MMPI-2 F scale elevations in adult victims of child sexual abuse

Classification of performance validity and symptom validity using the Trauma Symptom Inventory-2

The Trauma Symptom Inventory-Second Edition (TSI-2) is garnering research interest as a symptom validity test in the evaluation of trauma-related disorders. However, there has been limited empirical validation of its validity scales in clinical and forensic real-world settings. This study evaluated the ability of the TSI-2 Atypical Response (ATR) scale to discriminate response bias in cognitive performance and symptom reporting in a large sample of disability and compensation-seeking claimants. This retrospective chart review included 296 adults with a known history of trauma exposure or claimed trauma-related psychological injury who underwent neuropsychological and/or comprehensive psychological assessment in a private neuropsychology clinic. The discriminability of the ATR scale to classify credible versus non-credible cognitive profiles and symptom reporting were analyzed by AUC-ROCs. Overall, the ATR scale demonstrated poor discriminability of assessment validity based on the Word Memory Test, Victoria Symptom Validity Test, and Minnesota Multiphasic Personality Inventory-2-Restructured Form. The ATR scale had fair discriminatory ability of only one of the over-reporting scales (F-r), with an ROC area of .73, p = .001. However, the test publisher's proposed ATR cut-offs of ≥8 for screening, research, and normal groups, and ≥15 in forensic and clinical settings revealed significant issues with sensitivity and specificity. These results suggest that the TSI-2 should be paired with other established performance validity and symptom validity tests in clinical assessments and not be used as the primary or sole indicator of assessment validity.

The utility of the Structured Inventory of Malingered Symptomatology for distinguishing individuals with Dissociative Identity Disorder (DID) from DID simulators and healthy controls

BACKGROUND

Individuals with dissociative identity disorder (DID) have complex symptoms consistent with severe traumatic reactions. Clinicians and forensic assessors are challenged by distinguishing symptom exaggeration and feigning from genuine symptoms among these individuals. This task may be aided by administering validity measures.

OBJECTIVE

This study aimed to document how individuals with DID score on the Structured Inventory of Malingered Symptomatology (SIMS). The second objective was to compare coached DID simulators and healthy controls to DID patients on the SIMS's total score and subscales. The third objective was to examine the utility rates of the SIMS in distinguishing simulated DID from clinically diagnosed DID.

METHOD

We compared SIMS data gathered from participants from two Dutch sites, one Swiss site and one U.S. site. Sixty-three DID patients were compared to 77 coached DID simulators and 64 healthy controls on the SIMS. A multivariate analysis compared the groups on the SIMS total scores and subscales, and post-hoc Games Howell tests and univariate ANOVAs examined differences between the groups. Utility statistics assessed the accuracy of the SIMS in distinguishing clinical from simulated DID.

RESULTS

DID simulators scored significantly higher than DID individuals and healthy controls on every SIMS subscale as well as the total score. The majority (85.7%) of the individuals with DID scored above the cut-off, which is typically interpreted as indicative of possible symptom exaggeration. DID individuals scored higher than the healthy controls on every subscale except Low Intelligence, even after controlling for dissociation. The subscales and items most frequently endorsed by the DID group are consistent with symptoms associated with complex trauma exposure and dissociative reactions. The SIMS total score had a sensitivity of 96% but an unacceptably low specificity of 14%.

CONCLUSIONS

The findings indicate that the instrument is not accurate in assessing potential symptom exaggeration or feigning in DID.

Psychotic-Like Symptoms and the Temporal Lobe in Trauma-Related Disorders: Diagnosis, Treatment, and Assessment of Potential Malingering

Objective

To overview the phenomenology, etiology, assessment, and treatment of psychotic-like symptoms in trauma-related disorders focusing on the proposed role of temporal lobe dysfunction.

