Does High Self-Esteem Cause Better Performance, Interpersonal Success, Happiness, or Healthier Lifestyles?

Roy F. Baumeister; Jennifer D. Campbell; Joachim I. Krueger; Kathleen D. Vohs

Self-esteem has become a household word. Teachers, parents, therapists, and others have focused efforts on boosting self-esteem, on the assumption that high self-esteem will cause many positive outcomes and benefits—an assumption that is critically evaluated in this review. Appraisal of the effects of self-esteem is complicated by several factors. Because many people with high self-esteem exaggerate their successes and good traits, we emphasize objective measures of outcomes. High self-esteem is also a heterogeneous category, encompassing people who frankly accept their good qualities along with narcissistic, defensive, and conceited individuals. The modest correlations between self-esteem and school performance do not indicate that high self-esteem leads to good performance. Instead, high self-esteem is partly the result of good school performance. Efforts to boost the self-esteem of pupils have not been shown to improve academic performance and may sometimes be counterproductive. Job performance in adults is sometimes related to self-esteem, although the correlations vary widely, and the direction of causality has not been established. Occupational success may boost self-esteem rather than the reverse. Alternatively, self-esteem may be helpful only in some job contexts. Laboratory studies have generally failed to find that self-esteem causes good task performance, with the important exception that high self-esteem facilitates persistence after failure. People high in self-esteem claim to be more likable and attractive, to have better relationships, and to make better impressions on others than people with low self-esteem, but objective measures disconfirm most of these beliefs. Narcissists are charming at first but tend to alienate others eventually. Self-esteem has not been shown to predict the quality or duration of relationships. High self-esteem makes people more willing to speak up in groups and to criticize the groups approach. Leadership does not stem directly from self-esteem, but self-esteem may have indirect effects. Relative to people with low self-esteem, those with high self-esteem show stronger in-group favoritism, which may increase prejudice and discrimination. Neither high nor low self-esteem is a direct cause of violence. Narcissism leads to increased aggression in retaliation for wounded pride. Low self-esteem may contribute to externalizing behavior and delinquency, although some studies have found that there are no effects or that the effect of self-esteem vanishes when other variables are controlled. The highest and lowest rates of cheating and bullying are found in different subcategories of high self-esteem. Self-esteem has a strong relation to happiness. Although the research has not clearly established causation, we are persuaded that high self-esteem does lead to greater happiness. Low self-esteem is more likely than high to lead to depression under some circumstances. Some studies support the buffer hypothesis, which is that high self-esteem mitigates the effects of stress, but other studies come to the opposite conclusion, indicating that the negative effects of low self-esteem are mainly felt in good times. Still others find that high self-esteem leads to happier outcomes regardless of stress or other circumstances. High self-esteem does not prevent children from smoking, drinking, taking drugs, or engaging in early sex. If anything, high self-esteem fosters experimentation, which may increase early sexual activity or drinking, but in general effects of self-esteem are negligible. One important exception is that high self-esteem reduces the chances of bulimia in females. Overall, the benefits of high self-esteem fall into two categories: enhanced initiative and pleasant feelings. We have not found evidence that boosting self-esteem (by therapeutic interventions or school programs) causes benefits. Our findings do not support continued widespread efforts to boost self-esteem in the hope that it will by itself foster improved outcomes. In view of the heterogeneity of high self-esteem, indiscriminate praise might just as easily promote narcissism, with its less desirable consequences. Instead, we recommend using praise to boost self-esteem as a reward for socially desirable behavior and self-improvement.

Self-Concept Clarity: Measurement, Personality Correlates, and Cultural Boundaries

Jennifer D. Campbell; Paul D. Trapnell; Steven J. Heine; Ilana M. Katz; Loraine F. Lavallee; Darrin R. Lehman

Self-concept clarity (SCC) references a structural aspect oftbe self-concept: the extent to which selfbeliefs are clearly and confidently defined, internally consistent, and stable. This article reports the SCC Scale and examines (a) its correlations with self-esteem (SE), the Big Five dimensions, and self-focused attention (Study l ); (b) its criterion validity (Study 2); and (c) its cultural boundaries (Study 3 ). Low SCC was independently associated with high Neuroticism, low SE, low Conscientiousness, low Agreeableness, chronic self-analysis, low internal state awareness, and a ruminative form of self-focused attention. The SCC Scale predicted unique variance in 2 external criteria: the stability and consistency of self-descriptions. Consistent with theory on Eastern and Western selfconstruals, Japanese participants exhibited lower levels of SCC and lower correlations between SCC and SE than did Canadian participants.

