The Physical Appearance Ambiguous Feedback Scale (PAAFS): a measure for indexing body image related cognitive bias

Recent conceptualizations of body image disturbance have included an information processing model that includes a focus on an interpretive information processing bias. Study 1 involved the development and validation of a measure of appearance-based cognitive bias, the Physical Appearance Ambiguous Feedback Scale (PAAFS). In Studies 2 and 3, two samples of college females (n=313) were tested and the psychometric characteristics of the PAAFS were evaluated. Reliability was acceptable and convergence with measures of body image and eating disturbance was moderate. In Study 4, 313 college females completed the PAAFS in the laboratory based on an instructional content designed to induce processing bias. Preliminary evidence indicates that the PAAFS appears to be sensitive to instructional set manipulations and dispositional level of body dissatisfaction.     

The effects of extinction,noncontingent reinforcement and differential reinforcement of other behavior as control procedures

Several techniques have been used in applied research as controls for the introduction of a reinforcement contingency, including extinction, noncontingent reinforcement (NCR), and differential reinforcement of other behavior (DRO). Little research, however, has examined the relative strengths and limitations of these "reversal" controls. We compared the effects of extinction with those of NCR and DRO in both multi-element and reversal designs, with respect to (a) rate and amount of response decrement, (b) rate of response recovery following reintroduction of reinforcement, and (c) any positive or negative side effects associated with transitions. Results indicated that extinction generally produced the most consistent and rapid reversal effects, with few observed negative side effects.     

The effects of presession attention on problem behavior maintained by different reinforcers

The effect of presession attention on the later occurrence of problem behavior was examined with elementary-school children with a range of disabilities. Results of analogue functional analyses suggested an escape function, an attention function, or both. Following the analogue functional analyses, the effects of two antecedent conditions (10-min ignore vs. 10-min attention) were compared on problem behavior in subsequent test conditions. For participants who displayed attention-maintained problem behavior, the test condition involved contingent attention for problem behavior. For participants who displayed escape-maintained problem behavior, the test condition involved contingent escape for problem behavior. Results indicated that participants who displayed attention-maintained problem behavior displayed less problem behavior following presession exposure to attention than when ignored. No such effect was found for presession attention on escape-maintained problem behavior. We discuss matching antecedent-based interventions to the results of functional analysis.     

When is early visual cortex activated during visual mental imagery?

Although many neuroimaging studies of visual mental imagery have revealed activation in early visual cortex (Areas 17 or 18), many others have not. The authors review this literature and compare how well 3 models explain the disparate results. Each study was coded 1 or 0, indicating whether activation in early visual cortex was observed, and sets of variables associated with each model were fit to the observed results using logistic regression analysis. Three variables predicted all of the systematic differences in the probability of activation across studies. Two of these variables were identified with a perceptual anticipation theory, and the other was identified with a methodological factors theory. Thus, the variability in the literature is not random.     

Group identification moderates emotional responses to perceived prejudice

Two studies tested the prediction that group identification (importance of the group in the self-concept) moderates the impact of perceived discrimination on self-evaluative emotions (depression and self-esteem). In Study 1, women low in gender identification experienced less depressed emotion and higher self-esteem if a negative evaluation was due to sexism than when it was not. The self-evaluative emotions of women high in gender identification were not buffered by attributions to sexism. In Study 2, ethnic identification and depressed emotions were positively related when Latino-Americans read about pervasive prejudice against the ingroup but were negatively related when they read about prejudice against an outgroup. Both studies demonstrated that for highly group identified individuals, prejudice against the ingroup is a threat against the self. Thus, the self-protective strategy of attributing negative feedback to discrimination may be primarily effective for individuals who do not consider the group a central aspect of self.     

It's not my fault: when and why attributions to prejudice protect self-esteem

This study tested the hypothesis that awareness of the possibility of being a target of discrimination can provide individuals with a means of self-esteem protection when they are faced with negative outcomes. Men and women contemplated being rejected from a course due to sexism, personal deservingness, or an exclusively external cause. Regardless of gender, participants in the sexism condition blamed themselves less, attributed the rejection less to internal causes, and anticipated feeling less depressed than those in the personal deservingness condition. Furthermore, the more participants discounted the rejection--blamed it more on discrimination than themselves--the less depressed emotions they anticipated feeling. Discounting did not buffer participants from feeling hostility or anxiety. These findings advance our understanding of when and why attributions to prejudice protect emotional well-being.     

A population-based study of the association between pathological gambling and attempted suicide

The association between pathological gambling and attempted suicide was examined using data from a prevalence study conducted in Edmonton, Alberta, Canada. The sample size was 7,214, the questionnaire was the Diagnostic Interview Schedule, and diagnoses were made on a lifetime basis according to DSM-III criteria. Logistic regression analysis was performed, with attempted suicide as the dependent variable. The odds ratio for pathological gambling was statistically significant (odds ratio = 4.91; 95% confidence interval = [1.41,17.1]) when major depression was the only comorbid mental disorder in the model. As terms for additional mental disorders were included, pathological gambling ceased to be statistically significant. It was concluded that a history of pathological gambling is associated with previous attempted suicide, and that the association may be due to a common factor--"mental illness."     

Examining the construct validity of the Eating Disorder Inventory

The construct validity of the Eating Disorder Inventory (EDI) was examined in 3 samples. An archival clinic sample (n = 318) of women completed the EDI, a structured interview, and the Millon Clinical Multiaxial Inventory-II (MCMI-II). Confirmatory factor analyses (CFAs) indicated that neither null nor 1-factor models of the EDI fit item-level or item-parcel data. The proposed 8-factor model did not fit at the item level but did fit item-parcel data. Reliability estimates of the 8 scales ranged from .82 to .93, and low-to-moderate interscale correlations among the eating and weight-related scales provided partial support for convergent validity. EDI personality scales showed moderate interscale correlations and were associated with MCMI-II scales. A final CFA of the EDI scales supported a 2-factor model (Eating and Weight, Personality) of the 8 EDI scales. Strong associations between depression and several EDI scale scores were found in a treatment study sample (n = 50). The archival clinic sample scored significantly higher on the 8 EDI scales than the nonpatient college comparison sample (n = 487).     

Test anxiety, coping strategies, and perceived health in a group of high school students: a Turkish sample

A group of high school juniors and a group of high school seniors in Izmir, Turkey completed measures of test anxiety, coping skills, and perceived health status both before and after a major exam period. Students with high test anxiety used less effective coping mechanisms and tended to have poorer perceptions of their health. Prior to the exams, juniors displayed higher test anxiety and used less effective coping mechanisms than seniors. After the exam periods, improvements were seen for both age groups on perceived health, but scores of younger students remained significantly higher than scores of seniors on one of the key measures of test anxiety. Results of the study lend support to those of previous studies done in other cultural contexts, and findings have implications for the development of interventions designed to help students cope with stress.
