A Short Guide to Everything You Need to Know About Eating Disorders

nedawareness_week_2019-shareables1

In honor of National Eating Disorders Awareness Week, I will attempt to create a post that links to everything you need to know about eating disorders.*, **

*Or at least gets you within a couple of clicks of a lot of things that are good to know.

**Scientists and clinicians don’t actually know everything we need to know about eating disorders yet, but I’ll share what we do.

Definitions

The Diagnostic and Statistical Manual of Mental Disorders includes formal definitions of eating disorders, such as anorexia nervosa, bulimia nervosa, binge eating disorder, and others. Even if someone does not meet full diagnostic criteria for an eating disorder, they may still struggle with eating disorder symptoms such as body dissatisfaction, loss-of-control overeating or undereating, preoccupation with food, weight, or shape, or unhealthy weight loss behaviors (e.g., abusing laxatives, self-induced vomiting, compulsive exercise). If you’re curious about your own eating behavior, you can take an online screening here.

Causes

There are a variety of different factors that increase the risk for eating disorder symptoms. You can read about them here or see the biopsychosocial model below for some of the main factors associated with eating disorders.

Treatments

Current research-supported eating disorder treatments include: family-based or Maudsley treatment, cognitive-behavioral therapy, integrative cognitive-affective therapy, and interpersonal psychotherapy.

There are also some scientifically-informed self-help books available:

How Psychologists Capture the Complexities of Mental Illness

When it comes to understanding and treating mental illness, clinical psychologists must strike a balance between grouping people with shared characteristics together and recognizing people’s individual paths, circumstances, and needs. Below I’ve described some of the models that clinical psychologists use to reflect these complexities.

1) Biopsychosocial Model

Most modern psychologists understand that mental illness is the result of both nature and nurture. Accordingly, biopsychosocial models map out biological, psychological, and social risk factors for mental health outcomes and highlight potential intervention points. This model is so prominent that clinical psychology graduate programs require education in human development, individual differences, and biological, cognitive, affective, and social aspects of behavior, and you can’t become a licensed psychologist without passing a formal test on these topics. The idea is that mental health outcomes result from the interplay of biological, psychological, and sociocultural factors and that different people arrive at outcomes through different combinations of factors. Here’s a sample I constructed from some suicide risk factors:

2) Diathesis-Stress Model

People with identical genetics (i.e., monozygotic twins) and people with shared stressful events (e.g., witnessing the same violent act) can have different mental health outcomes. For example, many people with family histories of eating disorders will not develop eating disorders. Likewise, many people who have been bullied about their weight will not develop eating disorders. A diathesis-stress model of eating disorders explains this by saying that a person must have both a vulnerability (e.g., a genetic predisposition) and a significant stressor (e.g., weight-related bullying) to develop an eating disorder.

3) Multifinality and Equifinality

People who experience a similar event (e.g., trauma) can have disparate outcomes that depend on other factors (e.g., financial resources, societal views of survivors). This is called multifinality. Meanwhile, people with similar outcomes (e.g., posttraumatic stress disorder) can arrive there via distinct pathways (e.g., surviving sexual assault, a car accident, being the victim of gun violence). This is captured with the term equifinality.

4) Distal vs. Proximal Factors

Most research on mental illness focuses on a few risk factors per study. Organizing findings across studies can feel like fitting puzzle pieces together to create a holistic picture. One way to do this is by grouping risk factors in terms of how far in time (distal) and how close in time (proximal) they are to the onset of mental illness. For example, strategies for reducing distal risk factors for adult depression may include public policy efforts to prevent childhood maltreatmentincrease access to quality health care, and decrease discrimination. Meanwhile, therapy for individuals with depression may focus on more proximal factors (e.g., enhancing coping skills, increasing social support, behavioral activation).

5) Nomothetic vs. Idiographic

I highly recommend this article by Beltz, Wright, Sprague, and Molenaar (2016) for detailed definitions of these terms:nom idioFor example, imagine that a client gets diagnosed with obsessive-compulsive disorder (OCD). In order to figure out the best way to help, a therapist begins with nomothetic information (e.g., the diagnosis) to select a treatment. A randomized clinical trial suggests that a type of cognitive-behavioral therapy called exposure and response prevention (EX/RP) leads to significant improvement among 80% of people with OCD after 17 sessions. Based on available information, EX/RP is a good place to start. However, it’s possible that the client will be among the 20% of people who don’t respond to EX/RP. Therefore, therapists must also pay attention to idiographic information after initiating treatment (e.g., by regularly assessing the client’s OCD symptoms over time). If the client’s not responding to therapy, the idiographic data signal that the therapist must figure out why and make appropriate changes.

I’ve described frameworks that clinical psychologists use to understand people’s mental health needs at multiple levels while respecting their individuality. The dedicated people working hard to alleviate suffering in the face of these challenges give me hope for the future of the field.

10 Star Wars Quotes for Therapists
