The community reinforcement approach to the treatment of substance use disorders.

Empirical support is presented for the Community Reinforcement Approach (CRA), a broad-spectrum cognitive-behavioral treatment for substance use disorders. At the core of CRA is the belief that an individual's environment can play a powerful role in encouraging or discouraging drinking and drug use. Consequently, it attempts to rearrange contingencies so that sober behavior is more rewarding than substance-abusing behavior. Originally tested in the early 1970s with a small sample of alcohol-dependent inpatients, it has repeatedly proven to be successful over the years with larger, diverse populations. Empirical backing is also presented for a new variant of CRA that works through family members to engage treatment-resistant individuals into substance abuse treatment.

Bleak and hopeless no more. Engagement Of reluctant substance-abusing runaway youth and their families.

Runaway/homeless shelters document high levels of substance abuse among runaway youth, at least double that of school youth. These youth present a constellation of problems and research suggests that this population may be unique in the range and intensity of associated problems. Most studies to date have collected self-report data on these youth; virtually no research has examined treatment effectiveness with the population. Given the void of treatment outcome research with these youths, there is need for identifying potent interventions. Given that issues of engagement and retention must assume prominence in the development of new treatments, this article presents a family-based treatment engagement strategy successfully employed with a sample of substance-abusing youth staying in a southwestern shelter. Youth and primary caretakers are engaged separately by the therapist utilizing motivating factors appropriate to context of the families' lives and to the developmental position of the client.

Engaging the unmotivated in treatment for alcohol problems: a comparison of three strategies for intervention through family members.

In a randomized clinical trial, 130 concerned significant others (CSOs) were offered 1 of 3 different counseling approaches: (a) an Al-Anon facilitation therapy designed to encourage involvement in the 12-step program, (b) a Johnson Institute intervention to prepare for a confrontational family meeting, or (c) a community reinforcement and family training (CRAFT) approach teaching behavior change skills to use at home. All were manual-guided, with 12 hr of contact. Follow-up interviews continued for 12 months, with 94% completed. The CRAFT approach was more effective in engaging initially unmotivated problem drinkers in treatment (64%) as compared with the more commonly practiced Al-Anon (13%) and Johnson interventions (30%). Two previously reported aspects of the Johnson intervention were replicated: that most CSOs decide not to go through with the family confrontation (70% in this study) and that among those who do, most (75%) succeed in getting the drinker into treatment. All 3 approaches were associated with similar improvement in CSO functioning and relationship quality. Overall treatment engagement rates were higher for CSOs who were parents than for spouses. On average, treatment engagement occurred after 4 to 6 sessions.

The community-reinforcement approach.

The community-reinforcement approach (CRA) is an alcoholism treatment approach that aims to achieve abstinence by eliminating positive reinforcement for drinking and enhancing positive reinforcement for sobriety. CRA integrates several treatment components, including building the client's motivation to quit drinking, helping the client initiate sobriety, analyzing the client's drinking pattern, increasing positive reinforcement, learning new coping behaviors, and involving significant others in the recovery process. These components can be adjusted to the individual client's needs to achieve optimal treatment outcome. In addition, treatment outcome can be influenced by factors such as therapist style and initial treatment intensity. Several studies have provided evidence for CRA's effectiveness in achieving abstinence. Furthermore, CRA has been successfully integrated with a variety of other treatment approaches, such as family therapy and motivational interviewing, and has been tested in the treatment of other drug abuse.

Community reinforcement and family training (CRAFT): engaging unmotivated drug users in treatment.

Although motivation for drug abuse treatment is a substantial problem, unilateral intervention through concerned significant others (CSOs) represents a promising method for engaging unmotivated individuals. The Community Reinforcement and Family Training (CRAFT) program, based on principles of reinforcement was developed for this specific purpose. In Phase I, CSOs received the CRAFT intervention, whereby they were taught skills for modifying a loved one's drug-using behavior and for enhancing treatment engagement. CSOs were evaluated at 3 and 6 months. In Phase II, engaged drug users received treatment using the Community Reinforcement Approach (CRA). A total of 62 CSOs participated in this evaluation of the effectiveness of CRAFT. CSOs completed, on average, 87% of offered treatment sessions. During the 6-month study period, 74% succeeded in engaging their resistant loved one in treatment. Reported abstinence both from illicit drugs and alcohol increased significantly for drug users engaged in treatment, but not for unengaged cases. All CSOs showed significant reduction in depression, anxiety, anger, and physical symptoms, with average scores dropping into the normal range on all measures. CRAFT provides a promising alternative to confrontational and detachment approaches in counseling CSOs to help their loved ones.

The community reinforcement approach with homeless alcohol-dependent individuals.

