Construct validation of optimism and pessimism in older men: Findings from the normative aging study.

Validation of M. F. Scheier and C. S. Carver's (1985) Life Orientation Test has identified associations between bipolar optimism and several external constructs. However, optimism and pessimism may not be bipolar, but rather separate constructs. Furthermore, these constructs may be indistinguishable from personality traits, such as neuroticism and extraversion. This study examined the associations of separate optimism and pessimism measures with self-reports of hassles, psychological symptoms, and illness severity, controlling for personality. Ss were 1,192 men from the Normative Aging Study. Findings suggest that optimism and pessimism are separate and that their relations to external criteria remain, although attenuated, when neuroticism and extraversion are controlled.

Distinguishing optimism from pessimism in older adults: Is it more important to be optimistic or not to be pessimistic?

Confirmatory factor analysis revealed that the Life Orientation Test (LOT) consisted of separate Optimism and Pessimism factors among middle-aged and older adults. Although the two factors were significantly negatively correlated among individuals facing a profound life challenge (i.e., caregiving), they were only weakly correlated among noncaregivers. Caregivers also expressed less optimism than noncaregivers and showed a trend toward greater pessimism, suggesting that life stress may affect these dispositions. Pessimism, not optimism, uniquely predicted subsequent psychological and physical health; however, optimism and pessimism were equally predictive for stressed and nonstressed samples. By exploring optimism and pessimism separately, researchers may better determine whether the beneficial effects of optimism result from thinking optimistically, avoiding pessimistic thinking, or a combination of the two.

Mood, personality, and self-monitoring: Negative affect and emotionality in relation to frontal lobe mechanisms of error monitoring.

A fundamental question in frontal lobe function is how motivational and emotional parameters of behavior apply to executive processes. Recent advances in mood and personality research and the technology and methodology of brain research provide opportunities to address this question empirically. Using event-related-potentials (ERPs) to track error monitoring in real time, the authors demonstrated that variability in the amplitude of the error-related negativity (ERN) is dependent on mood and personality variables. College students who are high on negative affect (NA) and negative emotionality (NEM) displayed larger ERN amplitudes early in the experiment than participants who are low on these dimensions. As the high-NA and -NEM participants disengaged from the task, the amplitude of the ERN decreased. These results reveal that affective distress and associated behavioral patterns are closely related with frontal lobe executive functions.

Differential Associations of Dispositional Optimism and Pessimism With Coping, Goal Attainment, and Emotional Adjustment During Sport Competition.

This study examined the associations of dispositional optimism and pessimism with athletes' coping, goal attainment, and affective states during a sport competition. Results of path analyses showed that dispositional optimism and pessimism correlated differently with coping and affective variables. Mediating analyses indicated that task-oriented coping partially mediated the relationship of optimism with postcompetition positive affective state, whereas disengagement-oriented coping fully mediated the relationship of pessimism with postcompetition anger/dejection. Ancillary hierarchical regressions also indicated that distraction-oriented coping may lead to positive outcomes when used in concordance with task-oriented coping. Overall, these results lent credence to the utility of a bidimensional model of optimism and pessimism. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

From optimism and pessimism to coping: The mediating role of academic motivation.

The main goal of this study was to examine an integrative model in which academic motivation was hypothesized to mediate the relationships between dispositional optimism and pessimism and coping utilization during the preparation for midterm exams. A sample of 299 undergraduate students completed measures of optimism and academic motivation two weeks prior to midterm exams and measures of academic motivation and coping two weeks after midterm exams. Results of structural equation modeling indicated that self-determined motivation mediated the relationship between dispositional optimism and task-oriented coping, whereas non-self-determined motivation mediated the relationship between dispositional pessimism and disengagement-oriented coping. Furthermore, task-oriented coping was associated with an increase in self-determined motivation from Time 1 to Time 2, whereas disengagement-oriented coping related to an increase in non-self-determined motivation.

"Effects of optimism, pessimism, and trait anxiety on ambulatory blood pressure and mood during everyday life": Correction to R?ikk?nen et al. (1999).

Reports an error in the original article by K. R?ikk?nen et al (Journal of Personality and Social Psychology, 1999, 76(1), 104–113). Table 4 on page 111 contained an error. The 4 sets of column heads ("Adjusted" and "Unadjusted") were inadvertently transposed. The corrected table is provided. (The following abstract of this article originally appeared in record 1999-00166-008): This study tested whether dispositional measures of optimism, pessimism, and anxiety affected ambulatory blood pressure (BP) and mood and whether any cardiovascular effects of dispositions were moderated by mood. Pessimistic and anxious adults had higher BP levels and felt more negative and less positive than did optimists or low anxious adults throughout the monitoring. The few times that optimists did feel negative were associated with levels of BP as high as those observed among pessimists or anxious individuals, regardless of their mood. To the extent that trait anxiety measures neuroticism, these findings suggest that neuroticism is directly related to health indicators rather than simply to illness behavior. Furthermore, the results suggest that pessimism has broad physiological and psychological consequences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Optimism, pessimism, and positive and negative affectivity in middle-aged adults: A test of a cognitive-affective model of psychological adjustment.

