Optimism versus pessimism predicts the quality of women's adjustment to early stage breast cancer.

BACKGROUND: Recent studies indicate that breast cancer patients do not usually experience the devastating psychological consequences once viewed as inevitable. However, some adjust to the disease more poorly than others. This study examined the personality trait of optimism versus pessimism as a predictor of adjustment over the first year, postsurgery. METHODS: Seventy women with early stage breast cancer reported on their general optimism-pessimism at diagnosis. One day before surgery, and at 3-month, 6-month, and 12-month follow-ups, they reported their subjective well-being (mood scales and a measure of satisfaction with life). At follow-ups, they also rated their sex lives, indicated how much physical discomfort was interfering with their daily activities, and reported on thought intrusion. RESULTS: Pessimism displayed poorer adjustment at each time point by all measures except interference from pain. Even controlling for previous well-being, pessimism predicted poorer subsequent well-being, suggesting that pessimism represents a vulnerability to a negative change in adjustment. In contrast, effects of pessimism on quality of sex life and thought intrusion were not incremental over time. Additional analyses indicated that effects of the optimism-pessimism measure were captured relatively well by a single item from the scale. CONCLUSIONS: A sense of pessimism about one's life enhances a woman's risk for adverse psychological reactions to the diagnosis of, and treatment for, breast cancer. This finding suggests the potential desirability of assessing this quality informally in patients, to serve as a warning sign regarding the patient's well-being during the period surrounding and following surgery.

Situational coping and coping dispositions in a stressful transaction.

After reporting dispositional coping styles, students reported situational coping and 4 classes of affect (from threat, challenge, harm, and benefit appraisals) 2 days before an exam, after the exam but before grades were posted, and after posting of grades. Coping did not predict lower levels of future distress; indeed, some coping seemed to induce feelings of threat. Feelings of harm before the exam induced several kinds of coping after the exam, mostly dysfunctional. Confidence about one's grade was a better predictor of emotions throughout than was coping. Dispositional coping predicted comparable situational coping at low-moderate levels in most cases. Coping dispositions did not reliably predict emotions, however, with these exceptions: Dispositional denial was related to threat, as was dispositional use of social support; dispositional use of alcohol was related to both threat and harm.

Distinguishing optimism from neuroticism (and trait anxiety, self-mastery, and self-esteem): a reevaluation of the Life Orientation Test.

Research on dispositional optimism as assessed by the Life Orientation Test (Scheier & Carver, 1985) has been challenged on the grounds that effects attributed to optimism are indistinguishable from those of unmeasured third variables, most notably, neuroticism. Data from 4,309 subjects show that associations between optimism and both depression and aspects of coping remain significant even when the effects of neuroticism, as well as the effects of trait anxiety, self-mastery, and self-esteem, are statistically controlled. Thus, the Life Orientation Test does appear to possess adequate predictive and discriminant validity. Examination of the scale on somewhat different grounds, however, does suggest that future applications can benefit from its revision. Thus, we also describe a minor modification to the Life Orientation Test, along with data bearing on the revised scale's psychometric properties.

How coping mediates the effect of optimism on distress: a study of women with early stage breast cancer.

At diagnosis, 59 breast cancer patients reported on their overall optimism about life; 1 day presurgery, 10 days postsurgery, and at 3-, 6-, and 12-month follow-ups, they reported their recent coping responses and distress levels. Optimism related inversely to distress at each point, even controlling for prior distress. Acceptance, positive reframing, and use of religion were the most common coping reactions; denial and behavioral disengagement were the least common reactions. Acceptance and the use of humor prospectively predicted lower distress; denial and disengagement predicted more distress. Path analyses suggested that several coping reactions played mediating roles in the effect of optimism on distress. Discussion centers on the role of various coping reactions in the process of adjustment, the mechanisms by which dispositional optimism versus pessimism appears to operate, third variable issues, and applied implications.

Effects of mastectomy versus lumpectomy on emotional adjustment to breast cancer: a prospective study of the first year postsurgery.

