Perfectionism has adverse impacts on mental health and academic outcomes. We evaluated a 5-lesson classroom intervention for young adolescents delivered by teachers for impact on perfectionism, well-being, self-compassion, academic motivation and negative affect, at post-intervention and 3-month follow-up. Classes (N = 636 students, M[subscript age] = 13.68, SD = 0.60) were randomized to intervention (n = 343) or classes as usual (n = 293). Data were analyzed using linear mixed models adjusted for baseline observation and clustering. At post-intervention no differences were found between the groups. At 3-month follow-up, anxiety showed a significant increase in the control group with no increase in the intervention group (d = 0.23; 95% CI: 0.05, 0.40); females in the control group had a significant decrease in well-being from post-intervention to 3 month follow-up compared to the intervention group (d = 0.33; 95% CI: 0.08, 0.58); students with high levels of perfectionistic concerns in the intervention had significantly lower perfectionistic strivings at 3 month follow-up than the control group ((d = 0.34, 95% CI: 0.19, 0.49). This intervention shows promising results when delivered by teachers. Australian New Zealand Clinical Trials Registry (ANZCTR) Trial Number: ACTRN12621000457842 (April 19, 2021).

This editorial seeks to encourage the increased application of three open science practices in eating disorders research: Preregistration, Registered Reports, and the sharing of materials, data, and code. For each of these practices, we introduce updated International Journal of Eating Disorders author and reviewer guidance. Updates include the introduction of open science badges; specific instructions about how to improve transparency; and the introduction of Registered Reports of systematic or meta-analytical reviews. The editorial also seeks to encourage the study of open science practices. Open science practices pose considerable time and other resource burdens. Therefore, research is needed to help determine the value of these added burdens and to identify efficient strategies for implementing open science practices.

Guided self-help is an evidence-based intervention used globally. Self-help is a fundamental part of the stepped care model of mental health services that enables the efficient use of limited resources. Despite its importance, there is little information defining the role of the guide and the key competences required. In this context, the guide is defined as the person who facilitates and supports the use self-help materials. This article sets out the role of the guide in guided self-help. It considers practical issues such as the importance of engagement to motivate clients for early change, personalising the intervention, structuring sessions, how best to use routine outcome monitoring and supervision requirements. Key competences are proposed, including generic competences to build the relationship as well as specific competences such as being able to clearly convey the role of the guide to clients. Guides should be prepared for "self-help drift", a concept akin to therapist drift in more traditional therapies. Knowing how to identify mental health problems, use supervision and manage risk and comorbidity are all key requirements for guides. The paper concludes by calling for increased recognition and value of the role of the guide within mental health services. [ABSTRACT FROM AUTHOR]

Objective Methods Results Conclusion This experimental study investigated the weight loss parameters and resulting end weight that influence clinician confidence in diagnosing atypical anorexia nervosa (AAN).Clinicians (N = 67) read a series of vignettes where patient weight loss and end weight varied, then rated their confidence in an AAN diagnosis and alternatives. Using repeated measures ANOVAs, we examined patient (weight loss, end weight) and the possible relationship between clinician (e.g., age, profession) characteristics and confidence in diagnosing AAN.Clinicians were most confident in an AAN diagnosis when patients had lost 10% or 15% of their body weight, leaving them at a high or normal weight. Clinicians considered 5% as significant weight loss for AAN, but only when the patient ended at a high or normal weight. However, they did not clearly differentiate AAN from unspecified feeding and eating disorder (UFED) when there was a 5% weight loss resulting in high or normal end weight. Clinician characteristics did not impact on confidence in diagnoses.The DSM's ‘significant weight loss’ criterion leaves room for clinicians to interpret it idiosyncratically. The lack of a clear pattern of UFED and AAN diagnosis has important clinical implications, as UFED tends to be dismissed as being less serious. [ABSTRACT FROM AUTHOR]

