Effects of Automatic Associative Activation on Explicit and Implicit Memory Tests

Ss made either a graphemic or a semantic decision concerning word pairs during a study phase. Pair relatedness effects were observed in behavioral measures for the semantic task only, but a physiological measure (event-related potential) showed relatedness effects for both study tasks. Relatedness at study helped subsequent memory for tests involving word generation (fragment completion and cued recall). These effects was independent of those of level of processing on memory

HIV risk factors for persons with serious mental illness

HIV risk factors were assessed among 120 persons in treatment for serious mental illness. Although subjects had good general knowledge regarding HIV, many engaged in high risk behaviors. Condom use was infrequent among those who had multiple sexual partners, and sharing needles was common for those who used IV drugs. Clearly, factual knowledge about HIV was not sufficient to prevent risky behavior. Nearly half of the sample was categorized as at medium to high risk, and almost half of the participants, especially those at medium risk, underestimated their own level of risk. The results suggest that education and intervention strategies should focus on increasing the accuracy of the individuals risk assessment as well as changing attitudes towards condoms and improving skills in using condoms. Assessing personal risk and adopting risk-reduction strategies are the keys to successful AIDS prevention for persons with serious mental illness.

Detection of Guilty Knowledge with Event-Related Potentials

The N400 component of the event-related potential (ERP) is elicited by words that complete sentence falsely. The utility of the N400 in discriminating subjects who have knowledge of a crime from those who do not was examined in this study. Post hoc analyses indicated that 78% of subjects could be correctly classified as guilty or innocent. With further development, ERPs may become useful auxiliaries to current lie-detection techniques.

Predictors of Avoidable Hospitalizations Among Assisted Living Residents

OBJECTIVES Hospitalizations for long term care residents, including those from assisted living facilities (ALFs), are very costly, often traumatic, and increase risk for iatrogenic disorders for those involved. Currently, hospital expenditures account for approximately one-third of total national health care spending. Hospitalizations for ambulatory care-sensitive (ACS) conditions are considered potentially avoidable, as these are physical health conditions that can often be treated safely at a lower level of care or occur as a result of lack of timely, adequate treatment at a lower level of care. The goal was to examine risk factors for hospitalization for an ACS condition of Medicaid-enrolled younger and older ALF residents during 2003-2008. DESIGN This is a retrospective cohort study that used 5 years of Medicaid enrollment and fee-for-service claims data. PARTICIPANTS The study sample included 16,208 Medicaid-enrolled ALF residents in Florida, 7991 (49%) of whom were 65 years of age or older. RESULTS In total, study participants had 22,114 hospitalizations, 3759 (17%) of which were for an ACS condition. Sixteen percent of all ALF residents (n = 2587), about 12% of the younger residents and 20% of the older residents, had at least one ACS hospitalization. ACS hospitalizations constitute 13% of all hospitalizations for the younger residents and 22% of all hospitalizations for the older residents. Using Cox proportional hazard regression, we found that for both age groups, increased age, being Hispanic or of other race/ethnicity, and having comorbid physical health conditions were associated with a higher risk of ACS hospitalization. For older residents, having a dementia diagnosis and being African American reduced the risk of ACS hospitalization, whereas for younger residents having a major psychotic disorder reduced the risk of ACS hospitalization. CONCLUSION The results highlight the need for increased education, communication, and future research on these predictive factors. The increased frequency of hospitalization for ACS conditions among ALF residents with minority status and older age may well indicate that their more complex health care needs are not being adequately addressed. The role of serious mental illness and dementia in risk for ACS hospitalization also deserves further attention.

Risk Factors for Early Readmission to Acute Care for Persons with Schizophrenia taking Antipsychotic Medications

OBJECTIVE The study examined risk factors for readmission to acute care among Florida Medicaid enrollees with schizophrenia treated with antipsychotics. METHODS Medicaid and service use data for 2004 to 2008 were used to identify adults with schizophrenia discharged from hospitals and crisis units who were taking antipsychotics. Data were extracted on demographic characteristics, service use before admission, psychopharmacologic treatment after discharge, and readmission to acute behavioral health care. Cox proportional hazards regression estimated readmission risk in the 30 days after discharge and in the period after 30 days for participants not readmitted in the first 30 days. RESULTS The mean±SD age of the 3,563 participants was 43.4±11.1; 61% were male, and 38% were white. Participants had 6,633 inpatient episodes; duration of hospitalization was 10.6±7.0 days. Readmission occurred for 84% of episodes, 23% within 30 days. Variables associated with an increased readmission risk in the first 30 days were shorter hospitalization (hazard ratio [HR]=1.18, 95% confidence interval [CI]=1.10-1.27, p<.001), shorter time on medication before discharge (HR=1.19, CI=1.06-1.35, p=.003), greater prehospitalization use of acute care (HR=2.64, CI=2.29-3.05, p<.001), serious general medical comorbidity (HR=1.21, CI=1.06-1.38, p=.005), and prior substance abuse treatment (HR=1.58, CI=1.37-1.83, p<.001). After 30 days, hospitalization duration and time on medication were not significant risk factors. CONCLUSIONS Short hospital stays for persons with schizophrenia may be associated with risk of early readmission, possibly because the person is insufficiently stabilized. More chronic risk factors include prior acute care, general medical comorbidity, and substance abuse.

