AMP! (Arts-based, Multiple component, Peer-education) is an HIV intervention developed for high school adolescents. AMP! uses interactive theater-based scenarios developed by trained college undergraduates to deliver messages addressing HIV/STI prevention strategies, healthy relationships, and stigma reduction towards people living with HIV/AIDS. We used a pre-test/post-test, control group study design to simultaneously assess intervention effect on ninth grade students in an urban county in California (N = 159) and a suburban county in North Carolina (N = 317). In each location, the control group received standard health education curricula delivered by teachers; the intervention group received AMP! in addition to standard health education curricula. Structural equation modeling was used to determine intervention effects. The post-test sample was 46 % male, 90 % self-identified as heterosexual, 32 % reported receiving free or reduced lunch, and 49 % White. Structural models indicated that participation in AMP! predicted higher scores on HIV knowledge (p = 0.05), HIV awareness (p = 0.01), and HIV attitudes (p = 0.05) at the post-test. Latent means comparison analyses revealed post-test scores were significantly higher than pre-test scores on HIV knowledge (p = 0.001), HIV awareness (p = 0.001), and HIV attitudes (p = 0.001). Further analyses indicated that scores rose for both groups, but the post-test scores of intervention participants were significantly higher than controls (HIV knowledge (p = 0.01), HIV awareness (p = 0.01), and HIV attitudes (p = 0.05)). Thus, AMP!'s theater-based approach shows promise for addressing multiple adolescent risk factors and attitudes concerning HIV in school settings.

ObjectivesThis research sought to assess racial and socioeconomic status (SES) differences in level and change in allostatic load (AL) over time in midlife women and to test whether psychosocial factors mediate these relationships. These factors were discrimination, perceived stress, and hostility.MethodsLongitudinal data obtained from the Study of Women's Health Across the Nation were used (n = 2063; mean age at baseline = 46.0 years). Latent growth curve models evaluated the impact of demographic, menopausal, and psychosocial variables on level and change in AL for 8 years.ResultsDirect effects: high levels of discrimination and hostility significantly predicted higher AL (path coefficients = 0.05 and 0.05, respectively). High perceived stress significantly predicted a faster rate of increase of AL (path coefficient = 0.06). Racial and SES differentials were present, with African American race (path coefficient = 0.23), low income (path coefficient = -0.15), and low education (path coefficient = -0.08) significantly predicting high AL level. Indirect effects: significant indirect effects were found for African American race, less income, and lower education through higher discrimination, perceived stress, and hostility on level and rate of AL.ConclusionsThis was one of the first studies that investigated AL over multiple periods, and results supported AL as a cumulative phenomenon, affected by multiple psychosocial and demographic factors. The results suggest the complex ways in which race, SES, and psychosocial factors operate to influence AL.

The current study focuses on the relationships among a trauma history, a substance use history, chronic homelessness, and the mediating role of recent emotional distress in predicting drug treatment participation among adult homeless people. We explored the predictors of participation in substance abuse treatment because enrolling and retaining clients in substance abuse treatment programs is always a challenge particularly among homeless people. Participants were 853 homeless adults from Los Angeles, California. Using structural equation models, findings indicated that trauma history, substance use history and chronicity of homelessness were associated, and were significant predictors of greater recent emotional distress. The most notable result was that recent emotional distress predicted less participation in current substance abuse treatment (both formal and self-help) whereas a substance use history alone predicted significantly more participation in treatment. Implications concerning treatment engagement and difficulties in obtaining appropriate dual-diagnosis services for homeless mentally distressed individuals are discussed.

Homeless urbanites are a heterogeneous population with unique health and social service needs. The study examined situational, behavioral, health-related and resource indicators in terms of their direct impact on frailty, hypothesized as a latent variable. Using structural equation modeling (SEM), a model was tested with 150 homeless men and women, ages 40–73, from three homeless day center drop-in sites on Skid Row and one residential drug treatment (RDT) facility that works with homeless parolees and probationers. In bivariate analyses with the latent construct frailty, months homeless (p < 0.01), female gender (p < 0.05), education (p < 0.05), comorbid conditions (p < 0.001), nutrition (p < 0.001), resilience (p < 0.001), health care utilization (p < 0.01), and falls (p < 0.001) were significantly associated with frailty. In the final path model, significant predictors of frailty included educational attainment (p < 0.01), comorbid conditions (p < 0.001), nutrition (p < 0.001), resilience (p < 0.001), and falls (p < 0.01). These findings will serve as a foundation for future nurse-led, community-based initiatives that focus on key predictors of frailty among the homeless and the development of interventions.

