A Preliminary Investigation into the Use of an Imagery Assisted Virtual Reality Intervention in Sport

引用

Journal of Sports Science 2018年第1期6卷 20-30页

作者： lindsay ross-stewart Jeffrey Price Daniel Jackson Christopher Hawkins Department of Applied Health Southern lllinois University Edwardsville Edwardsville IL 62026 USA Department of Information Technology Services Southern Illinois University Edwardsville Edwardsville IL 62026 USA Intercollegiate Athletics McKendree University Lebanon IL 62254 USA Anderson Hospital Maryville IL 62062 USA

This article explains an imagery assisted virtual reality psychological skills training program used with a NCAA Division I baseball team. This is the first time that imagery has been incorporated into a virtual reality program with the goal of increasing mental skills and strategies. Participants for this study were 27 NCAA baseball players. Each participant completed the Sport Imagery Ability Questionnaire and the Test of Performance Strategies Questionnaire at baseline and again after the winter season (2 months later). Results indicated an increase in skill, goals and mastery imagery ability as well as increases in the use of several skills and strategies in both practice and competition. This manuscript focuses on both the development of an Imagery Assisted Virtual Reality program as well as the outcomes of the program.

Investigating the Prevalence and Risk Factors of Depression Symptoms among NCAA Division I Collegiate Athletes

引用

Journal of Sports Science 2017年第1期5卷 14-28页

作者： Charles E. Cox lindsay ross-stewart Brad D. Foltz Department of Education Florida State University Tallahassee FL 32306 USA Department of Applied Health Southern lllinois University Edwardsville Edwardsville IL 62026 USA Athletic Department University of Oklahoma Norman OK 73019 USA

This study aimed to determine an overall prevalence rate for depression symptoms among National Collegiate Athletic Association (NCAA) Division I collegiate athletes while also assessing various risk factors that may increase an athlete"s vulnerability to depression. Using a sample of 950 NCAA Division I athletes, it was found that 33.2% of athletes experienced symptoms of depression, contradicting findings from previous studies that have suggested a prevalence rate lower than the general college population. Female athletes (P = 0.00), underclassmen (P = 0.01), recently injured athletes (P = 0.05), and in-season athletes (P = 0.05), were all found to experience higher rates of depression symptoms than other athletes. It was found that 25.7% of athletes did not know how or where to access mental health treatment at their university, and 44.5% had received no mental health education from their athletic department. The results from this study suggest that depression is a more significant issue in college athletics than previously thought, and they highlight the need for continued improvements to be made in both the understanding of mental health issues in college athletics and the services that are provided to athletes.

“If Somebody Needed Help, I Went Over”: Social Capital and Therapeutic Communities of Older Adult Farmers in British Columbia Floods

引用

International Journal of Disaster Risk Science 2024年第2期15卷 290-301页

作者： Kyle Breen Siyu Ru Luna Vandeweghe Jenna Chiu lindsay Heyland Haorui Wu School of Social Work Dalhousie UniversityHalifaxNS B3H 1S2Canada

Older adults in disaster contexts are often thought of as a passive, vulnerable population that lacks agency and capacities to cope in the aftermath. However, it can be argued that older adults may have underrecognized strengths that can be utilized pre-, peri-, and post-disaster. One of these strengths is older adults' unique social capital that stems from long-standing connections with other members of their respective communities. Using data from in-depth, semistructured interviews with farmers in British Columbia 3–11 months after the 2021 floods, this research explored the experiences of older adult farmers' recovery. The farmers discussed how they leveraged their social capital to aid in their recovery efforts from the flood event. By using their bonding social capital, older adult farmers transformed their existing, deep-rooted connections into post-disaster assistance. This, in turn, generated the idea of the therapeutic community, helping community members cope in the aftermath. This research indicated the need to further examine how older adults in disaster settings can be viewed as assets with community knowledge and skills as opposed to solely as a vulnerable population.
