Translating motivational interviewing for the HPV vaccine into a computable ontology model for automated AI conversational interaction.

Human papillomavirus (HPV) vaccinations are lower than expected. To protect the onset of head and neck cancers, innovative strategies to improve the rates are needed. Artificial intelligence may offer some solutions, specifically conversational agents to perform counseling methods. We present our efforts in developing a dialogue model for automating motivational interviewing (MI) to encourage HPV vaccination. We developed a formalized dialogue model for MI using an existing ontology-based framework to manifest a computable representation using OWL2. New utterance classifications were identified along with the ontology that encodes the dialogue model. Our work is available on GitHub under the GPL v.3. We discuss how an ontology-based model of MI can help standardize/formalize MI counseling for HPV vaccine uptake. Our future steps will involve assessing MI fidelity of the ontology model, operationalization, and testing the dialogue model in a simulation with live participants.

A microcosting approach for planning and implementing community-based mental health prevention program: what does it cost?

BACKGROUND: Estimating program costs when planning community-based mental health programs can be burdensome. Our aim was to retrospectively document the cost for the first year of planning and implementing Healthy Minds Healthy Communities (HMHC), a mental health promotion and prevention multi-level intervention initiative. This Program is among the first to use the Community Initiated Care (CIC) model in the US and is aimed at building community resilience and the capacity for communities to provide mental health support, particularly among those disproportionately impacted by COVID-19. Our objective is to share our methods for costing a program targeting 10 zip codes that are ethnically and linguistically diverse and provide an example for estimating the cost of a mental health prevention and promotion programs consisting of multiple evidence-based interventions. METHODS: We used a semi-structured interview process to collect cost data through the first year of program planning, start-up and initial implementation from key staff. We calculated costs for each activity, grouped them by major project categories, and identified the cost drivers of each category. We further validated cost estimates through extensive literature review. The cost analysis was done from the provider's perspective, which included the implementing agency and its community partners. We delineated costs that were in-kind contributions to the program by other agency, and community partners. Sensitivity analyses were conducted to estimate uncertainty around parameters. RESULTS: For the first year of the development and implementation of the program, (funded through program and in-kind) is estimated at $1,382,669 (2022 US$). The costs for the three main activity domains for this project are: project management $135,822, community engagement $364,216 and design and execution $756,934. Overall, the cost drivers for the first year of this intervention were: hiring and onboarding staff, in-person community building/learning sessions, communications and marketing, and intervention delivery. CONCLUSION: Implementation of community-based mental health promotion and prevention programs, when utilizing a participatory approach, requires a significant amount of upfront investment in program planning and development. A large proportion of this investment tends to be human capital input. Developing partnerships is a successful strategy for defraying costs.

Pilot Implementation of a Nutrition-Focused Community-Health-Worker Intervention among Formerly Chronically Homeless Adults in Permanent Supportive Housing.

Food insecurity is a known health equity threat for formerly chronically homeless populations even after they transition into permanent housing. This project utilized a human-centered design methodology to plan and implement a nutrition-focused community-health-worker (CHW) intervention in permanent supportive housing (PSH). The project aimed to increase access to healthy foods, improve nutritional literacy, healthy cooking/eating practices, and build community/social connectedness among 140 PSH residents. Validated food-security screening conducted by CHWs identified low or very low food security among 64% of 83 residents who completed the baseline survey, which is similar to rates found in a previous study among formerly homeless populations placed in PSH. Major themes identified through an analysis of resident feedback include (1) lack of needed kitchenware/appliances for food preparation, (2) knowledge gaps on how to purchase and prepare healthier food, (3) positive perceptions of healthy food options, (4) expanded preferences for healthy, easy-to-prepare foods, (5) regaining cooking skills lost during homelessness, (6) positive experiences participating in group activities, (7) community re-entry, and (8) resident ownership. Preliminary findings suggest the use of a human-centered design methodology for planning and implementing this multi-level CHW intervention helped reduce food insecurity, engaged participants in learning and adopting healthy and safe cooking and eating practices, and fostered social connectedness and feelings of community among formerly chronically homeless PSH residents.

