Abstract

Abstract: The objective of this study was to re-examine the factor structure of the Body Image Quality of Life Inventory (BIQLI), a measure that quantifies perceived effects of one's body image on various aspects of psychosocial functioning. Data on the 19-item BIQLI from a community sample of 11, 620 U.S. men and women were split into cross-validation samples and underwent exploratory and confirmatory factor analysis. An abbreviated 10-item, two-factor version of the BIQLI (BIQLI-10) was identified. The BIQLI-10 measures Social Relations & Psychological Well-Being with one subscale and Appearance & Body Management Activities with the other. Internal consistency was high for each subscale. The BIQLI-10 largely retained the convergent validity of the original 19-item BIQLI, as evidenced by nearly identical correlations with appearance evaluation, overweight preoccupation, body surveillance, appearance pressures, and appearance ideal internalization. Results also supported strong measurement invariance for the BIQLI-10 by age group, gender, sexual orientation, racial group, and weight status. Findings from this study suggest researchers may use this abbreviated version to increase nuance in the measurement of body image quality of life and reduce participant burden without compromising the psychometric integrity of the BIQLI. Further, results support the comparison of BIQLI-10 subscale scores across diverse groups. Highlights: An abbreviated 10-item, two-factor version of the BIQLI (BIQLI-10) was identified. One subscale measures Social Relations & Psychological Well-Being. The other subscale measures Appearance & Body Management Activities. The BIQLI-10 is internally consistent and invariant across various groups. The BIQLI-10 retained the convergent validity of the original BIQLI.
