Treatment Quicker and Better: What is the Evidence for Short-Term Treatments in Eating Disorders?

There is a growing body of research to show that short-term treatments may achieve similar therapeutic outcomes to longer term interventions (e.g., Ost & Ollendick, 2017; Waller et al., 2018). This reflects, in part, a non-linear dose-response relationship between treatment duration and treatment outcomes, with benefits dropping off rapidly after an initial optimum ‘dose’. In addition, early symptom change is one of the most potent predictors of longer-term outcomes in cognitive behavioral therapy and family-based therapy, and if early reductions in symptoms do not occur, additional treatment may offer relatively little benefit (Le Grange et al., 2014; Rose & Waller, 2017; Turner et al., 2015). This plenary seeks to examine evidence around the optimum dose-response relationship in the treatment of psychological disorders generally and eating disorders more specifically. In addition, it aims to describe and evaluate some of the available short-term interventions for eating disorders.
Learning Objectives:
- To explore the relationship between treatment duration and treatment outcomes in eating disorders.
- To explore the evidence base for short-term interventions for eating disorders.
Balancing Input with Output: How Treatment Duration Relates to Symptom Improvement
Michael Barkham, BEd, MA, MSc, PhD
University of Sheffield, Sheffield, UK
This presentation introduces and summarises various models and key issues in relation to treatment duration and symptom improvement within the broader field of research in the psychological therapies. Evidence on the relationship between treatment duration and outcome is drawn from randomised controlled trials and large practice-based (i.e., naturalistic) studies, including the UK government’s Improving Access to Psychological Therapies (IAPT) initiative. The clinical merits and challenges of shorter treatment durations are considered along with a number of caveats in relation to carrying out research in this area.
Doing Less to Achieve More: The Case of CBT-T for Eating Disorders
Glenn Waller, BA, MClinPsychol, DPhil
University of Sheffield, Sheffield, UK
While we routinely assume that ‘more therapy = better outcomes’ in working with eating disorders, the evidence for that assumption is poor. Indeed, offering more treatment can have negative outcomes for all concerned. This presentation will explain the development of a brief, ten-session therapy for non-underweight eating disorders (CBT-T) and will present evidence that doing less can indeed be better than doing more. Therapy can be cheaper, faster, and easier to access, without losing any effectiveness, and with very positive acceptability to the patients who undertake it. However, while patients are positive about shorter therapies, clinicians are often more resistant, and we need to understand why that is the case. Otherwise, we will continue to waste time when we could be helping more people to recover and reducing waiting times substantially.
Brief Single and Multifamily Interventions for Child, Adolescent and Young Adult Anorexia Nervosa: When, Why and in What Context
Ivan Eisler, OBE, PhD, FAED
Kings College, London, UK
Most treatment research in eating disorders tends to focus on trying to identify the best evidence-based treatments i.e. it centres on questions such as is treatment A better than treatment B or is one variant of treatment A better than another variant of treatment A. This presentation will take a broader look, that will include factors (individual, family as well as the service context) that may need to be included when considering using brief family treatments and the different aims that such brief treatments might have. For instance, recent major investment by the National Health Service in England to establish a network of specialist community-based services for young people with an eating disorder has resulted in a growing number of very early referrals at a point in time when the family is concerned but as yet has not been much affected by the emerging eating disorder and where a very brief intervention of 2-4 sessions may be all that is needed. A very different type of brief family intervention is a 5-day intensive multi-family therapy for young adults that we are currently developing at UCSD. The aim of this intensive intervention is primarily to address motivation to change and the ambivalence of the young person about accepting help and support from their families. For some, the brief intervention may itself lead to significant symptom change but for others the key aim is to target possible individual or family “roadblocks” and thereby facilitate other, longer individual or family treatments. The talk, while drawing on existing (though very limited) empirical evidence, will be more clinically oriented and will aim to raise new questions rather than provide answers.
Discussant
Tracey Wade, BSc, MClinPsych, PhD
Flinders University of South Australia, Adelaide, SA, Australia
The goal of this presentation is to summarize and synthesize key points from other presentations. The discussant will express their viewpoints on the optimal ‘dose’ of eating disorder treatment and short-term interventions in the field, drawing on the previous presentations, their own work, and the general literature on these issues. The Discussant will talk about her opinion regarding the optimal dose of treatment, based on a synthesis of information presented by speakers.
