O presente trabalho teve como objetivos traduzir e adaptar para o português brasileiro o instrumento psicométrico Drinking Motives Questionnaire-Revised (DMQ-R), apresentando evidências de validade para essa versão. Essa medida avalia quatro dimensões da motivação para o uso de bebidas alcoólicas: motivos de tipo social, realce, coping e conformidade. O trabalho é apresentado em forma de dois artigos independentes. No primeiro, é feita uma revisão seletiva de literatura, buscando apresentar o construto, distingui-lo de expectativas sobre o uso de álcool e enfatizar seu papel como preditores e mediadores em estudos na área. No segundo artigo, são apresentados dois estudos sobre a estrutura fatorial da versão em português brasileiro do DMQ-R. Estratégias exploratórias e confirmatórias foram empregadas de forma complementar para investigar a estrutura mais representativa dos dados amostrais. Um modelo revisado de quatro fatores foi selecionado como a melhor alternativa, sendo apresentadas dificuldades metodológicas dos estudos e sugestões para estudos futuros. / This work aimed to translate and adapt to Brazilian Portuguese the Drinking Motives Questionnaire-Revised (DMQ-R) presenting validity evidences to this version. The measure assesses four dimensions of alcohol use motivation: social, enhancement, coping and conformity. The work is organized in two independent papers. In the first one, a review of the literature is done, presenting the construct, differentiating it from drinking expectancies and emphasizing its role as predictors and mediators of alcohol use. In the second one, two studies regarding the factorial structure of the Brazilian Portuguese version of DMQ-R are presented. Exploratory and confirmatory strategies were employed complementarily to evaluate the most representative structure for the data. A revised, four-factor model was chosen as the best solution. Methodological difficulties and suggestions for future research are discussed.

This study aimed to analyze the prevalence of alcohol and narcotic use among adolescents in the age of 16-19 in private schools in a medium size city in Sweden. The aim was also to identify important risk factors for the use of narcotics. In upper secondary school in Sweden, 74,0 % of the adolescents had consumed alcohol and 18,0 % had used narcotics in the year of 2016. The results in this study showed that the prevalence of alcohol and narcotic use among the adolescents in Sundsvall was similar to the national prevalence, and gender differences were found in the amount of alcohol consumed as well as in types of narcotics used. The most common type of alcohol consumed by females was light beer or cider and wine whereas for males it was strong beer or cider. More males than females had ever used narcotics and the most common type of narcotic was marijuana/hash among both genders. Earlier research and criminological theories have found several risk factors regarding the use of narcotics. The most prominent risk factors found in this study were lack of parental awareness, having deviant peers, lack of school commitment, positive attitudes towards narcotics and alcohol, and lack of leisure time activities. Research shows that the use of narcotics is connected to criminal behavior and identifying relevant risk factors is a must in order to prevent future problems. This study highlighted several important risk factors and suggested where future measures should be aimed. / <p>2017-06-01</p>

Extending prior alcohol expectancy measurement research, this researcher (McMurray, 2013) recently developed the Pharmacological and Social Alcohol Expectancy Scale (PSAES). The PSAES is the only alcohol expectancy measure to date that provides adequate coverage of both social expectancies and the anticipated positive pharmacological effects resulting from alcohol consumption, and was developed and validated in a sample of young adults (aged 18-23). Research has shown that adolescents at high risk for alcohol use disorder (AUD) hold higher expectations of reward from alcohol, suggesting that expectancy patterns may help distinguish at-risk youth. Building upon the previous PSAES validation study, the primary purpose of the current study was to examine whether a version of the PSAES adapted for adolescents (the PSAES-A) provided a valid measure of pharmacological and social alcohol expectancies in adolescents. Results demonstrated that a respecified model of the PSAES-A adequately fit the proposed two-dimensional factor structure and provided justification for the items representing two distinguishable domains: social and pharmacological. The PSAES-A was then used to 1) examine patterns of alcohol expectancies and drinking behaviors in adolescents and 2) investigate whether risk (e.g., sensation seeking personality) was differentially associated with pharmacological and social expectancies in adolescents. Results indicated that pharmacological and social expectancies were differentially associated with various drinking behaviors (e.g., quantity, frequency) and that sensation seeking was significantly associated with both social and pharmacological expectancies in adolescents. The fact that alcohol expectancies differentially predicted quantity and frequency of drinking suggests that different expectancy processes affect adolescent’s decisions about how often they drink versus how much alcohol they consume on a given occasion. Implications and limitations are discussed.

