Social Comparison of Health Risks: Locus of Control,the Person-Positivity Bias,and Unrealistic Optimism1

People typically attribute lower health risks to themselves than to others, a phenomenon referred to as unrealistic optimism. The present study tested the person positivity bias as a previously unexamined explanation of the phenomenon and analyzed the relationship between unrealistic optimism and expectations of control. High-school students estimated their own and one of three other persons’(the average student's, a randomly chosen student's, or their best same-sex friend's) chances of getting health problems. They also filled out questionnaires measuring locus of control and health-protective behavior. In contrast with the person positivity explanation, unrealistic optimism was not restricted to the “average other” condition. However, unrealistic optimism was stronger in subjects with a more internal locus of control than in subjects with a rather external locus of control. An unpredicted effect of estimation order was observed: Unrealistic optimism was stronger in subjects who estimated the comparison person's risks first than in subjects who started with own risks. This effect can be understood in terms of Codol's observation that people perceive others as more similar to themselves than they themselves are to others.     

Effects of fear on risk and control judgements and memory: Implications for health promotion messages

Health promotion messages that evoke fear are often used to decrease unrealistic optimism regarding risks, convince people to control their behaviour, and make risks memorable. The relations among emotions, risk and control judgements, and memory are not well understood, however. In the current study, participants (N = 94) were assigned to fearful, angry, happy, or neutral emotion-elicitation conditions. They then rated the likelihood of experiencing 15 negative and 15 positive matched outcomes and rated their degree of control over each outcome. A surprise memory test followed. Fear decreased unrealistic optimism, but the greater the intensity of fear reported the less control participants believed they had over outcomes. Fear also led to poorer memory for outcomes. Across all participants, the lower their ratings of optimism and control concerning outcomes, the less likely they were to recall them. Implications for the use of emotionally evocative material in health promotion messages are discussed.     

Self-Favoring Biases, Self-Presentation, and the Self-Other Asymmetry in Social Comparison

ABSTRACT The relationship between self-favoring biases in social comparison, favorable self-presentation, and well-being and the self-other asymmetry effect was examined. Participants gave comparative chance estimations and trait ratings for positive and negative future events and traits. One-half of the participants compared themselves to the average other, while the remainder compared the average other to themselves. All participants completed measurements of two types of desirable responding (self-deception and impression management) and of subjective well-being. Participants who compared themselves to another showed stronger unrealistic optimism and illusory superiority effects for positive (but not for negative) future events und traits than participants comparing another to themselves, demonstrating a self-other asymmetry effect. Unrealistic optimism and illusory superiority concerning positive attributes were related to self-deception, while unrealistic optimism and illusory superiority concerning negative attributes were related to impression management. The relative independence of “positive” and “negative” self-favoring biases was further demonstrated by their differential relationship with self-esteem and subjective well-being.     

My Child Is Better Than Average: The Extension and Restriction of Unrealistic Optimism1

The purpose of the current study was to determine whether parents make unrealistic evaluations of children and what factors predict these evaluations. Parents of 5‐ and 6‐year‐olds rated their child's risk for various positive and negative outcomes, temperament, and health and behavior problems. Parents also completed an adult attachment measure. Parents appeared to give relatively little consideration to realistic constraints when predicting their child's future. Parents scoring higher on attachment avoidance were less optimistic that their child would attain positive outcomes and avoid negative outcomes, consistent with the view that optimism is a motivated phenomenon. Greater child internalizing behaviors also were associated with less parental optimism for positive outcomes. Findings have implications for the delivery of health messages to parents.     

Testing Hypotheses Distilled from Four Models of the Effects of Health-Related Social Control

This study distilled and tested hypotheses derived from four models of the effects of social control on affect and health behavior among 401 college students involved in heterosexual dating relationships. Each model received at least some support. Consistent with the dual effects model, social control strategies predicted both health behavior change and negative affect. In accord with the domain-specific model, positive social control was related to positive affect and negative social control was related to negative affect. In partial support of the mediational model, positive social control exerted both a direct and an indirect effect via positive affect on health behavior change and negative social control exerted both a direct and an indirect effect via negative affect on hiding unhealthy behavior. As predicted by the contextual model, quality of dating relationship moderated the influence of positive and negative social control on hiding unhealthy behavior.     

