Understanding and Attenuating Overreported TV News Exposure: Testing Anonymity, Self-Affirmation, and Cognitive Survey Manipulations

ABSTRACT Research has demonstrated time and again that peoples’ self-reports of news exposure are heavily inflated and the reasons for this overreporting remain unclear. In three online survey experiments conducted in Israel, we manipulated the survey procedure to test cognitive and motivational explanations, and attempted to attenuate inflated reports of news exposure. While increasing or decreasing the anonymity of the survey (the ultimate test for social desirability) did not affect participants’ responses, a self-affirmation manipulation reduced reported exposure. A memory-aid manipulation also reduced reported television news exposure, suggesting that the cognitive mechanism possibly relates to memory failure.

Comparing self-affirmation manipulations to reduce alcohol consumption in university students

Objective: Self-affirmation theory proposes that defensive processing prevents people from accepting health-risk messages, which may explain university students’ dismissal of risk-information about binge drinking. SA-interventions may encourage non-biased processing of such information through impacting on interpersonal feelings and self-esteem. This study compared two self-affirmation manipulations on interpersonal feelings, self-esteem, message processing, message acceptance and subsequent alcohol consumption. Participants: UK university students (N = 454). Methods: Participants were randomly allocated to one of three conditions (Self-affirmation Implementation Intention, Kindness Questionnaire, Control) before reading health-risk information about binge drinking. This was followed by measures of interpersonal feelings, self-esteem, message processing, acceptance and behavioral intentions. Alcohol consumption was assessed one week later. Results: The self-affirmation manipulations had non-significant effects on all outcome variables. Conclusion: Consistent with previous research, the results indicate that self-affirmation interventions are not effective for reducing alcohol consumption in university students.

Reducing the Impact of Stereotype Threat on Women‘s Math Performance: Are Two Strategies Better Than One?

INTRODUCTION: Two studies examined whether stereotype threat impairs women's math performance and whether concurrent threat reduction strategies can be used to offset this effect. METHOD: In Study 1, collegiate men and women (N = 100) watched a video purporting that males and females performed equally well (gender-fair) or males outperformed females (gender differences) on an imminent math test. In Study 2, (N = 44) women viewed the gender differences video, followed by misattribution (cue present, absent) and self-affirmation (present, absent) manipulations, before taking the aforesaid test. RESULTS: In the initial study, women underperformed men on the test after receiving the gender differences video, whereas no gender differences emerged in the gender-fair condition. In Study 2, affirming the self led to better performance than not doing so. Planned contrasts indicated, however, that only women receiving a misattribution cue and self-affirmation opportunity outperformed their counterparts not given these reduction strategies. DISCUSSION: These findings are discussed relative to Stereotype Threat Theory and educational implications are provided.

Morality or competence? The importance of affirming the appropriate dimension of self-integrity.

Two studies explored the relative efficacy of a morality-based versus a competence-based self-affirmation manipulation at increasing acceptance of personally relevant health risk information. In accordance with prior theorizing (e.g., Cohen & Sherman, 2014), it was hypothesized that the morality affirmation would be more effective than the competence affirmation in such contexts, as the former targets a different domain to that threatened by the health risk information. Both studies employed a cross-sectional experimental design. Participants were presented with a morality affirmation, competence affirmation, or no affirmation control prior to reading a message about the risks of (1) not engaging in daily dental flossing (Study 1) and (2) red meat consumption (Study 2). Participants subsequently completed a number of measures assessing acceptance of the message. In line with predictions, findings from both studies demonstrated that the morality affirmation precipitated greater acceptance of personally relevant health risk information compared to the competence affirmation, as reflected in more positive attitudes (Studies 1 and 2) and intentions (Study 1). Study 2's findings further suggested that the superior efficacy of the morality affirmation in health-related contexts could not simply be attributed to a general tendency for this affirmation to outperform the competence affirmation. The nature of the value affirmed may be a critical factor in determining the success of self-affirmation manipulations in health-related domains. Statement of contribution What is already known on this subject? Self-affirmation has been shown to promote openness to personally relevant health risk information across a variety of behavioural domains. The most frequently utilized self-affirmation manipulation involves participants reflecting on a personally important value; however, participants typically self-select the value they reflect on. This means that the nature of the value that is affirmed may vary from person to person within a given study, seriously limiting the interpretability of the findings. What does this study add? This study manipulated the domain of the value affirmed prior to reading a health risk message. Findings suggest that a morality affirmation is most effective at promoting openness to the message. This study highlights the importance of value domain in determining the success of self-affirmation.