Oral human papillomavirus (HPV) infection and its association with head and neck cancers (HNCs) have been established by many studies. The characteristics of HPV-associated HNCs are distinguishable from those of non HPV-associated HNCs. HPV-associated HNCs are related to sexual behaviour, particularly the lifetime number of oral sex partners. The oral and oropharyngeal HPV epidemiology in South African men has not yet been researched. The objective of this study was to determine the oral and oropharyngeal HPV strain prevalence and associated factors in a selected male population in Pretoria, South Africa. Male factory workers were recruited on a voluntary basis to be part of this study. Oral rinse and gargle samples were tested for 37 HPV types using the HPV linear array genotyping kit (Roche Molecular System). A questionnaire was utilised to obtain information regarding age, medical conditions, substance and alcohol use and sexual behaviour. HIV testing was optional. The HPV prevalence was 5.6% among the men (n=125) aged 17-64 years. High risk HPV (hrHPV) types 16 and 68 were found in two men. Amongst the majority of the participants oral sex seemed to be an uncommon practice however, those participants with hrHPV did practice oral sex. A statistically significant association between HPV infection and an increased number of sexual partners (p=0.027) was seen but not between substance use, HIVstatus or clinical mucosal pathology. Considering the oral and oropharyngeal HPV prevalence found in this study compared to those reported in other countries. It is therefore proposed that a larger nationwide study be conducted to give a more representative view of the burden of oral and oropharyngeal HPV infection in South Africa. / Dissertation (MSc)--University of Pretoria, 2014. / lk2014 / Community Dentistry / MSc / Unrestricted

Introduction: Studies reveal differential cognitive effects of alcohol use, with moderate to heavy alcohol having some beneficial effects in older adults, whereas in young adulthood, heavier alcohol use produces deficits. The aim of the research was to investigate the relationship between patterns of alcohol use and the cognitive and symptomatic functioning of university students over one year, and to discern which demographic, clinical and alcohol factors might moderate cognitive outcomes. Method: The sample included undergraduate Psychology students from a South African University, aged 18 to 23 years (n = 86). The sample was divided into two alcohol use groups based on four categories from the Alcohol Use Disorders Identification Test (AUDIT) (Babor et al., 2001), including a lighter drinking group (Safe/Hazardous, n = 74) and a heavier drinking group (Harmful/Dependent, n = 12). The two drinking groups were statistically equivalent for distribution of age, gender, English first language, race groups, history of neurological or psychiatric vulnerability, a measure of initial intelligence/cognitive reserve (Peabody Picture Vocabulary Test: PPVT-4) (Dunn & Dunn, 2007) and for a measure of test-taking validity (Immediate Postconcussion Assessment and Cognitive Test: ImPACT Impulse Control) (p = < 0.05 in all instances). Participants were tested on the computerized ImPACT battery (ImPACT, 2007) at three intervals over an academic year (May, August, October 2012). Repeated measures ANOVAs were used to investigate cognitive and symptomatic differences between the two alcohol use groups, in association with moderating factors. Results: The heavier drinking group revealed: (i) poorer performance on ImPACT Visual Motor Speed, Reaction Time and Cognitive Efficiency Index scores, including less ability to benefit from practice over time; (ii) symptom reports of severe Numbness/Tingling, Balance problems and Dizziness. Deleterious cognitive outcome was exacerbated by longer lifetime duration of alcohol use, passing out monthly, beer or wine drinking, smoking or substance use. Conclusion: Deleterious cognitive and symptomatic effects of heavy alcohol use are in evidence for undergraduate university students implicating current and/or cumulative alcohol induced brain impairment. The results of the study are of concern for optimal academic performance of students at an early stage of university level study, who engage in heavier (Harmful/Dependent) drinking patterns, with negative implications for future career attainment.

The aim of this study was to explore and describe the intergenerational interactional patterns in a Coloured family where the mother has abused alcohol. Researchers have found that drinking behaviours of parents can have major effects on the children’s lives throughout generations. Substance abuse of a parent has major influences on the family, their interactions, and relationships, mostly between the parent and the child. There is a major gap in the study of the Coloured families and how substance abuse affects their families and children. The study employed Bowen’s constructs of differentiation of self, multigenerational transmission process, triangulation, emotional cut-off, nuclear family emotional system, sibling position, family projection process, and societal regression and utilized analytical generalization of the concepts to achieve its aim. The mother, an older sibling and maternal mother were the main sources of data although the perspective of the mother herself was privileged in the study. Semi-structured interviews were utilized to gather the data. This allowed participants to freely narrate their personal perceptions and experiences of interaction in both the family of origin and the current nuclear family. The research used a single case study of a purposively sampled family. The researcher is a Coloured female who had specific interest in this specific cultural group and their interactional patterns, which optimised cultural familiarity during the research process and reduced the likelihood of potential discriminatory racial bias of the participants. The findings demonstrate that perceptions of interactional patterns in the nuclear family and family of origin coincided with certain of Bowen’s Family Systems concepts, particularly, triangulation and differentiation. However, the need for further exploration of concepts such as the nuclear family emotional system and the family projection process in Coloured families are still needed in future studies. The findings provided insight into the functioning of the relationships and FAMILY INTERACTION IN MATERNAL ALCOHOL ABUSE interactions in both the nuclear family and the family of origin. Limitations of the current study are identified and recommendations for future studies in this field are also offered.

