Latent structure of the Postconcussion Syndrome Questionnaire

Article Abstract:

A four-factor model explains the latent factor structure of Postconcussion Syndrome Questionnaire (PCS). A confirmatory factor analytic study shows that the three-, four- and five-factor models are superior to a unidimensional model or a 43-factor model. The four-factor model better suits to the PCS latent factor structure than the three- and five-factor models. The four factors are clusters of psychological, somatic, cognitive and infrequent complaints.

Interrelationship of MMPI-2 validity scales in personal injury claims

Article Abstract:

A study of 289 NY personal injury and compensation claimants revealed that they feigned psychological disorders by resorting to inaccurate responses and exaggeration of symptoms. MMPI-2 scales including Fake Bad Scale, total of obvious minus subtle scales and the MMPI Dissimulation Scale-revised were employed in ascertaining the factual status of the compensation claims by precisely computing the sensitivity of each score of the validity scales.

Neurotoxic complaint base rates of personal injury claimants: implications for neuropsychological assessment

Article Abstract:

Psychologists should keep in mind the base rate of symptoms in those prone to litigation and use caution in relying on self-reports as evidence of injury when these people litigate. Personal injury claimants in a survey had more neurotoxic and neuropsychologic complaints than subjects with head trauma or toxic exposure in their medical histories.
