Ensuring the fit of an evidence-based curriculum for high-risk Latina young mothers using implementation science

Conduct a comprehensive needs assessment to evaluate the fit of a Cognitive Behavioral Theory (CBT) curriculum implemented within a community organization and inform possible adaptations to fit the mental health difficulties of high-risk Latina young mothers. The PRECEDE-PROCEED implementation framework guided the assessment and results. Focus groups were conducted with high-risk Latina young mothers and staff members to assess the priority mental health problems, environmental stressors and factors contributing and maintaining these difficulties, and existing resources that could be leveraged to address them. Latina young mothers experience a variety of mental health needs and immigration and interpersonal-related stressors. The organization's existing CBT curriculum was found to be feasible and a good fit for the target population. Proposed minor adaptations included a focus on parenting. Results support the robust effects of CBT interventions, including when delivered by paraprofessionals to a high-risk population in a low-resource community setting.

Community-Based Implementation of a Paraprofessional-Delivered Cognitive Behavioral Therapy Program for Youth Involved with the Criminal Justice System

Psychosocial interventions for common emotional and behavioral difficulties have been developed for use in correctional facilities, yet these programs are largely unavailable upon community re-entry due to a shortage of trained mental health specialists. In this study, we developed and piloted a youth worker-delivered cognitive behavioral therapy (CBT) program for young men at high risk for incarceration receiving services at a youth development organization. We formed a community-academic partnership to support the conduct of research across all phases of this project (2014-2016). We analyzed data gathered through focus groups and individual interviews with program staff, administrators, and young men. This study reports on implementation process and outcomes across phases. Main findings indicate the preliminary feasibility and acceptability of the youth worker-delivered CBT curriculum. We discuss strengths and limitations of our approach and provide suggestions for future studies that aim to implement paraprofessional-delivered CBT programs within community-based organizations.

Client-level predictors of treatment engagement, outcome and dropout: moving beyond demographics

Background

Despite the availability of evidence-based treatments for posttraumatic stress disorder (PTSD), significant heterogeneity in the effectiveness of PTSD treatment persists, especially in community settings. Client demographics used to understand this variability in treatment outcome and dropout have yielded mixed results. Despite increasing evidence for the importance of attending to treatment engagement in community settings, few studies have explored client-level predictors.

Aim

The purpose of this study is to explore client-level predictors of treatment outcome and dropout beyond client demographics, and to identify client-level predictors of treatment engagement in community settings.

Method

Secondary data analysis was conducted with data collected as part of an implementation-effectiveness hybrid study of cognitive processing therapy (CPT) for PTSD in a diverse community health centre. Providers (n=19) treated (n=52) clients as part of their routine clinical care. Non-demographic client-level predictors included barriers to treatment, quality of life, session-level language and employment history assessed at baseline. Treatment engagement included number of weeks in the study, number of sessions with repeated CPT content, number of unique CPT sessions attended, frequency of session attendance and consistency of session attendance.

Results

Results showed language as a significant predictor of treatment engagement. There were significant differences between Spanish and English-speaking clients, with the former having a tendency to repeat more session content than the latter (β=1.4 sessions, p=0.003), and also less likely to attend treatment frequently (r=0.62, p=0.009) and consistently (r=0.57, p=0.027) if high logistical and financial barriers were endorsed. Irrespective of language, clients who reported high quality of life at baseline were less likely to repeat CPT session content (β=−0.3, p=0.04), and those with increased baseline barriers to treatment had deceleration in PTSD symptom improvement over time (β=−0.62, p<0.05). In terms of treatment engagement moderators impacting treatment outcome, clients who repeated more session content were more likely to complete treatment (OR=1.84, p=0.037).

Conclusion

Identification of client-level predictors of treatment engagement, outcome and dropout is essential to optimise treatment, particularly in community settings.

Facilitators of and barriers to high-resolution anoscopy adherence among men who have sex with men: a qualitative study

Background Anal cancer is a rare malignancy that disproportionately affects men who have sex with men (MSM) and HIV-infected people. Anal cancer is associated with human papillomavirus (HPV) in upward of 90% of cases and is preceded by pre-cancerous changes in cells of the anal canal. High-resolution anoscopy (HRA) is used for the detection, treatment and continued monitoring of anal dysplasia. Practice guidelines regarding anal cancer prevention vary by jurisdiction and institution, and patient engagement is low for high-risk populations such as MSM. The purpose of this study is to characterise perceptions among MSM of barriers to and facilitators of their adherence to HRA follow-up recommendations.

METHODS

Surveys and in-person focus groups with MSM who were either adherent or non-adherent to HRA follow-up recommendations at a Federally Qualified Health Centre in Boston, MA, which specialises in sexual and gender minority care, were conducted. Facilitators of and barriers to follow-up were identified by deductive content analysis.

RESULTS

Focus group participants identified the following barriers to and facilitators of HRA follow up: (1) patient-level beliefs about HPV-related disease or HRA, ability to engage in care, internalised stigma and physical discomfort; (2) provider-level knowledge and expertise, communication skills and relationship-building with patient; and (3) systems-level societal stigma and healthcare system inefficiencies.

