The Effects Of Learning Environment Resources And Psycap On Student Burnout And Outcomes, Elisandra Rodriguez Moreno

Dissertations

This study examined links between learning environmental resources (i.e., social support and feedback environment), burnout, and student outcomes (i.e., satisfaction and academic performance) among 198 graduate healthcare students. The study also investigated whether Psychological Capital (PsyCap) moderated these relationships. Social support and feedback did not predict overall burnout, but both were significantly linked to the burnout dimensions, specifically: emotional exhaustion, depersonalization, and academic efficacy. PsyCap did not moderate most relationships, yet it was consistently associated with lower levels of burnout and higher satisfaction. One exception emerged—for social support and depersonalization, PsyCap served as a compensatory resource, where students with lower …

An Exploration Of Sleep Experiences Among Family Caregivers Of Older Adults With Alzheimer’S And Related Diseases, Caroline Bollettiero
