Predicting ongoing adherence to disease modifying therapies in multiple sclerosis: utility of the health beliefs model.

OBJECTIVE: To evaluate ongoing adherence to disease modifying therapies (DMT) among individuals with multiple sclerosis and test the utility of the Health Beliefs Model (HBM) to predict adherence. DESIGN: Telephone survey completed at baseline with monthly telephone follow-up for 6 months. SETTING: Veterans Health Administration. PARTICIPANTS: Eighty-nine veterans with MS actively enrolled in a regional VA MS outpatient clinic currently prescribed DMT. MEASURES: Demographic information. Selected items from the Adherence Determinants Questionnaire (ADQ) and Barriers to Care Scale (BACS). RESULTS: Adherence in this population of ongoing DMT users was relatively high (over 80% achieved 80% adherence at follow-up time points). Logistic regression and hierarchical multiple regression analyses controlling for demographics and disease duration were employed to examine the relationship of HBM constructs of perceived susceptibility, severity, benefits, and barriers to DMT adherence and satisfaction at 2-, 4- and 6-month follow-up. Of the four HBM constructs, only perceived benefits uniquely predicted both outcomes across multiple time points. CONCLUSION: Sustained adherence to DMT remains a challenge for an important minority of individuals with MS. The Health Beliefs Model provides insight into psychosocial mechanisms that maintain adherence behavior. In particular, focus upon the perceived benefits of ongoing DMT therapy may be a promising focus for future interventions.

Variations on the CAGE alcohol screening questionnaire: strengths and limitations in VA general medical patients.

BACKGROUND: Several variations on the CAGE alcohol screening questionnaire have been recommended. This report evaluates modifications and additions to the CAGE. METHODS: Alcohol screening questionnaires were evaluated in male VA general medicine patients (n = 227; mean age, 65.8). Mailed questionnaires included two scoring options for the CAGE (standard and last-year time frames), questions about quantity and frequency of drinking, two questions about episodic heavy drinking, and the question "Have you ever had a drinking problem?" Main analyses compared alcohol screening questions, at various cut-points, to a gold standard of hazardous drinking during the past year (> or =14 drinks/week or > or =5 drinks on an occasion) and/or DSM-III-R alcohol abuse or dependence, based on standardized interviews. RESULTS: The CAGE questionnaire with a past-year time frame was much less sensitive (0.57 vs. 0.77) but more specific (0.82 vs. 0.59) than the standard CAGE for detecting hazardous drinking during the past year and/or DSM-III-R alcohol abuse or dependence. An eight-item questionnaire that included the standard CAGE was most sensitive (0.92) but had low specificity (0.50). A single question about the frequency of drinking > or =6 drinks on an occasion, included in the eight-item questionnaire, was both relatively sensitive (0.77) and specific (0.83). CONCLUSION: The CAGE questionnaire with a past-year time frame was an insensitive alcohol-screening test. An eight-item augmented version of the standard CAGE was the most sensitive. A question about the frequency of drinking > or =6 drinks on an occasion performed better than the standard CAGE, which made it the optimal brief screening test for at-risk drinking.

Brief intervention for heavy-drinking college students: 4-year follow-up and natural history.

OBJECTIVES: This study examined long-term response to an individual preventive intervention for high-risk college drinkers relative to the natural history of college drinking. METHODS: A single-session, individualized preventive intervention was evaluated within a randomized controlled trial with college freshmen who reported drinking heavily while in high school. An additional group randomly selected from the entire screening pool provided a normative comparison. Participant self-report was assessed annually for 4 years. RESULTS: High-risk controls showed secular trends for reduced drinking quantity and negative consequences without changes in drinking frequency. Those receiving the brief preventive intervention reported significant additional reductions, particularly with respect to negative consequences. Categorical individual change analyses show that remission is normative, and they suggest that participants receiving the brief intervention are more likely to improve and less likely to worsen regarding negative drinking consequences. CONCLUSIONS: Brief individual preventive interventions for high-risk college drinkers can achieve long-term benefits even in the context of maturational trends.

Trauma, symptoms of posttraumatic stress disorder, and associated problems among incarcerated veterans.