CONCLUSIONS

Reinforcing facilitators of and reducing barriers to HRA follow up may improve adherence among MSM. This includes improvements to: patient education, provider training to increase knowledge and cultural sensitivity, public awareness about HPV-related anal cancer, physical discomfort associated with HRA and systems inefficiencies.

Provider fidelity and modifications to cognitive processing therapy in a diverse community health clinic: Associations with clinical change

OBJECTIVE

The purpose of this study is to examine associations between therapist adherence, competence, and modifications of an evidence-based protocol (EBP) delivered in routine clinical care and client outcomes.

METHOD

Data were derived from a NIMH-funded implementation-effectiveness hybrid study of Cognitive Processing Therapy (CPT) for PTSD in a diverse community health center. Providers (n = 19) treated clients (n = 58) as part of their routine clinical care. Clients completed the PCL-S and PHQ-9 at baseline, after each CPT session, and posttreatment. CPT sessions were rated for treatment fidelity and therapist modifications.

RESULTS

Overall, therapist adherence was high, although it decreased across sessions suggesting potential drift. Therapist competence ratings varied widely. Therapists made on average 1.6 fidelity-consistent and 0.4 fidelity-inconsistent modifications per session. Results show that higher numbers of fidelity-consistent modifications were associated with larger reductions in posttraumatic stress and depressive symptoms. High adherence ratings were associated with greater reductions in depressive symptoms, whereas higher competence ratings were associated with greater reduction in posttraumatic stress symptoms.

CONCLUSIONS

The results highlight the importance of differentially assessing therapist adherence, competence, and modifications to EBP in usual care settings. The findings also suggest that effective EBP delivery in routine care may require minor adaptations to meet client needs, consistent with previous studies. Greater attention to fidelity and adaptation can enhance training so providers can tailor while retaining core components of the intervention.

Practical solutions for sustaining long-term academic-community partnerships

The science-practice gap in the treatment of mental health is most pronounced in community settings, where clients with the highest needs often receive their care. Implementation science and community-based participatory research strategies aim to effectively address this gap by establishing partnerships that focus on scientifically rigorous, as well as clinically and socially relevant, research. Despite significant benefits, the community-based participatory research implementation framework has a unique set of challenges. The current article describes evidence-supported implementation strategies that were deployed to address various barriers to the implementation and long-term sustainability of an innovative cognitive-behavioral theory (CBT) life skills program identified during a feasibility trial. Through the committed work of an established partnership between a community-based nonprofit organization and researchers, barriers and the strategies for mitigating these obstacles were jointly identified. Specific challenges included fidelity (variability in staff's CBT competency and delivery), sustainability, and the cost of guideline implementation (data collection, time, and resources) of the CBT curriculum. We also provide details on the partnership's solutions to these major obstacles, including the development of an intensive 3-month training and coaching phase. The results of this rigorous training suggest improvement in staff's overall CBT competency and fidelity, increased participant engagement in the CBT curriculum, and enhanced data-collection procedures; yet, sustainability difficulties remained. General recommendations for long-term community research partnerships include early organizational buy-in; comprehensive needs assessments, including the organization's research building capacity; and sustained training and coaching models.

Primary Care Provider Practices and Perceptions Regarding HPV Vaccination and Anal Cancer Screening at a Boston Community Health Center

Human papillomavirus (HPV) vaccination and anal cancer screening are valuable, yet underutilized, tools in prevention of HPV-related cancers among sexual and gender minority (SGM) populations. The aim of this study was to characterize primary care providers' (PCPs) practices and perceptions pertaining to HPV vaccination and anal cancer screening. A survey assessing self-reported practice characteristics related to HPV vaccination and anal cancer screening, as well as perceived barriers to vaccination and anal cancer screening at the patient-, provider-, and system-level was distributed to PCPs at a Federally-Qualified Health Center that specializes in care for SGM populations in the greater Boston area. A total of 33 PCPs completed the survey. All PCPs strongly recommended HPV vaccination to their patients by emphasizing that the vaccine is extremely important or very important. Most PCPs told their patients that the HPV vaccine prevents cervical cancer (96.9%), anal cancer (96.9%), oropharyngeal cancer (72.7%), penile cancer (57.5%), and genital warts (63.6%). There is substantial variability among providers regarding recommendations for anal cancer screening and follow-up. Most PCPs perceived that patient-level factors such as poverty, mental illness, and substance use disorders were barriers to HPV vaccination and anal cancer screening. Systems-level barriers such as lack of clinical time with each patient and lack of staffing were also described as barriers to vaccination and screening. Patient-, provider- and systems-level improvements are important to increase HPV vaccination and anal cancer screening rates.

Three-dose HPV vaccine completion among sexual and gender minority young adults at a Boston community health center

BACKGROUND

Disparities in human papillomavirus (HPV) vaccination completion have been noted among sexual and gender minority (SGM) people. Little is known about factors associated with HPV vaccination among SGM people. This study examines factors linked with completion of HPV vaccination among SGM patients.

METHODS

We collected cross-sectional data from electronic health records (EHRs) of SGM patients receiving primary care at a Boston community health center specialized in SGM health. We employed a binomial logistic regression model to identify factors associated with 3-dose HPV vaccine completion.

