  • Profiles in workplace giving: a cluster analysis of ‘types’ of givers within a public university

    by Jorge Ruiz-Menjivar, Tracy Johns, Tara Counts, Yong Liu, Jennifer Amanda Jones

    This study examines public employees’ donations to a workplace giving campaign at a large public university in the south-east of the United States. First, we employed logistic regression to predict the likelihood of donating through workplace giving programmes using a sample of employees at a large public university (N = 11,726). Second, we estimated an ordinary least squares regression to identify the significant predictors of donation value with a subsample of employee donors (n=1,832). Third, we developed donor profiles (for example, clusters) of employee benefactors using K-medoids clustering. Factors such as sex, age, education and salary were significant predictors of both being a donor and the donation amount. Additionally, employment duration was significantly related to being a donor and the donation amount, while job classification only predicted being a donor. Employee donors fell into five distinct clusters. These findings contribute to our knowledge of workplace giving campaigns and can be used to develop strategic marketing campaigns.

    Intrasexual Competition and Unhealthy Weight Control Behaviors among Late Adolescent Females

    by Nicole A. Boyer, Larry F. Forthun, Tracy L. Johns

    The purpose of this study was to test a mediating model whereby competitiveness among females for mates affects body dissatisfaction and dysfunctional diet and exercise through its influence on social comparison and fear of being negatively evaluated by others. The hypothesized model draws from several empirical models, including the sexual competition hypothesis and the tripartite influence model. Approximately 218 female college students completed an online survey. Most participants were heterosexual, White, and between the ages of 19 and 20. The proposed model was tested with MPlus 8.0 using maximum likelihood estimation (MLE). The hypothesized model was a good fit to the data, revealing both direct and indirect paths that were positive and statistically significant. The results suggest that body dissatisfaction may be intensified in environments such as schools wherein peer competition for mates is high and where adolescent females may feel that they cannot successfully compete. They may experience feelings of inadequacy about their bodies, which may result in the adoption of dysfunctional diets, exercise, or other practices that may be unhealthy and potentially life threatening in an effort to change their physical appearance.


  • Managing a Policy Experiment

    by Tracy L. Johns

    The unique nature of recreational marijuana policy makes for a compelling study in the policy adoption and implementation process. As a local control state, Colorado cities, municipalities, and counties may choose whether or not to adopt marijuana legalization policies in their jurisdictions and how to do so. This research is based on survey and panel data from Colorado local officials regarding issues of adoption and implementation in their jurisdictions. Overall, the initial findings show that the decision regarding adoption was a result of a combination of policy determinants (both cultural and economic) and policy diffusion (from prior policies on medical marijuana). Factors related to public opinion, economics, and prior policy on medical marijuana affected both the decision to permit and the decision to prohibit. Policy diffusion also appears important in early implementation, as cities use the existing medical marijuana policies to shape recreational marijuana policies.


  • Adolescent sexual activity and cancer risk: physicians’ duty to inform?

    by Gwendolyn P. Quinn, Susan T. Vadaparampil, Tracy Johns, Kenneth A. Alexander, Anna R. Giuliano

    Yearly, 33,000 cancer diagnoses in the US are attributed to human papillomavirus (HPV), with cervical cancer the most common. HPV is transmitted through sexual contact; HPV types 16 and 18 cause the majority of ano-genital cancers in men and women. HPV causes ∼100% of cervical cancers, ∼90% of anal cancers, and ∼50% of vaginal, vulvar, and penile cancers. HPV is also involved in ∼70% of oropharyngeal cancers (OPCs) in the US. The CDC recommends routine administration to all female (bivalent or quadrivalent vaccine) and male (quadrivalent vaccine) patients at 11-12 years of age; the series may be started as early as 9 years of age. Recent evidence suggests physicians do not universally recommend the vaccine to all adolescents. Additionally, parents may refuse the vaccine due to safety concerns as well as religious and moral beliefs related to onset of sexual debut. It has been suggested physicians should consider discussing HPV vaccine as a cancer prevention tool only, with less focus on the fact that transmission is caused by sexual activity. In this commentary we suggest physicians have a duty to warn parents and adolescents that OPCs may be transmitted through oral sex, which is often perceived as not constituting sexual activity.

    Smoking Cessation in Family Medicine: Effects of an Area Health Education Center Training Program

    by Tracy L. Johns, Elizabeth Lawrence, Leila E. Martini, Grace E. Dunn, Zachary J. Thompson, Kira Zwygart

    Background and Objectives: Many clinicians have not received adequate training in smoking cessation. We examined the effects of a tobacco training program on clinician behavior, attitudes, knowledge, and comfort related to smoking cessation. Methods: In a prospective cohort study, family medicine residents and faculty completed a pretest, followed by an educational intervention that encompassed presentations on smoking cessation resources, motivational interviewing, and the neurobiology of addiction and pharmacotherapy. After 3 months, participants completed a postintervention survey. Results were analyzed using chi-square tests to examine the effects of training. Results: Thirty-three residents and faculty completed the pretraining survey and 25 completed the posttraining survey. Following training, participants were more familiar and comfortable with Public Health Service Clinical Practice Guidelines ( P < .0001). No significant differences were found in performance of the 5 As (Ask, Advise, Assess, Assist, and Arrange) or other behaviors, including providing assistance with counseling, cessation plans, resources, or pharmacotherapy. There were no improvements in knowledge of specific intervention plans or attitudes related to identifying and counseling smokers. Conclusion: A multidisciplinary tobacco training program increases clinician familiarity and comfort with practice guidelines, and may contribute to improving care activities that promote a healthy lifestyle. Future research should explore other interventions that have the potential of changing practice patterns on a larger scale. Future studies should also assess the effect of training programs on patient-oriented outcomes.
