Identifying Subtypes of Women Survivors of Childhood Sexual Abuse: An MMPI-2 Cluster Analysis

This paper investigated subtypes of women childhood sexual abuse (CSA) survivors through a cluster analysis of their Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical and validity scales. Participants were 117 women in outpatient treatment for CSA aftereffects at a university-affiliated community mental health center. Three well-fitting MMPI-2 cluster solutions were evaluated with discriminant analyses and MANOVAs; a 5-cluster solution was deemed optimal. Follow-up analyses demonstrated significant between-cluster differences on the Impact of Event Scale, Beck Depression Inventory, Dissociative Experiences Scale, and nearly all Symptom Checklist-90-Revised subscales. No differences emerged when comparing clusters on the Family Environment Scale and their CSA characteristics. Implications were considered for research and clinical practice, using the MMPI-2 with CSA survivors.     

Post-traumatic stress disorder and the MMPI-2

This study compared the MMPI-2 profiles of 27 veterans diagnosed with post-traumatic stress disorder with a non-PTSD comparison group of 27 veteran patients receiving inpatient treatment for other mental disorders. Three multivariate analyses of variance were conducted comparing the two groups on the 10 traditional clinical scales, the 12 supplemental scales and the 15 new content scales on the MMPI-2. The PTSD group obtained a mean profile with peak elevations on the F validity scale and on clinical Scales 2 (D) and 8 (Sc). The multivariate analysis of variance comparing the PTSD and non-PTSD groups across the 10 traditional clinical scales was not significant. The multivariate analyses of variance comparing the two groups on the 12 supplemental scales and the 15 content scales were significant. Significant univariate supplemental scale differences were found on the Keane PTSD scale (PK) and the Post-Traumatic Stress Disorder (PS) scale with the PTSD group scoring higher on PK and PS. Significant univariate content scale differences were found for the Anger (ANG) scale with the PTSD group scoring higher. A cut-off score of 28 on the PK scale correctly classified 76% of the overall sample, 67% of the PTSD group and 85% of the non-PTSD-comparison group.     

Post-traumatic stress disorder in child sexual abuse survivors: A literature review

Research to date has failed to identify a unique syndrome describing the sequelae of child sexual abuse (CSA). Recently, however, some researchers have suggested Post-Traumatic Stress Disorder as the diagnosis which best fits the syndrome commonly seen in CSA survivors. Research examining the consequences of CSA in terms of the applicability of a PTSD diagnosis is reviewed. Additionally, based on findings of significant relationships between PTSD and traumatic exposure in other trauma groups, this review also examines studies which have investigated relationships between exposure and symptom development among CSA survivors. Finally, conclusions regarding the applicability of PTSD to CSA survivors and suggestions for future research are offered.This article was accepted for publication under the Editorship of Charles R.

Examining comorbidity and posttraumatic stress disorder in a vietnam veteran population using the MMPI-2

Examined the discriminant validity of the MMPI-2 in assessing comorbidity in a posttraumatic stress disorder (PTSD) Vietnam veteran population. The Structured Clinical Interview for the DSM-III-R (SCID) was used to diagnose veterans and to classify them into four groups: PTSD Only, PTSD with mood disorders, PTSD with other anxiety disorders, and PTSD with mood and anxiety disorders. All groups had clinical elevations on scales F, 1, 2, 3, 4, 6, 7, 8, 0, PK, and PS, with peak elevations on scales 8, 7, and 2. The PTSD Only group's MMPI-2 scores were not significantly lower than other groups' scores. The PTSD+Mood/Anxiety group was significantly more elevated on scales 2 and 7 than the PTSD Only and PTSD+Anxiety group but did not otherwise show significantly higher scale elevations than other groups. No significant differences existed between groups on scales F, L, K, PK, and PS. Implications of these results for PTSD and the current diagnostic system are explored.     

MMPI, MMPI-2 and PTSD: Overview of Scores, Scales, and Profiles

A number of issues should be considered when applying profile interpretations and subscales derived from the original MMPI. These issues and the overall utility of the MMPI-2 for posttraumatic stress disorder (PTSD) evaluations are summarized. The Keane PTSD scale is found to be an effective tool for differential diagnosis when a cut-off score of 28 is used. The Schlenger PTSD scale warrants additional study. Various MMPI-2 validity scales are useful in detecting malingering, but concurrence regarding cut-off scores is lacking. The 2-8/8-2 MMPI PTSD profile does not emerge as consistently on the MMPI-2 as it did on the MMPI, due to the frequent elevation of scale 7 on the MMPI-2.     