Objective: While co‐occurring mental health conditions are the norm in eating disorders, no testable protocol addresses management of these in psychotherapy. Method: The literature on managing mental health conditions that co‐occur with eating disorders is outlined and reviewed. Results: In the absence of clear evidence to inform managing co‐occurring mental health conditions, we advocate for use of an iterative, session‐by‐session measurement to guide practice and research. We identify three data‐driven treatment approaches (focus solely on the eating disorder; multiple sequential interventions either before or after the eating disorder is addressed; integrated interventions), and the indications for their use. Where a co‐occurring mental health condition/s impede effective treatment of the eating disorder, and an integrated intervention is required, we outline a four‐step protocol for three broad intervention approaches (alternate, modular, transdiagnostic). A research program is suggested to test the usefulness of the protocol. Discussion: Guidelines that provide a starting point to improving outcomes for people with eating disorders that can be evaluated/researched are offered in the current paper. These guidelines require further elaboration with reference to: (1) whether any difference in approach is required where the co‐occurring mental health condition is a comorbid symptom or condition; (2) the place of biological treatments within these guidelines; (3) precise guidelines for selecting among the three broad intervention approaches when adapting care for co‐occurring conditions; (4) optimal approaches to involving consumer input into identifying the most relevant co‐occurring conditions; (5) detailed specification on how to determine which adjuncts to add. Public significance: Most people with an eating disorder also have another diagnosis or an underlying trait (e.g., perfectionism). Currently no clear guidelines exist to guide treatment in this situation, which often results in a drift away from evidence‐based techniques. This paper outlines data‐driven strategies for treating eating disorders and the accompanying comorbid conditions and a research program that can test the usefulness of the different approaches suggested.

Less help-seeking for an eating disorder is predicted by higher levels of denial of, and failure to perceive, illness severity. This research evaluates a "backdoor" approach to early intervention by investigating whether internet cognitive behaviour therapy for perfectionism can significantly improve disordered eating. Additionally, we investigated whether a more interactive intervention impacted outcomes. Participants were recruited worldwide online; 368 were screened, 172 (46.7%) met inclusion criteria (endorsed high shape, weight, or eating concerns) and randomised to an interactive (Focused Minds Program; FMP) or static PDF intervention (Centre for Clinical Intervention; CCI-P) or waitlisted (control condition). Participants completed assessments on disordered eating, perfectionism, and a range of secondary variables at the end of treatment, and 1- and 3-month follow-up. Intent-to-treat analyses indicated that, compared to control, FMP resulted in significantly lower levels of disordered eating at each assessment and CCI-P at the 1- and 3-month follow-up (respective 3-month follow-up between group effect sizes of 0.78 and 0.54). There were no significant differences between the two active interventions on any measure except depression and hated self. Results suggest an alternative approach to directly tackling disordered eating that is low-cost is effective, with a more interactive intervention producing a more rapid effect.

Objective: Atypical anorexia nervosa (AN) is a serious eating disorder that is more common in the population than AN. Despite this, people with atypical AN are less likely to be referred or admitted for eating disorder treatment and there is evidence that they are less likely to complete or benefit from existing interventions. This study examined whether baseline readiness and/or confidence moderated outcomes from 10‐session cognitive behavioral therapy among people with atypical AN and bulimia nervosa (BN), and whether the impact of these variables differed between diagnoses. Methods: Participants (n = 67; 33 with atypical AN) were a subset from an outpatient treatment study. Linear mixed model analyses were conducted to examine whether baseline readiness and/or confidence moderated outcomes. Results: People with BN who had higher levels of readiness or confidence at baseline had steeper decreases in eating disorder psychopathology over time. There was no evidence that readiness or confidence moderated outcomes for people with atypical AN. Discussion: This study suggests that the moderators that have been identified for other eating disorders may not apply for people with atypical AN and highlights a need for future work to routinely investigate whether theoretically or empirically driven variables moderate outcomes in this little‐understood population. Public Significance Statement: People with bulimia nervosa with higher readiness and confidence experienced greater decreases in eating disorder symptoms than people with lower readiness and confidence when treated with cognitive behavioral therapy. These findings did not apply to people with atypical anorexia nervosa. Results demonstrate that future work is urgently required to identify helpful treatments for people with atypical anorexia nervosa as well as the variables that have a positive impact on outcomes in treatment for these individuals.

