RESUMO

The Family Resource Scale (FRS) is a three-factor financial vulnerability (FV) measure. FV may impact HIV transmission risks. Cross-sectional data from 279 people who inject drugs (PWID) in Kyrgyzstan surveyed April-October 2021 was used to validate the FRS and estimate associations between FV on past 6-month injection and sexual HIV risk outcomes. The three-factor FRS reflected housing, essential needs, and fiscal independence, and had good internal reliability and structural validity. Greater cumulative, housing, and essential needs FRS scores were associated with increased relative risk on public injection (adjusted risk ratio [aRR], 95% confidence interval [95% CI]: 1.03 [1.01, 1.04]; aRR [95% CI]: 1.06 [1.02, 1.09]; aRR [95% CI]: 1.06 [1.03, 1.08], respectively, all p < 0.001) and preparing injections with unsafe water sources (aRR [95% CI]: 1.04 [1.02, 1.07]; aRR [95% CI]: 1.09 [1.04, 1.15]; aRR [95% CI]: 1.08 [1.03, 1.14], respectively, all p < 0.001). Results suggest that PWID housing- and essential needs-related FV may exacerbate injection HIV transmission risks. Reducing PWIDs' FV may enhance the HIV response in Kyrgyzstan.


RESUMEN: La Escala de Recursos Familiares (FRS, por sus siglas en inglés) es una medida de vulnerabilidad financiera (FV, por sus siglas en inglés) de tres factores. La FV puede afectar los riesgos de transmisión del VIH. Se utilizaron datos transversales de 279 personas que se inyectan drogas (PWID, por sus siglas en inglés) en Kirguistán encuestadas de abril a octubre de 2021 para validar la FRS y estimar las asociaciones entre la FV en la inyección y los resultados de riesgo sexual del VIH en los últimos seis meses. La FRS de tres factores reflejaba la vivienda, las necesidades esenciales y la independencia fiscal, y presentaba una buena confiabilidad interna y validez estructural. Mayores puntajes acumulativos de la FRS en vivienda y necesidades esenciales se asociaron con un mayor riesgo relativo en la inyección pública (Riesgo relativo ajustada [aRR], Intervalo de Confianza del 95% [IC95%]: 1.03 [1.01, 1.04]; aRR [IC95%]: 1.06 [1.02, 1.09]; aRR [IC95%]: 1.06 [1.03, 1.08], respectivamente, todos p < 0.001) y la preparación de inyección con fuentes de agua no seguras (aRR [IC95%]: 1.04 [1.02, 1.07]; aRR [IC95%]: 1.09 [1.04, 1.15]; aRR [IC95%]: 1.08 [1.03, 1.14], respectivamente, todos p < 0.001). Los resultados sugieren que la FV relacionada con la vivienda y las necesidades esenciales de las PWID puede exacerbar los riesgos de transmisión del VIH por la inyección. Reducir la FV de las PWID puede mejorar la respuesta al VIH en Kirguistán.

RESUMO

OBJECTIVES: Non-adherence to antipsychotics is the greatest obstacle to treating schizophrenia. We assessed the economic and clinical impacts of adherence to antipsychotics among people living with HIV/AIDS (PLWH) and schizophrenia in British Columbia, Canada. DESIGN AND SETTING: A population-based cohort study in British Columbia, Canada. METHODS: Eligible PLWH were enrolled in the Seek and Treat for Optimal Prevention HIV/AIDS population-based cohort during 2001-2016, diagnosed with schizophrenia, on antipsychotics for ≥1 day, and followed for ≥1 year from schizophrenia diagnosis date or 1 January 2001, whichever occurred last. PRIMARY AND SECONDARY OUTCOME MEASURES: A two-part model assessed the marginal effect of adherence on healthcare costs (in 2016 Canadian dollar), while logistic regression examined the effect on virological failure, and generalised linear mixed models examined the effect on hospital readmissions within 30 days and length of hospital stay. RESULTS: Among 726 PLWH with schizophrenia, ≥80% adherence to antipsychotics increased from 25% (50/198) in 2001 to 41% (225/554) in 2016. In most years, we observed no difference in adherence to antipsychotics among those who used only injectables, only non-injectables, and a combination of both, or among those who have ever consumed typical/first-generation antipsychotics and who consumed only atypical/second-generation antipsychotics. Overall healthcare costs were higher in the non-adherent group ($C2185), driven by the average annual hospitalisation costs ($C5517), particularly among women ($C8806) and people who ever injected drugs (PWID) ($C5985). Non-adherent individuals also experienced higher hospital readmissions (adjusted odds ratio (aOR) 1.48, 95% CI 1.23 to 1.77), and longer hospital stays (adjusted mean ratio 1.23, 95% CI 1.13 to 1.35) in comparison to adherent individuals. We found no difference in virological failure by adherence groups, except when we stratified by gender where the aOR for women was 2.48 (95% CI 1.06 to 5.82). CONCLUSIONS: Our results showed that implementing strategies and interventions to increase antipsychotic adherence, particularly among women and PWID, will be critical in addressing this public health challenge.

