Development and psychometric evaluation of the breast size satisfaction scale

The purpose of this paper is to develop and evaluate psychometrically an instrument named the Breast Size Satisfaction Scale (BSSS) to assess breast size satisfaction.

The present scale was developed using a set of 16 computer-generated 3D images of breasts to overcome some of the limitations of existing instruments. The images were presented to participants and they were asked to select the figure that most accurately depicted their actual breast size and the figure that most closely represented their ideal breast size. Breast size satisfaction was computed by subtracting the absolute value of the difference between ideal and actual perceived size from 16, such that higher values indicate greater breast size satisfaction.

Study 1 (n=65 female undergraduate students) showed good test-retest reliability and study 2 (n=1,000 Iranian women, aged 18 years and above) provided support for convergent validity using a nomological network approach.

The BSSS demonstrated good psychometric properties and thus can be used in future studies to assess breast size satisfaction among women.