Self-esteem and clarity of the self-concept.

Jennifer D. Campbell

This article examines the association between evaluative and knowledge components of the self. Four studies tested the hypothesis that the self-concepts of low-self-esteem (LSE) people are characterized by less clarity or certainty than those of high-self-esteem (HSE) people. LSE Ss exhibited less extremity and self-reported confidence when rating themselves on bipolar trait adjectives (Study 1), less temporal stability in their trait ratings over a 2-month interval (Study 2), less congruence between their self-concepts and their subsequent perceptions of situation-specific behavior and memory for prior behavior (Study 3), and less internal consistency, lower self-rated confidence, and longer reaction times when making me/not me responses to pairs of opposite traits (Study 4). Alternative accounts of the results and the implications of self-concept clarity for understanding the pervasive impact of self-esteem on behavior are discussed.

Similarity and uniqueness: The effects of attribute type, relevance, and individual differences in self-esteem and depression.

Jennifer D. Campbell

On the basis of a self-validation perspective, it was predicted that distortions in consensus estimates would vary as a function of attribute type (opinions versus abilities), relevance of the attribute, and individual differences in self-esteem and depression. Students rated themselves on seven opinion and ability dimensions using 5-point Likert scales. Then they estimated the percentage of the other students who held each opinion/ability position, and rank ordered the opinions/abilities for personal relevance. Absolute and directional accuracy scores were computed (comparing estimated percentages with actual percentages in the sample), as well as false consensus (FCE) scores (comparing estimates of subjects holding and not holding a particular position). Subjects overestimated consensus for their opinions and low abilities, but underestimated consensus for their high abilities. Although subjects exhibited a larger FCE on opinions than abilities, there was a reliable FCE for both attributes. Relevance affected the magnitude of these biases. Higher opinion relevance was associated with increased accuracy, lower FCE scores, and smaller overestimates. Higher ability relevance was associated with decreased accuracy, greater overestimation on low abilities, and greater underestimation on high abilities. Finally, low self-esteem and depressed subjects overestimated consensus on opinions and underestimated consensus on abilities less than high self-esteem and nondepressed subjects.

Who am I? The Role of Self-Concept Confusion in Understanding the Behavior of People with Low Self-Esteem

Jennifer D. Campbell; Loraine F. Lavallee

Research on self-esteem has had a long, prolific history in psychology. Although several reasons could be cited for the topic’s popularity, the most important, in our view, is that self-esteem has been shown to have a pervasive and powerful impact on human cognition, motivation, emotion, and behavior. Research has demonstrated, for example, self- esteem effects in such diverse areas as competition, conformity, attraction, causal attribution, achievement, helping, and coping with stressful life events (DeLongis, Folkman, & Lazarus, 1988; Wells & Marwell, 1976; Wylie, 1974, 1979). Despite decades of empirical and theoretical activity, however, little consensus has been achieved with regard to the locus of these effects. In particular, as reflected in the title of this volume, there is still considerable debate surrounding the specific characteristics of people low in trait self-esteem that somehow cause them to respond in ways that are often detrimental to their psychological well-being (Taylor & Brown, 1988).

Social support and social strain among husbands and wives: a multilevel analysis.

Anita DeLongis; Martha J. Capreol; Susan Holtzman; Tess O'brien; Jennifer D. Campbell

In response to recent calls in the literature for within-person examinations of social support processes over time, this study explores the relationships of spousal support, spousal strain, and well-being among husbands and wives, both within the same day and across days. Eighty-three couples were interviewed and completed a structured diary twice daily for 1 week. The results of multilevel hierarchical modeling suggest that both spousal support and spousal strain made significant, independent contributions to concurrent negative affect, although only spousal support was a significant predictor of next-day negative affect. Spousal strain interacted with spousal support to predict next-day negative affect. Direct and moderating effects of perceived marital adjustment on negative affect were discussed.

