This study addresses the relationship between performance validity and treatment outcome in a sample of patients with somatic symptom and related disorders (SSRD). A retrospective analysis was performed in a sample of 337 patients with SSRD who received treatment. Interaction effects were determined between performance validity test (PVT) performance and raw change scores, reliable change index and clinical change of depression, anxiety and physical symptoms.

Performance below the actual abilities of the examinee can be measured using performance validity tests (PVTs). PVT failure negatively impacts the quality of the neuropsychological assessment. In our study, we addressed this issue by providing a brief corrective statement regarding invalidity to improve test-taking behavior.

Performance validity tests (PVTs) are used to measure the validity of the obtained neuropsychological test data. However, when an individual fails a PVT, the likelihood that failure truly reflects invalid performance (i.e.

Objective: There is limited research examining the impact of the validity of cognitive test performance on treatment outcome. All known studies to date have operationalized performance validity dichotomously, leading to the loss of predictive information. Using the range of scores on a performance validity test (PVT), we hypothesized that lower performance at baseline was related to a worse treatment outcome following cognitive behavioral therapy (CBT) in patients with Chronic Fatigue Syndrome (CFS) and to lower adherence to treatment.

Performance Validity Tests (PVTs) are used to measure the credibility of neuropsychological test results. Until now, however, a minimal amount is known about the effects of feedback upon noncredible results (i.e.

Noncredible symptom reports hinder the diagnostic process. This fact is especially the case for medical conditions that rely on subjective report of symptoms instead of objective measures. Mild cognitive impairment (MCI) primarily relies on subjective report, which makes it potentially susceptible to erroneous diagnosis.