Self appraisal and behavioural activation in the prediction of hypomanic personality and depressive symptoms

Hypomanic personality is characterised by increased positive mood and energy but also more depression and greater risk of bipolar disorder. It is linked with positive self-appraisals for hypomania-relevant events and Behavioural Activation System (BAS) sensitivity such that hypomanic individuals tend preferentially towards goal-related activities. This study investigated relationships between positive and negative self-appraisal and BAS functioning and hypomanic personality and depressive symptoms. Participants (N = 231) completed measures of hypomanic personality, mood symptoms, dysfunctional attitudes, self-appraisal and behavioural activation/inhibition.Positive but not negative self-appraisal contributed to prediction of hypomanic personality as did higher BAS fun seeking and lower Behavioural Inhibition System (BIS) scores. Conversely, negative self-appraisal was positively predictive of current depressive mood, whilst BAS reward responsiveness was negatively predictive. There are specific relationships between positive and negative appraisal styles and hypomanic personality and depressive mood, respectively. The findings of complimentary contributions from appraisal style, BAS and BIS to prediction of hypomanic personality are relevant to developing a better understanding of risk factors for bipolar disorder.     

Effects of mood on self-appraisal of health status

Two experiments investigated the effects of temporary mood on the self-perception of health status. In Experiment 1, participants viewed one of two videotapes designed to induce either positive or negative mood. Under the guise of a second experiment, they were asked to imagine an illness-related scenario and to provide judgments concerning their health status. As predicted, positive-induction participants judged their health more favorably than negative-induction participants. Experiment 2 examined the mediating role of illness-relevant thinking in this mood effect. After seeing one of the two mood-induction tapes, some participants were asked to imagine either an illness-related or illness-unrelated scenario. A third group was given no instructions concerning imagination. As predicted, the relative effect of negative mood on health appraisal was attenuated only among those who imagined a scenario unrelated to health. Furthermore, the pattern of symptom recall data mirrored the self-appraisal findings. The data are consistent with the notion that negative mood can affect subjective appraisals of health by increasing the accessibility of illness-related memories. Implications for diagnostic practice are explored.     

Lateral asymmetry of personal optimism

By combining models of cerebral emotional asymmetry and unilateral hemispheric activation, it was hypothesized that orienting to the right would produce greater personal optimism about future events than would orienting toward the left. This was supported significantly in two experiments which differed from each other in their manipulations, hypothetical future events, means of responding, and settings. The results supported previous research on unrealistic optimism and extended the concept to show the effect of induced lateral orientation. It was proposed that this effect is mediated by mood, and possibly by perceived control, and that this methodology can be extended to other behaviors which have proven amenable to mood manipulation.     

The Effect of Mood and Social Outlook on Hypothetical Juridic Decisions1

Data are reported for a laboratory experiment which examines both the impact of information about remote social events on judgments of defendants' guilt or innocence in two court cases and the roles of cognitive and affective elements in mediating these judgments. Subjects were exposed to one of four pretested news bulletins which covaried cognitive factors (positive or negative social information) and affective ones (positive or negative mood stimuli). In accord with previous findings, the results indicate that social information and the changes in social outlook that it caused were of primary importance in altering subjects' judgments about defendants. Subjects who heard positive social information in radio newscasts were more lenient in their judgments of defendants than were those who heard negative social information. Additional findings pertaining to the mediators of this effect suggest that positive mood amplified the impact of social information whatever its direction, while negative mood attenuated it.     

