Absenteeism and productivity among mental health employees.

We examined archival data to test the hypothesis that absenteeism is inversely related to work productivity among mental health employees at a Veterans Affairs Medical Center outpatient clinic. Results provided partial support for this hypothesis in that there was an inverse correlation between one measure of productivity and the percentage of sick and family care leave taken on Mondays and Fridays (r=.54). No significant relationship between work productivity and total sick and/or family care leave was found, although there was a trend in that direction (r=.34). These data suggest that mental health clinicians who use high levels of sick and/or family care leave are not necessarily unproductive workers. However, high percentages of absenteeism on Mondays and Fridays may represent a red flag for identifying under-performing clinicians. Examination of absenteeism patterns may prove useful for administrators. Management policy strategies to reduce absenteeism are suggested.

Trauma exposure, resilience, social support, and PTSD construct validity among former prisoners of war.

BACKGROUND: The aim of this study was to investigate predictors of persistent symptoms of posttraumatic stress disorder (PTSD) and to examine the construct validity of PTSD in a national sample of 270 World War II and Korean Conflict prisoners of war (POWs). METHOD: POWs were interviewed at two points in time (1965 and 1990). Predictors included PTSD symptomatology measured in 1965 by items from the Cornell Medical Index (CMI), severity of captivity trauma, resilience factors, and post-trauma social support. The criterion, symptomatology in the early 1990s, was evaluated with the PTSD module of the Structured Clinical Interview for DSM (SCID). RESULTS: The CMI provided only partial coverage of PTSD criteria and appeared to provide only a general index of distress. Clustering of SCID items in two-dimensional space via multidimensional scaling analysis offers some construct validation for the DSM's differentiation of PTSD symptoms into criterion groups, although there was not a perfect match. Trauma severity is best related to PTSD symptomatology experienced in 1990, mitigated in part by greater education level and age at the time of trauma exposure. Surprisingly, 1965 distress added only a modest amount to the prediction of current distress, while post-trauma social support added none. CONCLUSIONS: These findings support previous work showing the severe psychological sequelae of POW status 40-50 years after captivity, and indicate that trauma severity during captivity is the best predictor of current PTSD symptomatology. Results also add to our understanding of the conceptual differentiation of PTSD symptoms into separate and distinct symptom clusters.

Apparent symptom overreporting in combat veterans evaluated for PTSD.

Psychometric studies have consistently shown that combat veterans evaluated for posttraumatic stress disorder (PTSD) appear to overreport psychopathology as exhibited by (a) extreme and diffuse levels of psychopathology across instruments measuring different domains of mental illness, and (b) extreme elevations on the validity scale of the MMPI-MMPI-2, in a "fake-bad" direction. The phenomenon of this ubiquitous presentational style is not well understood at present. In this review we describe and delineate the assessment problem posed by this apparent symptom overreporting, and we review the literature regarding several potential explanatory factors. Finally, we address conceptual and practical issues relevant to reaching a better understanding of the phenomenon, and ultimately the clinical syndrome of combat-related PTSD, in both research and clinical settings.

Clinical presentations of posttraumatic stress disorder across trauma populations: a comparison of MMPI-2 profiles of combat veterans and adult survivors of child sexual abuse.

This investigation examined differences in symptom patterns of two different trauma samples using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). MMPI-2s of 122 male combat veterans seeking outpatient treatment for combat-related PTSD were compared with those of 64 PTSD-diagnosed adults seeking outpatient treatment for the effects of child sexual abuse (CSA). We examined variables related to degree of health concerns, depression, somatization, anger and hostility, masculine-feminine traits, paranoid ideation, anxiety, difficulties thinking and concentrating, elevated mood, and social introversion, as well as test-taking attitude. MANOVAs revealed between-group differences on several variables. However, when analyses controlled for the effect of age, nearly all differences disappeared; the only remaining difference was in a scale measuring anger. Thus, it appears CSA survivors and combat veterans are much more similar than different in their clinical presentation on the MMPI-2. Conceptual issues in the assessment of PTSD are discussed.

Procedural and methodological issues in telepsychiatry research and program development.

