Conceptual behavior in psychotic and normal adolescents.

This study has investigated conceptual behavior in 16 psychotic adolescents matched with 16 adjusted adolescents on age, IQ, and socioeconomic status. A picture sorting test was administered to both groups. Psychotic adolescents categorize and verbalize less adequately than matched controls. Psychotic adolescents use narrower categories than control Ss, perhaps reflecting an inability to reduce effectively the complexity of a stimulus array. In the qualitative analyses of verbalizations, it was found that psychotics use more idiosyncratic verbalizations, possibly indicating the greater privacy and autism of their thinking processes. The conceptual level of the verbalizations offered by the psychotics was less "abstract." Social and emotional content seems to have no effect on categorization and verbalization variables in psychotics. (16 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Outcome expectancies and gambling behavior among urban adolescents.

This project sought to identify adolescent outcome expectancies for gambling and to evaluate their relation to gambling behavior among a sample of urban adolescents. In a preliminary study, 50 outcome expectancies were identified on the basis of a literature review or generated after surveying 35 urban high school students. These expectancies were then administered to 1,076 urban high school students. Rates of at-risk and problem gambling were 14.6% and 12.7%, respectively. Exploratory and confirmatory factor analyses were performed on randomly selected halves of the sample and identified 5 expectancy domains. In a structural equation model, material gain, negative affect, and positive self-evaluation displayed significant positive relations, and negative social consequences and parent disapproval displayed significant negative relations, to gambling behavior. The model explained 48% of the variance in gambling problems and 58% of the variance in gambling frequency. These results demonstrate the salience of gambling-related cognitions in understanding the gambling behavior among these at-risk youth and suggest that expectancies may be important prevention targets for this population.

Relations between self-generated positive and negative expected smoking outcomes and smoking behavior: An exploratory study among adolescents.

The expected outcomes of drug use figure prominently in models of drug motivation. This report presents the relations between self-generated expected outcomes of smoking and smoking behavior in 674 adolescents. Expected outcomes of smoking were related to current smoking, experimentation, and susceptibility among never-smokers, even after controlling for key correlates of smoking behavior, including gender, grade, ethnicity, and peer smoking. Although more negative than positive smoking outcomes were accessible from memory, more positive than negative expected outcomes were correlated with smoking behavior. Both the content and number of self-generated expected outcomes provided unique associative information. In sum, greater elaboration of smoking-related memory networks, as well as the specific content of those networks, appear to be associated with smoking behavior.

Gesture behavior in unmedicated schizotypal adolescents.

Schizotypal personality disorder is characterized by interpersonal and verbal communication deficits. Despite the important role of gesture in social communication, no published reports examine the use of gesture by individuals with SPD. In this study, raters code gesture from videotaped interviews of unmedicated adolescents with SPD, other personality disorders, or no Axis II disorder. Results indicate that SPD adolescents show significantly fewer gestures but do not differ from the other groups in overall rate of movement. The findings are discussed in light of brain regions involved in dysfunction, parallels to schizophrenia, and treatment implications.

Physical activity and sedentary behavior: A population-based study of barriers, enjoyment, and preference.

The associations of physical activity and sedentary behavior with barriers, enjoyment, and preferences were examined in a population-based mail survey of 1,332 adults. Respondents reporting high enjoyment and preference for physical activity were more likely to report high levels of activity. Those reporting cost, the weather, and personal barriers to physical activity were less likely to be physically active. Preference for sedentary behavior was associated with the decreased likelihood of being physically active, and the weather as a barrier to physical activity was associated with the increased likelihood of sedentary behavior. These constructs can be used to examine individual and environmental influences on physical activity and sedentary behavior in specific populations and could inform the development of targeted interventions.

Rewards and adolescent health behavior: Promise or promise missed.

The paper, "Rewards and Adolescent Health Behavior," appearing on the following pages, is the second of two similar, large-scale field studies appearing in this journal on improving dental hygiene practices in junior high school students (see Lund & Kegeles, 1982). Both studies report well-designed and carefully evaluated experiments in the everyday setting of the school and raise two important issues for the reader: (1) Neither offers a great deal of encouragement in respect to the adequacy of our theoretical knowledge or technical competency in achieving substantial change in the health-promoting behaviors of school age children; and (2) Neither study encourages optimism in regard to the cost-effectiveness of health-promotion programs for adolescents.

Motivations for sex and risky sexual behavior among adolescents and young adults: a functional perspective

The implications of a functionalist perspective for understanding sexual risk taking are explored. Key motivational dimensions thought to underlie human behavior (viz., approach vs. avoidance, autonomy vs. relatedness) were used to identify 4 broad domains of sexual motivations and to develop a measure of specific motives within each of these domains. Data from both college student and community samples are used to demonstrate the psychometric adequacy of these scales and to show that having sex for different reasons predicts distinctive patterns of sexual risk taking both cross-sectionally and longitudinally: that selection into specific types of sexual relationships partially mediates these effects; and that these needs may be differentially expressed, or even suppressed, depending on relationship context. Results provide strong support for the functionalist perspective on behavior and indicate that an adequate understanding of sexual risk-taking behavior must take into account the various needs and goals that such behavior can serve.     

