We implemented a pyramidal training procedure for staff working with individuals who exhibited self-injurious behavior (SIB), aggression, and disruption. Two adults with developmental disabilities and their direct-care staff and supervisors participated. Following successful treatment by the experimenters, two types of baselines were conducted with the clients and their direct-care staff. During an initial baseline, the staff implemented preexisting procedures. Staff members then received instruction on the new treatment procedures using training methods common throughout the institution, and data were collected during this “post-in-service” baseline. Experimenters then taught unit supervisors to implement treatment, collect and interpret data, and provide similar instructions and feedback to the staff members. The supervisor training was implemented in a multiple baseline design across subjects (clients and direct-care staff). Results showed little change following in-service training but noticeable improvements in direct-care staff behaviors and corresponding decreases in the clients' inappropriate behavior following the pyramidal training intervention with supervisors. Six additional clients (along with their direct-care staff and supervisors) participated in pre- and posttreatment replication designs, and their results provided additional support for the efficacy of the supervisor training procedures. 相似文献

McCarthy (1990) contends that a cultural ideal of thinness (the thin ideal) causes depression and eating disorders to occur more frequently in women than men. She believes eating disorders are a way of coping with depression and hypothesizes that the thin ideal has its greatest impact during puberty when sexual attractiveness becomes important and changes in physical appearance increase the discrepancy between the adolescent girl's actual and ideal body image. The present study used a cross-sectional design of 5th, 8th, and 12th grade males and females (N = 599) to test several predictions from McCarthy's model. As expected, 8th and 12th grade females preferred a thinner than average body shape. They were more dissatisfied with their bodies than males and scored higher on measures of disordered eating. In contrast, before puberty (5th grade) boys were more depressed than their female peers but this pattern was reversed in 8th grade boys and girls. Paralleling changes in depression, disordered eating scores were highest in 8th and 12th grade girls. Both of these findings underscore the role of maturational factors in the onset of eating disorders. Although the sample was ethnically diverse and mainly from middle and low socioeconomic groups, there was a surprisingly high incidence of body dissatisfaction and symptoms of disordered eating. This illustrates the pervasiveness of thinness as a standard of feminine beauty in our society and the damaging effects it can have. 相似文献

Recent studies have found that the eating disorders can best be conceptualized as multidimensional. Four factors have consistently emerged from factor analytic studies of eating disorder symptoms: dietary restraint, bulimic behaviors, neurotic personality characteristics, and body image/body dysphoria. Confirmatory factor analysis was utilized to determine if this four-factor structure of eating disorder symptoms would be found in a sample of college women. Principal components analysis extracted four factors which were supported with a confirmatory factor analysis procedure. These four factors were negative affect and body dysphoria, bulimic behaviors, restrictive eating, and body image. The negative affect and body dysphoria factor was positively correlated with the other factors (i.e., bulimic behaviors, restrictive eating, and body image). This factor structure was similar to the factor structure found in samples of patients with bulimia and anorexia nervosa, except that the factors were more highly intercorrelated in the nonclinical sample. Results suggest that the measures of eating disorder symptoms used in this investigation are measuring the same multidimensional constructs in clinical and nonclinical subjects.This paper is partially based upon the master's thesis of the first author. 相似文献

There has been considerable controversy regarding a possible sex bias in the diagnosis of personality disorders (PDs). However, prior research has at times confused a bias within clinicians who fail to adhere to the diagnostic criteria with a bias within the diagnostic criteria. Rather than assess whether females are more likely than males to be diagnosed with a respective disorder, the current study assesses whether the thresholds for the diagnosis of female-typed PDs are lower than the thresholds for male-typed PDs. Subjects completed two self-report inventories for the DSM-III-R personality disorders, and three inventories that assessed 30 aspects of personality dysfunction organized with respect to social dysfunction, occupational dysfunction, and personal distress. There was no indication that the diagnostic thresholds for personality disorders that occur more often in females is lower than the thresholds for the personality disorders that occur more often in males. The implications of these findings for the issue of sex biased diagnoses are discussed. 相似文献

