Early deviance and related risk factors in the children of narcotic addicts.

This descriptive study examines the self-reported behaviors of 285 male and female adolescent children (ages 12-17) of narcotic addicts participating in methadone maintenance programs. These children responded to an extensive 2.5-hour interview questionnaire focusing on current and past activities, including criminal activities prior to age 12. The findings revealed that early deviance, assessed by self-report measures of both severity and variety, is related to current adolescent drug and alcohol use, association with deviant peers, a negative view of home atmosphere, and psychological symptomatology. These results are contrasted with the retrospective reports of adolescent behavior obtained from adult male narcotic addicts in a prior study of vulnerability to addiction. The comparability of study results is discussed in the context of developmental risk factors, prevention and treatment strategies, and other considerations specifically related to the development of children of narcotic addicts.

Differential contributions of family and peer factors to the etiology of narcotic addiction.

This retrospective study investigated relationships among early family circumstances, peer associations, and narcotic addiction in a sample of 601 urban males. Results of logistic regression analyses indicated that the extent of deviant behavior among close friends at ages 12-14 and disruption in family structure (parental divorce/separation) prior to age 11 were significantly associated with narcotic addiction. Additional regression analyses indicated that deviant behavior among family members, as well as family disruption, experienced prior to age 11, also increased the probability of association with deviant peers and a negative home atmosphere at ages 12-14. Implications of these findings for preventive interventions and for future research are presented.

The family experiences of narcotic addicts and their subsequent parenting practices.

This survey study of male and female narcotic addicts participating in methadone maintenance programs examined self-reported retrospective data on parental behavior experienced by addicts during their adolescent years. These findings were contrasted with the addicts' self-report of their current parenting practices with their own adolescent children. Results showed addicts as perceiving their mothers as significantly more functional in their parenting practices than their fathers on indices of parental involvement, attachment, and responsibility. Significant parenting differences between addicts and their parents were reported for the three indices mentioned, as well as for parent discipline and punitive actions, with the addicts rating their current parenting practices as more effective than those of their parents. Reported parenting practices were further analyzed in the context of how the ratings of parental functioning were related to problems of drug and alcohol abuse exhibited in the home. Findings are discussed in terms of the implications for prevention and treatment approaches for addicts and their children.

The early emergence of narcotic addict types.

Providing retrospective self-reports of their activities, perceptions, and experiences during their early adolescent years (ages 12 to 14), 255 narcotic addicts were classified into four distinct types on the basis of a clustering technique applied to risk factor information derived from five major descriptive domains: family; peer deviance; personal deviance; psychological status; and protective factors. Differentiations among the types largely involved the extent of early drug and other behavioral deviance and family dysfunction. The predictive utility of the typology was examined in terms of outcome over the first ten years of the addiction career, including age at first narcotic addiction, amount of time incarcerated, and percentage of time addicted while in the community. The implications of the typology for both substance abuse prevention and treatment are discussed.

Early family adversity as a precursor to narcotic addiction.

This retrospective study examined differences among three groups of urban males in the prevalence of various family risk factors occurring before age 11 and their independent contributions to subsequent deviance. The groups included: narcotic addicts; never-addicted peer controls who were associates of the addicts at age 11; and never-addicted community controls not associated with the addicts. Sixty-four percent of the addicts, compared to slightly under 40% of both control groups, reportedly experienced one or more family risk factors involving deviant behavior among family members and family disruption before age 11. While community controls differed from addicts on both family deviance and disruption in family structure, peer controls differed from addicts only on disruption of family structure. For the total sample, both family deviance and family disruption experienced before age 11 were significantly associated with crime severity level at age 11. Implications of these findings for future substance abuse research and intervention are discussed.

Perceptions of social pathology in the neighborhood and the etiology of narcotic addiction. A retrospective study.

