Psychometric characteristics of the Italian Clinical Depression Questionnaire using a 5-point rating scale with undergraduates.
The aim was to investigate the psychometric properties of a proposed experimental version of the 1979 Italian adaptation of the Clinical Depression Questionnaire (Krug & Laughlin, 1976). This version is composed of an increased number of choice alternatives (5 instead of 3), tested with 240 Italian undergraduates. An exploratory item-factor analysis yielded one factor, which accounted for 28.2% of the variance. Analysis of the relationship between this version and an experimental one in 2002 of the 1979 Italian edition of the Anxiety Scale Questionnaire showed the corrective factor was not effective in increasing the discriminative power of the questionnaire for anxiety.
