Psychometric validation of the FACE‐Q Aesthetics Satisfaction with Temples scale in individuals seeking minimally invasive treatment to improve temple hollowing

Abstract

AbstractBackgroundThe FACE‐Q Aesthetics is used extensively to measure patient reported outcomes for minimally invasive and surgical facial aesthetic treatments. We recently developed a new FACE‐Q scale to assess satisfaction with the appearance of the temples.AimThe aim of this study was to field test the FACE‐Q Satisfaction with Temples scale to examine its psychometric properties.MethodsThe FACE‐Q Satisfaction with Temples scale was administered to 171 adults (22 years or older) seeking minimally invasive treatment to improve temple hollowing as part of a clinical trial. The severity of temple hollowing was established through the clinician‐reported Allergan Temple Hollowing scale (clinician‐rated). The psychometric properties of the FACE‐Q Satisfaction with Temples scale were established by testing Rasch Measurement Theory (RMT) assumptions and model fit; unidimensionality by principal component analysis; and construct validity by hypothesis testing.ResultsThe study sample consisted of 171 adults (mean age 54.7 ± 9.9, range, 25–82 years). RMT analysis provided evidence for the scientific soundness of a 12‐item Satisfaction with Temples scale. The data fit the Rasch model (χ2 = 20.47, df = 24, p = 0.67), all items had ordered thresholds, and good item fit. Scale reliability was high, with Person Separation Index and Cronbach alpha values with and without extremes ≥0.93. Principal component analysis revealed a single component with high factor coefficients. Construct validity was established as scores for the Satisfaction with Temples and Face Overall scales were correlated (r = 0.623, p < 0.001).ConclusionThe FACE‐Q Satisfaction with Temples scale is a reliable and valid measure that can be used in clinical practice and research to measure outcomes following treatment for temple hollowing.
