Heterosexual Male Perpetrators of Childhood Sexual Abuse: A Preliminary Neuropsychiatric Model

This paper presents data from a series of prelimary neuropsychiatric studies, including neuropsychological, personality, sexual history, plethysmographic and neuroimaging investigations, on a sample of 22 male, heterosexual, nonexclusive pedophiles and 24 demographically similar healthy controls. A psychobiological model of pedophilia is proposed, positing that early childhood sexual abuse leads to neurodevelopmental abnormalities in the temporal regions mediating sexual arousal and erotic discrimination and the frontal regions mediating the cognitive aspects of sexual desire and behavioral inhibition. In this way, pedophiles develop deviant pedophilic arousal. Subsequently, if there is comorbid personality pathology, specifically sociopathy and cognitive distortions, there will be failure to inhibit pedophilic behavior.

Clinical features of pedophilia and implications for treatment

The authors discuss the diagnostic criteria for pedophilia and review the literature on its clinical features, including data on prevalence, gender, age of onset, number of victims, frequency and type of acts, violence, impulsivity, and insight. Findings concerning the characteristics of victims (e.g., sex, age, relationship to the pedophile) and research on pedophilic subtypes—exclusive versus nonexclusive; incestuous versus nonincestuous; heterosexual, homosexual, or bisexual—are reviewed. Studies have shown that pedophiles may share many psychiatric features beyond deviant sexual desire, including high rates of comorbid axis I disorders (affective disorders, substance use disorders, impulse control disorders, other paraphilias) as well as severe axis II psychopathology (especially antisocial and Cluster C personality disorders). The authors present several possible etiological models for pedophilia and conclude that further research is needed concerning the etiological role of a childhood history of sexual abuse as well as the underlying neurobiology of deviant sexual arousal and decreased erotic differentiation. Finally, findings concerning pharmacological and cognitive-behavioral treatments for pedophilia are briefly reviewed. Recidivism, drop-out, and noncompliance are significant problems in the treatment of pedophilia. The authors review predictors of treatment outcome and conclude that pedophilia is extremely difficult to treat and that effective treatment needs to be intensive, long-term, and comprehensive, possibly with lifetime follow-up.

Relationship between drug company funding and outcomes of clinical psychiatric research.

BACKGROUND Pharmaceutical industry funding of psychiatric research has increased significantly in recent decades, raising the question of a relationship between pharmaceutical company funding of clinical psychiatric studies and the outcomes of those studies. This study examines this relationship. METHOD Abstracts of articles from 1992 and 2002 in four peer-reviewed psychiatric journals were examined. Drug outcomes (n=542) for clinical studies were evaluated and then compared across sponsorship source. Outcome raters were blind to source of sponsorship. The percentage of these studies sponsored by drug companies in 2002 v. 1992 was also compared. In a secondary analysis, the contribution of a series of potentially mediating variables to the relationship between sponsorship source and study outcome was assessed via logistic regression. RESULTS The percentage of studies sponsored by drug companies increased from 25% in 1992 to 57% in 2002. Favorable outcomes were significantly more common in studies sponsored by the drug manufacturer (78%) than in studies without industry sponsorship (48%) or sponsored by a competitor (28%). These relationships remained after controlling for the effects of journal, year, drug studied, time since FDA drug approval, diagnosis, sample size, and selected study design variables. CONCLUSIONS These data indicate an association between pharmaceutical industry funding of clinical studies and positive outcomes of those studies. Further research is needed to elucidate the mechanisms underlying this relationship.

Are there differential relationships between different types of childhood maltreatment and different types of adult personality pathology

While considerable data support the relationship between childhood trauma and adult personality pathology in general, there is little research investigating the specific relationships between different types of childhood maltreatment and adult personality disorders. The present study tested a model incorporating five a priori hypotheses regarding the association between distinct forms of childhood maltreatment and personality pathology in 231 psychiatric patients using multiple self-report measures (Personality Diagnostic Questionnaire-4th Edition, Child Trauma Questionnaire, Conflict in Tactics Scale Parent-Child Child-Adult, and Multidimensional Neglectful Behavior Scale). Step-wise linear regressions supported three out of five hypotheses, suggesting independent relationships between: physical abuse and antisocial personality disorder traits; emotional abuse and Cluster C personality disorder traits; and maternal neglect and Cluster A personality disorder traits after controlling for co-occurring maltreatment types and personality disorder traits. Results did not support an independent relationship between sexual abuse and borderline personality traits nor between emotional abuse and narcissistic personality disorder traits. Additionally, there were three unexpected findings: physical abuse was independently and positively associated with narcissistic and paranoid traits and negatively associated with Cluster C traits. These findings can help refine our understanding of adult personality pathology and support the future development of clinical tools for survivors of childhood maltreatment.

