Bulimia Nervosa: Diagnosis and Treatment Planning

Abstract

This paper will evaluate contemporary approaches used to assess and diagnose Bulimia Nervosa.

Rationale for the diagnosis will be presented, as well as the advantages and limitations of using

the DSM for diagnosis. I will apply the 5-axis diagnostic system of the DSM-IV-TR to a client of record

who presented with Bulimia Nervosa. I will present a treatment plan based upon best-practice research

regarding treating of Bulimia. Additionally, I will evaluate the social systems of the client and assess what

impact these will have upon treatment planning for the client. Lastly, I will discuss how managed care

health insurance might influence the treatment process.

 Prevalence of Eating Disorders           
     
    The DSM-5 shows the following prevalence rates for Bulimia Nervosa (BN): The lifetime prevalence
was 0.8% for AN, 2.6% for BN, 3.0% for BED, 2.8% for atypical AN, 4.4% for sub threshold BN, 3.6% for sub threshold BED, and 3.4% for PD based on the newly proposed diagnostic criteria. The overall lifetime prevalence of any eating disorder by age 20 was 13.1%” (Stice, Marti, & Rohde, 2013). Additionally, Newman et al. (1996) state, “Eating disorders (ED) show stronger relations to suicide attempts, outpatient and inpatient treatment, and functional impairment than virtually all other psychiatric disorders.” Stice, Marti, & Rohde (2013) confirm this: “Participants with DSM-5 BN, BED, and sub threshold BN reported significantly greater functional impairment, emotional distress, suicidality, and elevated treatment seeking than participants without an eating disorder.” Since 1987, hospitalizations for ED in Canada have increased by 34% among adolescents females under the age of 15 (Public Health Agency of Canada, 2002) making it likely that clinicians may encounter these complex and potentially lethal illnesses more frequently. “ED pose particular treatment challenges and it is important to intervene early in the illness development to prevent more chronic and treatment-resistant forms of AN and BN from developing” (leGrange & Loeb, 2007).

Contemporary Approaches to Assessment and Diagnosis of Eating Disorders 
  
     Tobin et al. (1991) state, “Despite attempts in the DSM-III-R to improve diagnosis of bulimia nervosa
over criteria in the DSM-III (American Psychiatric Association, 1980), there remains considerable

subjectivity in diagnosis of this disorder.” In light of the subjective nature of using the DSM to diagnose,

the “Interview for Diagnosis of Eating Disorders, IDED-IV” (Kutlesic et al.,1998) can aid clinicians in

more accurate assessment. Several studies have found that the EDE yields reliable and valid data when

used to assess the symptoms of anorexia and bulimia (Fairburn & Cooper, 1993).


Advantages and Limitations of DSM Diagnosis
   
   
 Using a combination of the DSM for client self-report of symptoms combined with a formal assessment

instrument seems to be best-practice delivery of mental health services. Using the DSM to

exclusively diagnose is advantageous to the clinician in that it allows the clinician flexibility in structuring

questions based upon client self-report. However, it limits the accuracy of diagnosis, as leGrange, &

Loeb (2007) discovered: “More than 90% of the total sample (of general psychologists and ED

psychologists) indicated that they encountered child or adolescent patients who presented with ED who

they were unable to treat.” Both groups of clinicians rated themselves as low on ability to treat ED, siting

lack of skills, case complexity, and lack of resources as being problematic. This leads to the conclusion

that “formal training opportunities in the area of pediatric ED during medical school and doctoral studies”

should be increased (leGrange & Loeb, 2007).

Rationale for Diagnosis
    
    According to the DSM-lV-TR (2000) diagnostic criteria for BN is:
A. Binge Eating
B. Recurrent compensatory behavior (such as: vomiting, fasting, excessive exercise, laxatives, enemas or diet medications)
C. Binge Eating and Compensatory behaviors both occur at least twice a week for 3 months
D. Self-evaluation is unduly influenced by weight
E. Disturbance does not occur during episodes of Anorexia Nervosa.
The case study I presented of the “Case of the Bulimic Model” meets all criteria established by the DSM for BN.

Applying the 5-axis Diagnostic System
    
    The Bulimic client is a 23 year old female model named Stephanie who reports having suffered with Bulimia since the age of 19. The triggering event was her ex-boyfriend’s comment that he broke off the relationship because she had “gained a few pounds.” Stephanie suffers from low self-esteem and body dysmorphia. In applying the DSM 5-axis diagnostic system, I would assign the following:
l)      Clinical Syndromes/Disorders-Bulimia Nervosa is classed by the DSM as a mental disorder. Body Dysmorphia is also a mental disorder.
 II) Personality Disorders/Mental Retardation-Client has no symptoms of personality disorder nor deficiencies in intelligence.
lll) Medical Conditions-Client reports no present medical conditions, though in the past experienced amenorrhea due to restricting and purging.
lV) Psychosocial and Environmental Stressors-Client is a professional model. Her only social contacts are other models who also admit to having eating disorders. Client’s family and boyfriend live out of state, and she is no longer attending church where she used to find spiritual support. Client reports having made no friends outside of models at her agency. She is having financial difficulties due to lack of work.
V) Global Assessment of Functioning (GAF)-Client has poor insight regarding her choice of modeling career which maintains BN. She is socially isolated and her family does not know about her eating disorder. Client has medium-level depression and experiences high anxiety due to body dysmorphia. While client presents in counseling well-groomed, she is frequently tearful and makes self-deprecating remarks.

GAF Score of: 43, due to: Serious impairment in relationship with friends (no current friends), serious impairment in thinking (distorted body image and preoccupation with weight), and serious impairment due to anxiety (overwhelming anxiety).

Treatment Plan for Bulimia Nervosa
   
Evidence-based treatment approaches for BN indicate Cognitive-Behavioral Therapy as the standard

psychotherapeutic approach for eating disorders. However, a new model of therapy known as Integrative

Cognitive-Affective Therapy for the treatment of bulimia nervosa is an emotion-focused treatment that

emphasizes emotion regulation skills in clients with BN (Basada, 2011). Combining elements

from Dialectical Behavioral Therapy (DBT) and Cognitive-Behavioral Therapy, Integrative Cognitive-

Affective Therapy offers the emotional-regulation skills of DBT in addition to the empirically-proven CBT

Model which emphasizes cognition and resulting behaviors.

 Social Systems and Diagnosis

   In a large study of multifactorial assessment of bulimia nervosa, Tobin et al. (1991) concluded, “Factors

that promote depression and affective instability, whether biologic, systemic, or psychological, represent

another complicating dimension of bulimic symptoms.” It is clear that the systemic or environmental

influences upon the client will impact treatment outcome and must be accounted for. The client’s only

social influences are the modeling agency and the models she refers to as “friends.” She has hidden her

BN since the age of 19 and may have moved out of state from her family to keep her disorder a secret.

Because the modeling agency encourages anorexic-like body types, and because her modeling friends

have admitted having the same problem as the client, treatment planning for her becomes challenging, as

this is her only means of income; to change jobs would mean a loss of all income. These factors must be

topics for discussion with the client when considering treatment planning.  


Managed Care Health Insurance and Treatment
  
  In order for the client to enter an in-patient treatment facility, authorization (approval) must be obtained prior to admittance. This process can take time and certain criteria must be met. Clients who are needing hospitalization for eating disorders should find out what their insurance covers and how long the process takes should hospitalization become necessary. Often, clients whose disorders are not critical prefer a course of psychotherapy to in-patient care. Because ED are complex and a specialization within mental health, families should not delay in seeking a second opinion if they believe the healthcare professional is not treating the eating disorder seriously as the life-threatening situation it is.
