RESUMO
AIM: Alcoholism is the most prevalent substance use disorder in Japan; the estimated number of patients and high-risk drinkers is in the millions. Although studies in the West have shown that cognitive behavioral therapy (CBT) is one of the most effective treatment strategies for alcoholic patients, there is a dearth of efficacy studies of CBT-based intervention for those patients in the non-Western setting. The aim of this study is to investigate the efficacy of a 12-session CBT-based relapse prevention program for Japanese alcoholic patients. METHODS: Forty-eight alcoholic patients (M = 36, F = 12) who were admitted to an addiction treatment unit were randomly allocated either to a 12-session relapse prevention (RP) program (n = 24) or a 12-session psychoeducation (PE) program (n = 24). Both treatment programs were conducted in a group format once a week for 12 weeks. Other aspects of inpatient treatment (group meetings, etc) were the same in both groups. Self-rating scales, which measure behavioral and cognitive coping, coping response, self-efficacy, and cognition of drinking, were administered at pretreatment, mid-treatment, and posttreatment periods. The proportion of participants who relapsed at 3 and 6 months after discharge was evaluated. RESULTS: Both RP and PE groups showed significant improvement in self-efficacy and cognition of drinking at posttreatment. However, there were no significant differences in the self-rating scales between both groups. In addition, there were no significant differences in relapse rate at 3 and 6 months after discharge between both groups. CONCLUSIONS: The 12-session CBT-based relapse prevention program and the psychoeducation program may be equally efficacious for alcoholic patients. Several factors that influenced the results are discussed.

AIM: This prospective, randomized, controlled, rater-blinded study investigated the effect of G protein-activated inwardly rectifying potassium (GIRK) channel inhibitor ifenprodil on alcohol use in patients with alcohol dependence. METHODS: The participants were 68 outpatients with alcohol dependence who were assigned to an ifenprodil group (administered 60 mg ifenprodil per day for 3 months) or control group (administered 600 mg ascorbic acid and calcium pantothenate per day for 3 months). The participants completed a questionnaire that included the frequency of alcohol drinking and presence of heavy drinking before the study period (time 1) and 3 months after the start of the study period (time 2). The alcohol use score was calculated using these two items. RESULTS: Valid data were obtained from 46 participants (25 in the ifenprodil group and 21 in the control group). The alcohol use score at time 2 in the ifenprodil group was significantly lower than that in the control group after adjusting for the score at time 1 and some covariates. The intention-to-treat analysis of multiply imputed datasets indicated similar results. Group differences in the frequency of alcohol drinking were significant in the multiply imputed datasets but not in 46 participants. The ifenprodil group had a significantly lower rate of heavy drinking at time 2 than the control group. CONCLUSIONS: This study found an inhibitory effect of ifenprodil on alcohol use in patients with alcohol dependence. The results support the hypothesis that GIRK channel inhibitors ameliorate alcohol dependence. TRIAL REGISTRY: This trial was registered in the UMIN clinical trial registry (UMIN000006347).

BACKGROUND: Relatively few hospitals can treat substance use disorder in Japan and the options for treatment are limited. Previous studies in the West have shown the effectiveness of brief intervention for substance use disorder. However, such treatment has not been sufficiently implemented in Japan. For this study, we developed brief intervention tools for substance use disorder, and conducted a pilot study to evaluate the efficacy of treatment. METHODS: Participants in this study were recruited from those admitted for substance use disorder in the addiction treatment unit of Tokyo Metropolitan Matsuzawa Hospital, and the recruitment period was from October 2013 through March 2014. The brief intervention consisted of one 30-min individual session. Four self-rating scales measuring motivation, relapse risk and self-efficacy were administered pre- and post-intervention: SOCRATES-8D, Stimulants Relapse Risk Scale, Drug Abuse Self-efficacy Scale and Visual Analogue Scale. RESULTS: Forty patients participated in this study. Subscale Scores at post-intervention that improved significantly compared to those at pre-intervention were Recognition (SOCRATES-8D); Total score and Anxiety and intention to use drug (Stimulants Relapse Risk Scale); Generalized self-efficacy (Drug Abuse Self-efficacy Scale); and Knowledge about drug abuse (Visual Analogue Scale). CONCLUSION: These results indicate that brief interventions may offer effective treatment for substance use disorder. A randomized controlled trial that contains an evaluation of abstinence rate in the follow-up period is needed to ascertain the efficacy of brief intervention for substance use disorder in Japan.

