MMPI-2 Clinical Scale 6 (Paranoia) and Restructured Clinical Scale 6 (Ideas of Persecution) in Child Custody Litigants

Abstract

The MMPI-2 is the most frequently used psychological test with parents undergoing child custody evaluations (CCE's). Studies of parents who completed the MMPI-2 in the CCE context have consistently found that, on average, parents portray a very favorable image of themselves as both virtuous and psychologically well-adjusted. Also, on average, Clinical Scale 6 (Paranoia) and its counterpart on the Restructured Clinical Scales, RC6, "Ideas of Persecution", have been the most frequently elevated of the clinical scales on the MMPI-2 in samples of child custody litigants, albeit, the reported scores on these scales were well within the norm. This paper examines the significance of clinically elevated scores on Scale 6 (and RC6) in parents undergoing CCE's, with consideration of both contextual and psychometric features. Based on these considerations, this writer suggests that custody evaluators may encounter the paradox that some parents whose clinical profile suggests mistrust and suspiciousness in interpersonal relations may actually trust enough to report their perceptions in a candid and forthcoming manner. Some of these parents may not be mistrustful in general and might not be inclined to model or influence their children toward the development of mistrust. In contrast, other parents may respond to the test in a more defensive and deceptive manner resulting in a "normal" clinical profile, which may be specific to the evaluation context, but may also reflect moral righteousness and a more insidious tactic. The custody evaluator is advised to use caution when interpreting clinically elevated scores on the MMPI-2.