The Association between Potentially Traumatic Events and Cocaine, Cannabis, and Alcohol Use Differs by Race.

Background: Although exposure to potentially traumatic events (PTEs) for Black and Latinx may be comparable or lower than their White counterparts, type of trauma experiences differ such as more interpersonal trauma and violence reported by Black people, who also experience higher rates of PTSD. In this retrospective study, we examined the association between use of particular substances and various PTEs and the race/ethnicity-group differences for this association. Methods: One-hundred seventy-nine participants recruited from an outpatient substance use disorder program from February 2018 to October 2020 completed measures on lifetime trauma history and current/past cocaine, cannabis, and alcohol misuse. Bayesian generalized linear modeling with horseshoe prior was used to predict substance misuse using 17 PTEs, then PTEs were ranked and examined by racial/ethnic group. Results: No PTEs were associated with substance misuse across all four r/e groups. Transportation accident, natural disaster, war exposure, and other stressful events were associated with substance misuse across two or three r/e groups. Notably, the three PTEs involving interpersonal violence in our study (weapon assault, physical assault, and sexual assault) were only associated with substance misuse (posterior probability ≥70%) for Latinx participants. Conclusion: The relational nature of interpersonal/violent traumas may make them particularly salient for Latinx people where interpersonal relationships are prioritized. These types of traumas may also be viewed as an extension of discrimination and exclusion, two longstanding, intractable issues for people of color in the US, making them even more damaging. Furthermore, lack of resources may limit options for coping, resulting in substance use problems.

Predictors of self-reported general health status in people experiencing homelessness with serious mental illness.

PURPOSE: The growing homeless population in the U.S.A. is disproportionately impacted by poor mental and physical health status, including a higher incidence of acute and chronic health problems, increased hospitalizations, and premature mortality compared to the general population. This study examined the association between demographic, social, and clinical factors and perceptions of general health status among the homeless population during admission to an integrated behavioral health treatment program. METHODS: The study sample included 331 adults experiencing homelessness with a serious mental illness or co-occurring disorder. Participants were enrolled in services at a day program for unsheltered homeless adults, a residential substance use treatment program for males experiencing homelessness, a psychiatric step-down respite program for those experiencing homelessness following psychiatric hospitalization, permanent supportive housing for formerly chronically homeless adults, a faith-based food distribution program, and homeless encampment sites in a large urban area. Participants were interviewed using The Substance Abuse and Mental Health Services Administration's National Outcome Measures tool and a validated health-related quality of life measurement tool, SF-36. Data were examined using in elastic net regression. RESULTS: The study found seven factors to be particularly strong predictors of SF-36 general health scores. Male gender, "other" sexual identity, stimulant use, and Asian race were all associated with better perceptions of health status, while transgender status, inhalant use, and number of times arrested were associated with poorer perceptions. CONCLUSION: This study suggests targeted areas for health screening within the homeless population; however, more studies are necessary to demonstrate generalizability of the results.

Patient and Provider Perspectives on Medication Non-adherence Among Patients with Depression and/or Diabetes in Diverse Community Settings - A Qualitative Analysis.

Background: Diabetes and depression affect a significant percentage of the world's total population, and the management of these conditions is critical for reducing the global burden of disease. Medication adherence is crucial for improving diabetes and depression outcomes, and research is needed to elucidate barriers to medication adherence, including the intentionality of non-adherence, to intervene effectively. The purpose of this study was to explore the perspectives of patients and health care providers on intentional and unintentional medication adherence among patients with depression and diabetes through a series of focus groups conducted across clinical settings in a large urban area. Methods: This qualitative study utilized a grounded theory approach to thematically analyze qualitative data using the framework method. Four focus groups in total were conducted, two with patients and two with providers, over a one-year period using a semi-structured facilitation instrument containing open-ended questions about experiences, perceptions and beliefs about medication adherence. Results: Across the focus groups, communication difficulties between patients and providers resulting in medication non-adherence was a primary theme that emerged. Concerns about medication side effects and beliefs about medication effectiveness were identified as perceptual barriers related to intentional medication non-adherence. Practical barriers to medication adherence, including medication costs, forgetting to take medications and polypharmacy, emerged as themes related to unintentional medication non-adherence. Conclusion: The study findings contribute to a growing body of research suggesting health system changes are needed to improve provider education and implement multicomponent interventions to improve medication adherence among patients with depression and/or diabetes, both chronic illnesses accounting for significant disease burden globally.

