Role of team dynamics in the learning process: a mixed-methods evaluation of a modified team-based learning approach in a behavioral research methods course.

Health sciences education is increasingly focusing on building students' skills to work collaboratively. Therefore, instructors must intentionally incorporate team-based skill building into their courses, using teaching strategies like team-based learning (TBL). An assumption of TBL is that team dynamics facilitate learning; however, limited research has examined this connection. The primary purposes of this mixed-methods evaluation were: (a) to describe the characteristics of team dynamics in a graduate-level research methods course that employs a modified TBL approach, and (b) to examine the association between team dynamics and student grades. Given the importance of preparing health professional students to work collaboratively in their careers, a secondary aim was to examine how team skills developed through a team-based learning approach could be transferred to other courses and to future jobs. We conducted surveys on team dynamics at mid-semester (n = 64) and the end of the semester (n = 66), collected students' grades for the final paper and overall course, and conducted 4 focus groups with Master of Public Health students (n = 25). Paired t tests were used to examine change in team dynamics and correlations were conducted to assess the relationship between team dynamics and grades. Thematic analysis was used to identify themes related to team dynamics from the focus group data. Overall, students reported experiencing positive and beneficial team dynamics. The findings support two main underlying categories of team dynamics, interpersonal team processes and task orientation, and the linkages between the categories that allow teams to function. Team dynamics scores were not associated with student grades. However, students recognized the value of practicing team skills in preparation for future group work and jobs. These findings suggest that active learning approaches, such as TBL, can help to facilitate the acquisition of collaborative skills.

Allowing cigarette or marijuana smoking in the home and car: prevalence and correlates in a young adult sample.

Given the increased marijuana use, negative health consequences of marijuana secondhand smoke exposure (SHSe) and dearth of research regarding marijuana SHSe in personal settings, we examined the prevalence and correlates of allowing marijuana versus cigarette smoking in personal settings among 2002 online survey respondents at two southeastern US universities in 2013. Findings indicated that 14.5% allowed cigarettes in the home, 17.0% marijuana in the home, 35.9% cigarettes in cars and 27.3% marijuana in cars. Allowing cigarettes in the home was associated with younger age, racial/ethnic minority status, living off campus, personal marijuana use, parental tobacco use and positive perceptions of cigarettes (P < 0.05). Correlates of allowing marijuana in the home included older age, not having children, living off campus, positive perceptions of marijuana and personal, parental and friend marijuana use (P < 0.05). Correlates of allowing cigarettes in cars included personal cigarette and marijuana use, parental tobacco and marijuana use, more cigarette-smoking friends and positive perceptions of cigarettes (P < 0.05). Correlates of allowing marijuana in cars included being non-Hispanic black; positive perceptions of marijuana; and personal, parental and friend marijuana use (P < 0.05). Interventions must target distinct factors influencing policies regarding cigarette versus marijuana use in personal settings to address the consequences of marijuana and cigarette SHSe.

Gender based violence as a risk factor for HIV-associated risk behaviors among female sex workers in Armenia.

This cross-sectional study identified the prevalence of gender based violence (GBV) and examined its association with sexual risk behavior among female sex workers (FSWs). Among 120 participants between ages 20 and 52, a total of 56.7 % reported lifetime GBV. Multivariate analyses revealed that GBV was significantly associated with inconsistent condom use, unprotected sex, condom misuse, fear of client reaction to requests of condom use, self-reported history of STIs, and earlier age of initiation of sex work. GBV must be considered an urgent public health priority among FSWs in Armenia. Interventions addressing FSWs, in addition to targeting skill-based, sexual risk reduction must also introduce a discourse among FSWs, sexual partners, clients and community members about the role of GBV in HIV-associated risk behaviors and infection. Structural level initiatives must address economic opportunities for women, health-sector policies and responses to FSWs' health needs, law enforcement training and societal norms toward women.

