Which Interventions Work?
Where to refer alcohol abusers for treatment has be under debate for years. In an attempt to address this debate, a recent study compared referral to "intensive" hospital treatment near referral to "less intensive" self-help treatment and next to a choice of treatment options.
American industry have become increasingly aware of the physical, social, psychological, and economic costs of problem drinking to the individual worker and to the larger work business. National estimates of the economic and social costs of alcohol foul language lay a major share of the burden at industry's door. Employers sustain productivity losses and substantial treatment costs, covered through hand benefit plans, for alcohol abuse per se, as okay as even greater costs of medical treatment for illnesses secondarily related to alcohol abuse. Equally worrisome are the potential court liability and public relations costs of alcohol-related incidents, brought home vividly to the business community after the Exxon Valdez oil spill. The significantly publicized conviction of three Northwest Airlines pilots who were observed drinking heavily and boisterously shortly back a morning flight, as well as a little tragic alcohol-related accidents, have further raised consciousness.
In olden times, corporate America has commonly been justly accuse of engaging within a form of institutional denial of the existence of drinking problems. A great deal of research have been done over the years, seeking to recognize and improve the admin of drinking problems in the workplace. Much of this investigation has followed surrounded by the tradition established in a classic 1951 study by Straus and Bacon. The purpose of the study be to demonstrate that alcoholics are in job, not just on skid row, and to entice employers of the suitability of sponsoring programs to identify and treat workers who are problem drinkers. Survey research has shown that senior manager in most colossal corporations no longer need to be convinced of the existence or severity of drinking-related problems (Mercer Meidinger Hansen 1986).
Employee assistance programs (EAPs) own been the preeminent vehicle through which American employer have address problems related to alcohol use, and the number of EAPs has expanded hurriedly since the early 1970s. As their most essential function, EAPs facilitate the designation of employees beside drinking and other coping problems, assess the nature and severity of the problems, and cause referrals for appropriate prudence (see the article by Erfurt and Foote, pp. 154-159, for more information on EAPs). Yet, for the most part, the assessment and referral process have remained a "black box," and the question of where on earth to refer clients has be left for individual counselors to answer. Those who look to research for answers find little guidance on alternative strategies for making referral to alcoholism treatment. Most treatment-comparison studies are carried out in clinical settings, divorced from the workplace. Because EAPs can rear their referrals near the implicit or explicit threat of job loss, they can create distinct incentives for patients to enter alcoholism treatment. Prior research examining treatment efficacy did not own this advantage and for this reason the results of that research may not apply as directly as they should to treatment initiated by an EAP--an increasingly common situation.
QUESTIONS ABOUT ALCOHOLISM TREATMENT
The alcoholism enclosed space has long be divided over how much treatment is enough, and specifically over whether and when inpatient exactness is justified to supervise alcohol deduction and manage alcohol dependence. The highlight 1977 English study (Edwards et al. 1977), in which Griffith Edwards and his colleagues found that "warning" was a short time ago as effective as full-scale treatment, threw down a gauntlet for proponents of more intensive approaches to alcoholism treatment. A complete line of related research, comparing inpatient treatment beside a variety of alternatives (such as outpatient treatment, partial hospitalization, and hours of daylight clinic settings), has once in a while found significant differences in outcomes. More lately, government and private panel (U.S. Congress, Office of Technology Assessment 1983; Institute of Medicine 1989, 1990; National Institute on Alcohol Abuse and Alcoholism [NIAAA] 1990), and several academic reviewers (Miller and Hester 1980; Emrick 1975), hold synthesized the accumulated evidence on alcoholism treatment efficacy. They own concluded that inpatient rehabilitation still awaits convincing justification imminent larger scale studies, and research to develop procedures for harmonizing patients to specific treatments that will best serve their particular wishes.