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

The present study assessed whether the Minnesota Multiphasic Personality Inventory—2 (MMPI-2) F scale elevations may reflect genuine trauma-related distress and/or psychopathology, rather than malingering, in a clinical sample of adult child sexual abuse (CSA) victims. Eighty-eight women seeking outpatient treatment for CSA after-effects participated. Self-report measures of dissociation, posttraumatic stress, depression, and family environment individually correlated significantly with F, and collectively accounted for 40% of its variance. Dissociation was the strongest predictor. Findings suggest that high F elevations may reflect genuine problem areas often found among CSA victims, rather than symptom overreporting.     

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.     

Revictimization and Interpersonal Resource Loss Predicts PTSD Among Women in Substance-Use Treatment

Child physical abuse (CPA) and child sexual abuse (CSA) were hypothesized to be associated with revictimization and interpersonal resource loss in adulthood. These adulthood experiences were, in turn, hypothesized to increase risk for current posttraumatic stress disorder (PTSD). High-risk women were recruited from an innercity drug and alcohol treatment center (N = 105). Interpersonal resource losses, partner-produced physical assault, adulthood rape, CPA, and CSA had direct effects on PTSD. CPA and CSA also had indirect effects on PTSD through rape, which, in turn, predicted PTSD. Results suggest that the traumatic origins of current PTSD among substance-using women are multifaceted and support the importance of considering interpersonal coping resources in evaluating and treating female substance users.     

Dysfunctional Cognitions and Adult Psychological Functioning in Child Sexual Abuse Survivors

Two studies explored the relationship between cognitions and long-term symptoms in adult child sexual abuse (CSA) survivors. In Study 1, an American sample of 43 survivors completed questionnaires assessing attributional style and dysfunctional beliefs in cognitive themes affected by victimization, as well as measures of posttraumatic symptoms. Survivors' attributions of negative events were more internal, stable, and global than those of 29 comparison subjects without a history of CSA. However, only the globality scale was significantly related with severity of long-term symptoms. High correlations between dysfunctional beliefs concerning safety, trust, esteem, or intimacy, and posttrauma symptoms were found. The latter finding was replicated in Study 2 with a German sample of 35 CSA survivors, even when controlling for frequency of abuse.     

Symptom Exaggeration and Compensation Seeking Among Combat Veterans with Posttraumatic Stress Disorder

Combat veterans seeking treatment for posttraumatic stress disorder (PTSD) tend to report high levels of psychopathology on self-report instruments. The purpose of the current archival study was to replicate research on the relationships among symptom exaggeration, attempts to obtain compensation, and treatment outcome on the Beck Depression Inventory, the Mississippi Scale for Combat-Related PTSD, and selected MMPI-2 and MCMI-II subscales. Results indicated that symptom exaggeration as defined by an MMPI-2 F-K index over 13 was related to higher scores on all scales examined. Compensation seeking was not related to assessment scores or exaggeration. Neither compensation seeking nor exaggeration was related to treatment outcome. Limitations of the study and implications for future research are discussed.     

Psychiatric and Physical Sequelae of Childhood Physical and Sexual Abuse and Forced Sexual Trauma Among Individuals With Serious Mental Illness

Trauma and posttraumatic stress disorder (PTSD) frequently co‐occur with serious mental illness, yet the unique mental and physical health influences of childhood physical abuse (CPA), childhood sexual abuse (CSA), and forced sexual trauma on individuals with serious mental illness remain unevaluated. The present study of 172 individuals with serious mental illness investigated the adverse effects of CPA, CSA, and forced sexual trauma on severity of PTSD and depression, and overall mental and physical health functioning. Data analysis consisted of chi‐square tests, independent t tests, bivariate odds ratios, and linear regressions. Prevalence of CPA (44.8%), CSA (29.1%), and forced sexual trauma (33.1%) were elevated, and nearly one third of participants (31.4%) reported clinical PTSD. Participants exposed to CSA or forced sexual trauma evidenced bivariate ORs ranging from 4.13 to 7.02 for PTSD, 2.44 to 2.50 for major depression, and 2.14 to 2.31 for serious physical illness/disability. Sexual trauma exposure associated with heightened PTSD and depression, and reduced mental and physical health functioning, with CSA uniquely predicting PTSD, depression, and physical health difficulties. CPA less significantly affected these clinical domains. Sexual traumas have profound negative effects on mental and physical health outcomes among individuals with serious mental illness; increased screening and treatment of sexual traumas is needed.     

