Abstract
Objective
The aim of this study was to refine the YSQ-L3 by identifying the most statistically and clinically appropriate items for each Early Maladaptive Schema (EMS) using Rasch analysis.
Method
A Rasch analysis was undertaken on a large sample (N = 838) that included a heterogeneous clinical sample (N = 574) and a smaller non-clinical group (N = 264).
Results
Overall, 116 out of 232 items showed misfit across a number of statistical indicators. After the removal of these items, the fit improved for all subscales and showed good (.74) to excellent (.86) reliability with the exception of Enmeshment (.57). In line with previous research, items originally measuring Punitiveness were found to better fit two separate subscales, Punitiveness (Self) and Punitiveness (Other). Similarly, items assessing Emotional Inhibition fit better as two different constructs; Emotional Constriction, reflecting an over-control related to shame/embarrassment of showing emotions, and Fear of Losing Control, related to anxiety of the consequences if emotions are not contained.
Conclusion
This is the first study to apply a rigorous methodological process to item selection from the YSQ-L3. The findings of this study are significant given the wide use of this scale cross-culturally in both clinical and research settings and offer a possible alternative to the current short form.