Inpatient Early Intervention for Serious Mental Illnesses Is Associated With Fewer Rehospitalizations Compared With Treatment as Usual in a High-volume Public Psychiatric Hospital Setting.

OBJECTIVE: High-acuity publicly funded inpatient psychiatric settings usually feature short lengths of stay and high readmission rates. This study examined the influence of an early intervention program for serious mental illnesses (SMI) on readmissions at 6 and 12 months postdischarge at a high-volume, urban public inpatient psychiatric hospital. METHODS: The Early Onset Treatment Program (EOTP) is a cost-free, 90-day inpatient multidisciplinary service intervention program for uninsured patients who are within 5 years of SMI onset, funded as a pilot program by the Texas state legislature. Rehospitalization rates at 6 and 12 months were extracted from electronic medical records for EOTP participants (n=165) and comparison patients matched on demographics and diagnosis (n=155). The comparison group received treatment as usual at the same psychiatric hospital. Group re-admission rates were compared using logistic and Poisson regression analyses. RESULTS: Group membership was a significant predictor of rehospitalization (P<0.0001) at both 6 and 12 months. Expressed as 1/odds ratio (OR), the EOTP group was less likely to readmit once and more than once at 6 months postdischarge (1/OR=3.82 and 4.74, respectively) compared with the non-EOTP group. The EOTP group was also less likely to readmit once and more than once at 12 months postdischarge (1/OR=2.96 and 3.51, respectively). CONCLUSIONS: The results suggest that participation in the EOTP service in this high-acuity setting was significantly related to reduced likelihood of rehospitalization at 6 and 12 months. Several variables may account for this observation, including length of stay, longer medication adherence, environmental stability, and more individualized and extensive psychotherapy treatment.

Customizing Early Intervention Treatment for Psychosis in the UTHealth - Harris County Psychiatric Center.

High-need, high-cost patients include those with diagnosed serious mental illnesses (e.g., schizophrenia; SMI). They often delay or fail to seek treatment. If they receive treatment, care is often sought from generalist settings (e.g., primary care or emergency medicine) or is suboptimal due to the provision of limited, non-evidence-based intervention and lack of communication, integration, and coordination among providers. This results in high aggregate costs and poor outcomes. Value-based health care requires care coordination to address the medical and social needs of this population. We describe a unique early intervention program for SMI that emanates from an inpatient setting: The Early Onset Treatment Program (EOTP) at the University of Texas Health Science Center at Houston-Harris County Psychiatric Center. The EOTP offers free, phase-specific, multidisciplinary treatment to young adults without health insurance with the aim of improving their long-term outcomes and reducing the rate of rehospitalization. An evaluation of the EOTP indicates program participants were significantly less likely to be rehospitalized at six months (4.73 times less likely) and at 12 months (3.5 times less likely) than a comparison group (p <.001), and participants' scores of symptomatology and disability significantly decreased following treatment.

Birth Seasonality of Schizophrenia and Bipolar Disorder? A Review of Inpatient Records.

