Anorexia Nervosa Ap Psychology Definition

Anorexia Nervosa: An AP Psychology Deep Dive

Anorexia nervosa, a potentially life-threatening eating disorder, is characterized by a relentless pursuit of thinness and an intense fear of gaining weight. This article provides a comprehensive overview of anorexia nervosa from an AP Psychology perspective, covering its diagnostic criteria, etiology, symptoms, treatment approaches, and the crucial interplay of biological, psychological, and sociocultural factors. Understanding this complex disorder requires exploring its multifaceted nature and the devastating impact it has on individuals and families.

Introduction: Defining Anorexia Nervosa

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) defines anorexia nervosa as an eating disorder characterized by two core features: significantly low body weight and an intense fear of gaining weight or becoming fat, even when underweight. This fear is often disproportionate to one's actual body weight and shape. Individuals with anorexia often exhibit a distorted body image, perceiving themselves as overweight even when emaciated. The relentless pursuit of thinness significantly impacts their lives, leading to serious physical and psychological consequences. It is important to differentiate anorexia nervosa from other eating disorders, like bulimia nervosa and binge-eating disorder, which have distinct diagnostic criteria. Understanding these distinctions is crucial for accurate diagnosis and effective treatment.

Diagnostic Criteria According to the DSM-5

The DSM-5 outlines specific criteria for diagnosing anorexia nervosa. These criteria help mental health professionals differentiate anorexia from other conditions and ensure appropriate treatment planning. The key criteria include:

• Restriction of energy intake relative to requirements, leading to significantly low body weight in the context of age, sex, developmental trajectory, and physical health. This is often measured using body mass index (BMI), which is calculated using height and weight. However, BMI isn't always a perfect indicator, as muscle mass can influence the result.

• Intense fear of gaining weight or becoming fat, or persistent behavior that interferes with weight gain, even though significantly underweight. This fear is often pervasive and overrides other aspects of the individual's life.

• Disturbance in the way in which one's body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or persistent lack of recognition of the seriousness of the current low body weight. This points to the significant cognitive distortion associated with the disorder.

The DSM-5 further subdivides anorexia nervosa into two subtypes:

• Restricting type: During the current episode of anorexia nervosa, the individual has not regularly engaged in binge-eating or purging behavior (i.e., self-induced vomiting or the misuse of laxatives, diuretics, or enemas). Weight loss is primarily achieved through dieting, fasting, or excessive exercise.

• Binge-eating/purging type: During the current episode of anorexia nervosa, the individual has regularly engaged in binge-eating or purging behavior. This subtype reflects a more complex presentation, often involving a cycle of restrictive eating followed by periods of uncontrolled eating and compensatory behaviors.

Etiology of Anorexia Nervosa: A Multifaceted Perspective

The etiology of anorexia nervosa is complex and not fully understood. A biopsychosocial model, which considers biological, psychological, and sociocultural factors, provides the most comprehensive explanation.

1. Biological Factors:

• Genetic predisposition: Family and twin studies suggest a genetic component to anorexia nervosa. Specific genes haven't been identified, but research indicates a heritable vulnerability to the disorder. This vulnerability might manifest as a predisposition to certain personality traits or a heightened sensitivity to environmental stressors.

• Neurobiological factors: Neurotransmitter imbalances, particularly in serotonin and dopamine systems, may play a role. These neurotransmitters are involved in mood regulation, appetite control, and reward processing. Dysregulation in these systems could contribute to the distorted body image, obsessive thoughts about food and weight, and the intense drive for thinness.

2. Psychological Factors:

• Personality traits: Individuals with anorexia often exhibit certain personality traits, including perfectionism, obsessive-compulsiveness, and a need for control. These traits may predispose them to restrictive eating patterns and a preoccupation with body image. The pursuit of thinness can become a way to exert control in other areas of life where they feel powerless.

• Cognitive distortions: Individuals with anorexia often hold distorted beliefs about their body, food, and weight. They may severely underestimate their body size and overestimate their weight. These cognitive biases reinforce restrictive eating behaviors and make it difficult to recognize the severity of their illness.