Method

We describe the literature pertaining to (i) psychotic-like symptoms and temporal lobe dysfunction in trauma-related disorders and (ii) psychological testing profiles in trauma-related disorders. We define trauma-related disorders as borderline personality disorder, post-traumatic stress disorder, and the dissociative disorders. Our search terms were dissociative disorders, temporal lobe, trauma, post-traumatic stress disorder, borderline personality disorder, psychosis, and malingering.

Results

Trauma-related psychotic-like symptoms are common and can differ in phenomenology from primary psychotic symptoms. Hallucinations consist of auditory and nonauditory content that may or may not relate to traumatic content. Child voices are highly suggestive of complex dissociative disorders. Critically, not only do these symptoms resemble those seen in temporal lobe epilepsy, but the temporal lobe is implicated in trauma-related disorders, thus providing a plausible neurobiological explanation. Despite such evidence, these symptoms are frequently considered atypical and misdiagnosed. Indeed, common structured psychological assessment tools categorize these symptoms as possible indicators of invalid testing profiles.

Conclusion

Psychotic-like symptoms are common in trauma-related disorders, may be related to temporal lobe dysfunction, and are frequently misinterpreted. This may lead to ineffective treatment and inappropriate determinations of malingering in the forensic system.

The Effect of Child Sexual Abuse on Men: Toward a Male Sensitive Measure

Child sexual abuse (CSA) is a trauma that affects males in substantial numbers, sometimes in ways that are gender-specific (e.g., compromised masculine identity, confusion regarding sexuality). Much of the identification of the male-specific outcomes has been derived from practitioner experience and small qualitative studies. The current study explores gender-specific outcomes and describes the development of a scale to measure the effects of CSA on men. First, qualitative interviews with 20 men who were sexually abused in childhood were thematically analyzed. The emergent themes of sexuality, self-concept, psychological and emotional well-being, and social functioning were used to construct a 30-item instrument which was later completed by 147 men with histories of CSA. The dimensionality of the 30 items was then assessed for suitability as scales using confirmatory factor analysis (CFA). The final instrument, the Male Sexual Abuse Effects Scale (MSAES), combines three subscales: Negative Identity, Guilt and Self-Blame, and Psychological and Emotional Well-Being. Items concerning masculine identity were shown to be valid in the scale. MSAES scores were compared with the General Health Questionnaire-28 (GHQ-28) and found to be significantly correlated. GHQ-28 clinical thresholds were applied to differentiate clinical from nonclinical cases; an independent-samples t test showed that the clinical cases from the GHQ-28 had high scores on the MSAES. The new scale has the potential to help clinicians and researchers identify men who have been severely affected by CSA and who should be of clinical concern.

Assessment of complex dissociative disorder patients and simulated dissociation in forensic contexts

Few assessors receive training in assessing dissociation and complex dissociative disorders (DDs). Potential differential diagnoses include anxiety, mood, psychotic, substance use, and personality disorders, as well as exaggeration and malingering. Individuals with DDs typically elevate on many clinical and validity scales on psychological tests, yet research indicates that they can be distinguished from DD simulators. Becoming informed about the testing profiles of DD individuals and DD simulators can improve the accuracy of differential diagnoses in forensic settings. In this paper, we first review the testing profiles of individuals with complex DDs and contrast them with DD simulators on assessment measures used in forensic contexts, including the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), Personality Assessment Inventory (PAI), and the Structured Inventory of Reported Symptoms (SIRS), as well as dissociation-specific measures such as the Dissociative Experiences Scale (DES) and Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D-R). We then provide recommendations for assessing complex trauma and dissociation through the aforementioned assessments.