BACKGROUND: Numerous studies on seasonality of birth for mood disorders and schizophrenia have been published but findings are inconsistent 1. We aim to test the hypothesis of lack of seasonal birth differences in hospitalized Bipolar Disorder and Schizophrenia patients. METHODS: 15969 inpatient records in UTHealth Harris County Psychiatric Center between 2012-2014 were enrolled (HSC-MS-14-0274). Patients birth months that were diagnosed as Schizophrenia (n=4178) and Bipolar Disorder (n=5303) according to the DSM IV Criteria were tabulated including admitting diagnosis. Texas Birth statistics between 1903-1997 were obtained as control group (n= 17096471). RESULTS: There was no significant difference for winter births between schizophrenia patients and control group (P=0.738) and there was no significant difference for winter births between bipolar patients and control group either (P= 0.862). Mann Kendall Trend Analysis showed no significant trends of birth months for schizophrenia, bipolar and control groups. LIMITATIONS: The study limitations include being a retrospective study, inability to control for environmental factors, and recruiting from a single location. CONCLUSIONS: Our large sample showed no association between birth season or months with schizophrenia or bipolar disorder. Severe schizophrenia that requires admission may not be related with birth seasonality.

Determinants of High Psychiatric Utilization at a Large Urban Safety-Net Hospital.

Research indicates that high utilizers of the health care system are more likely to have mental illness, to be from socially disadvantaged groups, and to have limited access to community-based services. In this retrospective study, three definitions of high utilization were examined: (1) across time: non-high utilization versus high-utilization, (2) single year versus multi-year, and (3) year-to-year. Univariate logistic regression models were fit to a set of 20 theory-selected predictors of high utilization. An optimal multiple predictor model was then derived via penalized multiple logistic regression (via elastic net, a machine learning algorithm). Three factors were identified in the optimized model as increasing the likelihood of high utilization: having a diagnosis of schizophrenia, having a co-occurring personality disorder diagnosis, and having less than a high school education. Given the complex needs of psychiatric high utilizers, innovative approaches should be considered to improve patient outcomes and reduce costly psychiatric hospitalizations.

Neural changes following equine-assisted therapy for posttraumatic stress disorder: A longitudinal multimodal imaging study.

BACKGROUND: While effective treatments for posttraumatic stress disorder (PTSD) exist, many individuals, including military personnel and veterans fail to respond to them. Equine-assisted therapy (EAT), a novel PTSD treatment, may complement existing PTSD interventions. This study employs longitudinal neuro-imaging, including structural magnetic resonance imaging (sMRI), resting state-fMRI (rs-fMRI), and diffusion tensor imaging (DTI), to determine mechanisms and predictors of EAT outcomes for PTSD. METHOD: Nineteen veterans with PTSD completed eight weekly group sessions of EAT undergoing multimodal MRI assessments before and after treatment. Clinical assessments were conducted at baseline, post-treatment and at 3-month follow-up. RESULTS: At post-treatment patients showed a significant increase in caudate functional connectivity (FC) and reduction in the gray matter density of the thalamus and the caudate. The increase of caudate FC was positively associated with clinical improvement seen immediately at post-treatment and at 3-month follow-up. In addition, higher baseline caudate FC was associated with greater PTSD symptom reduction post-treatment. CONCLUSIONS: This exploratory study is the first to demonstrate that EAT can affect functional and structural changes in the brains of patients with PTSD. The findings suggest that EAT may target reward circuitry responsiveness and produce a caudate pruning effect from pre- to post-treatment.

A randomized, controlled pilot study of cognitive analytic therapy for stressed pregnant women with underlying anxiety and depression in a routine health service setting.

A pilot study of cognitive analytic therapy (CAT) plus treatment as usual (TAU), versus TAU in stressed pregnant women with anxiety and depression, was undertaken as an essential preliminary to any definitive, randomized controlled trial (RCT). The trial was pragmatic, multicentre, parallel, randomized, controlled, and unblinded. Participants were pregnant women screened using the Hospital Anxiety and Depression Scale (HADS). Treatment was standard 16-session CAT. Main outcome measures were Spielberger State/Trait Anxiety Inventory (STAI) (primary outcome measure) at 24 weeks after randomization, therefore 1 month after therapy for the CAT group; HADS; Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM); Edinburgh Postnatal Depression Scale (EPDS); 36-item Short Form Health Survey (SF-36); and a brief Experiences of Therapy Questionnaire, completed at baseline and on average at 12, 24, 40, and 82 weeks after randomization. Thirty-nine patients (CAT + TAU, n = 20; TAU, n = 19) were randomized with mean baseline STAI State scores of 50.8 (SD 11.4) and 51.1 (SD 13.3), respectively. Sixteen patients had missing primary outcome data leaving 23 (n = 11 and n = 12) patients for analysis. The mean STAI State score was 38.5 (SD 13.8) and 45.7 (SD 16.8) in the CAT and TAU groups respectively at 24 weeks after randomization, with an adjusted difference in means of 7.2 (95% confidence interval [CI]: -7.9 to 20.6). No safety issues were reported. Patient retention for the CAT group was high (18/20; 90% of patients completed therapy). Ten out of 11 (90.9%) respondents 'agreed' or 'strongly agreed' that having CAT had been 'very helpful'. The study demonstrated the feasibility of safely undertaking CAT in this setting. Outcomes showed positive trends compatible with a clinically important effect, although statistically definitive conclusions cannot be drawn in such a study.

