Prior research has established positive outcomes of health optimism (appraising one's health as good despite poor objective health (OH)) and negative outcomes of health pessimism (appraising health as poor despite good OH), yet little is known about their contributors. We examined the role of psychosocial factors (life event stress, depression, dispositional optimism, perceived social support) in health realism (appraising health in accordance with OH), optimism and pessimism among 489 older men and women. We then accounted for the psychosocial factors when examining multiple health correlates of health realism, optimism and pessimism. Controlling for age, gender and income, regression results indicate that depression and social support were associated with less health optimism, while dispositional optimism was associated with greater health optimism among those in poor OH. Dispositional optimism was associated with less health pessimism and life event stress was associated with greater pessimism among those in good OH. Beyond the effects of the psychosocial factors, structural equation model results indicate that health optimism was positively associated with healthy behaviours and perceived control over one's health; health pessimism was associated with poorer perceived health care management. Health optimism and pessimism have different psychosocial contributors and health correlates, validating the health congruence approach to later life well-being, health and survival.  相似文献

One difficulty plaguing research on dispositional optimism and health is whether optimism and pessimism are bipolar opposites or constitute distinct constructs. The present study examined the Life Orientation Test to determine whether the two-factor structure is explained by method bias (due to measurement) or substantive differences. The authors compared three measurement models: bipolar, bivariate, and method artifact. Optimism and pessimism emerged as distinct constructs due to substantive differences. The authors also considered the validity of optimism and pessimism, examining their relations with psychological and physical health outcomes. Optimism and pessimism were more similar in relation to psychological health than to other health-related behavior or physical health outcomes. However, a strongly interpretable pattern for the relation of optimism and pessimism to the health outcomes did not emerge. Further research may benefit from considering optimism and pessimism as bivariate and also should consider the conceptual components and behavioral mechanisms specific to each variable.  相似文献

We examined whether dispositional optimism and pessimism (overall LOT-R and optimism and pessimism component scores) of 694 adults aged 24 and 27 were associated with socioeconomic status (SES) measured concurrently and in childhood at ages 3 and 6. SES measures included education, occupational status and unemployment, and income. Concurrent adulthood SES was associated with the overall LOT-R and optimism and the pessimism component scores. Childhood family SES predicted overall LOT-R and pessimism component scores, even after controlling statistically for the adulthood SES. Social mobility between SES of family of origin and current SES also influenced the scores. The current findings suggest that the foundation of dispositional optimism and pessimism is related to early SES of the family.  相似文献

Optimism and pessimism are associated with important outcomes including health and depression. Yet it is unclear if these apparent polar opposites form a single dimension or reflect two distinct systems. The extent to which personality accounts for differences in optimism/pessimism is also controversial. Here, we addressed these questions in a genetically informative sample of 852 pairs of twins. Distinct genetic influences on optimism and pessimism were found. Significant family-level environment effects also emerged, accounting for much of the negative relationship between optimism and pessimism, as well as a link to neuroticism. A general positive genetics factor exerted significant links among both personality and life-orientation traits. Both optimism bias and pessimism also showed genetic variance distinct from all effects of personality and from each other.  相似文献

This work shows the association between personality variables, such as cognitive and affective variables, and psychological adjustment, such as life satisfaction and depressive symptoms. Accordingly, this study assessed the role of outcome expectancies (optimism and pessimism) and affectivity (positive and negative affect) as a predictors of life satisfaction and depressive symptoms. A total of 458 students from the University Rovira i Virgili completed the scales LOT-R, PANAS, the Satisfaction with Life Scale and BDI. Path analysis results suggest that affectivity variables are more important to predict life satisfaction and depressive symptoms than outcome expectancies. Implications for future research are discussed.  相似文献

We tested the hypotheses that (1) high pessimism and low optimism (LOT-R overall and subscale scores) would predict high ambulatory blood pressure (ABP) level and 24-hour load (percentage of ABP values exceeding the pediatric 95th percentile) among healthy Black and White adolescents (n=201; 14-16 yrs) across 2 consecutive school days and (2) that the relationships for the pessimism and optimism subscales would show nonlinear effects. The hypotheses were confirmed for pessimism but not for optimism. The results suggest that high pessimism may have different effects than low optimism on ABP and that even moderate levels of pessimism may effect blood pressure regulation. These results suggest that optimism and pessimism are not the opposite poles on a single continuum but ought to be treated as separate constructs.  相似文献

Abstract

Background: While there is growing awareness of the need to support the physical and mental wellbeing of transgender people, some may be reluctant to seek help from healthcare professionals. Little is understood about the mechanisms that influence help-seeking behavior in this group.