Suicide and self-harm have significant health, economic and social costs. Group-based interventions can be an effective and advantageous treatment approach; however, there is little evidence on the application of these groups in youth community mental health settings in Australia. Using the RE-AIM framework, we explore the feasibility and implementation of two group programmes in a youth-focussed community-based mental health service: dialectical behaviour therapy-adolescent (DBT-A) and cognitive behavioural Self and Strength (S&S). Data were collected from an Australian community mental health service that implemented two group therapy treatments over 12 months. RE-AIM implementation framework outcomes included programme reach (patient flow, group uptake, treatment completion), effectiveness (youth and care clinical outcomes), adoption (staff perception), implementation (barriers), and maintenance (service commitment and acceptability). Groups were considered for all eligible clients (61% of referrals), of these 36% accepted treatment and of those who commenced, 71% completed DBT-A and 82% completed S&S. DBT-A participants reported improved suicidality, emotion dysregulation, self-harm and quality of life (QoL). S&S participants reported improved QoL. Despite small sample size, treatment was acceptable to participants, with high retention and adherence across both groups. Clinicians involved in facilitation noted positive clinical impacts. Group-based interventions have the potential to reduce emotion dysregulation difficulties for youth. Understanding barriers to uptake of group programmes in community-based mental health settings is essential to improve the reach and implementation of group programmes. What is already known about this topic: Self-harm and suicide are major public health concerns for youth, with self-harm linked to suicide completion. High rates of self-harm and emotion dysregulation occur in youth presenting to community-based mental health services. Clinicians need to be able to offer evidence-based interventions to support these individuals. Group-based interventions for emotion dysregulation present an opportunity to improve health outcomes, facilitate skill development and encourage social help-seeking behaviour. What this topic adds: Group-based interventions for emotion dysregulation have positive clinical outcomes for young people who engage in these programmes and offer potentially cost-effective solutions to addressing youth mental health; however, reach was low. Staff facilitators and group participants reported high acceptability and provided positive feedback on the group programmes. Further investigation into the barriers for group therapy is required to develop and implement strategies to increase uptake of group therapy. [ABSTRACT FROM AUTHOR]

Evidence-based cognitive-behaviour therapy for eating disorders (CBT-ED) differs from other forms of CBT for psychological disorders, making existing generic CBT measures of therapist competence inadequate for evaluating CBT-ED. This study developed and piloted the reliability of a novel measure of therapist competence in this domain—the Cognitive Behaviour Therapy Scale for Eating Disorders (CBTS-ED). Initially, a team of CBT-ED experts developed a 26-item measure, with general (i.e. present in every session) and specific (context- or case-dependent) items. To determine statistical properties of the measure, nine CBT-ED experts and eight non-experts independently observed six role-played mock CBT-ED therapy sessions, rating the therapists' performance using the CBTS-ED. The inter-item consistency (Cronbach's alpha and McDonald's omega) and inter-rater reliability (ICC) were assessed, as appropriate to the clustering of the items. The CBTS-ED demonstrated good internal consistency and moderate/good inter-rater reliability for the general items, at least comparable to existing generic CBT scales in other domains. An updated version is proposed, where five of the 16 "specific" items are reallocated to the general group. These preliminary results suggest that the CBTS-ED can be used effectively across both expert and non-expert raters, though less experienced raters might benefit from additional training in its use.

Aim: Early intervention in eating disorders (EDs) is hampered by a lack of validated measures of barriers to treatment seeking. The present study examined the factor structure of the Perceived Barriers to Psychological Treatment scale (PBPT) and a combination of PBPT and Barriers to Seeking Help for ED items (BATSH‐ED) with respect to treatment‐seeking for an ED. Method: Participants were 456 female university students aged 17–25 reporting a wide range of disordered eating severity. Confirmatory factor analyses were conducted with the whole sample followed by correlational and regression analyses with a high‐risk sample to assess validity of the selected questionnaire items. Results: Four models were tested. First, we replicated the original PBPT 8‐factor structure in our sample with comparable fit indices. Second, the addition of six ED items comprising a Denial and Ambivalence subscale improved model fit. Third and fourth, when only significant subscales predicting treatment seeking were retained, with removal of items with weak loadings, a 15‐item six‐factor solution provided a best fit. A range of psychosocial measures had relationships in the expected directions with the questionnaire subscales. In addition to disordered eating, the denial subscale was uniquely associated with treatment seeking. Conclusions: While the present study contributes to refining the assessment of barriers to help‐seeking, future studies should consider co‐design with lived experience to further improve the model fit of the questionnaire and improve predictiveness of help‐seeking.