RESUMO

BACKGROUND AND HYPOTHESIS: Automated language analysis is becoming an increasingly popular tool in clinical research involving individuals with mental health disorders. Previous work has largely focused on using high-dimensional language features to develop diagnostic and prognostic models, but less work has been done to use linguistic output to assess downstream functional outcomes, which is critically important for clinical care. In this work, we study the relationship between automated language composites and clinical variables that characterize mental health status and functional competency using predictive modeling. STUDY DESIGN: Conversational transcripts were collected from a social skills assessment of individuals with schizophrenia (n = 141), bipolar disorder (n = 140), and healthy controls (n = 22). A set of composite language features based on a theoretical framework of speech production were extracted from each transcript and predictive models were trained. The prediction targets included clinical variables for assessment of mental health status and social and functional competency. All models were validated on a held-out test sample not accessible to the model designer. STUDY RESULTS: Our models predicted the neurocognitive composite with Pearson correlation PCC = 0.674; PANSS-positive with PCC = 0.509; PANSS-negative with PCC = 0.767; social skills composite with PCC = 0.785; functional competency composite with PCC = 0.616. Language features related to volition, affect, semantic coherence, appropriateness of response, and lexical diversity were useful for prediction of clinical variables. CONCLUSIONS: Language samples provide useful information for the prediction of a variety of clinical variables that characterize mental health status and functional competency.

RESUMO

INTRODUCTION: Performance-based assessments of social skills have detected impairments in people with severe mental illness and are correlated with functional outcomes in people with schizophrenia and bipolar disorder. The most common of these assessments, the Social Skills Performance Assessment (SSPA), has two communication scenarios and items measuring both social competence and appropriateness. As real-world competence and appropriateness appear to have different correlates, we hypothesized that SSPA Items measuring competence and appropriateness would be distinct and have different correlations with other outcomes. METHODS: We aggregated data from 557 people with schizophrenia, 106 with bipolar disorder, and 378 well controls from 4 separate research studies. All participants were assessed with both SSPA scenarios and other performance based and clinician-rated measures. A single expert rated the SSPA interactions for competence and appropriateness while blind to participant diagnoses. RESULTS: Participants with bipolar disorder and schizophrenia performed more poorly on every item of the SSPA than healthy controls. Items measuring social competence and appropriateness in communication were intercorrelated across scenarios, as were elements of socially competent communication, although the items measuring competence did not correlate substantially with appropriateness. Items assessing social competence, but not social appropriateness, correlated with better cognitive and functional performance and residential and financial independence. DISCUSSION: Social competence and social appropriateness were distinct elements of performance-based social skills with potential differences in their functional correlates. As both social competence and appropriateness impact functional outcomes, improvement in the measurement and treatment of appropriate communication seems to be an important goal.

