Sexting and Sexual Behavior in At-Risk Adolescents

Christopher D. Houck; David H. Barker; Christie J. Rizzo; Evan Hancock; Alicia Norton; Larry K. Brown

OBJECTIVES: This study aimed to examine the prevalence of sexting behaviors (sexually explicit messages and/or pictures) among an at-risk sample of early adolescents as well as the associations between sexting behaviors and sexual behaviors, risk-related cognitions, and emotional regulation skills. It also aimed to determine whether differences in risk were associated with text-based versus photo-based sexts. METHODS: Seventh-grade adolescents participating in a sexual risk prevention trial for at-risk early adolescents completed a computer-based survey at baseline regarding sexting behavior (having sent sexually explicit messages and/or pictures), sexual activities, intentions to have sex, perceived approval of sexual activity, and emotional regulation skills. RESULTS: Twenty-two percent of the sample reported having sexted in the past 6 months; sexual messages were endorsed by 17% (n = 71), sexual messages and photos by 5% (n = 21). Pictures were endorsed significantly more often by females (χ2[2] = 7.33, P = .03) and Latinos (χ2[2] = 7.27, P = .03). Sexting of any kind was associated with higher rates of engaging in a variety of sexual behaviors, and sending photos was associated with higher rates of sexual activity than sending text messages only. This was true for a range of behaviors from touching genitals over clothes (odds ratio [OR] = 1.98, P = .03) to oral sex (OR = 2.66, P < .01) to vaginal sex (OR = 2.23, P < .01). CONCLUSIONS: Sexting behavior (both photo and text messages) was not uncommon among middle school youth and co-occurred with sexual behavior. These data suggest that phone behaviors, even flirtatious messages, may be an indicator of risk. Clinicians, parents, and health programs should discuss sexting with early adolescents.

Sexual Abuse and Sexual Risk Behavior: Beyond the Impact of Psychiatric Problems

Christopher D. Houck; Nicole R. Nugent; Celia M. Lescano; Annette Peters; Larry K. Brown

OBJECTIVE This study examined the association between sexual abuse (SA) and sex risk in girls and boys placed in alternative and therapeutic school settings while controlling for psychiatric problems. METHOD Adolescents were recruited from alternative and therapeutic schools. Youth completed audio computer-assisted self-interviews assessing childhood abuse, sexual behaviors, sexual attitudes, and psychiatric symptoms. RESULTS Of the 162 youth with available data, 23% reported a moderate or severe SA history. After controlling for gender and the presence of a psychiatric diagnosis, youth with a SA history were significantly more likely to have engaged in sex, had sex in the last 90 days, and engaged in unprotected sex. Adolescents with a history of SA also endorsed fewer advantages of using condoms. CONCLUSIONS SA is uniquely associated with sexual behavior and attitudes even when adjusting for the presence of a psychiatric diagnosis. These data have implications for interventions for those with SA histories.

OBJECTIVES We sought to learn what factors are associated with anal intercourse among adolescents and young adults. We examined demographic, behavioral, relationship context, attitudinal, substance use, and mental health correlates of recent heterosexual anal intercourse among adolescents and young adults who reported engaging in recent unprotected sex. METHODS Among 1348 at-risk adolescents and young adults aged 15 to 21 years in 3 US cities, we assessed sexual risk behavior with each sexual partner in the past 90 days. Data were collected from 2000 to 2001. RESULTS Recent heterosexual anal intercourse was reported by 16% of respondents. Females who engaged in anal intercourse were more likely to be living with a sexual partner, to have had 2 or more partners, and to have experienced coerced intercourse. For males, only a sexual orientation other than heterosexual was a significant predictor of engaging in heterosexual anal intercourse. CONCLUSIONS Our findings document the prevalence of heterosexual anal intercourse among adolescents and young adults who had recent unprotected sex. Among females, the variables associated with anal intercourse relate to the context and power balance of sexual relationships. Different influences for males and females suggest different foci for interventions.