Ironically, at just the time when this details of caution be building in the research literature, inpatient rehabilitation programs for alcoholism were expanding sharply in the United States. The growth be most pronounced during the 1970s and 1980s, and was supported to a great extent by decision and incentives in private-sector employment. With more EAPs in place, more problem-drinking employees be being identified and referred for assistance. Four interrelated reasons explain why EAPs tend to make referral to inpatient settings.
First, most medical insurance provided much fuller--and sometimes exclusive--coverage for in-hospital care. Second, sickness and fluke plans ensured wage replacement during the member of staff's time away from work. Third, an inpatient referral simplified the EAP administrator's life; managing a problem-drinking member of staff's entry into treatment was commonly a difficult, time-consuming, and emotionally charged task. For a busy administrator facing a choice between transferring that responsibility to an inpatient program, or instinctively having to orchestrate and monitor the client's successful integration into a nonresidential alternative, the inpatient route clearly be the path of smallest resistance. Fourth, the financial impact of these decisions be practically invisible to the administrator making them. The costs of both the inpatient stay and the wage replacement were buried elsewhere surrounded by experience-rated health benefit programs and insurance plans, lower than a jurisdiction that was mostly quite separate from the EAP.
From a policy perspective, this combination--growing numbers of EAPs, beside built-in forces to fuel an expansion of inpatient capacity and next to little financial control or accountability--was an occasion for concern contained by the absence of quantifiable evidence to justify increasing investments in inpatient rehabilitation programs for alcohol dependence and invective.
By the early 1990s, the pendulum be swinging back. Alarmed at their inability to contain rising condition care costs, the Nation's full-size employers be beginning to dull their coverage for alcoholism treatment. Many corporations took steps to limit coverage to a specified number of treatments over a year and/or a lifetime; to increase copayment fees; and/or to palm off incentives that would channel personnel into a variety of manage care programs. The mission of these programs be to reduce admission and lengths of stay for vigour care contained by general and, habitually, for chemical dependency treatment in demanding.
Over this three-decade span, then, the pendulum swung from more to smaller number enthusiasm and coverage for inpatient treatment of workers' alcohol problems. There were few convincing notes on either side of the arc, and no argument on which decision maker could gauge realistically what effect the change might have on the robustness of workers, or on the smooth functioning of the work organization. Virtually all research examining the sound out of how much treatment is enough have posed the question surrounded by clinical settings, removed from the workplace where unsophisticated decisions be often man made as to whether an employee would be hospitalized.
A WORK SITE-BASED TREATMENT COMPARISON
With a startup allow from the Commonwealth Fund (later supplemented by a sizable grant from NIAAA), we set out within February 1981 to conduct a study that would change the setting and examine the give somebody the third degree of alcoholism treatment efficacy in places of work, where on earth key decision were human being made daily that be shaping the treatment system. In doing so, we had two more goals contained by mind.
First, we considered it essential to try to advance the methodology of research surrounded by the EAP field, so we granted that the study would have to be a randomized controlled trial. It seem to us that a condition officially designated a disease by the American Psychiatric Association (in the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised, 1987), among other medical professional associations, ought to be studied using state-of-the-art research methodology for comparing alternative therapy. Randomized controlled trials are accepted as the "gold ingots standard" in studies of medical interventions; they assign patients to alternative treatments strictly on the reason of chance. Because disorganized assignment to treatment avoids the problem of human choice (by patients, clinicians, and/or researchers), it helps avoid screening bias, so that the groups being compared surrounded by the study are as similar as possible in every respect past being exposed to the treatment. Thus, differences observed during the course of the trial in response to different treatments can more confidently be attributed to the treatment itself, a bit than to differences participants brought near them into the study (for example, in motivation, in severity of impairment, or in other hard-to-measure predispositions that might affect the success of the treatment). Particularly surrounded by the case of behavioral disorders such as alcohol swearing, the patient's motivation is such a powerful influence on the outcome of treatment--and so difficult to measure--that study designs that do not use controls or randomization can never satisfactorily deal beside selection bias.
