Delinquent youths and family   总被引:2,自引:0,他引:2  
L LeFlore 《Adolescence》1988,23(91):629-642
This study investigates the relationship of several demographic variables, family structure (number of siblings in house, family intactness, sibling rank, number of persons in household) and family environment (family relationship, personal growth, and family system maintenance). The family environment variables are dimensions of the Family Environment Scale (Moos, 1974). The subjects reported a fairly good reliability on the scale (Cronbach's alpha = .753). The data collection for the present study represents 198 youths: 68 official chronic delinquents and 130 official nondelinquents. A discriminant analysis was used to determine which of the demographic and family environment variables had the most predictive power in discriminating between the groups. The general analysis indicated that ten of the variables explained 49% of the variance between the chronic delinquent and nondelinquent groups. Personal growth was found to have the most discriminating power, followed by number of siblings, race, sex, and system maintenance.  相似文献

This paper attempts to indicate why psychoanalysts should be interested in marital therapy. It discusses the clinical advantages and disadvantages of marital therapy as compared to psychoanalysis, describes the contributions of the classical psychoanalytic viewpoint to marital therapy, and finally, attempts to complement the classical psychoanalytic viewpoint with an object-relations viewpoint which can illuminate marital dynamics and provide interpretive content during the course of marital therapy.  相似文献

Four clinical examples of oedipal-based transference across gender lines are presented with the aim of illustrating (1) its existence, (2) the defenses against its emergence, and (3) the use of the analyst's gender as both an organizer of and resistance to certain transference manifestations. Factors that contribute to the availability for analysis of cross-gender transference are discussed, as are the resistances and other obstacles to its actualization.  相似文献

Recidivism data derived from various sources over a follow-up period of 1–11 yr, provided the basis for appraising the effectiveness of a comprehensive cognitive-behavioral treatment program for familial and nonfamilial child molesters. Unofficial records held by police and Children's Aid Societies proved to be the best data for estimating recidivism. These data revealed increases in recidivism with longer follow-up periods, but there were consistent advantages for the treated over the untreated patients. Men who had sexually abused the daughters of other people demonstrated the clearest treatment benefits. The younger offenders and those who had engaged in genital-genital contact with their victims were more likely to reoffend even if they were treated. Contrary to the expectations of behavior therapists, indices of deviant sexual preferences did not predict outcome.  相似文献

Performances of noncollege student young adults, middle-aged adults, and elderly adults were contrasted on word temporal memory and paired-associate learning tasks. A comparison group of college-student subjects was also evaluated on each task. Significant effects for age variation were found for each task. The age sensitivity for temporal memory conflicts with one of the criteria commonly established for determining the automaticity of a memory task. In addition, moderately high positive correlations were found for each age group between word temporal memory scores and paired-associate learning scores, implying the involvement of effortful processes over the adult lifespan in word temporal memory.  相似文献

MMPI profiles of female adolescents hospitalized on a general pediatrics floor following a suicide attempt were compared to a control group of medically hospitalized, female adolescents referred for psychiatric evaluation. The suicide attempters had only a lower score on the K scale when compared to the control group. Results do not suggest that a single MMPI profile differentiates suicide attempters from a comparison group of adolescents with emotional difficulties. Implications of these findings are discussed.  相似文献