Race, History of Abuse, and Homelessness Are Associated With Forced Medication Administration During Psychiatric Inpatient Care.

OBJECTIVE: Although previous research has suggested that racial disparities exist in the administration of forced medication (FM) in psychiatric inpatients, data remain scarce regarding other contributing variables. Therefore, this study examined sociodemographic and clinical variables associated with FM administration in psychiatric inpatients. METHODS: Electronic medical records from 57,615 patients admitted to an academic psychiatric hospital between 2010 and 2018 were reviewed to identify patients who received FM. These records indicated that FM petitions were requested and approved for ∼6200 patients. Patients were excluded from the analysis if they met the following exclusion criteria: under 18 years of age, presence of intellectual/developmental disability, dementia, or other neurological condition, or primary diagnosis of a nonpsychiatric medical condition or a substance-induced mood or psychotic disorder. After data on those patients were excluded, the final sample included records from 2569 patients (4.5% of the total records) in which the administration of FM was petitioned for and approved. The FM group was compared with a control group of 2569 patients matched in terms of age, sex, and admission date (no-forced medication group; NFM) via propensity scoring matching. Group comparisons (FM vs. NFM group) examined sociodemographic factors (race, age, sex, living situation), clinical features (diagnosis, substance abuse, history of abuse), and outcomes (length of stay, readmission rate). Regression analyses examined the association between FM and sociodemographic, clinical, and outcome variables. RESULTS: Compared with the NFM group, the FM group contained significantly more African Americans (P<0.001), homeless individuals (P<0.001), and individuals with histories of abuse (P<0.001). Having received FM was a significant predictor of a longer length of stay (P<0.001) and higher readmission rates (P<0.001). DISCUSSION: These results suggest that FM is more likely to be instituted in psychiatric inpatients who are of a minority race (African American), are in a homeless living situation, and/or have a history of abuse. Moreover, FM may be associated with poorer clinical outcomes at least as measured by the length of stay and higher readmission rates. We discuss possible reasons for these results and the importance of culturally competent and trauma-focused care.

Equine-Assisted Therapy for Veterans with PTSD: Manual Development and Preliminary Findings.

INTRODUCTION: Equine-assisted therapy (EAT) for post-traumatic stress disorder (PTSD) has attracted great interest despite lacking empirical support, a manual, and a standardized protocol. Our team of experts in EAT and PTSD developed an eight-session group EAT treatment protocol for PTSD (EAT-PTSD) and administered it to two pilot groups of military veterans to assess initial effects. MATERIALS AND METHODS: We describe the development of the treatment manual, which was used with two pilot groups of veterans. Protocol safety, feasibility, and acceptability were assessed by reported adverse events, treatment completion rates, and self-rated patient satisfaction. Preliminary data on PTSD, depressive, and anxiety symptoms and quality of life were collected pretreatment, midpoint, post-treatment, and at 3-month follow up. RESULTS: No adverse events were recorded. All patients completed treatment, reporting high satisfaction. Preliminary data showed decreases in clinician-assessed PTSD and depressive symptoms from pre to post-treatment and follow-up (medium to large effect sizes, d = .54-1.8), with similar trends across self-report measures (d = 0.72-1.6). In our pilot sample, treatment response and remission varied; all patients showed some benefit post-treatment, but gains did not persist at follow-up. CONCLUSIONS: This article presents the first standardized EAT protocol. Highly preliminary results suggest our new manualized group EAT-PTSD appears safe, well-regarded, and well-attended, yielding short-term benefits in symptomatology and quality of life if unclear length of effect. Future research should test this alternative treatment for PTSD more rigorously.