RESUMO

Background: North Tijuana, Mexico is home to many individuals at high risk for transmitting and acquiring human immunodeficiency virus (HIV). Recently, policy shifts by local government impacted how these individuals were handled by authorities. Here we examined how this affected regional HIV transmission dynamics. Methods: HIV pol sequences and associated demographic information were collected from 8 research studies enrolling persons in Tijuana and were used to infer viral transmission patterns. To evaluate the impact of recent policy changes on HIV transmission dynamics, qualitative interviews were performed on a subset of recently infected individuals. Results: Between 2004 and 2016, 288 unique HIV pol sequences were obtained from individuals in Tijuana, including 46.4% from men who have sex with men, 42.1% from individuals reporting transactional sex, and 27.8% from persons who inject drugs (some individuals had >1 risk factor). Forty-two percent of sequences linked to at least 1 other sequence, forming 37 transmission clusters. Thirty-two individuals seroconverted during the observation period, including 8 between April and July 2016. Three of these individuals were putatively linked together. Qualitative interviews suggested changes in policing led individuals to shift locations of residence and injection drug use, leading to increased risk taking (eg, sharing needles). Conclusions: Near real-time molecular epidemiologic analyses identified a cluster of linked transmissions temporally associated with policy shifts. Interviews suggested these shifts may have led to increased risk taking among individuals at high risk for HIV acquisition. With all public policy shifts, downstream impacts need to be carefully considered, as even well-intentioned policies can have major public health consequences.

RESUMO

The UCSD Performance-Based Skills Assessment (UPSA) is a performance-based measure of functional capacity. The brief, two-domain (finance and communication ability) version of the assessment (UPSA-B) is now widely used in both clinical research and treatment trials. To date, research has not examined possible demographic-UPSA-B relationships within a non-psychiatric population. We aimed to produce and describe preliminary normative scores for the UPSA-B over a full range of ages and educational attainment. The finance and communication subscales of the UPSA were administered to 190 healthy participants in the context of three separate studies. These data were combined to examine the effects of age, sex, and educational attainment on the UPSA-B domain and total scores. Fractional polynomial regression was used to compute demographically-corrected T-scores for the UPSA-B total score, and percentile rank conversion was used for the two subscales. Age and education both had significant non-linear effects on the UPSA-B total score. The finance subscale was significantly related to both gender and years of education, whereas the communication subscale was not significantly related to any of the demographic characteristics. Demographically corrected T-scores and percentile ranks for UPSA-B scores are now available for use in clinical research.

RESUMO

Depressed mood has a complex relationship with self-evaluation of personal competence in multiple populations. The absence of depression may be associated with overestimation of abilities, while mild depression seems to lead to accurate self-assessment. Significant depression may lead to underestimation of functioning. In this study, we expand on our previous work by directly comparing the association between different levels of depression, everyday functioning, cognitive and functional capacity performance, and self-assessment of everyday functioning in a large (n = 406) sample of outpatients with schizophrenia. Participants with very low self-reported depression overestimated their everyday functioning compared with informant reports. Higher levels of depression were associated with more accurate self-assessment, but no subgroup of patients underestimated their functioning. Depressive symptom severity was associated with poorer informant-rated social functioning, but there were no differences in vocational functioning, everyday activities, cognitive performance, and functional capacity associated with the severity of self-reported depression. There was minimal evidence of impact of depression on most aspects of everyday functioning and objective test performance and a substantial relationship between depression and accuracy of self-assessment.

RESUMO

People living with HIV/AIDS (PHA) often concurrently cope with mental health disorders that may greatly influence HIV and other health-related outcomes. The objective of this study was to examine the prevalence and correlates of self-reported mental health disorder diagnosis among a cohort of harder-to-reach HIV-positive individuals in British Columbia, Canada. Between 2007 and 2010, 1000 PHA who had initiated ART were enrolled in the Longitudinal Investigation into Supportive and Ancillary health services (LISA) study. Socio-demographic, behavioral, health-care utilization and psychosocial information was collected through interviewer-led questionnaires and linked to longitudinal clinical variables through the provincial Drug Treatment Program at the BC Centre for Excellence in HIV/AIDS. We identified the prevalence of all-type and specific mental health disorders among this population. Of the 916 participants included in this analysis, 494 (54%) reported ever having a mental health disorder diagnosis. Mood (85%) and anxiety (65%) disorders were the two most frequently reported mental health conditions. Self-reported all-type mental health disorder was independently associated with decreased overall functioning (adjusted odds ratio [AOR] = 0.90, 95% confidence interval [CI] = 0.83-0.98) and life satisfaction (AOR = 0.81, 95% CI = 0.74-0.89), and having higher stigma score (AOR = 1.11, 95%CI = 1.02-1.21). Participants reporting any mental health disorder were more likely to report a history of sexual assault (AOR = 2.45, 95% CI = 1.75-3.43) and to have used case management services (AOR = 1.63, 95%CI = 1.17-2.27). Our findings uncovered a high burden of mental health disorders among harder-to-reach PHA and suggest that PHA with at least one mental health disorder diagnosis are disproportionately impacted by sexual violence and stigma.