Impact of brief self-affirmation manipulations on university students' reactions to risk information about binge drinking.

Binge drinking is associated with an array of negative health consequences and is particularly prevalent in university students. Health-risk messages about alcohol may fail to change such behaviour because they are dismissed or derogated. The present study sought to compare the effect of three brief self-affirmation manipulations on message processing, message acceptance, and subsequent alcohol-related behaviour in university students. Participants (N=307) were randomly allocated to condition (kindness questionnaire, values essay, attributes questionnaire, control questionnaire) before reading a health-risk message about binge drinking. After reading the message, participants completed measures of message processing (message reactance, message evaluation, counter-arguing) and message acceptance (perceived risk, intention, plans) as well as a manipulation check. Alcohol consumption was assessed 1week later. Participants in all three self-affirmation conditions scored significantly higher than participants in the control condition on the manipulation check measure. All other self-affirmation effects were non-significant. While the three self-affirmation manipulations were found to be self-affirming, they failed to impact on measures of message processing, message acceptance, or subsequent behaviour. The findings concur with previous research that questions the use of self-affirmation to reduce alcohol consumption in university students. Current self-affirmation manipulations may not be strong enough to overcome defensive processing of health-risk messages about alcohol in students and/or prime social goals that are related to the domain under threat (i.e., alcohol consumption), thereby nullifying any positive self-affirmation effects. Statement of contribution What is already known on this subject? Health-risk messages to reduce alcohol consumption (e.g., binge drinking) in university students may fail due to defensive processing (e.g., message derogation). Self-affirmation has been proposed as a technique to bolster one's self-integrity and promote open-minded processing of health-risk messages. Most previous studies that have presented health-risk messages about alcohol to university students have used a values essay to self-affirm participants with equivocal results. What does this study add? There are few studies that have directly compared different self-affirmation manipulations. All three self-affirmation manipulations were found by participants to be self-affirming, consistent with the idea that there are multiple ways individuals can self-affirm, but had no significant effects on message processing, message acceptance, or behaviour. Self-affirmation manipulations may lead individuals to reflect on interpersonal values that are related to alcohol consumption in students and may therefore prime the very cognitions and behaviour that they seek to reduce.

Self-affirmation and responses to health messages: a meta-analysis on intentions and behavior.

The present study aimed to quantify the magnitude of the effect of self-affirmation manipulations on health messages' influence on both intentions and behavior. A systematic search was conducted for experimental studies comparing participants who self-affirmed prior to reading a threatening health message to those who did not self-affirm. Effect sizes for health intentions and behaviors were aggregated using a random-effects model. Data from 16 studies were included. The aggregate effect sizes for intentions and behavior were significant and small in magnitude (d+ = .26, 95% confidence interval [CI] = .04-.48; d+ = .27, 95% CI = .11-.43, respectively). A meta-regression analysis revealed that among studies assessing both outcomes, the size of an effect on intentions did not predict the size of an effect on behavior, β = .03, 95% CI = -.30-.36. Type of health behavior (damaging vs. promoting), timing of the health behavior (proximal vs. distal), type of self-affirmation manipulation (values vs. kindness), and the specificity of the health message (single vs. multiple health issues) did not moderate the effect of self-affirmation on intentions or behavior. Self-affirmation influences health messages' effect on intentions and behavior; however, with the present study finding that intention effect sizes did not predict behavior effect sizes, and with past studies of heath behavior change finding that intentions do not always translate to behavior, little research supports a causal intention-behavior relation among self-affirmation studies. Future research is needed to address which specific health-related responses explain why self-affirmation elicits health behavior change.