RESULTS

Patients were 70.3% white, with mean age of 26.3 years (SD = 2.48), 26.9% identifying as gender minorities and 79% as sexual minorities, 48.9% with 4-year college or graduate degrees, 59.4% employed, 65.9% with private insurance, 39.1% living at or below the federal poverty level, and 8.3% living with HIV. Seventy-seven percent of patients who were offered HPV vaccination had completed the series. Factors significantly associated with HPV vaccine completion included: 4-year college or graduate degree (OR: 2.87; 95% CI = 1.26-6.53), completion of primary care appointments (OR: 1.03; 95% CI: 1.01-1.05), Hepatitis A or B vaccine completion (OR: 2.59; 95% CI: 1.2-5.59), and visits for a sexually transmitted infection (STI) screen (OR: 1.22; 95% CI: 1.03-1.43).

CONCLUSION

Vaccine completion was higher among SGM with higher levels of education, Hepatitis A or B vaccination, and completed health visits. These findings highlight potential ways to increase HPV vaccination, such as offering tailored HPV vaccine education, bundling with other vaccines, and incorporating HPV vaccination with STI screenings.

Factors associated with anal cancer screening follow-up by high-resolution anoscopy

OBJECTIVES

High-resolution anoscopy (HRA) is a potential screening method for detection of anal cancer precursors. We evaluated factors associated with adherence to recommended HRA follow-up time intervals among men who have sex with men (MSM).

METHODS

We employed a retrospective, observational cohort study with 155 MSM screened by HRA between 1 April 2011 and 31 March 2016 at a Federally Qualified Health Centre in Boston, Massachusetts.

RESULTS

The sample was 80% white, with a median age of 48 (non-normal distribution, IQR 15). All patients were assigned male sex at birth and none identified as transgender. Fifty patients (32%) followed up with a HRA appointment within 6 months of previous HRA detection of anal high-grade squamous intraepithelial lesion (HSIL). Among patients, 112 (72%) were HIV infected, 56 (36%) had a syphilis diagnosis during the study period, 89 (57.4%) had initiated Hepatitis A or B vaccination series, 70 (45.2%) accessed case management services and 19 (12.3%) utilised pre-exposure prophylaxis (PrEP). In bivariate analysis, patients who underwent recommended follow-up HRA within 6 months of HSIL diagnosis were less likely to report: case management utilisation (p=0.023), initiation of Hepatitis A or B vaccination (p=0.047), HIV diagnosis (p<0.001) and syphilis diagnosis (p=0.001), but were more likely to use HIV PrEP (p<0.001). In binomial logistic regression modelling after adjusting for age and race/ethnicity, patients who had follow-up with HRA within a recommended period of 6 months after HSIL diagnosis were less likely to have initiated Hepatitis A or B vaccination (adjusted OR 0.43, 95% CI 0.20 to 0.94), more likely to use PrEP (adjusted OR 4.47, 95% CI 1.30 to 15.49) and less likely to have a syphilis diagnosis (adjusted OR 0.34, 95% CI 0.14 to 0.86).

CONCLUSIONS

Three-quarters of patients with HSIL did not have follow-up HRA within the clinic's recommended follow-up period of 6 months following HSIL diagnosis by HRA. Future studies ought to explore whether addressing anal health during other STI-related care helps improve adherence to recommended time intervals for follow-up HRA. Given the high prevalence of STI and PrEP use, studies might also evaluate whether integrating HRA follow-up with other sexual health screenings helps improve adherence to recommended HRA follow-up.

The association of posttraumatic stress disorder and chronic medical conditions by ethnicity

Our study extends the literature on associations between posttraumatic stress disorder (PTSD) and chronic medical conditions by assessing differences in the magnitude of these relations by ethnicity. We examined group differences in the magnitude of the relation between PTSD and chronic medical conditions (cardiovascular disease [CVD], hypertension, obesity, diabetes). We obtained data from Latino (n = 3,224) and non-Latino white (n = 4,180) respondents from the Collaborative Psychiatric Epidemiology Surveys. Logistic regression models were constructed to test for the modification of the effect of PTSD on chronic medical conditions by ethnicity, and then by nativity. Unadjusted models revealed significant interactions between Latino ethnicity and PTSD for odds of diabetes (OR = 2.18 [Latino] v. 0.81 [non-Latino white]), CVD (OR = 3.23 [Latino] v. 1.28 [non-Latino white]), and hypertension (OR = 1.61 [Latino] v. 0.98 [non-Latino white]). Among U.S.-born Latinos, we found a significant interaction between ethnicity and PTSD for odds of CVD (OR = 4.18 [Latino] v. 1.28 [non-Latino white]) and diabetes (OR = 2.27 [Latino] v. 0.81 [non-Latino white]). These findings attenuated in adjusted models with the exception of differences in PTSD and odds of diabetes among Latinos (including aggregated group & U.S.-born) compared to non-Latino whites. Our findings support the need for further research on the complex relations between PTSD and chronic conditions, including the investigation of conditional risk by Latino sub-groups.

Usual Course of Treatment and Predictors of Treatment Utilization for Patients With Posttraumatic Stress Disorder

OBJECTIVE

Posttraumatic stress disorder (PTSD) is a debilitating psychiatric illness that frequently remains undiagnosed and untreated. While extensive research has been conducted among veterans, little research has evaluated course of treatment for PTSD in a general hospital setting.

