RESUMO

Adolescents experiment with risk behaviors, including delinquency, substance use, and sexual activity. Multi-level social factors, such as having high-risk peers, neighborhood risks, and parental monitoring, influence adolescents' behaviors. We modeled transition patterns in Bahamian adolescents' risk behaviors across three high school years and examined the effects of multi-level factors. We collected data from 2,564 Bahamian adolescents in Grade 10 and follow-ups through Grade 12. We used latent transition model to identify adolescents' risk statuses. Further analyses used multinomial logistic regression to explore the effects of multi-level factors on assignment to those latent statuses and transitions. We identified four distinct statuses: "low risk" (47.9% of the sample at baseline), "alcohol use" (36.8%), "alcohol use and sexual activity" (5.5%), and "high risk" (9.8%). Males were more likely to be in higher-risk statuses at baseline and to transition from a lower-risk status in Grade 10 to a higher-risk status in Grade 11. Social risk factors were significantly associated with higher-risk statuses at baseline. Neighborhood risk and peer risk involvement continued to affect transitions from lower to higher risk; parental monitoring did not have a significant effect in later years. Our findings have important implications for developing targeted and developmentally appropriate interventions to prevent and reduce risk behaviors among middle-to-late adolescents.

RESUMO

BACKGROUND: African American emerging adults tend to have low adherence to asthma controller medication, as well as a disproportionate burden of asthma morbidity and mortality. This study explored constructs from the Information-Motivation-Behavioral Skills model as predictors of controller medication adherence in urban African Americans ages 18-29 (N=152) with uncontrolled asthma using multiple measures of self-reported adherence. METHODS: Structural equation modeling (SEM) was employed to test the hypothesized mediation model that specified the relationship among psychological distress, substance use, asthma knowledge, motivation, self-efficacy, and adherence. RESULTS: Results suggested that motivation is an important predictor of adherence to medication; moreover, higher self-efficacy was associated with higher motivation. Results also highlighted psychological distress as an important intervention target to improve medication adherence in emerging adults. CONCLUSIONS: The model tested in this study may offer a feasible framework for beginning to understand adherence to controller medication in this population.

RESUMO

African American emerging adults (age 18-29 years) tend to have poor asthma outcomes, possibly due to poor adherence to medication. Few studies have explored barriers to controller adherence in this population. This study utilized electronic daily diaries to assess barriers to adherence and asthma symptoms among 141 African American emerging adults with uncontrolled persistent asthma and poor adherence. Participants reported symptoms M = 3.43 days (of 7 days). They reported unintentional (e.g., forgetting) and intentional (e.g., choosing not to take) barriers to adherence, but forgetting, being too busy, and sleeping through a dose were the most common. Significant correlations were found between symptoms and barriers, as well as asthma control and medication adherence in the expected directions. Asthma symptoms and number of barriers were significant predictors of asthma control. Existing intervention strategies such as text-messaging may prove effective to address these barriers, but measuring and addressing adherence remains complex.

RESUMO

BACKGROUND: This study included Community Health Workers and their supervisors from HIV clinical care teams who participated in the Healthy Choices intervention program. Healthy Choices is a Motivational Interviewing-based intervention aimed at improving medication adherence and reducing alcohol use for adolescents and emerging adults ages 16-24 living with HIV. In this study, the intervention was "scaled up" for delivery by local HIV care providers in real-world clinic settings. METHODS: Providers (N = 21) completed semi-structured interviews (N = 29) about their experiences with intervention scale-up. Rigorous thematic analyses were conducted within discussions of barriers and facilitators of intervention implementation. RESULTS: Three dominant thematic areas emerged from the data: (1) perceptions of the Healthy Choices intervention, (2) engaging high risk YLH in in-person behavior interventions, and (3) perspectives on implementation of the intervention using local staff. Results offer insights into implementation of MI-based interventions for adolescents and emerging adults in clinic settings using local clinical staff instead of dedicated research staff. CONCLUSIONS: Overall, scaled-up intervention programs for youth are challenged to maintain scientific rigor, provide rigorous training and supports, and offer an attractive and engaging program.

