Little information exists on treatment effectiveness in antisocial personality disorder (ASPD). We investigated the feasibility and effectiveness of carrying out a randomized controlled trial of cognitive behaviour therapy (CBT) in men with ASPD who were aggressive.
                This was an exploratory two-centre, randomized controlled trial in a community setting. Fifty-two adult men with a diagnosis of ASPD, with acts of aggression in the 6 months prior to the study, were randomized to either treatment as usual (TAU) plus CBT, or usual treatment alone. Change over 12 months of follow-up was assessed in the occurrence of any act of aggression and also in terms of alcohol misuse, mental state, beliefs and social functioning.
                The follow-up rate was 79%. At 12 months, both groups reported a decrease in the occurrence of any acts of verbal or physical aggression. Trends in the data, in favour of CBT, were noted for problematic drinking, social functioning and beliefs about others.
                CBT did not improve outcomes more than usual treatment for men with ASPD who are aggressive and living in the community in this exploratory study. However, the data suggest that a larger study is required to fully assess the effectiveness of CBT in reducing aggression, alcohol misuse and improving social functioning and view of others. It is feasible to carry out a rigorous randomized controlled trial in this group. Pharmacotherapy response was compared in 94 cocaine-abusing methadone patients with (n = 75) and without (n = 19) antisocial personality disorder (ASP), in a 12-week, randomized, double-blind trial using desipramine 150 mg daily (n = 30), amantadine 300 mg daily (n = 33), and placebo (n = 31). Retention was lower for the ASP group (ASP 9.6 weeks vs. non-ASP 11.2 weeks). During the first 2 weeks, there was no significant difference in the percentage of cocaine-free urines between the ASP vs. non-ASP patients (9% vs. 18%), but during the last 2 weeks, the non-ASP patients showed a significantly greater percentage of cocaine-free urines (30% vs. 7%). Placebo-treated patients in both groups demonstrated no significant difference in their urine toxicologies comparing the first to the last two weeks of treatment. However, the percentage of cocaine-free urines increased from 15% to 32% in medicated non-ASP patients, but showed no change in medicated ASP patients. Thus, antisocial personality disorder was a poor prognostic factor for treatment retention and continued cocaine abuse, and medication did not improve treatment outcome for the ASP patients, but did for the non-ASP patients. This study compared the efficacy of 2 approaches for the treatment of cocaine dependence among methadone-maintained patients with and without antisocial personality disorder (ASPD). Patients were randomly assigned to 4 study conditions: cognitive-behavioral treatment (CBT), contingency management (CM), CBT with CM, or methadone maintenance. The Structural Clinical Interview for Mental Disorders-IV was administered to 108 patients to assess ASPD. A 2-way analysis of variance showed that patients with ASPD were more likely to abstain from cocaine use during treatment than patients without ASPD. The strong treatment effect for ASPD patients was primarily due to the CM condition. Regression analyses showed that ASPD remained significantly related to CM treatment responsivity while controlling for other factors. Antisocial personality disorder (APD) is associated with increased problem severity in treatment-seeking opioid-dependent patients. Treatment studies have reported mixed results but generally show that patients with APD make progress that is often comparable to drug-dependent patients without the personality disorder. Much of this work is based on secondary analyses of studies evaluating responses to a variety of drug abuse treatment interventions. This study reports on a randomized prospective trial evaluating a behavioral approach for managing opioid-dependent patients with APD. Subjects (N = 100) met Diagnostic and Statistical Manual of Mental Disorders criteria for opioid dependence and APD using a structured clinical interview and were randomly assigned to either an experimental condition (n = 51), which used a highly structured contingency management intervention, or a control condition (n = 49), which reflected standard methadone treatment. Subjects in the experimental group had significantly better counseling attendance and some indication of lower psychosocial impairment compared to the control group. The experimental intervention increased attendance in subjects with low and high levels of psychopathy and with and without other psychiatric comorbidity. These findings support the development of interventions more tailored to drug-dependent patients with APD. The aim of this project was to assess whether outreach visits would improve the implementation of evidence based clinical practice in the area of falls reduction and stroke prevention in a residential care setting.
                Twenty facilities took part in a randomized controlled trial with a seven month follow-up period. Two outreach visits were delivered by a pharmacist. At the first a summary of the relevant evidence was provided and at the second detailed audit information was provided about fall rates, psychotropic drug prescribing and stroke risk reduction practices (BP monitoring, aspirin and warfarin use) for the facility relevant to the physician. The effect of the interventions was determined via pre- and post-intervention case note audit. Outcomes included change in percentage patients at risk of falling who fell in a three month period prior to follow-up and changes in use of psychotropic medications. Chi-square tests, independent samples t-test, and logistic regression were used in the analysis.
                Data were available from case notes at baseline (n = 897) and seven months follow-up (n = 902), 452 residential care staff were surveyed and 121 physicians were involved with 61 receiving outreach visits. Pre-and post-intervention data were available for 715 participants. There were no differences between the intervention and control groups for the three month fall rate. We were unable to detect statistically significant differences between groups for the psychotropic drug use of the patients before or after the intervention. The exception was significantly greater use of "as required" antipsychotics in the intervention group compared with the control group after the pharmacy intervention (RR = 4.95; 95%CI 1.69-14.50). There was no statistically significant difference between groups for the numbers of patients "at risk of stroke" on aspirin at follow-up.