METHODS

We utilized data from the Partners HealthCare Research Patient Data Registry to evaluate mental health treatment utilization, including psychotherapy and pharmacotherapy, by patients with recently diagnosed primary PTSD following DSM-IV criteria between January 1, 2002, and June 30, 2011. We additionally evaluated predictors of treatment utilization 6 months postdiagnosis.

RESULTS

Among 2,475 patients with recently diagnosed primary PTSD, approximately half (55.7%) had any therapy visit and 10% had at least 12 therapy visits in the 6 months following diagnosis. Approximately half (47.0%) received a psychiatric prescription, with 29.3% receiving a selective serotonin reuptake inhibitor (SSRI), 11.8% receiving an atypical antipsychotic, and 24.4% receiving a benzodiazepine. Latinos were 25% (95% CL = 1.09, 1.43) more likely to have an SSRI prescription, 35% (95% CL = 1.05, 1.75) more likely to have an atypical antipsychotic prescription, and 28% (95% CL = 1.19, 1.38) more likely to receive any psychotherapy. Women were 49% (95% CL = 0.42, 0.63) less likely to have an atypical antipsychotic prescription. Patients with Medicare were 23% (95% CL = 0.67, 0.88) less likely to have any psychotherapy, and patients with Medicaid were 35% (95% CL = 0.46, 0.92) less likely to have 12 or more therapy visits.

CONCLUSIONS

Many patients with a primary diagnosis of PTSD do not receive psychotherapy, and psychiatric prescriptions, including atypical antipsychotics and benzodiazepines, are common. Future research is needed to determine the quality of care received and explore subpopulation-specific barriers limiting access to care.

Residential segregation and mental health among Latinos in a nationally representative survey

BACKGROUND

Among Latinos, living in a locality with greater Latino ethnic density may be protective for mental health, although findings vary by Latino subgroup, gender and birthplace. Although little studied, Latino residential segregation may capture different pathways linking risk and protective environmental factors to mental health than local ethnic density.

METHODS

This study evaluated the association between residential segregation and mental distress as measured by the Kessler-10 (K10) among Latino participants in the National Latino and Asian American Study (NLAAS). Census data from 2000 was used to calculate metropolitan statistical area (MSA) residential segregation using the dissimilarity and isolation indices, as well as census tract ethnicity density and poverty. Latino subgroup (Puerto Rican, Mexican American, Cuban American and other Latino subgroup), gender and generation status were evaluated as moderators.

RESULTS

Among 2554 Latino participants in NLAAS, residential segregation as measured by the isolation index was associated with less mental distress (β -0.14, 95% CI -0.26 to -0.03 log(K10)) among Latinos overall after adjustment for ethnic density, poverty and individual covariates. Residential segregation as measured by the dissimilarity index was significantly associated with less mental distress among men (β -0.56, 95% CI -1.04 to -0.08) but not among women (β -0.20, 95% CI -0.45 to 0.04, p-interaction=0.019). No modification was observed by Latino subgroup or generation.

CONCLUSIONS

Among Latinos, increasing residential segregation was associated with less mental distress, and this association was moderated by gender. Findings suggest that MSA-level segregation measures may capture protective effects associated with living in Latino communities for mental health.

Black-white disparities in the association between posttraumatic stress disorder and chronic illness

OBJECTIVE

Non-Latino blacks experience a higher proportion of chronic illness and associated disabilities than non-Latino whites. Posttraumatic stress disorder (PTSD) is associated with a greater risk of chronic illness, although few studies have investigated whether the interaction of PTSD with racial disparities may lead to a greater risk of chronic illness among blacks with PTSD than among whites with PTSD.

METHODS

We evaluated data from the population-based National Survey of American Life and the National Comorbidity Survey Replication to investigate the association between race, lifetime PTSD and self-reported chronic illness. Weighted linear and Poisson regression models assessed differences in the magnitude of association between PTSD and chronic illness by race on both the additive and multiplicative scales.

RESULTS

The magnitude of the association between lifetime PTSD and diabetes was greater among blacks (RD 0.07, 95% CI 0.02, 0.11; RR 1.9, 95% CI 1.4, 2.5) than whites (RD 0.004, 95% CI -0.02, 0.03; RR 1.2, 95% CI 0.7, 1.9) on the additive (p=0.017) scale. The magnitude of the association between lifetime PTSD and heart disease was greater among blacks (RD 0.09, 95% CI 0.05, 0.13) than whites (RD 0.04, 95% CI 0.01, 0.07) on the additive scale at a level approaching significance (p=0.051).

CONCLUSION

A lifetime history of PTSD was associated with a significantly greater risk of diabetes among blacks as compared to whites. These findings suggest that continuous exposure to racial inequalities may be associated with a greater risk of PTSD-related health sequela.

Longitudinal Study of Mental Health and Pain-Related Functioning Following a Motor Vehicle Collision

OBJECTIVE

Relations between mental and physical health symptoms are well-established in the literature on recovery following motor vehicle collisions (MVCs). To understand the temporal sequencing and evolution of these relations, we examined the bidirectional association between mental and physical health symptoms at 4 and 16 weeks following a MVC.