In this study, we examined whether differential perceptions of poor urban neighborhoods may contribute to narcotic addiction in individuals who grow up in these neighborhoods. Three groups of adult males provided retrospective perceptions of the neighborhoods where they lived at ages 12 to 14. The groups, matched on neighborhood, age, and race, were: narcotic addicts, peer controls--a never-addicted control sample of age-11 associates of the addicts, and community controls--a never-addicted control sample of age-11 peers who did not associate with the addicts. Results suggested clear group differences in perceptions of neighborhood deviance, with addicts perceiving the greatest and community controls the least amount of deviance. However, within groups, subjects who lived in more socially deviant areas, as determined by official records, tended to view their neighborhoods as more deviant than did subjects who lived in less deviant neighborhoods.

The nature and status of drug abuse treatment.

This article focuses on the effectiveness of the major drug abuse treatment modalities (methadone maintenance, therapeutic communities, outpatient drug-free programs, and short-term detoxification) in the United States. It includes findings specific to individual clients and to particular modalities. Methadone maintenance, therapeutic communities, and outpatient drug-free treatment are generally effective in reducing illicit narcotic use and the criminal activity that often accompanies narcotic addiction. These effects are usually short-term, however, and more than one treatment episode is often required for long-term recovery. Longer time in treatment, pretreatment employment, and lack of pretreatment criminality are generally associated with favorable outcome regardless of modality. Issues needing further study, such as treatment for nonnarcotic (mainly cocaine) use, matching clients to treatments, and evaluating the cumulative effects of multiple treatment episodes, are discussed, along with the authors' research on the relationship between drug abuse, crime, and treatment in Maryland.

Clinical predictors of relapse following neuroleptic withdrawal.

The validity of previously hypothesized predictors of elapse following neuroleptic discontinuation was examined. One hundred sixty-two outpatients, with either Research Diagnostic Criteria schizophrenia or schizoaffective disorder, were discontinued from neuroleptic medication for a 28-day period or until judged to be relapsed. Pre-discontinuation neuroleptic dosage level, the severity of psychotic symptoms, and the presence of dyskinetic movements prior to neuroleptic discontinuation were the predictor variables. Of the 162 patients, 62.7% did not relapse during the study period. There were no differences in the survival rates between the patients withdrawn from oral versus depot neuroleptics. Neuroleptic dosage, but not severity of psychotic symptoms or dyskinetic movements, predicted relapse. These results support the hypothesis that pre-withdrawal neuroleptic dosage level predicts relapse, but fail to validate either severity of psychotic symptoms or presence of dyskinetic movements as predictors of relapse.

Carbamazepine maintenance treatment in outpatient schizophrenics.

A double-blind crossover trial was used to evaluate carbamazepine as the sole maintenance treatment of chronic, nonmanic schizophrenic outpatients whose conditions had been stabilized with the use of neuroleptics prior to study. Criteria of treatment effectiveness included the number of patients relapsing and time to relapse over a 95-day neuroleptic-free period during which either carbamazepine or placebo was administered. Relapse was determined by the concordance of psychiatric ratings and independent clinical judgements indicating significant worsening. Results for 27 patients (13 receiving carbamazepine and 14 receiving placebo) involved in the first phase of this treatment comparison were nondifferentiating. Corroborating descriptive findings in the second phase were available for 14 of these patients. There was no evidence supporting the existence of a treatment-relevant subgroup defined by episodic dyscontrol phenomena.

Continuous versus targeted medication in schizophrenic outpatients: outcome results.

The authors report on the outcome of treatment of 116 outpatients with chronic schizophrenia who were assigned to a 2-year, single-blind course of treatment with either targeted or continuous medication. These patients were not restricted to those who were good candidates for a medication reduction strategy. Continuous medication was superior to targeted medication in preventing decompensations and hospitalizations and in extent of employment at 2 years. Other measures of psychopathology and functioning at 1 and 2 years did not differentiate the two groups of patients. The targeted approach achieved a substantial reduction in total medication through a reduction in the number of days of medication administration.