An Affect-Management Group for Women with Posttraumatic Stress Disorder and Histories of Childhood Sexual Abuse

Systematic research on effective treatment for survivors of childhood sexual abuse with posttraumatic stress disorder (PTSD) is virtually non-existent. The aim of the present study was to compare the effectiveness of an affect-management treatment (AM) group to a wait list control condition for female survivors of childhood sexual abuse with PTSD. Forty-eight female survivors of childhood sexual abuse with PTSD were randomly assigned to either a 15-week affect-management treatment group or to a wait list control condition. All subjects received individual psychotherapy and pharmacotherapy for the duration of the study, and for at least 1-month prior to the study. Controlling for pretreatment scores, subjects who completed the affect-management treatment group (n = 17) reported significantly fewer posttreatment symptoms of PTSD and dissociation than subjects in the wait list control condition (n = 16). Our findings suggest that an affect-management group treatment is beneficial as an adjunct to individual psychotherapy and pharmacotherapy for survivors of childhood sexual abuse with PTSD.     

MMPI Scales for Diagnosing Acute and Chronic PTSD in Civilians

To develop new Minnesota Multiphasic Personality Inventory (MMPI) scales for diagnosing acute and chronic posttraumatic stress disorder (PTSD), 237 civilians with PTSD or panic disorder (controls) completed the MMPI-R. All 399 items were submitted to chi-square analysis to select those differentiating acute or chronic PTSD from controls. The analyses yielded an MMPI Acute PTSD scale (32 items) and a MMPI Chronic PTSD scale (41 items). Discriminating between acute PTSD and controls, the MMPI Acute PTSD scale had a hit rate of 83% and the MMPI Chronic PTSD scale produced a hit rate of 75% to 80%. Cross-validation produced similar hit rates. These scales scores were not substantially influenced by gender or types of traumatic events, and only the MMPI Acute PTSD scale seemed to not be sensitive to co-morbidity.     

The Indirect Effect of Posttraumatic Stress Disorder Symptoms on Current Alcohol Use Through Negative Cognitions in Sexual Minority Men

Self‐medication theory posits that some trauma survivors use alcohol to cope with posttraumatic stress disorder (PTSD) symptoms, but the role of negative posttraumatic cognitions in this relationship is not well defined. We examined associations among PTSD symptoms, posttraumatic cognitions, and alcohol intoxication frequency in 290 men who have sex with men (MSM), who reported a history of childhood sexual abuse (CSA). Using a bootstrap approach, we examined the indirect effects of PTSD symptoms on alcohol intoxication frequency through posttraumatic cognitions regarding the self, world, and self‐blame. In separate regression models, higher levels of PTSD symptoms and posttraumatic cognitions were each associated with more frequent intoxication, accounting for 2.6% and 5.2% of the variance above demographics, respectively. When examined simultaneously, posttraumatic cognitions remained significantly correlated with intoxication frequency whereas PTSD symptoms did not. Men reporting elevated posttraumatic cognitions faced increased odds for current alcohol dependence, odds ratio (OR) = 2.19, 95% CI [1.13, 4.22], compared with men reporting low posttraumatic cognitions, independent of current PTSD diagnosis. A higher level of PTSD symptom severity was indirectly associated with more frequent alcohol intoxication through cognitions about the self and world; the indirect to total effect ratios were 0.74 and 0.35, respectively. Negative posttraumatic cognitions pertaining to individuals’ self‐perceptions and appraisals of the world as dangerous may play a role in self‐medication with alcohol among MSM with a history of CSA. Interventions targeting these cognitions may offer potential for reducing alcohol misuse in this population, with possible broader implications for HIV‐infection risk.     