RESUMO

Importance: Youth living with HIV make up one-quarter of new infections and have high rates of risk behaviors but are significantly understudied. Effectiveness trials in real-world settings are needed to inform program delivery. Objective: To compare the effectiveness of the Healthy Choices intervention delivered in a home or community setting vs a medical clinic. Design, Setting, and Participants: This randomized clinical trial was conducted from November 1, 2014, to January 31, 2018, with 52 weeks of follow-up. Participants, recruited from 5 adolescent HIV clinics in the United States, were youths and young adults living with HIV aged 16 to 24 years who were fluent in English, were currently prescribed HIV medication, had a detectable viral load, and had used alcohol in the past 12 weeks. Individuals with an active psychosis that resulted in an inability to complete questionnaires were excluded. Data were analyzed from May to December, 2019. Interventions: Participants were randomized to receive the Healthy Choices intervention in either a home or clinic setting. Four 30-minute individual sessions based on motivational interviewing to improve (1) medication adherence and (2) drinking behavior were delivered during 10 weeks by trained community health workers. In session 1, participants chose which behavior to discuss first. Using motivational interviewing strategies, the community health worker elicited motivational language, guided the development of an individualized change plan while supporting autonomy, delivered feedback, and addressed knowledge gaps. Session 2 focused on the second target behavior. In subsequent sessions, community health workers reviewed the individualized change plan, monitored progress, guided problem solving, and helped maintain changes made. Main Outcomes and Measures: Primary outcomes were viral load and alcohol use change trajectories during 52 weeks of follow-up. Alcohol use severity and frequency were measured using the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) (scores range from 0 to 33, with higher scores indicating greater severity of alcohol-related problems) and number of drinks consumed each day over a 30-day period, with timeline followback. Results: A total of 183 young people living with HIV (145 male [79.2%]; mean [SD] age, 21.4 [1.9] y) were randomized to the home setting (n = 90) or clinical setting (n = 93). Using growth-curve analysis, both groups showed declines in viral load after the intervention: among participants with available viral load information, in the home group, 12 participants (21%) had an undetectable viral load at 16 weeks, 12 (22%) at 28 weeks, and 10 (20%) at 52 weeks; in the clinic group, 16 participants (24%) had an undetectable viral load at 16 weeks, 20 (39%) at 28 weeks, and 18 (35%) at 52 weeks. However, the clinic group maintained gains, whereas those counseled at home had a significantly different and increasing trajectory during follow-up (unstandardized ß = -0.07; 95% CI,-0.14 to -0.01; P = .02). A similar pattern was observed in ASSIST scores during follow-up, with reduced ASSIST scores in the clinic group (unstandardized ß = -0.44; 95% CI,-0.81 to -0.07; P = .02). Conclusions and Relevance: In this trial, the Healthy Choices intervention resulted in improvements in viral load and alcohol use over 12 months. Unexpectedly, the clinic setting outperformed home-based delivery for viral suppression. Although cross-sectional differences in ASSIST scores were nonsignificant, clinic delivery did improve the trajectory of ASSIST scores during follow-up. Thus, clinics may be the more effective site for interventions aimed at viral load reduction for young people living with HIV. Trial Registration: ClinicalTrials.gov Identifier: NCT01969461.

RESUMO

BACKGROUND: Sustained implementation of school-based prevention programs is low. Effective strategies are needed to enhance both high-level implementation fidelity and sustainability of prevention programs. OBJECTIVE: This proposed study aims to determine if the provision of either biweekly monitoring and feedback and site-based assistance and mentorship or both to at-risk and moderate-performing teachers with monitoring through an enhanced decision-making platform by the Ministry of Education (MOE) and Ministry of Health (MOH) based on the real-time implementation data will increase national implementation fidelity and result in sustained implementation over time. METHODS: This study will target government schools including 200 grade 6 teachers in 80 primary schools and 100 junior/middle high school teachers (and their classes) on 12 Bahamian islands. Teacher and school coordinator training will be conducted by the MOE in year 1, followed by an optimization trial among teachers in the capital island. Informed by these results, an implementation intervention will be conducted to train using different levels of educational intensity all at-risk and moderate-performing teachers. Subsequently selected training and implementation strategies will be evaluated for the national implementation of Focus on Youth in the Caribbean and Caribbean Informed Parents and Children Together in years 2 to 5. RESULTS: It is hypothesized that a more intensive training and supervision program for at-risk and moderate-performing teachers will enhance their implementation fidelity to the average level of the high-performing group (85%), an HIV prevention program delivered at the national level can be implemented with fidelity in grade 6 and sustained over time (monitored annually), and student outcomes will continue to be highly correlated with implementation fidelity and be sustained over time (assessed annually through grade 9). The proposed study is funded by the National Institute of Child Health and Human Development from August 1, 2018, through May 31, 2023. CONCLUSIONS: The study will explore several theory-driven implementation strategies to increase sustained teacher implementation fidelity and thereby increase the general public health impact of evidence-based interventions. The proposed project has potential to make significant contributions to advancing school-based HIV prevention research and implementation science and serve as a global model for the Fast Track strategy.

