An investigation of the psychometric properties of the Eating Disorder Symptom Impact Scale within an Australian sample

Caring for patients with an eating disorder (ED) is associated with a high level of burden and psychological distress. Currently, the Eating Disorder Symptom Impact Scale (EDSIS) is the only scale that measures the specific impact of caring for a patient with an ED. The initial development study within a British sample of carers indicated that the EDSIS has a four‐factor structure. The aim of the current study was to confirm the factor structure of the EDSIS within an Australian sample of carers. One hundred and fifty‐four carers completed the EDSIS. In contrast to the initial study, a six‐factor structure was derived explaining 69.66% of the variance: guilt, social isolation, confrontational behaviours, binge–purge difficulties, mealtime difficulties, and illness awareness. Reliability was acceptable (Cronbach's alpha range 0.69–0.88). Five of the six factors were moderately correlated with the General Health Questionnaire‐12 (r range = 0.24–0.51). A six‐factor solution may be a valid alternative for the EDSIS.     

A temporally sustained implicit theory of mind deficit in autism spectrum disorders

Eye movements during false-belief tasks can reveal an individual’s capacity to implicitly monitor others’ mental states (theory of mind – ToM). It has been suggested, based on the results of a single-trial-experiment, that this ability is impaired in those with a high-functioning autism spectrum disorder (ASD), despite neurotypical-like performance on explicit ToM measures. However, given there are known attention differences and visual hypersensitivities in ASD it is important to establish whether such impairments are evident over time. In addition, investigating implicit ToM using a repeated trial approach allows an assessment of whether learning processes can reduce the ASD impairment in this ability, as is the case with explicit ToM. Here we investigated the temporal profile of implicit ToM in individuals with ASD and a control group. Despite similar performance on explicit ToM measures, ASD-diagnosed individuals showed no evidence of implicit false-belief tracking even over a one-hour period and many trials, whereas control participants did. These findings demonstrate that the systems involved in implicit and explicit ToM are distinct and hint that impaired implicit false-belief tracking may play an important role in ASD. Further, they indicate that learning processes do not alleviate this impairment across the presentation of multiple trials.     

Children's Graffiti: Visual Communication from a Developmental Perspective

The graffiti of children, an unobtrusive measure collected in Puerto Rican natural settings, revealed the children's views about the world. Results show that these graffiti reflect a wide variety of content related to the child's immediate life experiences such as concerns with their self-identity, interpersonal relations, cultural understandings, sexuality, and religious and political beliefs.     

Social Surrogacy and Adjustment: Exploring the Correlates of Having a “Social Helper” for Shy and Non-Shy Young Adolescents

A social surrogate is an individual who offers help and comfort in social situations or makes social events more exciting. In this study of 157 young adolescents (55% female; M_age = 13.84 years, SD = 0.75 years), the authors examined whether the linear and curvilinear associations between self-reported social surrogate use and adjustment outcomes (social problems, loneliness, anxiety symptoms, depressive symptoms) varied as a function of shyness and gender, after accounting for the effects of positive friendship quality. Regression analyses revealed that low and high levels of social surrogate use were related to greater social problems for all adolescents. In addition, shyness emerged as a moderator for several curvilinear effects. Specifically, results indicated that (a) high levels of social surrogate use were associated with greater anxiety for adolescents high in shyness; and (b) low levels of social surrogate use were associated with greater depressive symptoms for adolescents low in shyness. Findings highlight the developmental importance of specific types of relationship experiences during early adolescence and point to different implications of social surrogate use for shy and non-shy young adolescents.     

Risk Factors for Adolescent Marijuana Use Across Cultures and Across Time

An integrated analysis of the data from 3 different studies was conducted to examine the early psychosocial predictors of later marijuana use among adolescents. Longitudinal analysis of interview data was performed. The data used in the analysis were derived from (a) a sample of 739 predominantly White adolescents representative of the northeastern United States, (b) a sample of 1,190 minority adolescents from the East Harlem section of New York City, and (c) a sample of 1,374 Colombian adolescents from two cities in Colombia. South America. In 2 of the samples, participants were interviewed in their homes, and in the 3rd study, participants were assessed in school. The predictors included a number of variables from (a) the personality domain, reflecting the adolescents' conventionality and intrapsychic functioning; (b) the family domain, representing the parent-child mutual attachment relationship and parental substance use; (c) the peer domain, reflecting the peer group's delinquency and substance use; and (d) the adolescents' own use of legal drugs. The dependent variable was adolescent marijuana use. The results of the analysis demonstrated remarkable consistency in the risk and protective factors for later marijuana use across the 3 samples, attesting to the robust nature of these predictors and their generalizability across gender, time, location, and ethnic/cultural background. These findings have important implications for designing intervention programs. Programs aimed at preventing adolescent marijuana use can be designed to incorporate universal features and still incorporate specific components that address the unique needs of adolescents from different groups.     