This study attempted to address limitations in the understanding of optimism and pessimism among middle-aged adults. Specifically, a model of affectivity as a mediator of the link between outcome expectancies and psychological adjustment (life satisfaction and depressive symptoms) was presented and examined in a sample of 237 middle-aged adults. Consistent with a mediation model, results of path analyses indicated that optimism and pessimism (particularly the former) had significant direct and indirect links (by means of positive and negative affectivity) with depressive symptoms and life satisfaction. These results add to the small but growing literature identifying optimism and pessimism as important concomitants of psychological adjustment in more mature adults.

Mood management and nicotine gum in smoking treatment: a therapeutic contact and placebo-controlled study

Earlier research indicated that a 10-session mood management (MM) intervention was more effective than a 5-session standard intervention for smokers with a history of major depressive disorder (MDD). In a 2 x 2 factorial design, the present study compared MM intervention to a contact-equivalent health education intervention (HE) and 2 mg to 0 mg of nicotine gum for smokers with a history of MDD. Participants were 201 smokers, 22% with a history of MDD. Contrary to the earlier findings, the MM and HE interventions produced similar abstinence rates: 2 mg gum was no more effective than placebo. History-positive participants had a greater increase in mood disturbance after the quit attempt. Independent of depression diagnosis, increases in negative mood immediately after quitting predicted smoking. No treatment differences were found in trends over time for measures of mood, withdrawal symptoms, pleasant activities and events, self-efficacy, and optimism and pessimism. History-positive smokers may be best treated by interventions providing additional support and contact, independent of therapeutic content.     

Affect, personality, and social activity.

Examined relations between social activity and state and trait measures of Positive and Negative Affect. In Study 1, Ss completed scales relevant to 3-factor models of personality and a weekly mood and social activity questionnaire for 13 wks. In Study 2, Ss completed measures of the 5-factor model of personality and a daily mood and social activity survey for 6–7 wks. In within- and between-Ss analyses, socializing correlated significantly with state measures of Positive Affect and with trait measures of Extraversion/Positive Emotionality. These relations were relatively general across various types of positive affect and social events; however, specific types of social events also were differentially related to affect. In contrast, social activity had no consistent association with measures of Negative Affect or the other personality dimensions. The results support a temperamental view of Extraversion.

A Double Dissociation Between Mood States and Personality Traits in the Anterior Cingulate.

Neuroticism and extraversion are personality traits associated with negative and positive mood states, respectively, confounding trait and state factors that may affect brain responses to emotional stimuli. The authors dissociated these factors using fMRI and the emotional Stroop attention task: Anterior cingulate (AC) response to positive stimuli varied as a function of personality trait, but not mood state, whereas AC response to negative stimuli varied as a function of mood state, but not personality trait. Negative mood, but not personality trait, also increased the functional connectivity between AC and other regions. Variance in AC activation can thus be ascribed to an intersubject variable (extraversion) when responding to positive stimuli and an intrasubject variable (mood) when responding to negative stimuli. The former may explain stable differences between extraverts and introverts. The latter may provide an adaptive mechanism to expand an individual's dynamic range in response to potentially dangerous or threatening stimuli.

Personality differentiation, effectiveness of personality integration, and mood in female college students.

Personality differentiation was measured by an index computed from 72 female undergraduates' rod-and-frame test and Embedded Figures Test scores. Effectiveness of personality integration was measured by the Ego Identity Incomplete Sentences Blank. Personal Feelings scales were used as the mood assessment instrument. The final sample of 31 Ss rated their moods 3 times daily on each of the 16 Personal Feelings scales for 33 consecutive days. Measures of 3 characteristics of mood—affective complexity, mood level, and mood variability—were constructed by factor analysis of mood-rating records. Psychological differentiation theory was used to generate hypotheses concerning mood/personality relationships. Results indicate that (a) greater personality differentiation was associated with less affective complexity; (b) neither personality differentiation nor effectiveness of personality integration was significantly associated with mood level; and (c) greater effectiveness of personality integration was associated with less mood variability.

Second gene expression in bicistronic constructs using short synthetic intercistrons and viral IRES sequences

The authors addressed 5 issues bearing on the validity of the construct of depressive personality disorder (DPD): its relationship with the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1987) mood and personality disorders and normal personality dimensions of negative and positive affectivity, its stability over 30-months, and its impact on the course of Axis I depressive disorders. Two samples were used: 156 outpatients with mood disorders, personality disorders, or both, and 267 of their 1st-degree relatives. The association between DPD and dysthymia was fairly modest, whereas the associations with major depression and the personality disorders were quite low. DPD was moderately correlated with both negative and positive affectivity; however, it contributed unique information beyond that available from the 2 emotional superfactors. Finally, DPD was moderately stable over a 30-month period and was associated with a poorer course of depression.     

