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

Destructiveness in primitive personalities is not restricted to a segment of the person as it is in the case of neurotics, but is global and pervasive. This destructiveness is meaningfully configured in a manner which cannot fully be accounted for by constitutional factors or be comprehended from the individual, intrapsychic, conflictual viewpoint of classical psychoanalysis. It follows an interpersonally meaningful pattern and therefore has adaptive significance in the contemporary life of the individual. The adaptive model I propose does not violate essential canons of psychoanalytic theory, for it can simultaneously be conceptualized in terms of intrapsychic structure and dynamics. This model holds out the possibility for a therapeutic approach to primitive personality organization which differs in some but by no means all respects from classical analysis. 相似文献
