Interactive effects of extraversion, neuroticism, and social relationships on subjective well-being.

Previous research has indicated that there is a relation between extraversion and subjective well-being (SWB), and that the sociability component of extraversion primarily accounts for this relation. Interactive effects of extraversion and social relationship variables on SWB were hypothesized and found in Study 1 using the Extraversion scale from the 16 PF, the Well-Being subscale of the Differential Personality Questionnaire, and several social relationship scales administered to 291 college students. Several multiple regression analyses indicated that strength of social relationships was a strong predictor of SWB only for introverted individuals. Study 2 replicated these findings with the Eysenck Personality Inventory and revealed important interactive relations between extraversion, neuroticism, and social relationships in predicting SWB. A strong relationship between extraversion and SWB occurred only among individuals who were highly neurotic or who had poor social relationships.

Social influences in motivated drinking among college students.

This study tested whether drinking motives mediate the relation between personality and alcohol use and whether these predictors affected drinking in these individuals' friends. College students and their friends participated in the study as dyads (n=43 dyads, 86 participants). Each person completed surveys and a 28-day experience sampling protocol. Structural equation analyses found that (a) social motives mediated the relation between extraversion and alcohol outcomes, (b) coping motives mediated the relation between neuroticism and alcohol outcomes, and (c) enhancement motives mediated the relation between extraversion and alcohol outcomes. Moreover, young adults' alcohol use, but not their problem use, was influenced by their own drinking motives as well as the drinking motives of their best friends.

Perceived social isolation makes me sad: 5-year cross-lagged analyses of loneliness and depressive symptomatology in the Chicago Health, Aging, and Social Relations Study.

We present evidence from a 5-year longitudinal study for the prospective associations between loneliness and depressive symptoms in a population-based, ethnically diverse sample of 229 men and women who were 50–68 years old at study onset. Cross-lagged panel models were used in which the criterion variables were loneliness and depressive symptoms, considered simultaneously. We used variations on this model to evaluate the possible effects of gender, ethnicity, education, physical functioning, medications, social network size, neuroticism, stressful life events, perceived stress, and social support on the observed associations between loneliness and depressive symptoms. Cross-lagged analyses indicated that loneliness predicted subsequent changes in depressive symptomatology, but not vice versa, and that this temporal association was not attributable to demographic variables, objective social isolation, dispositional negativity, stress, or social support. The importance of distinguishing between loneliness and depressive symptoms and the implications for loneliness and depressive symptomatology in older adults are discussed.

Creativity, divergent thinking, and openness to experience.

Test scores of divergent thinking obtained between 1959 and 1972 were correlated with a variety of personality measures administered since 1980. In this sample of 268 men, divergent thinking was consistently associated with self-reports and ratings of openness to experience, but not with neuroticism, extraversion, agreeableness, or conscientiousness. Both divergent thinking and openness were also modestly correlated with Gough's (1979) empirically derived Creative Personality Scale. Several other personality variables mentioned in the literature were also examined; those that were associated with divergent thinking were also generally correlated with openness. These data suggest that creativity is particularly related to the personality domain of openness to experience. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Loneliness in everyday life: Cardiovascular activity, psychosocial context, and health behaviors.

Prior lab research revealed higher basal total peripheral resistance (TPR) and lower cardiac output (CO) in lonely than in nonlonely young adults. In this study, experience sampling was used to obtain ambulatory blood pressure; impedance cardiography; and reports of activities, appraisals, interactions, and health behaviors. Results confirmed that loneliness predicted higher TPR and lower CO during a normal day. Loneliness did not predict differences in time spent alone, daily activities, or health behaviors but did predict higher stress appraisals and poorer social interactions. Independent of loneliness, interaction quality contributed to TPR. Loneliness differences were not mediated by depressed affect or neuroticism. Social support mediated loneliness differences in stress and threat. Concomitants of loneliness were comparable for men and women. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Coping in stressful episodes: The role of individual differences, environmental factors, and situational characteristics.

