A Pilot Study of a Functional Contextual Treatment for Bulimia Nervosa

This paper describes the initial development of a treatment for bulimia nervosa using a functional contextual treatment approach. Seven women (6 with a diagnosis of bulimia nervosa and 1 with a diagnosis of eating disorder not otherwise specified) completed 12 sessions of functional contextual treatment. Participants were assessed with the Eating Disorders Examination at baseline and following treatment. The intervention produced significant reductions in binge eating, purgative behavior, dietary restraint, and eating concerns. A functional contextual treatment holds promise for the treatment of bulimia nervosa. However, the treatment needs to be refined further and will need to be tested in controlled clinical trials with long-term follow-up.     

Prototype Personality Diagnosis in Clinical Practice: A Viable Alternative for DSM-V and ICD-11

Several studies suggest that a prototype matching approach yields diagnoses of comparable validity to the more complex diagnostic algorithms outlined in DSM-IV. Furthermore, clinicians prefer prototype diagnosis of personality disorders (PDs) to the current categorical diagnostic system or alternative dimensional methods. An important extension of this work is to investigate the degree to which clinicians are able to make prototype diagnoses reliably. The aim of this study is to assess the inter-rater reliability of a prototype matching approach to personality diagnosis in clinical practice. Using prototypes derived empirically in prior research, outpatient clinicians diagnosed patients' personality after an initial evaluation period. External evaluators independently diagnosed the same patients after watching videotapes of the same clinical hours. Inter-rater reliability for prototype diagnosis was high, with a median r = .72. Cross-correlations between disorders were low, with a median r = .01. Clinicians and clinically trained independent observers can assess complex personality constellations with high reliability using a simple prototype matching procedure, even with prototypes that are relatively unfamiliar to them. In light of its demonstrated reliability, efficiency, and versatility, prototype diagnosis appears to be a viable system for DSM-V and ICD-11 with exceptional utility for research and clinical practice.     

TWO MEASURES OF PREFERENCE DURING FORCED-CHOICE ASSESSMENTS

A forced-choice preference assessment was conducted in which two dependent measures were used to select preferred stimuli: (a) approach responding and (b) latency to the first aberrant response. Stimuli identified as preferred based on both dependent measures were then evaluated during treatment. The results suggested that latency may be a useful measure in the selection of preferred stimuli during forced-choice assessments.     

Intergroup Ratio and the Contact Hypothesis1

This study assessed whether contact between members of 2 social groups generalized to contact in another setting, as well as influenced their intercultural knowledge and acceptance. Subjects were 244 international (mainly ethnic Chinese) and Anglo-Australian students living in 3 student residence halls, with each group comprising a numerical majority, equal proportion, and a numerical minority in one of the residential halls. As anticipated, group ratio exerted a systematic effect on the amount of intercultural contact, with most contact by members of a numerical minority, regardless of student group. Importantly, the pattern of residence-hall contact tended to generalize to the wider university environment and to influence intercultural knowledge and acceptance. However, contact was not unqualified in its effects, particularly in relation to members of the cultural majority.     

Working memory capacity predicts search accuracy for novel as well as repeated targets

Visual search behaviour is guided by mental representations of targets that direct attention toward relevant features in the environment. Electrophysiological data suggests these target templates are maintained by visual working memory during search for novel targets and rapidly transfer to long term memory with target repetition. If this account is correct, an individual’s working memory capacity should be more predictive of search performance for novel targets than repeated targets. Across six experiments, we tested this hypothesis using both single (Experiments 5 and 6) and multiple (Experiments 1–4) target search tasks with three different types of stimuli (real world objects, letters, and triple conjunction shapes). Each target set was repeated for six consecutive trials. In addition, we estimated visual working memory capacity using a change detection working memory task. Overall, working memory capacity did not predict response time or efficiency in the visual search task. However, working memory capacity was equally predictive of search accuracy for both novel and repeated targets. These results suggest that working memory requirements do not substantially differ between novel and repeated target search, and working memory capacity may continue to play an important role in the encoding or maintenance of target representations after they are presumed to be in long term memory.     

The effects of a wisdom intervention in a Christian congregation*

Psychological research on the topic of wisdom is limited in its incorporation of religion and spirituality. This gap in psychological literature may serve to limit a thorough understanding of wisdom. Positive psychology may allow for some rapprochement in wisdom and spirituality. In collaboration with leaders of a local Friends (Quaker) congregation, two studies investigated the effects of a spiritually informed wisdom intervention delivered in the context of a faith community. Participants for Study 1 consisted of 27 young adults (24 completed both the pre and post questionnaire) and a comparison group consisting of 32 young adults. The intervention was designed to increase participants’ abilities in cognitive, affective and moral domains. Significant group by time interaction effects were found among measurements of practical wisdom, post-formal thinking and subjective well-being, with those in the experimental group showing changes in the expected direction. Study 2 involved qualitative analyses of interviews with 15 of the wisdom participants regarding their changing views of wisdom. Themes emerging from the interviews included a multiple-perspectives view of wisdom, the relational nature of learning wisdom, the importance of taking a reflective perspective, and congruence between what one knows and how one lives. Implications for studying wisdom alongside religion and spirituality are considered.