Second, within line near the study by Edwards and colleagues (1977), it seemed key to try to push the treatment efficacy question as far as we could, within search of something that would approximate an powerful minimum treatment package for problem-drinking workers. Other investigators be studying the effects of removing the overnight stay from the standard inpatient protocol; our goal be to compare treatments that were more widely spaced along a continuum of intensity, expense, and intrusiveness into body' lives.
Study Design
The study was base in a big manufacturing plant (10,000 employees) located within New England. We randomly assigned a series of just this minute identified alcohol-abusing clients of the plant's EAP to three alternative alcoholism rehabilitation regimens. The first alternative began next to a roughly 3-week period of mandatory inpatient rehabilitation in services that the EAP had be using for years. The second alternative mandated one and only that the employee attend Alcoholics Anonymous (AA) meeting; AA was the principal alternative to hospitalization that the EAP have available at the time. The third alternative, developed explicitly for purposes of the study, offered subjects a choice among treatments, with nondirective warning from the EAP administrators.
During a year of EAP-supervised probation, and through a second followup year, other inpatient treatment was available to study subjects who needed it. The assessment of need could be the subject's own or that of the EAP staff, base on the judgment that the subject be in sufficient trouble beside his or her drinking, after the randomly assigned referral, to place his or her career in jeopardy. This be necessary to ensure that taking part in the study would mean no extra risk to employees who enrol.
Thus, the study compared three distinct initial referral strategies, each next to a hospital backup if needed. All three strategies included AA as an integral component or option, so the study be, in effect, examining alternative pathway into AA. Yet the three strategies were fundamentally different surrounded by their underlying philosophies, in their costs, and in the manner and scope in which they intruded into patients' lives.
We compared the three treatments on various outcome measures collected over a 2-year period following the intake interview. For conceptual and analytic simplicity, the sundry outcome measures were collapsed into two leading categories of treatment nouns: job dramatization indicators and indicators related to continued drinking and other drug use. The study is represented schematically in Figure 1.
Recruitment, Eligibility, and Randomization
Participants were recruit for the study as they entered the EAP next to an alcohol problem that was interfering near their work. To be eligible, an EAP client was required (1) to be a bright case (without prior EAP contact), (2) to present with alcohol assault as the primary manifestation of problems, and (3) to fall in a gray zone where the company or confederation EAP administrators be uncertain whether hospitalization be the appropriate treatment. Formal eligibility criteria were negotiate in finance by the research and program staffs and were applied to the case-by-case assessment of whether a trial EAP client was any in serious satisfactory danger (medically or psychologically) to require direct hospitalization or well adequate to be a clear candidate for nonhospital treatment alone.
Between February 1, 1982 and June 30, 1987, every a moment ago identified alcohol-abusing client of the host EAP was screen for eligibility--371 clients in adjectives. Of those, 128 (35 percent) were ruled ineligible; the remaining 243 (65 percent) be escorted by the EAP staff to a study interviewer, who outlined the purposes, procedures, and sponsorship of the research project; explained mechanics of the randomization and study protocol; and stressed that enrollment was entirely voluntary. The interviewer discussed alternatives to contribution; possible risks and benefits; assurances of confidentiality; plans to interview a spouse or others close to the subject, and a job supervisor; and plans to examine company and hospital documents. An alcohol breath test be administered at this time to ascertain eligibility, assess competence to give informed consent, and enhance the reliability of self-reported facts.
