Erroneous conclusions: The impact of failing to identify invalid symptom presentation when conducting adult attention-deficit/hyperactivity disorder (ADHD) research.

Invalid symptom report during assessment confounds the differential diagnosis process. This study examined differences in neuropsychological functioning between individuals diagnosed with attention-deficit/hyperactivity disorder (ADHD) and depression and/or anxiety disorders before and after participants meeting diagnostic criteria for malingered neurocognitive dysfunction were excluded. One hundred sixty-one adult patients undergoing ADHD assessment [ age 27.

The impact of failing to identify suspect effort in patients undergoing adult attention-deficit/hyperactivity disorder (ADHD) assessment.

[Correction Notice: An Erratum for this article was reported in Vol 28(10) of (see record 2016-22725-001). In the article, the penultimate sentence of the abstract should read “These results suggest that a significant percentage of those making a suspect effort will be diagnosed with ADHD using the most commonly employed assessment methods: an interview alone (71%); an interview and ADHD behavior rating scales combined (65%); and an interview, behavior rating scales, and most continuous performance tests combined (62%).” All versions of this article have been corrected.

Reliable Digit Span: a systematic review and cross-validation study.

Reliable Digit Span (RDS) is a heavily researched symptom validity test with a recent literature review yielding more than 20 studies ranging in dates from 1994 to 2011. Unfortunately, limitations within some of the research minimize clinical generalizability. This systematic review and cross-validation study was conducted to address these limitations, thus increasing the measure's clinical utility.

Evaluation of the appropriateness of multiple symptom validity indices in psychotic and non-psychotic psychiatric populations.

Although it is recognized that significant cognitive deficits are inherent in many psychiatric disorders, there is minimal research on whether the deficits can cause a failing score on symptom validity tests (SVTs). The performances of 104 and 178 patients with psychotic disorders and non-psychotic psychiatric disorders, respectively, on seven SVTs were examined. Analyses indicate that most of these SVTs have specificity rates of 90% or better for both clinical groups.

Validation of the sentence repetition test as a measure of suspect effort.

It has been suggested that the Sentence Repetition Test (SRT) could serve as an adequate embedded symptom validity measure identifying suspect effort during neuropsychological testing. However, very little research has examined sensitivity and specificity rates when using this measure in a variety of clinical settings. The SRT was administered to 1031 patients referred for neuropsychological assessment in outpatient, inpatient, and independent medical evaluation settings.

Effects of seasonal allergic rhinitis on fatigue levels and mood.

Objective: Many allergy patients complain of fatigue, moodiness, and dysphoria during their allergy seasons. This study evaluated the effect of symptomatic allergic rhinitis on both fatigue level and mood.

Method: Symptomatic ragweed allergic rhinitis patients on no medications and healthy control subjects completed the Multi-Dimensional Fatigue Inventory and the Positive Affect-Negative Affect mood rating scales in an in-out-in ragweed season research design.
