OBJECTIVES: Although a wealth of literature suggests that childhood physical, emotional, and sexual abuse are related to later-life HIV-related risk behaviors, few studies have explored disinhibition (e.g., impulsivity, risk-taking propensity, and sensation-seeking) as a risk factor in this relationship. METHOD: This cross-sectional study examined impulsivity, risk-taking propensity, and sensation seeking as mediators in the relationship between abuse history and engagement in HIV-related risk behaviors among a sample of 96 inner-city African American adolescents. RESULTS: Findings indicated that abuse history was positively related to self-reported engagement in HIV-related risk behaviors (B=.027, SE .008, beta=.32, sr(2)=.105, p=.001), as well as risk-taking propensity (B=.35, SE .11, beta=.30, sr(2)=.090, p=.003) and sensation seeking (B=.17, SE .05, beta=.35, sr(2)=.124, p=.0004). Abuse history was not related to impulsivity. Further, while sensation-seeking and risk-taking propensity (to a lesser extent) mediated this relationship, impulsivity did not. CONCLUSIONS: These findings provide an initial step in the examination of the mechanisms underlying the relationship between childhood abuse and engagement in HIV-related risk behaviors.  相似文献   

Relationship of Study Strategies and Academic Performance in Different Learning Phases of Higher Education in Hong Kong     

Michael CW Yip  Olive LL Chung 《Educational Research and Evaluation》2013,19(1):61-70

The present study aims (1) to investigate the specific study strategies that may lead to a success in Matriculation as well as at University; and (2) to investigate whether these study strategies that are effective in Matriculation also work efficiently at University. A revised version of the Learning and Study Strategies Inventory (LASSI, ) was used and we found that there were significant differences between study habits of students with high academic achievement and those with low academic achievement in Matriculation. However, this was not the case at University. More importantly, we also found that those effective study strategies used in Matriculation may not work at University. These results are discussed in terms of the focus and the academic demand of different learning phases of higher education in Hong Kong.  相似文献

Few studies have examined stability and change in attachment during adolescence. This 5‐year longitudinal study (a) examined whether prototype or revisionist developmental dynamics better characterized patterns of stability and change in adolescent attachment (at T1, N = 176; M_age = 14.0 years, SD = 0.9), (b) tested potential moderators of prototype‐like attachment stability, and (c) compared attachment stability in adolescence to stability in adulthood. The results supported the prototype model, which assumes that there is a stable, enduring factor underlying stability and change in attachment. Exploratory moderation analyses revealed that family conflict, parental separation or divorce, minority status, and male sex might undermine the prototype‐like stability of adolescent attachment. Stability of attachment was lower in adolescence relative to adulthood.  相似文献   

The impact of childhood abuse on inpatient substance users: Specific links with risky sex,aggression, and emotion dysregulation

Adults with substance use disorders (SUDs) report a high prevalence of childhood abuse. Research in the general population suggests specific types of abuse lead to particular negative outcomes; it is not known whether this pattern holds for adults with SUDs. We hypothesized that specific types of abuse would be associated with particular behavioral and emotional outcomes among substance users. That is, childhood sexual abuse would be associated with risky sex behaviors, childhood physical abuse with aggression, and childhood emotional abuse with emotion dysregulation. 280 inpatients (M age = 43.3; 69.7% male; 88.4% African American) in substance use treatment completed the Childhood Trauma Questionnaire (CTQ), HIV Risk-Taking Behavior Scale, Addiction Severity Index, Difficulties with Emotion Regulation Scale (DERS), Distress Tolerance Scale (DTS), and Affect Intensity and Dimensions of Affiliation Motivation (AIM). Consistent with our hypotheses, the CTQ sexual abuse subscale uniquely predicted exchanging sex for cocaine and heroin, number of arrests for prostitution, engaging in unprotected sex with a casual partner during the prior year, and experiencing low sexual arousal when sober. The physical abuse subscale uniquely predicted number of arrests for assault and weapons offenses. The emotional abuse subscale uniquely predicted the DERS total score, AIM score, and DTS score. Among substance users, different types of abuse are uniquely associated with specific negative effects. Assessment of specific abuse types among substance users may be informative in treatment planning and relapse prevention.  相似文献
