The role of family history in addiction severity and treatment response.

This study examined the relationship between familial history of substance use and addiction severity and treatment outcomes of opiate-dependent patients. The sample was comprised of 281 methadone maintenance patients at a VA or community-based clinic. Using the family history section of the Renard Diagnostic Interview, three familial risk groups were identified based on patients' self-report of their relatives' substance use. The three groups considered both the number and type (e.g., first vs. second degree) of biological relatives with a substance use problem. These three risk groups included: (1) high risk (HR, n = 111), (2) medium risk (MR, n = 80), and (3) low risk (LR, n = 90). HR patients reported a history of more severe asocial behavior at baseline and they reported more medical problems and a greater degree of concurrent alcohol use both prior to and after 6 months of treatment compared to LR patients. In addition, the HR group reported more family/social problems at baseline compared to the MR and LR group and both HR and MR patients reported more psychological problems than LR patients after 6 months of treatment. However, when accounting for baseline differences, the regression analyses demonstrated that familial risk was not predictive of drug treatment outcomes after 6 months of methadone maintenance treatment.

Comparison of embedded and isolated administrations of the California Psychological Inventory's Socialization subscale.

Alternate administration methods were tested for the Socialization (So) subscale of the California Psychological Inventory (CPI; H. G. Gough, 1994; H. G. Gough & P. Bradley, 1996) in 437 young adult men. One method administered the 46 CPI-So items in isolation from the CPI, whereas the 2nd method administered the 46 items embedded in the CPI. External validity measures of antisociality were also administered over the 2 sessions. Isolated administration produced somewhat higher internal consistency and significantly better concurrent validity and demonstrated construct validity as a measure of antisociality. Additional factor analytic studies of the CPI-So and CPI revealed that the 2 CPI-So versions had different factorial structures and that the embedded CPI-So subscale did not retain factorial integrity or an appreciable amount of reliable and uniquely interpretable variance.

The prediction of violent and nonviolent criminal behavior in a methadone maintenance population.

The utility of traits associated with Antisocial Personality Disorder in making risk assessments of violent and nonviolent crimes was examined in 254 subjects sampled from a methadone maintenance population. A factor analysis of a number of baseline measures resulted in five factors measuring hostility, insecure attachment, impaired reality testing, antisocial personality, and empathy. These factors were used in logistic regression analysis to predict charges for violent and nonviolent crimes over a 2-year period. Individuals with high scores on the antisocial personality factor had an increased risk of both violent and nonviolent criminal charges. Individuals with low scores on the empathy factor were at high risk for violent crimes. In an analysis using the factor components rather than the factors, the measures of perspective-taking and a socialization were associated with violent criminal charges, and the measure of psychopathy, but not antisocial behavior, was associated with nonviolent criminal charges. The results support the use of measures of personality traits in addition to measures of a history of antisocial behavior in making violence risk assessments in substance-dependent patients. The DSM construct and diagnosis of Antisocial Personality Disorder may be enhanced by greater emphasis on personality traits associated with antisocial behavior.

Alcohol dependence and abuse in three groups at varying familial alcoholism risk.

Three groups of young men varying in familial alcoholism risk were compared for lifetime and current Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) diagnoses. A withdrawal gate diagnostic model (WGM) requiring withdrawal for a dependence diagnosis was also evaluated. Extremely high lifetime DSM-IV diagnostic rates were found for all groups (> or = 78%), with the highest rate in the highest risk group. Similar group differences obtained for individual criteria or symptoms. Although lifetime diagnostic rates were similar for the WGM and DSM-IV, virtually all cases of dependence were preceded by abuse for the WGM, unlike DSM-IV. The findings underline the importance of distinguishing degrees of familial alcoholism risk. The WGM model temporal onset findings versus DSM-IV and the high lifetime diagnostic rates obtained suggest some limitations of the DSM-IV diagnoses.