This article examines individual differences (extraversion and neuroticism), environmental factors (social support and work demand), and situational characteristics (type of stressful episode and its perceived importance) as predictors of three self-report measures of coping (general coping, direct coping, and suppression) derived from the Ways of Coping Questionnaire. The data analyzed were collected from 135 first-year female student nurses. Individual differences were assessed prior to exposure to the ward environment, and information about stressful episodes was obtained during the initial period of nursing practice. Multiple regression analyses showed that individual differences and environmental and situational factors were significant predictors of the coping scores and that patterns of main and interactive effects were different for each type of coping. For direct coping and suppression, predicted interactions across person, environmental, and situational variables contributed significantly to the explained variance. Curvilinear interactions between work demand and neuroticism were significant for both direct coping and suppression; interactions of social support and extraversion with perceived importance predicted direct coping; and interactions between neuroticism and extraversion and between work demand and importance predicted suppression.

Interactions in predicting mood from extraversion and neuroticism.

Many researchers have found evidence that, when only marginal distributions are examined, extraversion is related primarily to positive affect, whereas neuroticism is related primarily to negative affect. Recent findings have suggested that extraversion and neuroticism interact in predicting mood so that marginal relations could be misleading. The present study used extraversion (and its components, sociability and impulsivity) along with neuroticism in regression equations including interactive and curvilinear components to predict measures of positive and negative affect among 384 undergraduates. Results confirm earlier findings that extraversion and neuroticism interact in predicting both positive and negative affect. The interaction pattern was similar to previous findings: Both positive and negative affect were strongly related to extraversion only among neurotic Ss.

Personality and leader effectiveness: A moderated mediation model of leadership self-efficacy, job demands, and job autonomy.

The trait theory of leadership is advanced by a joint investigation of the mediating role of (a) leadership self-efficacy (LSE = leader's perceived capabilities to perform leader roles) in linking neuroticism, extraversion, and conscientiousness with leader effectiveness and (b) the moderating role of job demands and job autonomy in influencing the mediation. Using K. J. Preacher, D. D. Rucker, and A. F. Hayes' (2007) moderated mediation framework, the authors tested the model (over a 2-year period) with matched data from 394 military leaders and their supervisors. Results showed that LSE mediated the relationships for neuroticism, extraversion, and conscientiousness with leader effectiveness. Moderated mediation analyses further revealed that LSE mediated the relationships for (a) all 3 personality variables for only those leaders with low job demands; (b) neuroticism and conscientiousness for only those leaders with high job autonomy; and (c) extraversion, regardless of a leader's level of job autonomy. Results underscore the importance of accounting for leaders' situational contexts when examining the relationships between personality, LSE, and effectiveness.

Loneliness, Social Network Size, and Immune Response to Influenza Vaccination in College Freshmen.

Antibody response to the influenza immunization was investigated in 83 1st-semester healthy university freshmen. Elevated levels of loneliness throughout the semester and small social networks were independently associated with poorer antibody response to 1 component of the vaccine. Those with both high levels of loneliness and a small social network had the lowest antibody response. Loneliness was also associated with greater psychological stress and negative affect, less positive affect, poorer sleep efficiency and quality, and elevations in circulating levels of cortisol. However, only the stress data were consistent with mediation of the loneliness-antibody response relation. None of these variables were associated with social network size, and hence none were potential mediators of the relation between network size and immunization response.

Social desirability scales: More substance than style.

Many psychologists still regard correlations with social desirability (SD) scales as evidence of the invalidity of measures, despite 20 yrs of research showing that this interpretation is usually unjustified. Although items or scales may be characterized as high or low in SD, there is little evidence that individuals differentially respond to this property when completing self-report questionnaires under normal instructional conditions. In an attempt to separate substance from style in SD scales, self-reports from 215 27–89 yr olds were compared to the external criterion of spouse ratings on a range of personality traits in the domains of neuroticism, extraversion, and openness to experience (the Neuroticism-Extraversion-Openness Inventory). When self-reports were "corrected" using scores from the Eysenck Personality Inventory Lie scale and the Marlowe-Crowne Social Desirability Scale, validity coefficients decreased in most cases. Both scales were substantively related to neuroticism and, to a lesser degree, to extraversion and closedness. Results suggest that correlations with SD scales should be given substantive rather than artifactual interpretations and that the widespread practice of correcting scores for lying, defensiveness, or SD should be questioned.

