Differentiating overreporting and extreme distress: MMPI-2 use with compensation-seeking veterans with PTSD

This purpose of this study was to examine overreporting on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) in compensation-seeking veterans with posttraumatic stress disorder (PTSD). A sample of veterans tested during a V.A. hospital compensation and pension exam were given the MMPI-2 and measures of PTSD, depression, and combat exposure. Veterans MMPI-2s were only included in the analyses if their profile was extremely exaggerated, as measured by an F scale T score above 80, did not elevate the MMPI-2 VRIN and TRIN scales, and had a primary diagnosis of PTSD (n = 127). Using the Infrequency-Psychopathology, F(p), scale to distinguish overreporting from distress, it was found that 98 veterans elevated profiles due to distress, whereas 29 elevated due to overreporting, F(p) below and above 7, respectively. Differences between groups on MMPI-2 clinical scales and the other measures were assessed. Implications of these findings for assessing veteran response style and using the MMPI-2 with a PTSD population are discussed.

Assessment of response style in combat veterans seeking compensation for posttraumatic stress disorder

This study examined response styles of veterans seeking compensation for PTSD (N = 204). Veterans were classified as having a valid or overreporting response style based on their scores on three MMPI-2 validity scales that measure overreporting F, F(p), F-K. Sixteen percent of veterans had valid scores on all three scales. The number of veterans classified as having an overreporting response style differed depending on which scale was used. This finding highlights the importance of using multiple validity scales to measure response style. Veterans who were and were not classified as overreporters were compared on measures of combat exposure, PTSD, and depression.

Face to face but not in the same place: A pilot study of prolonged exposure therapy

ABSTRACT This pilot study examined use of smartphone technology to deliver prolonged exposure (PE) therapy to patients with posttraumatic stress disorder (PTSD) with geographic limitations hindering in-person therapy. The primary goal was to examine the feasibility and acceptability of using video teleconferencing (i.e., computer-based and iPhone 4 streaming technology), with a secondary goal of examining clinical outcomes of PE delivered via teleconferencing compared with treatment as usual (TAU) on PTSD and depressive/anxious symptom reduction. Rural veterans (N = 27) were randomized to receive PE by computer teleconferencing at a Veterans Administration community clinic, PE by an iPhone issued for the duration of the study, or TAU provided by a referring clinician. To examine the research goals, we collected data on the number of referrals to the study, number of patients entering the study, and number completing psychotherapy and documented pragmatic and technical issues interfering with the ability to use teleconferencing to deliver PE; results are discussed. In addition, measures of symptom change examined clinical outcomes. Results indicated decreases in PTSD symptoms in veterans who completed PE therapy via teleconferencing; however, there was significantly more attrition in these groups than in the TAU group.

Associations between lower order anxiety sensitivity dimensions and DSM-5 posttraumatic stress disorder symptoms

Abstract Anxiety sensitivity (AS), a well-established individual difference variable reflecting a tendency to fear bodily sensations associated with arousal, has been implicated in the development and maintenance of posttraumatic stress disorder (PTSD). Despite these associations, little research has examined the relations between AS subfactors (eg physical, cognitive, and social) and PTSD symptoms and none have examined these associations in the context of DSM-5 (Diagnostic Statistical Manual of Mental Disorders, Fifth Edition) PTSD clusters (ie intrusion, avoidance, negative alterations in cognitions/mood, and arousal). Participants included 50 veterans presenting to an outpatient Veteran Affairs Clinic for psychological services. Upon intake, veterans completed a brief battery of self-report questionnaires to assist with differential diagnosis and treatment planning. Results revealed unique associations between lower order AS dimensions, in particular the cognitive concerns dimension, and all four DSM-5 PTSD symptom clusters. Given the malleable nature of AS cognitive concerns, as well as the growing number of veterans in need of care, future research should determine the extent to which targeting this cognitive risk factor reduces PTSD symptom severity among veterans.

Posttraumatic stress disorder and suicidal ideation, plans, and impulses: The mediating role of anxiety sensitivity cognitive concerns among veterans.