Homeless adults have high rates of hepatitis C virus infection (HCV) and low levels of HCV knowledge. This study reports results of an interdisciplinary, community-based intervention using stakeholder cooperation, case management, risk factor identification, and modification of dysfunctional psychosocial factors to increase HCV knowledge among homeless adults (N = 747). Data are from a randomized quasi-experimental study, with the major goal of evaluating the effectiveness of a Nurse Case Managed Intervention compared to a Standard Intervention, encouraging completion of a three-series hepatitis A/hepatitis B vaccination program. Increased HCV knowledge was measured with an 18-item questionnaire discerning risk factors for HCV and common misconceptions about individuals with HCV. A significant increase in HCV knowledge resulted regardless of intervention format. Receiving the Nurse Case Managed Intervention predicted greatest gain in HCV knowledge (p

ObjectiveIn 1993-1994, a psychosocial intervention conducted in New York City significantly improved outcomes for parents living with HIV and their adolescent children over six years. We examine if the intervention benefits are similar for adolescents of mothers living with HIV (MLH) in 2004-2005 in Los Angeles when MLH's survival had increased substantially.MethodsAdolescents of MLH in Los Angeles (N = 256) aged 12-20 years old were randomized with their MLH to either: 1) a standard care condition (n = 120 adolescent-MLH dyads); or 2) an intervention condition consisting of small group activities to build coping skills (n = 136 adolescent-MLH dyads, 78% attended the intervention). At 18 months, 94.7% of adolescents were reassessed. Longitudinal structural equation modeling examined if intervention participation impacted adolescents' relationships with parents and their sexual risk behaviors.ResultsCompared to the standard care, adolescents in the intervention condition reported significantly more positive family bonds 18 months later. Greater participation by MLH predicted fewer family conflicts, and was indirectly associated with less adolescent sexual risk behavior at the 18 month follow-up assessment. Anticipated developmental patterns were observed--sexual risk acts increased with age. Reports were also consistent with anticipated gender roles; girls reported better bonds with their mothers at 18 months, compared to boys.ConclusionsAdolescents of MLH have better bonds with their mothers as a function of participating in a coping skills intervention and reduced sexual risk-taking as a function of MLH intervention involvement.

BackgroundOnly a minority of individuals who have substance use disorders receives treatment, and those who do typically have more severe disorders. The current study examines the relationship of help-seeking with remission from alcohol and/or drug dependence and other outcomes.MethodsData from the Wave 1 (2001-2002) and Wave 2 (2004-2005) National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were used to examine remission at Wave 2 among respondents who had past-year substance dependence disorders at Wave 1 (N=1262). Multi-group structural equation modeling was used to compare individuals with (n=356) and without (n=906) prior help-seeking at Wave 1 on subsequent help-seeking and other factors that influence outcomes.ResultsBaseline help-seekers sought help at higher levels over the follow-up period (31% vs. 8%) and had lower rates of remission (50% vs. 68%), as compared with those without prior help-seeking, respectively. Among baseline help-seekers, there were stronger relationships between baseline stress and mental disorders and having sought help since baseline; age and past-year level of stress at follow-up; level of stress and health status at follow-up; and social support and mental disorders at follow-up. Among baseline non-help-seekers, there were stronger relationships between being female and past-year stress at follow-up, and between having sought help since baseline and physical health status at follow-up.ConclusionsFindings extend our understanding of the factors associated with recovery from substance dependence, including "natural recovery", use of services outside of addiction treatment, and gender differences in help-seeking and remission.