This paper investigates whether changes in mood state are an important component of cognitive bias modification (CBM) procedures. In a novel CBM procedure participants read either positive or negative statements relating to social issues for 5 min. Interpretation bias was measured by means of a scrambled sentence test, which was presented both before and after the CBM procedure. Participants who read the positive statements made more positive resolutions to the scrambled sentences, while participants who read the negative statements made more negative resolutions. Thus, the appropriate positive and negative interpretative biases were induced by the CBM procedure. However, significant mood changes also occurred following CBM. In Experiment 2, a musical mood induction procedure was presented with depressing or elating music. As before, a scrambled sentence test was presented both before and after the musical mood induction. Mood changed in accordance with the valence of the music to the same extent as with CBM. Critically however, performance on the scrambled sentence task did not change for both groups. This demonstrates that a change in mood state is not sufficient for a change in cognitive bias to occur. 相似文献

The present study examines the extent to which attentional biases in contamination fear commonly observed in obsessive-compulsive disorder (OCD) are specific to disgust or fear cues, as well as the components of attention involved. Eye tracking was used to provide greater sensitivity and specificity than afforded by traditional reaction time measures of attention. Participants high (HCF; n = 23) and low (LCF; n = 25) in contamination fear were presented with disgusted, fearful, or happy faces paired with neutral faces for 3 s trials. Evidence of both vigilance and maintenance-based biases for threat was found. The high group oriented attention to fearful faces but not disgusted faces compared to the low group. However, the high group maintained attention on both disgusted and fearful expressions compared to the low group, a pattern consistent across the 3 s trials. The implications of these findings for conceptualizing emotional factors that moderate attentional biases in contamination-based OCD are discussed. 相似文献

Affective lability has been linked to several maladaptive behaviors (
[Anestis et?al., 2009] and [Coccaro, 1991]). Methodology for measuring affective lability varies and includes retrospective self-report and ecological momentary assessment (EMA). In this study, we sought to test these methodologies by examining which better predicted binge eating episodes and general eating disorder symptoms in a sample (n = 131) of women diagnosed with bulimia nervosa (BN). We hypothesized that, while the two forms of measurement would be correlated with one another and predict binge eating episodes, EMA affective lability would be the stronger predictor. Results supported several hypotheses. Specifically, both EMA affective lability and retrospective self-report affective lability significantly predicted global eating disorder symptoms, even when controlling for depression, age, body mass index, and level of education, EMA affective lability exhibited a significantly stronger correlation with binge eating episodes than did retrospective self-report affective lability, and EMA affective lability predicted number of binge eating episodes on any given day controlling for the same list of covariates. Limitations include the use of a clinical sample that may limit the generalizability of our findings. Findings highlight the importance of affect in such behavior. 相似文献

The majority of research in eating disorders (ED) has investigated the content of disorder-specific thoughts, while few studies have addressed underlying cognitive-affective processes. A better understanding of processes underpinning ED may have important implications for treatment development. Two studies were conducted that investigated levels of rumination, beliefs about rumination, experiential avoidance, and aspects of schematic thinking in individuals with eating pathology. The latter was assessed with a newly designed ED-Sentence Completion Task (ED-SCT). Study 1 (N = 177) examined relations between ED psychopathology and these variables in a student population. Extending this, Study 2 (N = 26) assessed differences between patients with anorexia nervosa and healthy control participants. The results showed that ED psychopathology was related to disorder-specific cognitions, experiential avoidance as well as ruminative brooding but not reflection. A follow-up of anorexia nervosa patients indicated that changes in ED psychopathology were associated with changes in dysfunctional attitudes and maladaptive cognitive-affective processes. These findings highlight cognitive processes that may play an important role in the maintenance of eating pathology. 相似文献
