In the developed world, the principal sources of morbidity and mortality are diseases of lifestyle, and one of the central goals of health promotion is the encouragement of risk-reducing behaviour. In a series of 3 studies, the present program of research examined the effect of self-affirmation and manipulated perceived efficacy on perceptions of efficacy, risk perception, and risk-reducing behavioural intentions. Participants were undergraduate students who were randomly assigned to a self-affirmation manipulation (self-affirmation versus no self-affirmation) and a perceived efficacy manipulation (high versus low versus baseline), followed by exposure to negative health risk information (risk of a heart attack or colorectal cancer). Across the 3 studies, factor analyses indicated 3 distinct categories of risk-reducing intentions: intentions associated with maintaining an active lifestyle, seeking medical advice and assessment, and maintaining a healthy diet. There was little evidence that self-affirmation affected efficacy, risk, or intentions. Structural equation modeling and meta-analytic analyses suggested the presence of a suppression effect for risk perception: a manipulation designed to increase perceived efficacy had direct positive effects on risk, but also had indirect negative effects on risk, with measured efficacy acting as a mediator. These analyses also showed that the 3 categories of behavioural intentions had distinct (and often different) antecedents. These results highlight the complexity of variables in health risk behaviour. Implications and future directions are discussed. / Thesis (Ph.D, Psychology) -- Queen's University, 2010-08-20 09:56:44.707

Research has shown that desirable responding can be detrimental to social relationships, achievement and health. This study used an experimental design to (a) induce an increase in desirable responding through threat to self-image and then (b) compare the effectiveness of self-compassionate and self-affirming writing in attenuating that increase. Control groups included no threat exposure, threat exposure alone and threat exposure plus neutral writing. Desirable responding was measured along two dimensions: self-enhancement and exaggerated virtue. Results show the threat did not result in the predicted increase in desirable responding so the effectiveness of the two strategies with regards to attenuating increases in desirable responding could not be examined and compared. However, results do reveal a difference in the mechanism of these two strategies. Engaging in self-compassionate writing resulted in a significant decrease in exaggerated virtue whereas being self-affirmed resulted in a significant increase, suggesting a possible benefit of a self-compassion strategy.

In this study we explored some of the factors associated with biased processing of attitude-relevant information. We were particularly interested in the possibility that a self-affirmation, by reducing self-evaluative concerns, might increase participants' willingness to impartially evaluate information that conflicts with their current views. We examined students' reactions to arguments about increasing tuition as a function of four factors: attitude importance, argument strength, the congruence of arguments with existing attitudes, and our experimental manipulation of affirmation. We found that affirmation reduced biased evaluation only for participants who rated the issue as important. We also found that affirmation dramatically impacted the perception of argument strength. Stronger counterattitudinal arguments were rejected by non-affirmed participants, who did not distinguish them from weak arguments, presumably because of the esteem threat posed by a strong ideological challenge. Affirmed participants, though, evaluated strong counterattitudinal arguments more positively.

A limited number of studies have examined mechanisms undergirding interventions that mitigate mental health problems or health-risk behaviors that disproportionately burden sexual minorities. A recent trial of expressive writing and self-affirmation writing found that these brief interventions had salubrious effects on mental health and health-risk behaviors; the present research examines the putative mechanisms underlying these effects. Sexual minority emerging adults (N = 108) completed a brief online expressive writing, self-affirmation writing, or neutral control writing intervention and, at baseline and 3-month follow-up, completed measures of mental health, health-risk behaviors, stress, and self-regulation. Expressive writing yielded improvements in mental health and these effects were mediated by reductions in perceived stress. Self-affirmation caused improvements in health-risk behaviors, thoughneither stress nor self-regulation mediated these effects. This finding provides preliminary novel evidence regarding a mechanism underlying a widely used psychological intervention with documented mental health benefits for sexual minorities and other populations disproportionately affected by stress

This research proposes a new construct, post-purchase anticipated regret (PPAR), to expand the existing retailing and regret theory literature streams. Specifically, the purpose of this research is to understand the antecedents and consequences of post-purchase anticipated regret in an online retailing context. Study 1 uses qualitative data drawn from depth-interviews with online shoppers to investigate the pre-purchase factors that contribute to PPAR formation. Building from these results, studies 2 and 3 empirically test an original conceptual model to holistically understand PPAR. Additionally, the role of online shopping self-affirmation and regret coping strategies are explored as means to combat PPAR formation. Managerial and theoretical implications are offered, as well as research limitations and future research directions.