OBJECTIVE: The authors reviewed the literature related to telepsychiatry-applications of videoconferencing technology for mental health care-which offers hope for an affordable means of solving long-standing workforce problems, particularly in geographical areas where specialist providers are not readily available. METHODS: To conduct a comprehensive review of the telepsychiatry literature, the authors searched the MEDLINE database (1970 to February 2000), using the keywords telepsychiatry, telemedicine, and videoconferencing. Studies were selected that included the use of videoconferencing technology for the provision of any form of mental health care services. RESULTS AND CONCLUSIONS: Psychiatric interviews conducted by telepsychiatry appear to be generally reliable, and patients and clinicians generally report high levels of satisfaction with telepsychiatry. A significant limitation of the literature is the lack of empirical research on telepsychiatry, especially cost analyses and clinical outcome studies. The authors outline a research agenda addressing the procedural and methodological issues that should shape future research: study design, outcome measurement, consideration of patient characteristics, and program design.

Cross-validation of the MMPI-2 in detecting malingered posttraumatic stress disorder.

We attempted to cross-validate findings from a previous study (Elhai, Gold, Sellers, & Dorfman, in press) using a clinical sample of combat-related war veterans to distinguish genuine from malingered posttraumatic stress disorder (PTSD) on the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). The MMPI-2 scores of 124 male combat war veterans at the PTSD outpatient treatment program of a Veterans Affairs Medical Center were compared with those of 84 adult college students instructed and trained to malinger PTSD. MMPI-2 overreporting variables examined were F, F-Fb, F-K, F(p), Ds2, O-S, OT, and FBS. A stepwise discriminant analysis identified F. F-Fb, F-K, Ds2, O-S, and OT as the best malingering predictors. A predictive discriminant analysis yielded good hit rates for the model with impressive cross-validation results. We assessed cutting scores for the predictors of the model. We discuss clinical implications for using the MMPI-2 to distinguish malingered PTSD from combat-related PTSD.

Panic disorder in primary care: patients' attributions of illness causes and willingness to accept psychiatric treatment.

OBJECTIVE: This study assessed the causes that primary care patients with panic disorder (PD) attribute to their panic symptoms, and their acceptance of various psychiatric treatment options. METHODS: In a cross-sectional assessment of 306 patients treated at two primary care clinics, 42 met criteria for DSM-IV PD in the past year. The authors classified these 42 PD-positive patients to one of two groups: those receiving both primary and specialty mental health care (PC+MH; n = 19) and those receiving only primary care (PC-only; n = 23). Patients rated the probability of four possible causes of their panic symptoms, and level of acceptability of three psychiatric and two medical treatments for PD. To place primary care patients' ratings into a broader context, a third contrast group of PD-positive patients, recruited from clinical trials of investigational PD pharmacotherapies (n = 31), also rated causes and treatment acceptability. RESULTS: Participants of the three treatment groups attributed psychiatric causes for their panic symptoms in approximately the same proportion (78 percent to 90 percent; p = ns). PC-only participants attributed medical causes for panic symptoms more frequently than PC+MH and PD Clinical Trials participants (48 percent vs. 5 percent and 32 percent; p = .01). Remarkably, the great majority of patients across all groups expressed willingness to see psychiatrists (84 percent to 94 percent) and psychotherapists (95 percent to 100 percent), and to take psychotropic medications (87 percent to 100 percent). CONCLUSIONS: In this study most patients attributed a psychiatric cause for panic symptoms and communicated strong acceptance of psychiatric treatment. Thus, we recommend that primary care clinicians more assertively inform their patients of PD diagnoses and recommend psychiatric treatments with less fear about stigmatizing and alienating them.

Compensation-seeking and extreme exaggeration of psychopathology among combat veterans evaluated for posttraumatic stress disorder.