Ontological representation-oriented term normalization and standardization of the Research Domain Criteria.

The Research Domain Criteria, launched by the National Institute of Mental Health, is a new dimensional and interdisciplinary research framework for mental disorders. The Research Domain Criteria matrix is its core part. Since an ontology has the strengths of supporting semantic inferencing and automatic data processing, we would like to transform the Research Domain Criteria matrix into an ontological structure. In terms of data normalization, which is the essential part of an ontology representation, the Research Domain Criteria elements (mainly in the Units of Analysis) have some limitations. In this article, we propose a series of solutions to improve data normalization of the Research Domain Criteria elements in the Units of Analysis, including leveraging standard terminologies (i.e. the Unified Medical Language System Metathesaurus), context-combining queries, and domain expertise. The evaluation results show the positive (Yes) percentage is more than 80 percent, indicating our work is favorably received by the mental health professionals, and we have formed a good data foundation for the Research Domain Criteria ontological representation in the future work.

Cannabis use: A co-existing condition in first-episode bipolar mania patients.

BACKGROUND: An association between first-episode presentation of bipolar mania and concurrent cannabis use disorder has been well established in the current literature (Bally et al., 2014, Baethge et al., 2008). Previous studies have shown that 30-70% of patients admitted for a first manic episode had concurrent cannabis use (Bally et al., 2014). The exact mechanism of this association has yet to be confirmed. AIMS: We aim to evaluate the prevalence of cannabis use in patients with bipolar disorder (BD) admitted to UTHealth Harris County Psychiatric Center (HCPC) for a first manic episode. METHODS: In this retrospective cohort study, 15,969 inpatient records of patients admitted to HCPC between 2012-2013 were examined to identify patients admitted with a first manic episode according to ICD-9 criteria (single episode mania). The prevalence of multiple sociodemographic and clinical variables including cannabis positivity in urine drug screening (UDS) were examined. RESULTS: Twenty patients were admitted for a first manic episode. Half of the patients were females; mean age was 28.65 ± 10.56 years and mean length of stay (LOS) was 7.15 ± 3.72 days. Fifteen patients received a UDS. Of these fifteen, seven were positive for cannabinoids (47%). One patient was positive for phencyclidine (in addition to cannabis) and one patient was positive for amphetamine (but not cannabis). CONCLUSIONS: The prevalence of cannabis use was higher in first-episode mania patients compared to the general population. The influence of cannabis on the first episode of mania requires additional study.

Treatment Retention Among Patients Participating in Coordinated Specialty Care for First-Episode Psychosis: a Mixed-Methods Analysis.

Young adults experiencing first-episode psychosis have historically been difficult to retain in mental health treatment. Communities across the United States are implementing Coordinated Specialty Care to improve outcomes for individuals experiencing first-episode psychosis. This mixed-methods research study examined the relationship between program services and treatment retention, operationalized as the likelihood of remaining in the program for 9 months or more. In the adjusted analysis, male gender and participation in home-based cognitive behavioral therapy were associated with an increased likelihood of remaining in treatment. The key informant interview findings suggest the shared decision-making process and the breadth, flexibility, and focus on functional recovery of the home-based cognitive behavioral therapy intervention may have positively influenced treatment retention. These findings suggest the use of shared decision-making and improved access to home-based cognitive behavioral therapy for first-episode psychosis patients may improve outcomes for this vulnerable population.

A qualitative study investigating bipolar patients' expectations of a lifestyle intervention: A self-management program.