Abortion among adolescents.

In most countries, adolescents' access to abortion is limited by restrictions on legal abortion. Abortion is legal in the United States, but many states require parental consent or notification. Legislation mandating parental consent has been justified by several assumptions, including high risk of psychological harm from abortion, adolescents' inability to make an adequately informed decision, and benefits of parental involvement. Empirical data raise questions about the first 2 assumptions: Studies suggest a relatively low risk associated with abortion, and adolescents seeking abortion appear to make an informed choice. Less is known about effects of parental involvement. The authors review available research and discuss policy debates over parental consent in the United States and the international context.

Psychiatric disorders and sexual risk among adolescents in mental health treatment.

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.

HIV/AIDS communication among adolescents in psychiatric care and their parents.

The authors examined HIV/AIDS communication among 207 parent-adolescent dyads in psychiatric care to better understand the relationship between family communication and sexual risk behavior in an at-risk population. Dyads reported content and rated quality of family HIV/AIDS discussions, and adolescent sexual risk was assessed. Families discussed transmission, prevention, consequences, myths, and compassion. Parent-reported discussion of consequences was associated with greater sexual risk behavior, but only for girls. Higher quality communication reported by adolescents was associated with less sexual risk. Parents may send different messages about HIV/AIDS to sons versus daughters, and messages related to consequences may not effectively reduce risk among daughters. However, for boys and girls in psychiatric care, teaching parents how to discuss HIV/AIDS may promote safer sexual behavior. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The theory of planned behavior and healthy eating.

Application of the theory of planned behavior (TPB) to healthy eating in 144 health promotion clinic attendees is reported. Respondents completed self-report TPB measures after the clinic (Time 1) and 6 months later (Time 2) with a measure of perceived past behavior. Intention stability was assessed on Time 1-2 differences. Six years later (Time 3), respondents completed measures of healthy eating intentions and behavior. Intentions were predicted by attitudes, perceived behavioral control, and perceived past behavior (cross-sectionally). Healthy eating behavior (Time 3) was predicted from intentions (Time 2). As intention stability increased, intentions and perceived past behavior became stronger and weaker predictors of behavior, respectively. Implications for understanding health cognitions in long-term performance of health behavior are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Predictors of mental health among adolescents from immigrant families in Portugal.

The aims of this study were to investigate the degree of mental health problems among adolescents with immigrant background in Portugal and the factors that may predict mental health problems. The study sample consisted of 755 immigrant adolescents from seven ethnocultural groups (Cape Verdeans, Angolans, Indians, Mozambicans, East Timorese, Sao Tomese, and Guineans) and 320 native Portuguese adolescents. Generally, most respondents did not report major psychological adjustment problems. Adolescents from immigrant families reported fewer mental health problems than their native Portuguese counterparts, and girls reported more mental health problems than did boys. Predictive factors—sociodemographic, intercultural contact, and psychosocial adjustment variables—were significantly linked to youths’ mental health. Major predictors of poor psychological adjustment were perceived discrimination, social difficulties, and behavioral problems. As expected, different factors explained the psychological adaptation of adolescents by gender. Implications of the study for counselors are discussed.

Involvement in traditional and electronic bullying among adolescents.

The increasing availability of Internet and cell phones has provided new avenues through which adolescents can bully. Electronic bullying is a new form of bullying that may threaten adolescent social and emotional development. In this study the relation between involvement in electronic and traditional bullying was examined. Eighty-four adolescents completed questionnaires regarding their involvement in traditional and electronic bullying. Results show that students' roles in traditional bullying predicted the same role in electronic bullying. Also, being a victim of bullying on the Internet or via text messages was related to being a bully at school. Traditional victims were not found to be electronic bullies. Perceptions of the effects of and motivations for electronic bullying are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The relation between exposure to violence and social information processing among incarcerated adolescents.

Combining evidence from social learning theory with reports of the association between community violence exposure and aggressive behavior development, the authors examined the link between specific characteristics of violence exposure and social information-processing mechanisms (N. R. Crick & K. A. Dodge, 1994; K. A. Dodge, 1980, 1986) in a sample of highly aggressive, incarcerated adolescent boys (N?=?110). Results demonstrated that victimization by severe violence was significantly related to approval of aggression as a social response, problems with the interpretation of social cues, and maladaptive social goals. Witnessing severe violence, in contrast, was related to perceived positive outcomes for the use of aggression. These data suggest the importance of examining the severity and modality of exposure to community violence for understanding patterns of social–cognitive functioning among adolescents exposed to violence.

Tolerance for stress among institutionalized mildly retarded adolescents.