METHODS

The sample consisted of 103 participants recruited through public MVC police reports. The study included self-report assessments for posttraumatic stress symptoms, depressive symptoms, bodily pain, and role limitations attributable to physical health. A series of multivariable linear regression analyses were conducted to estimate the associations between these mental and physical health outcomes.

RESULTS

The analysis revealed that mental health symptoms at 4 weeks post-MVC were associated with higher bodily pain at 16 weeks post-MVC (PTSD symptoms: β = -0.74, 95% CI: -1.06, -0.42; depressive symptoms: β = -1.34, 95% CI: -1.90, -0.78), but not higher health-related role limitations. Physical health symptoms at 4 weeks post-MVC were not associated with PTSD or depressive symptoms at 16 weeks post-MVC.

CONCLUSIONS

The results indicate the predictive strength of mental health symptoms at 4 weeks post-MVC in identifying individuals at risk for bodily pain at 16 weeks and shed light on the temporal sequencing of how relations between physical and mental health symptoms emerge over time. This suggests that early assessment of mental health symptoms may have significant implications for the treatment of these patients. (PsycINFO Database Record

Mental illness stigma and engagement in an implementation trial for Cognitive Processing Therapy at a diverse community health center: a qualitative investigation

The present study aimed to describe associations between various types of mental health stigma and help-seeking behaviors among ethnically diverse clients with posttraumatic stress disorder (PTSD) served by an urban community health clinic. The present study draws qualitative data from a parent National Institute of Mental Health Study that aims to identify barriers and facilitators of implementing Cognitive Processing Therapy (CPT) for PTSD. A total of 24 participants from the initial phase of the trial were included in the present study. Mental health stigma emerged as one notable barrier to seeking mental health treatment, as participants described how experiences of environment-level stigma, internalized (self-)stigma and perceived (felt) stigma from their family, friends and previous healthcare providers influenced their decisions to seek care. Despite these barriers to help seeking, many clients also reported that positive interactions with informal and formal support systems, and encouragement from study therapists, helped to combat mental health stigma and facilitate decisions to participate in an implementation trial for CPT. Findings suggest that providers in community health settings may need to attend directly to stigma at the initiation of mental health treatment.

Development and delivery of a quality improvement program to reduce antipsychotic polytherapy

BACKGROUND

Although antipsychotic polytherapy is considered appropriate in limited circumstances (e.g., during a brief "cross-titration" period when switching medications), its increasing prevalence indicates use beyond this limited scope. Despite absence of support in the medical literature and higher costs, antipsychotic polytherapy is common in the treatment of schizophrenia and related disorders. The highest utilization of antipsychotic polytherapy occurs on psychiatric inpatient units, and in 2008, the Joint Commission released the first set of 7 hospital-based inpatient psychiatric services (HBIPS) core measures, 2 of which assess antipsychotic polytherapy at time of discharge.

OBJECTIVE

To describe the effect on antipsychotic polytherapy at time of discharge of a 2-part quality improvement program composed of educational seminars and prescriber-specific feedback provided to 11 psychiatrists in 4 acute inpatient psychiatric units in 2 hospitals.

METHODS

In a regional academic health care system, we determined the prevalence of antipsychotic monotherapy and polytherapy at time of discharge for all patients discharged on standing antipsychotic medications during 3 periods: (a) a 3-month baseline period (August 2006 through October 2006); (b) in July 2007, after delivery of 4 educational luncheon seminars to 11 psychiatrists from November 2006 through June 2007; and (c) in June 2008, following the provision of monthly prescriber-specific audit feedback from August 2007 through June 2008. To prepare nurses for the change and address possible safety concerns, an educational module was delivered to the psychiatric nursing staff at "best practice" day lectures held in the first quarter of 2007. General themes in the educational presentations included literature-based reviews of (a) safety and efficacy of antipsychotic polytherapy, (b) medical risks of antipsychotic medications, (c) specific versus nonspecific effects of these medications, and (d) effectiveness of first- versus second-generation antipsychotic medications. The prescriber-specific audit feedback was provided in paper form and masked the identity of the other prescribers. The chief of service reviewed audit feedback individually with each psychiatrist on a quarterly basis. The primary outcome measure was the percentage of patients prescribed 2 or more antipsychotics at discharge. A secondary outcome measure was the percentage of patients prescribed 3 or more antipsychotics at discharge. Differences in the primary outcome measure, comparing (a) July 2007 with the baseline period and (b) June 2008 with July 2007, were analyzed using Fisher's Exact tests. The Cochran-Armitage test for trend was used to assess the relationship between the primary outcome measure and the extent of the intervention, measured as the 3 time periods. For the secondary outcome measure, the Goodman-Kruskal gamma test for ordered categorical data was calculated to examine the association between the the proportion of patients receiving 1, 2, or 3 or more antipsychotics at discharge and the 3 time periods.

RESULTS

The percentage of patients prescribed 2 or more antipsychotics at discharge declined from 33.9% at baseline (132 of 389 patients), to 21.8% after delivery of the educational modules (44 of 202 patients, P = 0.002), and to 12.2% after audit feedback (18 of 147 patients, P = 0.023; Cochran-Armitage test for trend P < 0.001). When antipsychotic use was classified as 1, 2, or 3 or more antipsychotic medications, more extensive intervention was associated with decreased combination use (Goodman- Kruskal gamma = 0.39, P < 0.001). In the baseline period, 5.9% of patients were prescribed 3 or more antipsychotics at discharge. Following completion of the educational and audit components, respectively, the proportion of patients prescribed 3 or more antipsychotics declined to 2.5% and then to 0.0%.