Aims: This study aimed to compare transgender and cisgender participants in their likelihood to seek help for both physical and mental health conditions, and to explore whether this help-seeking behavior is predicted by a range of sociodemographic and psychological variables.

Methods: 123 participants living in Ireland (cisgender= 67; transgender= 56) completed a questionnaire which included demographic questions, as well as measures of optimism (LOT-R), self-esteem (RSES), psychological distress (GHQ-12), attitudes towards seeking psychological help (ATSPPH-SF), and attitudes towards seeking help for a physical health problem (Attitudes Towards Seeking Medical Help Scale- Action/Intervention subscale). Associations between predictor variables and mental and physical health seeking were explored using correlation analysis and stepwise regressions.

Results: Transgender participants were less likely to seek help for a physical health issue than cisgender participants, but did not differ in mental health help-seeking behaviors. Results suggest that this may be due to differences in optimism, self-esteem and psychological distress. Transgender participants had significantly lower optimism and self-esteem, which were two factors linked to poorer physical health seeking behaviors. Optimism also emerged as a significant predictor in mental health seeking behaviors.

Discussion: The lack of a significant difference for mental health help-seeking between the transgender and cisgender participants is encouraging, as it suggests that there is less stigma surrounding mental illness than expected, however findings also contradict previous findings suggesting that physical health is less stigmatized. This could be due to stigma relating to gender-specific healthcare and suggests that healthcare professionals should acknowledge the specific healthcare needs and concerns among transgender individuals.  相似文献

The Life Orientation Test and its revision include items tapping both the belief that good things will happen (optimism) and the belief that bad things will not happen (low pessimism). The present investigation addressed the relationship of optimism and pessimism from psychometric and substantive perspectives. Two variations of the LOT-R, one with standard items and one with extreme adverbs (e.g., “always”) removed, were administered to undergraduate (n = 971) and web-based samples (n = 2806). Although there was psychometric support for a bidimensional structure in both versions, only the revised version showed substantive differences in the correlations of optimism versus pessimism with personality criteria. The generic recommendation is to use the original, unidimensional scale.  相似文献

本研究以中文版生活定向测验(LOT-R)为例,使用CTCM和CTCU方法进行建模,旨在探讨中文表述的量表中是否存在项目表述效应以及影响项目表述效应的特质因素。采用中文版生活定向测验等量表组成的问卷对334名大学生进行测试。结果表明,中文版LOT-R存在项目表述效应,是一种反向题的项目表述效应,也可称为语言标签效应;在分离了反向题项目表述效应后,发现中文版LOT-R只存在乐观因子,而不再有悲观因子。这表明乐观-悲观同属于一种人格特质,而非两种不同的人格特质;反向题项目表述效应是一种结构性误差,会导致量表结构的扭曲。研究还发现担心错误和父母期望与反向题项目表述效应存在显著的负相关,表明越是担心错误或父母期望水平越高的被试,他们对反向题的项目表述效应(语言标签效应)越小。社会赞许性对反向题项目表述效应没有影响。  相似文献

Objective: We examined the independent association between dispositional optimism compared to dispositional pessimism and ideal cardiovascular health (defined by the American Heart Association).

Design: A prospective design with a study sample of 1113 participants aged 24–39 years from the longitudinal Young Finns Study.

Main outcome measures: Ideal cardiovascular health (comprised of seven ideal cardiovascular health metrics) was measured in 2001. The ideal cardiovascular health metrics were reassessed in 2007.