Multi-level factors associated with pregnancy among urban adolescent women seeking psychological services.

The purpose of this study was to examine the prevalence of pregnancy as well as multi-level factors (i.e., individual, family, and environment) associated with history of pregnancy among a sample of urban adolescent women seeking psychological services. Data were collected from a total of 264 sexually active, 13-18-year-old, adolescent women who participated in a larger HIV prevention study. Adolescents and one participating parent completed an audio computer-assisted self-interviewing survey. A total of 17.4% of participants reported a history of pregnancy. A multivariable logistic regression model suggests that after controlling for empirically derived sociodemographic and behavioral covariates, absence of father in the home, family support and cohesion, and neighborhood risk were positively related to pregnancy. This study is among the first to examine multi-level factors associated with pregnancy among adolescent women diagnosed with psychological disorders. Consideration of such factors is crucial both in terms of clinical practice and in the design of pregnancy prevention programs. Collaboration between physicians and mental health providers working with adolescent women is crucial and represents an ideal opportunity to promote parental involvement and access to supportive community resources, including pregnancy prevention programs for this vulnerable population of adolescents.

Behavioral and Socioemotional Outcomes of the Legacy for Children™ Randomized Control Trial to Promote Healthy Development of Children Living in Poverty, 4 to 6 Years Postintervention.

OBJECTIVE: The objective of this article was to assess the impact on behavioral and socioemotional development, 4 to 6 years postintervention (depending on the curriculum), of Legacy for Children™, a public health approach to improve child developmental outcomes among families living in poverty. METHODS: Mothers who were recruited prenatally or at the time of childbirth participated in a set of Legacy parallel design randomized control trials between 2001 and 2009 in Miami, Florida, or Los Angeles, California. Of the initial 574 mother-child dyads, 364 completed at least 1 behavioral or socioemotional outcome measure at the third-grade follow-up. Intention-to-treat analyses compared Legacy and comparison groups on behavioral and socioemotional outcomes. RESULTS: Children of Legacy mothers in Los Angeles were at lower risk for externalizing behaviors and poor adaptive skills than children whose mothers did not participate in the intervention. No significant outcome differences by group assignment were found in Miami. CONCLUSION: Group-based positive parenting interventions such as Legacy may have a sustained impact on children's behavioral and socioemotional development several years after intervention completion.

Efficacy of a health educator-delivered HIV prevention intervention for Latina women: a randomized controlled trial.

OBJECTIVES: We developed and assessed AMIGAS (Amigas, Mujeres Latinas, Inform andonos, Gui andonos, y Apoy andonos contra el SIDA [friends, Latina women, informing each other, guiding each other, and supporting each other against AIDS]), a culturally congruent HIV prevention intervention for Latina women adapted from SiSTA (Sistas Informing Sistas about Topics on AIDS), an intervention for African American women. METHODS: We recruited 252 Latina women aged 18 to 35 years in Miami, Florida, in 2008 to 2009 and randomized them to the 4-session AMIGAS intervention or a 1-session health intervention. Participants completed audio computer-assisted self-interviews at baseline and follow-up. RESULTS: Over the 6-month follow-up, AMIGAS participants reported more consistent condom use during the past 90 (adjusted odds ratio [AOR] = 4.81; P < .001) and 30 (AOR = 3.14; P < .001) days and at last sexual encounter (AOR = 2.76; P < .001), and a higher mean percentage condom use during the past 90 (relative change = 55.7%; P < .001) and 30 (relative change = 43.8%; P < .001) days than did comparison participants. AMIGAS participants reported fewer traditional views of gender roles (P = .008), greater self-efficacy for negotiating safer sex (P < .001), greater feelings of power in relationships (P = .02), greater self-efficacy for using condoms (P < .001), and greater HIV knowledge (P = .009) and perceived fewer barriers to using condoms (P < .001). CONCLUSIONS: Our results support the efficacy of this linguistically and culturally adapted HIV intervention among ethnically diverse, predominantly foreign-born Latina women.

