TLDR
This study supports the use of the IOP-29 together with the TOMM in multimethod symptom validity assessments and provides initial evidence that both tests can be used also in Portugal.Abstract:
This study tested whether combining the Inventory of Problems - 29 (IOP-29) with the Test of Memory Malingering (TOMM) would increase sensitivity in the detection of experimentally feigned mental health problems, compared to using either test alone. Additionally, it also evaluated (a) the effects of administration order of these two tests and (b) the cultural and linguistic applicability of these tests to a European Portuguese population. The IOP-29 and TOMM were administered to a community sample of 100 nonclinical, adult volunteers from Portugal, with the instruction to feign mental health problems. Half were instructed to feign mild traumatic brain injury (mTBI) symptoms, half were instructed to feign major depression. Administration order had no effects on the tests' scores, and both measures produced excellent sensitivity values, ranging from .82 to .98 for the TOMM, and from .88 to 1.00 for the IOP-29, when using standard a priori cutoff scores. More importantly, combining the results of TOMM with those of IOP-29 notably increased sensitivity compared to using either test alone. This study thus supports the use of the IOP-29 together with the TOMM in multimethod symptom validity assessments and provides initial evidence that both tests can be used also in Portugal.read more

TL;DR: The newly introduced FCR trial has the potential to enhance the existing arsenal of EVIs within the HVLT-R but must demonstrate its ability to differentiate genuine impairment from non-credible responding before it can be recommended for clinical use.

Convergent and discriminant validation by the multitrait-multimethod matrix.
TL;DR: This transmutability of the validation matrix argues for the comparisons within the heteromethod block as the most generally relevant validation data, and illustrates the potential interchangeability of trait and method components.
