criteria were administered the TIP-1 as part of their clinical workup.MANOVA revealed a significant overall difference in TIP-1 performance between the ADHD and control groups ( F = 2.7; P =.0020.A series of univariate analyses demonstrated that ADHD subjects had slower RT than controls on all measures.There were no significant differences between the groups on another executive measure (Trail B).The findings suggest that the TIP-1 may be useful in the evaluation of adults with question of ADHD and possibly with other subjects where a more challenging and sensitive measure of executive functioning is required. EFFORT/MOTIVATIONDeclining CARB failure rates over 6 years of testing: what's wrong with this picture?Allen LM, Green P Coaching of patients on Symptom Validity Tests is now of major concern in clinical neuropsychological assessment.However, the influence of coaching on results from a large sample of patients has not been previously reported.In this study, failure rates on CARB and the WMT were assessed in 904 consecutive compensation claimants over a 6-year period.While failure rates on WMT effort measures did not change over this period, CARB failure rates declined significantly based on total CARB score ( P < .002),failure on any CARB block ( P < .0001),or failure defined by being more than 3.7 standard deviations below a combined group of patients with moderate to severe TBI or neurological injuries ( P < .0001).Changes in demographic and other sample variables that might be expected to account for such a difference were not observed.It is possible that the marked decrease in CARB failure rates over time was a result of information about CARB being given to patients by third parties prior to testing.The differential changes in failure rates on CARB and WMT could be related to their differing levels of vulnerability to coaching.In this practice, CARB was introduced 3 years before WMT.It is also possible that coaching begins to have an impact several years after a test is introduced and this may have contributed to the differences observed.Suggestions are offered that may strengthen future SVT research involving clinical samples.