Risk adjustment of Florida mental health outcomes data: Concepts, methods, and results

This article discusses outcome evaluation systems for mental health programs. It reviews and critically evaluates design and analysis methods for strengthening the validity of such uncontrolled comparisons. The article examines methods for statistically adjusting preexisting groups, now referred to as risk adjustment or case-mix adjustment, and offers guidelines for determining when this procedure is appropriate. Then, analyses on two dependent variables—a global rating of functioning and a consumer satisfaction measure—available from an outcomes evaluation system currently underway in Florida are used to demonstrate the proposed method of risk adjustment. Results for 24 providers of mental health services showed that while risk adjustment only made a small difference in the overall provider rankings, the ranking of some specific providers changed considerably. The article concludes with a discussion of the implications of this research.

Gender Differences and Risk of Arrest Among Offenders with Serious Mental Illness

Despite the increasing number of men and women with serious mental illness (SMI) incarcerated in Americas jails, little research exists on the role gender may play in arrest among persons with SMI. This study examined correlates of arrests among offenders with SMI, specifically the role of gender. County criminal justice records, as well as county and statewide social service archival databases, were used to identify jail inmates with SMI in a large urban county in Florida. Of the 3,769 inmates identified, 41% were female. This study identified three distinct classes of male and female offenders within which persons had similar trajectories of arrests over the 4-year study period representing those with minimal, low, and high arrest rates. Findings suggest some important differences between women and men in risk factors for re-arrests. Attention to these factors may improve the ability to prevent future recidivism among men and women with SMI.

Risk of Arrest in Persons With Schizophrenia and Bipolar Disorder in a Florida Medicaid Program: The Role of Atypical Antipsychotics, Conventional Neuroleptics, and Routine Outpatient Behavioral Health Services

OBJECTIVE To examine (1) arrest outcomes for adults with schizophrenia and bipolar disorder who were treated with first-generation antipsychotics (FGAs) or second-generation atypical antipsychotics (SGAs) and (2) the interaction between medication class and outpatient services in a Florida Medicaid program. METHOD In a secondary data analysis, Florida Medicaid data covering the period from July 1, 2002, to March 31, 2008, were used to identify persons diagnosed with schizophrenia, schizoaffective disorder, and bipolar disorder and to examine antipsychotic medication episodes lasting at least 60 days. There were 93,999 medication episodes in the population examined (N = 36,519). Medication episodes were coded as (1) SGA-aripiprazole, clozapine, olanzapine, paliperidone, quetiapine, risperidone, risperidone long-acting therapy, or ziprasidone; or (2) FGA-any other antipsychotic medication. Outpatient services were defined as the proportion of 30-day periods of each medication episode with at least 1 behavioral health visit. Survival analyses were used to analyze the data, and they were adjusted for the baseline propensity for receiving an SGA. RESULTS Second-generation antipsychotic episodes were not associated with reduced arrests compared to FGA episodes; however, the interaction between outpatient services and SGA episodes was significant (hazard ratio [HR] = 0.68; 95% CI, 0.50-0.93; P = .02) such that an SGA episode with an outpatient visit during at least 80% of every 30-day period of the episode was associated with reduced arrests compared to SGA episodes with fewer outpatient services. There was no significant effect for concurrent FGA episodes and outpatient treatment (HR = 0.81; 95% CI, 0.60-1.10; P = .18). Substance use, poor refill compliance, and prior arrest increased risk of subsequent arrest. CONCLUSIONS The interaction between outpatient visits and treatment with SGAs was significantly associated with reduced arrests. These findings indicate the importance of concurrent antipsychotic medications and outpatient services to affect arrest outcomes for adults with schizophrenia and bipolar disorder.

Assisting clients of community mental health centers to secure SSI benefits: a controlled evaluation.

The entire caseloads of three Community Mental Health Centers were screened on variables normally assessed in the SSI application process. These data were then used to classify each individual as Possibly Eligible for SSI benefits, or as Probably Not Eligible. The Possibly Eligible subjects were randomly assigned to either the Experimental condition, in which subjects were helped to apply for SSI, or the Control condition, in which no intervention was provided. Results showed that the Experimental subjects were almost twice as likely to secure SSI benefits as the Control subjects. The usefulness of the screening form was supported in that control subjects were almost five times more likely to be awarded SSI, compared with subjects who had been classified as Probably Not Eligible.

Factors related to criminal justice expenditure trajectories for adults with serious mental illness

BACKGROUND Criminal careers have been extensively studied in general population sample, but less is known about such patterns among people with major mental illness, and where so, criminal justice expenditure has not been taken into account. AIMS Our aim was to examine criminal justice system expenditure over time in one Florida county. Our main research question was whether treatment for mental disorders was related to a change in criminal offending and expenditure trajectory. METHODS We used the Pinellas County (Florida) Criminal Justice Information System to identify individuals under age 65 arrested between July 2003 and June 2004. Archival medical service, social and homeless services data were used to identify individuals with a serious mental illness. A two-step analysis was used to examine the data: first, we identified groups of people with similar patterns of criminal justice expenditures over 4 years (July 2002 to June 2006); second, we evaluated their demographic characteristics, diagnosis and treatment as potential predictors of group membership. RESULTS Three thousand seven hundred sixty-nine people with serious mental illness were identified in the Pinellas County jail population. Their average length of stay in jail was 151 days and in prison was 48 days. The trajectory analysis identified three groups of individuals with distinct trajectories of criminal justice expenditures: those with low stable, those with initially high but decreasing and those with initially high and sustained or increasing. Mental health treatment, whether acute or sustained, voluntary or mandatory, was associated with membership of the low stable group. CONCLUSION Review of criminal justice expenditure over time on individuals with major mental disorder may provide important indicators of unmet need for mental health services. Furthermore, it seems probable that improved provision of such services for them could reduce recidivism as well as improving health. Interventions may also be better focused if criminal justice expenditure trajectories are examined; programmes targeting re-offending as well as specific mental health problems may be most effective.
