Product manuals play an important role in the delivery of marketplace safety information. The present study extends prior conceptualizations of individuals' responses to threat communication by explicitly incorporating coping response efficacy and assessing relationships among arousal dimensions and coping appraisal processes in a more naturalistic context (i. e., in-home, self-paced exposure) than previous research. Proposed relationships among arousal, efficacy, and behavioral intentions are tested and largely supported. Based on the findings of the study, issues relevant to researchers and practitioners in the area are discussed.
