Severe hair-pulling is characteristic of trichotillomania, an impulse control disorder not otherwise classified. Other pathological habits, including severe nail-biting and skin-picking, are also prevalent and are potentially diagnosable as stereotypic movement disorder. There is increasing awareness of the morbidity associated with these kind of habit disorders but, to date, relatively few randomized controlled trials of pharmacotherapy or psychotherapy have been undertaken. Advances in the understanding of the underlying cognitive-affective mechanisms driving stereotypies in animals and humans may ultimately lead to new approaches. An affect regulation, behavioral addiction, and cognitive control (A-B-C) approach is outlined to conceptualizing and managing these conditions. 相似文献

In the present study we investigated the relationship between suicidal behavior and aspects of bodily perception and parental care. Measures of bodily perception included measures of tactile sensitivity, body attitudes, and body experiences. Measures of parental care included parental bonding, negative and positive touch, and early maltreatment. One hundred and two adolescents (suicidal and nonsuicidal inpatients, and a control group) participated in the study. It was hypothesized that suicidal adolescents would (1) have higher tactile sensation thresholds, and more negative body attitudes and experiences; and (2) report less parental care, lower positive and higher negative parental touch, and higher parental maltreatment. It was also hypothesized that bodily sensitivity would mediate the relationship between suicidal tendencies and perceived negative early care. These hypotheses were confirmed. The role of a negative bodily self in suicidal behavior is proposed and discussed. 相似文献

This study examines the relationship of three sociocultural factors—media influence, peer teasing, and parent teasing/comments and three potential moderator variables—self-esteem, social comparison, and endorsement of male strength and athleticism—to drive for muscularity in middle school boys. There were 287 seventh and eighth grade boys who completed a questionnaire measuring these variables as well as body mass index (BMI) and pubertal status. Results indicated that media influence and male physical attributes endorsement were particularly important correlates of drive for muscularity. These findings have implications for programs designed to prevent body dissatisfaction among adolescent boys. 相似文献

The Substance Abuse Subtle Screening Inventory-Adolescent (SASSI-A) is used in evaluation and treatment planning for incarcerated juveniles. Validity of the SASSI-A in a juvenile correctional facility was examined using archival data. Findings generally support the validity of SASSI-A substance use scales. However, there is concern regarding the potential for ethnic bias in this setting. Cut-scores suggest that the SASSI-A may best be used for detecting problematic alcohol consumption using the Face Valid Alcohol Scale > or = 3. Future studies should more closely investigate whether the three underlying dimensions of the SASSI-A are useful in treatment planning. Results are presented in light of the relatively new SASSI-A2. 相似文献

Neurobiology of Cocaine-Induced Organic Brain Impairment: Contributions from Functional Neuroimaging
Strickland Tony L. Miller Bruce L. Kowell Arthur Stein Richard 《Neuropsychology review》1998,8(1):1-9
The present review is directed at imparting the current knowledge regarding functional neuroimaging as a tool for enhancing the understanding of cerebrophysiologic and neurobehavioral consequences of stimulant abuse. Stimulants like cocaine are capable of inducing clinically significant neurocognitive impairment through direct action on the brain, and indirectly through other organs that influence cerebral physiology. Neurochemical dysregulation including profound effects on the serotonergic and dopaminergic systems have substantial physiological and neurobehavioral consequences. Brain hemorrhages, transient ischemic attacks, strokes, and seizures frequently follow cocaine use. The residual cerebropathologic consequences of cocaine are seen only in significant or pronounced brain events when structural neuroimaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) are employed. However, recent research with newer functional neuroimaging techniques such as single photon emission, positron emission tomography, and quantitative electroencephalography have revealed high rates of significant alteration in brain function among cocaine users, with negative structural imaging studies. These findings are often associated with impairment on neuropsychological evaluation, also in the absence of positive findings on CT and MRI. Both cerebral metabolic and hypoperfusion anomalies are seen, especially in anterior and temporal brain regions. Observed changes can persist for months, and for some patients, may represent a permanent change in brain functioning. 相似文献

This study investigated the predictive validity to 5 years of age of nonverbal communicative skills administered at 13 months. Subjects (N = 103) were Norwegian infants with birthweight below 1501 gms. The predictors included infant competence assessed by the Early Social-Communication Scales (ESCS). Cognitive competence at 2 years was measured by the Bayley Mental Development Scale, and at 3 and 5 years by the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE). Language competence at 2 and 3 years was assessed by the Reynell Developmental Language Scales, and at 5 years by a verbal comprehension factor derived from the SB:FE. Partial correlations and multiple regression analyses suggest that the infants' initiation of communication was related to cognitive ability and language skills up to 5 years of age. In particular, joint attention was the most consistent predictor of the subsequent competencies. The Bayley cognitive index was overruled as a predictor when used in combination with initiation of joint attention. 相似文献

This study examined the extent to which the validity scales of the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A; Butcher et al., 1992) could identify adolescents who were faking-bad. This study also examined the extent to which the validity scales could differentiate between nonclinical adolescents instructed to fake-bad and both clinical and nonclinical adolescents who received standard instructions. Participants were 58 male and 80 female high school students and 58 male and 80 female adolescents from clinical settings. Results indicated that the mean profiles resembled those previously reported for adults on the MMPI (Graham, 1987) and MMPI-2 (Graham, Watts, & Timbrook, 1991) and for adolescents on the original MMPI (Archer, Gordon, & Kirchner, 1987). Accurate identification of students who were faking-bad was achieved. It was possible to differentiate between the clinical adolescents and nonclinical adolescents who were faking, and it was possible to differentiate between nonclinical adolescents who were faking and nonclinical adolescents with standard instructions; however, different cutoff scores were needed for these two discriminations. Optimal cutoff scores were presented. 相似文献