Adolescent Sexual Risk: Factors Predicting Condom Use Across the Stages of Change

Cynthia I. Grossman; Wendy Hadley; Larry K. Brown; Christopher D. Houck; April Peters; Marina Tolou-Shams

This study examined factors associated with high-risk adolescents’ movement toward or away from adopting consistent condom use behavior using the Transtheoretical Model Stages of Change. Participants drawn from the inactive comparison condition of a randomized HIV prevention trial (Project SHIELD) responded to items assessing pros and cons of condom use, peer norms, condom communication, and perceived invulnerability to HIV. Participants were categorized based on their condom use behavior using the Transtheoretical Model. Multiple logistic regressions found that progression to consistent condom use was predicted by continuing to perceive more advantages to condom use, reporting greater condom use communication with partners, and less perceived invulnerability to HIV. Movement away from adopting consistent condom use was predicted by a decrease in perceived advantages to condom use, increased perceived condom disadvantages, and fewer condom discussions. Future interventions may be tailored to enhance these factors that were found to change over time.

Who Accepts a Rapid HIV Antibody Test? The Role of Race/Ethnicity and HIV Risk Behavior Among Community Adolescents

Rebecca R. Swenson; Wendy Hadley; Christopher D. Houck; S. Kwame Dance; Larry K. Brown

PURPOSE Centers for Disease Control and Prevention guidelines recommend routine human immunodeficiency virus (HIV) screening in health care settings for all individuals aged 13-64 years; however, overall testing rates among adolescents still continue to remain low. This study examined factors related to the acceptance of HIV testing among an at-risk sample of ethnically/racially diverse community adolescents. METHODS Adolescents aged 15-21 (N = 81) years were recruited from community-based youth organizations to complete HIV risk assessment surveys. After the completion of the survey, participants were offered a free OraQuick rapid HIV antibody test. RESULTS More than half (53.1%) of the participants accepted the test, with the black population being more likely to accept testing as compared to Latinos (75% vs. 39%). After controlling for race/ethnicity, significant predictors of test acceptance included history of sexual intercourse (OR = 5.43), having only one sexual partner in the past 3 months (OR = 4.88), not always using a condom with a serious partner (OR = 3.94), and not using a condom during last sexual encounter (OR = 4.75). CONCLUSION Given that many adolescents are willing to know their HIV status, policies that support free or low-cost routine testing may lead to higher rates of case identification among youth. However, approaches must be developed to increase test acceptance among Latino adolescents and teenagers with multiple sexual partners.

Suicide Attempt and Sexual Risk Behavior: Relationship among Adolescents

Christopher D. Houck; Wendy Hadley; Celia M. Lescano; David Pugatch; Larry K. Brown

The objective of this study was to examine the relationship between a history of suicide attempt and a range of current sexual risk behaviors in a large sample of sexually high-risk adolescents. Baseline data from 1,245 sexually active 15 to 21 year olds were collected as part of a multi-site, randomized trial of a brief HIV prevention program. Measures were collected using audio computer assisted self-interviews. Accounting for demographic, contextual, and substance use variables, a lifetime history of suicide attempt significantly added to multivariate regression models predicting sexual risk. Inconsistent condom users were almost twice as likely to have attempted suicide, and adolescents with an STI diagnosis were approximately twice as likely to have a history of suicide attempt. A history of suicidal behavior can be identified by clinicians and appears to be an important marker for sexual risk, which may represent an expression of emotional distress or a passive form of self-injury for suicidal adolescents.

Frequency of adolescent self-cutting as a predictor of HIV risk.

Larry K. Brown; Christopher D. Houck; Cynthia I. Grossman; Celia M. Lescano; Jennifer L. Frenkel

Objective: A wide range exists in the frequency of adolescent self-cutting behavior; however, the implications of this variability are relatively unexplored. Although evidence suggesting a relationship between self-harm and sexual risk behaviors has been identified, little is known regarding the relationship between frequency of self-cutting and sexual risk. The present study aimed to test the hypothesis that adolescents who repeatedly self-cut would report more HIV risk behaviors and riskier attitudes than those who had engaged in infrequent self-injury. Method: Adolescents (11–18 years; mean age, 15 years) from intensive psychiatric treatment programs with a history of self-cutting (N = 105, 53% female) completed measures of self-cutting, sexual risk behaviors, and risk attitudes. Results: Frequent self-cutting (more than three times, lifetime) was associated with being sexually active, using condoms inconsistently, and sharing cutting instruments. Frequent self-cutters were significantly more likely to be female and nonwhite, and report low self-restraint. They also showed a trend toward being more likely to have a history of sexual abuse. Conclusions: This study found important differences in self-cutters based on frequency of cutting. Adolescent self-cutting may be a spectrum of behavior that ranges from habitual, repeated behavior contrasted with infrequent, experimental, socially motivated cutting. The associations between frequent cutting, sexual risk, and low self-restraint suggest that common underlying mechanisms may determine these patterns.