The moderating impact of self‐esteem on self‐affirmation effects

This study explored whether self-esteem would moderate the effectiveness of a self-affirmation manipulation at increasing openness to personally relevant health-risk information. The study employed a prospective experimental design. Participants (N = 328) completed either a self-affirmation manipulation or a control task, prior to reading information detailing the health-related consequences of taking insufficient exercise. They then completed a series of measures assessing their cognitions towards exercise and their derogation of the information. Exercise behaviour was assessed at 1-week follow-up. Self-esteem moderated the impact of self-affirmation on the majority of outcomes. For participants with low self-esteem, the self-affirmation manipulation resulted in more positive attitudes and intentions towards exercise, together with lower levels of derogation of the health-risk information. By contrast, there was no effect of the self-affirmation manipulation on outcomes for participants with high self-esteem. Findings suggest that self-affirmation manipulations might be of particular benefit for those with low self-esteem in terms of promoting openness towards health-risk information. This is promising from a health promotion perspective, as individuals with low self-esteem often represent those most in need of intervention. Statement of contribution What is already known on this subject? Self-affirmation has been shown to result in more open processing of personally relevant health-risk information. Individuals low in self-esteem tend to process such information more defensively than those high in self-esteem. What does this study add? It explores whether self-esteem moderates the impact of self-affirmation on responses to health-risk information. Findings suggest that individuals with low self-esteem benefit most from the self-affirmation manipulation. This has important applied implications, as individuals with low self-esteem may be most in need of intervention.

Combining Self-Affirmation and Implementation Intentions: Evidence of Detrimental Effects on Behavioral Outcomes

There is limited evidence that self-affirmation manipulations can promote health behavior change. The purpose of this study was to explore whether the efficacy of a self-affirmation manipulation at promoting exercise could be enhanced by an implementation intention intervention. Participants (Study 1 N = 120, Study 2 N = 116) were allocated to one of four conditions resulting from the two (self-affirmation manipulation: no affirmation, affirmation) by two (implementation intention manipulation: no implementation intention, implementation intention) experimental design. Exercise behavior was assessed 1 week post-intervention. Contrary to prediction, those participants receiving both manipulations were significantly less likely to increase the amount they exercised compared to those receiving only the self-affirmation manipulation. Incorporating an implementation intention manipulation alongside a self-affirmation manipulation had a detrimental effect on exercise behavior; participants receiving both manipulations exercised significantly less in the week following the intervention.

Cognitive self‐affirmation inclination: An individual difference in dealing with self‐threats

The current research shows that people differ in their inclination to use positive self-images when their self is threatened (i.e., cognitive self-affirmation inclination, CSAI). Just as self-affirmation manipulations do, the use of positive self-images induces open mindedness towards threatening messages. The aim of the current studies was to show the meaning, stability, and effects of this new individual difference measure. A cross-sectional study among smokers (Study 1) showed that people with a strong CSAI perceived more negative consequences from smoking, suggesting open mindedness. Study 2 showed the stable and reliable character of the CSAI scale. Study 3 showed that the scale had an overlap of 18% with another self-related construct (self-efficacy) and no relation with self-consciousness. Study 4 showed that for induced self-threats a strong CSAI led to the same pattern of persuasion as found in earlier studies on self-affirmation manipulations. Study 5 showed that a self-affirmation manipulation did not have any effect for those participants with a strong self-affirmation inclination, probably because they already had access to positive self-images. Study 6 showed that self-reported positive self-images mediated the effect of self-affirmation inclination on persuasion.

Testing multiple means of self-affirmation

The effects of self-affirmation manipulations are not yet well understood because several different affirmation manipulations have been tested using multiple dependent variables. The aim of the present research was to establish whether global self-feelings and self-esteem, or interpersonal positive feelings are affected by affirming the self. Experiment 1 showed that completing a kindness questionnaire led to adolescent girls reporting more positive interpersonal feelings, but no greater self-feelings or self-esteem than completing an opinions (control) questionnaire. Experiment 2 showed again that self-affirmation did not affect self-esteem, and that there were few differences between writing an essay about a cherished value, writing an essay about kindness, or completing a questionnaire about kindness in boosting positive interpersonal feelings. The findings are discussed in relation to self-affirmation theory and the possible practical implications of self-affirmation for aiding the delivery of social and health messages.