OBJECTIVE: To help improve treatment for incarcerated veterans, the study examined exposure to trauma, symptoms of posttraumatic stress disorder (PTSD), functional status, and treatment history in a group of incarcerated veterans. METHODS: A convenience sample of 129 jailed veterans who agreed to receive outreach contact completed the Life Event History Questionnaire, the PTSD Checklist-Civilian Version (PCL-C), and the Addiction Severity Index. Participants who had scores of 50 or above on the PCL-C, designated as screening positive for PTSD, were compared with those whose scores were below 50, designated as screening negative for PTSD. RESULTS: Some 112 veterans (87 percent) reported traumatic experiences. A total of 51 veterans (39 percent) screened positive for PTSD, and 78 veterans (60 percent) screened negative. Compared with veterans who screened negative for PTSD, those who screened positive reported a greater variety of traumas; more serious current legal problems; a higher lifetime use of alcohol, cocaine, and heroin; higher recent expenditures on drugs; more psychiatric symptoms; and worse general health despite more previous psychiatric and medical treatment as well as treatment for substance abuse. CONCLUSIONS: The findings encourage the development of an improved treatment model to keep jailed veterans with PTSD from repeated incarceration.

Binge drinking among female Veterans Affairs patients: prevalence and associated risks.

This study evaluated the prevalence and associated risks of binge drinking, defined as having > or = 4 drinks on an occasion in the past year, in a female patient population. Of 1,259 female Veterans Affairs patients surveyed, 780 reported drinking alcohol in the past year, and 305 (24% of respondents, 39% of drinkers) reported binge drinking in the past year; 84 (11% of drinkers) had done so monthly or more often. Age-adjusted logistic regression analyses indicated that women who reported past-year binge drinking monthly or more often reported significantly increased odds of morning drinking (odds ratio [OR] = 40.3), others worrying about their drinking (OR = 38.6), arguments after drinking (OR = 13.5), hepatitis or cirrhosis (OR = 3.1), frequent injuries (OR = 2.6), smoking (OR = 3.7), drug use (OR = 22.2), and multiple sexual partners (OR = 4.6).

The relationship between alcohol screening questionnaires and mortality among male veteran outpatients.

OBJECTIVE: This study evaluated whether responses to alcohol screening questionnaires predicted mortality in a Department of Veterans Affairs (VA) primary care population. METHOD: This study involved 5,703 male outpatients (mean age = 64) who were enrolled in General Internal Medicine clinics at three Veterans Affairs (VA) medical centers and returned mailed questionnaires in 1993-94. The two questionnaires included the CAGE and Alcohol Use Disorders Identification Test (AUDIT) alcohol screening tests. Mortality was ascertained using the VA Beneficiary Identification and Record Locator System. Five-year crude and adjusted mortality rates were calculated for patients who screened positive and patients who screened negative on each alcohol screening test. RESULTS: The risk of mortality was increased among drinkers who scored > or = 8 on the full AUDIT (hazard ratio: 1.47; 95% confidence interval [CI]: 1.08-2.00) or the three AUDIT consumption questions (1.58; 1.11-2.27), after adjusting for age, smoking, sociodemographic characteristics and chronic illnesses. The risk of mortality was also increased among drinkers who reported drinking > or = 3 drinks daily (1.69; 1.28-2.22) or prior alcohol treatment (1.66; 1.27-2.17), in "fully adjusted" models. A positive CAGE score (> or = 2) was associated with significantly increased risk of mortality among drinkers in a model adjusted only for age and smoking (1.27; 1.02-1.58). Among nondrinkers, neither a positive CAGE score (> or = 2) nor report of prior alcohol treatment was associated with increased risk of mortality. CONCLUSIONS: VA outpatients who reported drinking during the previous year and who had a positive result on an alcohol screening test experienced higher mortality over the subsequent 5 years than did patients who screened negative.

Individual drinking changes following a brief intervention among college students: clinical significance in an indicated preventive context.

This study investigated the clinical significance of previously reported statistically significant mean reductions in drinking and related problems among college students in a randomized trial of a brief indicated preventive intervention (G. A. Marlatt et al., 1998). Data were analyzed over a 2-year follow-up for participants from a high-risk intervention group (n = 153), a high-risk control group (n = 160), and a functional comparison group (n = 77). A risk cutpoint for each dependent measure was based on the functional comparison group distribution. Compared with the high-risk controls, more individuals in the high-risk intervention group improved and fewer worsened, especially on alcohol-related problems and, to a lesser extent, on drinking pattern variables. These data from a prevention context clarify the magnitude and direction of individual change obscured by group means.

Detecting bipolar disorder among treatment-seeking substance abusers.

