Emotions mediate the relationship between autistic traits and disordered eating: a new autistic-emotional model for eating pathology

The aim of the study was to assess the extent of overlap between autistic traits, body dissatisfaction and disordered eating and to explore the mediating effects of negative attitudes towards emotional expression and emotion dysregulation. The sample comprised 416 university students (82% females, 17-48 years [M=19.76, SD=3.85]), who completed an online questionnaire assessing eating attitudes and behaviours (including dieting, bulimia and oral control), body dissatisfaction, and autistic traits (including the Autism Quotient [AQ] and its related subscales as well as the Empathising Quotient). Attitudes towards emotional expression and emotion regulation were also assessed. Results revealed that eating pathology correlated highly with all AQ subscales, with the exception of the attention to detail subscale. However, there was no significant relationship between empathising and eating pathology. Path-analyses indicated that emotion dysregulation, but not negative attitudes towards emotional expression, was a significant mediator of the relationship between AQ, body dissatisfaction and eating pathology. Direct relationships were also obtained for the AQ-bulimia and the AQ-oral control paths. Prevention and early intervention programs for eating pathology would likely benefit from addressing abnormalities in emotion processes in individuals who score highly on measures of autistic traits.

Predictors of outcomes of psychological treatments for disordered gambling : a systematic review

This systematic review aimed to synthesise the evidence relating to pre-treatment predictors of gambling outcomes following psychological treatment for disordered gambling across multiple time-points (i.e., post-treatment, short-term, medium-term, and long-term). A systematic search from 1990 to 2016 identified 50 articles, from which 11 socio-demographic, 16 gambling-related, 21 psychological/psychosocial, 12 treatment, and no therapist-related variables, were identified. Male gender and low depression levels were the most consistent predictors of successful treatment outcomes across multiple time-points. Likely predictors of successful treatment outcomes also included older age, lower gambling symptom severity, lower levels of gambling behaviours and alcohol use, and higher treatment session attendance. Significant associations, at a minimum of one time-point, were identified between successful treatment outcomes and being employed, ethnicity, no gambling debt, personality traits and being in the action stage of change. Mixed results were identified for treatment goal, while education, income, preferred gambling activity, problem gambling duration, anxiety, any psychiatric comorbidity, psychological distress, substance use, prior gambling treatment and medication use were not significantly associated with treatment outcomes at any time-point. Further research involving consistent treatment outcome frameworks, examination of treatment and therapist predictor variables, and evaluation of predictors across long-term follow-ups is warranted to advance this developing field of research.

Benzodiazepine use of community-based violent offenders : a preliminary investigation

Objective: To explore the relationship between benzodiazepine use and violent crime in a sample of community-based offenders. Methods: Participants were recruited via drug diversion and treatment programs in Melbourne, Australia. Data regarding benzodiazepine and other substance use, mental health, personality characteristics, and crime involvement were collected through semistructured interviews conducted in 2011. Participants (n = 82, 79.3% male) were 21–56 years old, predominantly Australian-born (89%), with 14.6% identifying as Aboriginal or Torres Strait Islanders. Eligibility criteria were having been charged with a criminal offence in the previous six months and at least monthly benzodiazepine use. Group differences between violent (n = 11) and nonviolent offenders were assessed via independent samples t-tests (two-tailed) and nonparametric tests. Results: Individuals charged with violent index offences were significantly more likely to use higher average doses of alprazolam (p = 0.040) and exhibit benzodiazepine dependence (p = 0.037) as well as report high levels of sensation seeking, prior violence, and the diagnoses of depression and personality disorder than individuals charged with nonviolent index offences. Conclusions: The findings suggest the existence of a complex dynamic between mental health and violent offending that may be influenced by benzodiazepine use, in particular alprazolam. A core implication of these preliminary findings includes attending to the interpersonal skills and adaptive coping resources of violent offenders.
