“…Of the 860 participants, we omitted 163 from these analyses leaving a total sample of 697: 142 were omitted because they completed the survey either so quickly (< 15 minutes; n = 6) or so slowly (> 2 hours, n = 136), that it raised doubt about the validity of their assessments, and 23 were eliminated because they achieved a T score of 90 or greater (Goodwin, Sellbom, & Arbisi, 2013) on an index of symptom over-reporting (the revised Infrequency Psychopathology [Fp-r] validity scale on the Minnesota Multiphasic Personality Inventory-2 Restructured Form [MMPI-2-RF; Tellegen & Ben-Porath, 2008]), which was administered to address concerns about the lack of experimenter control inherent in internet-based methods. These items were administered in random order along with a subset of other MMPI-2 items (for a total of 51 MMPI-2 items) that are not the focus of this investigation.…”

The Dissociative Subtype of PTSD Scale: Initial Evaluation in a National Sample of Trauma-Exposed Veterans

et al. 2015

The fifth edition of the Diagnostic and Statistical Manual (DSM-5) includes a dissociative subtype of posttraumatic stress disorder (PTSD), but no existing measures specifically assess it. This paper describes the initial evaluation of a 15-item self-report measure of the subtype called the Dissociative Subtype of PTSD Scale (DSPS) in an on-line survey of 697 trauma-exposed military veterans representative of the US veteran population. Exploratory factor analyses of the lifetime DSPS items supported the intended structure of the measure consisting of three factors reflecting derealization/depersonalization, loss of awareness, and psychogenic amnesia. Consistent with prior research, latent profile analyses assigned 8.3% of the sample to a highly dissociative class distinguished by pronounced symptoms of derealization and depersonalization. Overall, results provide initial psychometric support for the lifetime DSPS scales; additional research in clinical and community samples is needed to further validate the measure.

“…The Minnesota Multiphasic Personality Inventory-Restructured Form (MMPI-2-RF; Tellegen and Ben-Porath 2008/2011) is a widely-used broadband instrument within the VA and research has consistently supported the reliability and validity of scores on MMPI-2-RF scales in veterans and military service members (e.g., Russo 2018). The validity scales consistently discriminate between valid and invalid patterns of responding (Goodwin et al 2013;Nelson et al 2011;Sellbom et al 2012b;Shura et al 2017), offering a means to evaluate the potential for response bias within the VA (Ray 2017). Similarly, the substantive scales are useful in predicting diagnostic presentations and identifying important clinical concerns (Koffel et al 2012;Gottfried et al 2014;Sellbom et al 2012a;Wolf et al 2008).…”

This investigation provides descriptive information on substantive scale scores from the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) across four common service locations within Veterans Affairs (VA): PTSD clinical team, individual substance use treatment, primary medical care, and residential polytrauma rehabilitation. Test protocols for these four service settings are drawn from a national sample of all MMPI-2-RF and converted MMPI-2 administrations between January 1, 2008 and May 31, 2015 using the VA Mental Health Assist system at any VA across the United States. Frequency of substantive scale elevation and descriptive findings are examined. Results of this investigation suggest that there are differences between VA service locations on the MMPI-2-RF substantive scales, the magnitude of difference depends on the substantive scale examined, and the pattern of elevation within service location follows common clinical concerns for the settings. Implications for the clinical use, and research with, the MMPI-2-RF within the VA and with the veteran population are discussed.

“…For example, Garcia, Franklin, and Chambliss (2010) found that 79% of treatment-seeking Operation Enduring and Iraqi Freedom (OEF/OIF) Veterans with a PTSD diagnosis had elevated scores on over-reporting scales of the Minnesota Multiphasic Personality Inventory II (MMPI-2). Elevated scores were also found on the over-reporting scales of the newly revised MMPI-2 Restructured Form (MMPI-2-RF) in a cross-cohort sample of compensation-seeking Veterans diagnosed with PTSD (Goodwin, Sellbom, & Arbisi, 2013). Though it is now established that an over-reporting response style is frequently observed in PTSD patients, the reasons for this effect remains a contentious topic.…”

The current study investigated in a sample of OEF/OIF Veterans how a symptom over-reporting response style might influence the association between PTSD diagnostic status and color-naming response latency for trauma-related stimuli during the Modified Stroop Task (i.e., the Modified Stroop Task effect, MST effect). It was hypothesized that, if an over-reporting response style reflected feigning or exaggerating PTSD symptoms, an attenuated MST effect would be expected in over-reporters with PTSD as compared with PTSD-diagnosed Veterans without an over-reporting style. If, however, over-reporting stemmed from high levels of distress, the MST effect might be greater in over-reporters compared to those with a neutral response style. The results showed that Veterans with PTSD and an over-reporting response style demonstrated an augmented MST effect in comparison to those with a more neutral style of response. Over-reporters also reported greater levels of psychopathology, including markedly elevated reports of dissociative experiences. We suggest that dissociation-prone over-reporters may misattribute emotional distress to combat experiences leading to the enhanced MST effect. Other possible explanations for these results are also discussed.