PURPOSE: Procedure (mastectomy v lumpectomy) and choice of procedure were examined as predictors of adjustment to breast cancer in a prospective study of the experiences of the first year after surgery. PATIENTS AND METHODS: Breast cancer patients were interviewed the day before surgery, 10 days after surgery, and at the 3-month, 6-month, and 12-month follow-ups. Patients included 24 women who received mastectomy on strong recommendation, 24 who chose mastectomy for other reasons, and 15 who chose lumpectomy. Subjective well-being was assessed in terms of mood disturbance, perceived quality of life, life satisfaction, marital satisfaction, perceptions of social support, and self-rated adjustment. RESULTS: Surgical groups differed in well-being in only one respect: lumpectomy patients reported a higher-quality sex life at 6 and 12 months postsurgery than mastectomy patients. Choice of surgical procedure predicted higher levels of life satisfaction at 3 months. CONCLUSION: The lack of difference between surgical groups in areas other than sexual adjustment replicates previous findings, but extends them by (1) using a fully prospective design, (2) providing data on the period surrounding the surgery (as well as later periods), and (3) examining a broader range of indices of well-being than usual.

Abstinence expectancy and abstinence among men undergoing inpatient treatment for alcoholism.

Several personal and situational variables were examined as possible predictors of renewed drinking before completion of an inpatient alcoholism treatment program: either drinking surreptitiously while remaining in the program or leaving the program to return to alcohol. Male alcoholics were interviewed shortly after entering the program and again as they finished treatment. The first interview assessed predictor variables, the second interview assessed drinking during treatment. Treatment dropouts were pursued to determine their drinking status. Discriminant analyses revealed that renewed drinking was inversely related to subjects' reported expectancies of remaining abstinent during the next 6 months, positively related to employment instability, and also related to racial group. Analysis of premature termination of treatment as an alternative outcome variable suggested that these effects were specific to renewed drinking per se. Discussion centers on the potential relevance of expectancy-based theories of self-regulation to behavior during the period of treatment.

Assessing coping strategies: a theoretically based approach.

We developed a multidimensional coping inventory to assess the different ways in which people respond to stress. Five scales (of four items each) measure conceptually distinct aspects of problem-focused coping (active coping, planning, suppression of competing activities, restraint coping, seeking of instrumental social support); five scales measure aspects of what might be viewed as emotional-focused coping (seeking of emotional social support, positive reinterpretation, acceptance, denial, turning to religion); and three scales measure coping responses that arguably are less useful (focus on and venting of emotions, behavioral disengagement, mental disengagement). Study 1 reports the development of scale items. Study 2 reports correlations between the various coping scales and several theoretically relevant personality measures in an effort to provide preliminary information about the inventory's convergent and discriminant validity. Study 3 uses the inventory to assess coping responses among a group of undergraduates who were attempting to cope with a specific stressful episode. This study also allowed an initial examination of associations between dispositional and situational coping tendencies.

How should multifaceted personality constructs be tested? Issues illustrated by self-monitoring, attributional style, and hardiness.

Two or more dimensions unintentionally varied simultaneously are said to be confounded, but several theories in personality intentionally combine 3 or more distinct qualities. Researchers using these theories sum the qualities before testing predictions. How wise is this practice? The practice appears to derive from 2 distinct lines of reasoning. One of them assumes that the component dimensions converge on a single underlying quality (latent variable) that each reflects imperfectly. The other assumes a synergy among dimensions. Issues arising from each line of reasoning are illustrated by examining self-monitoring, attributional style, and hardiness. Conclusions are that (a) information is lost whenever a latent variable theory is tested solely by a composite and (b) a synergistic theory can be tested only through a statistical interaction.

Dispositional optimism and recovery from coronary artery bypass surgery: the beneficial effects on physical and psychological well-being.

