Worldwide, more than one million children are infected with human immunodeficiency virus (HIV) and in the United States it has become the sixth leading cause of death among 15-24-year-olds. Despite the trend of increasing rates of infection, advances in therapies have led to survival past 5 years of age for more than 65% of infected children. This global health threat will therefore continue to have a significant impact on child and adolescent psychiatry and psychology. This paper reviews current studies and reports on the consequences of the acquired immunodeficiency syndrome (AIDS) epidemic in the psychiatric care and development of children and adolescents infected by HIV. From a search of all the English-language-based literature on pediatric AIDS, 140 studies are reviewed which address HIV infection and its psychological and social implications. Several topics of mental health significance are examined: (1) the epidemiology of HIV, (2) neurocognitive development among those infected, (3) psychological impact of infection, and (4) the family and social context of HIV. The transition of HIV from an acute, lethal disease to a subacute, chronic disease has enormous implications for the neurocognitive and psychosocial development of children and families. As children and adolescents infected with HIV continue to live longer, normal developmental milestones and educational needs will take on new significance. Many children will continue to be adversely impacted by non-HIV factors such as poverty, inadequate medical services, and a lack of social support. This review outlines recent developments that hold promise to effectively reduce the treatment burden on the infected, their families, and health care providers and to decrease the incidence of transmission to the uninfected.

Abstract Attempted suicide among adolescents is a significant public health concern due to its frequency, coexisting physical and psychiatric problems, and economic toll. Attempters are also a high-risk group for eventual completed suicide. This review covers three major areas pertinent to attempted suicide in adolescence: characteristics of the attempt (lethality, intent, and precipitants), psychological factors associated with suicidal behavior, and follow-up course. Findings suggest there exists a significant degree of individual and family dysfunction among a large proportion of adolescent suicide attempters. However, strong evidence for the specificity of this dysfunction to suicide attempts, rather than to general emotional disturbance, was found only for hopelessness, family conflict, and contagion. In addition, the ability to devise effective interventions for adolescent suicide attempters is significantly compromised by limited knowledge of the natural course following a suicide attempt. Therefore, the need for comprehensive follow-up studies of suicide attempters should be the immediate focus of research efforts with this high-risk group.

Unprotected sexual intercourse places a substantial number of adolescents at risk for sexually transmitted disease (STD) and human immunodeficiency virus (HIV) infection. While the most effective means of preventing STD/HIV infection among sexually active adolescents is consistent condom use, little is known about the factors that influence their consistent use among adolescents. This study of adolescents (n = 1049, mean age = 16.2 years) found that of the 266 teens who recently became sexually active, only 29% reported using condoms consistently. Consistent condom use was more frequent in males, those with little history of risk behavior and those with stronger intentions to use condoms in the future. Fear and anxiety of HIV, attitudes about risks other than HIV, and other safe behavior intentions were not significantly related to consistent condom use. Although intentions and recent behavior were significantly related, a different group of factors was found to predict intention to use condoms (e.g., perception of condom use by friends, general impulsive attitudes). Identifying and understanding the factors that influence adolescent sexual behavior and intentions is important for developing maximally effective HIV education/prevention programs.

OBJECTIVE To examine the relationship between psychiatric disorders and sexual behaviors among adolescents receiving mental health treatment. Adolescents in mental health treatment have been found to have higher rates of HIV risk behavior than their peers, but data concerning the relationship between psychopathology and risk are inconsistent and limited. METHOD Eight hundred and forty adolescents (56% female, 58% African American, mean age = 14.9 years) and their parents completed computerized assessments of psychiatric symptoms via the Computerized Diagnostic Interview Schedule for Children (Shaffer, 2000a, 2000b). Adolescents also reported on sexual risk behaviors (vaginal/anal sex, condom use at last sex) and completed urine screens for a sexually transmitted infection (STI). RESULTS Adolescents meeting criteria for mania, externalizing disorders (oppositional defiant, conduct, and attention-deficit/hyperactivity disorders), or comorbid for externalizing and internalizing disorders (major depressive, generalized anxiety, and posttraumatic stress disorders) were significantly more likely to report a lifetime history of vaginal or anal sex than those who did not meet criteria for any psychiatric disorder (odds ratio [OR] = 2.0, 2.3, and 1.9, respectively). Adolescents meeting criteria for mania were significantly more likely to have 2 or more partners in the past 90 days (OR = 3.2) and to test positive for a STI (OR = 4.3) relative to adolescents who did not meet criteria for a psychiatric disorder. CONCLUSIONS The presence of internalizing and externalizing disorders, especially mania, suggests the need for careful screening and targeting of adolescent sexual behavior during psychiatric treatment.