BACKGROUND Although the relationship between posttraumatic stress disorder (PTSD) and suicide has been firmly established, research on underlying mechanisms has been disproportionately low. The cognitive concerns subscale of anxiety sensitivity (AS), which reflects fears of cognitive dyscontrol, has been linked to both PTSD and suicide and thus may serve as an explanatory mechanism between these constructs. METHODS The sample consisted of 60 male veterans presenting to an outpatient Veteran Affairs (VA) clinic for psychological services. Upon intake, veterans completed a diagnostic interview and brief battery of self-report questionnaires to assist with differential diagnosis and treatment planning. RESULTS Results revealed a significant association between PTSD symptom severity and higher suicidality (i.e., ideation, plans, and impulses), even after accounting for relevant demographic and psychological constructs. Moreover, AS cognitive concerns mediated this association. LIMITATIONS Limitations include the small sample size and cross-sectional nature of the current study. CONCLUSIONS These findings add considerably to a growing body of literature examining underlying mechanisms that may help to explain the robust associations between PTSD and suicide. Considering the malleable nature of AS cognitive concerns, research is needed to determine the extent to which reductions in this cognitive risk factor are associated with reductions in suicide among at risk samples, such as those included in the present investigation.

Examining potential overlap of DSM-5 PTSD criteria D and E.

The Diagnostic and Statistical Manual, Fifth Edition-5 (DSM-5) has adopted a four-factor symptom model for Posttraumatic Stress Disorder (PTSD) that includes new symptom additions in criterion D (D2, D3, D4), negative alterations in cognition and mood. This article examines potential overlapping endorsement of these symptoms amongst one another and with the behavioral symptoms within PTSD criterion E (E1 and E3; alterations in arousal and reactivity), through the lenses of cognitive-behavioral theory. Responses of veteran participants (N=320) completing the PTSD Checklist-5 were used to determine overlap in symptom reporting. We conducted a series of direct logistic regressions to determine the predictive ability of meeting the criterion D or E symptoms based on endorsement of the target D symptoms (D2, D3, D4). Results suggest that the new cognitive and emotional symptoms of criterion D have significant overlapping content, and that thought-related symptoms are often endorsed in conjunction with their behavioral counterpoint (D2/E3; D4/E1). Our results suggest that DSM-5 criterion D symptoms may not be central to the diagnostic structure of PTSD. These symptoms add complexity and difficulty to diagnosing PTSD without adding much unique content.

27 ways to meet PTSD: Using the PTSD-checklist for DSM-5 to examine PTSD core criteria

Posttraumatic stress disorder (PTSD) has been criticized for including symptoms that substantially overlap with other depression and anxiety disorders. To address this concern, Brewin et al. (2009) reformulated the diagnosis around a core symptom set. Although several studies have examined the utility of the core criteria in predicting diagnostic status, none have done so using a self-report screening instrument. The sample included 617 veterans presenting for outpatient psychological services. As a part of the intake process, veterans completed the PTSD Checklist for DSM-5 (PCL-5) and were assessed using the Clinician Administered PTSD Scale for DSM-5 (CAPS-5). Veterans meeting core criteria on the PCL-5 were over 22 times more likely to meet PCL-5 diagnosed PTSD than veterans who met the core criteria on the PCL-5 but did not meet PCL-5 diagnosed PTSD (OR = 22.94; CI [12.76, 41.25]). Further, veterans who met core criteria on the PCL-5 were over 2 times more likely (OR = 2.34; 95.0% CI [1.53, 3.59]) to meet CAPS-5 diagnosed PTSD than veterans who met the core criteria on the PCL-5 but did not meet CAPS-5 diagnosed PTSD. Findings from the current study have implications for the assessment and classification of PTSD.