Determinants of multimethod contraceptive use in a sample of adolescent women diagnosed with psychological disorders.

OBJECTIVE: Despite recommendations for concurrent use of contraceptives and condoms to prevent unintended pregnancy and STIs, multimethod contraceptive use among women is poor. This study examined individual-, interpersonal-, and environmental-level factors that predict multimethod use among sexually active adolescent women diagnosed with psychological disorders. METHODS: This multisite study analyzed data from 288 sexually active adolescent women who provided sociodemographic, psychosocial, and behavioral data related to birth control and condom use. RESULTS: 34.7% of the participants reported multimethod use in the past three months. Controlling for empirically and theoretically relevant covariates, a multivariable logistic regression identified self-efficacy, multiple partners, pregnancy history, parental communication, parental norms about sex, and neighborhood cohesion as significant predictors of multimethod use. CONCLUSIONS: While continued targeted messages about multi-method contraceptive use are imperative at the individual level, an uptake in messages targeting interpersonal- and environmental-level factors such as adolescents' parents and the broader community is urgently needed.

Application of condoms on male clients by female sex workers in Yerevan, Armenia: prevalence and correlates.

This study sought to assess the prevalence of consistent condom application on male clients by female sex workers (FSWs) in Armenia and its association with demographic, psychosocial and behavioural factors. In this cross-sectional study, 120 street-based FSWs aged 20-52 completed an interviewer-administered questionnaire. The primary outcome measure was consistent application of condoms by FSWs on their male clients. A total of 21.7% of participants reported consistently applying condoms on clients. Logistic regression analysis demonstrated that higher condom use self-efficacy (Adjusted Odds Ratio, AOR=1.1; p=0.01), lower perceived condom use barriers (AOR=0.9; p=0.04) and not using douching as a method to prevent STI/HIV (AOR=4.8; p=0.04) significantly predicted consistent condom application. Higher HIV/AIDS knowledge was a marginally significant predictor of condom application (AOR=1.3; p=0.05). Future interventions should address these modifiable factors to encourage FSWs to apply condoms on clients themselves, which may reduce condom failure and exposure to HIV transmission.

A randomized controlled trial of an HIV prevention intervention for street-based female sex workers in Yerevan, Armenia: preliminary evidence of efficacy.

This study evaluated the efficacy of an HIV intervention among female sex workers (FSWs) randomized to an intervention or wait-list control. FSWs (N = 120) completed baseline, 3- and 6-month assessments. A health educator implemented 2-hour intervention emphasized gender-empowerment, self-efficacy to persuade clients to use condoms, condom application skills, and eroticizing safer sex. Over the 6-month follow-up, FSWs in the intervention reported more consistent condom use with clients (P = .004) and were more likely to apply condoms on clients (P = .0001). Intervention effects were observed for other psychosocial mediators of safer sex. Brief, gender and culturally congruent interventions can enhance HIV-preventive behaviors among FSWs.

Balancing rigor against the inherent limitations of investigating hard-to-reach populations.

Maintaining rigor in research is critical; however, this need must be balanced by the necessity of conducting studies in populations where inherent barriers exist relative to key issues such as recruitment, attrition, sampling, sample size, assessment techniques, psychometric rigor, the identification of mediators and moderators and the practical relevance of the research question itself. Ultimately, the value of a study in health promotion should be judged on the practicality of the research question within the context of the target population. Striking the perfect balance between rigor and practicality to the field is a question that health promotion researchers and professionals need to determine through ongoing dialogue and debate.

Applying ecological perspectives to adolescent sexual health in the United States: rhetoric or reality?