Depression and demoralization among Russian-Jewish immigrants in primary care

The purpose of this study was to examine the levels and nature of psychological distress and depression among Russian-Jewish émigrés in primary care. Fifty-seven consecutive patients at the primary care clinic were assessed with the Hamilton Depression Scale (Ham-D). The subjects completed self-rating scales, including the Beck Depression Inventory (BDI), Life Orientation Test, Beck Hopelessness Scale, Attributional Style Questionnaire, and Snaith-Hamilton Pleasure Scale. Data on demographics and physical complaints were collected and analyzed. Of the patients studied, 82.5% experienced psychological distress (BDI > or = 10), and 43.9% had clinically significant depressive symptoms (Ham-D > or = 17). BDI and Ham-D scores were significantly correlated with the number of psychosomatic complaints, hopelessness, lack of optimism, anhedonia, and dysfunctional attributional style. The distressed, but not depressed, patients had preservation of hedonic capacity. The authors found a high rate of depression based upon Ham-D scores among the Russian-Jewish émigrés in primary care. The authors suggest that this high rate is attributable to a culturally specific tendency to express distress in somatic terms. The nature of distress was phenomenologically similar to demoralization.

Emergency Room Validation of the Revised Suicide Trigger Scale (STS-3): A Measure of a Hypothesized Suicide Trigger State

Background The Suicide Trigger Scale (STS) was designed to measure the construct of an affective ‘suicide trigger state.’ This study aims to extend the inpatient setting validation study of the original Suicide Trigger Scale version 2 to the revised Suicide Trigger Scale version 3 (STS-3) in an acute psychiatric emergency room setting. Methods The 42-item STS-3 and a brief psychological test battery were administered to 183 adult psychiatric patients with suicidal ideation or attempt in the psychiatric emergency room, and re-administered to subjects at 1 year follow up. Factor analysis, linear and logistic regressions were used to examine construct structure, divergent and convergent validity, and construct validity, respectively. Results The STS-3 demonstrated strong internal consistency (Cronbach’s alpha 0.94). Factor analysis yielded a three-factor solution, which explained 43.4% of the variance. Principal axis factor analysis was used to identify three reliable subscales: Frantic Hopelessness, Ruminative Flooding, and Near-Psychotic Somatization (Cronbach’s alphas 0.90, 0.80, and 0.76, respectively). Significant positive associations were observed between Frantic Hopelessness and BSI depression and anxiety subscales, between Ruminative Flooding and BSI anxiety and paranoia subscales, and Near Psychotic Somatization and BSI somatization subscales. Suicidal subjects with suicide attempt history had mean scores 7 points higher than those without history of suicide attempts. Frantic hopelessness was a significant predictor of current suicide attempt when only attempts requiring at least some medical attention were considered. Conclusion The STS-3 measures a distinct clinical entity, provisionally termed the ‘suicide trigger state.’ Scores on the STS-3 or select subscales appear to relate to degree of suicidality in terms of severity of ideation, history of attempt, and presence of substantive current attempts. Further study is required to confirm the factor structure and better understand the nature of these relations.

Opioid receptor imaging and displacement studies with [6-O-[11C]methyl]buprenorphine in baboon brain

Buprenorphine (BPN) is a mixed opiate agonist-antagonist used as an analgesic and in the treatment of opiate addiction. We have used [6-O-[11C]methyl]buprenorphine ([11C]BPN) to measure the regional distribution in baboon brain, the test-retest stability of repeated studies in the same animal, the displacement of the labeled drug by naloxone in vivo, and the tissue distribution in mice. The regional distribution of radioactivity in baboon brain determined with PET was striatum > thalamus > cingulate gyrus > frontal cortex > parietal cortex > occipital cortex > cerebellum. This distribution corresponded to opiate receptor density and to previously published data (37). The tracer uptake in adult female baboons showed no significant variation in serial scans in the same baboon with no intervention in the same scanning session. HPLC analysis of baboon plasma showed the presence of labeled metabolites with 92% +/- 2.2% and 43% +/- 14.4% of the intact tracer remaining at 5 and 30 min, respectively. Naloxone, an opiate receptor antagonist, administered 30-40 min after tracer injection at a dose of 1.0 mg/kg i.v., reduced [11C]BPN binding in thalamus, striatum, cingulate gyrus, and frontal cortex to values 0.25 to 0.60 of that with no intervention. There were minimal (< 15%) effects on cerebellum. Naloxone treatment significantly reduced the slope of the Patlak plot in receptor-containing regions. These results demonstrate that [11C]BPN can be displaced by naloxone in vivo, and they affirm the feasibility of using this tracer and displacement methodology for short-term kinetics studies with PET. Mouse tissue distribution data were used to estimate the radiation dosimetry to humans. The critical organ was the small intestine, with a radiation dose estimate to humans of 117 nrad/mCi.

