Relapse Prevention for Binge Eating Disorder
By Julie Friedman, PhD, and Kara Richardson Whitel
With the advent of DSM-5, binge eating disorder (BED) was elevated to the status of full-fledged eating disorder diagnosis and a separate entity distinguishable from other feeding and eating
disorders versus a residual “eating disorder not otherwise specified.” DSM-5 also lowered the diagnostic threshold for BED by decreasing the frequency and duration of symptoms needed to meet diagnostic criteria. Research suggests that the impact of DSM-5 was to successfully reduce reliance on the residual “unspecified” category and provide further differentiation between types of eating disorder psychopathology (Nakai et al., 2017). In addition, the severity specifiers (mild-severe as determined by frequency of binge-eating episodes) seem to provide some clinical utility, with significant between-group differences observed in treatment outcome. As expected, patients with “mild” BED showed greater rates of abstinence from binge-eating episodes following treatment than patients with “severe” BED (Dakanalis et al., 2017).
With regard to treatment efficacy, cognitive behavioral therapy (CBT) (in both guided self-help and therapist-led forms) is the most well-established psychological treatment for BED (Wilson & Shafran, 2005), with studies showing the efficacy of CBT in generating both immediate reductions in behavior and long-term maintenance of treatment gains (Hilbert et al., 2012). The scope of adjunctive and combination therapies in concert with CBT is too large for this paper, but, interestingly, recent findings (Grilo, Reas, & Mitchell, 2016) show that pharmacotherapy plus CBT yields more effective treatment than pharmacotherapy alone, yet does not significantly change the impact of CBT alone. More research is needed to establish pharmacotherapy guidelines in the long term, owing to small sample sizes and other methodological concerns.
Through an interwoven recovered patient and provider perspective, the present writers would like to highlight the need for deepening the work of CBT for BED by highlighting cognitive and psychological variables that, if adequately addressed by CBT, could augment treatment outcomes and enhance CBT’s focus on relapse prevention—thus, creating more individualized, more effective, and more efficient treatment for patients. We suggest that the following variables (if present) be attended to, along with the traditional overconcern with weight and shape and dietary restraint focus of CBT:
- Impulsivity and Negative Urgency. Negative urgency is defined as the tendency to behave impulsively or engage in rash, ill-considered decision-making in response to a negative or intense affective state. A recent study (Manasse et al., 2016) showed that working on emotion-regulation skills is inadequate in producing decreases in the tendency to manifest impulsive behaviors secondary to negative affect. The authors concluded that an explicit focus on developing skills for delaying or withholding impulsive responses in the context of strong negative emotion is necessary for those patients with high negative urgency and impulsive responses to food cues when stressed. Skills such as noticing the urge to binge and responding to it nonemotionally and nonjudgmentally (thought defusion); “urge surfing” and “urge postponement,” in which patients are taught to delay responding to urges to binge in a series of sequential steps; and formal problem-solving skills would all effectively address negative urgency and can be easily incorporated into a CBT protocol.
As someone who learned to use food at age 9 after my parents’ divorce and then took a deep dive into binge eating disorder at age 12 after being sexually assaulted, I’ve spent my adult life trying to undo an eating disorder that consumed me. I’ve even climbed Mount Kilimanjaro three times in search of answers.
The most daunting and difficult parts of the recovery journey have been when I’ve relapsed, especially after that first climb, after the birth of my oldest daughter. Veering off-path is so shrouded in shame and embarrassment, but each tumble off-trail has helped me get back up stronger and faster.
As my coauthor has taught me, binge eating disorder is squarely based in neurobiology; thus, my treatment had to “rewire” my brain. In this life, where one must have food to survive, I had to learn how to adapt differently to the brain I have. I still have the same urges and vulnerabilities and I’ve had relapses, but the key is responding to them differently.
- Wang and colleagues (2017) published the first study looking specifically at the role of rumination in the persistence of eating disorder psychopathology in a sample of BED patients with comorbid obesity. Specifically, these researchers found that rumination—the focused attention on symptoms (causes and consequences) of one’s distress—predicted BED symptomatology above and beyond overconcern with shape and weight, and led to greater weight bias internalization. Specific interventions that decrease brooding and increase pleasurable and accomplishment-oriented activities through activity scheduling, behavioral activation, and exposure and response prevention (i.e., brooding and thought exposures) can be incorporated into CBT for BED protocols. It might reduce the role of overconcern of shape and weight if these skills can target and decrease weight bias internalization.
- Attention to Vulnerabilities: Acute and Chronic Stress and Sleep Deprivation. Lyu and Jackson (2016) showed (via fMRI) that following an acute unpleasant stressor, women with BED (vs. women without BED) showed preferences for high-calorie food images and reduced inhibitory activation in areas of the hippocampus, and displayed more consumption of highly palatable foods post-stressor while deriving less satisfaction and pleasure from the food. While a larger and more varied sample is needed to further generalize these results, a substantial body of literature shows a (largely correlational) relationship between adverse experiences and eating disorder symptomatology (Trottier & MacDonald, 2017). Therapeutic attention to skills that increase adaptive coping (and coping without the use of eating-disordered behaviors) with both acute and chronic stressors (i.e., weight bias, food scarcity, emotional neglect or abuse, traumatic experiences) might be a useful adjunct to traditional CBT protocols. Stress inoculation training, prolonged exposure and exposure and response prevention, and distress tolerance skills might supplement traditional enhanced CBT (CBT-E) protocols and assist in relapse prevention. Similarly, sleep deprivation has been shown to increase appetite, decrease satiety, and increase consumption of both overall calories and highly palatable foods (Spiegel et al., 2004). CBT for insomnia, including stimulus control, sleep hygiene, and, potentially, sleep restriction, might be a useful adjunct to CBT for BED and particularly useful in relapse prevention. More research is needed—especially in the area of sleep deprivation among patients with eating disorders in general and BED specifically.
When I was a new mom, I was too deep in the trenches of insomnia, depression, and fear of failure to ask for help. I spent time milling through my cabinets looking for my next binge, instead of learning how to deal with what was going on. So much of relapse prevention is learning to do something differently. Now, when I’m sleep-deprived, I acknowledge it. Instead of pushing it away, I go easy on myself, maybe even take a nap. If I’m stressed, I make a list to organize my thoughts and create a plan to deal with the problem. I ask for help from my family, from my therapist, from anyone who will help me keep on track. I serve as a binge eating disorder recovery advocate to inspire others to do the same.
In conclusion, while a substantial body of research shows that CBT is an effective treatment for BED, a more comprehensive understanding of how we can both deepen and expand upon current protocols is essential for abstinence or decreased symptoms of BED in the long term.