Homeless alcohol-dependent individuals were randomly assigned to receive either a behavioral intervention (i.e., the Community Reinforcement Approach [CRA]) or the standard treatment (STD) at a large day shelter. Ninety-one men and 15 women participated. The majority of participants were White (64%), but both Hispanic (19%) and Native American (13%) individuals were represented as well. Overall, the decline in drinking levels from intake through follow-ups was significant. As predicted, CRA participants significantly outperformed STD group members on drinking measures across the 5 follow-ups, which ranged from 2 months to 1 year after intake. Both conditions showed marked improvement in employment and housing stability.

Are reconstructed self-reports of drinking reliable?

When follow-up interviews are missed, researchers sometimes try to reconstruct the data that would have been obtained by asking clients to recall the missed interval when they are interviewed at a later point. Are such data reliable? The reliability of remote reconstruction was estimated by asking 57 participants in a clinical trial to recall their drinking for the 12-month follow-up interval when interviewed, on average, 33 weeks later. These reports were obtained after delays averaging 231 days. These reconstructed reports were compared with the same clients' self-reports obtained during the 12-month interview. Reconstructed data were found to be reasonably accurate estimates of clients' reports at the time of original interview on global alcohol use variables including percentage of drinking days and total volume of consumption. No systematic bias was found for over-reporting or under-reporting at the point of reconstruction. However, on some variables (e.g. total drinks consumed), clients on average reported more drinking at the reconstruction period than during the initial interview. Discrepancies between initial and reconstructed reports were found to be unrelated to the length of delay in the second interview or to client characteristics.

Intramuscular head and neck myxoma: report of a case and review of the literature.

Intramuscular myxoma of the head and neck is a rare lesion with only six cases documented in the literature. The tumor demonstrates a benign clinical course without a tendency to recur and is occasionally associated with fibrous dysplasia. It thus deserves to be considered in a separate class from other soft tissue myxomas. The seventh case of a head and neck intramuscular myxoma is presented and the clinical, pathological, and CT characteristics of this tumor are reviewed.

Combined fluoride, school-based program in a fluoride-deficient area: results of an 11-year study.

In 1972, a school-based fluoride program was initiated in elementary schools in Nelson County, VA, a fluoride-deficient area. For 11 years, participating children ingested daily in school a 1-mgm fluoride tablet and rinsed weekly with a .2% sodium fluoride solution. They also received fluoride dentifrice and toothbrushes for home use. The program was extended into junior high school in 1978 and into high school in 1980. In 1983, dental examinations of children aged 6 to 17 years, who had continuously participated in the program for 1 to 11 years depending on school grade, showed a mean prevalence of 3.12 DMFS, which was 65% lower than the corresponding score of 9.02 DMFS for children of the same ages at the baseline examinations. The preventive program inhibited decay in all types of surfaces: 54% in occlusal surfaces; 59% in buccolingual surfaces; and 90% in mesiodistal surfaces.

Prevalence of dental caries and dental fluorosis in areas with negligible, optimal, and above-optimal fluoride concentrations in drinking water.

The prevalence of dental caries and dental fluorosis was assessed in 1,123 children aged 8 to 16 years who were lifelong residents of areas with negligible, optimal, and above-optimal concentrations of natural fluoride in drinking water. Caries prevalence in the optimal fluoride area was 38.1% lower than it was in the negligible fluoride area, and, in the higher-than-optimal fluoride areas, even greater caries protection was evident. Caries protection was compromised in children with severe fluorosis. Findings do not support the contention that definite increases in the prevalence of fluorosis are occurring in communities with negligible and optimal water-fluoride concentrations because of increased total fluoride consumption from various sources.

Eight-year evaluation of a combined fluoride program in a nonfluoride area.

The purpose of this study is to measure the long-term effects of a combination of self-applied fluoride methods among schoolchildren living in a rural area with low concentrations of fluoride in drinking water. Participating children rinse weekly with a 0.2% sodium fluoride solution and ingest daily a 1-mg fluoride tablet in school under supervision of their teachers, and received fluoride toothpaste and toothbrushes for use at home. In 1980, dental examinations of children ages 6-14, who had continuously participated in the program for 1 to 8 years, depending on their school grade, had an overall mean caries prevalence of 3.22 DMFS, 49% lower than the corresponding mean score of 6.31 DMFS for children of the same ages at the baseline examination. The preventive program inhibited decay in all types of tooth surfaces: 37% in occlusal, 41% in buccolingual, and a striking 86% in mesiodistal. At each succeeding follow-up survey, benefits have continued to improve; the reductions in caries prevalence were 18% after 2 years, 35% after 4 years, 45% after 6 years, and 49% after 8 years. Findings in approximal tooth surfaces have also continued to improve as the length of the program has increased; reductions in caries in mesiodistal surfaces were 32%, 69%, 85%, and 86% after 2,4,6, and 8 years, respectively. Internal analyses of data indicate that the decline in dental caries prevalence resulted from the fluoride program and not from an unexplained natural decline in caries prevalence. The self-applied combined fluoride regimen used in this program has been shown to produce a pronounced anticaries effect.