In Japan, many drug addiction rehabilitation centers (DARC) provide various types of recovery programs for drug addiction. The purpose of this study was to clarify the attitudes of DARC staff and users regarding job support programs. A nationwide questionnaire survey was conducted in 2009. The staff of 46 facilities and 606 users returned questionnaires. The results indicated that many (92.1%) users had work experience before entering the recovery programs provided by DARC and about half (49.3%) of the users reported being motivated to work. Although many DARC have established various job support programs, the users faced various levels of anxieties to get employed and 60.4% of the users expected to learn more detailed and concrete methods for finding a job. Through the DARC programs, the users gradually realize the significance of basic daily living skills such as maintaining their rhythm of life or neat and presentable appearance. And the more they get recovered the more they understand the significance of "self-care" and "interpersonal relationship skills". These findings indicate that job support programs for drug addicts should also focus on these recovery processes. More extensive job supports dealing with more practical issues and covering a wide variety of anxieties would be imperative.

OBJECTIVES: Methamphetamine (MAP) is one of the most commonly abused drugs in Japan. Japan has experienced three major epidemics of MAP abuse. The characteristics of abusers have changed between the second and third epidemics; however, few epidemical studies have investigated these changes. The purpose of this study is to describe the differences in the characteristics of MAP abusers between the second and third epidemics. METHODS: We surveyed the medical records of patients admitted to Tokyo Metropolitan Matsuzawa Hospital for MAP-related disorders between 1989 and 1993 (n=60; second epidemic group) and between 2004 and 2008 (n=119; third epidemic group). We compared patients' backgrounds and issues related to MAP abuse between the two groups. RESULTS: Compared to the second epidemic group, more abusers in the third epidemic group were similar to the general population of young people in terms of education level and criminal activity; were on welfare; had dependence syndrome; smoked MAP; and co-abused legal drugs. In contrast, abusers who exhibited antisocial tendencies and injected MAP were more likely to be in the second epidemic group. CONCLUSIONS: We confirmed changes in the characteristics of MAP abusers between two of the three epidemics of MAP abuse in Japan. These findings suggested that the change of environments from the second epidemics of MAP abuse to the third one influenced the characteristics of MAP-related disorders. So, it is necessary to provide accurate and updated knowledge about MAP for the drug prevention to young people, and the treatment of dependence syndrome will become more important in the future.

In Japan, the target mental disorders of preventive strategies for suicide had been limited to be mood disorder, but recently drug abuse are known to be significant as a cause of suicide because some researches has found the association between substance use disorder and suicidal behavior in Japan. However, the preventive plans for suicide of drug abusers has not been developed yet. In this study we would like to examine the risk factors of suicide ideation in Japanese drug abusers. We analyzed the data of 445 drug addicts from the Nationwide Research of Drug Addiction Rehabilitation Centers by Tokyo DARC and compared many variables including demographic factors, drug use status, family history, psychopathologies, treatment and daily life satisfactions between people with suicide ideations and without ideations. It was found that 182 cases (43.8%) had suicide ideations in a recent month, and that addicts who had suicide ideations had significantly shorter abstinence time, higher prevalence of victimized experiences before 15 years age, and more mental symptoms such as insomnia, depression, and psychotic symptoms, and more tendencies to use prescribed psychotropic drug than those without suicide ideation. These results suggested that to prevent suicide of drug abusers, we should pay attention to family histories, insomnia and abstinence periods, and help them recovery from psychological damages caused by childhood trauma without inappropriate medications.

BACKGROUND AND AIMS: The aims of present study are to clarify the clinical features of patients with benzodiazepine use disorder (BZsUD), and to examine the characteristics of psychiatric treatments which may cause BZsUD. METHODS: We conducted a medical chart and interview survey to 87 outpatients with benzodiazepine use disorder, who had consecutively visited the four hospitals, specialized in addiction problems, located in metropolitan area, during a month of December, 2011. RESULTS: Consequently, 88.5% of the patients with BZsUD reported to obtain BZs to be abused from general psychiatric clinics, and 83.9% contracted BZsUD in process of general psychiatric treatment. Among the patients who contracted BZsUD in process of psychiatric treatment, 43.8% were speculated to have the other substance-related disorders such as methamphetamine or alcohol-related disorder at start of the psychiatric treatment. Further, approximately 70% of them reported that surplus BZs were prescribed without consideration of storing drugs, and over 40% also reported that BZs were prescribed without a medical examination. CONCLUSIONS: The findings of the present study may let us to propose the following four measures to be taken for prevention of BZsUD: First, latent substance-related disorders should not be overlooked, second, short-acting and high-potency BZs should not be prescribed if possible, third, storing and abusing BZs should always be considered, and finally, BZs should be prescribed with a medical examination.