The effect of dispositional optimism on recovery from coronary artery bypass surgery was examined in a group of 51 middle-aged men. Patients provided information at three points in time--(a) on the day before surgery, (b) 6-8 days postoperatively, and (c) 6 months postoperatively. Information was obtained relating to the patient's rate of physical recovery, mood, and postsurgical quality of life. Information was also gathered regarding the manner in which the patients attempted to cope with the stress of the surgery and its aftermath. As expected, dispositional optimism proved to be an important predictor of coping efforts and of surgical outcomes. More specifically, dispositional optimism (as assessed prior to surgery) correlated positively with manifestations of problem-focused coping and negatively with the use of denial. Dispositional optimism was also associated with a faster rate of physical recovery during the period of hospitalization and with a faster rate of return to normal life activities subsequent to discharge. Finally, there was a strong positive association between level of optimism and postsurgical quality of life at 6 months.

Associations of blood pressure with self-report measures of anger and hostility among black and white men and women.

This study examined associations between blood pressure (BP) and dispositional variables pertaining to anger and hostility. Black and White 25- to 44-year old male and female normotensives and unmedicated mild to moderate hypertensives completed four reliable self-report scales--the Cook-Medley Hostility (Ho) Scale, the Trait Anger subscale of the State-Trait Anger Scale (STAS-T), and the Cognitive Anger and Somatic Anger subscales of the Cognitive-Somatic Anger Scale--plus the Framingham Anger Scale and the Harburg Anger Scale. They also engaged in three laboratory tasks--Type A Structured Interview (SI), a video game, and a cold pressor task--that elicit cardiovascular reactivity. Ambulatory BP readings at home and at work were also obtained from most subjects. Blacks had significantly higher Ho and lower STAS-T scores than did Whites. Women reported higher levels of somatic anger than did men. White women showed significant positive correlations between STAS-T and systolic BP (SBP) and diastolic BP (DBP) both at rest in the laboratory and during the SI. Black women revealed significant positive relationships between STAS-T and SBP and DBP at rest in the laboratory and at work as well as with DBP during the cold pressor test. For Black men, cognitive anger and DBP at rest were positively related. In contrast, White men revealed significant negative correlations between Ho scores and SBP at rest and during the video game; these men also showed significant negative relationships between somatic anger and SBP and DBP reactivity during the cold pressor test. Women, but not men, showed significant positive relationships between all four anger measures and ambulatory BP at work. Whereas main effects relating anger and cardiovascular measures were not apparent as a function of race, Blacks demonstrated significantly greater SBP and DBP reactivity than Whites during the cold pressor test, with the converse occurring during the SI. Men demonstrated significantly greater DBP reactivity than women during the video game. The present findings indicate that self-reports on anger/hostility measures and cardiovascular responses to behavioral tasks differ as a function of race but that relationships between anger and BP regulation need to take into account possible race-sex interactions and selection of anger/hostility measures.

Predicting successful completion of an aftercare program following treatment for alcoholism: the role of dispositional optimism.

In this study we investigated several variables as potential predictors of success in completing a transition program after treatment for alcoholism. Subjects were 54 men who had completed a 30-day treatment program and who were subsequently admitted to a 90-day inpatient aftercare program. The outcome measure was successful completion of this latter program. Predictor variables were dispositional optimism, hassles, uplifts, and several demographic variables. Optimism was positively associated with successful outcome. The simple association between uplifts and outcome also approached significance, but in the opposite to expected direction. Discriminant analyses used both of these variables, as well as age and education level, as predictors of successful outcome. There was no evidence of a role for hassles. Discussion centers on the importance of dispositional optimism as a predictor of successful adaptation in a variety of behavioral domains.

Dispositional optimism and physical well-being: the influence of generalized outcome expectancies on health.

This article explores the implications that dispositional optimism holds for physical well-being. Research is reviewed that links optimism to a number of different positive health-relevant outcomes, ranging from the development of physical symptoms to recovery from coronary artery bypass surgery. Additional findings are described which suggest that these beneficial effects are partly due to differences between optimists and pessimists in the strategies that they use to cope with stress. A number of other potential mediators are also discussed, including some that are physiologic in nature. The article closes with a discussion of the relationships between our own theoretical account of the effects of optimism and several other conceptual approaches.

Coping with stress: divergent strategies of optimists and pessimists.