Altogether, 227 subjects (94 percent of all eligible subjects) consented to join. Participants were placed at all over the place in one of the three initial rehabilitation strategies. Of the 227 subjects, 73 be assigned to the "hospital" group and were required to receive inpatient rehabilitation of approximately 3 weeks' duration. The average length of stay of subjects at the 10 participating hospitals be 23 days, and ranged from 10 to 37 days. Two inpatient services accounted for 86 percent of hospital assignments. Eighty-three subjects were assigned initially to the "compulsory AA-only" group. These subjects be referred and, if they wished, escorted directly to a local talks of AA. EAP counselors advised them to verbs attending the meetings on a each day basis sooner, to attend no less than three times a week, and to assert this involvement for at least 1 year. From the outset, the AA-only subjects be treated according to policies and procedures identical beside those applied to subjects in the hospital group after discharge from the inpatient setting. During a year's probation, subjects in both groups be monitored by the EAP, expected to remain sober at work, and expected to submit weekly listings of AA meetings attended. Seventy-one subjects made up the "choice" group: 29 elected hospitalization within a total of five different hospitals (average length of stay was 24.5 days, and range from 9 to 48 days); 33 chose AA; 3 chose outpatient psychotherapy (with a social worker, a psychiatrist, and a marriage counselor); and 6 opt for no formal treatment or help at adjectives.

Protection of Subjects
Five specific mechanisms be put in place to protect participating human resources. First and foremost, confidentiality of individual participants be scrupulously maintained throughout the course of the study, and, as an extra precaution, a Federal writ of confidentiality be obtained to shield the research files from subpoena. Second, taking part was other voluntary and fully informed; employees be remined at the beginning of respectively interview that they were free to rebuff to answer any questions, to closing stages the interview at any point, and to withdraw from the study at any time. Third, specific provisions be established to ensure that both job and treatment status be unaffected by taking part in the study. The re-treatment route was established to protected employees another unsystematic to save their job, should they relapse after the randomly assigned treatment. Fourth, the exclusion criteria be designed to satisfy the primary ethical prerequisite to any randomized trial--that random assignment be applied single in situations where on earth it is unclear which treatment alternative will be most significant. Fifth, stopping rules and a periodic review be instituted to provide for the cessation or modification of the trial as soon as a clear pattern emerge indicating that one of the treatments was significantly superior or inferior to one or both of the other treatments. [TABULAR DATA OMITTED]
Interviews and Data Collection
The rudimentary approach and findings of the study have be published elsewhere (Walsh et al. 1991a). Subjects were followed for 2 years from intake and be interviewed six more times (at months 1, 3, 6, 12, 18, and 24). Three interviews each, at intake and at the 1- and 2-year followups, be scheduled near job supervisors, and near spouses or others close to the subject, when available.
We divided outcome variables into two domains: job related and alcohol and other drug related. In both instances we specified a primary indicator (i.e., the "most impressive" indicator of outcome). The primary indicator of job outcome be involuntary termination from the company for unsatisfactory job show. Secondary indicators of job outcome, from interviews next to subjects, included problems with supervisors, alert notices, drinking on the livelihood, job accident, other accidents, and alcohol-related absenteeism. Other indicators of living outcome came from interviews beside supervisors and from computerized absenteeism tapes. The primary indicator of drinking-related outcome be referral for supplementary inpatient treatment. Secondary indicators of drinking outcome, all from self-reports, included any drinking, number of drinking days, average number of each day drinks, drunkenness, binges, blackouts, cocaine use, and scores on the Iowa Stages Index(1) and the Rand Behavioral Index.(2)
Major Findings
Table 1 list important descriptive characteristics of the 227 subjects at the time they be enrolled within the study, before the treatment begin. It shows that participants surrounded by the study were drinking heavily and experiencing heaps alcohol-related problems. The table divides the 227 subjects into the three treatment groups to which they were assigned, and indicates that the randomization worked: at intake the three groups be virtually identical.
After 2 years of followup in that were still no significant differences between the groups on the primary situation outcome: time to being fired from the company for unsound performance (Figure 2). All three treatment groups showed substantial and sustained upsurge in adjectives aspects of job functioning that we be able to document. Fewer than 15 percent of the example subjects were reporting any career problems at the 24-month followup, and 76 percent of supervisors interviewed at 24 months rated subjects' chore performance "worthy" (42 percent) or "excellent" (34 percent). Proportions of subjects with opening warning notice dropped from 33 percent at intake to under 2 percent at months 3 and 6, and stayed below 5 percent at each followup thereafter. On none of our 12 living outcomes did we find any significant differences between the three groups at any of the followup points.
