Should We Use a Total Score, Two Subscale Scores, or Six Subscale Scores for the Self-Compassion Scale? A Multi-faceted Assessment Beyond Model Fit Indices

Abstract Objectives The aim of this study was to conduct a multi-faceted assessment the psychometric properties Self-Compassion Scale (SCS). In addition goodness-of-fit, we aimed assess strength and replicability three factorial solutions, quality effectiveness scoring schemes scale (i.e., total score, two subscale scores, six scores). Methods Participants were 1508 Spanish-speaking community-dwelling adults ( M = 34.94 years, SD 15.02). Data examined by means conjoint strategy using Rasch modeling, non-linear factor analysis, exploratory bifactor parallel analysis. A procedure for selecting optimal set items that must be used compute individual’s scores used. Results unidimensional solution showed marginal model fit (RMSR .089), both two-group six-group solutions good .043 .019, respectively). However, only two-factor interpretable replicable structures, high-quality effective measurement purposes. Subscale derived from primary factors did not show adequate properties. It observed information provided 10 redundant had already been other 16 items. Conclusions Good is neither sufficient nor necessary justify use scheme. Goodness-of-fit statistics should complemented an metric resulting when proposing SCS schemes.
