The impact of craving and impulsivity on aggression in detoxified cocaine-dependent patients.

Patients with substance use disorders are frequently associated with impulsivity that may underlie elevated levels life-threatening types of behavior, including aggression. In addition, craving is a prominent feature of addiction and appears to be closely related to impulsivity. This study assessed the unique contribution of cocaine craving and impulsivity in predicting aggression by means of correlational and mediational analyses. Forty inpatient detoxified cocaine-dependent patients and 40 matched healthy controls were enrolled. These participants filled out the Obsessive Compulsive Drug Use Scale, the Dickman Impulsivity Inventory, and the Aggression Questionnaire. The patient group showed elevated levels of impulsivity and aggression as compared with the control group. Although cocaine craving is positively correlated with both impulsivity and aggression, craving did not mediate the relationship between both constructs. It is concluded that craving does not have an impact on the relationship between impulsivity and trait aggression in this patient sample.

Community reinforcement and family training: an effective option to engage treatment-resistant substance-abusing individuals in treatment.

AIMS: Many individuals with substance use disorders are opposed to seeking formal treatment, often leading to disruptive relationships with concerned significant others (CSOs). This is disturbing, as untreated individuals are often associated with a variety of other addiction-related problems. Community Reinforcement and Family Training (CRAFT) provides an option to the more traditional treatment and intervention approaches. The objective of this systematic review was to compare CRAFT with the Alcoholics Anonymous/Narcotics Anonymous (Al-Anon/Nar-Anon) model and the Johnson Institute intervention in terms of its ability to engage patients in treatment and improve the functioning of CSOs. METHODS: The electronic databases PubMed, PsycINFO, EMBASE, CINAHL and the Cochrane Library were consulted. Four high-quality randomized controlled trials were identified, with a total sample of 264 CSOs. Data were synthesized to quantify the effect with 95% confidence intervals, using the random effects model. RESULTS: CRAFT produced three times more patient engagement than Al-Anon/Nar-Anon [relative risk (RR) 3.25, 95% confidence interval (CI) 2.11-5.02, P < 0.0001; numbers needed to treat (NNT) = 2] and twice the engagement of the Johnson Institute intervention (RR 2.15, 95% CI 1.28-3.62, P = 0.004; NNT = 3). Overall, CRAFT encouraged approximately two-thirds of treatment-resistant patients to attend treatment, typically after [corrected] four to six CRAFT sessions. CSOs showed marked psychosocial and physical improvements whether they were assigned to CRAFT, Al-Anon/Nar-Anon or the Johnson Institute intervention within the 6-month treatment window. CONCLUSION: CRAFT has been found to be superior in engaging treatment-resistant substance-abusing individuals compared with the traditional programmes.

Severity Indices of Personality Problems (SIPP-118): development, factor structure, reliability, and validity.

This article describes a series of studies involving 2,730 participants on the development and validity testing of the Severity Indices of Personality Problems (SIPP), a self-report questionnaire covering important core components of (mal)adaptive personality functioning. Results show that the 16 facets constituted homogeneous item clusters (i.e., unidimensional and internally consistent parcels) that fit well into 5 clinically interpretable, higher order domains: self-control, identity integration, relational capacities, social concordance, and responsibility. These domains appeared to have good concurrent validity across various populations, good convergent validity in terms of associations with interview ratings of the severity of personality pathology, and good discriminant validity in terms of associations with trait-based personality disorder dimensions. Furthermore, results suggest that the domain scores are stable over a time interval of 14-21 days in a student sample but are sensitive to change over a 2-year follow-up interval in a treated patient population. Taken together, the final instrument, the SIPP-118, provides a set of 5 reliable, valid, and efficient indices of the core components of (mal)adaptive personality functioning.

Research issues in forensic psychiatry.

PURPOSE OF REVIEW: Forensic psychiatry is a multidisciplinary specialty within the context of criminal and civil law. This paper reviews a broad spectrum of research areas within the forensic psychiatric field, covering publications in 2006. RECENT FINDINGS: New developments can be divided into four subject areas. The first relates to risk assessment, the second to the epidemiology of violence, the third refers to treatment outcome studies, and the fourth relates to topics of interest within different offender groups. SUMMARY: There seems to be a growing interest in specifying the needs of different offender groups, such as intellectually-disabled patients, adolescents and women. When it comes to effective treatment models for these subgroups, however, it is not always clear if sufficient attention is paid to the presence of comorbid disorders and their consequences, even in research publications.

Interrater reliability of the structured interview for DSM-IV personality in an opioid-dependent patient sample.

We examined the interrater reliability of the Structured Interview for DSM-IV Personality (SIDP-IV) in an opioid-dependent patient sample at the criterion as well as at the diagnostic level for both categorical and dimensional data. At the criterion level (Cohen's kappa ranging from 0.76 to 0.93 and intraclass correlation coefficient ranging from 0.67 to 0.97) as well as at the diagnostic level (Cohen's kappa ranging from 0.66 to 1.00 and intraclass correlation coefficient ranging from 0.88 to 0.99), the reliability was excellent. The results suggest the SIDP-IV to be an adequate instrument for the assessment of personality disorders in opioid-dependent patients.