Unrealistic Pessimism

Abstract

Various data suggest that individuals tend to be unrealistically optimistic about the future. People believe that negative events are less likely to happen to them than to others. The present study examined if the optimistic bias could be demonstrated if a threat is not (as it has been researched up to the present) potential, incidental, and familiar, but real, common, and unfamiliar. The present research was conducted after the explosion at the atomic power station in Chernobyl, and it was concerned with the perception of threat to one's own and to others' health due to consequences of radiation. The female subjects believed that their own chance of experiencing such health problems were better than the chances of others. Thus, in these specific conditions, unrealistic optimism was not only reduced but the reverse effect was obtained: unrealistic pessimism.     

Gender differences in unrealistic optimism about marriage and divorce: are men more optimistic and women more realistic?

Two studies (n = 497) examine gender differences in "unrealistic optimism" in beliefs of marriage using a Taiwanese population. Unrealistic optimism is defined as the beliefs that positive (negative) events are more (less) likely to happen to one's self versus others. Although the bias is robust, it has been shown to be lower among people with an interdependent orientation, specifically those from a collectivist culture (e.g., Taiwan). We find that the unrealistic optimism bias is stronger (Study 1) and more resilient to change when base rates are provided (Study 2) for men as compared to women. Results are consistent with the interpretation that men have a less relationally interdependent self-construal than women. Theoretical implications for unrealistic optimism, cross-cultural psychology, as well as gender differences are discussed.     

What do people think about when answering questionnaires to assess unrealistic optimism about skin cancer? A think aloud study

There is little information concerning what people think about when completing questionnaires that assess perceptions of risk, and even less for questionnaires assessing unrealistic optimism. The thoughts of 40 participants who displayed unrealistic optimism about risks of skin cancer were elicited using think aloud methods, when completing both direct and indirect ratings of unrealistic optimism. The most common thoughts overall concerned exposure to the sun, and features such as skin colouring. Thoughts concerning prevalence, reasons for risky behaviour and admissions of ignorance were more common for indirect measures of unrealistic optimism than for direct measures. The direct unrealistic optimism measures yielded more optimistic ratings for those participants who did not mention symptoms or signs of skin damage, and those who mentioned thoughts about prevalence. Participants seem to be drawing upon different sources of information when completing superficially similar direct and indirect measures of unrealistic optimism, which may explain why these measures are usually only modestly associated. People do not seem to think about numerical probabilities when estimating risk, but instead appear to focus on issues such as exposure to risk, and concrete bodily symptoms and signs. This may at least partially explain why attempts to influence behaviour by providing probabilistic information are generally unsuccessful.     

'Paradoxical' Mood Effects on Creative Problem-solving

Two studies examined the influence of various affective states on creative problem-solving. In Study 1, individual differences in mood were measured using an adjective checklist immediately prior to task performance. Insight problems were then employed to measure creative problem-solving. Performance was compared with that obtained for analytic problem-solving tasks that were included as contrast variables. Results showed that positive mood led to significantly poorer creative problem-solving performance. No link was found between negative mood and general arousal. Performance on the contrasting analytic problem-solving tasks was negatively related to anxiety, but not to positive or negative mood states. In Study 2, the procedure was followed with the addition of experimentally induced mood states. The results obtained in Study 1 for mood ratings were replicated. In the induced mood conditions, negative mood significantly facilitated creative problemsolving performance relative to induced neutral mood, which in turn was better than the control condition. The poorest performance was obtained in the positive mood condition. The results are discussed in the context of contrasting theories of the relationships between mood and problem-solving performance.     

Helping is not enough: Recipient's reactions to aid as a function of positive and negative information about the self

The present research investigated the effects of experimentally induced positive and negative feedback about the self on the recipient's subsequent reactions to aid. In line with a consistency prediction, subjects given positive feedback who later received aid had lower mood ratings and less favorable self-evaluations than those who were given positive feedback but no subsequent help. Conversely, subjects given negative feedback who later received aid had higher mood ratings and more positive self-evaluations than those who were given negative feedback but no subsequent help. Subjects' evaluations of another individual were characterized by aid main effects, which indicate that an other who helped was evaluated more favorably than an other who did not help. The conceptual and applied implications of these results are discussed.     

