Epidemiological studies in the United States estimate HIV seroprevalence rates ranging between 4% and 23% for serious mentally ill adults (SMIA; i.e., schizophrenia, bipolar disorder, and other chronic disorders with psychotic features), with substantially greater estimates for risky sexual behaviors. Among the most consistent factors linked to HIV risk in non-SMIA populations is a history of emotional, physical, or sexual abuse. The current study examined the intersection of abuse history and HIV sexual risk behavior in SMIAs with a group of men (n = 64) and women (n = 115) recruited from eight geographically diverse and representative clinical sites around Florida. A cross-sectional interview revealed a high prevalence of alcohol and other drugs problems, as well as a history of emotional, physical, or sexual abuse in 75% of the participants, with 68% of these reporting multiple types of abuse. Compared to nonabused counterparts, those with a history of abuse reported significantly greater: (a) lifetime and current psychiatric symptoms, (b) recent unprotected sexual intercourse, and (c) crack cocaine, heroin, and marijuana use. No gender differences were detected in the associations of abuse history and sexual risk behaviors. These results underscore the need for HIV prevention efforts targeted to SMIAs and the critical importance of addressing abuse history in interventions with this underserved population.  相似文献

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.

Based on a model by Cyranowski, J., et al. (2000), Arch. Gen. Psychiatry 57: 21–27, adolescents at-risk for the development of depressive symptoms were identified. Adolescents were considered at-risk if they had 2 or more of the following early adolescent risk factors: (1) insecure parental attachment, (2) anxious/inhibited temperament, (3) low instrumental coping skills, and (4) early pubertal maturation. Nonrisk adolescents had zero or just one risk factor. Using data from a 10-year longitudinal study on the development of adolescents’ health, with 5 points of data assessment (i.e., 6th, 7th, 8th, 12th, and 12 + 4 follow-up), the impact of the four early adolescent risk factors on the development of emotional tone was investigated. Emotional tone was measured by the Emotional Tone Scale of the SIQYA (Petersen, A. C., et al. (1984), J. Youth Adolesc. 13: 93–111), an indicator for positive emotional tone and low depressed affect. Growth curve modeling was applied to reveal significant gender differences in level and slope for the development of emotional tone over the adolescent years. Latent Growth Curve Models can be seen as a combination consisting of repeated measures analysis of variance and autoregressive analyses to evaluate the latent change of the variables under investigation (Rovine, M. J., and Molenaar, P. C. M. (2000), Multivar. Behav. Res. 35(1): 51–88). At-risk girls revealed poorer levels of emotional tone which stayed almost at the same low level up to young adulthood (i.e., 12 + 4), indicating a long lasting impact of the specified risk factors. In contrast, at-risk boys showed poorer emotional tone in early adolescence, but at the end of adolescence boys at-risk had the same level of emotional tone as nonrisk boys. At-risk girls showed significantly higher levels of depressive symptoms at grade 12 and at 12 + 4.Assistant Professor at the Department of Psychology, University of Erlangen-Nuremberg.