RESUMO

Youth living with HIV (YLWH; aged 16-24) are at elevated risk of alcohol and drug use. Studies in older populations have identified patterns or profiles of multiple substance use differentially associated with mental health and anti-retroviral therapy (ART) adherence. No studies of YLWH have yet examined such patterns. A sample of 179 YLWH, reporting ART non-adherence and alcohol use, were recruited at five Adolescent Trials Network clinics in urban areas of the US between November 2014 and August 2017. Participants completed the Alcohol Smoking and Substance Involvement Screening Test (ASSIST) to assess substance use involvement scores, and the Brief Symptom Inventory. Latent Profile Analysis identified three substance use patterns: minimal illicit drug use (15.1%), cannabis only (56.4%), and global polysubstance use (28.5%). Global polysubstance users experienced more mental health problems compared to the minimal illicit drug use group. The co-occurrence of drug use with alcohol was common among these YLWH-all of whom reported ART adherence problems-indicating the importance of interventions capable of addressing multiple substance use rather than alcohol alone.

RESUMO

Objective: The goal of the current study was to determine how a set of social cognitive factors predict antiretroviral therapy (ART) medication adherence in youth living with HIV in an era of newer highly active ART medications using a conceptual model. Methods: Behaviorally infected youth living with HIV ages 13-24 (N = 822) from 14 sites within the Adolescent Medicine Trials Unit (AMTU) were included in the study. Structural equation modeling was used to explore predictors of ART medication adherence. Results: Results found that motivational readiness for ART was related to higher ART medication adherence, which was associated with lower viral load. Higher social support and higher self-efficacy had an indirect relationship with higher adherence through increased motivational readiness. Fewer psychological symptoms were associated with higher social support and higher self-efficacy. Lower substance use was directly associated with lower adherence. Conclusions: The results provide insight into factors that may be related to adherence in youth living with HIV. Findings suggest focusing on motivational readiness to increase adherence. Improving the patients' ART self-efficacy and strengthening their social support networks during treatment can increase motivational readiness for ART treatment. Furthermore, programs maybe more effective with the inclusion of risk reduction components especially those related to substance use.

RESUMO

This study examined the relationships between youth and parental sensation-seeking, peer influence, parental monitoring and youth risk involvement in adolescence using structural equation modeling. Beginning in grade-six, longitudinal data were collected from 543 students over three years. Youth sensation-seeking in grade six contributed to risk involvement in early adolescence (grades six and seven) indirectly through increased peer risk influence and decreased parental monitoring but did not have a direct contribution. It contributed directly and indirectly to risk involvement in middle adolescence (grades eight and nine). Parent sensation-seeking at baseline was positively associated with peer risk influence and negatively associated with parental monitoring; it had no direct effect on adolescent risk involvement. Parental monitoring buffers negative peer influence on adolescent risk involvement. Results highlight the need for intervention efforts to provide normative feedback about adolescent risky behaviors and to vary among families in which parents and/or youth have high sensation-seeking propensities.

RESUMO

To address global questions regarding the timing of HIV-prevention efforts targeting youth and the possible additional benefits of parental participation, researchers from the USA and The Bahamas conducted two sequential longitudinal, randomized trials of an evidence-based intervention spanning the adolescent years. The first trial involved 1360 grade-6 students and their parents with three years of follow-up and the second 2564 grade-10 students and their parents with two years of follow-up. Through grade-12, involvement in the combined child and parent-child HIV-risk reduction interventions resulted in increased consistent condom-use, abstinence/protected sex, condom-use skills and parent-child communication about sex. Receipt of the grade-6 HIV-prevention intervention conferred lasting benefits regarding condom-use skills and self-efficacy. Youth who had not received the grade-six intervention experienced significantly greater improvement over baseline as a result of the grade-10 intervention. The HIV-risk reduction intervention delivered in either or both grade-6 and grade-10 conferred sustained benefits; receipt of both interventions appears to confer additional benefits.

RESUMO

Dramatic changes occur in abstract reasoning, physical maturation, familial relationships and risk exposure during adolescence. It is probable that delivery of behavioral interventions addressing decision-making during the pre-adolescent period and later in adolescence would result in different impacts. We evaluated the intervention effects of an HIV prevention program (Bahamian Focus on Older Youth, BFOOY) administered to grade 10 Bahamian youth and parents to target HIV protective and risk behaviors. We also examined the effects of prior exposure to a similar intervention (Focus on Youth in the Caribbean, FOYC) four years earlier. At six months post-intervention, receipt of BFOOY by youth unexposed to FOYC increased HIV knowledge and condom-use skills. Differences based on BFOOY exposure were not present among FOYC-exposed youth, whose knowledge and condom-use skills were already higher than those of unexposed youth. Youth receiving both interventions displayed a carryover effect from FOYC, demonstrating the highest scores six months post-intervention.