Utility of the Trauma Symptom Inventory’s Atypical Response Scale in Detecting Malingered Post-Traumatic Stress Disorder

The authors examined the Trauma Symptom Inventory’s (TSI) ability to discriminate 88 student post-traumatic stress disorder (PTSD) simulators screened for genuine PTSD from 48 clinical PTSD-diagnosed outpatients. Results demonstrated between-group differences on several TSI clinical scales and the Atypical Response (ATR) validity scale. Discriminant function analysis using ATR revealed 75% correct patient classification but only 48% correct simulator classification, with an overall correct classification rate of 59% (positive predictive power [PPP] = .71; negative predictive power [NPP] = .51). Individual ATR cutoff scores did not yield impressive classification results, with the optimal cutoff (T score = 61) correctly classifying only 61% of simulators and patients (PPP = .66, NPP = .54). Although ATR was not developed as a malingered PTSD screen, instead serving as a general validity screen, caution is recommended in its current clinical use for detecting malingered PTSD.

Discriminating Malingered From Genuine Civilian Posttraumatic Stress Disorder

The Infrequency-Posttraumatic Stress Disorder scale (Fptsd), recently created for the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), has demonstrated incremental validity over other MMPI-2 scales in malingered posttraumatic stress disorder (PTSD) detection. Fptsd was developed with combat-exposed PTSD patients, potentially limiting its use with PTSD patients in general. The current study evaluated the MMPI-2’s F, Infrequency-Psychopathology scale (Fp), and Fptsd scales in discriminating genuine civilian PTSD among 41 adult victims of child sexual abuse from a group of 39 students instructed to simulate PTSD. Analyses demonstrated Fptsd’s incremental validity over F but not over Fp. Based on the two studies examining Fptsd, Fptsd may be more appropriate for combat trauma victims, and Fp may be more appropriate for civilian trauma victims.

Extrasensory Perception Experiences and Childhood Trauma: A Rorschach Investigation

This study investigated whether people who report recurrent extrasensory perception (ESP) experiences (telepathy, clairvoyance, and precognition) have suffered more traumatic experiences and traumatic intrusions. Thirty-one nonclinical participants reporting recurrent ESP experiences were compared with a nonclinical sample of 31 individuals who did not report recurrent ESP phenomena. Past traumatic experiences were assessed via a self-report measure of trauma history (Childhood Trauma Questionnaire); traumatic intrusions were assessed via a performance-based personality measure (Rorschach Traumatic Content Index). Participants also completed the Anomalous Experience Inventory, the Minnesota Multiphasic Personality Inventory-2, the Dissociative Experience Scale, and the Revised Paranormal Belief Scale. The ESP group reported higher levels of emotional abuse, sexual abuse, emotional neglect, physical neglect, and traumatic intrusions. The association between ESP experiences and trauma was partly mediated by the effects of dissociation and emotional distress. Implications for health professionals are discussed. Results also showed the reliability of the twofold method of assessment of trauma.

Personality assessment inventory profile and predictors of elevations among dissociative disorder patients

Assessing patients with dissociative disorders (DD) using personality tests is difficult. On the Minnesota Multiphasic Personality Inventory-2 ( J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989 ), DD patients often obtain elevations on multiple clinical scales as well as on validity scales that were thought to indicate exaggeration yet have been shown to be elevated among traumatized individuals, including those with DD. No research has been conducted to determine how DD patients score on the Personality Assessment Inventory (PAI; L. C. Morey, 1991 ), which includes the symptom exaggeration scale Negative Impression (NIM) and the malingering scales Malingering Index (MAL) and Rogers Discriminant Function (RDF). The goals of this study were to document the PAI profile of dissociative identity disorder (DID) and dissociative disorder not otherwise specified (DDNOS) patients and to determine how the validity and Schizophrenia scales are related to other PAI scales as well as dissociation. A total of 42 inpatients with DID or DDNOS were assessed on the PAI as well as the Dissociative Experiences Scale-II. The DID/DDNOS patients were elevated on many PAI scales, including NIM and, to a lesser extent, MAL, but not RDF. Dissociation scores significantly and uniquely predicted NIM scores above and beyond Depression and Borderline Features. In addition, after we controlled for MAL and RDF, dissociation was positively associated with NIM. In contrast, after we controlled for the other 2 scales, dissociation was not related to MAL and was negatively related to RDF, indicating that RDF and, to a lesser extent, MAL are better correlates of feigning in DD patients than NIM.

