Screening for eating disorders in primary care: EDE-Q versus SCOFF

OBJECTIVE AND METHODS: The comparative validity of the Eating Disorder Examination Questionnaire (EDE-Q) (22 items) and SCOFF (five items) in screening for cases of the more commonly occurring eating disorders was examined in a primary care sample of young adult women (n=257). Diagnoses were confirmed in a sub-group of interviewed participants (n=147). RESULTS: Twenty-five cases, primarily variants of bulimia nervosa (BN) not meeting formal diagnostic criteria, were identified in the interviewed sample. An EDE-Q global score of >or= 2.80 yielded the optimal trade-off between sensitivity (Se) (0.80) and specificity (Sp) (0.80) (positive predictive value (PPV)=0.44), whereas a score of two or more positive responses on the SCOFF was optimal (Se=0.72, Sp=0.73, PPV=0.35). Validity coefficients for both measures varied as a function of participants' age and body weight, although these effects were more pronounced for the SCOFF. CONCLUSIONS: Both measures performed well in terms of their ability to detect cases and to exclude non-cases of the more commonly occurring eating disorders in a primary care setting. The EDE-Q performed somewhat better than the SCOFF and was more robust to effects on validity of age and weight. These findings need to be weighed against the advantage of the SCOFF in terms of its brevity.     

Individual Differences in Attitudes Relevant to Juror Decision Making: Development and Validation of the Pretrial Juror Attitude Questionnaire (PJAQ)1

This study involves scale development using theoretically derived items from previous measures and a lay consensual approach for generating new items. Confirmatory factor analysis was used to validate the emergent constructs assessing individual differences in attitudes of prospective jurors. Using case summaries, the Pretrial Juror Attitude Questionnaire (PJAQ) demonstrates superior predictive validity over commonly employed measures of pretrial bias. The PJAQ confirms the importance of theoretically derived constructs assessed by other scales and introduces new constructs to the jury decision‐making literature. The attitudes assessed by the PJAQ are conviction proneness, system confidence, cynicism toward the defense, racial bias, social justice, and innate criminality. Implications for assessing such attitudes and for better understanding the decision‐making process of jurors are discussed.     

Defensiveness and attempted thought suppression of negative material

High and low defensive individuals engaged in attempted thought suppression and non‐suppression after viewing an emotionally stressful piece of film. As a function of suppression and non‐suppression instructions, high and low defensive individuals differed from each other in the number of reported film‐related thoughts. Suppression instructions had greatest effects on low defensive individuals in reducing the number of reported film‐related thoughts. The effects of suppression instructions were not significant in reducing the number of film‐related thoughts for high defensive individuals. High defensive individuals also reported more neutral thoughts under the suppression condition compared with the non‐suppression condition. Low defensive individuals reported similar numbers of neutral thoughts under the two conditions. Effects of suppression instructions were investigated in a subsequent cognitive task that measured the level of interference produced by attempted suppression. Suppression instructions did not significantly effect the cognitive processing of participants. Theoretical and methodological implications for understanding the possible cognitive structures underlying attempted suppression are discussed in terms of the effects of defensiveness.

Victim Impact Testimony and Juror Judgments: The Effects of Harm Information and Witness Demeanor1

Victim impact testimony (i.e., testimony concerning the harmful consequences on the victim's surviving family) was examined to determine its effect on the sentencing judgments of mock jurors. Undergraduate students (N= 293) watched a videotaped murder trial simulation, rendered verdicts, and made sentencing judgments. During the penalty phase of the trial, participants were either given no victim impact testimony, or they were given victim impact testimony that varied both the severity of the harm information (mild harm/ severe harm) and the demeanor of the witness (low affect/high affect). The results indicate that information concerning the harm experienced by the victim's relatives, not the affective demeanor of the witness, influenced sentencing judgments. Implications for the U.S. Supreme Court decision in Payne v. Tennessee (1991) are discussed.     

