Factors associated with juvenile detention truancy   总被引:1,自引:0,他引:1  
Factors influencing truancy from a juvenile court treatment facility were investigated. Youth born in 1962 (N = 124) who were placed in the facility were compared for number of truancies, background, and personality variables. Results showed that males with prior adjudication for home or school truancy had a 65% probability of eloping from the court facility as compared to a 34% probability for youth adjudicated for other offenses. Most females were adjudicated for truancy offenses and showed a 62% probability of truancy while in the court facility. Further, for females who eloped and were returned, the probability of a subsequent truancy was above 80%. Personality characteristics of truants varied with sex: male truants were more likely to be conduct disordered youth for which impulsivity and disregard for social norms is prevalent; female truants appear more likely to be in conflict over autonomy issues.  相似文献

Adolescent alcoholism in Benin City, Nigeria   总被引:1,自引:0,他引:1  
O A Pela 《Adolescence》1986,21(82):487-492
The consumption of alcohol by Nigerian adolescents is investigated. Adolescence and alcoholism as applied in this study are defined, and the financial costs and physical and mental effects of alcohol use are described. The author used unobtrusive methods to gather data, visiting three nightclubs and an amusement park where alcohol is served in order to observe and interview adolescents. The findings show that adolescents begin drinking at an early age and consume large quantities of beer. The findings are consistent with those of other epidemiological studies. Finally, recommendations for controlling adolescent alcohol use are made.  相似文献

Belief systems and attitudes toward the death penalty and other punishments   总被引:1,自引:0,他引:1  
This study focused on the relationship of belief systems as a configural construct and conservatism-liberalism to attitudes toward the death penalty and other punishments for offenses of varying severity Extrapersonalists, the most concretely functioning of the four conceptual or belief systems posited by Harvey, Hunt, and Schroder (1961), were most in favor of the death penalty They also endorsed the most severe punishment for a variety of crimes, to a particularly greater extent than did representatives of either of the two more abstractly functioning systems The belief dimensions of Openness, Evaluativeness, and Complexity, as well as the frequency of church attendance, correlated more highly and consistently with attitudes toward punishment than did either Conservatism-Liberalism or gender Both of the latter variables failed to correlate with a number of the outcome variables and related at only low levels to the others The greater predictive power of a configural conception of personality or belief systems over a unidimensional conception seems to have been demonstrated Configural concepts may additionally be generally superior to multidimensional concepts treated linearly  相似文献

The relation of Type A behavior to IQ, academic achievement, and several clinically relevant dimensions of behavior in children was assessed in 873 fourth, fifth, and sixth graders by means of the Matthews Youth Test for Health (MYTH), the Cognitive Abilities Test (CAT), the Iowa Tests of Basic Skills (ITED), and the teachers' form of the Missouri Children's Behavior Checklist (MCBC-T). The MYTH and its competitiveness and impatience-aggression subscales were found to be differentially related to academic achievement and to account for a small but significant portion of the variance in achievement not accounted for by IQ. The subscales of the MYTH were found to be highly correlated with several clinically familiar dimensions of children's behavior. The significance of these findings for the construct validity of the MYTH is discussed.  相似文献