This study sought to determine the perspective taken toward understanding adolescent sexual risk behaviors and related biological outcomes (i.e. pregnancy, sexually transmitted diseases) since 1990. We content analyzed 324 abstracts representing observational research published between January 1990 and December 2007 for inclusion of ecological (environmental) factors, level of analysis, sample composition and type of behavioral and biological outcomes. A majority (95%) of studies included individual characteristics; half were void of any environmental factors. Of those including environmental factors, 27% included familial, 23% community, 13% relational and 3% societal factors. Most (80%) were positioned at the individual level of analysis. Samples were diverse (43%) and of mixed gender (71%). Biomarkers of sexually transmitted diseases (7.5%) or pregnancy outcomes (2%) were rare. Ecological inclusion was not related to year of publication. Despite the rhetoric highlighting, the importance of an ecological perspective in understanding adolescent sexual risk behavior, much published research, excludes environmental influences.

Neighborhood environment, sexual risk behaviors and acquisition of sexually transmitted infections among adolescents diagnosed with psychological disorders.

The association between neighborhood environment and prevalence of STIs, sexual partner variables and condom use among adolescents with psychological disorders was examined. Cross-sectional data in three urban areas of the US (Southeast, Northeast and Midwest) were obtained from 384 sexually active male and female participants who provided urine samples for laboratory-confirmed testing of Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis. A total of 15.4% of participants tested positive for one of the three STIs. Results indicated that relative to adolescents living in low risk neighborhood environments, those living in high risk environments were significantly more likely to have a STI and to report having casual partners. Findings suggest that in high risk neighborhoods, STI acquisition may be less dependent on condom use and more dependent on other contextual factors. The importance of expanding public health research to include assessment of neighborhood context as a determinant of sexual risk-taking is emphasized.

Threats of cross-contamination on effects of a sexual risk reduction intervention: fact or fiction.

This study sought to empirically evaluate the extent and impact of cross-contamination on the effects of a STI/HIV intervention trial previously shown to be effective in reducing high-risk sexual behaviors among African-American adolescent females. Participants were recruited through community health agencies in the Southeastern United States and comprised 522 sexually active 14- to 18- year-old African-American females who completed self-administered questionnaires and face-to-face interviews at baseline, 6- and 12-month time points. Participants were randomized to a STI/HIV risk reduction group or a general health promotion group. The STI/HIV intervention group participated in four group sessions addressing constructs such as HIV knowledge, communication, condom use self-efficacy and condom use behaviors. The control group participated in four group sessions focused on general health topics. The study setting afforded multiple opportunities for cross-talk between intervention and control group participants. Consistent condom use, defined as condom use during every vaginal sex act, was the primary outcome measure. Other outcome measures included various sexual behaviors, observed condom application skills and psychosocial variables associated with HIV preventive behaviors. Approximately 73% of participants reported some level of cross-talk. Linear and binary GEE models assessing the impact of the STI/HIV intervention on contaminated vs. uncontaminated control group participants indicated no differential effects of the intervention. Furthermore, equivalence tests demonstrated that contaminated and uncontaminated control groups were equivalent. Findings from this study provide empirical evidence suggesting that behavioral and psychosocial outcomes may be resistant to cross-contamination in randomized controlled trials testing safer sex interventions among African-American adolescent females.

Sexual behaviors and their correlates among young people in Mauritius: a cross-sectional study.

