Validating the Persian Intuitive Eating Scale-2 Among Breast Cancer Survivors Who Are Overweight/Obese

Area of Science:

• Oncology
• Psychology
• Nutrition Science

Background:

• Overweight/obesity in breast cancer patients increases mortality risk.
• Intuitive eating may offer benefits for weight management in this demographic.
• Validating assessment tools is crucial for research and clinical practice.

Purpose of the Study:

• To validate the Persian version of the Intuitive Eating Scale-2 (IES-2).
• To assess the psychometric properties of the IES-2 in overweight/obese Iranian women with breast cancer.
• To examine the scale's concurrent validity with other psychological and health measures.

Main Methods:

• Confirmatory factor analysis (CFA) and Rasch analysis were used for psychometric evaluation.
• A cohort of 762 overweight/obese Iranian women with breast cancer completed the IES-2 and other validated scales.
• Statistical analyses assessed the scale's factor structure, reliability, and validity.

Main Results:

• The Persian IES-2 demonstrated robust psychometric properties and a confirmed four-factor structure.
• The scale showed concurrent validity through significant correlations with measures of self-efficacy, mental health, body appreciation, weight bias, and eating attitudes.
• All items were found to be meaningful within their respective domains.

Conclusions:

• The Persian IES-2 is a well-validated and applicable instrument for assessing intuitive eating.
• This tool can be utilized in research and clinical settings for overweight/obese breast cancer survivors.
• Findings support the use of the IES-2 to understand eating behaviors in this specific population.