Evaluating stability and change in personality and depression

Critics have argued that personality factors believed to represent a vulnerability to depression are not stable and are therefore state dependent. However, conclusions regarding the stability of personality and the relation between personality and depression have been drawn (a) without differentiating relative stability among individual differences from absolute stability of change scores and (b) without explicitly modeling change in personality as a function of change in depression. The relation between neuroticism and depression was examined in a sample of depressed outpatients (N = 71) receiving a 5-week trial of pharmacotherapy. Measures of neuroticism and extraversion demonstrated both relative stability and absolute change, and changes in neuroticism and extraversion scores were modestly or not at all accounted for by changes in depression scores. Claims that personality scores are not stable and are state dependent must be reconsidered.     

Love, work, and changes in extraversion and neuroticism over time.

The present study examined individual differences in change in extraversion, neuroticism, and work and relationship satisfaction. Of particular interest were the correlations between changes. Data were from the Victorian Quality of Life Panel Study (B. Headey & A. Wearing, 1989, 1992), in which an overall 1,130 individuals participated (ages 16 to 70). Respondents were assessed every 2 years from 1981 to 1989. Four major findings emerged. (a) There were significant individual differences in changes in extraversion and neuroticism. (b) Change was not limited to young adulthood. (c) Development was systematic in that increased work and relationship satisfaction was associated with decreases in neuroticism and increases in extraversion over time; on average, the magnitude of the relation between changes in work and relationship satisfaction and traits was .40. (d) Cross-lagged models indicated traits had a greater influence on role satisfaction; however, marginal support emerged for work satisfaction leading to increased extraversion. Implications of correlated change are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)

Generalized and specific loneliness in early marriage.

38 husbands (mean age 26 yrs) and wives (mean age 23.8 yrs), married for an average of 35.8 mo and without children, independently completed a set of established measures of loneliness and of aspects of their marital relationship (e.g., UCLA Loneliness Scale). Significant levels of loneliness were reported by some Ss, and only modest correlations were found between the loneliness scores of husbands and wives. General and specific loneliness were related to marital attitudes, particularly less liking, less intimacy, and greater communication apprehension among husbands, and to less liking, less marital satisfaction, less love, and less self-disclosure among the wives. Scores of the spouses and spouse difference scores on several of these variables were also related to loneliness. Findings are discussed as pertaining to loneliness without social isolation and in relation to the quality of relationships.

Loneliness predicts reduced physical activity: Cross-sectional & longitudinal analyses.

Objective: To determine cross-sectional and prospective associations between loneliness and physical activity, and to evaluate the roles of social control and emotion regulation as mediators of these associations. Design: A population-based sample of 229 White, Black, and Hispanic men and women, age 50 to 68 years at study onset, were tested annually for each of 3 years. Main Outcome Measures: Physical activity probability, and changes in physical activity probability over a 3-year period. Results: Replicating and extending prior cross-sectional research, loneliness was associated with a significantly reduced odds of physical activity (OR = 0.65 per SD of loneliness) net of sociodemographic variables (age, gender, ethnicity, education, income), psychosocial variables (depressive symptoms, perceived stress, hostility, social support), and self-rated health. This association was mediated by hedonic emotion regulation, but not by social control as indexed by measures of social network size, marital status, contact with close ties, group membership, or religious group affiliation. Longitudinal analyses revealed that loneliness predicted diminished odds of physical activity in the next two years (OR = 0.61), and greater likelihood of transitioning from physical activity to inactivity (OR = 1.58). Conclusion: Loneliness among middle and older age adults is an independent risk factor for physical inactivity and increases the likelihood that physical activity will be discontinued over time.

Loneliness, attachment, and the perception and use of social support in university students.

