The many faces of malingering and participant response strategies: new methodologies in the Attachment and Clinical Issues Questionnaire (ACIQ).

Four studies created malingering and response bias scales for a new test battery, the Attachment and Clinical Issues Questionnaire (ACIQ). In the first calibration study, a new approach to identifying fake good and fake bad respondents was outlined. In Study 2, this scale was cross validated in a within-subjects design that also found only weak correlations between the scales of the ACIQ and measures of social desirability. The third study developed a method violator scale (one who responds randomly to the content of the scales due to carelessness, low IQ, etc.). It was tested by Monte Carlo and empirical studies. The fourth study combined the two cross validation studies to offer clear cutoffs for the practitioner. These studies successfully led to the creation of malingering and response bias scales for the ACIQ and also introduced new methods that could be adapted to other instruments.
