Psychometric properties of the Portuguese Self-Monitoring Scale: A reduced item version.

This study aimed to contribute to the adaptation of the Self-Monitoring Scale for a Portuguese sample and the examination of the possibility of reducing the scale's length. Considering the psychometric inconsistency of the scale reported in the literature, several analysis criteria to identify the number of factors to be retained were considered. The study included 791 Portuguese men and women aged 17 to 61 years. Data analysis included descriptive statistics, confirmatory factor analysis to assess construct validity, Cronbach's alpha to assess internal consistency, and fit indices (based on IRT). The results indicate a two-dimensional structure with a reduction to 9 items, which shows good values for validity and fit. This study proposes a reduced version of the self-monitoring scale for a Portuguese sample, considering that the use of this method is valuable to identify how individuals differ in the way they present themselves in social situations.
