摘要

We aimed to develop and validate a forced-choice screening of personality disorder, controlling for social desirability. We adopted a Likert rating format screening previously developed (Dimensional Clinical Personality Inventory – screening version; IDCP-SV) and Brown’s forced-choice model. Our sample included 2,146 adults as follows: 755 to establish the factor solution of the IDCP-SV, 107 to estimate the item’s social desirability levels, and 1,284 who answered the format-choice format of IDCP-SV, and a subsample (n = 657) who also answered the Likert format, and other personality measures. Results provided evidence that the forced choice of the IDCP-SV was less susceptible to social desirability than the Likert format, presenting reasonable associations with external measures. We demonstrated that the forced-choice format is less impacted by social desirability than the Likert format, which renders more reliable scores.