Bipolar disorder is increasingly recognized to have frequent comorbidity with substance use disorders, but may be difficult to diagnose among patients with active substance use. The purpose of this paper is to describe a brief, self-report form for the efficient detection of bipolar disorder. The 19-item form was piloted in 373 consecutive applicants for substance abuse treatment at an urban Veterans Affairs (VA) medical center. Results show reasonable internal consistency (alpha = .850) and high rates of manic symptomatology (36%), previous bipolar diagnosis (30%, 51% of whom report prior psychiatric hospitalization), and exposure to mood stabilizers (20%, 66% of whom reported therapeutic benefit). Comparison of nine different scoring algorithms with chart diagnosis as the validating criterion found that self-report of bipolar diagnosis was optimally sensitive. Either self-report of bipolar diagnosis with hospitalization or self-report of exposure to mood stabilizers with therapeutic response was optimally specific. Symptom self-report items had significantly poorer sensitivity and specificity (F = 7.60, p < .01). We conclude that questions pertaining to diagnostic and treatment history (especially hospitalization or therapeutic medication response) are considerably superior to symptom-based screening for clinically diagnosed bipolar disorder. Further work using structured interview as the diagnostic criterion is under way to validate this instrument.

Integrating skills training and motivational therapies. Implications for the treatment of substance dependence.

Two well-articulated models of substance abuse treatment, skills training and motivational enhancement, have received considerable research attention in recent years. Skills training treatments operate on the underlying rationale of correcting skills deficits, whereas motivational strategies are based on affecting clients' willingness to use skills they already possess. Skills training and motivational enhancement are typically described as distinct treatments and have recently been constructed as different treatments within a large multisite trial in the United States (Project MATCH). This article explores how treatments for substance abuse can draw from and integrate skills training and motivational strategies. Recovery from addictive patterns of behavior often requires learning over time and typically involves slips, relapses, and multiple quit attempts. Therapeutic support for change in addictive behavior, in particular attempting to prevent and minimize relapse, requires assessment and support of both why one might pursue change (motivation) and how one can best be successful (skills).

The AUDIT alcohol consumption questions: reliability, validity, and responsiveness to change in older male primary care patients.

OBJECTIVES: To determine the reliability, validity, and responsiveness to change of AUDIT (Alcohol Use Disorders Identification Test) questions 1 to 3 about alcohol consumption in a primary care setting. PATIENTS: Randomly selected, male general medical patients (n = 441) from three VA Medical Centers, who had 5 or more drinks containing alcohol in the past year and were willing to be interviewed about their health habits. MEASURES: Three self-administered AUDIT consumption questions were compared with a telephone-administered version of the trilevel World Health Organization interview about alcohol consumption. RESULTS: Of 393 eligible patients, 264 (67%) completed interviews. Test-retest reliability--Correlations between baseline and repeat measures 3 months later for four dimensions of consumption according to the AUDIT, ranged from 0.65 to 0.85, among patients who indicated they had not changed their drinking (Kendall's Tau-b). Criterion validity--Correlations between AUDIT and interview for four dimensions of alcohol consumption ranged from 0.47 to 0.66 (Kendall's Tau-b). Discriminative validity--The AUDIT questions were specific (90 to 93%), but only moderately sensitive (54 to 79%), for corresponding criteria for heavy drinking. Responsiveness to change--The AUDIT consumption questions had a Guyatt responsiveness statistic of 1.04 for detecting a change of 7 drinks/week, suggesting excellent responsiveness to change. CONCLUSIONS: AUDIT questions 1 to 3 demonstrate moderate to good validity, but excellent reliability and responsiveness to change. Although they often underestimate heavy alcohol consumption according to interview, they performed adequately to be used as a proxy measure of consumption in a clinical trial of heavy drinkers in this population.

The AUDIT alcohol consumption questions (AUDIT-C): an effective brief screening test for problem drinking. Ambulatory Care Quality Improvement Project (ACQUIP). Alcohol Use Disorders Identification Test.

