Brief Motivational Intervention and telemedicine: a new perspective of treatment to marijuana users.

The main purpose of this study was to evaluate the telephone Brief Motivational Intervention (BMI) efficacy in marijuana consumption cessation. A clinical trial was performed on Brazilian citizens, who were randomly divided into experimental (BMI) and minimal intervention (reference material) treatment groups; the study involved 524 participants who were monitored for 6 months. In addition, the data was collected by a free-service call center; both marijuana consumption and level of motivation for behavior change were evaluated, based on the telephone service offered. The proportion of abstainers in the BMI group was significantly greater than in the control group: 73% of the individuals in the BMI group were abstainers. In the control group, 59% of them ceased on using marijuana. The ratio of probability for marijuana cessation was 1.6 times higher in the BMI group. There was no significant difference on the motivation for behavior change in both groups. The collected data demonstrated the telephone BMIs positive efficacy in marijuana consumption cessation.

A violência comunitária e o abuso de álcool entre adolescentes: comparação entre sexos

OBJECTIVE To verify whether there is an association between victimization and alcohol use among boys and girls in Porto Alegre, RS, Brazil. METHODS This was a cross-sectional study of students from public schools, aged 10 to 19 years, from the fifth grade of primary education to the third grade of secondary education, selected by two-stage cluster sampling, defined by the socioeconomic characteristics of the neighborhood in which each school is located and by school class. Data collection was by means of a questionnaire which was completed anonymously and voluntarily. RESULTS Fifty-four percent of the older adolescent boys (aged 14-19) drank alcohol, compared to 17% of the younger adolescent boys (10-13), as did 58% of the older adolescent girls and 19% of the younger adolescent girls. Fifty-seven percent of the students had suffered severe victimization, and 53% had suffered moderate victimization. When the samples were separated by sex, it was observed that boys and girls who drank alcohol reported 2.6 and 1.8 times more severe victimization respectively, while alcohol was associated with 3.1 and 2.5 times greater prevalence of moderate victimization, among boys and girls respectively. When episodes of drunkenness were analyzed, it was observed that adolescents got drunk more than pre-adolescents and that exposure to violence exhibited an increased association with drunkenness. Thirty-two percent of the boys (prevalence ratio, PR = 4.4; 95%CI 2.6-7.3) and 22% of the girls (PR = 2.2; 95%CI 1.2-4.1) who had been the victims of severe violence reported being drunk at least once. CONCLUSIONS Adolescents of both sexes who consume more alcohol are at greater risk of suffering community violence.

Quality of life of users of psychoactive substances, relatives, and non-users assessed using the WHOQOL-BREF

Quality of life is related to one of the basic human desires, which is to live well and feel good. The scope of this study was to evaluate the quality of life of psychoactive substance users and relatives, compared to non-users, analyzed by socioeconomic strata. A cross-sectional study with users of psychoactive substances, relatives, and other individuals who called the Information and Orientation Service regarding drug abuse. Data collection took place between November 2009 and December 2010. Data was collected from users, relatives, and non-users, including socioeconomic characteristics and data regarding substance consumption when appropriate. In addition to this the abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire was given to 347 individuals. Among the 138 users (70%) used alcohol, 76 (39%), marijuana, 111 (57%) tobacco, 78 (40%) cocaine and 70 (36%) crack. Control subjects had higher, scores than the relatives of users and users in all areas of the questionnaire (p < 0.05). Psychoactive substance users scored lower in almost all domains and overall score in the WHOQOL-BREF questionnaire in comparison with the sample of non-drug users. These findings reflect poor quality of life of patients and their relatives.

Non-authoritative parents and impact on drug use: the perception of adolescent children.

