Purpose: Over the past two decades, computerized and Internet-based interventions for the treatment of various health problems, including substance abuse, have been developed and used to resolve treatment-related issues. The purpose of this study is to review selected studies that conducted computerized and Internet-based psychosocial interventions for people with drug-use problems.

Methods: We used a PubMed search to identify relevant studies to our review based on the following inclusion criteria: 1) the study participants were drug users; 2) the Internet or computer technologies were used for the interventions; 3) the study used psychosocial interventions; and 4) meta-analysis and randomized controlled trial (RCT). In total, 12 studies (meta-analysis = 1, RCT = 11) were identified and included in this review. The RCTs extracted in this study were not included in the meta-analysis.

Results: The meta-analysis showed that studies targeting people with alcohol and/or drug-use disorders (n = 11) had a small effect size (d = 0.24). However, the effect size was considered heterogeneous. Most of the reviewed RCTs assessed either drug use or abstinence as primary outcome using such methods as self-report and urine test, and showed that intervention groups exhibited greater improvement in the drug use condition than the control groups. The effect sizes (d) ranged from 0.19 to 0.54. One study revealed that a computerized intervention was more cost effective if it was added to treatment as usual. Various interventions were designed to use behavioral therapy approaches, e.g., cognitive behavioral therapy, motivational interviewing, as well as face-to-face interventions. Treatment retention, adverse events, relationship with therapists and engagement in the treatment were assessed as secondary outcomes. These outcomes were equivalent or more effective for the intervention groups compared with the control groups.

Conclusions: Computerized and Internet-based psychosocial interventions for drug users have a small to medium effect on the reduction of drug use but are highly cost effectiveness. These types of interventions can contribute to the improvement of treatment environments where treatment resources are very limited or where there is a stigma attached to drug users, as is often the case in Japan.

This report describes the effect of a screening and brief intervention via the Internet (6-month Total health Management Program: TMP, a kind of life evolution program), for improvement of alcohol related problem in the workplace. At a certain company, 2,096 employees were screened.using AUDIT-C and CAGE via the Internet (electronic screening). From those screened, 17 risky drinkers were picked up. The classification of "risky drinker" was determined based on employees scoring over six points on AUDIT-C and over two points on_ AGE. These employees were then called to one-day practical seminar program (including the program of food education, music therapy, aro-atherapy, body conditioning etc.). After which, during 6 months, they were followed up via e-mail every month. After the 6-month follow up, their results of AUDIT-C were significantly decreased. Additionally, aside from the frequency of drinking at bedtime, maximum alcohol consumption per day was also significantly decreased. The Visual Analogue Scale for anxiety captured the initial screen and then again after follow-up was reduced significantly. Moreover, quality-of-life index for sleep and dinner were both significantly improved as well..These results suggest that the SBI (screening and brief intervention: TMP) is effective for reducing drinking behavior, can be used to effectively elevate quality of life.

In this study, we compared the efficacy of a group relapse prevention program using the cognitive behavioral therapy-based workbook, Serigaya Methamphetamine Relapse Prevention Program (SMARPP), between patients abusing the so-called "dappou drugs" (designer drug in Japan, and those abusing methamphetamine (MAP). Both groups participated in the SMARPP at the Center Hospital, National Center of Neurology and Psychiatry. Results showed that, no significant differences were found in the rates of participation in the program or self-reported frequency of drug or alcohol use between the patients abusing "dappou drugs" or MAP. However, patients using "dappou drugs" reported no significant increase in their confidence in their ability to resist the temptation to use drugs on the self- report drug abuse scales after the SMARPP intervention, while patients abusing MAP reported a significant positive difference in their ability to resist temptation. In addition, insight into substance abuse problems and motivation to participate in further treatment slightly declined in those using "dappou drugs," while there was a significant increase reported by the patients using MAP. These results suggested that the SMARPP might not be as effective for patients abusing "dappou drugs" as for those abusing MAP. The development of a relapse prevention program specifically designed for patients abusing "dappou drugs" is required.