Examining the latent structure mechanisms for comorbid posttraumatic stress disorder and major depressive disorder

BACKGROUND Posttraumatic stress disorder (PTSD) is a complex psychiatric illness that can be difficult to diagnose, due in part to its comorbidity with major depressive disorder (MDD). Given that researchers have found no difference in prevalence rates of PTSD and MDD after accounting for overlapping symptoms, the latent structures of PTSD and MDD may account for the high comorbidity. In particular, the PTSD Negative Alterations in Cognition and Mood (NACM) and Hyperarousal factors have been characterized as non-specific to PTSD. Therefore, we compared the factor structures of the Diagnostic and Statistical Manual of Mental Disorders, 5thedition (DSM-5) PTSD and MDD and examined the mediating role of the PTSD NACM and Hyperarousal factors on the relationship between MDD and PTSD symptom severity. METHODS Participants included 598 trauma-exposed veterans (Mage = 48.39, 89% male) who completed symptom self-report measures of DSM-5 PTSD and MDD. RESULTS Confirmatory factor analyses indicated an adequate-fitting four-factor DSM-5 PTSD model and two-factor MDD model. Compared to other PTSD factors, the PTSD NACM factor had the strongest relationship with the MDD Affective factor, and the PTSD NACM and Hyperarousal factors had the strongest association with the MDD Somatic factor. Further, the PTSD NACM factor explained the relationship between MDD factors and PTSD symptom severity. More Affective and Somatic depression was related to more NACM symptoms, which in turn were related to increased severity of PTSD. LIMITATIONS Limitations include the reliance on self-report measures and the use of a treatment-seeking, trauma-exposed veteran sample which may not generalize to other populations. CONCLUSIONS Implications concerning the shared somatic complaints and psychological distress in the comorbidity of PTSD and MDD are discussed.

Spiritual struggles and suicide in veterans seeking PTSD treatment.

Objective: Research indicates that trauma can precipitate a loss of faith and struggles in the spiritual domain, leading to increased suicide risk. However, little is known about the specific types of spiritual struggles that may confer risk. This brief report examines the utility of a newly developed measure, the Religious and Spiritual Struggles Scale in gauging suicide risk in veterans. Method: As part of their initial assessment, 52 veterans presenting to an outpatient posttraumatic stress disorder and substance use clinic were administered self-report symptom measures. Results: Multiple regression analyses revealed that divine struggles and struggles with the ultimate meaning were significantly and positively associated with increased suicide risk, even after controlling for relevant demographic (e.g., being male and Caucasian) and psychological variables (e.g., posttraumatic stress disorder symptoms as well as alcohol and substance use symptoms). Conclusions: Results provide preliminary support for use of the Religious and Spiritual Struggles Scale with veterans and highlight the potential utility in assessing for spiritual struggles when assessing suicide risk.

Examining various subthreshold definitions of PTSD using the Clinician Administered PTSD Scale for DSM-5

BACKGROUND The Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5; American Psychiatric Association [APA], 2013) includes Other- and Unspecified- Trauma and Stressor-Related Disorders to capture subthreshold Posttraumatic Stress Disorder (PTSD) symptoms. However, the DSM-5 does not specify the number or type of symptoms needed to assign them. The purpose of the current study was to extend our understanding of subthreshold PTSD by comparing four commonly used definitions adapted to the DSM-5 PTSD criteria in an outpatient treatment-seeking sample. METHODS Veterans (N = 193) presenting to PTSD clinics were assessed using the Clinician Administered PTSD Scale for DSM-5 (CAPS-5). Participants reported a criterion A traumatic event, but did not meet criteria for threshold-PTSD. We hypothesized that the number of veterans captured would be highest when fewer specific criterion sets were required by the subthreshold definition. RESULTS Our hypothesis was upheld in that the more criteria required by the subthreshold PTSD definition, the lower the number of veterans counted within the group. LIMITATIONS The study consisted primarily of trauma treatment-seeking male veterans, with chronic PTSD symptoms. In addition, the sample size was small and was collected as part of routine clinical care. CONCLUSIONS These results support previous contentions around careful decision making when defining what constitutes subthreshold PTSD in research and clinical work. It also points to the need for continued research to better understand the diagnostic and treatment implications of subthreshold PTSD.