We extended the work of Smith and Frueh (1996) by evaluating whether combat veterans classified as "extreme exaggerators" were more likely to be compensation-seeking, and to report greater levels of psychopathology across self-report instruments than "nonexaggerators." Of 119 veterans who completed the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) at an outpatient posttraumatic stress disorder (PTSD) clinic, 26 (22%) and 17 (14%) were identified as extreme exaggerators using two MMPI-2 validity indicators with stringent cutoffs (F-K > or = 22; F(p) > or = 8). These veterans were much more likely to be compensation seeking and scored much higher on self-report measures of various psychological symptoms than nonexaggerators, despite having lower rates of PTSD diagnoses and similar rates of other comorbid diagnoses. Findings suggest that the validity indices of the MMPI-2 can play a critical role, as a screening instrument, in identifying veterans who may be exaggerating their psychopathology to gain disability compensation.

Plasma dopamine beta-hydroxylase activity in psychotic and non-psychotic post-traumatic stress disorder.

Recognition and treatment of comorbid chronic psychotic symptoms in post-traumatic stress disorder (PTSD) has become of increasing clinical interest. Altered dopamine beta-hydroxylase (DBH) activity has been reported in mood disorders. Plasma DBH is reduced in major depression with psychosis and elevated in bipolar disorder with psychosis compared with their respective non-psychotic diagnostic groups. DBH is likely a trait marker with interindividual variations secondary to genetic polymorphism. We therefore evaluated DBH activity in PTSD patients with and without psychotic features and compared these groups with age- and gender-matched control subjects. Vietnam combat veterans with PTSD (n = 19) (including patients with and without psychotic features) and normal control subjects (n = 22) had plasma DBH enzyme activity assayed photometrically. DBH was significantly higher in patients with PTSD with psychotic features than in patients without psychotic features (80.6 +/- 13.4 vs. 42.1 +/- 7.3 mM/min, P < 0.01) and was also higher than normal control subjects (46.12 +/- 4.93, P < 0.01). Plasma DBH activity may differentiate psychotic and non-psychotic subtypes of PTSD. The observed changes are, interestingly, opposite to those seen in psychotic depression but comparable to psychotic bipolar disorder. Since DBH is a genetic marker, this may reflect individual vulnerabilities to develop psychosis in the context of trauma.

Symptom overreporting in combat veterans evaluated for PTSD: differentiation on the basis of compensation seeking status.

We examined the role of compensation-seeking status on response patterns to self-report inventories of acute psychopathology and psychological distress in a group of 165 combat veterans evaluated for posttraumatic stress disorder (PTSD) at a Department of Veteran Affairs (VA) Medical Center. Veterans completed the Minnesota Multiphasic Personality Inventory-Revised, Beck Depression Inventory, Mississippi Scale for Combat-Related PTSD, a fixed-response format version of the Dissociative Experiences Scale, and Impact of Events Scale as part of a standard assessment battery. Results showed that compensation-seeking veterans endorsed dramatically higher levels of psychopathology across measures and produced sharply elevated "fake-bad" validity indices as compared to non-compensation-seeking veterans. Differences between the two groups on most scales and indices exceeded effect sizes of 1.0, even when effects of income, global assessment of functioning, and clinician-rated severity of PTSD were controlled for. It is suggested that the availability of VA disability compensation for combat-related PTSD impedes accurate initial assessment of veterans presenting for treatment and may impair estimation of long-term therapeutic outcome in this population.

A racial comparison of combat veterans evaluated for PTSD.

This study attempted to replicate the work of Frueh, Smith, and Libet (1996), which showed racial differences on psychological measures of dissociation/thought disturbance and the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) F-K index in combat veterans evaluated for posttraumatic stress disorder (PTSD). Veterans completed the Beck Depression Inventory, Mississippi Scale for Combat-Related PTSD, a fixed-response format version of the Dissociative Experiences Scale (DES-FRF), and MMPI-2 prior to treatment at a Veterans Affairs hospital outpatient PTSD clinic. Contrary to expectation, significant racial differences on the DES-FRF, MMPI-2 validity scales, and MMPI-2 Scales 6 and 8 were not found. Consistent with the previous study, no racial differences on measures of anxiety, depression, or PTSD symptomatology were found; nor were there racial differences on clinician ratings of global assessment of functioning or on most categories of psychiatric diagnoses. This suggests that Black and White combat veterans evaluated for PTSD do not differ with regard to reported manifestation or severity of psychopathology.