RESUMO

The UCSD Performance-based Skills Assessment (UPSA) is a widely used measure of functional capacity with strong reliability and validity. However there is a lack of psychometric data on Hispanics. The purpose of this study was to determine the impact of acculturation and education on UPSA performance among 62 Hispanic participants with schizophrenia or schizoaffective disorder and 46 healthy comparison subjects. Functional capacity was measured using the UPSA. Acculturation was measured using the Acculturation Rating Scale for Mexican Americans (ARSMA). Independent t-tests indicated that participants with schizophrenia had significantly lower UPSA total scores and scored lower on all UPSA sub-scales relative to the comparison group. Multiple regression also indicated that education and acculturation were significant predictors of UPSA total scores. These data provide a better understanding of UPSA scores in Hispanics with and without schizophrenia, and suggest that education and acculturation adjustments may be required to improve interpretation of test results.

RESUMO

BACKGROUND: We evaluated the cost-effectiveness of combined single session brief behavioral intervention, either didactic or interactive (Mujer Mas Segura, MMS) to promote safer-sex and safer-injection practices among female sex workers who inject drugs (FSW-IDUs) in Tijuana (TJ) and Ciudad-Juarez (CJ) Mexico. Data for this analysis was obtained from a factorial RCT in 2008-2010 coinciding with expansion of needle exchange programs (NEP) in TJ, but not in CJ. METHODS: A Markov model was developed to estimate the incremental cost per quality adjusted life year gained (QALY) over a lifetime time frame among a hypothetical cohort of 1,000 FSW-IDUs comparing a less intensive didactic vs. a more intensive interactive format of the MMS, separately for safer sex and safer injection combined behavioral interventions. The costs for antiretroviral therapy was not included in the model. We applied a societal perspective, a discount rate of 3% per year and currency adjusted to US$2014. A multivariate sensitivity analysis was performed. The combined and individual components of the MMS interactive behavioral intervention were compared with the didactic formats by calculating the incremental cost-effectiveness ratios (ICER), defined as incremental unit of cost per additional health benefit (e.g., HIV/STI cases averted, QALYs) compared to the next least costly strategy. Following guidelines from the World Health Organization, a combined strategy was considered highly cost-effective if the incremental cost per QALY gained fell below the gross domestic product per capita (GDP) in Mexico (equivalent to US$10,300). FINDINGS: For CJ, the mixed intervention approach of interactive safer sex/didactic safer injection had an incremental cost-effectiveness ratio (ICER) of US$4,360 ($310-$7,200) per QALY gained compared with a dually didactic strategy. Using the dually interactive strategy had an ICER of US$5,874 ($310-$7,200) compared with the mixed approach. For TJ, the combination of interactive safer sex/didactic safer injection had an ICER of US$5,921 ($104-$9,500) per QALY compared with dually didactic. Strategies using the interactive safe injection intervention were dominated due to lack of efficacy advantage. The multivariate sensitivity analysis showed a 95% certainty that in both CJ and TJ the ICER for the mixed approach (interactive safer sex didactic safer injection intervention) was less than the GDP per capita for Mexico. The dual interactive approach met this threshold consistently in CJ, but not in TJ. INTERPRETATION: In the absence of an expanded NEP in CJ, the combined-interactive formats of the MMS behavioral intervention is highly cost-effective. In contrast, in TJ where NEP expansion suggests that improved access to sterile syringes significantly reduced injection-related risks, the interactive safer-sex combined didactic safer-injection was highly cost-effective compared with the combined didactic versions of the safer-sex and safer-injection formats of the MMS, with no added benefit from the interactive safer-injection component.