Optimism and Pessimism as Mediators of the Relations Between Self-Discrepancies and Distress Among Asian and European Americans.

The authors examined the role of undesired self-discrepancies in predicting emotional distress among Asian and European Americans, whether undesired self-discrepancies are stronger predictors of distress for Asian than for European Americans, and whether optimism and pessimism mediate the relations between ideal, ought, and undesired self-discrepancies and emotional distress. Self-identified Asian/Asian American (n = 140) and European American (n = 189) college students completed measures of self-discrepancies, optimism/pessimism, social anxiety, and depressive symptoms. Results show that for both Asian Americans and European Americans, greater similarity to the undesired self is equally predictive of symptoms of depression, whereas distance from the undesired self is more predictive of social anxiety for Asian Americans than for European Americans. Furthermore, pessimism fully mediates the relations between undesired self-discrepancies and depressive symptoms for both Asian Americans and European Americans, although pessimism was a stronger predictor of depression for European Americans than for Asians/Asian Americans.

Optimism and Pessimism as Predictors of Change in Health After Death or Onset of Severe Illness in Family.

The authors prospectively examined changes in health after a major life event (death or onset of severe illness in family) among 5,007 employees (mean age=44.8 years) whose optimism and pessimism levels were assessed in 1997 and major life events in 2000. Health was indicated by sickness absence days during a period covering 36 months prior to the event and 18 months after the event. Increase in sick days after the event was smaller and returned to the preevent level more quickly among highly optimistic individuals than among their counterparts with low optimism. Parallel changes were not observed in relation to pessimism. These findings suggest that optimism may reduce the risk of health problems and may be related to a faster recovery after a major life event.

Optimism is associated with mood, coping, and immune change in response to stress.

This study explored prospectively the effects of dispositional and situational optimism on mood (N=90) and immune changes (N=50) among law students in their first semester of study. Optimism was associated with better mood, higher numbers of helper T cells, and higher natural killer cell cytotoxicity. Avoidance coping partially accounted for the relationship between optimism and mood. Among the immune parameters, mood partially accounted for the optimism-helper T cell relationship, and perceived stress partially accounted for the optimism-cytotoxicity relationship. Individual differences in expectancies, appraisals, and mood may be important in understanding psychological and immune responses to stress.

Perceived likelihood as a measure of optimism and pessimism: Support for the Future Events Scale.

The Future Events Scale (FES; S. M. Andersen, 1990) is an expectancy-based measure of optimism and pessimism, grounded in cognitive theories of depression, with implications for clinical practice. Although ample research has documented the utility of the FES in predicting important cognitive and behavioral outcomes, psychometric data on the scale are lacking. The current article presents multisample analyses to show that the FES has clear factor structure, good reliability, and a theoretically meaningful nomological network. The FES is shown to be distinct from the best known measure of optimism and pessimism, the Life Orientation Test (M. F. Scheier & C. S. Carver, 1985). Applications are discussed.

Structural convergence of mood and personality: Evidence for old and new directions.

Using factor analytic techniques, extensively researched 2-dimensional models of mood structure (D. Watson and A. Tellegen; see record 1986-00110-001) and personality structure (H. J. and M. W. Eysenck, 1985) were examined for their degree of convergence. As hypothesized, it was shown that extraversion and positive affect share a common dimension in combined mood–personality space and that neuroticism and negative affect together define the 2nd dimension of this space. Significantly, this finding held whether mood was assessed as a state or a trait. The circumplex structure of trait and state mood was also assessed, providing strong support for most octants of the Watson and Tellegen model. Finally, scales of state mood, trait mood, and personality were assessed and differentiated according to theoretical expectations. Implications for research based on a unified map of the 2-dimensional personality–mood space were elucidated. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of stressful daily events on mood states: relationship to global perceived stress

This study used experience sampling methodology to examine the relationship between stressful daily events and mood. Eighty-five male white-collar workers completed self-reports 10 times a day for 5 days. Controlling for individual differences in mood levels, multilevel regression analyses showed that events were followed by increases in negative affect (NA) and agitation (Ag) and by decreases in positive affect (PA). More unpleasant events were associated with greater changes in all three mood dimensions; controllability mitigated the effects of events on NA and PA. Prior events had persistent effects on current mood. High perceived stress (PS) was associated with greater reactivity of NA and PA to current events, whereas trait anxiety moderated reactivity of Ag. Results indicate that PS is related not only to a higher frequency of reported events but also to more intense and prolonged mood responses to daily stress.