This study examined factors related to family, social, and romantic loneliness in 173 undergraduate students (66 males, 107 females). Participants completed measures of attachment style, perceived availability of social support, use of social support coping, and loneliness. Results indicated that participants with greater attachment security reported lower levels of all types of loneliness compared to those with less attachment security, and this was partially mediated by perceived social support but not the use of social support coping. When examining underlying attachment constructs, a more positive model of others was related to less family and social loneliness, and these associations were mediated by greater perceived social support. Model of others also was associated with less romantic loneliness and model of self was associated with less loneliness in all domains, and these relations were partially mediated by perceived social support. Findings are discussed with respect to possible interventions to increase students' perceptions of available social support and to decrease overall loneliness levels.

Five-factor personality traits and subjective health among caregivers: The role of caregiver strain and self-efficacy.

This study examined the association among caregivers' five-factor personality traits and subjective health with particular emphasis on the role of two theoretically implicated mediators: multi-domain self-efficacy and caregiver strain. The sample comprised 536 informal caregivers (mean age = 62.9 years, SD = 19.9, 72% female, 98% White) of community-dwelling older adults with multiple functional impairments. Both physical health and mental health were negatively associated with neuroticism and positively associated with extraversion and conscientiousness. Agreeableness and openness were associated with better subjective mental health and physical health, respectively. Multiple mediation analyses indicated that self-efficacy mediated all observed associations between personality and subjective health, whereas caregiver strain selectively mediated the associations of neuroticism and agreeableness with mental health.

Loneliness, social interaction, and sex roles.

43 male and 53 female undergraduates maintained the Rochester Interaction Record for 2 wks, providing information about social interactions of 10 min or more. Ss then completed the revised UCLA Loneliness Scale and the Personal Attributes Questionnaire. For both sexes, loneliness was negatively related to the amount of time spent with females and to the meaningfulness of interaction with males and females. However, meaningfulness with males was more important than meaningfulness with females. Femininity was negatively related to loneliness for both sexes and partially mediated the above relationships. There were sex differences, however, in the extent to which variables overlapped in predicting loneliness. For example, a large group of nonlonely males was characterized both by having meaningful relationships with males and by spending time with females, whereas a 2nd group of nonlonely males was characterized simply by having meaningful relationships with males. The largest group of nonlonely females was characterized simply by having meaningful relationships with males, but another sizable group was characterized simply by spending time with females. Females doing both accounted for little of the variance. (26 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Age-related differences and change in positive and negative affect over 23 years.

Positive and negative affect, measured by the Bradburn Affect Balance Scale, were studied in a longitudinal sample spanning from 1971 to 1994. The sample (N?=?2,804) represented 4 generations of families. Linear trend analyses compared generations over time for positive and negative affect and also examined the possible influences of neuroticism and extraversion on initial levels of affect and patterns of change in affect. Negative affect decreased with age for all generations, although the rate was attenuated among the oldest adults. Higher neuroticism scores also attenuated the decrease in negative affect across time. For positive affect, the younger and middle-aged adults showed marked stability, but the older group evidenced a small decrease over time. Higher levels of extraversion were related to more stability in positive affect. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Longitudinal stability of personality traits: A multitrait–multimethod–multioccasion analysis.

The longitudinal stability of personality was investigated in a group of several hundred adults who were rated by themselves, their marriage partners, and their acquaintances in 1935-1938 and by themselves and their marriage partners in 1954-1955. For both men and women, there were very similar factorial structures in all five sources of ratings. Individual differences in neuroticism, social extraversion, and impulse control had reasonably high levels of longitudinal stability over a 19-year period. Both the synchronic and diachronic correlations converged across methods and discriminated among traits. Self-report personality inventory data available in 1935-1938 and 1954-1955 provided corroborating evidence of the longitudinal and methodological robustness of personality traits. In data gathered on the same panel in 1980-1981, the questionnaire and the life history correlates of neuroticism and social extraversion displayed patterns indicative of temporal stability, methodological convergence, and discrimination among constructs. The data of this longitudinal study carried out over five decades strongly indicate that there is a set of personality traits that are generalizable across methods of assessment and are stable throughout adulthood.