A new method for assessing the prevalence of dental fluorosis--the Tooth Surface Index of Fluorosis.

A new index for measuring the prevalence of dental fluorosis, the Tooth Surface Index of Fluorosis (TSIF), was used to assess the condition in the permanent teeth of 807 children, aged 8 to 16, who had resided all their lives in one of seven Illinois communities with an optimal concentration of fluoride in its water or with 2, 3, or 4 times the optimal concentration. Fluorosis was absent in 84.5% of all tooth surfaces examined in the community with optimal fluoride. In contract, only 31.9% of tooth surfaces had no fluorosis in the community with 4-times the optimal fluoride level. In the optimal fluoride area, 79% of facial surfaces of maxillary anterior teeth, which are esthetically conspicuous, had no fluorosis, whereas only 15.8% of these surfaces in the 4-times optimal area were unaffected. The percentages of all tooth surfaces affected by fluorosis characterized by staining, pitting, or both were 1%, 8%, 19%, and 38%, respectively, in communities with 1-, 2-, 3-, and 4- times optimal fluoride. Differences in fluorosis based on maximum score for all tooth surfaces in a child were statistically significant (an extended chi 2 statistic) among all communities. First molars and incisors in children 8 to 10 years old were affected by more fluorosis than were the same teeth in children 13 to 16 years old. These teeth had been erupted for about 5 years longer in the older age group. The difference might result from abrasion or remineralization of these teeth in the older children or from greater consumption of fluoride by the younger children during tooth development.(ABSTRACT TRUNCATED AT 250 WORDS)

Prevalence of dental caries and dental fluorosis in areas with optimal and above-optimal water fluoride concentrations.

The prevalence of dental caries and dental fluorosis was assessed among 807 schoolchildren in four areas of Illinois where the respective water supplies contained natural fluoride at concentrations of 1, 2, 3, and 4 times the recommended optimal for the geographic area. Mean caries scores in all three above-optimal fluoride areas were significantly lower than in the optimal area. The prevalence of dental fluorosis was characteristically low in the optimal fluoride area. Substantial increases in fluorosis occurred in the above-optimal fluoride areas, with the condition being most pronounced in the 4-times optimal area.

A program self-administered fluorides in a rural school system.

In 1972, a self-administered fluoride program was initiated in Nelson County, VA, a fluoride-deficient area. Children in elementary school (grades K-6) ingest daily a 1-mg fluoride tablet, rinse weekly with 0.2% NaF solution and receive fluoride dentifrice for home use. In 1978, dental examinations of elementary schoolchildren (ages 6-12) who had continuously participated in the program for 1 to 6 years showed a prevalence of 2.70 DMFS, 45% lower than the score of 4.89 DMFS for their cohorts at the baseline. The preventive program inhibited dental caries effectively in all types of surfaces, but the reduction in proximal surfaces of 85% is particularly striking. Findings of high school children (ages 13-17) in 1978, who had not participated in the elementary school program for 1-5 years, showed evidence of strong post-treatment effects. At each succeeding follow-up survey, benefits have continued to improve. For elementary school participants, benefits were 17.7% after 2 years, 35.3% after 4 years and 44.8% after 6 years. Weekly fluoride mouthrinsing and daily ingestion of a fluoride tablet are feasible school-based procedures for the prevention of dental caries. Combined with the use of a fluoride dentifrice at home, these procedures have a pronounced cariostatic effect.

Evaluation of a combination of self-administered fluoride procedures for the control of dental caries in a nonfluoride area: findings after four years.

Nearly all children who attend elementary school (grades K through 6) in a rural community have participated since 1972 in a school-based caries preventive program consisting of daily ingestion of a 1-mg fluoride tablet and weekly rinsing with a 0.2% sodium fluoride solution. 3they also regularly receive toothbrushes and a fluoride dentifrice for use at home. Examinations conducted after four years showed that the prevalence of dental caries among continuous participants, 7 through 12 years of age, was reduced by 35% compared with baseline findings; mean DMFS scores in 1972 and 1976 were 5.39 and 3.49, respectively. The preventive program inhibited decay in all three types of surfaces: approximal surfaces received about twice the relative protection against decay (70%) as buccolingual surfaces (34%) and more than three times as much as occlusal surfaces (22%). A comparison of estimates of four-year increments of decay taken from cross-sectional data at the baseline and actual increments from the 1972 and 1976 examinations showed that, for children ages 6 through 15, the incremental DMFS score was 41% lower during the period of the program than before its initiation. Findings in older children (ages 13 through 15) in 1976 who had stopped participation when they left elementary school at about age 12 showed evidence of strong posttreatment effects--as great as 31% fewer DMFS for 14-year-old children.