CONCLUSION

Educational modules presented to psychiatrists and nurses in group settings were associated with a decrease in the rate of prescribing 2 or more antipsychotics at discharge from acute psychiatric inpatient units. Addition of monthly audit feedback provided to psychiatrists was associated with further decreases.

Normative neuropsychological test performance: effects of age, education, gender and ethnicity

Normative data on neuropsychological test performance for a sample of 131 adults (ages 18-49) is presented. All subjects were native speakers of English screened for past or present medical, neurological and psychiatric disorders, including substance abuse. A broad-based battery including measures of intellectual skills, memory and learning, receptive and expressive language, auditory and visual information processing and attention, sensory processing, motor skills, and self-reported anxiety and depression was administered. Means, standard deviations and percentile rankings for all tests are reported. Regression analyses were computed to consider the concurrent influence of sociodemographic factors on all tests. Significant effects of age (M=27.1 yrs), education (M=14.6 yrs), gender (58% male), and ethnicity (62% white) were observed for relatively few test scores. Younger age at testing was associated with better continuous performance test scores. Higher education levels were associated with higher vocabulary and reading scores. Males had higher WAIS-R Information scores and faster Finger Tapping scores compared to females Ethnicity was associated with Full-scale IQ, and additional tests with a verbal component, e.g., Boston Naming Tests, and non-verbal component, e.g., Drawing Tests. We conclude that sociodemographic factors infrequently account for more than 10% of the variance for many neuropsychological test scores.

Frontal and temporal lobe brain volumes in schizophrenia. Relationship to symptoms and clinical subtype

BACKGROUND

Quantitative magnetic resonance imaging (MRI) studies demonstrate reduced brain volumes in schizophrenics, but specific structural abnormalities have not been clearly delineated. The structural abnormalities of this disorder are likely to be heterogeneous, consistent with its diverse clinical presentation. To investigate the relationship between structural abnormality and clinical symptoms, we examined regional brain and cerebral spinal fluid (CSF) volumes in a large sample of schizophrenic patients and controls, with patients aggregated into clinical subtypes.

METHODS

Right and left hemisphere frontal and temporal lobe brain and CSF volumes were quantified from 5-mm axial spin-echo MRIs for 71 schizophrenic patients and 77 age- and sex-matched controls. The following four standardized rating scales were used to assess symptom severity: Negative Symptoms, Disorganization, Schneiderian Delusions and Hallucinations, and Suspicion-Hostility. Patients were also subtyped as either deficit or nondeficit on the basis of enduring negative symptoms.

RESULTS

Schizophrenic patients overall exhibited abnormal brain asymmetry, with selective decrease in brain volume in the left temporal and right frontal regions. Left temporal lobe parenchymal volume reduction and CSF volume increase were correlated with the severity of negative symptoms. Consistent with this, the subtype analysis revealed abnormal temporal lobe asymmetry for the deficit subgroup only. Right frontal lobe volume reduction correlated with the duration of illness, independent of symptom severity or schizophrenic subtype.

CONCLUSIONS

Abnormal lateral asymmetry suggests selective structural deficits in schizophrenia, rather than diffusely undifferentiated CNS abnormalities. The pattern of regional abnormalities is related to clinical symptoms, with negative symptoms being associated with left temporal lobe rather than frontal lobe abnormality. This is consistent with suggestions of a temporolimbic prefrontal network abnormality in schizophrenia. Further longitudinal studies are warranted, using higher-resolution MRI technology and gray matter-white matter segmentation to confirm and extend these findings.

Emotional processing in schizophrenia: neurobehavioral probes in relation to psychopathology

The application of neurobehavioral methods in functional neuroimaging can provide useful information on the neurobiology of schizophrenia. This process can be enhanced by using a standard set of procedures to construct 'neurobehavioral probes' which are suitable for functional imaging and provide reliable measures discriminating patients from healthy controls. While such probes are available for cognitive tasks, none has been applied to study emotional processing in schizophrenia. We examined emotional discrimination and experience probes and correlated performance with cognitive and clinical measures. Emotion discrimination tasks and mood induction procedures with happy, sad, and neutral facial expressions were administered to 40 patients with schizophrenia. Neuropsychological testing assessed intellectual, attention, abstraction-flexibility, memory, language, spatial, and sensory-motor functions. Emotional performance was compared to a group of 40 normal subjects. Performance for face discrimination was impaired in patients. There was specific impairment in discrimination of happy expressions. Mood induction was effective in both groups, but diminished in patients, especially for happiness. Poorer performance in emotion discrimination correlated with severity of negative symptoms and bizarre behavior. Hallucinations were associated with more pronounced mood induction effects. Emotion discrimination was also correlated with abstraction, memory, language and spatial tasks, while mood induction effects showed no such associations. Thus, the impairment in discriminating and experiencing valence-specific emotions in schizophrenia relates to symptomatology and neuropsychological functioning. The results encourage the use of the emotion discrimination task and the mood induction procedure as neurobehavioral probes in physiologic neuroimaging studies for investigating the neural substrates of emotion.

