementia (AD and vascular), 17 (13.6%) vascular dementia, and 5 (4.0%) Lewy body dementia were included. Reducing the AB by at least 20% enabled a significant decrease in the frequency × severity scores of the NPI-NH (adjusted odds ratio: 3.5; 95% confidence interval: 1.6-7.9) and of the occupational disruptiveness score (adjusted odds ratio: 9.9; 95% confidence interval: 3.6-27.3). CONCLUSION: AB reduction in elderly subjects with dementia makes is possible to reduce BPSD and caregiver burden. Recourse to treatments involving an AB must be avoided as much as possible in these patients, and preferential use of nonpharmacologic treatment management plans is encouraged.

OBJECTIVE: To determine whether a population-delivered parenting programme assists in preventing internalising problems at school entry for preschool children at-risk with temperamental inhibition. METHODS: Design: a randomised controlled trial was used. SETTING: the setting was 307 preschool services across eight socioeconomically diverse government areas in Melbourne, Australia. PARTICIPANTS: a total of 545 parents of inhibited 4-year-old children: 498 retained at 1-year follow up. Early intervention: Cool Little Kids parenting group programme was implemented. Primary outcomes: the primary outcomes were child DSM-IV anxiety disorders (assessor blind) and internalising problems. SECONDARY OUTCOMES: the secondary outcomes were parenting practices and parent mental health. RESULTS: At 1-year follow up (mean (standard deviation) age = 5.8 (0.4) years), there was little difference in anxiety disorders between the intervention and control arms (44.2% vs 50.2%; adjusted odds ratio = 0.86, 95% confidence interval = [0.60, 1.25], p = 0.427). Internalising problems were reduced in the intervention arm (Strengths and Difficulties Questionnaire: abnormal - 24.2% vs 33.0%; adjusted odds ratio = 0.56, 95% confidence interval = [0.35, 0.89], p = 0.014; symptoms - mean (standard deviation) = 2.5 (2.0) vs 2.9 (2.2); adjusted mean difference = -0.47, 95% confidence interval = [-0.81, -0.13], p = 0.006). Parents' participation in the intervention was modest (29.4% attended most groups, 20.5% used skills most of the time during the year). A priori interaction tests suggested that for children with anxious parents, the intervention reduced anxiety disorders and internalising symptoms after 1 year. CONCLUSION: Offering Cool Little Kids across the population for inhibited preschoolers does not impact population outcomes after 1 year. Effects may be emerging for inhibited children at highest risk with parent anxiety. Trial outcomes will continue into mid-childhood.

Nonpharmacological approaches for managing behavioral symptoms of dementia remain widely underutilized, due in part to near-universal training needs reported by dementia caregivers in recent research. This article examines the development, core components, and initial outcomes of an evidence-informed, competency-based training program in the prevention and management of behavioral symptoms of dementia among care managers and nurses within an aging services system. The Vital Outcomes Inspired by Caregiver Engagement (VOICE) Dementia Care Training Program was developed based on identification of state-of-the-art approaches to managing behaviors through expert review of the literature and structured needs assessment. Results reveal robust improvements in knowledge, attitudes, and self-efficacy among training participants, with largest effect sizes (d = 1.8) on domains of knowledge and self-efficacy to manage behaviors. Findings support the feasibility and effectiveness of training in improving the abilities and confidence of aging services providers in dementia care and, specifically, in the nonpharmacological management of dementia-related behaviors.

OBJECTIVE: This study aims to test an evidence-based parenting program offered in churches among Filipino-American parents and estimate effect size for a fully powered trial. METHODS: Twenty-two parents of children aged 6 to 12 years were randomly assigned to either an intervention or a waiting-list control group. Parents' perceptions of child behavior, parenting practices, and parenting stress were obtained at baseline. Parents in the experimental group attended The Incredible Years School Age Program, which consisted of 12 weekly 2-hour sessions. A follow-up assessment was performed after the intervention and 12 weeks later. The intervention was subsequently repeated with the control group. Satisfaction was assessed with a 40-item measure. Analysis of covariance was used to compare the intervention group postintervention versus the control group. Paired t-tests compared mean parenting practices, parenting stress, and child behavior outcomes. Satisfaction was assessed descriptively. RESULTS: Twenty-two parents completed all assessments and the intervention. Analysis of variance comparing intervention and control groups with repeated measures (pre- and post-test measures) revealed that the program has a positive impact on parenting stress, parenting practices (physical punishment, positive verbal discipline), and parent's perception of their child's behavior (internalizing symptoms, externalizing symptoms, and number of problematic behaviors). Analyses of all participants comparing pre- and post intervention revealed improvements in parenting stress, positive verbal discipline, and child externalizing and total problem behaviors. Families reported high satisfaction with the content and format of the intervention. CONCLUSION: Results support the feasibility of providing an evidence-based parenting program to Filipino parents in churches to prevent future behavioral health problems.