OBJECTIVE To evaluate the association between drug use and parenting styles perceived by Brazilian adolescent children. METHODS This cross-sectional study enrolled adolescents aged 14 to 19 years that used the Serviço Nacional de Orientações e Informações sobre a Prevenção do Uso Indevido de Drogas (VIVAVOZ). A total of 232 adolescents participated in the study. Phone interviews were conducted using the Parental Responsiveness and Demandingness Scale, which classifies maternal and paternal styles perceived by adolescent children as authoritative, neglectful, indulgent or authoritarian. Sociodemographic variables were collected and an instrument was used to assess monthly drug use and abuse. RESULTS Maternal and paternal parenting styles perceived as neglectful, indulgent or authoritarian (non-authoritative) were significantly associated with drug use (odds ratio [OR] = 2.8; 95% confidence interval [95%CI], 1.3-5.7 for mothers and OR = 2.8; 95%CI, 1.3-6.3 for fathers). Non-authoritative styles also had a significant association with tobacco use in the previous month in the analysis of maternal (OR = 2.7; 95%CI, 1.2-6.5) and paternal (OR = 3.9; 95%CI, 1.4-10.7) styles, and use of cocaine/crack in the previous month (OR = 3.9; 95%CI, 1.1-13.8) and abuse of any drug (OR = 2.2; 95%CI, 1.0-5.1) only for the paternal style. Logistic regression revealed that maternal style (OR = 3.3; 95%CI, 1.1-9.8), adolescent sex (OR = 3.2; 95%CI, 1.5-7.2) and age (OR = 2.8; 95%CI, 1.2-6.2) were associated with drug use. CONCLUSIONS Adolescents that perceived their mothers as non-authoritative had greater chances of using drugs. There was a strong association between non-authoritative paternal styles and adolescent drug abuse.

Efficacy of the telephone-based Brief Motivational Intervention for alcohol problems in Brazil

BACKGROUND The Brief Motivational Intervention (BMI) is an effective treatment for alcohol misuse but has not been adequately tested for use in helplines for alcoholics. The main objective of this study was to evaluate the efficacy of a telephone-based BMI for Brazilians seeking help with alcohol use cessation. METHODS A randomized, controlled trial was performed with Brazilian subjects. Participants were randomly assigned to either the minimal intervention group (i.e., given reference materials) or the BMI group. Alcohol abstinence was evaluated in a 6-month follow-up telephone counseling session. The analysis was based on the intention to treat (ITT). RESULTS Of the 5,896 drug users who called the helpline, 700 (12%) used alcohol, 637 of whom enrolled in this study. At 6-month follow-up, 70% of the BMI group had stopped consuming alcohol compared to 41% in the control group (odds ratio = 1.5; 95% confidence interval = 1.2-1.9; p = 0.001). CONCLUSIONS A helpline-based BMI helps alcohol users achieve abstinence.

A eficácia das intervenções farmacológicas e psicossociais para o tratamento do tabagismo: revisão da literatura

Efficacy of pharmacological and no-pharmacological treatments for smoking cessation. Smoking cessation is associated to health benefits, because individuals who stop smoking will avoid most tobacco-related disorders. Our aim was to review the most important characteristics and the efficacy of the pharmacological and psychossocial treatments available for tobacco smokers, presenting meta-analysis and randomized clinical trials fundamental conclusions. Pharmacological interventions involving nicotine replacement and antidepressant use, with bupropion as the first line agent, and psychossocial interventions involving cognitive behavioral therapies and face-to-face or phone-based motivational interventions are proving to be efficacious. Pharmacotherapies increase two-fold the chance of abstinence and face-to-face or phonebased psychosocial interventions increase the chance of quitting smoking in 1.5 to 2.5 times in comparison to individuals who try to quit smoking by themselves. These data support health professionals to decide the most effective treatment for individual smokers, according to the available interventions tested, their efficacy and the benefits of use.

Convergent validation study of the Contemplation Ladder for application via telephone in tobacco users

objective: This work was designed to validate the Portuguese version of the Contemplation Ladder, whose purpose is to assess the motivational phase to quit smoking among tobacco users using a telephone service. method: A cross-sectional study was conducted in a nationwide drug use information hotline. In order to assess the convergent validation, the correlation between the Contemplation Ladder and the URICA Scale was calculated, which was previously validated. results: The study included 271 tobacco users. Statistically significant correlations were found between the Contemplation Ladder scores and the scores of the URICA precontemplation (r=-0.16; p<0.01), action (r=0.15; p<0.01) and maintenance (r=0.18; p<0.01) subscales. The correlation between the URICA Scale compound score and the Contemplation Ladder was also significant (r=0.31; p<0.01). conclusion: The results of our study suggest that the Contemplation Ladder can be an efficient substitute for the URI CA scale (whose application lasts at least 20 minutes), without submitting the interviewee to a heavy load of questions. The study presented evidences of convergent validity for the Contemplation Ladder when applied via telephone in tobacco users.
