Problems with self-control are seen as a key cause of problem gambling behavior. Yet, self-control is rarely studied directly in gambling studies. We demonstrated that self-report and behavioral measures (derived from the strength model of self-control) show lower trait self-control in problem gamblers. In Study 1, a sample of 2,208 undergraduate students from the University of Guelph, Canada (73% female, mean age = 19 years, SD = 4) completed a self-report measure of self-control strength. In Study 2, a sample of 296 University of Guelph students and staff (58% female, mean age = 19 years, SD = 2) completed multiple behavioral measures of self-control strength. Both studies demonstrated that, compared to lower-risk gamblers, higher-risk gamblers have relative trait self-control deficits.

Knowledge translation (KT) interventions can facilitate the successful implementation of best practices by engaging and actively involving various stakeholders in the change process. However, for novices, the design of KT interventions can be overwhelming. In this article, we describe our experience as participants in a problem-based case study on planning a KT intervention and reflect on the use of problem-based learning (PBL) to develop knowledge and skills relevant to the KT process. Participants were six fellows and two faculty members attending the 2009 Canadian Institutes of Health Research KT Summer Institute. Participants received a case study asking them to develop a KT intervention with the goal of implementing a stroke response protocol for hospital inpatients. The group was given 5 hours spread over 2 days to complete the learning task. As the members of the small group reflected on their experience with the case study, 4 themes emerged: (1) balancing engaging stakeholders with moving forward; (2) exploring the research gaps and role of the Knowledge-to-Action Framework; (3) investigating methodological approaches for KT research; and (4) experiencing a supportive training environment. Participation in the problem-based case study allowed participants to expand their individual understanding of KT, while fostering the learning experiences of other group members. In a supportive learning environment, participants were able to identify influential stakeholders for the stroke response protocol implementation, discuss potential barriers by stakeholder group, and consider effective KT interventions. Future training initiatives focusing on strengthening KT capacity and knowledge should consider using small-group problem-based case study to facilitate learning.

In two studies it is demonstrated that, in the short-term, slot machine gambling increases self-control strength in problem gamblers. In Study 1 (N = 180), participants were randomly assigned to either play slot machines or engage in a control task (word anagrams) for 15 min. Subsequent self-control strength was measured via persistence on an impossible tracing task. Replicating Bergen et al. (J Gambl Stud, doi:10.1007/s10899-011-9274-9, 2011), control condition participants categorized as problem gamblers persisted for less time than did lower gambling risk participants. However, in the slot machine condition, there were no significant differences in persistence amongst participants as a function of their gambling classification. Moreover, problem gambling participants in the slot machine condition persisted at the impossible tracing task longer than did problem gambling participants in the control condition. Study 2 (N = 209) systematically replicated Study 1. All participants initially completed two tasks known to deplete self-control strength and a different control condition (math problems) was used. Study 2 results were highly similar to those of Study 1. The results of the studies have implications for the helping professions. Specifically, helping professionals should be aware that problem gamblers might seek out gambling as a means of increasing self-control strength.
