Diagnostic concordance of DSM-III-R, DSM-IV, and ICD-10 inhalant use disorders.

The diagnostic concordance of DSM-III-R, DSM-IV, and ICD-10 inhalant use disorders was assessed using the sample of lifetime inhalant users (n=76) participating in the DSM-IV Field Trial for Substance Use Disorders. Substantially smaller proportions of lifetime inhalant users met DSM-IV inhalant abuse or dependence criteria than met comparable DSM-III-R or ICD-10 criteria. DSM-III-R and ICD-10 performed similarly, although DSM-III-R tended to be more inclusive vis-à-vis diagnoses of inhalant dependence. Kappa coefficients indicated a moderate degree of concordance between the three nosologies for inhalant use disorder diagnosis rates. Inclusion of possible withdrawal symptomatology criteria (that are not normally included) in the DSM-IV and ICD-10 criteria sets for inhalant dependence exerted little effect on diagnosis rates.

Positive by-products of the struggle with chemical dependency.

Focus groups were conducted to identify ways persons in recovery from chemical dependence think they have benefited from their struggles with addiction. Categories of positive by-products were identified independently by two sets of readers. Several of the positive by-products discussed by the focus group participants are commonly reported from other kinds of challenging life experiences. These include increases in self-efficacy, family closeness, closeness with others, compassion and spirituality, and changes in life priorities. Additional positive by-products were discussed by the focus group participants that may be more unique to substance abuse and other similar stressors, including increased self-knowledge, enhanced ability to help offspring with substance abuse-related issues, and decreased naïveté. Ways to incorporate knowledge about these positive by-products into substance abuse treatment programs are introduced.

Pharmacological aversion treatment of alcohol dependence. I. Production and prediction of conditioned alcohol aversion.

Eighty-two hospitalized alcoholics receiving pharmacological aversion therapy (PAT) over a 10-day treatment interval completed cognitive, behavioral, and psychophysiological measures evaluating conditioned aversion to alcohol. Pre-post assessments provided convergent support for the efficacy of PAT vis-à-vis production of conditioned aversion to alcohol. Positive alcohol-related outcome expectancies were significantly reduced, whereas confidence that drinking could be avoided in various high-risk situations for consumption was increased following PAT. Behavioral and cardiac rate assessments revealed significant changes following PAT that were specific to alcoholic beverages and potentially reflective of conditioned alcohol aversion. Patients with more extensive pretreatment experiences with alcohol-associated nausea and greater involvement in antisocial conduct appeared to be less susceptible to the PAT conditioning protocol.

Nurses' attitudes toward substance misusers. II. Experiments and studies comparing nurses to other groups.

Experimental investigations of nurses consistently indicate that a patent labeled as a substance misuser is perceived far more negatively across a range of personal attributes than an identical patient who is not so labeled. Comparative evaluations suggest that nurses are less tolerant of social drinking and drug use and are more morally condemnatory of the chemically dependent than are other health-care professionals.

Nurses' attitudes toward substance misusers. III. Emergency room nurses' attitudes, nurses' attitudes toward impaired nurses, and studies of attitudinal change.

Emergency room nurses generally regard alcohol and drug misusers as troublesome patients and dislike caring for them. Surveys of nurses' and nurse managers' attitudes toward impaired nurses, all published in recent years, suggest that they are generally supportive of impaired nurses and sanguine about their prospects for recovery; nonetheless, a substantial minority oppose the return to work of a formerly substance-misusing nurse colleague. Programs designed to change nurses' attitudes toward substance misusers are generally ineffective, although significant gains in substance-related knowledge are commonly reported.

Nurses' attitudes toward substance misusers. I. Surveys.

Studies of nurses' attitude toward substance misusers, spanning three decades, are reviewed. Survey findings reflect greater acceptance of alcohol and drug misusers in recent years. However, significant minorities of nurses continue to regard substance users as immoral, characterologically defective, and unlikely to recover. Implications of these attitudes for treatment of substance misusers are discussed.

Inhalant use among urban American Indian youth.