                While the strategy was well received by the physicians involved, there was no change in prescribing patterns. Patient care in residential settings is complex and involves contributions from the patient's physician, family and residential care staff. The project highlights challenges of delivering evidence based care in a setting in which there is a paucity of well controlled trial evidence but where significant health outcomes can be attained. This double-blind, placebo-controlled, 6-month follow-up treatment study investigated the efficacy of bromocriptine and nortriptyline in attenuating drinking behavior and psychiatric symptoms in 216 male alcoholic patients subtyped by comorbid psychiatric disorder(s). Three well-defined subtypes were examined: alcoholism only, alcoholism + affective/anxiety disorder, and alcoholism + antisocial personality disorder. It was hypothesized that both medications would relieve negative affective symptoms associated with alcohol use and would be particularly effective for the affective/anxiety subgroup. Contrary to our predictions, the only significant effects found were with the antisocial personality disorder patients who were receiving nortriptyline. One interpretation of the results was that nortriptyline may have reduced impulsive drinking in the antisocial personality disorder subgroup by actions on serotonergic neurotransmission. To investigate if ethyl-eicosapentaenoic acid (E-EPA) augmentation improves antipsychotic efficacy and tolerability in first-episode psychosis (FEP).
                We performed a 12-week, randomized, double-blind, placebo-controlled trial of 2-g E-EPA augmentation in 80 FEP patients. Sixty-nine patients were eligible for analysis; a post hoc analysis was computed for a subgroup of nonaffective FEP patients (N = 53). The first participant was included in November 2000 and the last participant completed the trial in August 2003. Primary outcome measures were symptom change scores and time to first response, while tolerability measures and cumulative antipsychotic dose were secondary outcome measures.
                Analysis of covariance controlling for baseline symptoms found no significant mean difference between E-EPA and placebo at week 12 for symptom change scores. Cox regression analysis revealed a significant treatment by diagnosis interaction (p = .024) for time to first response favoring E-EPA in nonaffective psychosis. Post hoc analysis for cumulative response rates further confirmed a higher response rate at week 6 (42.9% [15/35] vs. 17.6% [6/34] for all participants, p = .036; 54.2% [13/24] vs. 17.2% [5/29] for the nonaffective psychosis subset, p = .008); however, the difference at week 12 was no longer significant. Analysis of secondary outcome measures revealed that E-EPA-augmented participants needed 20% less antipsychotic medication between weeks 4 through 6 (p = .03), had less extrapyramidal side effects in the initial 9 weeks (p < .05 for all participants and for all timepoints), and reported less constipation (p = .011) and fewer sexual side effects (p = .016) than those treated with antipsychotic medication alone.
                The findings suggest that E-EPA may accelerate treatment response and improve the tolerability of antipsychotic medications. However, it was not possible to demonstrate a sustained symptomatic benefit of E-EPA in early psychosis, possibly due to a ceiling effect, since a high proportion of first-episode patients already achieve symptomatic remission with antipsychotic medication alone. Further controlled trials in nonaffective early psychosis seem warranted.
                Australian Clinical Trials Registry identifier 12605000267651 (http://actr.org.au). Violent behavior of patients with schizophrenia prolongs hospital stay and interferes with their integration into the community. Finding appropriate treatment of violent behaviors is of primary importance.
                To compare the efficacy of 2 atypical antipsychotic agents, clozapine and olanzapine, with one another and with haloperidol in the treatment of physical assaults and other aggressive behaviors in physically assaultive patients with schizophrenia and schizoaffective disorder.
                Randomized, double-blind, parallel-group, 12-week trial. Physically assaultive subjects with schizophrenia or schizoaffective disorder who were inpatients in state psychiatric facilities were randomly assigned to treatment with clozapine (n = 37), olanzapine (n = 37), or haloperidol (n = 36).
                Number and severity of physical assaults as measured by the Modified Overt Aggression Scale (MOAS) physical aggression score and the number and severity of all aggressive events as measured by the MOAS overall score. Psychiatric symptoms were assessed through the Positive and Negative Syndrome Scale (PANSS).
                Clozapine was superior to both olanzapine and haloperidol in reducing the number and severity of physical assaults as assessed by the MOAS physical aggression score and in reducing overall aggression as measured by the MOAS total score. Olanzapine was superior to haloperidol in reducing the number and severity of aggressive incidents on these 2 MOAS measures. There were no significant differences among the 3 medication groups in improvement of psychiatric symptoms as measured by the PANSS total score and the 3 PANSS subscales.
                Clozapine shows greater efficacy than olanzapine and olanzapine greater efficacy than haloperidol in reducing aggressive behavior. This antiaggressive effect appears to be separate from the antipsychotic and sedative action of these medications. We examined the effect of a case management intervention on drug treatment entry among injection drug users (IDUs) with and without comorbid antisocial personality disorder (ASPD). Injection drug users attending the Baltimore Needle Exchange Program who sought and were granted referrals to opioid agonist treatment were randomized to receive a strengths-based case management intervention or passive referral. Of 162 IDUs, 22.8% met the DSM-IV criteria for ASPD. Compared to those without ASPD, IDUs with comorbid ASPD who spent 25 or more minutes with their case manager prior to their treatment entry date were 3.51 times more likely to enter treatment than those receiving less than 5 min, adjusting for intervention status, race, and treatment site (95% confidence interval 1.04-11.89). Providing case management services to IDUs with comorbid ASPD may facilitate treatment entry and reduce the negative consequences of drug abuse.
The body of evidence summarised in this review is insufficient to allow any conclusion to be drawn about the use of pharmacological interventions in the treatment of antisocial personality disorder.