Alcoholics have a high prevalence of nicotine dependence, and smoking is a major contributor to their high mortality. Three weeks after admission to an addiction center in Japan, 193 alcoholic men who were participating in an 11-week concurrent inpatient smoking cessation and alcohol abstinence programs filled out an anonymous self-report questionnaire regarding smoking and drinking, and 6 months after the completion of the programs, 83 patients were asked to respond to a mailed questionnaire about their smoking and drinking status. Of the 193 subjects, 73.3% were current smokers, but many were highly motivated in regard to both smoking cessation and alcohol abstinence. The subjects' scores on a 0 to 10 point scale for rating motivation and confidence in regard to smoking cessation and smoking urge were significantly correlated with each other and with their scores for motivation and confidence in regard to alcohol abstinence and drinking urge. Three weeks after admission, varenicline treatment was well-tolerated, and the varenicline group had a high rate of smoking cessation than the smoker group not treated with varenicline (67.7% vs. 44.6%, p = 0.012). Forty-six (55.4%) of the 83 subjects who were mailed the questionnaire responded, and the drinking category was 'totally abstinent' in 35 subjects (42.2%), and 'mostly abstinent' in another 4 subjects (4.8%). Seventeen (20.5%) of the 83 subjects were non-smokers before treatment, but after treatment, 23 (50.0%) of the 46 responders and 20 (51.3%) of the 'totally or mostly abstinent' 39 responders were total or almost non-smokers. The response rate of 'totally or mostly abstinent' was higher among the 17 non-smokers before treatment than among the 66 smokers before treatment (70.6% vs. 40.9%, p = 0.033), and the age-adjusted odds ratio (95% confidence interval) for the response of 'totally or mostly abstinent' was 3.30 (1.03-10.56) for the non-smokers before treatment (vs. the smokers before treatment). In conclusion, smoking status had a great impact on the drinking status of treatment-seeking alcoholic men, and smoking cessation should be recommended to smoking alcoholics.

The development of an effective treatment system for patients with addiction-related problems like substance abuse or pathological gambling is urgently needed. The purpose of this study was to clarify the therapeutic factors of the Tama Mental Health and Welfare Center Relapse Prevention Program (TAMARPP). The program is provided at the Tama Comprehensive Center for Mental Health and Welfare, which is operated publicly by the Tokyo Metropolitan Government. Seven personnel (3 clinical psychologists, 2 public health nurses, and 2 recovering counselors) searched the consultation records of 31 participants who had continued treatment longer than 1 year, and made a list of qualitative factors that may positively impact participant outcome. The following six factors were extracted: 1) a "no-blame" atmosphere that makes participants feel safe and free; 2) a mutual helping process that enables participants to empathize with one another; 3) an individual-centered approach that focuses on a participant's motivation to recover; 4) a psycho-educational process that establishes treatment goals; 5) a treatment goal that involves some type of social role; and 6) the referral of graduates to another long-term treatment program such as Narcotics Anonymous. Our results suggest the need of personnel to provide treatment as follows: 1) keep the circumstances safe; 2) use a method that matches the participant's motivation; 3) refer graduates to another in-depth treatment program; 4) emphasize the relationship between thinking, emotion, and behavior; and 5) improve the quality of life of the participant. The missions of our center, an official institution that runs such a program, are as follows: 1) to be the first place at which addicts seek aid during the early stage; 2) to cooperate with other facilities in order to provide social resources that support recovery; and 3) to support patients suffering from both addiction and comorbid psychiatric diseases.

Several studies have suggested that the norepinephrine transporter (NET) may play an important role in the pathogenesis of alcohol dependence. Therefore, in this study, we investigated whether the NET gene polymorphism is a susceptibility factor for alcohol dependence in 64 alcoholics and 73 healthy controls. In addition, we examined whether the combination of the NET and serotonin transporter genotypes are associated with alcohol dependence. The NET (1287G/A, -182T/C, and -3081A/T) and serotonin transporter (5-HTT3'UTR) genotypes were determined by the polymerase chain reaction (PCR)--restriction fragment length polymorphism (RFLP) method. No significant differences in genotype and allele frequencies of the NET and serotonin transporter gene polymorphisms were found between alcoholics and controls. The haplotype frequencies of the NET gene polymorphisms were not also significantly different between them. Furthermore, the combination of the NET and serotonin transporter genotypes had not significant effects on alcohol dependence. The present study suggests that the polymorphisms of 1287G/A, -182T/C and -3081A/T in NET gene are not.risk factors in alcohol dependence.

In psychiatric care practice, patients are often seen who have difficulty with their social lives due to protracted psychiatric symptoms despite years without drug abuse. The difficulty of dealing with such cases and the lack of preparedness of the legal system leave circumstantial care as the only option. Western.countries have recently begun using the name 'concurrent disorder' as a diagnosis for patients deemed unable to recover solely through such treatment for drug addiction, signifying the presence of both a substance use disorder (SUD) and a mental health disorder. Various assessment and intervention methods are being investigated, and many studies have been reported. Based on the hypothesis that Drug Addiction Rehabilitation Center (DARC) are partly involved in supporting those with psychotic concurrent disorders (PSCD) in Japan, we conducted a survey to clarify the actual support for PSCD patients at DARC and the challenges they face. Surveys were administered to DARC-related institutions all over Japan (44 governing organizations and 66 institutions). Complete responses from 86 full-time employees and 445 DARC users were analyzed. DARC users were divided into two groups: psychiatric concurrent disorders (PSCD group, n = 178) and those without such symptoms (SUD group, n = 267), with the PSCD group accounting for 40% of the DARC users surveyed. Compared to the SUD group, the PSCD group was significantly less satisfied with their lifestyle and interpersonal relations at the DARC and a significantly higher proportion of the PSCD group requested assistance in communicating with others. When employees were presented with a hypothetical PSCD case and asked what was needed to deal with it, some responses were, "an institution that can treat both drug addiction and other mental health disorders," "a psychiatric care institution that provides 24-hour care," and "sufficient manpower and training." In the future, a treatment system must be established based on public medical institutions with a dedicated PSCD program that can provide medical care under legal observation.