RESUMO

The inclusion of parents in adolescent-targeted interventions is intended to benefit the adolescent. Limited research has explored whether parents participating in these programs also benefit directly. We examined the impact of Caribbean Informed Parents and Children Together, the parenting portion of an adolescent-targeted HIV prevention intervention, on parent-reported measures. Bahamian parent-youth dyads (N = 1,833) participating in the randomized control trial were assigned to receive one of four conditions. Parents were assessed longitudinally at baseline and 6 and 12 months later. Through 12 months follow-up, parents exposed to Caribbean Informed Parents and Children Together showed higher knowledge of condom use skills, perceptions of improved condom use competence on the part of their youth, and perceived improved parent-child communication about sex-related information. Although youth were the targeted beneficiary, parents also benefited directly from the sexual risk reduction parenting program. Parents demonstrated improved perceptions and knowledge that would enable them to more effectively guide their child and also protect themselves from sexual risk.

RESUMO

OBJECTIVES: We (1) evaluated the impact of an evidence-based HIV prevention program with and without a parent component among mid-adolescents living in the Caribbean and (2) determined the effect of prior receipt of a related intervention during preadolescence on intervention response. METHODS: A randomized, controlled 4-cell trial of a 10-session, theory-based HIV prevention intervention involving 2564 Bahamian grade-10 youths (some of whom had received a comparable intervention in grade 6) was conducted (2008-2011). Randomization occurred at the level of the classroom with follow-up at 6, 12, and 18 months after intervention. The 3 experimental conditions all included the youths' curriculum and either a youth-parent intervention emphasizing adolescent-parent communication, a parent-only goal-setting intervention, or no parent intervention. RESULTS: An intervention delivered to mid-adolescents in combination with a parent-adolescent sexual-risk communication intervention increased HIV/AIDS knowledge, condom-use skills, and self-efficacy and had a marginal effect on consistent condom use. Regardless of prior exposure to a similar intervention as preadolescents, youths benefited from receipt of the intervention. CONCLUSIONS: Preadolescents and mid-adolescents in HIV-affected countries should receive HIV prevention interventions that include parental participation.

RESUMO

PURPOSE: Age of the target audience at time of intervention is thought to be a critical variable influencing the effectiveness of adolescent sexual risk reduction interventions. Despite this postulated importance, to date, studies have not been designed to enable a direct comparison of outcomes according to age at the time of intervention delivery. METHODS: We examined outcomes of 598 youth who were sequentially involved in two randomized controlled trials of sexual risk prevention interventions, the first one delivered in grade 6 (Focus on Youth in the Caribbean [FOYC]) and the second one in grade 10 (Bahamian Focus on Older Youth [BFOOY]). Four groups were examined, including those who received (1) both treatment conditions, FOYC and BFOOY; (2) FOYC in grade 6 and the control condition in grade 10; (3) the control condition in grade 6 and BFOOY in grade 10; and (4) both control conditions. Intentions, perceptions, condom-use skills, and HIV-related knowledge were assessed over 60 months. RESULTS: Data showed that those who received both interventions had the greatest increase in condom-use skills. Youth who received FOYC in grade 6 had greater scores in knowledge and intention. CONCLUSION: These results suggest that youth receive the most protection with early and repeated exposure to interventions. These findings suggest that educators should consider implementing HIV prevention and risk reduction programs as a fixed component of education curriculum beginning in the preadolescent years and if possible also during the adolescent years.

RESUMO

Limited data are available as to what happens in institutions involved in behavioral intervention trials after the trial has ended. Specifically, do the trainers continue to administer the behavioral intervention that had been the focus of the trial? To address this question, we examined data in grade six schools before a year-long behavioral intervention had been delivered in some schools (and a year-long control condition in others) and data obtained again 6 and 7 years later in the same two sets of schools. Data were derived from the baseline surveys of two interventions: (1) national implementation of the evidence-based Focus on Youth in the Caribbean (FOYC) intervention in 2011; and (2) the randomized, controlled trial of the FOYC intervention in 2004/2005. Cross-sectional, longitudinal comparisons and random coefficient regression analysis were conducted to evaluate long-term intervention effects. Results indicate that grade six students in 2011 from schools in which the FOYC intervention had been implemented in 2004/2005 had a higher level of HIV/AIDS knowledge, increased reproductive health skills, increased self-efficacy regarding their ability to prevent HIV infection, and greater intention to use protection if they were to have sex compared to their counterparts from schools where no such training took place. We concluded that new cohorts of students benefited from the extensive training and/or experience in teaching the FOYC curriculum received by teachers, guidance counselors and administrators in schools which had delivered the FOYC intervention as part of a randomized trial several years earlier. The findings suggest that teachers who previously were trained to deliver the FOYC intervention may continue to teach at least some portions of the curriculum to subsequent classes of students attending these schools.