The mystery of the Polish soul. B. W. Johnson's effect à rebours

Studies conducted in Poland replicated a not very-well known effect discovered by B. W. Johnson (1937). In his study students estimated their mood on several successive days each time comparing it to the mood they usually have. The results revealed a peculiar positive bias in that the students usually defined their mood as ‘better than usual’. Johnson's study was replicated in Poland, where demonstration of optimism is not a cultural norm. The results suggest that Polish subjects ‘usually define their mood as worse than usual’. The generalization and limitation of this negative bias is discussed in the light of the Pollyanna Principle and related empirical studies involving Polish subjects.     

Imagining and Explaining Hypothetical Scenarios: Mediational Effects on the Subjective Likelihood of Health‐Related Outcomes1

Imagining and explaining hypothetical events have been shown to increase the subjective likelihood of those events occurring. At the same time, it has been suggested that reducing unrealistic optimism about health risks (i.e., increasing the subjective likelihood of negative health outcomes) might motivate health‐protective behavior. In exploring the implications of these issues for health‐promotion goals, 2 experiments (Ns= 334 and 328) involving postal questionnaires are reported in which attempts are made through the use of imagine‐and‐explain scenarios to manipulate the subjective likelihood of a negative outcome (heart disease) and of a positive outcome (reducing fat consumption). The greater success of the manipulation of dietary change expectations than of heart disease expectations suggests the potential benefits of focusing directly on planning goal strategies in relation to health beneficial behaviors.     

The Role of Temporal Comparison, Social Comparison, and Direct Appraisal in the Elderly's Self-Evaluations of Health

Elderly persons (n= 91) were interviewed about self- perceptions of physical health and the contribution of social comparison, temporal comparison, and direct appraisal to these judgments. Consistent with previous studies, self-assessments tended to be mainly positive (67% reported their health as “good” or “excellent”), though tempered somewhat by the individual's objective physical condition (i.e., number of chronic diseases or disabilities). Independent of objective health, respondents' ratings were more negative if they mentioned thinking about past or anticipated health. Respondents were more concerned about their health if they thought about their past or anticipated health or mentioned comparing with a specific other person. Direct feedback had no effect on health ratings. Among those who reported social comparison, ratings were more positive when worse-off others were mentioned. Temporal comparisons may be associated with more negative ratings because the elderly's past health is likely to have been better and their future (anticipated) health can be expected to become worse. If using temporal and social comparison information is associated with more negative assessments then what accounts for the generally positive self-assessments? We propose that the elderly compare themselves with a cognitively constructed stereotypical standard of the frail elderly rather than with a specific other. Because few elderly actually “fit” this stereotype, most elderly feel they are doing well.

Observer ratings of health and sickness: can other people tell us anything about our health that we don't already know?

After administering interviews covering health conditions, physical limitations, optimism, and affect to 851 older adults, interviewers rated the health and sickness of the interviewees. Observers' ratings of health and sickness were more highly correlated with the severity of participants' self-reported health conditions than were participants' self-ratings of health. This finding is likely attributable to participants' self-ratings of health being more highly correlated with their optimism and positive affect than the observers' ratings. Participants rated as sicker and less healthy at baseline were at a 3 times greater risk for mortality over 114 months. This association was independent of participants' self-rated health as well as demographics, self-reported health conditions, years of smoking, physical limitations, body mass index, optimism, and affect.     

Perceived stress management skill mediates the relationship between optimism and positive mood following radical prostatectomy.

This study evaluated relations among optimism, perceived stress management skills (PSMS),and positive mood in 46 men who had surgical treatment for localized prostate cancer. The authors found that optimism, PSMS, and positive mood scores were positively correlated. Positive mood was unrelated to demographic and disease-related control variables. In a hierarchical regression model controlling for PSMS, the relationship between optimism and positive mood became nonsignificant, whereas PSMS remained a correlate of positive mood. Results suggest that the relationship between optimism and positive mood may be mediated by belief in being able to use stress management techniques effectively.
