Schalling-Sifneos Personality Scale: Findings and Recommendations

Abstract
Noting concerns for the measurement of alexithymia, the present study attempted to provide descriptive data on the Schalling-Sifneos Personality Scale (SSPS); to replicate previous factor-analytic findings on the SSPS, and to suggest an alternative to the present method of scoring the SSPS. A sample of 430 undergraduates completed the SSPS. The distribution of scores on the SSPS was approximately normal; that the factor structure of the SSPS is robust over samples, and that factor analyses identified factors representing characteristics consistent with those described by alexithymia. A subsequent factor analysis was performed to identify questionnaire items most relevant to the measurement of alexithymia. Nine questions were identified and were used in a revised scoring system. The distribution of revised scores is also approximately normal. Evidently, this revised system is a more sensitive indication of the presence of alexithymia.