Trends in criminal activity and drug use over an addiction career.

The present study, involving 132 narcotic addicts with multiple periods of addiction, examines trends in criminal activity and drug use over successive periods of addiction and successive periods of nonaddiction during an average 15-year addiction career. Significant decreases over successive addiction periods were found for four (of five) categories of crime: theft, violence, drug distribution, and "other" crime (primarily gambling). These results appear to be accounted for by a disproportionately high level of crime during the first addiction period. Criminal activity, most notably theft and violence, decreased over successive periods of nonaddiction, though not significantly. Although more evidence is needed, a particularly large addiction vs nonaddiction disparity in crime rates for Hispanic addicts revealing a low propensity for crime when not addicted suggests that crime reduction may be a reasonable objective in the treatment of these individuals. With regard to drug use over the addiction career, the most dramatic increases over time were found for illicit methadone and cocaine. Rates of heroin and marijuana use declined. Generally, nonnarcotic drug use, other than use of cocaine and Valium, tended to decrease progressively over time regardless of addiction status. These results, along with findings relevant to the "maturing out of addiction," are discussed.

MMPI-168 profiles of male narcotic addicts by ethnic group and city.

MMPI-168 profiles were obtained on 225 male narcotic addicts who were attending methadone maintenance clinics in Baltimore and New York City during 1983 and 1984. Data were collected on Black and White (Anglo, other than Hispanic) addicts in Baltimore and on Black, Hispanic, and White addicts in New York City. In general, the profiles indicated high levels of psychopathology, with particularly high elevations on the F, D, PD, PT, and Sc scales. Consistent across cities and in agreement with earlier findings, profiles of Whites indicated somewhat more maladjustment than those for Blacks, while the profiles of Hispanics displayed essentially the same levels of disturbance as those for Whites. Comparisons by city revealed greater deviance for New York City subjects, a finding more evident among Whites than among Blacks.

Differences among treatment clinic types in attitudes toward narcotic addiction.

Factor analysis of data from a general survey of attitudes and opinions concerning narcotic addiction and its treatment revealed 10 major dimensions, five of which were likely to have significant implications for drug abuse intervention strategies. For these latter dimensions, differences were determined among clients and staff according to type of treatment clinic (three types involving the provision of methadone maintenance in various combinations with other treatments and one involving the use of abstinence only). The most pronounced differences were between the methadone clinics and those offering abstinence only. Both the clients and staff of abstinence clinics were more skeptical concerning treatment effectiveness, were more negative regarding the use of narcotic drugs, and were more disposed to the use of ex-addict counselors and group procedures in treatment.

Attitudes toward narcotic addiction.

In an effort to isolate the major dimensions of attitude and expectation regarding narcotic addiction and its treatment and to compare different groups of addict/clients and agency staff on these factors, a comprehensive questionnaire was administered to 900 addict/clients and 237 agency personnel in 25 drug treatment clinics in six states. Results of a factor analysis, which used questionnaire data from all of the 1137 subjects so that direct group comparisons could be made, indicated the presence of 10 major dimensions of attitude and expectation. Results also suggested considerable variation, particularly by status (client vs. staff) and ethnic group, on these dimensions. An additional analysis of staff attitudes and expectations revealed correlations with years of education, ex-addict status, and years of work experience. Such findings suggest the need to consider client/staff characteristics and attitudes in the planning of treatment services for narcotic addicts. An abbreviated (53-item) attitude and expectation questionnaire was developed for this purpose.

A comparative trial of pharmacologic strategies in schizophrenia.

An open comparative trial was conducted involving 42 schizophrenic outpatients randomly assigned to one of two methods of drug administration: continuous medication (N = 21) and targeted medication plus psychosocial intervention (N = 21). The results, which suggest an extensive similarity with respect to outcome for the two treatments over a 2-year period, argue for the continuation of research on the relative effectiveness of the targeted drug approach, particularly in cases judged suitable for drug reduction strategies.