Resting cerebral glucose metabolism in first-episode and previously treated patients with schizophrenia relates to clinical features

BACKGROUND

Functional neuroimaging can elucidate brain dysfunction in schizophrenia. The frontal, temporolimbic, and diencephalic regions have been implicated. There is a lack of prospective samples of first-episode and previously treated patients followed up longitudinally.

METHODS

Patients and controls (42 per group) were studied. Positron emission tomography with flurodeoxyglucose, cross-registered with magnetic resonance imaging, measured metabolism. Scales assessed clinical features, premorbid adjustment, and outcome.

RESULTS

There were no differences between groups in whole-brain metabolism or regional ratios or in anterior-posterior gradients, but left midtemporal metabolism was relatively higher in patients. This was pronounced in the negative and Schneiderian and absent in the paranoid subtypes. Higher metabolism and lower relative left hemispheric values were associated with better premorbid adjustment and outcome. A higher subcortical-cortical gradient was noted in first-episode patients.

CONCLUSIONS

There are no resting metabolic abnormalities in any brain region, but abnormal gradients are evident. These vary in subtypes, and laterality is associated with functioning. The results support the hypothesis of temporolimbic disturbance in schizophrenia that is all ready present at the onset of illness.

Sex differences in aging of the human frontal and temporal lobes

This study investigated effects of age and sex on regional brain structure in humans, focusing on the frontal and temporal lobes. Hemispheric volumes were obtained from magnetic resonance images (MRIs) of 96 young (53 men, 43 women; aged 18-40 years) and 34 older (17 men, 17 women; aged 41-80) healthy volunteers. Images (5 mm axial spin-echo, repetition time of 3000 msec and echo times of 30 and 80 msec) were resliced along the anterior commissure-posterior commissure (AC-PC) axis to standardize for difference in head tilt, and imported into a computer program where borders of the frontal and temporal lobes were delineated. The program calculated regional brain volumes based on slice data from which CSF was segmented out. An age x sex x hemisphere x region interaction indicated that age-related reductions in brain volume were sexually dimorphic, lateralized, and region specific. Greater decrements in brain volume occurred with age in the frontal lobe than in the temporal lobe. Age-related reductions in both regions were greater in men than in women, demonstrating that sexual dimorphisms in human neuroanatomy are not fixed, but continue to change throughout adulthood. The possibility that gonadal hormones play a role in the promotion and/or prevention of neural atrophy with aging is discussed.

Magnetic resonance imaging in schizophrenia: relationship with clinical measures

Relationships were examined between clinical features of schizophrenia and cerebrospinal fluid (CSF) volume in brain obtained by magnetic resonance imaging (MRI) in a sample of 59 patients. The volumes of the cerebral hemispheres and CSF were measured with a computer program designed to separate reliably neural tissue from CSF. The CSF to cranial volume ratios were related to history, symptom profile and outcome functioning. Earlier age of onset was associated with higher sulcal CSF ratio, r = -0.40. The anatomic measures were unrelated to symptom severity. However, patient subtypes differed in the laterality of measures. Higher left hemispheric ratios were seen in patients with severe negative symptoms, and left predominance of ventricular relative to sulcal ratios was associated with the presence of hallucinations and delusions. The results suggest that while higher CSF is related to earlier age of onset, the clinical symptoms are more related to its lateralization. This is consistent with the hypothesis that schizophrenia is a lateralized brain disease.

Clinical subtypes of schizophrenia: differences in brain and CSF volume

OBJECTIVE

Investigations of the relation of clinical features of schizophrenia to neuroanatomic measures have produced inconclusive results. The purpose of this study was to examine measures of whole-brain volume in men and women and relate them to clinical subtypes of schizophrenia.

METHOD

Magnetic resonance imaging measures of cranial, brain, and ventricular and sulcal CSF volume were examined in 81 patients with schizophrenia (50 men and 31 women), divided into subgroups based on their symptom profiles, and 81 demographically matched healthy comparison subjects.

RESULTS

The men had higher cranial and brain volumes than the women. The patients had smaller cranial and brain volumes than the comparison subjects; they also had higher ventricular CSF volumes and thus higher ventricle-brain ratios (VBRs). Ratio elevations were larger for the female than for the male schizophrenic patients. The patients with predominantly negative symptoms of schizophrenia had higher VBRs and sulcal CSF-brains ratios than the comparison subjects, although the component volumes did not differ. The patients with predominantly Schneiderian symptoms had higher VBRs than the comparison subjects but showed reduced cranial and brain volumes. The paranoid patients had normal VBRs, reduced sulcal CSF-brain ratios, and lower cranial and sulcal CSF volumes.

CONCLUSIONS

The results suggest two patterns of neuroanatomic whole-brain abnormalities that differ in severity according to the relative prominence of negative, Schneiderian, and paranoid symptoms. These patterns may reflect differential involvement of dysgenic and atrophic pathophysiological processes. Sex moderates abnormalities in the neuroanatomic features of schizophrenia.

