Questionnaire Description

The Eating Disorder Diagnostic Interview (EDDI-31) is a diagnostic tool used for assessing eating disorders. It consists of 31 questions that cover various types of eating disorders, including anorexia, bulimia, and binge eating disorders. The EDDI-31 is designed to provide a systematic and structured approach for diagnosing and evaluating these disorders, thereby facilitating accurate diagnosis and appropriate treatment.

Analysis and Use of Data

Data analysis from the EDDI-31 is based on responses to the 31 questions. Each question focuses on specific symptoms or behaviors related to eating disorders. The analysis includes:
Score Compilation: Responses to each question are typically scored based on the severity of the symptoms. Scores are combined to provide an overall picture of the presence and severity of eating disorders.
Diagnosis: The assessment of total scores is used to diagnose specific eating disorders. The tool can identify characteristics consistent with anorexia, bulimia, or binge eating disorder.
Intervention Strategies: Based on diagnostic results, appropriate treatment strategies can be developed, such as cognitive-behavioral therapy or nutritional support.
Monitoring: The EDDI-31 can be used to monitor patient progress in treatment programs and evaluate the effectiveness of interventions.

Objective

Diagnosis: Identify eating disorders and differentiate between various types.
Severity: Assess the severity of symptoms and the need for treatment.
Treatment Strategies: Guide the development of appropriate treatment and intervention strategies.

Scoring

Scoring for the EDDI-31 includes:
Score Compilation: The total score is derived from the combined scores of the 31 questions.
Disorder Differentiation: Specific patterns and severity of symptoms are examined to confirm the diagnosis.
Severity Categories: Scores are categorized into levels such as mild, moderate, or severe to guide treatment approaches.
