An examination of shared variance in self-report and objective measures of attention in the incarcerated adult population.

Objective: The present study was designed to test some assumptions about screening procedures for ADHD in adults.

Method: Twenty-eight incarcerated male adults completed a self report scale of attention deficits as a part of an examination of attention and reading skills. Further assessment of attention included a battery of tests that assessed vigilance, attention shifts, and other aspects of cognitive control.

Results: Fifty seven percent of the sample showed test performance indicating a high probability of ADHD. Correlation analyses yielded significant effects for self report scales and objective tests of attention.

Conclusion: The results support the assumption that the self report measures share a significant part of the variance with tests of attention commonly used in clinical assessment. However, the risk of making both false positive and false negative inferences about ADHD is present, as the specificity and the sensitivity of the rating scale needs to be further explored.
