This study reports on the reliability and concurrent validity of both the trait and state forms of the Multiple Affect Adjective Check List (MAACL) with a high school population, age range of 14-16 years and educational range of 9th and 10th grades (N = 403). Alphas of the four scales (anxiety, depression, hostility, and positive affect) ranged from .67 to .91. Correlations with a check-list of stress-related symptoms and an inventory of the number of extracurricular activities in which the students participated were significant and in the expected direction. Means and standard deviations on the MAACL scales were similar to those of college students. Sex differences were found on some of the scales. The findings indicate that the MAACL is sufficiently reliable and valid to warrant additional use with an adolescent population. 相似文献

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

Biofeedback, cognitive training and relaxation techniques as multimodal adjunct therapy for hospitalized adolescents: a pilot study 总被引:1,自引:0,他引:1
Modifications and adjuncts to traditional therapy techniques appear to be necessary for successfully treating hospitalized adolescents with impaired social and verbal skills, and a history of acting-out behavior. Modified therapy groups were combined with a structured biofeedback and cognitive training program to help these adolescents control anger and modify their behavior. Used in conjunction with training and practice in relaxation techniques, this multimodal treatment approach appeared to be helpful in both reducing incidents of acting out on residential units, and in reaching individualized therapeutic goals. The present paper describes use of this multimodal approach within selected residential settings, and outlines the structured materials developed by the authors. 相似文献

R E Muuss 《Adolescence》1986,21(82):257-267
Bulimia, an eating disorder, recently has emerged as a major mental health problem, especially among adolescent females. The bulimic experiences periods of compulsive binge eating followed by purges to rid the body of unwanted calories. Binges are triggered by intense emotional experiences, such as loneliness, anger, rejection, or stress. Associated features of bulimia are secretiveness, depression, drug abuse, preoccupation with body image and sexual attractiveness, and an awareness that the behavior is abnormal. The physical side effects include dental problems, inflamed esophagus, EEG abnormalities, abdominal or urinary disturbances, and changes in blood sugar level. Cognitive disturbances related to binging and purging are perfectionistic, egocentric, and distorted thinking, misconceptions about nutritional requirements, unreasonable goals and expectations, and disturbed affect. Bulimics resist treatment; however, such methods as cognitive, group, family, behavior, and drug therapy, and hospitalization appear promising. 相似文献