• Underlying emotional issues: Anorexia nervosa can be a way of coping with underlying emotional distress, such as anxiety, depression, trauma, or low self-esteem. Restricting food can provide a temporary sense of control and mastery in the face of overwhelming emotions.

3. Sociocultural Factors:

• Media influence: The media's portrayal of thinness as ideal contributes to body image dissatisfaction and the pressure to conform to unrealistic beauty standards. This cultural pressure, particularly among young women, can be a significant factor in the development of anorexia nervosa.

• Cultural values: Societal emphasis on thinness and the pursuit of an ideal body shape can create a climate where individuals feel pressured to conform. This pressure can be particularly intense in certain cultural groups or settings.

• Family dynamics: Family environment and relationships can play a role in the development and maintenance of anorexia nervosa. Issues such as enmeshment, control, conflict, and dysfunction in family systems can create a context where anorexia may emerge as a coping mechanism.

Symptoms of Anorexia Nervosa: Recognizing the Warning Signs

Anorexia nervosa manifests in a range of symptoms, both physical and psychological. Early recognition of these symptoms is crucial for timely intervention.

Physical Symptoms:

• Significant weight loss: A noticeable decrease in body weight, often resulting in a BMI significantly below the healthy range.

• Amenorrhea: Absence of menstruation in females.

• Lanugo: Fine, downy hair that grows on the body as a response to malnutrition.

• Dry skin and brittle hair and nails: Signs of nutritional deficiencies.

• Low blood pressure and slow heart rate: Cardiovascular complications due to malnutrition.

• Electrolyte imbalances: Life-threatening imbalances in essential minerals such as sodium and potassium.

• Osteoporosis: Weakened bones due to nutritional deficiencies and hormonal imbalances.

Psychological Symptoms:

• Distorted body image: A persistent belief that one is overweight, even when severely underweight.

• Intense fear of gaining weight: A pervasive fear that overrides other aspects of life.

• Preoccupation with food and weight: Excessive focus on food, calories, and weight.

• Restrictive eating behaviors: Strict dieting, fasting, or excessive exercise.

• Binge-eating and purging behaviors (in some cases): Episodes of uncontrolled eating followed by self-induced vomiting, laxative abuse, or other compensatory behaviors.

• Depression and anxiety: Common co-occurring conditions.

• Social isolation: Withdrawal from social activities and relationships.

Treatment Approaches: A Multidisciplinary Effort

Treatment for anorexia nervosa is complex and usually requires a multidisciplinary approach involving medical professionals, therapists, and dieticians. The goals of treatment are to restore weight, address the psychological issues underlying the disorder, and prevent relapse.

1. Medical Management:

• Hospitalization: In severe cases, hospitalization may be necessary to stabilize the individual's physical condition and address immediate health threats. This involves monitoring vital signs, restoring electrolyte balance, and providing nutritional support.

• Nutritional rehabilitation: A registered dietitian works with the individual to develop a meal plan that gradually increases caloric intake while addressing nutritional deficiencies.

• Medication: Medications may be used to treat co-occurring conditions such as depression, anxiety, or obsessive-compulsive disorder. However, there isn't a specific medication for anorexia nervosa itself.

2. Psychological Therapies:

• Cognitive behavioral therapy (CBT): CBT helps individuals identify and change maladaptive thoughts, feelings, and behaviors related to food and body image. It focuses on challenging distorted beliefs and developing more adaptive coping strategies.

• Family-based therapy (FBT): FBT, particularly effective for adolescents, involves the family in the treatment process. It focuses on restoring healthy eating patterns and improving family dynamics.

• Dialectical behavior therapy (DBT): DBT helps individuals develop skills to manage intense emotions, improve interpersonal relationships, and tolerate distress without resorting to self-harm behaviors.

3. Long-Term Management and Relapse Prevention:

Recovery from anorexia nervosa is a long-term process that requires ongoing support and vigilance. Relapse prevention strategies, such as regular therapy sessions, continued nutritional monitoring, and the development of coping mechanisms for managing stress and emotions, are essential for maintaining recovery.
