Item Success Training for Academic Resiliency: An Advising Intervention Program for Undergraduate Students on Probation(Journal of Interdisciplinary Studies in Education, 2022-12-05) Liu, Charles; Bruner, Justin; Ammigan, RavichandranIn this paper, we examine how Success Training for Academic Resiliency (STAR) Lite, an advising intervention program, influenced undergraduate students to overcome academic probation into achieving good academic standing. We use descriptive quantitative methods to assess the impact of program participation for 194 undergraduate students on academic probation at a large public university in the Midwestern region of the United States. We found that 153 students who participated in the STAR Lite program returned to good academic standing after one semester of intervention, in comparison to 41 undergraduate students who did not participate and did not improve academically. The implication of the findings suggests that students participating in all or extra of the intervention program components overall improved their academic status from probation to good standing.Item Using the Theory of Planned Behavior to determine COVID-19 vaccination intentions and behavior among international and domestic college students in the United States(PLoS ONE, 2024-02-02) Liu, Cheng-Ching; Ling, Jiying; Zahry, Nagwan R.; Liu, Charles; Ammigan, Ravichandran; Kaur, Loveleen; Mehmood, KhalidVaccination is the most effective strategy for preventing infectious diseases such as COVID-19. College students are important targets for COVID-19 vaccines given this population’s lower intentions to be vaccinated; however, limited research has focused on international college students’ vaccination status. This study explored how psychosocial factors from the Theory of Planned Behavior (TPB; attitudes, perceived behavioral control, subjective norms, and behavioral intentions) related to students’ receipt of the full course of COVID-19 vaccines and their plans to receive a booster. Students were recruited via Amazon mTurk and the Office of the Registrar at a U.S. state university. We used binary logistic regression to examine associations between students’ psychosocial factors and full COVID-19 vaccination status. Hierarchical multiple regression was employed to evaluate relationships between these factors and students’ intentions to receive a booster. The majority of students in our sample (81% of international students and 55% of domestic students) received the complete vaccination series. Attitudes were significantly associated with all students’ full vaccination status, while perceived behavioral control was significantly associated with domestic students’ status. Students’ intentions to receive COVID-19 vaccines were significantly correlated with their intentions to receive a booster, with international students scoring higher on booster intentions. Among the combined college student population, attitudes, intentions to receive COVID-19 vaccines, and subjective norms were significantly related to students’ intentions to receive a booster. Findings support the TPB’s potential utility in evidence-based interventions to enhance college students’ COVID-19 vaccination rates. Implications for stakeholders and future research directions are discussed.