RESUMO

International behavioral research requires instruments that are not culturally-biased to assess sensation seeking. In this study we described a culturally adapted version of the Brief Sensation Seeking Scale for Chinese (BSSS-C) and its psychometric characteristics. The adapted scale was assessed using an adult sample (n=238) with diverse educational and residential backgrounds. The BSSS-C (Cronbach alpha=0.90) was correlated with the original Brief Sensation Seeking Scale (r = 0.85, p<0.01) and fitted the four-factor model well (CFI=0.98, SRMR=0.03). The scale scores significantly predicted intention to and actual engagement in a number of health risk behaviors, including alcohol consumption, cigarette smoking, and sexual risk behaviors. In conclusion, the BSSS-C has adequate reliability and validity, supporting its utility in China and potential in other developing countries.

RESUMO

This study assesses potential predictive factors for unresponsiveness to the "Focus on Youth in the Caribbean (FOYC)" intervention using longitudinal data from 1,360 Bahamian sixth-grade youth. Results from hierarchical logistic regression analyses indicate that the intervention had a greater impact on knowledge, skills, self-efficacy, and condom use intention among low and medium initial scorers. High initial scores in knowledge, skills, self-efficacy, and intention were predictive of relative unresponsiveness to the intervention. Advanced age and male sex were predictive of unresponsiveness to the intervention for HIV/AIDS knowledge. Female gender was predictive of unresponsiveness to the intervention for self-efficacy. High academic self-evaluation was predictive of unresponsiveness to the intervention for condom use intention. The greatest intervention impact was observed at the 6-month post-intervention follow-up; these intervention-related gains were sustained over the subsequent follow-up periods. Youth with higher risk attributes (lower knowledge, skills and self-efficacy) were more likely to respond to a risk reduction intervention.

RESUMO

The present study randomly assigned 15 Bahamian elementary schools to one of three intervention conditions. To assess the adequacy of cluster randomization, we examined two concerns identified by the local research team: inequality of gender distribution and environmental risk among groups. Baseline significant differences in risk and protective behaviors were minimal. There were significantly more males in the intervention group. Males had higher rates of risk behavior at all assessments. Poor school performance was also higher among the intervention condition and was significantly associated with increased rates of many but not all risk behaviors. Prior to adjusting for gender and school performance, several risk behaviors appeared to be higher after intervention among intervention youth. Adjusting for gender and school performance eradicated the group differences in risk behavior rates. Results demonstrate the importance of adequate randomization where outcomes of interest are rare events at baseline or differ by gender and there is an unequal gender distribution and the importance of the local research team's knowledge of potential inequalities in environmental risk (i.e., school performance). Not considering such individual differences could impact the integrity of trial outcomes.

RESUMO

This research evaluates condom-use self-efficacy and its increase throughout adolescence. Documentation of the development of condom-use self-efficacy would be important for prevention efforts given the influence of self-efficacy on actual condom-usage. This study assesses a hypothesized mediation mechanism of the development of self-efficacy using a mediation analysis approach. The participants, 497 grade-6 Bahamian students, were randomly assigned to the control condition in a 3-year longitudinal HIV prevention program trial. Condom-use self-efficacy consistently increased and condom-use self-efficacy assessed at earlier periods was positively associated with its values at subsequent periods. Additionally, self-efficacy assessed between two time points one year apart or longer (e.g., 6 months between baseline and 12 months) significantly mediated the impact of its levels at the previous assessment on the level at the subsequent assessment.

RESUMO

Adolescent involvement in risk behaviors is a concern that crosses geographical and cultural boundaries. Research has identified a number of factors which influence child behavior outcomes. This study explored the role of perceived neighborhood problems, parent-child relationships and parental monitoring, as they relate to engagement in risk behaviors among a sample of 497 Bahamian early adolescents. Contrary to the hypothesized direction, results of the latent growth model showed an increase in perceived parental monitoring over the four year period. Consistent with our hypotheses, adolescents who reported greater monitoring reported less involvement in sexual activity, less involvement in physical fights and less alcohol consumption. Positive interactions between parent and child also significantly predicted the initial status and rate of change of parental monitoring.