However, on many of the indicators of drinking and other drug use, we did find statistically significant differences among the three groups. In nearly all instances, the hospital group experienced the fewest problems, and the compulsory AA-only group did smallest well. Figure 3 tracks individuals through the 2 years of followup and computes the cumulative proportions in respectively of the groups that were competent to complete the 2 years without ever relapsing to drinking. Among the 200 subjects followed by interview, 46 (23 percent of the 200 followed) reported at respectively of the five followup intervals (months 3, 6, 12, 18, and 24) that they had not have any alcohol to drink in the period since the previous interview. The hospital group be significantly more likely to include continuous abstainers (37 percent versus 16 percent for the AA-only group, p = 0.005.(3))
The proportions in respectively group who reported an unbroken record of "sobriety" (that is, no episodes of intoxication or drunkenness) at any followup (n = 67) also revealed statistically significant differences between the treatment groups (Figure 4). These facts include respondents who were abstaining from alcohol, as ably as those who reported drinking, but not to intoxication. Again, the hospital group had significantly lower rates of relapse to intoxication than did any of the other groups.
Supplementary Hospital Treatment and Relative Costs.
As mentioned previously, the study protocol included a provision for referring subjects for supplementary hospitalization if there be convincing evidence that they were drinking again and that the drinking be jeopardizing their jobs. Figure 5 compares the three groups surrounded by terms of percentage of member hospitalized for re-treatment and time elapsed until re-treatment. Of the 227 randomized subjects, 96 (42 percent) were hospitalized for treatment supplementation: 23 percent (17 of 73) of the hospital group, 38 percent (27 of 71) of the choice group, and 63 percent (52 of 83) of the compulsory AA-only group. These differences are importantly significant (p = 0.0001), again favoring initial hospitalization as the more effective treatment strategy.
We estimated aggregate inpatient treatment costs for the three groups, taking into side the initial hospitalization and all subsequent days of hospital treatment over the 2 years of followup. Even though the initial AA referral be free, the AA-only group had much better re-treatment rates. Compared with body randomized to the hospital, the AA-only group averaged $1,200 less per entity, a savings of basically 10 percent. The average cost for the choice group was almost similar with that for the AA-only group.
Other Drugs and Group Outcomes.
The compulsory AA-only group fare least in good health overall. In addition, although their numbers be small, patients who were abuse cocaine, together with alcohol, did especially poorly within the AA-only arm of the study. Cocaine use in the previous 6 months was reported at intake by 90 subjects (39.6 percent of the 227 randomized subjects). Of the 200 problem drinkers followed for 2 years, 78 (39 percent) reported cocaine use at intake, and these subjects be in substantially more trouble beside their drinking than were nonusers of cocaine (Walsh et al. 1991a).
When we examined outcomes by assignment for those 78 cocaine users, the 22 placed in the hospital group were
* significantly more feasible, at every
followup, to be abstaining from alcohol
than cocaine users randomized to
either of the other groups
* smaller quantity likely to report episodes of drunkenness
* smaller amount impaired on the Iowa and Rand
scales at 3 and 6 months.
The 30 cocaine users referred to AA singular were experiencing the most problems on these measures, and they be the most likely, at every followup, to report continued use of cocaine.
The Role of AA in the Recovery Process.
At the 1-month followup, subjects in the hospital group reported significantly more AA attendance: 77 percent be attending daily, compared near 7 percent and 36 percent of the AA-only and choice groups, respectively; 23 percent were attending from one to six times a week, compared next to 87 percent and 55 percent for AA-only and choice groups, respectively. Hospital group subjects were significantly more probable to report that AA was "incredibly helpful" (62 percent, compared near 28 percent of AA only and 32 percent of choice) and that have they not been required to turn to AA, they would have attended anyway, at least possible twice a week (69 percent of hospital, 38 percent of AA only, and 53 percent of choice).