Predictive validity of the Suicide Trigger Scale (STS-3) for post-discharge suicide attempt in high-risk psychiatric inpatients.

Background The greatly increased risk of suicide after psychiatric hospitalization is a critical problem, yet we are unable to identify individuals who would attempt suicide upon discharge. The Suicide Trigger Scale v.3 (STS-3), was designed to measure the construct of an affective ‘suicide trigger state’ hypothesized to precede a suicide attempt (SA). This study aims to test the predictive validity of the STS-3 for post-discharge SA on a high-risk psychiatric-inpatient sample. Methods The STS-3, and a psychological test battery measuring suicidality, mood, impulsivity, trauma history, and attachment style were administered to 161 adult psychiatric patients hospitalized following suicidal ideation (SI) or SA. Receiver Operator Characteristic and logistic regression analyses were used to assess prediction of SA in the 6-month period following discharge from hospitalization. Results STS-3 scores for the patients who made post-discharge SA followed a bimodal distribution skewed to high and low scores, thus a distance from median transform was applied to the scores. The transformed score was a significant predictor of post-discharge SA (AUC 0.731), and a subset of six STS-3 scale items was identified that produced improved prediction of post-discharge SA (AUC 0.814). Scores on C-SSRS and BSS were not predictive. Patients with ultra-high (90th percentile) STS-3 scores differed significantly from ultra-low (10th percentile) scorers on measures of affective intensity, depression, impulsiveness, abuse history, and attachment security. Conclusion STS-3 transformed scores at admission to the psychiatric hospital predict suicide attempts following discharge among the high-risk group of suicidal inpatients. Patients with high transformed scores appear to comprise two clinically distinct groups; an impulsive, affectively intense, fearfully attached group with high raw STS-3 scores and a low-impulsivity, low affect and low trauma-reporting group with low raw STS-3 scores. These groups may correspond to low-plan and planned suicide attempts, respectively, but this remains to be established by future research.

Ensuring Research Competency in Psychiatric Residency Training

ObjectiveThis article discusses the importance of research training in psychiatric residency programs and makes recommendations for enhancement.MethodsThe authors examine the literature detailing the shortage of psychiatrist-researchers and the limitations of research training during residency. The authors then describe the Psychiatrists Acquiring Research Training (PART) program at Beth Israel Medical Center that attempts to address this problem. Data collected on resident scholarly activity, including publications and presentations, is presented.ResultsSince its inception, all scholarly activities have increased under the PART program. The 89 residents, followed over 5 academic years, co-authored 32 publications, gave 56 presentations, and re]prestigious honors such as NIMH fellowships and national research awards.ConclusionResidents’ participation in research has been advanced through participation in PART. Ensuring research competency among all psychiatrists is crucial to providing the best science-based care; PART represents a cost-effective way to integrate research training with psychiatric residency. The authors also discuss opportunities and obstacles to developing research programs as part of psychiatric residency training.

Negative symptoms in stroke patients and length of hospital stay

The purpose of this study was to assess whether the presence and severity of psychiatric symptoms in stroke patients correlate with their length of stay (LOS) in a rehabilitation unit, with special emphasis on the role of negative symptoms (NS). Twenty-three stroke patients, consecutively recruited from the inpatient rehabilitation unit, were evaluated on admission with the Mini-Mental State Examination (MMSE), the Positive and Negative Symptom Scale (PANSS), the Hamilton Depression Rating Scale (HDRS), the Scale for Assessment of Negative Symptoms (SANS), and the Functional Independent Measure (FIM). NS scores significantly correlated with LOS, with SANS total score being the most informative, and the attentional impairment subscale the least. The group of patients with pronounced NS stayed in the hospital twice as long as patients with the score on the NS subscale of PANSS below 16. These two groups did not differ in their cognitive performance or in the positive symptom subscale of PANSS scores. Total FIM score on admission was lower and HDRS scores higher in patients with pronounced NS. However, these differences, unlike those of LOS, have not reached statistical significance. The presence and severity of NS in stroke patients are associated with a longer hospital stay. Identification and treatment of NS might lead to a faster discharge from rehabilitation unit.
