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

Validity of the Millon Clinical Multiaxial Inventory in the assessment of affective disorders 总被引:1,自引:0,他引:1
The Millon Clinical Multiaxial Inventory (MCMI) was administered to 270 adult outpatients with major affective disorders at the same time that a semistructured, diagnostic interview was conducted by a clinician. The mood of the patient was then rated, and the clinician completed the Hamilton Depression Rating Scale and the Mania Rating Scale. A consensual diagnosis was arrived at by the team of investigators using DSM-III criteria. Significant correlations were found between four MCMI affective scales and the global mood state of the patient. Analysis of covariance indicated that the MCMI affective scales are significantly related to DSM-III affective disorders even after the effect of the current mood of the patient is partialled out. The clinical usefulness of each of the scales is discussed. 相似文献

In this study, 24 professional writers completed a short pencil-and-paper questionnaire on which they indicated how they felt before, at a pause, and after specific writing episodes. The intensity with which they experienced 20 emotions was assessed, as was the frequency with which these emotions were experienced when writing in general. Results indicated that the professionals experienced positive emotions significantly more often when writing in general than they experienced either negative-active or negative-passive emotions. Negative-passive emotions such as boredom, shame, and shyness were particularly rare and weak. During the actual writing process, positive emotions tended to intensify, whereas negative-passive and negative-active emotions resisted change. Sponsorship of writing had little impact on the quality of emotions experienced during the process. The professional poets, however, experienced negative-active emotions significantly more often when writing in general than did the prose writers. 相似文献