By the 1-year followup, 77 percent of those within the hospital group, 72 percent of those in the AA-only group, and 66 percent of those contained by the choice group said they were still regularly attending AA. Fewer subjects said they be attending three or more meetings on average per week: 38 percent (hospital), 43 percent (AA only), and 28 percent (choice). These differences be not significant.
At both the 1- and 2-year followups, having attended AA meeting at all contained by the prior 6 months and frequency of attendance were significantly and inversely associated near drinking. Overall, 48 percent of AA attendees, compared with 66 percent of nonattendees, reported any drinking at 1 year; at 2 years, the comparable proportions be 49 percent and 81 percent. In terms of frequency of AA attendance, 75 percent of those who attended no AA meeting reported any drinking at 1 year, while only 38 percent of those who be attending three or more meetings a week reported any drinking; at 2 years, the comparable proportions be 77 percent and 39 percent. These findings suggest that a partial explanation of the higher nouns rates among the hospital group is that the hospital may have done a more forceful job of introducing AA and breaking down barrier and resistance to regular and ongoing AA attendance than did the other two treatment alternatives.
Discussion
Employees who were contained by serious trouble with alcohol showed significant amendment in drinking behavior and available job adjustment during the months immediately following an intervention to confront alcohol rough up that was intruding on their work. At the exit interview 2 years after intake, 41 percent (82 of 200 followed) said they be abstaining entirely from alcohol, and 23 percent (46 subjects) had reported continuous economy at each of five interim checkpoints.
At the cease of the 2 years, the average daily volume of alcohol for the preview of 200 workers had dropped from 6.3 to 1.5 drinks, and average number of drinking days in the month previously the interview had dropped from 19.8 to 3.1. The proportion classified as "distinctly alcoholic" on the Rand Behavioral Index had dropped from 75 percent to 11 percent, and the proportion reporting any binge drinking have dropped from 23 percent to 6 percent. These results compare favorably with published studies of alcohol treatment programs. Self-reported penny-pinching is, of course, somewhat suspect, but our findings are supported by the reality that the supervisors and spouses of self-reported abstainers confirmed their accounts in 90 percent of cases for which we have background. Owing to missing interviews, these confirmations represent 85 percent of all continuous abstainers.
Similarly, commission problems diminished markedly, and, despite a tendency to regress, never returned to preintervention level. Proportions of subjects reporting various problems on the employment ranged from 12 percent to 35 percent at intake and dropped to below 12 percent on adjectives indicators at 3 months. The rates rose gradually thereafter but never again exceeded 12 percent on any mission problem, even a full 2 years after intake.
To what extent the improvement reflect the immediate effect of individual enrolled within an EAP (perhaps creating a "moment of truth" to counter a habit of denial), the ongoing pressure of charge leverage, features of the three interventions themselves, or other combinations of forces, cannot be fully extrapolated from this study. It was designed not to unravel whether and how an EAP works but to compare three distinct initial referral commonly recommended by EAPs.
IMPLICATIONS AND RECOMMENDATIONS
From the standpoint of a company or union counselor, or a clinician advise patients, our findings argue for hospitalizing problem drinkers who are also in trouble near cocaine or other drugs. For the remaining group of problem drinkers who have fair job stability and no serious medical requirements, an initial referral to AA (especially one with an factor of choice) is the least costly route, but it is not without risk. Employees sent singular to AA will be more likely to hold their drinking problems resurface. Opting for the less costly intervention may be reorganized for the longer term if the money save is spent in identify and referring more employees near problems or if the availability of AA alone as an option encourage more employees to desire the company's help. But if AA alone is offered (or mandated) as a referral, our study shows that close monitoring is essential, because a few employees will experience serious relapses contained by the first 6 months.