A comparison of latent inhibition and learned irrelevance pre-exposure effects in rabbit and human eyeblink conditioning

The learning of an association between a CS and a US can be retarded by unreinforced presentations of the CS alone (termed latent inhibition or LI) or by un-correlated presentations of the CS and US (termed learned irrelevance or LIRR). In rabbit eyeblink conditioning, there have been some recent failures to replicate LI. LIRR has been hypothesized as producing a stronger retardation effect than LI based on both empirical studies and computational models. In the work presented here, we examined the relative strength of LI and LIRR in eyeblink conditioning in rabbits and humans. In both species, a number of pre-exposure trials sufficient to produce LIRR failed to produce LI (Experiments 1 & 3). Doubling the number of CS pre-exposures did produce LI in rabbits (Experiment 2), but not in humans (Experiment 4). LI was demonstrated in humans only after manipulations including an increased inter-trial interval or ITI (Experiment 5). Overall, it appears that LIRR is a more easily producible pre-exposure retardation effect than LI for eyeblink conditioning in both rabbits and humans. Several theoretical mechanisms for LI including the conditioned attention theory, stimulus compression, novelty, and the switching theory are discussed as possible explanations for the differences between LIRR and LI. Overall, future work involving testing the neural substrates of pre-exposure effects may benefit from the use of LIRR rather than LI.     

Individual Orientation Toward Engagement in Social Action

The issue of how an activist identity develops is one of the core issues in social psychology and social movement research. Because of problems in the measurement of individuals' propensities to engage in social action, however, findings in this area are often equivocal, and cross–study comparisons and conclusions are difficult to draw. Hence, the aim of these studies was to develop a measure to assess individuals' propensities to engage in social action. This measure, the Activism Orientation Scale (AOS), demonstrates strong psychometric properties and allows assessment of activist propensity across a wide continuum of social action behaviors, ideological positions, and movement issues. Additionally, the broad applicability of the AOS allows for its use by researchers, activists, and policymakers.     

Acquired Equivalence Changes Stimulus Representations

Acquired equivalence is a paradigm in which generalization is increased between two superficially dissimilar stimuli (or antecedents) that have previously been associated with similar outcomes (or consequents). Several possible mechanisms have been proposed, including changes in stimulus representations, either in the form of added associations or a change of feature salience. A different way of conceptualizing acquired equivalence is in terms of strategic inference: Confronted with a choice on which it has no evidence, the organism may infer from its history of reinforcement what the best option is, and that inference is observed as acquired equivalence. To test this account, we combined an incremental learning task with an episodic memory test. Drawings of faces were made equivalent through acquired equivalence training, and then paired with words in a list learning paradigm. When participants were asked to recognize specific face-word pairings, they confused faces more often when they had been made equivalent. This suggests that prior acquired equivalence training does influence how memories are coded. We also tested whether this change in coding reflected acquisition of new associations, as suggested by the associative mediation account, or whether stimuli become more similar through a reweighting of stimulus features, as assumed by some categorization theories. Results supported the associative mediation view. We discuss similarities between this view and exemplar theories of categorization performance.     

Marital Status and Outcome in Patients with Coronary Heart Disease

The purpose of this study was to examine the relationship of marital status to health outcomes in 818 post-MI, coronary artery bypass surgery, and angioplasty patients (651 males, 157 females) from seven Northern California hospitals who completed 12 months of a nurse-managed, home-based multifactorial risk reduction program. Compared to married patients, nonmarried patients were significantly less likely to complete the program than married patients, more likely to smoke at baseline, and drank significantly less alcohol at baseline. At 12 months there were no significant differences between married and nonmarried groups on smoking cessation rates, HDL, LDL, triglycerides, or exercise treadmill test results. When patients were categorized as married, divorced, separated, widowed, or single, similar results were found for the analyses using two groups (married versus nonmarried), with the following exceptions. Separated patients were significantly less likely to quit smoking. In addition, separated patients showed significantly higher rates of starting (and continuing) to smoke during the time following their MI. Mortality was not significantly different between married and unmarried patients. Implications for intervention with separated patients and the importance of assessing both marital status and marital quality are discussed.