AIMS: To assess the prevalence of inhalant use among urban American Indian youth and to examine differences between inhalant users and non-users. DESIGN: Baseline (T1) self-report questionnaires completed in 5th-6th grade and at seven annual follow-up assessments (T2-T8). SETTINGS: Seattle metropolitan area. PARTICIPANTS: Two hundred and twenty-four Indian youth. MEASUREMENTS: Youth-completed measures of substance use, ethnic self-identity, involvement in traditional Indian activities, family conflict, family history of alcoholism, peer and sibling deviance, self-esteem, delinquency, aggression, anxiety, depression, sensation seeking, conduct disorder and alcohol dependence. FINDINGS: Lifetime inhalant use was reported by 12.3% of adolescents. At T1, inhalant users had significantly lower perceived self-worth and average annual household incomes and significantly greater density of familial alcoholism and expression of aggressive and delinquent conduct than non-users. Aggressive behavior was the most important T1 predictor of inhalant use. Lifetime conduct and alcohol dependence disorders were 3.3 and 2.6 times more prevalent among inhalant users than non-users at T5. Inhalant users had more extensive deviant peer networks, were more sensation-seeking, and evidenced lower perceived self-worth than non-users at T8. CONCLUSIONS: Inhalant use was less prevalent in this particular sample of urban Indian adolescents than in most studies of reservation Indian youth. As with other studies of inhalant abuse, aggressive and delinquent males of low SES and low-perceived self-worth with family histories of alcohol dependence, were at highest risk for inhalant use.

Youth crime, public policy, and practice in the juvenile justice system: recent trends and needed reforms.

Historically, juvenile justice policy has oscillated between rehabilitative and punitive approaches to managing young offenders. Policy and practice in the 1970s and 1980s emphasized individual treatment for young offenders in nonsecure, community-based programs. An increase in violent youth crime during the past decade has renewed interest in punishing delinquent youths. Cyclic fluctuations in juvenile justice policy and their relationship to policy, practice, and youth crime are examined. Our analysis suggests that overall crime rates have remained relatively stable over the past three decades and are independent of prevailing juvenile justice policies. The findings support the need for targeted prevention efforts addressing the root causes of juvenile crime. Needed policy reforms, public education efforts, and practice approaches are outlined.

Cloninger's tridimensional theory of personality and psychopathology: applications to substance use disorders.

OBJECTIVE: To evaluate studies that applied Cloninger's tridimensional theory of personality to substance abusers. METHODS: Medline and PsychInfo data bases were searched for studies published between 1986 and mid-1995 that used the Tridimensional Personality Questionnaire (TPQ). A supplemental manual search was conducted to identify additional evaluations of the tridimensional theory. Reports were reviewed if they included substance abusers or related tridimensional traits to substance use measures. RESULTS: Factor analyses did not consistently support the tridimensionality of the TPQ. Novelty Seeking (NS) traits distinguished alcoholics from nonalcoholics, Type B and Type 2 alcoholics from their Type A and Type 1 counterparts, smokers from nonsmokers, and individuals (substance abusers and nonabusers) with and without antisocial personality disorder (ASPD). Tridimensional traits independently predicted early onset alcohol abuse and serious delinquency in studies that did not employ the TPQ and were significantly associated with concurrent substance abuse among adolescents. Most studies that compared nonalcoholic youth with positive and negative family histories of alcoholism reported nonsignificant TPQ differences or very small effects. Few alcoholics, cigarette smokers or sons of alcoholics displayed Type 1 (low novelty seeking, high harm avoidance, high reward dependence) or Type 2 (high novelty seeking, low harm avoidance, low reward dependence) TPQ profiles, but rarely were levels of tridimensional traits determined by reference to established norms. CONCLUSIONS: NS predicts early onset alcohol abuse and criminality and discriminates alcoholics exhibiting antisocial behavior and persons with ASPD from their nonantisocial counterparts. Findings for the Harm Avoidance (HA) and Reward Dependence TPQ subscales are much less consistent. Some support for the role of elevated HA in intensity of substance use has been adduced. At present, the utility of the TPQ for prevention or clinical purposes is not well established.

