Abstract
Objective: Although the Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ) and Ideal Body Stereotype Scale (IBSS) are used interchangeably to assess thin ideal internalization, limited work has examined the assumption that the two measures index the same construct.
Method: The current study utilized confirmatory factor analysis to examine whether these measures capture a single construct (one‐factor), two constructs (two‐factor), or both shared and unique constructs (bifactor). The SATAQ‐4R‐Internalization: Thin/Low Body Fat subscale and IBSS‐Revised were administered to 1,114 college females.
Results: A bifactor model provided the best fit to the data. Further, the SATAQ‐4R was more strongly related to disordered eating and body satisfaction than the IBSS‐R.
Discussion: Results indicate that the two most commonly used measures of internalization capture both shared and unique constructs. While both measures appear to contribute to the assessment of a global internalization factor, the SATAQ‐4R may be better suited to assess personal acceptance of and desire to achieve a thin body, while the IBSS‐R may be better suited to assess an awareness or acknowledgement of broader sociocultural ideals (e.g., toned, shapely bodies). Continued psychometric investigation of the scales is recommended in order to ensure targeted assessment of the intended constructs.
