Stages of change among ethnically diverse college students

The authors applied the stage-of-change construct in the transtheoretical model to examine the distribution of Asian (n = 869), African American (n = 373), White (n = 1322), and Hispanic (n = 535) American undergraduate students across the 5 stages of change for exercise. Stage of change varied as a function of ethnicity. Higher percentages of minorities were in the precontemplation and contemplation stages. The likelihood of being in these stages was from 43% to 82% greater for minorities than for White students. Also examined were the congruency between stage of change and self-reported levels of physical activity. Half of the sedentary students and 15.6% of the active students were misclassified by the stage-of-change procedure. Misclassification rates were higher for minority women (27.8%) than for White women (17.8%) and for Asian students (24.6%) compared with all others (20.6%). The results of this study have implications for the design of physical activity interventions based on stage of change.     

Harm Reduction and Electronic Gambling Machines: Does this Pair Make a Happy Couple or is Divorce Foreseen?

Recent empirical studies have evaluated if modifying electronic gambling machine (EGM) structural features could encourage safer gambling behaviors and decrease gambling-related problems. Several of these studies refer to Harm Reduction (HR), suggesting that the HR paradigm is useful to design, implement and test the efficacy of various prevention and treatment programs applied to EGM users. After reviewing the origins of HR and specifying its operational definition, this paper discusses the relevance of the HR framework for the study of measures related to EGM use and gambling in general. Examples are given to illustrate the arguments. The results show that HR has been over-inclusive in the field of gambling. A specific and operational definition and application of the HR framework is required for HR to be useful for the advancement of research in the gambling field. Disclosure: At the time of the study, Michael Cantinotti held a scholarship from the Loterie Romande (public-benefit lottery in Switzerland) for his doctoral studies. This study was funded by the Fonds pour la prévention et le traitement du jeu of the Fondation de l’Université Laval. During the study, the Centre québécois d’excellence pour la prévention et le traitement du jeu received financial support from the Ministère de la Santé et des Services Sociaux du Québec, the Fonds Québécois de la Recherche pour la Santé et la Culture, Loto-Québec, the Ontario Problem Gambling Research Center, and Harrah’s Operating Funds.     

The Influence of Gaming Expenditure on Crime Rates in South Australia: A Local Area Empirical Investigation

Although there has been much speculation about the possible links between gambling and crime rates, relevant quantitative evidence has been practically non-existent in Australia to date. This paper reports the results of research that utilised a model designed to investigate the potential relationship between electronic gaming machine expenditures and property (income-generating) crime rates reported to police in local areas in South Australia in 2002–2003. The research found that the higher the expenditures on gaming machines in a particular local area per adult, the higher the income-generating crime rate in that area. No such relationship was found between gaming machine expenditure and non-income-generating crime rates. However, further research is required before any policy-relevant conclusions can be drawn.     

Conversational evidence in therapeutic dialogue

Family therapists' participation in therapeutic dialogue with clients is typically informed by evidence of how such dialogue is developing. In this article, we propose that conversational evidence, the kind that can be empirically analyzed using discourse analyses, be considered a contribution to widening psychotherapy's evidence base. After some preliminaries about what we mean by conversational evidence, we provide a genealogy of evaluative practice in psychotherapy, and examine qualitative evaluation methods for their theoretical compatibilities with social constructionist approaches to family therapy. We then move on to examine the notion of accomplishment in therapeutic dialogue given how such accomplishments can be evaluated using conversation analysis. We conclude by considering a number of research and pedagogical implications we associate with conversational evidence.     

Roles of organizers and champions in building campus-community prevention partnerships

OBJECTIVE: A campus-community partnership can be an effective vehicle for launching environmental strategies to prevent college alcohol-related problems. In this study, the authors' primary aim was identifying key factors that facilitate or impede colleges' efforts to build campus-community partnerships. PARTICIPANTS AND METHODS: From fall 2004 to summer 2006, administrators at five 4-year colleges participated in a multisite case study. Level of partnership development was the primary outcome. RESULTS: Three interrelated factors facilitated higher-developed partnerships: college staff assigned to facilitate the partnerships who worked as community organizers, higher-level college administrators who served as aggressive champions, and community initiation of the partnership. The authors did not observe this trio of factors among the less-developed partnerships. A lack of administrative support made it more difficult for a champion to emerge, a college administrator who staunchly advocated for a campus-community partnership, and for those assigned to facilitate the partnership to carry out their work. CONCLUSIONS: Colleges should appoint higher-level administrators to serve as champions, while also ensuring that those assigned to facilitate a partnership can apply community organizing skills.

Adolescent Gambling: Understanding the Role of Stress and Coping

The central variables of stress, coping, and gambling severity were examined along three lines of inquiry. The first addressed whether adolescents with gambling problems reported a greater number of minor or major stressful (i.e., negative) life events relative to others. The second examined whether more with gambling problems employed less-effective coping styles, such as those characterized as less task- or solution-focused, and more emotion- or avoidance-focused coping. Finally, the third question explored whether adolescents’ coping styles mediated the association between stress and gambling severity. Ranging from 11 to 20 years of age, 2,156 high-school students completed instruments assessing gambling involvement, gambling severity, stressful life events, and coping styles. Results indicated that, overall, adolescents with gambling-related problems reported more negative life events relative to social gamblers and non-gamblers. When negative life events were further separated into major and minor events, results revealed that problem gamblers reported more major negative life events but not more minor negative life events relative to others. Results indicated that adolescents with gambling-related problems used less task-focused coping, and more avoidance-focused coping. Males, but not females, who experience gambling-related problems reported using more emotion-focused coping strategies. Finally, emotion-oriented coping was found to mediate the relationship between negative life events and gambling severity. Implications and directions for future research are discussed.

eHealth recruitment challenges

Little is known about effective eHealth recruitment methods. This paper presents recruitment challenges associated with enrolling African-American girls aged 8–10 years in an eHealth obesity prevention program, their effect on the recruitment plan, and potential implications for eHealth research.Although the initial recruitment strategy was literature-informed, it failed to enroll the desired number of girls within a reasonable time period. Therefore, the recruitment strategy was reformulated to incorporate principles of social marketing and traditional marketing techniques. The resulting plan included both targeted, highly specific strategies (e.g., selected churches), and more broad-based approaches (e.g., media exposure, mass mailings, radio advertisements).The revised plan enabled recruitment goals to be attained. Media appeared to be particularly effective at reaching the intended audience. Future research should identify the most effective recruitment strategies for reaching potential eHealth audiences.     

Worksite e-mail health promotion trial: Early lessons

In preparation for an electronic mail (e-mail) and web-based health promotion intervention across multiple worksites, secure, regulatory-compliant, user-friendly e-mail and Internet applications were used to recruit potential participants across worksites, to enroll participants, and to collect baseline health assessment data. Specific hardware and software information technology environments were required of the 19 participating worksites. Sequential e-mails introduced the study and invited participation. Twenty-four percent of all employees (1106 of approximately 4600) provided consent. E-mail delivered a web link for the baseline study assessment, and reminder e-mails were sent to prompt completion. Of those who consented, 888 (80%) completed baseline health and behavior data surveys. An HTML-native web survey software was more stable across computing environments. Using e-mail and web assessment, this research recruited, enrolled, and collected data from more than 850 participants. Technical and operational challenges emerged at each step. Solutions and recommendations are discussed. Overall, this experience suggests that the use of e-mail and web software can facilitate recruitment, enrollment, and data acquisition through direct contact with study participants. This experience yields a series of lessons learned for using e-mail and the Internet to support multi-site trials.