Neuropsychological deficits in neuroleptic naive patients with first-episode schizophrenia

BACKGROUND

Medication and chronicity have complicated past attempts to characterize the neuropsychological performance of patients with schizophrenia. There have been inconsistencies regarding the pattern, selectivity, and sources of observed deficits. Our objective was to comprehensively examine neuropsychological function in patients with schizophrenia who had never been exposed to neuroleptic medication, and who were experiencing their first episode (FE) of psychosis.

METHODS

Subjects were consecutive recruitments that included 37 patients with FE schizophrenia who were never exposed to neuroleptics. These subjects were compared with 65 unmedicated, previously treated (PT) patients and 131 healthy controls.

RESULTS

The patients groups had nearly identical profiles showing generalized impairment, particularly in verbal memory and learning, attention-vigilance, and speeded visual-motor processing and attention. Verbal memory and learning accounted for most of the variance between patients and controls and removing this effect substantially attenuated all other differences. By contrast, both the FE group and PT group continued to show highly significant deficits in verbal memory and learning after controlling for attention, abstraction, and all other functions. Some functions not typically implicated in schizophrenia (spatial cognition, fine motor speed, and visual memory) were more impaired in the PT group than in the FE group.

CONCLUSIONS

Verbal memory, as a primary neuropsychological deficit present early in the course of schizophrenia, implicates the left temporal-hippocampal system. Neuropsychological evaluations before treatment permit differentiation of primary deficits from changes secondary to medication or chronicity. This is essential for developing a neurobehavioral perspective on schizophrenia.

Cerebral blood flow in schizophrenia: effects of memory processing on regional activation

Regional cerebral blood flow (rCBF) was measured with the 133Xenon clearance technique and a high resolution (254 detectors) scanner during the performance of a verbal and a facial memory task in 18 patients with schizophrenia and 18 sociodemographically matched controls. Patients and controls had comparable resting rCBF, but differed in global and hemispheric rCBF changes induced by the memory tasks. Patients had less global increase, which was relatively higher in the left hemisphere, and this was more pronounced for the verbal task. Although controls showed appropriate laterality changes (L > R for verbal and R > L for facial memory) in the midtemporal region, patients failed to show such a focal pattern. They did not show appropriate laterality change in the midtemporal region, but instead showed such changes in other regions. Patients showed greatest impairment in specificity of verbal recognition performance, and this correlated with severity of hallucinations and delusions. This supports a model of left temporal lobe dysfunction in schizophrenia.

Gender differences in the clinical expression of schizophrenia

Gender differences have been reported for a variety of clinical measures in patients with schizophrenia. Clinical characterization may be helpful in identifying symptom clusters which can then be linked to underlying brain function. In this study 74 men and 33 women meeting DSM-IIIR criteria for schizophrenia were studied off medication and rated on measures of symptom type and severity, as well as premorbid and current function. Men were more severely impaired in ratings of negative symptoms, while positive symptoms were not significantly different. There were also differences in premorbid and current functioning, with women manifesting better social functioning than men.

Facial emotion discrimination: III. Behavioral findings in schizophrenia

Emotional discrimination was studied in patients with schizophrenia (n = 20) and matched controls. Performance of the emotion-discrimination tasks in the schizophrenic patients was impaired, relative to their performance of an age-discrimination task. Performance patterns in the patient group could also be reliably distinguished from those of normal controls. The impairment was associated with the severity of both emotional and nonemotional symptoms specific to schizophrenia, but not with the severity of nonspecific symptoms. The deficit associated with schizophrenia is more marked than that reported for depression (Gur et al., 1992), particularly for the emotion-discrimination tasks, and showed no difference between "happy" discrimination and "sad" discrimination. The main difficulty in patients with schizophrenia is the assignment of emotional valence to neutral faces. The magnitude of the deficit underscores the salience of emotional impairment in schizophrenia, and its relation to cognitive dysfunction in this disorder merits further scrutiny.

Phenomenology and functioning in first-episode schizophrenia

One current view of schizophrenia is that its clinical and functional features show a deteriorating course, particularly for negative symptoms. However, this is difficult to study in chronic patients who have been exposed to pharmacologic treatment and institutionalization. Examining first-episode (FE) patients can help clarify which symptoms are present initially and how the symptom pattern is linked to functioning. We evaluated a sample of 37 FE patients with schizophrenia and compared them to 70 other schizophrenia (OS) patients on standard clinical scales, measures of premorbid functioning, and quality of life. FE patients showed a symptom profile similar to OS patients; in particular, there was no evidence that negative symptoms are less severe in the FE group. Analysis of the clinical data led us to the conclusion that the symptom profile of schizophrenia exists at the outset, that negative symptoms are associated with poor premorbid and current functioning, but that the role of positive symptoms is more complex and may vary in subtypes.

Volunteers for biomedical research. Recruitment and screening of normal controls

We examined the process of accruing healthy control subjects for biomedical research on brain function. Of 1670 responders to newspaper advertising, 23.1% were uninterested when learning more about the studies, and 50.9% of those remaining were found by structured telephone screening to meet exclusionary criteria for having a history of psychiatric, neurologic, or medical disease that might affect brain function. Of 312 volunteers passing the telephone screening who came to an in-person evaluation by a physician and agreed to participate, 49.7% were found to meet exclusionary criteria, and only 157 were admitted to the study. This underscores the importance of attending to the issue of screening and assessment of "normal volunteers." Alternative strategies should be considered for enriching the pool.