BACKGROUND: Little is known about the HIV/AIDS epidemic in the Indian Ocean region, including Mauritius. National records suggest a prevalence of HIV in Mauritius of < 1% in the general population, which is one of the lowest prevalence rates in southern Africa. However, HIV-positive cases have been increasing recently in Mauritius. We conducted a cross-sectional survey in January 2003 to assess the prevalence of HIVrelated sexual behaviors and their correlates among young people aged 15-24 years in Mauritius. METHODS: We identified 1200 participants using two-stage cluster sampling. Demographic, social, sexual, and knowledge of HIV/AIDS data were obtained in face-to-face interviews using a structured questionnaire administered by trained interviewers. The prevalence of sexual behaviors was described in relation to gender, and the correlates of ever having had sex and nonuse of condom at last sex were analyzed using logistic regression. RESULTS: In the target population, 30.9% of males and 9.7% of females reported a history of sexual intercourse. Of the currently sexually active participants, 50.6% of men and 71.2% of women did not use condoms at their last sexual encounter. Logistic regression revealed that work experience and marijuana use were significantly associated with men's sexual experience, whereas being out of school and drinking experience were significantly associated with women's sexual experience. For both men and women, being Christian and visiting nightclubs were associated with having ever had sexual intercourse (P < 0.05). In addition, not using a condom at the first sexual encounter and lack of exposure to a nongovernmental organization (NGO) dealing with HIV/AIDS were associated with the nonuse of condoms at the last sexual encounter (P < 0.05). CONCLUSION: Young people in Mauritius are at risk of a future HIV epidemic because behaviors predisposing to HIV infection are prevalent among sexually experienced youth. A focused prevention program targeting young people should be reinforced as part of the National AIDS Control Program, taking into account the predictors of sexual behaviors identified here.

Reducing risk exposures to zero and not having multiple partners: findings that inform evidence-based practices designed to prevent STD acquisition.

Our objective was to assess prospectively the relative contribution of reducing penile-vaginal risk exposure to zero and limiting the number of sex partners to one, on the acquisition of biologically confirmed sexually transmitted disease (STD) among African American women adolescents. Data from a prospective cohort of 522 African American women adolescents enrolled in an HIV prevention trial were used. Baseline STD testing and single-dose directly observable treatment provided an infection-free cohort, who were followed and assessed at six-month intervals. Self-administered vaginal swab specimens were tested for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis at baseline, six, 12, and 18 months. Frequency of having multiple sex partners and unprotected vaginal sex over each six-month assessment interval was measured. Adolescents who reported multiple sex partners, relative to only one partner, were more likely to test positive for an STD (adjusted odds ratio (AOR) = 2.9; P = 0.0001). Adolescents who reported unprotected vaginal sex relative to those reporting protected vaginal sex also had greater odds of testing positive for an STD (AOR = 1.5; P = 0.0001). Prospective findings suggest that having multiple sex partners and engaging in unprotected vaginal sex both remain significant risk factors for STD acquisition among African American adolescent women. STD prevention programmmes need to target both risk factors to achieve optimal risk-reduction effectiveness.

Infrequent parental monitoring predicts sexually transmitted infections among low-income African American female adolescents.

OBJECTIVE: To prospectively determine (using an 18-month follow-up period) the association between African American female adolescents' perceptions of parental monitoring and their acquisition of biologically confirmed infection with Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. DESIGN: A prospective cohort study of 217 African American female adolescents enrolled in the control arm of a randomized trial of a human immunodeficiency virus prevention intervention program. SETTING AND PARTICIPANTS: A volunteer sample of adolescents (aged 14-18 years) recruited from low-income neighborhoods characterized by high rates of unemployment, substance abuse, violence, and sexually transmitted diseases. MAIN OUTCOME MEASURES: Adolescents provided 2 self-collected vaginal swab specimens. One was tested for C. trachomatis and N. gonorrhoeae DNA with ligase chain reaction. The other was used to inoculate culture medium for T. vaginalis. Identical assay procedures were repeated at the 6-month, 12-month, and 18-month follow-up intervals. RESULTS: Adjusted odds ratios indicated that adolescents who perceived infrequent parental monitoring at baseline were 1.8 (95% confidence interval, 1.01-3.21) and 2.4 (95% confidence interval, 1.22-4.87) times more likely to acquire chlamydia or trichomoniasis, respectively, compared with their counterparts who perceived greater levels of monitoring. Similarly, adolescents who perceived infrequent parental monitoring were 2.1 (95% confidence interval, 1.16-3.74) times more likely to test positive for a sexually transmitted infection during the course of the 18-month follow-up period. CONCLUSIONS: Adolescents' perceptions of their parental-monitoring levels predicted subsequent acquisition of biologically confirmed chlamydia and trichomoniasis infections. These findings suggest that expanded efforts leading toward effective clinic- and community-based sexually transmitted infection intervention programs involving parents may be warranted.

