Self-Control Behind Bars: a Validation Study of the Grasmick et al. Scale
نویسندگان
چکیده
Much empirical support of self-control theory is based on the 24-item scale conceptualized by Grasmick and his colleagues. This study examined the dimensionality of the scale. Exploratory factor analysis, confirmatory factor analyses, and a structural equation model (SEM) produced results that are discordant with much prior research. The Grasmick et al. scale was not unidimensional, more complex theoretical iterations failed to meet most goodness-of-fit statistics, and considerable refinement via modification indices was needed before a measurement model that fit the data could be found. Further refinement is required to justify it as the quintessential measure of self-control.
