Factor Structure of the Polish Version of Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-PL).

In Poland, there is no tool for measuring the variable body image that would have standardization or Polish norms adjusted to the population of both women and men. The available Multidimensional Body-Self Relations Questionnaire (MBRSQ) validation developed in Poland was based on a small population of young women only. The aim of this article is to present Polish adaptation and standardization for polish adult women and men (MBSRQ-AS). In the study, the psychometric properties and factor structure of the Polish version of MBSRQ-AS were tested. The participants were 2688 people, including 1699 young women and 1089 young men. In order to investigate the psychometric properties of the adapted Polish tool, an exploratory factor analysis (EFA) was performed. Then, the reliability coefficients were calculated, and the descriptive statistics of individual subscales were checked. The separated subscales are characterized by high indexes of factor loadings, ranging most often from 0.47 to 0.78. Separate subscales of the MBRSQ-PL questionnaire were defined: (1) self-esteem of the body and its parts, (2) self-assessment of physical, (3) self-assessment of external appearance, (4) Negation of one's own physical activity, (5) Self-assessment of health condition, (6) health anxiety, (7) fear of gaining weight, (8) neglecting health and appearance.
