“…An overwhelming proportion of child custody evaluations involve psychometric measures, which are predominantly used to assess the personality characteristics and functioning of litigants. One such measure, the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) (Butcher et al, 2001), is a well-established psychological instrument that is frequently used in forensic assessment (Burla et al, 2019; Mazza et al, 2019a; Mazza, Monaro et al, 2019b; Mazza et al, 2019c; Mazza, Monaro et al, 2020; Roma et al, 2013; Roma et al, 2016; Roma et al, 2018; Roma et al, 2019a; Roma et al, 2019b; Roma et al, 2020). Only two studies have analyzed the MMPI-2 profiles of PA subjects.…”

Parental alienation (PA) describes a family dynamic in which a parent engages in behaviors that are likely to foster a child’s unjustified rejection of the other parent. PA is considered a particular form of child psychological maltreatment with both short- and long-term negative consequences. Parents who attempt to turn a child against the other parent in cases of separation/divorce can be difficult to identify. Increasing our understanding of the personality features of these parents via psychological assessment may enable us to identify PA more quickly following the onset of abuse. In the present study, the personality characteristics of mothers engaging in PA were examined through a comparative analysis of MMPI-2 profiles. The results indicated that alienating mothers presented higher moral virtue and extroversion. They were more vulnerable to interpersonal stress and they demonstrated unsuccessful self-representation. The findings provide a preliminary model for understanding the profile of mothers who engage in PA.

“…A further example is the Inventory of Problems-29 (IOP-29) [22], a 29-item easy-to-use measure of non-credible mental and cognitive symptoms. Studies using this instrument yielded encouraging results in the detection of malingering [23,24] and indicated that it can be used in a multimethod symptom validity assessment along with TOMM [25]. Another example is the Structured Inventory of Malingered Symptomatology (SIMS) [26] is a 75-item multi-axial self-report questionnaire validated with clinical-forensic, psychiatric, and non-clinical populations.…”

Indicators to distinguish symptom accentuators from symptom producers in individuals with a diagnosed adjustment disorder: A pilot study on inconsistency subtypes using SIMS and MMPI-2-RF

In the context of legal damage evaluations, evaluees may exaggerate or simulate symptoms in an attempt to obtain greater economic compensation. To date, practitioners and researchers have focused on detecting malingering behavior as an exclusively unitary construct. However, we argue that there are two types of inconsistent behavior that speak to possible malingering—accentuating (i.e., exaggerating symptoms that are actually experienced) and simulating (i.e., fabricating symptoms entirely)—each with its own unique attributes; thus, it is necessary to distinguish between them. The aim of the present study was to identify objective indicators to differentiate symptom accentuators from symptom producers and consistent participants. We analyzed the Structured Inventory of Malingered Symptomatology scales and the Minnesota Multiphasic Personality Inventory-2 Restructured Form validity scales of 132 individuals with a diagnosed adjustment disorder with mixed anxiety and depressed mood who had undergone assessment for psychiatric/psychological damage. The results indicated that the SIMS Total Score, Neurologic Impairment and Low Intelligence scales and the MMPI-2-RF Infrequent Responses (F-r) and Response Bias (RBS) scales successfully discriminated among symptom accentuators, symptom producers, and consistent participants. Machine learning analysis was used to identify the most efficient parameter for classifying these three groups, recognizing the SIMS Total Score as the best indicator.

“…According to Viglione et al (2017), this set of 29 items survived multiple cross-validations throughout a lengthy period of test development in which an initial pool of 245 items addressing 27 feigning strategies were evaluated. This procedure is probably one of the reasons why, despite its brevity, the IOP-29 seems to be a highly effective SVT (Gegner et al, 2021;Giromini et al, 2018;Ilgunaite et al, 2020;Roma et al, 2020;Viglione et al, 2017;Winters et al, 2020).…”

“…Its research profile is accumulating, a hallmark for use in legal settings" (Young et al, 2020, p. 9). Although the IOP-29 was published only relatively recently in 2017 (Viglione et al, 2017), all 12 published studies since then support its validity and effectiveness (Gegner et al, 2021;Giromini et al, 2018Giromini et al, , 2020aIlgunaite et al, 2020;Roma et al, 2020;Viglione et al, 2017Viglione et al, , 2019Winters et al, 2020). Specifically, the results of these studies suggest that (a) the validity and classification accuracy of the IOP-29 compares favorably to that of popular measures like the Structured Inventory of Malingered Symptomatology (SIMS; Smith & Burger, 1997) (Giromini et al, 2018) or Rey Fifteen-Item Test (FIT; Lezak, 1995;Rey, 1941) (Gegner et al, 2021); (b) the IOP-29 is similarly valid when addressing feigning of different conditions such as depression, neuropsychological impairment, psychosis and/or PTSD (e.g., Giromini et al, 2020b;Ilgunaite et al, 2020;Winters et al, 2020); (c) the validity of the IOP-29 is maintained both when adopting a simulation/analogue (e.g., Gegner et al, 2021) and when relying on a known-groups comparison (Roma et al, 2020) research paradigm; (d) the IOP-29 yields incremental validity when used in combination with other SVTs (Giromini et al, 2019) or PVTs (Giromini et al, 2020a); (e) the IOP-29 preserves its effectiveness also when used outside the USA, in countries such as Australia (Gegner et al, 2021), the UK (Winters et al, 2020), Italy (Giromini et al, 2018), Portugal (Giromini et al, 2020a), or Lithuania (Ilgunaite et al, 2020).…”

While the psychometric equivalence of computerized versus paper-and-pencil administration formats has been documented for some tests, so far very few studies have focused on the comparability and validity of test scores obtained via in-person versus remote administrations, and none of them have researched a symptom validity test (SVT). To contribute to fill this gap in the literature, we investigated the scores of the Inventory of Problems-29 (IOP-29) generated by various administration formats. More specifically, Study 1 evaluated the equivalence of scores from nonclinical individuals administered the IOP-29 remotely (n = 146) versus in-person via computer (n = 140) versus in-person via paper-and-pencil format (n = 140). Study 2 reviewed published IOP-29 studies conducted using remote/online versus in-person, paper-and-pencil test administrations to determine if remote testing could adversely influence the validity of IOP-29 test results. Taken together, our findings suggest that the effectiveness of the IOP-29 is preserved when alternating between face-to-face and online/remote formats.