Our study raises tons questions that require further research. Four stand out. First, alternatives to the hospital, bar just AA, stipulation to be evaluated in controlled intervention trials. Structured outpatient programs (including light of day or evening treatment), case paperwork techniques, and different matching strategies might manufacture it safer to reserve inpatient treatment as a last resort, but these possibilities, frequent of which have come into prominence since this study be launched, remain to be tested in systematic research.
Second, alternative relapse prevention strategies have need of to be compared in well-designed trials. Our results demonstrate a guide that other studies have repeatedly shown: relapse is completely common during the first 6 months after treatment. Therefore, more important approaches in the workplace for supporting human resources during that period of giant vulnerability in initial reclamation might make an celebrated difference in long-term nouns rates.
Third, we need thrifty investigations of opportunities for more effectual identification of incipient problems and for primary prevention. It may resourcefully be that modifiable factors exist contained by the organization of the workplace that in truth cause personnel to develop drinking problems or that accelerate the nouns of problems that could have be delayed or reversed. We know little at this point about the norm and forces within the workplace that may engender or exacerbate the risk of developing a serious problem next to alcohol. Certainly it is clear that the participants surrounded by our study were within considerable trouble with alcohol; near is every reason to believe that tons opportunities for before intervention were missed or overlooked (see Walsh et al. 1992).
Fourth, the results of this study may not be generalizable beyond the token of mostly white, employed males whose jobs be on the line because of their drinking. Similar studies are needed among other sample of workers.
Like all studies, this one have limitations that should be borne in mind. One cutting that has occasion discussion since the initial reports were published is the possibility that near may have be a bias in the referral for supplementary treatment, despite our efforts to intrude and monitor the application of standardized criteria. It is conceivable that the EAP administrators would own been smaller amount inclined to hospitalize an employee who have recently completed a course of inpatient treatment than an hand who had not. Conversely, it is possible that an member of staff who had already be hospitalized for drinking might be less reluctant to return to the hospital than would an hand who had on the other hand to cross that threshold. We conducted a number of analyses to verbs for such biases and found no statistically significant evidence that different criteria were applied to the three groups surrounded by decisions to recommend supplementary hospital treatment. However, the numbers be small enough and the analyses complex plenty that we cannot rule out all possibility that near was a bias. If at hand was one, it raise concern about the stress of re-treatment as an outcome measure. However, it would otherwise not alter the results of the trial and would not progress the finding, based on our analysis of drinking outcomes, that the hospital treatment be more effective as an initial strategy.
Questions own arisen, too, about why change in assignment performance come across not to have accompany changes contained by drinking as closely as might have be expected. It may be that our measures of job implementation were not polite enough to takeover subtle changes. Also, because the rates of profession problems declined for adjectives groups, we may not have have the statistical power to detect differences. Finally, because the company was monitoring these EAP clients closely, as adjectives in the re-treatment information, it may be that supervisors intervened before situation performance problems resurfaced among these recovering body.
For future research on alcohol problems surrounded by the context of work, this study demonstrates that tightly controlled studies can be carried out within employment settings. It confirms that, next to care, even a design as demanding as a randomized controlled trial can be implement in a track that is adjectives to organizational decision maker and to subjects themselves. The study also underscores the reality that worksite researchers may have a special dominance in their proficiency to maintain a taster through time, an issue that has habitually plagued clinically based and community-based substance misuse research.
(1) The Iowa Stages Index measures the intensity of current use of alcohol. It incorporates life problems to which drinking have contributed; drinking to cope with personal ambience; preoccupation with drinking; and loss of control over the amount consumed when drinking. Respondents are stratified according to the number of times they qualify on any one of these scales and thus are classified along a continuum of "stages" from "nonalcoholic" to "very-late-stage alcoholic."
(2) The Rand Behavioral Index measures the extent of drinking. The average behavior-impairment chalk up summarizes responses to a series of questions and
indicates the overall severity of a drinking problem. Scores field from 0 to 60, with 0 anyone least severe and 60 human being most severe.