Ambivalence over emotional expression and well-being: Nomothetic and idiographic tests of the stress-buffering hypothesis.

Ilana M. Katz; Jennifer D. Campbell

Nomothetic and idiographic relations between ambivalence over emotional expression (AEQ; King & Emmons, 1990) and well-being were examined in a 4-month study with an interim 2-week diary component. Nomothetic and idiographic analyses both revealed that AEQ was related to psychological health but not to physical well-being. The nomothetic test of stress-buffering showed that AEQ was more predictive of depression among Ss who had experienced higher levels of positive life-event stress. In contrast, the idiographic test of stress-buffering revealed that Ss higher in AEQ exhibited less covariation between daily stress and negative affect over time. It is proposed that AEQ may reflect 2 types of emotional vulnerability - emotional reactivity and emotional perseveration - and the implications of this distinction for testing the stress-buffering hypothesis are discussed

Abdulwahab Naser Al-Isa; Jennifer D. Campbell; Ediriweera B. R. Desapriya; Namal Wijesinghe

Our aim was to explore the social and health factors that are associated with the level of physical activity among Kuwaiti college students. A random sample of 787 students (48% males and 52% females) was chosen and weight and height were measured to obtain body mass index (BMI, kg/m2). Associated social and health factors were obtained using a questionnaire. Those reporting being physically inactive numbered 354 and the remaining 433 were active. Obesity among males was 13% and was 10.5% among females. The social and health factors that were found to be significantly associated with physical activity among the students were gender (P < .001), marital status (P < .05), BMI category (obese or nonobese) (P < .05), last dental and health checkup (P < .01), desiring a higher degree (P < .001), and countries preferred for visiting (P < .01). Males significantly exceeded females in the practice of physical activity. In conclusion, behavioural modifications, intervention studies, and health education touting the benefits of being physically active should be instituted to increase the practice of sports and other physical activities in order to control and decrease obesity-related morbidity and mortality.

Factors associated with overweight and obesity among Kuwaiti elementary male school children aged 6-10 years

Abdulwahab Naser Al-Isa; Jennifer D. Campbell; Ediriweera B. R. Desapriya

Background. Childhood obesity is becoming a global epidemic which may result in increased morbidity and mortality during young adulthood. Objectives. To identify factors associated with overweight and that of obesity among Kuwaiti elementary male school children aged 6–10 years. Methods. Weights and heights of 662 students at a randomly selected school were collected to obtain body mass index (BMI). Results. The prevalence of overweight and obesity among the students were 20.2% and 16.8%, respectively. There were a variety of factors associated with overweight and obesity; however, having one or more obese brother, an unemployed father, or a high (>11) number of persons living at home was significantly associated with higher risk of overweight and obesity. Increased age and school level as well as having a chronic disease were associated with the risk of overweight. Conclusion. Health education programs for families should be implemented to help control overweight and obesity in Kuwaiti children.

Factors Associated With Overweight and Obesity Among Kuwaiti Men

Abdulwahab Naser Al-Isa; Jennifer D. Campbell; Ediriweera B. R. Desapriya

Obesity is a global epidemic and has become a critical issue in Gulf countries such as Kuwait. The objective of this study is to assess the factors that are associated with overweight and obesity among Kuwaiti adult men. Weights and heights of a random sample of 464 men and their companions were collected to obtain body mass index (BMI). The overall levels of overweight and obesity were 48.5% and 19.8%, respectively. Logistic regression analysis of significantly associated factors revealed that factors contributing to risk of overweight and obesity included increasing age, having an obese mother or brother(s) and/or other obese relatives, having a lower grade point average, not being physically active, and being in poor health. Having a higher income and feeling tired were risk factors for obesity only. Family history is an important predictor of overweight and obesity in Kuwaiti men; however, this study identified several modifiable factors. It is recommended that factors that contribute to the development of overweight and obesity in Kuwait be targeted with behavioral change and/or health education interventions.
