The authors examined the effects that differently framed and targeted health messages have on persuading low-income women to obtain screening mammograms. The authors recruited 752 women over 40 years of age from community health clinics and public housing developments and assigned the women randomly to view videos that were either gain or loss framed and either targeted specifically to their ethnic groups or multicultural. Loss-framed, multicultural messages were most persuasive. The advantage of loss-framed, multicultural messages was especially apparent for Anglo women and Latinas but not for African American women. These effects were stronger after 6 months than after 12 months.

The present research moved beyond focusing on negative dispositions to investigate the influence of positive aspects of personality, namely extraversion and openness, on stress responses including appraisals, affect and task performance. Challenge appraisals occur when stressor demands are deemed commensurate with coping resources, whereas threat appraisals occur when demands are believed to outweigh coping resources. We examined the unique influence of personality on stress responses and the mediating role of appraisals. Personality was assessed, and then participants (N = 152) were exposed to a validated math stressor. We found unique effects on stress responses for neuroticism (high threat and negative affect and low positive affect), extraversion (high positive and low negative affect) and openness (high positive and low negative effect and better performance). Mediation analyses revealed that neuroticism indirectly worsened performance, through threat appraisals, and that openness indirectly increased positive affect through lower threat. These findings highlight the importance of investigating multiple aspects of personality on stress responses and provide an avenue through which stress responses can be changed-appraisals. Only by more broad investigations can interventions be tailored appropriately for different individuals to foster stress resilience.

The effects of prior task exposure on cardiovascular reactivity to stress were examined in two experiments by randomly assigning participants to repeated exposure groups that performed mental arithmetic pretest and test tasks versus delayed exposure groups that performed only the test task after prolonged rest. Impedance cardiographic and blood pressure measures were recorded continuously from 60 undergraduate men in Experiment 1 and 112 undergraduate men and women in Experiment 2. Task repetition attenuated cardiovascular reactivity and improved task performance in repeated exposure groups (p < .001), suggesting an integrated process of behavioral adaptation. During the test task, delayed exposure groups showed greater cardiac reactivity (p < .01), but not vascular reactivity, than repeated exposure groups. Thus, cardiac reactivity varied as a specific function of prior task exposure, whereas vascular reactivity varied as a general function of time.

In a randomized experiment, women (N = 441) watched either a loss- or gain-framed video emphasizing the prevention or detection functions of the Pap test to test the hypothesis that loss- and gain-framed messages differentially influence health behaviors depending on the risk involved in performing the behavior. As predicted, loss-framed messages emphasizing the costs of not detecting cervical cancer early (a risky behavior) and gain-framed messages emphasizing the benefits of preventing cervical cancer (a less risky behavior) were most persuasive in motivating women to obtain a Pap test.

Persuasive health messages can be framed to emphasize the benefits of adopting a health behavior (gains) or the risks of not adopting it (losses). This study examined the effects of message framing on beliefs, attitudes, and behaviors relevant to cigarette smoking. In video presentations about tobacco smoking, visual images and auditory voiceover content were framed either as gains or losses, yielding 4 message conditions. Undergraduates ( N = 437) attending a public university in New England were assigned randomly to view one of these messages. Gain-framed messages about smoking in visual and auditory modalities shifted smoking-related beliefs, attitudes, and behaviors in the direction of avoidance and cessation. Health-communication experts, when promoting prevention behaviors like smoking avoidance or cessation, may wish to diverge from the tradition of using lossframed messages and fear appeals in this domain, and instead consider using gain-framed appeals that present the advantages of not smoking.Persuasive messages encouraging smoking cessation are usually designed to elicit feelings of threat or fear by presenting the negative consequences of cigarette smoking. For example, the Surgeon General's warnings on cigarette packs emphasize the health dangers associated with smoking (e.g., emphysema, heart disease, death).