RESUMO

BACKGROUND: Globally, client-perpetrated violence against female sex workers (FSWs) has been associated with multiple health-related harms, including high-risk sexual behavior and increased exposure to HIV/STIs. This study examined correlates of client-perpetrated sexual, physical, and economic violence (e.g., robbery) against FSWs in 13 cities throughout Mexico. METHODS: FSWs (N = 1,089) who were enrolled in a brief, evidence-based, sexual risk reduction intervention for FSWs (Mujer Segura) were interviewed about their work context, including experiences of violence perpetrated by clients, sexual risk and substance use practices, financial need, and social supports. Three broad categories of factors (sociodemographic, work context, behavioral and social characteristics of FSWs) were examined as correlates of sexual, physical, and economic violence. RESULTS: The prevalence of different types of client-perpetrated violence against FSWs in the past 6 months was: sexual (11.7%), physical (11.8%), economic (16.9%), and any violence (22.6%). Greater financial need, self-identification as a street worker, and lower perceived emotional support were independently associated with all three types of violence. Alcohol use before or during sex with clients in the past month was associated with physical and sexual violence. Using drugs before or during sex with clients, injection drug use in the past month, and population size of city were associated with sexual violence only, and FSWs' alcohol use score (AUDIT-C) was associated with economic violence only. CONCLUSIONS: Correlates of client-perpetrated violence encompassed sociodemographic, work context, and behavioral and social factors, suggesting that approaches to violence prevention for FSWs must be multi-dimensional. Prevention could involve teaching FSWs strategies for risk avoidance in the workplace (e.g., avoiding use of alcohol with clients), enhancement of FSWs' community-based supports, development of interventions that deliver an anti-violence curriculum to clients, and programs to address FSWs' financial need by increasing their economic opportunities outside of the sex trade.

RESUMO

OBJECTIVE: This study examined service provider perceptions of requirements for successful sustainment of an efficacious intervention for preventing HIV/AIDS and STIs in female sex workers (FSWs) in Mexico. METHODS: Semi-structured interviews were conducted with 77 leaders and counselors from 12 community-based reproductive health clinics located throughout Mexico participating in a large hybrid effectiveness-implementation randomized controlled trial to scale-up the use of Mujer Segura, a psychoeducational intervention designed to promote condom use and enhance safer sex negotiation skills among FSWs. RESULTS: Five sets of requirements for sustainment were identified: 1) characteristics of the provider, including competence in delivering the intervention, need for continued technical support and assistance from outside experts, and satisfaction with addressing the needs of this population; 2) characteristics of the clients (i.e., FSWs), including client need and demand for services and incentives for participation; 3) characteristics of the organization, including its mission, benefits, and operations; 4) characteristics of the outer setting, including financial support and relationship with the community-based organization's central offices, and transportation and security in areas where FSWs live and work; and 5) outcomes associated with the intervention itself, including a reduction of risk through education and increased outreach through referrals from FSWs who received the intervention. CONCLUSIONS: Although the requirements for successful sustainment of interventions like Mujer Segura are consistent with the factors identified in many models of implementation, the results illustrate the importance of local context in assigning priority to these model elements and suggest that the five categories are not discrete entities but interconnected.

RESUMO

OBJECTIVE: This study aimed to develop and validate a tablet mobile application version of the UCSD Performance-Based Skills Assessment (UPSA-M), a widely used test for assessing functional capacity in schizophrenia and other neurocognitively impaired patient populations. METHODS: The UPSA-M was developed for an iPad platform. Twenty-one middle-aged and older adults with schizophrenia and 13 healthy comparison (HC) participants completed a brief iPad tutorial, followed by the UPSA-M (full version, which includes all components of Brief UPSA-M) and a computer usage questionnaire. During a separate visit, patients with schizophrenia and HC participants completed the Brief UPSA (UPSA-B), and patients with schizophrenia completed a symptom inventory and brief neuropsychological screening battery. RESULTS: The UPSA-M was feasible for use among middle aged and older adults with schizophrenia with no prior history of tablet usage. The UPSA-M was able to differentiate between schizophrenia and HC participants 80% of the time, and this differential ability increased to 87% with the UPSA-M Brief. Traditional UPSA scores, UPSA-B scores, and neuropsychological performance were related to UPSA-M scores, whereas symptoms of psychopathology, experience with tablet technology, or difficulties operating the device were not significantly associated with UPSA-M. CONCLUSIONS: The UPSA-M performed just as well as the standard-of-practice version. These preliminary results indicate that the UPSA-M Brief has greater sensitivity than the full version of the UPSA-M, and carries the advantage of a shorter administration time. Overall, the UPSA-M appears to be a promising mobile tool to assess functional capacity.