We investigated the differential influence of family dysfunction on alcohol and methamphetamine dependence in Japan using the Addiction Severity Index (ASI), a useful instrument that multilaterally measures the severity of substance dependence. The participants in this study were 321 male patients with alcohol dependence and 68 male patients with methamphetamine dependence. We conducted semi-structured interviews with each patient using the ASI, which is designed to assess problem severity in seven functional domains: Medical, Employment/Support, Alcohol use, Drug use, Legal, Family/Social relationships, and Psychiatric. In patients with alcohol dependence, bad relationships with parents, brothers and sisters, and friends in their lives were related to current severe psychiatric problems. Bad relationships with brothers and sisters and partners in their lives were related to current severe employment/support problems, and bad relationships with partners in their lives were related to current severe family/social problems. The current severity of psychiatric problems was related to the current severity of drug use and family/social problems in patients with alcohol dependence. Patients with methamphetamine dependence had difficulty developing good relationships with their father. Furthermore, the current severity of psychiatric problems was related to the current severity of medical, employment/support, and family/social problems in patients with methamphetamine dependence. The results of this study suggest that family dysfunction differentially affects alcohol and methamphetamine dependence. Additionally, family relationships may be particularly related to psychiatric problems in these patients, although the ASI was developed to independently evaluate each of seven problem areas.

The coexistence of methamphetamine use disorder (MUD) and psychotic disorder (PSD) is common in clinical settings. These cases are defined as methamphetamine concurrent disorder (MCD). It is often hard to decide which type of support is suitable for a MCD case; the one used for schizophrenics ("schizophrenia-support" model) or for drug addicts ("dependence-support" model). In the present study, we compare the courses of two MCD cases; one was supported using the "schizophrenia-support" model, and the other by the "dependence-support" model. These cases suggest that it is preferable to switch the models from one to the other, based on the severity of dependence. After stabilizing the patient's life through the use of at least three to six months of pharmacotherapy and psychiatric rehabilitation, we can recommend that the patient attend self-help meetings convenient for them. If the MCD patient has no risk of methamphetamine use, the hospital should play a major role to urge the health and the welfare facilities to support the patient. If the patient has some risk of relapse or criminal behavior, the legal system as well as medical and welfare facilities should play the major roles to present suitable services and to prepare an appropriate care-system.

OBJECTIVE: To develop and validate the Alcohol Relapse Risk Scale (ARRS) for Japanese alcohol-dependent individuals and to compare the features of relapse risk for alcohol-dependent individuals with those for stimulant abusers. METHODS: The ARRS is a multidimensional self-rating scale consisting of 32 items based on the Stimulant Relapse Risk Scale (SRRS). Two hundred eighteen inpatients and outpatients with a history of alcohol dependence (181 males and 36 females) were recruited, provided informed consent, and were administered the ARRS. The Visual Analog Scale (VAS) for alcohol craving, current state of drinking, and data on relapse within 1 month after the rating were used for validation. RESULTS: Exploratory factor analysis highlighted five factors: stimulus-induced vulnerability (SV), emotionality problems (EP), compulsivity for alcohol (CA), lack of negative expectancy for alcohol (NE), and positive expectancy for alcohol (PE). Cronbach's alpha coefficient for each of the subscales ranged from .55 to .90 and was .90 for the total ARRS, indicating their adequate internal consistency. SV, EP, CA, PE, and total ARRS were significantly correlated with the VAS and current drinking state, supporting their concurrent validity. SV and total ARRS were significantly correlated with relapse, suggesting that the ARRS is useful for predicting relapse risk in alcohol-dependent individuals, similar to the SRRS for stimulant abusers. Compared with stimulant abusers, alcohol-dependent individuals tended to express their desires related to relapse more honestly on the scales. CONCLUSIONS: The ARRS has multidimensional psychometric properties that are useful for assessing the various aspects of alcohol relapse risk.