Migrant workers are one of the most rapidly growing populations in the United States (U.S.) and have been significantly affected by HIV/AIDS. More than 9 million people in the U.S., primarily concentrated in Texas, Florida, Washington, California, Oregon, and North Carolina, are migrant farm workers. High prevalence rates are also suspected among migrant worker communities where risky health behaviors appear to be common. Constant mobility, isolation, limited education, substandard housing, and poverty are some of the factors that migrant workers experience and in many cases increases their HIV risk. Recent studies have suggested that ethnic identity or the level of attachment with one’s ethnic group may influence engagement in HIV risk behaviors, a fact that may be important in the development of interventions among ethnic minorities. This study assesses the relationship between ethnic identity and HIV risk behaviors in two different samples; one assesses this relationship at baseline with a total of 431 African American migrant and seasonal workers in Immokalee, Florida. The second analyzes changes in ethnic identity and HIV behaviors in a sample of 270 Hispanic and African American migrant and seasonal workers in Immokalee, Florida. Data from baseline and 6-month follow-up were used in the analyses presented. The results suggest that individuals with higher levels of ethnic identity report lower levels of engagement in some, but not all, of the risky behaviors examined. These findings point to a potentially protective role for ethnic identity among this sample.

In the current study, 226 international students attending Florida International University responded to an Web-based questionnaire that assessed self-reported scores for: acculturation, acculturative stress, alcohol use patterns, perceived peer alcohol use, and perceived injunctive social norms for alcohol use. The purpose of the study was to evaluate structural relations among this set of variables using Structural Equation Modeling (SEM) via AMOS 17.0. The results of SEM analyses documented acceptable fit of a model which hypothesized that relations between acculturation and alcohol use variables are mediated partially by acculturative stress, perceived peer alcohol use, and perceived injunctive social norms. While significant path coefficients were documented for paths between (a) acculturation and acculturative stress and (b) acculturative stress and alcohol use, the coefficients had negative signs, contrary to existing studies investigating these relations among immigrant youth. While paths between (a) perceived peer alcohol use or (b) perceived injunctive social norms and participants’ alcohol use were significant, path coefficients between acculturation and either (a) perceived peer alcohol use or (b) perceived injunctive social norms were not statistically significant. In addition, multiple-group comparisons suggested that social support had a significant moderating influence on several significant paths in the structural model. Specifically, international students reporting higher social support reported lower scores for acculturative stress and alcohol use, in contrast to their counterparts who reported lower scores for social support.

Drug and alcohol abuse in the workplace is a worldwide problem as it impacts on the company efficiency and cost effectiveness. Companies have prioritized the need to find ways of managing and reducing intoxication in the workplace. In South Africa such processes have to occur within the confines of a constitutional right of fair labour practices and other prescriptive labour legislation. An employee has a constitutional obligation to give faithful and diligent service to the employer. Intoxication contradicts this obligation and may pose a security risk in the workplace. It will be incumbent of an employer to prove that the employee was drunk at the relevant time or was affected by liquor or narcotic substance. Suspicion regarding abuse of alcohol and drugs without proper evidence to support such claims will not satisfy the substantive fairness requirements. When it comes to proving that the employee is indeed under the influence of alcohol and drugs in the workplace, many questions arise. Is it necessary for the employer always to conduct a breathalyzer test or even a blood or urine test? Is it sufficient for the employer to lead other evidence like smelled of alcohol, unsteadiness on his feet and slurred speech? The author will attempt to answer these questions. An employee who consumes alcohol or drugs in the workplace can either be disciplined for misconduct or incapacity. The dividing line between misconduct and incapacity is not always clear. The author suggests various ways of dealing with alcohol and drug-related misconduct and incapacity depending on the facts of each case. Disciplinary sanctions should, as far as possible, be designed to discourage repeated alcohol and drug abuse. Different standards of conduct may be expected of different employees given the nature of their work and the degree of their responsibility. Fair discipline requires a fair procedure, fair disciplinary rules and a fair graduated system of punishment. Termination for incapacity occurs if the employee no longer has the capacity work (on account of his alcohol and drug dependence). Termination for misconduct occurs if the employee consistently acts as though he is not bound by the rules of conduct within the employer‟s establishment on account of his repeated alcohol or drug abuse. Discipline should be progressive in nature, intended to remedy rather than merely punish wrongful behaviour. Case law suggests that employers treat alcohol and drug dependence, the same as other illnesses, with sympathy, understanding and compassion. The author suggests that alcohol and drug abuse in the workplace must be dealt with on a case to case basis