Results: Low pessimism rather than high optimism was a better predictor of ideal cardiovascular health in 2007. When examining the association between optimism and pessimism and the seven ideal cardiovascular health metrics in 2007 (BMI, diet, physical activity, smoking status, blood pressure, total cholesterol and plasma glucose), low pessimism predicted non-smoking status, ideal physical activity and eating a healthy diet, while high optimism was associated with eating a healthy diet.

Conclusion: Our findings suggest that low pessimism rather than high optimism is associated with ideal cardiovascular health, especially with health behaviours such as not smoking, being physically active and eating a healthy diet. Socio-economic status was the potential mediating or confounding factor. Future studies should examine the differential meaning of the optimism/pessimism concepts to further clarify their relation to health outcomes.  相似文献

The purpose of this investigation was to investigate the concurrent validity of the Life Orientation Test-Revised (LOT-R) (Scheier et al., 1994) and Optimism/Pessimism Scale (OPS) (Dember et al., 1989) by administering each questionnaire to the same group of participants. The 154 participants (84 men and 70 women) were volunteer university students enrolled in physical activity classes at a southeastern university. The questionnaires were counterbalanced to reduce possible bias due to taking one questionnaire before taking the other. Due to recent suggestions concerning scoring mechanisms for the LOT-R (Dember et al., 1989; Hummer, Dember, Melton & Schefft, 1992; Lightsey, 1996; Marshall and Lang, 1990) the instrument was scored to produce a unidimensional score and two subscale scores. The analysis suggested that the LOTR and OPS may not be measuring similar constructs. The results revealed that the LOT-R may be measuring “trait” optimism and pessimism, while the OPS may be measuring “state” optimism and pessimism. It was also suggested that future research investigate racial differences on these constructs.  相似文献

The study aimed to examine the psychometric properties of the Dutch Life Orientation Test-Revised for Adolescents (LOT-R-A), a self-report questionnaire assessing dispositional optimism, and to evaluate the two-factor structure (optimism, pessimism). The LOT-R-A and the questionnaires measuring well-being (MHC-SF-A) and psychological problems (SDQ) were completed by 459 Dutch adolescents (178 boys and 281 girls) between the ages of 11 and 18 years at baseline and 281 adolescents at a four-week follow-up. The results confirmed the two-factor structure (optimism, pessimism) of the LOT-R-A. The findings provided evidence of internal consistency of scores ranging from low to good, and evidence of good test-retest reliability of scores. Further, scores of optimism were cross-sectionally positively associated with scores of positive emotions and well-being and negatively with scores of psychological problems and negative emotions, providing evidence of convergent and divergent validity of optimism scores with emotions, well-being, and psychological problems. Lastly, scores of optimism were prospectively positively associated with scores of well-being and negatively with scores of psychological problems, providing evidence of criterion validity of optimism scores with well-being and psychological problems. Based on these findings it can be concluded that the LOT-R-A is a valid instrument to examine optimism among adolescents. Future research can help to elucidate the role of optimism in mental health interventions and can gather knowledge on how these interventions can be refined to optimally cultivate optimism during the developmental period of adolescence.  相似文献

The classic, well-cited study by Marshall et al. (1992) demonstrated that optimism correlates stronger with extraversion than does pessimism and pessimism correlates stronger with neuroticism than does optimism, and these results lent support to their claim that optimism and pessimism are two separate constructs. However, we argued that their results are likely the outcome of scale artefact caused by item valence (or item favorability). In an empirical study (N = 1016), we evaluated the correlation of optimism scores and pessimism scores with the most common measure of optimism - Life Orientation Test-Revised (LOT-R). As expected, when item valence effect was not controlled, we replicated the finding by Marshall et al. (1992) that optimism and pessimism show differential correlations with extraversion and neuroticism. After item valence was controlled such pattern of relationships was greatly reduced. Suggestions for future research to resolve the dimensionality debate for optimism-pessimism are discussed.  相似文献