Efficacy of an HIV prevention intervention for African American adolescent girls: a randomized controlled trial.

CONTEXT: African American adolescent girls are at high risk for human immunodeficiency virus (HIV) infection, but interventions specifically designed for this population have not reduced HIV risk behaviors. OBJECTIVE: To evaluate the efficacy of an intervention to reduce sexual risk behaviors, sexually transmitted diseases (STDs), and pregnancy and enhance mediators of HIV-preventive behaviors. DESIGN, SETTING, AND PARTICIPANTS: Randomized controlled trial of 522 sexually experienced African American girls aged 14 to 18 years screened from December 1996 through April 1999 at 4 community health agencies. Participants completed a self-administered questionnaire and an interview, demonstrated condom application skills, and provided specimens for STD testing. Outcome assessments were made at 6- and 12-month follow-up. INTERVENTION: All participants received four 4-hour group sessions. The intervention emphasized ethnic and gender pride, HIV knowledge, communication, condom use skills, and healthy relationships. The comparison condition emphasized exercise and nutrition. MAIN OUTCOME MEASURES: The primary outcome measure was consistent condom use, defined as condom use during every episode of vaginal intercourse; other outcome measures were sexual behaviors, observed condom application skills, incident STD infection, self-reported pregnancy, and mediators of HIV-preventive behaviors. RESULTS: Relative to the comparison condition, participants in the intervention reported using condoms more consistently in the 30 days preceding the 6-month assessment (unadjusted analysis, intervention, 75.3% vs comparison, 58.2%) and the 12-month assessment (unadjusted analysis, intervention, 73.3% vs comparison, 56.5%) and over the entire 12-month period (adjusted odds ratio, 2.01; 95% confidence interval [CI], 1.28-3.17; P =.003). Participants in the intervention reported using condoms more consistently in the 6 months preceding the 6-month assessment (unadjusted analysis, intervention, 61.3% vs comparison, 42.6%), at the 12-month assessment (unadjusted analysis, intervention, 58.1% vs comparison, 45.3%), and over the entire 12-month period (adjusted odds ratio, 2.30; 95% CI, 1.51-3.50; P<.001). Using generalized estimating equation analyses over the 12-month follow-up, adolescents in the intervention were more likely to use a condom at last intercourse, less likely to have a new vaginal sex partner in the past 30 days, and more likely to apply condoms to sex partners and had better condom application skills, a higher percentage of condom-protected sex acts, fewer unprotected vaginal sex acts, and higher scores on measures of mediators. Promising effects were also observed for chlamydia infections and self-reported pregnancy. CONCLUSION: Interventions for African American adolescent girls that are gender-tailored and culturally congruent can enhance HIV-preventive behaviors, skills, and mediators and may reduce pregnancy and chlamydia infection.

The role of social support in the psychological well-being of African American girls who experience dating violence victimization.

The goals of this study were to test the relationship between dating violence victimization (i.e., verbal, emotional, and physical abuse) and psychological well-being (i.e., depressive symptomatology, self-esteem, and body image) among 522 African American girls, and to determine whether social support acted as a buffer of negative effects (moderator) or as an intervening factor (mediator) in the relationship between dating violence victimization and psychological well-being. Results from structural equation modeling indicated that dating violence victimization was associated with negative psychological outcomes. Although social support did not moderate this relationship, it served as a mediator of the relationship between dating violence victimization and psychological well-being. Dating violence programs for African American girls should consider how to incorporate family, church, and other networks in the community to foster support, and allow adolescent girls to discuss their abusive experiences in a nonblaming environment. If programs are able to buoy girls who experience dating violence, then they may be able to ameliorate the associated negative psychological sequelae.