PurposePrevious work suggests that opioid users have lower health-related quality of life (HRQOL) than patients with more prevalent chronic illnesses such as hypertension or diabetes. Although comparisons with population norms are informative, studies of the correlates of HRQOL for opioid users are needed to plan clinical services.MethodsWe tested a conceptual model of the pathways between physiologic factors and symptoms in relation to HRQOL among 344 opioid users in a clinical trial. Physical and mental HRQOL were measured by the Short-Form (SF)-36; withdrawal signs, symptoms, and functioning were also measured with validated instruments. Using structural equation modeling, we tested hypotheses that medical history directly predicts withdrawal signs and symptoms, and that medical history, withdrawal signs and symptoms, and functioning predict the physical and mental HRQOL latent variables of the SF-36.ResultsMost hypothesized relationships were significant, and model fit was good. The model explained 36% of the variance in mental HRQOL and 34% of the variance in physical HRQOL.ConclusionsThe conceptual framework appears valid for explaining variation in the physical and mental HRQOL of opioid users undergoing medically managed withdrawal. Analysis of longitudinal data would help to evaluate more rigorously the adequacy of the model for explaining HRQOL in opioid withdrawal.

Family and social relationships are important structural supports in Thailand that are likely to influence the health and mental health of persons living with HIV (PLH). Structural equation modeling examined these relationships among 409 PLH in two communities in Thailand. Latent variables were constructed for most outcomes and mediators, with adherence to antiretroviral (ARV) therapy, depression, and disclosure represented by single-item indicators. All models controlled for gender, age, and education. Disclosure was significantly and positively associated with ARV adherence, and to both family functioning and social support. Family functioning and social support were significantly related to the PLH's self-perceptions of health and mental health, as well as being significantly correlated with each other. Better family functioning was significantly associated with better quality of life, better perceived health, fewer symptoms of depression, and greater ARV adherence. Social support was significantly associated with better quality of life and fewer depressive symptoms. These results highlight the important role that an organized and structured family life and social support network can play in encouraging better health outcomes among PLH.

ObjectiveUnprotected sexual behavior, needle sharing, and a prison history are major correlates of hepatitis B Virus (HBV). These risk factors are common among homeless people who also have elevated rates of HBV. We examine whether these behaviors were associated with completion or loss to follow-up of the most intensive and successful condition of a 3-arm HBV vaccination intervention. Significant results would imply that those most in need are the least compliant. Contributions of baseline demographics, physical health, psychosocial variables, and health beliefs were also assessed.DesignThree-hundred thirty-one adults from Los Angeles' Skid Row were assigned to nurse-case-managed sessions with hepatitis education, incentives, and tracking. Successive predictive structural equation models assessed the amount of variance accounted for by the risk variables, demographics, and the health-related variables.Main outcome measures(1) Completion of 3 injections by 6 months; and (2) loss to a 6-month follow-up questionnaire.ResultsThe 3 risk factors explained 2% of the variance in completion and 1% of the variance in loss. Adding the other variables increased the variance explained to 14% for completion and 13% for loss. African American ethnicity, positive coping, social support, poorer health, no prison history, and greater efficacy significantly predicted completion. White ethnicity, less social support, better health, and less intention to complete predicted participant loss.ConclusionThe program was not strongly rejected differentially as a function of preexisting hepatitis B risk behaviors. Programs designed for homeless people should include malleable psychosocial and health belief model variables. These aspects of the lives of homeless people provide leverage points for future interventions.

A biopsychosocial perspective is employed to assess associations among situational and psychosocial variables related to health, health care, and HIV/AIDS risk behaviors among 479 homeless men (aged 18-64 years). Poor health was not significantly associated with sexual risk behaviors and was only modestly associated with injection drug use (IDU). Health care was not significantly associated with sexual risk behavior or IDU. HIV/AIDS risk behaviors were highly associated with homelessness severity and posttraumatic stress disorder. IDU was significantly associated with greater emotional distress and was more likely among younger men and among White men. Sexual risk behavior was more frequent among those who had particularly poor-quality housing such as living on the street or in abandoned buildings. Because interactions with the medical community are limited and not associated with HIV/AIDS risk, outreach in areas in which homeless men congregate, mental health and substance abuse treatment, and permanent supportive housing may help reduce HIV risk among homeless men more effectively.

