Reliability Coefficient: Internal Consistency
For the reliability analysis of the Deenz Multidimensional Schizoid Personality Scale (DMSPS-28), Cronbach's alpha was employed to assess the internal consistency of the scale across its facets. The following table presents the Cronbach's alpha coefficients for each facet:
FacetCronbach's Alpha
Social Detachment0.84
Anhedonia0.79
Blunted Affect0.81
Solitude0.73
Friendlessness0.78
Cronbach's alpha coefficients ranging from 0.70 to 0.95 are generally considered acceptable for research purposes, indicating satisfactory internal consistency reliability. In this study, all facets of the DMSPS-28 demonstrated good reliability, with alpha coefficients ranging from 0.73 to 0.84, suggesting that the items within each facet are strongly correlated with each other.