MMPI-2 Scores in the Outcome Prediction of Gastric Bypass Surgery

Background: A psychological assessment is critical for morbidly obese patients seeking Roux-en-Y gastric bypass (RYGBP) surgery. The Minnesota Multiphasic Personality Inventory (MMPI) has been widely used in past psychological studies of bariatric surgery patients, but, to date, there is no published research on the more recent version of the MMPI, the Minnesota Multiphasic Personality Inventory-2 (MMPI2), and its relation to RYGBP outcome.This investigation was designed to evaluate the predictive validity of the MMPI-2 with respect to outcome of RYGBP for morbid obesity. Methods: The research involved a retrospective analysis of MMPI-2 scores of 2 groups of patients 1 year following RYGBP: 1) those who lost ≥ 50% of their excess weight and 2) those who lost <50% of their excess weight. Subjects were 52 morbidly obese patients (mean age 44 years, mean BMI 56 kg/m2).The measurement of psychological variables consisted of the MMPI-2 scores of 3 validity scales, 10 clinical scales, and 3 Content Scales, and BMI. Results: Those who lost <50% excess weight scored significantly higher than those who lost >50% excess weight on the F,Hysteria, Paranoia, and Health Concerns scales of the MMPI-2, and significantly lower on the Masculinity-femininity scale. Stepwise regression analysis found that a combination of the Health Concerns and Masculinity-femininity scales was the most accurate predictor model for 1-year post-surgery weight loss. Conclusion: A standard personality measure, the MMPI-2, appears to be associated with weight loss outcome 1 year after RYGBP. Psychological traits such as anxiety and excessive health concerns are likely to influence bariatric surgical outcome.     

Compensation seeking status and psychometric assessment of combat veterans seeking treatment for PTSD

Examined differences between compensation seeking (CS) veterans and noncompensation seeking (NCS) veterans on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and other psychological measures in 142 combat veterans evaluated for posttraumatic stress disorder (PTSD) at an outpatient Veterans Affairs (VA) hospital PTSD clinic. Patients were grouped on the basis of their compensation seeking status, with 69% classified as CS for PTSD. The CS veterans achieved significantly more pathological scores across a wide range of psychological inventories and MMPI-2 validity indices, although they did not differ in frequency of PTSD diagnoses from NCS veterans. Implications of these findings are discussed, and clinicians are advised to be aware of the compensation seeking status of combat-veterans being evaluated for PTSD.     

The utility of the SCL-90-R for the diagnosis of war-zone related posttraumatic stress disorder

A scale for assessing war-zone-related posttraumatic stress disorder (WZ-PTSD scale) was derived from the Symptom Checklist-90-R by identifying items that best discriminated Vietnam theater veterans with and without PTSD (N= 202). The 25-item WZ-PTSD scale had excellent internal consistency, and signal detection analyses revealed that its diagnostic utility was comparable to or exceeded that of several established PTSD scales and measures of global distress. In a cross-validation sample (N=99), the diagnostic utility of the WZ-PTSD scale was stable, whereas other PTSD scales performed more poorly. The WZ-PTSD scale appears to be a valuable new measure of PTSD that can be particularly useful in archival data sets or in any situation where other PTSD measures are not available.     

Hippocampal Volume and Memory Performance in a Community-Based Sample of Women with Posttraumatic Stress Disorder Secondary to Child Abuse

Childhood abuse is linked to posttraumatic stress disorder (PTSD), which follows abuse survivors into adulthood. This study identified the neuropsychological and neuromorphological sequelae of PTSD among prepubescently abused women. Right-handed women aged 20-40 years were placed into PTSD and abuse, abuse only, and normal control groups (n = 17 per group). Participants were screened for trauma history and psychiatric symptoms, demographically matched, and given neuropsychological tests and a magnetic resonance scan of their brain. Women with PTSD did not express significant deficits in memory performance or hippocampal volume when compared with the abuse and normal control groups.     

Externalizing and Internalizing Subtypes of Posttraumatic Psychopathology and Anger Expression

Subtypes of posttraumatic psychopathology were replicated and extended in 254 female veterans with posttraumatic stress disorder (PTSD). Cluster analyses on Minnesota Multiphasic Personality Inventory‐2 and Personality Psychopathology Five scales (Harkness, McNulty, & Ben‐Porath, 1995 ) yielded internalizing and externalizing psychopathology dimensions, with a third low psychopathology group (simple PTSD). Externalizers were higher than the internalizers and the simple PTSD groups on the antisocial, substance, and aggression scales; internalizers were higher on depression and anxiety scales. Further validation included an independent measure of psychopathology to examine anger (Buss‐Durkee Hostility Inventory, [BDHI]; Buss & Durkee, 1957 ). Externalizers were higher on extreme behavioral anger scales (assault and verbal hostility); and externalizers and internalizers were higher than the simple PTSD subjects on other anger scales. Positive correlations between the BDHI scales and the PTSD symptom of “irritability and anger outbursts” were found across scales in the total sample (range: r = .19–.36), on the assault scale in externalizers (r = .59), and the verbal hostility scale in both internalizers (r = .30) and simple PTSD (r = .37) groups, suggesting the broad utility of the symptom in the diagnosis. The results demonstrate the generalizability of the internalizing/externalizing typology to the female veteran population and highlight clinically relevant distinctions in anger expression within PTSD.