Finding direct and indirect influences of salient psychosocial and situational variables on problem substance use among homeless people is important in designing evidence-based, effective, and relevant interventions for this special population. A stress-coping paradigm in conjunction with situational items specialized for homeless people was used to explore predictive relationships in a sample of homeless adults (N = 664) among (a) psychosocial variables of self-esteem, social support, positive and negative coping, and emotional distress, (b) situational variables of homelessness history and quality of recent housing, and (c) outcomes of alcohol use, injection drug use (IDU), and non-IDU. Lower self-esteem predicted greater emotional distress, lower positive coping, greater negative coping, and more alcohol use. Social support predicted less emotional distress and more positive coping. Chronic homelessness predicted more emotional distress, less positive coping, greater alcohol use, and IDU. Poor housing was associated with more alcohol use and IDU. Substance abuse interventions among the homeless should have a dual focus that includes attention to psychological issues and negative coping patterns while also addressing situational, environmental factors, including encouraging provision of permanent supportive housing.

ObjectiveTo assess predictors of latent tuberculosis infection (LTBI) completion by using structural equation modeling (SEM) among homeless adults, a group at great risk for LTBI and active tuberculosis (TB). LTBI therapy is effective in stemming the progression to active TB, yet treatment adherence among homeless persons is difficult to attain.DesignBy using SEM, the authors assessed predictors of LTBI completion among a sample of 494 homeless adults in Los Angeles, CA, who received either a nurse case-managed program (NCM) or a usual care program.Main outcome measuresLatent variables were created with the baseline variables of site type, age, intervention status, dissatisfaction with health care, depression, TB risk assessment, alcohol use, heroin or cocaine use, and TB knowledge. Outcome variables included many of the same baseline variables as well as treatment completion.ResultsLTBI treatment completion (100% adherence) was significantly and positively associated with participation in NCM, older age, and less heroin or cocaine use. NCM also predicted greater TB knowledge, greater ease of treatment, and more satisfaction with treatment (NCM completion rate = 64%, control rate = 42%).ConclusionThe culturally competent NCM program, combined with active tracking and incentives, was successful in a difficult-to-treat and highly transient population.

Studies among normative samples generally demonstrate a positive impact of marriage on health behaviors and other related attitudes. In this study, we examine the impact of marriage on HIV/AIDS risk behaviors and attitudes among impoverished, highly stressed, homeless couples, many with severe substance abuse problems. A multilevel analysis of 368 high-risk sexually intimate married and unmarried heterosexual couples assessed individual and couple-level effects on social support, substance use problems, HIV/AIDS knowledge, perceived HIV/AIDS risk, needle-sharing, condom use, multiple sex partners, and HIV/AIDS testing. More variance was explained in the protective and risk variables by couple-level latent variable predictors than by individual latent variable predictors, although some gender effects were found (e.g., more alcohol problems among men). The couple-level variable of marriage predicted lower perceived risk, less deviant social support, and fewer sex partners but predicted more needle-sharing.

Homeless individuals are at risk for numerous health problems including Hepatitis C virus (HCV). HCV is primarily caused by sharing of equipment associated with injection drug use (IDU). In the current study, we assessed differences among HCV-negative and HCV-positive homeless men residing in Los Angeles (N = 198; about 50% HCV positive) on a number of risk factors and behaviors. Findings revealed several significant correlates of HCV-positive status. HCV-positivity was significantly and positively associated with a history of substance use (IDU and non-IDU), recent IDU-related behaviors including equipment sharing, other forms of sharing (e.g., toothbrushes, razors), homelessness severity, tattoos, sexually transmitted diseases, a jail/prison history, and greater age. Lifetime alcohol problems were not associated with HCV. Although associations of HCV with current IDU-related behaviors are not surprising, it is alarming that these behaviors were recent. Those who work among homeless populations should be aware not only of the high likelihood of HCV infection in this population but also of the transmission risk due to continued IDU sharing behaviors. Substance abuse treatment should be implemented to hinder the spread of HCV in this vulnerable population. Also, needle exchange and provision of clean ancillary IDU equipment should be encouraged in areas where homeless people are known to congregate.