Adolescent suicide attempts are often impulsive. It has been suggested that individuals who make nonimpulsive (premeditated) attempts have greater suicidal intent and are more hopeless than the impulsive attempters. Eighty-six adolescent suicide attempters were categorized according to the degree of premeditation of their attempt, as measured by two items of the Suicide Intent Scale. Sex, age, method of attempt, and the number of prior attempts were not useful discriminators between these groups. The nonimpulsive attempters were significantly more depressed and more hopeless than the impulsive attempters, as measured by several standardized scales. Measures of depression, hopelessness, and suicidal ideation were highly correlated in both groups. Anger turned inward and hopelessness were strongly correlated only in the premeditated group, suggesting that the nonimpulsive attempters distress may bear a strong relationship to self anger.

Theories of health behavior posit that change is accomplished by modifying factors deemed as mediators. A set of mediators from several theoretical models used in sexual risk reduction programs was assessed among a sample of 522 African American female adolescents. The goal was to determine whether self-esteem was associated with sexually transmitted disease (STD), pregnancy, and the set of theoretical mediators controlling for covariates. Bivariate analyses showed no relationship between self-esteem and STD or pregnancy; multivariate regression analysis revealed a significant relation between self-esteem and the set of mediators. Girls higher in self-esteem were more likely to hold positive condom attitudes, felt more efficacious in negotiating condom use, had more frequent communication with sex partners and parents, perceived fewer barriers to using condoms, and were less fearful of negotiating condom use. Self-esteem should be considered when designing and evaluating sexual risk reduction programs for this population.

This study investigated the relationship between parent–teen sexual communication, discussion of condoms, and condom use among adolescents in mental health treatment. Adolescents with a history of sexual intercourse and their parents completed questionnaires assessing adolescent sexual risk behavior, sexual communication, and discussion of sexual topics. Greater condom use by adolescents was associated with parent–adolescent condom discussion but was not associated with openness in sexual communication. Seventy-six percent of adolescents reported that parents had discussed condoms with them and these discussions were significantly associated with protected sexual acts. In a logistic regression, accounting for age, gender, race, and psychiatric diagnosis teens that discussed condoms with their parent were more likely to report condom use at last sex. Increasing direct communication about condoms may be an important step in increasing adolescent’s safer sex behavior. Mental health disorders and family distress may make such discussions challenging but are not an insurmountable barrier to direct discussions about condoms.

The convergence of HIV, substance abuse (SA), and mental illness (MI) represents a distinctive challenge to health care providers, policy makers, and researchers. Previous research with the mentally ill and substance-abusing populations has demonstrated high rates of psychiatric and general medical comorbidity. Additionally, persons living with HIV/AIDS have dramatically elevated rates of MI and other physical comorbidities. This pattern of co-occurring conditions has been described as a syndemic. Syndemic health problems occur when linked health problems involving 2 or more afflictions interact synergistically and contribute to the excess burden of disease in a population. Evidence for syndemics arises when health-related problems cluster by person, place, or time. This article describes a research agenda for beginning to understand the complex relations among MI, SA, and HIV and outlines a research agenda for the Social and Behavioral Science Research Network in these areas.

The evidence base and theoretical frameworks for mass media HIV-prevention campaigns in the United States are not well-developed. We describe an intervention approach using culturally sensitive mass media messages to enhance protective beliefs and behavior of African American adolescents at risk for HIV. This approach exploits the potential that mass media messages have, not only to reach a large segment of the adolescent population and thereby support normative change, but also to engage the most vulnerable segments of this audience to reduce HIV-associated risk behaviors. The results from an ongoing HIV-prevention trial implemented in 2 medium-sized cities in the United States illustrate the effectiveness of this intervention approach.

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.