OBJECTIVE: To evaluate the 3 alcohol consumption questions from the Alcohol Use Disorders Identification Test (AUDIT-C) as a brief screening test for heavy drinking and/or active alcohol abuse or dependence. METHODS: Patients from 3 Veterans Affairs general medical clinics were mailed questionnaires. A random, weighted sample of Health History Questionnaire respondents, who had 5 or more drinks over the past year, were eligible for telephone interviews (N = 447). Heavy drinkers were oversampled 2:1. Patients were excluded if they could not be contacted by telephone, were too ill for interviews, or were female (n = 54). Areas under receiver operating characteristic curves (AUROCs) were used to compare mailed alcohol screening questionnaires (AUDIT-C and full AUDIT) with 3 comparison standards based on telephone interviews: (1) past year heavy drinking (>14 drinks/week or > or =5 drinks/ occasion); (2) active alcohol abuse or dependence according to the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition, criteria; and (3) either. RESULTS: Of 393 eligible patients, 243 (62%) completed AUDIT-C and interviews. For detecting heavy drinking, AUDIT-C had a higher AUROC than the full AUDIT (0.891 vs 0.881; P = .03). Although the full AUDIT performed better than AUDIT-C for detecting active alcohol abuse or dependence (0.811 vs 0.786; P<.001), the 2 questionnaires performed similarly for detecting heavy drinking and/or active abuse or dependence (0.880 vs 0.881). CONCLUSIONS: Three questions about alcohol consumption (AUDIT-C) appear to be a practical, valid primary care screening test for heavy drinking and/or active alcohol abuse or dependence.

Screening and brief intervention for high-risk college student drinkers: results from a 2-year follow-up assessment.

This randomized controlled trial evaluated the efficacy of a brief intervention designed to reduce the harmful consequences of heavy drinking among high-risk college students. Students screened for risk while in their senior year of high school (188 women and 160 men) were randomly assigned to receive an individualized motivational brief intervention in their freshman year of college or to a no-treatment control condition. A normative group selected from the entire screening pool provided a natural history comparison. Follow-up assessments over a 2-year period showed significant reductions in both drinking rates and harmful consequences, favoring students receiving the intervention. Although high-risk students continued to experience more alcohol problems than the natural history comparison group over the 2-year period, most showed a decline in problems over time, suggesting a developmental maturational effect.

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.

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.

High-risk drinking across the transition from high school to college.

Alcohol use and related problems were studied from the senior year in high school to the first autumn in college for 366 heavy drinking students. Four risk factors-subject sex, family history of drinking problems, prior conduct problems, and type of college residence-were evaluated as predictors of: (1) differential changes in drinking rates, (2) differential changes in alcohol-related problems, and (3) alcohol dependence symptoms during the first college term. Results suggest that both dispositional and environmental factors are associated with changes in drinking rates and the existence of dependence symptoms. Increases in the frequency of drinking were specifically and strongly associated with residence in a fraternity (men) or sorority (women). Three risk factors were associated with increased quantity of drinking: male gender, residence in a fraternity or sorority, and a history of conduct problems. Prior conduct problems were also consistently associated with dependence symptoms during the first term in college. A family history of alcohol problems was not consistently related to changes in use rates or problems, although some analyses suggest interactive effects. Early interventions on college campuses should target individuals using additive risk profiles.

The Alcohol Skills Training Program: a group intervention for young adult drinkers.

Development, content, and evaluation of the Alcohol Skills Training Program (ASTP) is described. Patterned after strategies for relapse prevention, the ASTP is a cognitive behavioral approach to the secondary prevention of alcohol problems. Format and context of the six group sessions are detailed, and process considerations are discussed. Results are summarized for two controlled investigations of the ASTP with young adult drinkers. The psychoeducational approach of the ASTP is recommended as an effective means for changing drinking patterns among young adults who are at risk for alcohol-related problems.

Outcome of contingency contracting for illicit drug use in a methadone maintenance program.

This study evaluates the outcome of a mandatory, clinic wide, structured contingency contracting system in a methadone maintenance program. The system involved weekly urine screening and placement on written individualized contracts for any of 106 male patients who displayed illicit drug use. Methadone dose decreases were the penultimate and detoxification and discharge the ultimate contingencies for unremitting drug use. Sixty subjects (56.6%) received contracts and 36 (35%) eventually left treatment. The contracts did not decrease the overall number of positive urines for the contract subjects, but opiate use did decrease significantly for subjects on more stringent contracts.

An experimental test of three methods of alcohol risk reduction with young adults.

This study tested 3 forms of alcohol risk reduction programming for young adults. Volunteers were randomly assigned to receive a 6-week class and discussion group, a 6-unit self-help manual, or a single 1-hr feedback and advice session with professional staff. Results reveal significant reductions in self-reported drinking at the end of the intervention phase and maintenance of drinking changes throughout a 2-year follow-up period. Comparable drinking reductions were rated across treatments; however, noncompliance with the self-help reading program suggested limited utility. Treatment response was related to subject age, as subjects showed increased drinking during the year they reached legal drinking status. The efficacy of brief motivational interventions and client matching in prevention programs is discussed.