Two separate path models for alcohol and drugs were tested in which psychosocial, environmental, and sociodemographic variables predicted behavioral and substance abuse related factors as well as the key outcome of positive attitudes about quitting drugs (N = 620) or alcohol (N = 526) in a sample of 709 homeless women. A positive attitude about quitting alcohol was predicted by more Addiction Symptoms, fewer Positive Effects from using alcohol and not having a partner who uses alcohol. A positive attitude about quitting drugs was predicted by more Drug Problems, greater Drug Use in the Past 6 Months, more Active Coping, more education, less Emotional Distress, not having a partner who uses drugs, and fewer Addiction Symptoms. Implications of the results for drug and alcohol interventions are discussed.

ObjectiveThis study, using latent variable methodology, explores simultaneously the relative effects of childhood abuse and early parental substance abuse on later chronic homelessness, depression, and substance abuse problems in a sample of homeless women. We also examine whether self-esteem and recent violence can serve as mediators between the childhood predictors and the dysfunctional outcomes.MethodThe sample consists of 581 homeless women residing in shelters or sober living centers in Los Angeles (54% African-American, 23% Latina, 22% White, mean age=33.5 years). Multiple-indicator latent variables served as predictors and outcomes in structural models. Childhood abuse was indicated by sexual, physical, and verbal abuse.ResultsChildhood abuse directly predicted later physical abuse, chronic homelessness, depression, and less self-esteem. Parent substance use directly predicted later substance use problems among the women. Recent physical abuse predicted chronic homelessness, depression, and substance use problems. Greater self-esteem predicted less depression and fewer substance use problems. Childhood abuse also had significant indirect effects on depression, chronic homelessness, and drug and alcohol problems mediated through later physical abuse and self-esteem.ConclusionsAlthough there was a strong relationship between childhood abuse and parent drug use, childhood abuse was the more pervasive and devastating predictor of dysfunctional outcomes. Childhood abuse predicted a wider range of problems including lower self-esteem, more victimization, more depression, and chronic homelessness, and indirectly predicted drug and alcohol problems. The mediating roles of recent physical abuse and self-esteem suggest salient leverage points for change through empowerment training and self-esteem enhancement in homeless women.

Using a multiracial sample of 621 homeless women, we tested a latent variable causal model of personal, cognitive, behavioral, and demographic predictors of two coping mediators and the outcome variables of HIV testing and return for test results and a recent STD infection. HIV testing and return were predicted by more social support, greater AIDS knowledge, greater perceived risk for AIDS, and more problem-focused coping strategies. Recent STDs were predicted by more AIDS knowledge, emotion-focused coping strategies, and risky sexual behavior and one measured variable, crack cocaine use. Emotion-focused coping strategies were predicted by drug use, less self-esteem, more social support, and greater perceived risk for AIDS. Hispanics reported less emotion-focused coping strategies than African-Americans. Predictors of problem-focused coping strategies included less drug use, more self-esteem, more social support, more AIDS knowledge, and less risky sexual behavior. African-Americans reported less problem-focused coping strategies than Latinas. Indirect effects on the outcomes mediated through coping styles are also reported. Theoretical and practical implications of results for community outreach are discussed.

We examined risk and protective factors associated with three qualitatively different drug use constructs describing a continuum of drug use among a sample of 1,179 homeless women. Relationships among positive and negative sources of social support, positive and negative coping strategies, depression, and the drug constructs of current drug use, drug problems, and physical drug dependence were assessed using structural equation models with latent variables. Current drug use was predicted by more negative social support (from drug-using family/friends), depression, and less positive coping. Drug Problems were predicted by more negative coping, depression, and less positive coping. Physical Drug Dependence was predicted by more negative social support and depression, and less positive social support. Results highlighted the importance of investigating both the positive and negative dimensions of psychosocial functioning, while suggesting that empowering homeless women and offering tangible resources for coping with the stress of being homeless may be beneficial to them.

The present study examined a causal model consisting of personal and social resources, threat appraisal processes, coping styles, and barriers to risk reduction as predictors of general AIDS risk and specific drug use behaviors among homeless African American (N = 714) and Latina (N = 691) women. The model, which was based on a stress and coping framework, supported many of the hypothesized relationships. Active coping was associated with fewer general AIDS risk behaviors for both groups and less specific drug use behavior among African American women. Specific drug use behavior was predicted by high threat appraisal and avoidant coping for both groups. Ethnic differences and implications for intervention are discussed.