Attitudes towards psychotherapy manuals among clinicians treating eating disorders

Clinicians have relatively low uptake and implementation of evidence-based psychotherapies for the eating disorders, and this problem appears to be associated with low use of manualized approaches. This study examines clinicians' positive and negative attitudes to manuals, and possible beliefs and emotional factors that might drive those attitudes. The participants were 125 psychological therapists working with eating-disordered patients. Each completed standardised measures of attitudes to manuals and emotional states. A number of beliefs about the content of manuals were associated with both positive attitudes to the outcome of treatment and negative attitudes to their impact on the treatment process. In addition, a more positive mood was associated with more positive attitudes. Suggestions are made regarding how attitudes might be made more positive, in order to facilitate the use of evidence-based therapies for eating disorders.     

Self-help for binge eating disorder in primary care: A randomized controlled trial with ethnically and racially diverse obese patients

Objective

The objective was to examine the effectiveness of a self-help treatment as a first line primary care intervention for binge eating disorder (BED) in obese patients. This study compared the effectiveness of a usual care plus self-help version of cognitive behavioral therapy (shCBT) to usual care (UC) only in ethnically/racially diverse obese patients with BED in primary care settings in an urban center.

Method

48 obese patients with BED were randomly assigned to either shCBT (N = 24) or UC (N = 24) for four months. Independent assessments were performed monthly throughout treatment and at post-treatment.

Results

Binge-eating remission rates did not differ significantly between shCBT (25%) and UC (8.3%) at post-treatment. Mixed models of binge eating frequency determined using the Eating Disorder Examination (EDE) revealed significant decreases for both conditions but that shCBT and UC did not differ. Mixed models of binge eating frequency from repeated monthly EDE-questionnaire assessments revealed a significant treatment-by-time interaction indicating that shCBT had significant reductions whereas UC did not during the four-month treatments. Mixed models revealed no differences between groups on associated eating disorder psychopathology or depression. No weight loss was observed in either condition.

Conclusions

Our findings suggest that pure self-help CBT did not show effectiveness relative to usual care for treating BED in obese patients in primary care. Thus, self-help CBT may not have utility as a front-line intervention for BED for obese patients in primary care and future studies should test guided-self-help methods for delivering CBT in primary care generalist settings.     

Enhancing dissemination in selective eating disorders prevention: An investigation of voluntary participation among female university students

Maximising dissemination of efficacious psychological interventions is an important undertaking, particularly in prevention work where the target population may not be seeking help. Consequently, the current study investigated voluntary participation in a selective eating disorder prevention programme by examining predictors of, and evaluating a motivational enhancement approach to, increased participation. Female students studying first-year psychology (N = 124, M_age = 19.30, SD = 1.55) completed baseline measures, were randomised to a motivational or control condition, then presented with a flyer for an eating disorders prevention trial and assessed regarding potential participation. Results showed that interest and likelihood of participation were low overall and lack of time the most commonly endorsed reason. Participants high on weight concerns were more likely to cite the group format of the intervention as a deterrent. A greater belief in the helpfulness of body image programmes and higher personal ineffectiveness were significant predictors of interest in participation. There was no significant difference between those who did and did not undergo the motivational enhancement with respect to interest and likelihood of participation. These findings suggest important avenues for consideration when designing eating disorder prevention efforts relying on voluntary participation, and highlight the importance of evaluating programmes cross-culturally.     

Psychologists' perspectives on the diagnostic classification of mental disorders: Results from the WHO‐IUPsyS Global Survey

This study examined psychologists' views and practices regarding diagnostic classification systems for mental and behavioral disorders so as to inform the development of the ICD‐11 by the World Health Organization (WHO). WHO and the International Union of Psychological Science (IUPsyS) conducted a multilingual survey of 2155 psychologists from 23 countries, recruited through their national psychological associations. Sixty percent of global psychologists routinely used a formal classification system, with ICD‐10 used most frequently by 51% and DSM‐IV by 44%. Psychologists viewed informing treatment decisions and facilitating communication as the most important purposes of classification, and preferred flexible diagnostic guidelines to strict criteria. Clinicians favorably evaluated most diagnostic categories, but identified a number of problematic diagnoses. Substantial percentages reported problems with crosscultural applicability and cultural bias, especially among psychologists outside the USA and Europe. Findings underscore the priority of clinical utility and professional and cultural differences in international psychology. Implications for ICD‐11 development and dissemination are discussed.     

Observational Learning and the Role of Confinement in Pigeons: Suppression of Learning as a Function of Observing the Performance of a Conspecific

Observational learning of a successive discrimination problem by pigeons was studied using conspecifics as models responding for either contingent or noncontingent reinforcement. We found that observation of these models was associated with poorer performance on subsequent testing than was shown by a control group that learned without first observing conspecifics' performance. No significant difference was found between subjects without observational experience and another control group that was confined in the observation apparatus and observed an empty chamber only.
