Health complaints, stress, and distress: Exploring the central role of negative affectivity.

Most current models in health psychology assume that stress adversely affects physical health. We re-examined this assumption by reviewing extensive data from the literature and from six samples of our own, in which we collected measures of personality, health and fitness, stress, and current emotional functioning. Results indicate that self-report health measures reflect a pervasive mood disposition of negative affectivity (NA); self-report stress scales also contain a substantial NA component. However, although NA is correlated with health compliant scales, it is not strongly or consistently related to actual, long-term health status, and thus will act as a general nuisance factor in health research. Because self-report measures of stress and health both contain a significant NA component, correlations between such measures likely overestimate the true association between stress and health. Results demonstrate the importance of including different types of health measures in health psychology research.

The Psychological Meaning of Words: LIWC and Computerized Text Analysis Methods

We are in the midst of a technological revolution whereby, for the first time, researchers can link daily word use to a broad array of real-world behaviors. This article reviews several computerized text analysis methods and describes how Linguistic Inquiry and Word Count (LIWC) was created and validated. LIWC is a transparent text analysis program that counts words in psychologically meaningful categories. Empirical results using LIWC demonstrate its ability to detect meaning in a wide variety of experimental settings, including to show attentional focus, emotionality, social relationships, thinking styles, and individual differences.

Writing About Emotional Experiences as a Therapeutic Process

For the past decade, an increasing number of studies have demonstrated that when individuals write about emotional experiences, significant physical and mental health improvements follow The basic paradigm and findings are summarized along with some boundary conditions Although a reduction in inhibition may contribute to the disclosure phenomenon changes in basic cognitive and linguistic processes during writing predict better health Implications for theory and treatment are discussed

Forming a story: The health benefits of narrative

Writing about important personal experiences in an emotional way for as little as 15 minutes over the course of three days brings about improvements in mental and physical health. This finding has been replicated across age, gender, culture, social class, and personality type. Using a text-analysis computer program, it was discovered that those who benefit maximally from writing tend to use a high number of positive-emotion words, a moderate amount of negative-emotion words, and increase their use of cognitive words over the days of writing. These findings suggest that the formation of a narrative is critical and is an indicator of good mental and physical health. Ongoing studies suggest that writing serves the function of organizing complex emotional experiences. Implications for these findings for psychotherapy are briefly discussed.

Linguistic styles : Language use as an individual difference

Can language use reflect personality style? Studies examined the reliability, factor structure, and validity of written language using a word-based, computerized text analysis program. Daily diaries from 15 substance abuse inpatients, daily writing assignments from 35 students, and journal abstracts from 40 social psychologists demonstrated good internal consistency for over 36 language dimensions. Analyses of the best 15 language dimensions from essays by 838 students yielded 4 factors that replicated across written samples from another 381 students. Finally, linguistic profiles from writing samples were compared with Thematic Apperception Test coding, self-reports, and behavioral measures from 79 students and with self-reports of a 5-factor measure and health markers from more than 1,200 students. Despite modest effect sizes, the data suggest that linguistic style is an independent and meaningful way of exploring personality.

Stalking the perfect measure of implicit self-esteem: the blind men and the elephant revisited?

Recent interest in the implicit self-esteem construct has led to the creation and use of several new assessment tools whose psychometric properties have not been fully explored. In this article, the authors investigated the reliability and validity of seven implicit self-esteem measures. The different implicit measures did not correlate with each other, and they correlated only weakly with measures of explicit self-esteem. Only some of the implicit measures demonstrated good test-retest reliabilities, and overall, the implicit measures were limited in their ability to predict our criterion variables. Finally, there was some evidence that implicit self-esteem measures are sensitive to context. The implications of these findings for the future of implicit self-esteem research are discussed.

Lying Words: Predicting Deception from Linguistic Styles

Telling lies often requires creating a story about an experience or attitude that does not exist. As a result, false stories may be qualitatively different from true stories. The current project investigated the features of linguistic style that distinguish between true and false stories. In an analysis of five independent samples, a computer-based text analysis program correctly classified liars and truth-tellers at a rate of 67% when the topic was constant and a rate of 61% overall. Compared to truth-tellers, liars showed lower cognitive complexity, used fewer self-references and other-references, and used more negative emotion words.

Accelerating the Coping Process

On the basis of previous work, freshmen should evidence improved health after writing about their thoughts and feelings associated with entering college. One hundred thirty subjects were assigned to write either about coming to college or about superficial topics for 20 min on 3 days. One fourth of the subjects in each group wrote during the 1st, 5th, 9th, or 14th week of classes. Physician visits for illness in the months after writing were lower for the experimental than for the control subjects. Self-reports of homesickness and anxiety were higher in the experimental group 2-3 months after writing. By years end, experimental subjects were either superior or similar to control subjects in grade average and in positive moods. No effects emerged as a function of when people wrote, suggesting that the coping process can be accelerated. Implications for comparing insight treatments with catharsis and for distinguishing between objective and self-report indicators of distress are discussed.

Confession, Inhibition, and Disease

Publisher Summary This chapter explores the nature of confession and inhibition. Conversely, not confiding significant experiences is associated with increased disease rates, ruminations, and other difficulties. This pattern of findings has helped in developing a useful theory of active inhibition that shares many of the assumptions of learning theory, psychodynamic models, and more recent cognitive perspectives. The chapter examines the nature of confession per se. The chapter focuses on the physiological and psychological effects of confronting or actively avoiding past traumatic experiences. Based on a number of laboratory and field studies, it is clear that requiring people to write or talk about traumas is associated with both immediate and long-term health benefits. The chapter presents a formal theory of active inhibition. The links among the theory and Freud, animal learning, and cognitive perspectives are discussed in the chapter. The chapter describes the reexamination of catharsis, the development and breakdown of the self, and the role of psychosomatics in social psychology.

Who talks? The social psychology of illness support groups.

More Americans try to change their health behaviors through self-help than through all other forms of professionally designed programs. Mutual support groups, involving little or no cost to participants, have a powerful effect on mental and physical health, yet little is known about patterns of support group participation in health care. What kinds of illness experiences prompt patients to seek each others company? In an effort to observe social comparison processes with real-world relevance, support group participation was measured for 20 disease categories in 4 metropolitan areas (New York, Chicago, Los Angeles, and Dallas) and on 2 on-line forums. Support seeking was highest for diseases viewed as stigmatizing (e.g., AIDS, alcoholism, breast and prostate cancer) and was lowest for less embarrassing but equally devastating disorders, such as heart disease. The authors discuss implications for social comparison theory and its applications in health care.