The main aim of this research was to evaluate psychometric properties and dimensionality of the Serbian version of the Life Orientation Test-Revised (LOT-R). The sample consisted of 744 youths, with a mean age 18.68 years. Psychometric properties of the Serbian version of the LOT-R were found to be satisfactory. The total scale and both subscales (Optimism and Pessimism) had adequate internal consistency. Convergent validity was demonstrated by moderate correlations with well-being measures (positive and negative affect, life satisfaction, hope, self-efficacy, loneliness and general distress). The results of confirmatory factor analyses yielded two correlated dimensions reflecting optimism and pessimism, and provided support for the two-factor model of optimism. The results of simultaneous multiple regression analyses demonstrated that both optimism and pessimism contributed uniquely to various indicators of well-being. Implications and directions for future research were discussed.  相似文献

The Life Orientation Test (LOT-R) is the most intensively used instrument for the assessment of optimism, but empirical evidence of its psychometric quality in Latin America is lacking. The aim of this study was to test psychometric properties of this questionnaire based on a representative sample of the general population of Colombia (N = 1,500). Confirmatory factor analyses confirmed the bi-dimensionality of the questionnaire with two factors, namely Optimism and Pessimism. The sum scores of the optimism and pessimism subscale correlated with r = ?.12. Convergent validity aspects were studied by correlating LOT-R values with anxiety, depression, quality of life, fatigue, mental health, hopelessness, and self-efficacy. Optimism was more strongly correlated with these variables than pessimism. Normative data and mean values for both genders and different age groups are given. Generally, there were only small age and gender effects. Compared to the German norm data, the Colombian participants scored on average one scale point higher in the dimension of optimism. In summary, the LOT-R in its Spanish version is an appropriate and practical tool for screening purposes in individual diagnostics and epidemiological research in Latin American samples.  相似文献

To explore the associations between religiosity, health, and psychopathology, samples of 460 Kuwaiti and 274 American college students were recruited. Religiosity, pessimism, anxiety, obsession-compulsion, death obsession, and ego-grasping were significantly higher among the Kuwaitis than among their American counterparts. On the other hand, self-ratings of mental health and optimism were significantly higher among the Americans than their Kuwaiti counterparts. Religiosity was significantly and positively associated with ratings of physical health, mental health, and optimism (both countries), and negatively with pessimism, anxiety, suicidal ideation, and ego-grasping (Kuwaitis), and pessimism and suicidal ideation (Americans). A factor analysis of the correlational matrix yielded in both countries two independent factors labeled “Normality vs. psychopathology”, and “Religiosity, health, and optimism”. Backward multiple regressions revealed that the main predictors of religiosity were mental health, optimism and physical health positively, and obsession-compulsion and ego-grasping negatively in Kuwaitis; and optimism positively and anxiety, and suicidal ideation negatively in Americans. By and large, those who consider themselves as religious were more healthy and optimistic, and obtained lower scores on psychopathology in both countries.  相似文献

OBJECTIVE: The premise that pessimistic health appraisals compromise well-being whereas optimistic appraisals are compensatory was examined in a longitudinal study of 232 community-dwelling older adults (ages 79-98 years). DESIGN: Subjective health (SH) appraisals were contrasted with objective health (OH) to identify realists, whose ratings were congruent (SH = OH), distinguishing them from health pessimists (SH < OH) and health optimists (SH > OH), whose ratings were incongruent. Analyses of covariance were used to examine group differences 2 years later on well-being and health care. MAIN OUTCOME MEASURES: Outcome measures were psychological well-being (life satisfaction, positive and negative emotions), functional well-being (objective and perceived physical activity, activity restriction), and health care (health care management, hospital admissions, length of hospital stays). RESULTS: Compared with realists, pessimists had significantly poorer outcomes and optimists had better outcomes. Because perceived control (PC) was weaker among pessimists and stronger among optimists, supplemental analysis determined whether PC differences explained these findings. When accounting for PC, many pessimism and optimism effects became nonsignificant, yet effects on functional well-being remained unchanged. CONCLUSION: Findings have implications for older adults at risk of functional decline.  相似文献
