The Parents Preference Test (PPT) is a graphical test comprised of 24 easy to understand images of daily family life, which is widely used in forensic assessments of parenting skills. Nevertheless, the PPT lacks validity scales to detect participants' attitudes toward the test; this is an important oversight, as the tendency to demonstrate faking-good parenting behaviors is common in child custody litigants. Study 1 aimed at identifying the differences in PPT responses between a

Chi-square goodness of fit tests showed significant differences in answer preferences between groups in 11 vignettes (almost half of the total PPT items). Study 2 aimed at developing an index to detect faking-good behaviors. On the 11 vignettes in which significant differences in answer preferences were found in Study 1, the alternatives chosen with the highest frequency by the forensic group were added to an index called the "Conforming Parenting Index" (CPI). The area under the curve (AUC) of a receiver operating characteristic (ROC) curve for a sample of 58 participants who completed the PPT under both standard and faking-good instructions demonstrated good classification accuracy (AUC= .813).