A sample of institutionalized adolescent borderline and mildly retarded patients was administered the mild stress of a mirror tracing task and a severe stress of hand cooling in ice-cold water for 25 minutes. The sample consisted of 4 subgroups selected by the ratings of nursing personnel along the 2 dimensions of good and poor adjustment to the authority structure of an institutional dormitory and good or poor internalized control of behavior in the dormitory. Performance in the 2 stress experiments reported was poorer for those patients who manifested poorer adjustment to the dormitory, and/or poor behavioral control.

Gender differences in psychiatric comorbidity among adolescents with substance use disorders.

The authors examined gender differences in rates of comorbid psychiatric disorders among adolescents with 1 or more psychoactive substance use disorders. Baseline diagnostic data were obtained from 135 adolescents, ages 12 to 19, and their parents-guardians, who participated in a study to develop and efficacy test Integrated Family and Cognitive-Behavioral Therapy. Rates of attention-deficit/hyperactivity disorder and conduct disorder were higher among drug-abusing male adolescents compared with drug-abusing female adolescents. However, high rates of disruptive behavior disorders also characterized drug-abusing female adolescents. Similarly, drug-abusing female adolescents exhibited a higher rate of major depression compared with drug-abusing male adolescents. However, rates of dysthymia, double depression (i.e., major depression and dysthymia), and bipolar disorder were equivalent between genders.

Understanding the relations among gender, disinhibition, and disruptive behavior in adolescents.

This study examined whether disinhibition shows similar relations with attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) symptomatology among male and female adolescents. The mixed-incentive or punishment condition of Newman's go/no-go task was administered to 172 adolescents. As expected, ADHD symptoms in boys and girls were predictive of disinhibition (i.e., commission errors) in the mixed-incentive but not punishment condition. Also consistent with expectations, CD symptoms in boys were predictive of disinhibition in the mixed-incentive but not punishment condition. In contrast, CD symptoms in girls were not predictive of disinhibition in either condition. These findings are discussed in terms of implications for understanding sex differences in the etiology of ADHD and CD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Long-term effects of implementation intentions on prevention of smoking uptake among adolescents: A cluster randomized controlled trial.

Objective: To test the efficacy of implementation intentions in reducing smoking uptake in a sample of adolescents. Design: Classes of adolescents (aged 11–12 years) were randomly allocated to one of four conditions: implementation intention, self-efficacy, two control conditions. An implementation intention or a self-efficacy manipulation (both formed in relation to how to refuse offers of cigarettes) was completed by intervention condition participants at 0, 4, 8, 12, 16, 20, and 24 months. Main Outcome Measures: Long-term smoking behavior (self-report and objective) was assessed at 48 months post-baseline. Results: There were no differences between the two control conditions and the self-efficacy condition. Controlling for baseline smoking, sex, attitudes to smoking, friends and family smoking, and the multilevel nature of the data, intention-to-treat analyses indicated the implementation intention manipulation significantly reduced self-reported smoking compared to the other three conditions combined. Analyses on objectively assessed smoking (carbon monoxide breath measure) in a random subsample of participants also indicated that the implementation intention manipulation compared to the other three conditions significantly reduced smoking. Conclusion: Implementation intentions can reduce smoking in adolescent samples. Implications for using implementation intentions to reduce smoking in adolescents are discussed.

Perceived racial/ethnic discrimination, posttraumatic stress symptoms, and health risk behaviors among Mexican American adolescents.

Utilizing the concept of race-based traumatic stress, this study tested whether posttraumatic stress symptoms explain the process by which perceived discrimination is related to health risk behaviors among Mexican American adolescents. One hundred ten participants were recruited from a large health maintenance organization in Northern California. Mediational analyses indicated that adolescents who perceived more discrimination reported worse posttraumatic stress symptoms, controlling for covariates. In turn, adolescents who experienced heightened posttraumatic stress symptoms reported more alcohol use, more other drug use, involvement in more fights, and more sexual partners. Perceived discrimination was also directly related to involvement in more fights. Results provide support for the notion of race-based traumatic stress, specifically, that perceived discrimination may be traumatizing for Mexican American adolescents. Counseling psychologists and counselors in schools and community settings should assess Mexican American adolescents for the effects of discrimination and provide appropriate interventions to reduce its negative emotional impact.

Peer relations among adolescents with female same-sex parents.

This study examined associations among family type (same-sex vs. opposite-sex parents), adolescent gender, family and relationship variables, and the peer relations of adolescents. Participants included 44 adolescents parented by same-sex female couples and 44 adolescents parented by opposite-sex couples, matched on demographic characteristics and drawn from a national sample. On both self-reported and peer-reported measures of relations with peers, adolescents were functioning well, and the quality of their peer relations was not associated with family type. Regardless of family type, adolescents whose parents described closer relationships with them reported higher quality peer relations and more friends in school and were rated as more central in their friendship networks.