RESUMO

OBJECTIVE: Self-assessment deficits, often referred to as impaired insight or unawareness of illness, are well established in people with schizophrenia. There are multiple levels of awareness, including awareness of symptoms, functional deficits, cognitive impairments, and the ability to monitor cognitive and functional performance in an ongoing manner. The present study aimed to evaluate the comparative predictive value of each aspect of awareness on the levels of everyday functioning in people with schizophrenia. METHOD: We examined multiple aspects of self-assessment of functioning in 214 people with schizophrenia. We also collected information on everyday functioning rated by high contact clinicians and examined the importance of self-assessment for the prediction of real-world functional outcomes. The relative impact of performance-based measures of cognition, functional capacity, and metacognitive performance on everyday functioning was also examined. RESULTS: Misestimation of ability emerged as the strongest predictor of real-world functioning and exceeded the influences of cognitive performance, functional capacity performance, and performance-based assessment of metacognitive monitoring. The relative contribution of the factors other than self-assessment varied according to which domain of everyday functioning was being examined, but, in all cases, accounted for less predictive variance. CONCLUSION: These results underscore the functional impact of misestimating one's current functioning and relative level of ability. These findings are consistent with the use of insight-focused treatments and compensatory strategies designed to increase self-awareness in multiple functional domains.

RESUMO

Awareness of illness is a major factor in schizophrenia and extends into unawareness of cognitive and functional deficits. This unawareness of functional limitations has been shown to be influenced by several different predictive factors, including greater impairment and less severe depression. As treatment efforts are aimed at reducing cognitive deficits, discovery of the most efficient assessment strategies for detection of cognitive and functional changes is critical. In this study, we collected systematic assessments from high contact clinicians focusing on their impressions of the cognitive deficits and everyday functioning in a sample of 169 community dwelling patients with schizophrenia. The patients provided self-report on those same rating scales, as well as self-reporting their depression and performing an assessment of cognitive performance and functional skills. There was essentially no correlation between patients' self-reports of their cognitive performance and functional skills and either clinician ratings of these skills or the results of the performance-based assessments. In contrast, clinician reports of cognitive impairments and everyday functioning were correlated with objective performance data. Depression on the part of patients was associated with ratings of functioning that were both more impaired and more congruent with clinician impressions, while overall patients reported less impairment than clinicians. These results underscore the limitations of self-reported cognitive functioning even with structured rating scales. Concurrently, clinicians provided ratings of cognitive performance that were related to scores on objective tests, even though they were unaware of the results of those assessments.

RESUMO

Vocational functioning is markedly impaired in people with schizophrenia. In addition to low rates of employment, people with schizophrenia have been reported to be underachieved compared to other family members. Among the causes of this vocational impairment may be cognitive deficits and other skills deficits, as well as social factors impacting on opportunities for employment. In this study, we examined two separate samples of people with schizophrenia who differed in their educational and social backgrounds. We compared personal and maternal education in people with schizophrenia attending an outpatient rehabilitation facility (n = 57) or receiving outpatient services at a VA medical center (n = 39). The sample as a whole showed evidence of decline in vocational status from their best job to their most recent job. Patients attending a rehabilitation facility had completed less education than their mothers, while the VA patients completed more. Differences between personal and maternal education predicted the difference in status between best and latest jobs in the sample as a whole. VA patients were more likely to be living independently and performed better on a measure of functional capacity than the rehabilitation sample. These data implicate vocational decline in schizophrenia and also suggest that this decline may originate prior to the formal onset of the illness. At the same time, vocational outcomes appear to be related to social opportunities.

RESUMO

Caregiving for individuals with Alzheimer's disease is associated with chronic stress and elevated symptoms of depression. Placement of the care receiver (CR) into a long-term care setting may be associated with improved caregiver well-being; however, the psychological mechanisms underlying this relationship are unclear. This study evaluated whether decreases in activity restriction and increases in personal mastery mediated placement-related reductions in caregiver depressive symptoms. In a 5-year longitudinal study of 126 spousal Alzheimer's disease caregivers, we used multilevel models to evaluate placement-related changes in depressive symptoms (short form of the Center for Epidemiologic Studies Depression scale), activity restriction (Activity Restriction Scale), and personal mastery (Pearlin Mastery Scale) in 44 caregivers who placed their spouses into long-term care relative to caregivers who never placed their CRs. The Monte Carlo method for assessing mediation was used to evaluate the significance of the indirect effect of activity restriction and personal mastery on postplacement changes in depressive symptoms. Placement of the CR was associated with significant reductions in depressive symptoms and activity restriction and was also associated with increased personal mastery. Lower activity restriction and higher personal mastery were associated with reduced depressive symptoms. Furthermore, both variables significantly mediated the effect of placement on depressive symptoms. Placement-related reductions in activity restriction and increases in personal mastery are important psychological factors that help explain postplacement reductions in depressive symptoms. The implications for clinical care provided to caregivers are discussed.