Previous research has shown that dispositional optimism is a prospective predictor of successful adaptation to stressful encounters. In this research we attempted to identify possible mechanisms underlying these effects by examining how optimists differ from pessimists in the kinds of coping strategies that they use. The results of two separate studies revealed modest but reliable positive correlations between optimism and problem-focused coping, seeking of social support, and emphasizing positive aspects of the stressful situation. Pessimism was associated with denial and distancing (Study 1), with focusing on stressful feelings, and with disengagement from the goal with which the stressor was interfering (Study 2). Study 1 also found a positive association between optimism and acceptance/resignation, but only when the event was construed as uncontrollable. Discussion centers on the implications of these findings for understanding the meaning of people's coping efforts in stressful circumstances.

Concordance between clinicians' and patients' ratings of anxiety and depression as mediated by private self-consciousness.

This study assesses the relations between the ratings of clinicians and psychiatric inpatients on several anxiety and depression measures, as mediated by private self-consciousness. The overall concordance between clinicians' and patients' ratings is quite high, particularly on the depression measures. Levels of private self-consciousness do not appear to mediate concordance of structured behavior or symptom-based ratings of either anxiety or depression; however, there is limited support for levels of private self-consciousness mediating concordance between patients' global ratings of anxiety and clinicians' anxiety ratings.

Depression and cognitive style: comparisons between measures.

Several instruments have been developed recently to measure cognitive styles associated with depression. At least four of them appear to have an underlying similarity. Each appears to reflect a tendency for respondents to infer a general lack of self-worth (or a continued likelihood of bad events) on the basis of a single discrete failure. The present research was a comparative test of one of these scales against the other three in terms of associations with Beck Depression Inventory (BDI) scores. Though all instruments were significantly correlated with BDI, partial correlations revealed that our generalization scale was a more robust predictor of BDI than were (a) a measure of characterological self-blame, (b) a measure of cognitive bias, and (c) a measure of attributional style.

Optimism, coping, and health: assessment and implications of generalized outcome expectancies.

This article describes a scale measuring dispositional optimism, defined in terms of generalized outcome expectancies. Two preliminary studies assessed the scale's psychometric properties and its relationships with several other instruments. The scale was then used in a longitudinal study of symptom reporting among a group of undergraduates. Specifically, respondents were asked to complete three questionnaires 4 weeks before the end of a semester. Included in the questionnaire battery was the measure of optimism, a measure of private self-consciousness, and a 39-item physical symptom checklist. Subjects completed the same set of questionnaires again on the last day of class. Consistent with predictions, subjects who initially reported being highly optimistic were subsequently less likely to report being bothered by symptoms (even after correcting for initial symptom-report levels) than were subjects who initially reported being less optimistic. This effect tended to be stronger among persons high in private self-consciousness than among those lower in private self-consciousness. Discussion centers on other health related applications of the optimism scale, and the relationships between our theoretical orientation and several related theories.

Cognitive characteristics of the type A coronary-prone behavior pattern.

Recent findings indicate that Type As attend more to tasks defined as central, and less to tasks defined as peripheral, than do Type Bs. If this A-B difference in allocation of attention occurs naturally, as well as in response to experimental instructions, it would have implications for other phenomena, such as the process of creating a category from a series of perceptual events. It was reasoned that across a series of acquisition stimuli, Type As, compared to Type Bs, would be more responsive to the development of central tendencies in the frequency of appearance of the attributes that comprise the stimuli. That is, Type As should be more attentive to frequently occurring attributes (by virtue of their centrality in the evolving category definition) and less attentive to rarely occurring attributes. This difference in attention should lead to a difference in encoding. On a subsequent recognition-memory task, then, Type As should report with greater certainty than Type Bs that they had seen stimuli composed of frequently observed attributes and should report with greater certainty that they had not seen stimuli composed of rarely observed attributes. In a test of this reasoning, students classified as As and Bs completed a concept-formation and recognition-memory task under one of four levels of situational challenge. The predicted patterns occurred among subjects in whom moderate and high levels of challenge had been induced. The findings thus support the arguments that As and Bs process information differently and that this processing difference must be elicited by situational challenge.
