Examining the Mediating Role of Challenge and Threat Appraisal Tendencies on the Relationships Between Mastery Imagery Ability, Perceived Stress and Proactive Coping

Given the associations between mastery imagery ability, challenge and threat appraisal tendencies, perceived stress and proactive coping, and the implications for health, this research utilised a two-study approach to assess these associations and was the first study to examine whether appraisal states had a mediating role on the relationships of mastery imagery ability with perceived stress and proactive coping. Study 1 used a sample of 148 participants (M age = 22.52, SD = 4.36 years) and Study 2 used a sample of 338 participants (M age = 19.26, SD = 1.58 years). Participants completed online questionnaires measuring mastery imagery ability, challenge and threat appraisal tendencies, perceived stress, and proactive coping. In Study 1, only threat appraisal mediated the relationship between mastery imagery ability and perceived stress. However, both challenge and threat appraisal mediated the relationship between mastery imagery ability and proactive coping. Study 2 results showed challenge appraisal also mediated these relationships, but threat appraisal played no mediating role. Both studies demonstrate the important mediatory role of stress appraisal states, and the role they can have in regulating stress, but further research is warranted to establish when one stress appraisal may mediate the relationship over the other.