RESUMO

The U.S. Latino population is steadily increasing, prompting a need for cross-cultural outcome measures in schizophrenia research. This study examined the contribution of language to functional assessment in middle-aged Latino patients with schizophrenia by comparing 29 monolingual Spanish-speakers, 29 Latino English-speakers, and 29 non-Latino English-speakers who were matched on relevant demographic variables and who completed cognitive and functional assessments in their native language. There were no statistically significant differences between groups on the four everyday functioning variables (UCSD Performance-Based Skills Assessment [UPSA], Social Skills Performance Assessment [SSPA], Medication Management Ability Assessment [MMAA], and the Global Assessment of Functioning [GAF]). The results support the cross-linguistic and cross-cultural acceptability of these functional assessment instruments. It appears that demographic variables other than language (e.g., age, education) better explain differences in functional assessment among ethnically diverse subpopulations. Considering the influence of these other factors in addition to language on functional assessments will help ensure that measures can be appropriately interpreted among the diverse residents of the United States.

RESUMO

Male clients of female sex workers (FSWs) in Tijuana, Mexico engage in high levels of unprotected sex. While behavioral change theories posit that self-efficacy predicts condom use, correlates of self-efficacy for condom use remain largely unstudied. We examined these correlates among male clients of FSWs in Tijuana. Eligible male clients were at least 18 years of age, HIV-negative, lived in Tijuana or San Diego, reported unprotected sex with a Tijuana FSW at least once in the past 4 months, and agreed to be treated for sexually transmitted infections (STIs). Participants completed an interviewer-administered questionnaire including demographics, substance use, psychosocial and psychosexual characteristics (e.g., outcome expectancies for negotiation of safer sex, social support, and sexual sensation seeking), and sexual behaviors. Participants also underwent HIV/STI testing. A stepwise hierarchical multiple regression analysis identified correlates of self-efficacy for condom use. Of 393 male clients, median age was 37 years. Participants were mostly Spanish-speaking and employed. Factors independently associated with higher self-efficacy for condom use were higher positive outcome expectancies for negotiation of safer sex, lower sexual sensation seeking scores, and higher social support scores. Both psychosocial and psychosexual factors may influence self-efficacy for condom use among male clients of FSWs. These factors represent central constructs in sociocognitive models that explain behavioral change and could be intervention targets for improving self-efficacy for condom use and, ultimately, safer sex behavior.

RESUMO

BACKGROUND: Neurocognitive impairments are the strongest predictor of functional deficits in schizophrenia, but adaptive (i.e., functional) capacity, typically measured with performance-based assessments, yields an objective index of current abilities, whereas real-world functional performance relies on observations of community activity. However, limited experiences in the community may limit the acquisition, retention, or expression of these skills. METHODS: We examined the frequency of engagement in behaviors that are assessed in the current "gold standard" in person functional capacity assessment. The UCSD Performance-Based Skills Assessment (i.e., UPSA) examines skills associated with recreational engagement, handling money, scheduling appointments, and navigating public transportation. We used neurocognition, experience, and UPSA performance as predictors of the relationships among cognition and real-world functioning variables. RESULTS: Neurocognition was a significant correlate of UPSA scores regardless of whether it was forced into the model before or after prior experience, whereas experience was only a significant predictor of UPSA scores when entered before neurocognition. Further, functional capacity, neurocognition, and experience were significant predictors of real-world outcomes and experience remained a significant predictor regardless of the order it was entered into the model. CONCLUSIONS: The amount of current experience with functional tasks is not a rate-limiter of the relationships between neurocognition and functional capacity but does account for some previously unexplained variance in the functional capacity-everyday functioning relationship. These findings underscore the importance of neurocognitive deficits as they relate to functional capacity in schizophrenia, and suggest an incremental functional cost of limited experience with independent living.