Child abuse is known to correlate with drug abuse and interferes with recovery from substance-related disorders. To determine the prevalence and severity of child abuse among drug addicts, we conducted a nationwide cross-sectional survey of residents and outpatients at drug addiction rehabilitation centers (DARC) in Japan. A total of 445 participants gave informed consent and completed a self-reporting questionnaire. Sixty-eight percent of participants had experienced some kind of child abuse by the time they reached junior high school. The kinds of abuse experienced were physical (53.7%), psychological (60.4%), sexual (5.4%) abuse and neglect (24.5%). Comparison of female and male participants revealed that more female than male participants had experienced psychological (76.9% vs. 58.2%) and sexual (17.5% vs. 4.0%) abuse. Comparison of participants who had experienced some kind of child abuse ("Abused" group 68.3%) and those who had not experienced abuse ("Non-abused" group 24.3%) revealed that the "Abused" group was younger than the "Non-abused" group (35.7 SD9.0 vs. 39.7 SD10.8). Participants in the "Abused" group were found to have more severe psychological difficulties than those in the "Non-abused" group for the following: anxiety (73.0% vs. 61.1%), delusional atmosphere (48.0% vs. 28.7%), lack of energy (53.9% vs. 40.7%), ideas of persecution (48.7% vs. 29.6%), depression (62.2% vs. 43.5%) and suicidal ideation in the previous year (50.7% vs. 24.3%). The present results suggest that additional program that prepared to care the drug addicts who experienced child abuse and are experiencing suicidal ideation is needed. Furthermore, intervention for families with risk factors for child abuse should be developed in order to prevent the victim from suffering not only from post traumatic stress disorder but also from substance related disorders.

OBJECTIVE: To develop and validate a multidimensional measure of relapse risk for stimulants in Japanese drug abusers. METHODS: A Stimulant Relapse Risk Scale (SRRS) was developed based on the Marijuana Craving Questionnaire and a discussion among three psychiatrists. We created 48 items after confirming the items including a variety of relapse risk, such as craving (expectancy, compulsivity, etc.) and emotionality problems. One hundred inpatients and outpatients with a history of stimulant abuse (71 males and 29 females) were recruited with informed consent, and were administered the SRRS. The Visual Analogue Scale for drug craving (VAS), Addiction Severity Index for Japanese (ASI-J), and data on relapse within 3 and 6 months after the rating were used for the validation. RESULTS: Exploratory factor analysis highlighted five factors: anxiety and intention to use drug (AI), emotionality problems (EP), compulsivity for drug use (CD), positive expectancies and lack of control over drug (PL), and lack of negative expectancy for drug use (NE). These accounted for 48.3% of the total variance. Thirty of the 43 items were classified into the five subscales. Cronbach's alpha coefficient for each subscale ranged from .55 to .82, and was .86 for the total SRRS, indicating their adequate internal consistency. AI, CD, PL, and total SRRS were significantly correlated with the drug-use composite score of the ASI-J, supporting their concurrent validity. AI, PL, NE, and total SRRS were significantly correlated with relapse, implying their predictive validity. CONCLUSIONS: The SRRS has multidimensional psychometric properties useful for assessing the various aspects of stimulant relapse risk.

The Addiction Severity Index (ASI) is a frequently used clinical and research instrument that collects data from substance abusers in seven problem areas: medical, employment, alcohol, drug use, legal, family-social functioning, and psychiatric status. In each area, the ASI provides a composite score and severity rating that estimate the seriousness of the problem and the client's need for treatment. In the present study, we investigated the reliability and validity of the Japanese version of the ASI (ASI-J). One hundred and eleven subjects with a history of drug abuse were interviewed with a test battery including the ASI with informed consent. This revealed that: (a) the problem areas were independent of each other, underscoring the need for multidimensional assessment, (b) the inter-rater correlation of severity ratings in each area ranged from 0.68 to 0.99, and Cronbach's alpha coefficient for the items used for the composite score in each area ranged from 0.57 to 0.86, indicating their reliability with the exception of the drug and employment areas, and (c) several composite scores were significantly correlated with the drug craving levels assessed by a visual analogue scale, the abstinence period, mental health, and/or relapse, supporting their concurrent and predictive validity. These results suggest that the ASI-J has acceptable reliability and validity.
