The sexual objectification of girls and aggression towards them in gang and non-gang affiliated youth

Sexual objectification is related to various negative attitudes and outcomes, including rape proclivity and reduced moral concern for the objectified, which suggests that objectification has implications for aggression. Our study examined the relationship between objectification and general aggressive behaviour in adolescents, including gang-affiliated youth. We hypothesized that (1) objectification would correlate with aggression towards girls, (2) gang affiliation would correlate with objectification and aggression towards girls, and (3) objectification and gang affiliation would interact such that strongly affiliated participants who objectified girls would be most aggressive towards them. We also hypothesized that sexual objectification would be a significant predictor of aggression above and beyond other factors, such as trait aggression. As predicted, objectification correlated with aggression towards girls and with gang affiliation, which also correlated with aggression. In addition, objectification predicted aggression towards girls, after controlling for other relevant factors. Further, we found an objectification?×?gang affiliation interaction, which differed from our original predictions. Among participants low in gang affiliation, objectification of girls predicted levels of aggression towards them. Among those high in gang affiliation, however, objectification did not predict aggression. We discussed the implications of our findings for general aggression.

Evidence-based practice in group work with incarcerated youth

As a result of the Youth Criminal Justice Act's increased focus on restorative justice, treatment, rehabilitation, and reintegration of youth, many more juvenile offenders require mental health services while resident in youth detention facilities [Youth Criminal Justice Act (2002, c.1). Ottawa: Department of Justice Canada. Retrieved September 19, 2008 from http://laws.justice.gc.ca/en/Y-1.5]. Several common characteristics such as violence, aggression, and other antisocial behaviors, associated with criminal behavior, have been identified among male and female offenders. Dialectical behavior therapy, originally developed by Linehan [Linehan, M. M., 1993a. Cognitive–behavioural treatment of borderline personality disorder. New York: Guildford Press] for chronically parasuicidal women diagnosed with borderline personality disorder, has been successfully modified for use with other populations, including violent and impulse-oriented male and female adolescents residing in correctional facilities. The intent of this article is to encourage the wider use of dialectical behavior therapy (DBT) with young offenders. It includes an extensive review of the evidence-base to date and describes some of the creative modifications that have been made to standard DBT program format to meet the particular needs of various groups in both Canada and the United States. In keeping with the movement toward more evidence-based practice, the authors argue that DBT is a promising approach in group work with incarcerated adolescents and should be more widely used.     

WHEN IT HAPPENS IN A FAMILY: AIDING PARENTS OF SUBSTANCE‐ABUSING ADOLESCENTS*

This article first summarizes key data on the scope of teen substance abuse and the lack of teen access to needed treatment services. It then describes how and why attorneys may be helpful to parents who discover their teen's drug or alcohol problem and seek advice and counsel about the legal implications of various actions that can or may be taken. The article explores such issues as parents finding illegal drugs in the house or on their teen's person, various modalities of treatment and how family members are involved, how parents might secure residential evaluations for their youth without the necessity of juvenile court involvement (and why this is important), concerns about placing youth in unlicensed residential treatment facilities, health insurance coverage issues, home drug testing, and how past American Bar Association (ABA) policy on youth drug and alcohol abuse is being followed up with a new ABA project to aid parents of substance‐abusing teenagers and their families.     

Using an evolutionary perspective to understand the relationship between physical aggression and academic performance in late adolescents

In this study, we applied an evolutionary perspective to analyze the relationship between aggressiveness, academic performance, and sociality in a population of 528 adolescents of both sexes. In men, we expect physical aggression (PA) and sociality to be negative predictors of academic performance. However, in women, PA would be a negative predictor of academic performance, and sociality a positive one. Our results report a negative association between academic performance and PA in both sexes. As we expected, social effect derived from the use of PA seems to be different for each sex, where men could display a rebellious attitude to increase chances of finding a mate. In contrast, results for women are not conclusive, because no relationship between academic performance and any aggressive mechanism, were predicted by sociality. We conclude that an evolutionary framework, which includes sex-specific hypotheses, is appropriate to obtain a holistic perspective of this phenomenon.     

