Practitioners who conduct assessments of parenting capacity for the courts are faced with the challenge of determining the extent to which positive self-presentation by parents distorts test findings. This study examined positive self-presentation bias on commonly used psychological tests in cases referred following removal of children from the home because of abuse or neglect. Substantial positive self-presentation bias was apparent on the measures examined, and parents who presented themselves positively on one test tended to do so on others. Intellectual functioning did not account for these findings. The results demonstrate the pervasive problem of positive self-presentation bias in compromising the validity of test results in this population. Recommendations for conducting clinical assessments with this population are offered, including direction for the use and interpretation of psychological tests
