Clarifying boundaries of binge eating disorder and psychiatric comorbidity: a latent structure analysis

Binge eating disorder (BED) presents with substantial psychiatric comorbidity. This latent structure analysis sought to delineate boundaries of BED given its comorbidity with affective and anxiety disorders. A population-based sample of 151 women with BED, 102 women with affective or anxiety disorders, and 259 women without psychiatric disorders was assessed with clinical interviews and self-report-questionnaires. Taxometric analyses were conducted using DSM-IV criteria of BED and of affective and anxiety disorders. The results showed a taxonic structure of BED and of affective and anxiety disorders. Both taxa co-occurred at an above-chance level, but also presented independently with twice-as-large probabilities. Within the BED taxon, diagnostic co-occurrence indicated greater general psychopathology, lower social adaptation, and greater premorbid exposure to parental mood and substance disorder, but not greater eating disorder psychopathology. Eating disorder psychopathology discriminated individuals in the BED taxon from individuals in the affective and anxiety disorders taxon. Diagnostic criteria of BED were more indicative of the BED taxon than were criteria of affective and anxiety disorders. The results show that at the latent level, BED was co-occurring with, yet distinct from, affective and anxiety disorders and was not characterized by an underlying affective or anxiety disorder.     

A test of written emotional disclosure as an intervention for posttraumatic stress disorder

This study examined the efficacy of the written emotional disclosure (WED) procedure with a sample of young adults who met diagnostic criteria for posttraumatic stress disorder (PTSD). Participants were randomly assigned to either WED or a control writing condition and were assessed at baseline and one month following the writing sessions. During each writing session, participants’ heart rate was recorded; participants also provided self-report ratings of emotional responding. Findings indicated no significant group differences for PTSD and depression symptom severity at follow-up assessment. Relative to control participants, WED participants displayed significantly greater heart rate activity and reported greater emotional responding during the first writing session; however, no reduction in emotional responding occurred for either condition from the first to the last writing session. Taken together, these findings indicate that WED may not be an efficacious intervention for PTSD. Suggestions are made for future work in this area.     

Using multiple-exemplar training to teach a generalized repertoire of sharing to children with autism

The current study examined the utility of multiple-exemplar training to teach children with autism to share. Stimuli from 3 of 4 categories were trained using a treatment package of video modeling, prompting, and reinforcement. Offers to share increased for all 3 children following the introduction of treatment, with evidence of skill maintenance. In addition, within-stimulus-category generalization of sharing was evident for all participants, although only 1 participant demonstrated across-category generalization of sharing. Offers to share occurred in a novel setting, with familiar and novel stimuli, and in the presence of novel adults and peers for all participants during posttreatment probes.     

Expressive writing buffers against maladaptive rumination

This study examined whether ruminative style moderated the effects of expressive writing. Sixty-nine participants were assessed for ruminative style and depression symptoms at the beginning of their 1st college semester. Participants were then randomized to either an expressive writing or a control writing condition. Changes in depression symptoms were assessed 2, 4, and 6 months later. Results showed that a brooding ruminative style moderated the effects of expressive writing such that among those assigned to the expressive writing condition, individuals with greater brooding scores reported significantly fewer depression symptoms at all of the follow-up assessments relative to individuals with lower brooding scores. In contrast, reflective pondering ruminative style did not moderate the effects of expressive writing on depression symptoms. These findings suggest that expressive writing could be used as a means of reducing depression symptoms among those with a maladaptive ruminative tendency to brood.     

Implicit stereotypes, gender identification, and math-related outcomes: a prospective study of female college students

This study examined the effects of gender identification and implicit and explicit gender stereotyping among undergraduate women enrolled in college-level calculus courses. Women's gender identification and gender stereotyping regarding math aptitude were assessed after the course's first midterm exam. Implicit, but not explicit, stereotyping interacted with gender identification to affect women's performance on their final exams and their desire to pursue math-related careers. Women who showed low gender identification and low implicit gender stereotyping performed best on the final exam, and women with high scores on both factors were the least inclined to pursue math-based careers. Implications for the underrepresentation of women in math and the hard sciences are discussed.     

Abusive supervision, intentions to quit, and employees’ workplace deviance: A power/dependence analysis

We conducted a two-study examination of relationships between abusive supervision and subordinates’ workplace deviance. Consistent with predictions derived from power/dependence theory, the results of a cross-sectional study with employees from three organizations suggest that abusive supervision is more strongly associated with subordinates’ organization deviance and supervisor-directed deviance when subordinates’ intention to quit is higher. The results also support the prediction that when intention to quit is higher, abusive supervision is more strongly associated with supervisor-directed deviance than with organization-directed deviance. These results were replicated in a second study, a two-wave investigation of people employed in a variety of industries and occupations.     

Fear-Related Chemosignals Modulate Recognition of Fear in Ambiguous Facial Expressions

ABSTRACT— Integrating emotional cues from different senses is critical for adaptive behavior. Much of the evidence on cross-modal perception of emotions has come from studies of vision and audition. This research has shown that an emotion signaled by one sense modulates how the same emotion is perceived in another sense, especially when the input to the latter sense is ambiguous. We tested whether olfaction causes similar sensory modulation of emotion perception. In two experiments, the chemosignal of fearful sweat biased women toward interpreting ambiguous expressions as more fearful, but had no effect when the facial emotion was more discernible. Our findings provide direct behavioral evidence that social chemosignals can communicate emotions and demonstrate that fear-related chemosignals modulate humans' visual emotion perception in an emotion-specific way—an effect that has been hitherto unsuspected.     

Making plans for healthy diet: The role of motivation and action orientation

The main objective of the present study was to examine the role of motivation and action orientation in forming spontaneous (i.e., without specific instruction or manipulation) implementation intentions for a healthy diet goal. We hypothesized that (1) the adoption of a diet goal would be determined by (either intrinsic or extrinsic) motivation only whereas, (2) forming implementation intentions would be determined by intrinsic motivation and (either low or high) action orientation. These hypotheses were addressed in a sample of 142 normal weight subjects who were concerned about their dietary habits. Primary outcomes were goal intentions and implementation intentions. Our hypothesis regarding the prediction of goal intentions was confirmed whereas results relating to the prediction of implementation intentions demonstrated that intrinsic motivation and low (but not high) action orientation proved significant predictors of intentions to implement a healthy diet goal. These findings suggest that self‐regulatory skills as assessed by the concept of action orientation may relate to short‐term strategies of initiating behavior change only.