Reliability and validity of the Psychopathy Checklist: Youth Version in Dutch female adolescents

In the present study, the reliability and construct validity of the Dutch version of the Psychopathy Check List: Youth Version (Psychopathie Checklist: Jeugd Versie; De Ruiter, Kuin, De Vries & Das, 2002) were examined in a sample of female adolescents admitted to a secure treatment institution (N=67). The study provides mixed support for the internal reliability of the PCL:YV in female adolescents. Interrater reliability was found to be adequate at the level of factor and total PCL:YV scores. Poor reliability was demonstrated for the behavioral items of the PCL:YV in particular. Finally, the construct validity of the PCL:YV total and factor scores was supported by theoretically meaningful and significant associations with scores on the Minnesota Multiphasic Personality Inventory (MMPI) and the Interpersonal Checklist-Revised (ICL-R). The applicability of PCL:YV items to female adolescents is discussed.     

Prevalence and Predictors of Sexual Risks Among Homeless Youth

This study examined prevalence of sexual risks among homeless adolescents and described factors associated with those risks. Community-based outreach methods were used successfully to access this difficult-to-reach population. The sample included 203 homeless youth aged 15–22 recruited from community sites. Questionnaire items addressed demographics, sexual behaviors, alcohol/drug use, STI history and testing, and pregnancy history. In cross-sectional analysis, 58.7% of males and 75.6% of females reported recent sexual intercourse. Of those, one third of males and half of the females used no barrier method with at least one partner. Both gender (female) and race/ethnicity (non-Black) were associated with having intercourse without a barrier contraceptive method. Over one fifth reported a history of survival sex or receiving money, drugs, clothing, shelter, or food for sex. These results show disturbingly high rates of a number of sexual risks, reinforcing the need for targeted interventions with this highly vulnerable population.     

Jurors' Perceptions of Adolescent Sexual Assault Victims Who Have Intellectual Disabilities

Children and adolescents with intellectual disabilities are especially likely to be sexually abused. Even so, their claims are not likely to be heard in court, possibly because people assume that jurors will not believe them. We tested this assumption in a mock-trial study in which 160 men and women watched videotaped excerpts from an actual trial. As predicted, when the 16-year-old sexual assault victim was portrayed as mildly mentally retarded instead of as having average intelligence, jurors were more likely to vote guilty and had more confidence in the defendant's guilt; considered the victim to be more credible and the defendant to be less credible as witnesses; and rated the victim as more honest, less capable of fabricating the sexual abuse accusation, and less likely to have fabricated the sexual abuse accusation. Men and women were affected similarly by the disability manipulation, but women were generally more pro-prosecution in their case judgments and perceptions than were men. Finally, jurors who had more liberal views toward persons with disabilities were more likely than other jurors to make pro-prosecution judgments on measures of guilt. Implications for psychological theory and the law are discussed.     

Eating Problems and Their Risk Factors: A 7-Year Longitudinal Study of a Population Sample of Norwegian Adolescent Girls

The longitudinal stability of eating problems and their relationships to risk factors were investigated in a representative population sample of 623 Norwegian girls aged 13–14 followed over 7 years (3 time points). Three eating problem symptoms were measured: Restriction, Bulimia-food preoccupation, and Diet, all taken from the12-item Eating Attitudes Test. The aim of the study was to investigate the stability of these eating problem symptoms both as separate components (as opposed to total symptom load) as well as from a syndrome perspective. Over 7 years, dieting behavior showed the highest correlational stability (0.32). Regarding stable eating problem syndromes, at all 3 time points, 1 group of girls with generalized eating problems was found, characterized by simultaneously pronounced bulimic tendencies and dieting. However, we did not establish individual stability across 7 years for this syndrome group. Through development, eating problem symptoms were associated with characteristic risk factors. Similarities and differences between findings regarding eating problems and eating disorders are discussed.     

Construct Validity of the Offer Self-Image Questionnaire and Its Relationship with Self-Esteem,Depression, and Ego Development

Construct validity of the Offer Self-Image Questionnaire (OSIQ) was studied in a sample of 194 normal Finnish adolescents from 14 to 16 years of age. Confirmatory factor analysis provided support for the hierarchical structure of adolescents’ self-image with 5 lower-order factors loading on a single higher-order factor. Lower-order factors were Personally Anxious Self, Social Relationships, Sexual Attitudes, Family Relationships, and Social Conscience. The relationships between the self-image areas of the OSIQ, global self-esteem, depression, and ego development were also examined. The results support the construct, convergent, and discriminant validity of the presented structure of the OSIQ.He received M.A. from University of Helsinki.