The prevalence of child sexual abuse in community and student samples: a meta-analysis

BACKGROUND

Studies conducted internationally confirm that child sexual abuse is a much more widespread problem than previously thought, with even the lowest prevalence rates including a large number of victims that need to be taken into account.

OBJECTIVE

To carry out a meta-analysis of the prevalence of child sexual abuse in order to establish an overall international figure.

METHODS

Studies were retrieved from various electronic databases. The measure of interest was the prevalence of abuse reported in each article, these values being combined via a random effects model. A detailed analysis was conducted of the effects of various moderator variables.

RESULTS

Sixty-five articles covering 22 countries were included. The analysis showed that 7.9% of men (7.4% without outliers) and 19.7% of women (19.2% without outliers) had suffered some form of sexual abuse prior to the age of eighteen.

CONCLUSIONS

The results of the present meta-analysis indicate that child sexual abuse is a serious problem in the countries analysed.

The somatically preoccupied patient in primary care: use of attachment theory to strengthen physician-patient relationships

Background

Individuals with somatic preoccupation constitute a substantial number of primary care patients. Somatically preoccupied patients are challenging to primary care physicians for several reasons including patient complaints consuming a great deal of physician time, expense to diagnose and treat and strain on the physician-patient relationship. This paper examines and discusses how disruptions in early attachment relationships such as often occurs when a female is a victim of child sexual abuse may result in somatic preoccupation in adulthood.

Treatment utilizing attachment theory

Attachment theory provides a useful framework for primary care physicians to conceptualize somatic preoccupation. Utilization and containment techniques grounded in an understanding of attachment dynamics aid the physician in developing a sound physician-patient relationship. Successfully engaging the patient in treatment prevents misunderstandings that frequently derail medical care for somatically preoccupied patients.

Clinical profile differences between PTSD-diagnosed military veterans and crime victims

Few studies have conducted symptom comparisons across different trauma-exposed populations. Evidence linking different types of trauma to variations in clinical presentation would have potential implications for the assessment and treatment of trauma-related psychopathology. The current study evaluated whether military veterans (n = 187) and civilian crime victims (n = 47) diagnosed with posttraumatic stress disorder differ in their self-reported posttraumatic symptoms as measured by the Trauma Symptom Inventory. A multivariate profile analysis revealed that military-related trauma is associated with more severe posttraumatic symptoms than criminal victimization and suggested that these 2 types of trauma have statistically distinct symptom profiles. Some potential implications of these findings and considerations for future research are discussed.

ANALYSIS OF DEMOGRAPHIC FACTORS ON F SCORES AND EVALUATION OF NEW CONFIGURATIONS OF F SCALES

We analyzed the influence of demographic factors on scores of the Infrequency scale of the MMPI (Archer, Gordon, & Kirchner, 1987) administered to male youth in China. The demographic factors, acting as influencing factors of F scores, could be ignored. New configurations of infrequency scales were presented and discussed, which indicated that it was appropriate to choose a 20% item endorsement percentage (IEP) of the Chinese male youth as the criterion for item selection.

Symptom overreporting and recovered memories of childhood sexual abuse

The authenticity of recovered memories is a much debated issue. Surprisingly, no study has systematically looked at symptom overreporting in people claiming recovered memories of childhood sexual abuse (CSA). In a first sample we administered the Structured Inventory of Malingered Symptomatology (SIMS) to individuals who said they had recovered CSA memories (n=66), individuals who said their CSA had always been accessible (continuous CSA memory group; n=119), and controls who said they had no CSA experiences (n=83). In a second sample individuals reporting recovered (n=45) or continuous (n=45) CSA memories completed the Morel Emotional Numbing Test (MENT). Our aim was to compare these groups with regard to their tendency to overreport symptoms. The results indicate that people with recovered memories do not score higher on the SIMS and the MENT than other CSA survivors suggesting that symptom overreporting is not typical for people reporting recovered memories.