Programs for improving motivation to recover drug dependence were conducted in penal institutes in Japan. This study examined the effects of these programs, in order to increase their efficacy. Furthermore, relationship between increased motivation and prevention of recidivism was examined. The following programs had been conducted in penal institutions: (1) speed learning program using audio-visual aids, (2) meeting program (meet a experienced person in recover), in cooperation with DARC (Drug Addiction Rehabilitation Center), and (3) relapse prevention program. Participants were female inmates (N = 94) that had taken part in one of the programs. In order to examine the relationship between motivation for change and recidivism, the motivation for change score was assessed before and after the treatment program. Furthermore, a followed-up was conducted to assess recidivism after release. Results indicated that all the programs resulted in improvements in motivation for change. However, motivation for change resulting from none of the programs had any significant effect on recidivism. The objectives of the treatment programs were reached as expected, since motivation for change improved after the treatment However, it is suggested that to prevent recidivism, more effective treatment methods for improving motivation to change are required.

Marchiafava-Bignami disease is a rare alcohol-associated disorder. Clinical features include not only disturbed consciousness, dysarthria, tetraparesis, and astasia-abasia as initial symptom but also cognitive deficits and symptoms of interhemispheric disconnection as clinical outcomes. The clinical significance of cerebral microhemorrhage has been recognized in patients with cognitive deficits. We have recently examined the clinical significance of cerebral microhemorrhage in Marchiafava-Bignami disease and demonstrated that demented patients showed higher severity of cerebral microhemorrhage than patients with normal cognitive function. However, the relationship between callosal lesions and cerebral microhemorrhage in Marchiafava-Bignami disease has not been fully examined. The aim of the present study was to clarify the relationship between callosal lesions and cerebral microhemorrhage in Marchiafava-Bignami disease. For this purpose, we report four patients with Marchiafava-Bignami disease. All cases had a history of chronic alcohol abuse and symmetrical lesions in the corpus callosum. Clinical symptoms include not only coma, dysarthria, and astasia-abasia as initial symptom but also dementia as clinical outcomes. Susceptibility-weighted imaging showed asymmetrical hypointense areas in the multiple cortico-subcortical regions, indicating the presence of cerebral microhemorrhage. There were no apparent relationships between the extension of callosal lesion and the severity of cognitive deficits or cerebral microhemorrhage. Our present report indicates that cerebral microhemorrhage, an important. factor for the severity of dementia in Marchiafava-Bignami disease as clinical outcomes, is independent of the callosal lesion.

In 1983, Nei et al. reported that alcoholic chronic hepatitis (ACH)(chronic hepatitis induced tal area. Recently, the number of alcoholics patients diagnosed with ACH has been increased In this review, we discussed the characteristics of liver histopathology and blood chemistry of ACH patients. In ACH, pericellular fibrosis, ballooned hepatocytes and/or bridging fibrosis, and infiltration of mononuclear lymphocytes is decreased after 6 to 8 weeks of abstinence from results suggest that ACH could be one type of alcoholic liver disease. The precise mechanism by alcohol) as one type of alcoholic liver disease. Since then, it has been discussed whether alcohol abuse, suggesting that alcohol may play a role in the infiltration of mononuclear lym ACH is one type of alcoholic liver disease, because there could be infection of unknown hepatitis virus in alcoholics and it is not clear why mononuclear lymphocytes infiltrate into the porphocytes in portal region. After abstinence of alcohol, serum levels of AST, ALT, and γ-GTP in patients with ACH returned to normal as in other types of alcoholic liver disease such as alcoholic fatty liver, alcoholic fibrosis, alcoholic hepatitis and alcoholic liver cirrhosis. These results suggest that ACH could be one type of alcoholic liver disease. The precise mechanism of the infiltration of mononuclear lymphocytes into portal areas of ACH patients is not known. We propose that the reason for the infiltration of natural killer (T) cells into portal areas could be due to the influx of endotoxin into portal vein resulting from the increased permeability of gut induced by alcohol.