OBJECTIVE To evaluate the effectiveness of Safe Thinking and Affect Regulation (STAR), a 14-session HIV-prevention program for adolescents at alternative/therapeutic schools. Because these youth frequently have difficulties with emotions and cognitions, it was designed to improve sexuality-specific affect management and cognitive monitoring, as well as HIV-related knowledge and attitudes. It was hypothesized that STAR would lead to a decrease in sexual risk and improved HIV knowledge and attitudes. METHOD Fourteen schools were randomly assigned by year either to the STAR intervention or a brief educational program. Schools received the alternate intervention the following year. A total of 185 adolescents in 29 cohorts (groups) participated in the interventions. Assessment of sexual behavior, knowledge and attitudes with audio computer-assisted self-interviews occurred at 3, 6, and 9 months post intervention. RESULTS Hierarchical linear model (HLM) analyses found that adolescents in the STAR intervention reported a significantly greater decrease (p < .05) in the Sexual Risk Index than youth in the control group over the 6 months post intervention and similar improvements in the HIV Knowledge Scale and the Condom Use Self Efficacy Scale. There were no group differences between 6 and 9 months post intervention. CONCLUSIONS This STAR intervention for youth in alternative schools was associated with decreased sexual risk for 6 months after the intervention. These data suggest that intervention strategies that target cognitions and affect within a sexual context might be usefully applied to improving sexual behavior but may need to be reinforced over time.

HIV prevention for juvenile drug court offenders: a randomized controlled trial focusing on affect management.

Marina Tolou-Shams; Christopher D. Houck; Selby M. Conrad; Nicholas Tarantino; L. A. R. Stein; Larry K. Brown

Juvenile drug court (JDC) offenders have benefited from evidence-based interventions addressing antisocial behavior, mental health, and substance use; however, interventions addressing HIV risk behavior are lacking. This study presents pilot findings and lessons learned from a group-based HIV prevention intervention delivered to JDC offenders. Participants were randomized to a five-session HIV prevention (n = 29) or health promotion (n = 28) condition and completed measures of sexual risk taking and substance use at baseline and 3 months postintervention. No between-group differences by time emerged on measures of sexual risk taking or other HIV-related behaviors and attitudes. Both groups improved their rates of HIV testing and decreased their substance use during sex over time. Delivering an HIV prevention intervention to drug court offenders is feasible; however, more intensive interventions that incorporate multiple systems and address co-occurring mental health difficulties may be needed to effect sexual behavioral change among these high-risk court-involved youth.

Prospective Analysis of the Transition to Sexual Experience and Changes in Sexual Self-Esteem among Adolescents Attending Therapeutic Schools.

Rebecca R. Swenson; Christopher D. Houck; David H. Barker; Paula D. Zeanah; Larry K. Brown

Given increased sexual risk-taking among youth with mental health problems, this study sought to understand the developmental trajectory of sexual self-esteem (SSE) among this vulnerable population and how it is impacted by sexual experiences. Participants were 185 adolescents who attended therapeutic/alternative schools in southern New England. Changes in five domains of SSE identified by Zeanah and Schwarz (1996) were examined across adolescents who either: 1) were sexually active at baseline, 2) transitioned to activity during the study, and 3) remained inexperienced at follow-up. In support of the hypothesis that changes in SSE precede onset of experience, youth who transitioned reported higher baseline scores in the Skills domain than those who remained inexperienced. SSE was subsequently impacted by sexual activity, with differences in several domains found at baseline and follow-up across level of experience. Changes in SSE following sexual experience depended, in part, on the percentage of casual partners teens reported.