BACKGROUND: There is some evidence supporting the efficacy of lifestyle interventions in changing unhealthy habits and reduce the risk of developing comorbid conditions in Bipolar Disorder (BD). AIMS: This qualitative study aimed to identify what an optimal lifestyle intervention would look like for individuals with BD. METHODS: The current findings are based on one focus group and two paired interviews including a total of 10 individuals with BD (44.20 ±â€¯11.11 years; 6 females). Groups' transcripts were analyzed using a narrative approach. Primary themes included facilitating factors and barriers, general content, outcomes, format of the intervention, and background factors. RESULTS: Participants were in favor of a group-based lifestyle intervention as part of their usual treatment. The optimal group format would include 4 to 10 individuals, and comprise of 12 to 18 sessions lasting 1 to 1.5 h each. Accountability, motivation, interaction, and group activities were identified as contributing to the success of a lifestyle intervention. CONCLUSIONS: This qualitative study provides important information regarding aspects of lifestyle intervention format and delivery for individuals with BD. We identified barriers and facilitating factors that should be addressed in health promotion interventions delivered within community mental health settings.

Ethnic differences in the diagnosis of schizophrenia and mood disorders during admission to an academic safety-net psychiatric hospital.

U.S. Hispanics, now the single largest minority group in the country, face unique mental health disparities. The current study utilizes Andersen's Behavioral Model of Health Service Use to examine ethnic disparities in receiving a schizophrenia or mood disorder diagnosis at psychiatric hospital admission. Our retrospective cohort study examined electronic health record data at an academic safety-net psychiatric hospital for adult patients (n = 5571) admitted between 2010 and 2013. Logistic regression with block-wise entry of predisposing, enabling and need variables was used to examine ethnic disparities in receiving a schizophrenia diagnosis at admission. The block of need factors was the strongest predictor of receiving a schizophrenia diagnosis compared to predisposing and enabling factors. Compared to non-Hispanic whites, Hispanics and African Americans had a greater likelihood of receiving a schizophrenia diagnosis at admission. Additionally, patients diagnosed with schizophrenia had elevated positive and negative symptoms and were more likely to be male, single/unmarried, homeless, high inpatient service utilizers, involuntarily hospitalized, and to exhibit functional impairment at psychiatric hospital admission. To address elevated positive and negative symptoms of schizophrenia, functional impairment, social withdrawal, and high inpatient service utilization, promising psychosocial interventions should be adapted for racial and ethnic minority populations and utilized as an adjuvant to antipsychotic medication.

First-episode psychosis: Ongoing mental health service utilization during the stable period for adolescents.

AIM: The timely identification and treatment of psychosis are increasingly the focus of early interventions, with research targeting the initial high-risk period in the months following first-episode hospitalization. Ongoing treatment after stabilization is also essential in the years following a first-episode psychosis (FEP), but has received less research attention. In this study, variables that could impact continued psychiatric service utilization by adolescents following their FEP and temporal patterns in service utilization are examined. METHODS: Families of 52 adolescents (aged 14.4 ± 2.5 years) discharged following a hospitalization for FEP were contacted two or more years following the adolescents' discharge. A chart review (Time 1) of hospital records provided clinical data on each adolescent's psychiatric diagnosis, symptoms, illness course, medications and family history. Follow-up (Time 2) data were collected from parents/caregivers using a questionnaire enquiring about post-discharge treatment history and service utilization. RESULTS: Bivariate analyses were conducted to identify Time 1 variables associated with psychiatric service utilization at Time 2. Significant variables were included in a logistic regression model and three variables were independently associated with continued service utilization: having a primary diagnosis of schizophrenia (odds ratio (OR) = 24.0; P = 0.02), not having a first-degree relative with depression (OR = 0.12; P = 0.05) and fewer months since the last inpatient discharge (OR = 0.92; P = 0.02). CONCLUSIONS: Findings suggest: (1) the importance of early diagnosis, (2) that a relative with depression may negatively influence the adolescent's ongoing service utilization, and (3) that 18 months post-discharge may be a critical time to review treatment strategies and collaborate with youth and families to ensure appropriateness of services.
