An initial CFA with the ICQ-30 formed the basis for the selection of the items to be included in the ICQ-15. Cronbach’s alpha coefficients were computed for the ICQ-15.

Three confirmatory factor analyses (CFA) were conducted in order to develop and validate the ICQ-15. Data were collected from 2,009 participants. The purpose of the current study is to develop and validate a brief version of the ICQ among a large adult sample that is representative of the German general population. Two versions comprising 40 and 30 items, respectively, are available in German.

The Interpersonal Competence Questionnaire (ICQ) developed by Buhrmester and colleagues ( 1988) in the US assesses the multidimensional construct of social competence via five distinct, but related subscales.