Pro‐environmental actions, climate change, and defensiveness: Do self‐affirmations make a difference to people's motives and beliefs about making a difference?

Social concerns with the imperative of environmentally sustainable life-styles sit rather awkwardly with ideas about the widespread denial of global environmental problems. Given the very obvious threat and denial dimensions to these issues, we conducted two studies assessing the impact of self-affirmation manipulations on people's beliefs and motives regarding pro-environmental actions. In Study 1, participants (N=125) completed a self-affirmation task and read information on the threat of climate change. Results showed that the self-affirmation manipulation resulted in lower levels of denial and greater perceptions of personal involvement in relation to climate change. In Study 2, participants (N=90) completed a self-affirmation task and read some information on recycling. Findings showed a beneficial effect of a self-affirmation manipulation on intentions to increase recycling behaviour (among lower recyclers). The results are discussed in relation to the potential benefits of self-affirmation manipulations for promoting pro-environmental actions.

Reducing defensive distancing: Self-affirmation and risk regulation in response to relationship threats

The risk regulation model proposes that people with low self-esteem, but not those with high self-esteem, react to relationship-based self-threats by defensively distancing from their partner. In the present study, we hypothesized that a self-affirmation manipulation, by restoring self-worth and integrity for people with low self-esteem, would attenuate this defensive distancing behavior. Participants were exposed to either a relationship-based self-threat or no such threat, and then completed a self-affirmation or a control task. As predicted, when presented with a self-threat, individuals with low self-esteem distanced from their partner. This effect was attenuated if they were given the opportunity to self-affirm. By contrast, the threat and self-affirmation manipulations had no effect for those with high self-esteem. Results are discussed in terms of their implications for risk regulation theory and self-affirmation theory.

Motivational and behavioural consequences of self-affirmation interventions: A study of sunscreen use among women

The reported study compared the efficacy of three self-affirmation manipulations in reducing defensive processing and instigating behaviour change in response to personally relevant information about the health risks of sunbathing. White female sunbathers (N = 162) were recruited on a beach in the south of England. Participants were randomly allocated to a ‘values affirmation’ condition, a ‘kindness affirmation’ condition, a ‘positive traits affirmation’ condition, or a no affirmation ‘control’ condition. In the ‘positive traits affirmation’ condition the self-affirmation task was incorporated into a leaflet presenting the health risk information. Findings supported the hypothesis that participants in the three self-affirmation conditions would engage in less-defensive processing of the health-risk information than those in the ‘control’ condition. For the behavioural measure, however, only those participants in the ‘positive traits affirmation’ condition were more likely to request a free sample of sunscreen than those in the control condition. The implications of these findings for self-affirmation theory and the development of effective health promotion campaigns are discussed.

Self-affirmation increases acceptance of health-risk information among UK adult smokers with low socioeconomic status.

This study reports an experiment designed to test whether self-affirmation can overcome defensive processing of risk information in a sample of UK adult smokers with low socioeconomic status. Participants (N = 57) were randomized to either a self-affirmation or control condition before reading a government-sponsored antismoking leaflet and completing measures of message acceptance, intention, and self-efficacy. Participants' subsequent behavior (taking leaflets) was recorded surreptitiously. Results showed that the manipulation significantly increased message acceptance, intention and behavior, and that the effects of the manipulation on behavior were mediated through message acceptance and intention. The practical and theoretical implications of the findings are discussed in relation to the possible use of self-affirmation manipulations to enhance the effectiveness of smoking cessation interventions.

Experimental manipulations of self-affirmation: A systematic review

The objective of this systematic review of studies using self-affirmation manipulations was to identify research gaps and provide information to guide future research. We describe study characteristics, categories of manipulations, and report effects on various dependent variables. Our search strategies yielded 47 eligible articles (69 studies). Manipulations varied by affirmation domain (values or personal characteristics), attainment (participant- or investigator-identified), and procedure (scale, essay, feedback, etc.). Most dependent variables were cognitive. Strong effects of self-affirmation were found for attitudes and persuasion/bias, but future work is needed for variables with mixed results including risk cognitions, intentions, and behavior. Suggestions and considerations for future research involving self-affirmation manipulations are discussed.
