Psychological Explanations for Anorexia Nervosa: Family Systems Theory
According to the theory, the adolescent feels a 'paralyzing sense of ineffectiveness' due to the overbearing family structure. They perceive themselves as having no control over their own life or choices.
Anorexia as Protest: The refusal to eat is interpreted as a desperate attempt to assert autonomy. By controlling their body weight, the adolescent finds one area of life where the parents cannot easily intervene.
Visible Control: Weight loss serves as a tangible, visible measure of the individual's success in self-management. It is a way of saying 'I am separate from you' in a system that tries to keep everyone the same.
| Feature | Family Systems Theory | Biological Explanations |
|---|---|---|
| Primary Cause | Dysfunctional interpersonal dynamics | Genetic or neural abnormalities |
| View of the Patient | A symptom-bearer for the family | An individual with a physiological disorder |
| Function of AN | A tool for gaining autonomy/control | A result of chemical or genetic imbalance |
| Treatment Focus | Restructuring family boundaries | Nutritional and pharmacological intervention |
Focus on the 'Why': When discussing this theory, do not just list the symptoms of AN. Instead, explain how the symptoms solve a problem for the family system (e.g., how it avoids conflict).
Use the Four Traits: Ensure you can define and apply Enmeshment, Overprotectiveness, Rigidity, and Conflict Avoidance. These are the 'bread and butter' of exam marks for this topic.
Evaluate the Evidence: Be prepared to discuss the limitations of the research, such as the fact that much of it relies on self-report data which can be biased by social desirability.
Causality vs. Correlation: Always consider if the family dysfunction caused the AN, or if the stress of having a child with AN caused the family to become enmeshed and overprotective.
Parent-Blaming: A common mistake is to view this theory as 'blaming' parents. Modern interpretations emphasize that the system is dysfunctional, and parents are often acting out of a misplaced sense of love or anxiety rather than malice.
Enmeshment vs. Closeness: Students often confuse being a 'close' family with being an 'enmeshed' one. Closeness allows for individual growth; enmeshment actively prevents it.
Gender Bias: The theory is often criticized for focusing almost exclusively on mother-daughter relationships, which may ignore the experiences of males with AN.