Essential and reactive alcoholism: a review.

Methodological characteristics and substantive findings of investigations of essential and reactive alcoholics were reviewed. The data base was comprised of approximately 12 studies published between 1951-1992, most of which employed small samples of hospitalized male alcoholics. Psychometric properties of the Essential-Reactive Alcoholism Questionnaire, the instrument generally used to assess the essential-reactive dimensions, rarely were examined. The weight of the evidence suggests that essential alcoholics have earlier onset and greater severity of alcoholism, lower levels of occupational and educational achievement, more interpersonal conflict, fewer long-term friendships, more antisocial attitudes and conduct, greater density of familial alcoholism, more impaired neuropsychological functioning, and lower resting blood pressure than do reactive alcoholics. Research is needed to assess the prognostic utility of the essential-reactive typology and the degree to which the distinction may facilitate patient-treatment matching.

Tridimensional personality traits in sons of alcoholic and nonalcoholic fathers.

Sons of alcoholics (SOAs; n = 27) and sons of nonalcoholics (SONAs; n = 23) were compared across Tridimensional Personality Questionnaire (TPQ) and Sensation Seeking scales and measures of plasma homovanillic acid and platelet monoamine oxidase activity. SOAs and SONAs did not differ significantly on any measure. The pattern of correlations between TPQ and Sensation Seeking scales provided some support for the construct validity of TPQ measures. Scores on the TPQ Novelty Seeking scale and platelet monoamine oxidase activity were significantly inversely associated (r = -0.52, p < 0.02) among SOAs, but not among SONAs (r = -0.06).

Clinical issues related to the costs of alcoholism.

Alcohol (ethanol) use disorders are prevalent in many countries and are associated with significant social and health costs. Little is known, however, about the comparative cost effectiveness of treatments for alcoholism. Pharmacoeconomic evaluations are largely (if not wholly) absent from the alcoholism treatment outcome database. We discuss pharmacological approaches to the treatment of alcohol withdrawal and dependence, describing agents that ameliorate withdrawal symptoms, deter alcohol consumption, reduce alcohol craving and produce conditioned alcohol aversion. Cost-relevant clinical considerations are elucidated and recommendations for cost-conscious pharmacological treatment of alcohol dependence are proffered.

Substance-use and psychiatric disorders among American Indian veterans.

Native American (NA) veterans have rarely been the focus of investigational efforts. We review studies relevant to an assessment of NA substance-use disorders, and discuss findings of the Drug Abuse Treatment Services Evaluation Project pertaining specifically to NA veterans. A larger proportion of NA veterans discharged from VA inpatient care in FY93 were diagnosed with a substance-use disorder compared to the total population of veterans discharged that year. Substance-dependent NAs were more likely to be diagnosed with alcohol-use disorders and posttraumatic stress disorder, and less likely to be diagnosed with drug-use disorders and other psychiatric disorders than substance-dependent veterans generally.

Alcohol abuse in urban Indian adolescents and women: a longitudinal study for assessment and risk evaluation.

Empirical studies of American Indian health and mental health have focused primarily on reservation samples or small cross-sectional school-based or treatment samples. Few studies have addressed these issues among urban American Indian populations. This paper introduces an ongoing ten-year prospective longitudinal study of alcohol abuse, drug abuse, and mental health status in a community sample of urban American Indian adolescents and women. The study uses structured interviews and diagnostic assessments to identify risk factors for, and measure prevalence of, alcohol abuse, drug abuse, and psychopathology in 523 Indian youth and 276 Indian women. Study aims, rationale, research design, methods, sample characteristics, assessment instruments, and substance use prevalence are described, and methodological issues related to conducting longitudinal research are discussed.

Synovial chondromatosis in a great horned owl (Bubo virginianus).

A case of synovial chondromatosis in a great horned owl (Bubo virginianus) was found in June 1993. In radiographs of bilateral swelling of the scapulohumeral joint we observed numerous mineralized foci in the soft tissue. The foci were identified by light microscopy as cartilaginous metaplasia. This is the first report of synovial chondromatosis in an owl.
