Abstract

This study aimed to develop and examine the validity evidence of the New Somatomorphic Matrix-Male (NSM-M) as a measure of actual-ideal body discrepancy. The NSM-M is a visual matrix of 34 male bodies that vary along two dimensions: body fat percentage (range = 4-40%) and muscularity (fat-free mass index; range = 16.5-30 kg/m2; 36.4-66.1 lbs/m2). In Study 1, participants were 2,733 sexual minority males recruited via a geosocial networking smartphone application. Participants selected their actual and ideal bodies on the NSM-M and additionally completed questionnaires measuring body dissatisfaction, eating disorder symptoms, quality of life, and anabolic steroid use. In Study 2, participants were 33 males from a community sample. They completed the NSM-M across two sessions, 7-14 days apart. NSM-M scores demonstrated concurrent and convergent validity as a measure of male body dissatisfaction. In addition, NSM-M scores discriminated between steroid users and nonusers, and between body mass index categories. The NSM-M also demonstrated sound test-retest reliability across a 7- to 14-day period. In sum, the NSM-M is validated figural measure of male actual-ideal body discrepancy with notable strengths, including fast administration time and enhanced ecological validity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
