Certification is the process whereby older juveniles who have committed felony offenses are transferred from juvenile courts to adult courts. The present study examined the variables that influence decisions in these cases and used attribution theory to conceptualize the process. Data were obtained from files of 150 youths on whom certification petitions had been filed from January 1981 to October 1984. Of these, 125 had been certified and 25 had not. The sample comprised 148 males and 2 females. Data included seriousness of the offense, previous offenses, potential for aggressiveness, level of involvement in the offense, age, court in which the case was heard, year in which the case was heard, IQ, family income and sex. Level of involvement, seriousness of the offense and potential for aggressiveness had the strongest association with certification outcomes, with those high on these measures significantly more likely to be certified. The cluster that predicted outcomes best included level of involvement, seriousness of the offense, potential for aggressiveness, IQ, year in which the case was heard, court in which the case was heard, sex and previous offenses. The most explicitly behavioral variable—how actively the child participated in the offense—was the best single predictor of outcomes.  相似文献

Previous research has found that greater autonomy for incarcerated adolescents is associated with pro-social outcomes. The present paper interprets the pro-social impact of autonomy in terms of three established lines of research in social psychology: leadership style, coercive social control, and reactance. In addition, it attempts to clarify whether autonomy in this setting has a direct influence on residents' values or an indirect influence resulting from an increase in residents' acceptance of the treatment goals. Data were collected by questionnaires administered to 434 residents and 156 staff members at four residential institutions for adjudicated adolescents. The data were analyzed using a structural equation model with unobserved variables (LISREL). A model positing both direct and indirect influences of autonomy fit the data very well. Autonomy contributed to pro-social values both through greater acceptance of the treatment goals as well as through a direct influence on values.  相似文献
