Neuroticism and selective encoding and recall of symptoms: evidence from a combined concurrent-retrospective study.

The association between Neuroticism (N) and elevated symptom reporting has been attributed to differences in the encoding but not in the recall of illness episodes. If high-N persons are selective only at the encoding of illness information, then retrospective reports should be no more exaggerated than concurrent reports. This study uses a concurrent-retrospective design to examine selectivity in concurrent and retrospective reports of symptoms. Concurrent daily reports gathered over 2 months were only moderately correlated with retrospective symptom reports covering the same time period. The direct path from N to recalled symptoms was larger than the indirect path from N through concurrent to recalled symptoms for 3 out of 4 symptoms. Discussion concerns implications of using recollection-based measures, suggestions for reducing selective memory effects, and explanations regarding how and why N relates to selective information processing about the self.     

Within- and between individual variability of personality characteristics and physical exercise

Using two independent samples, the study investigated links of within- and between-individual variability in personality states in three personality domains—Neuroticism, Extraversion, and Conscientiousness—with physical activity. Activity was defined as self-reported quantity of exercising or walking/cycling. More physical activity was associated with people reporting higher levels of Extraversion and Conscientiousness than they usually did, with the associations clearly replicating across samples and generalizing to all items of these domains. This pattern tended to reflect associations at the level of between-individual differences. When the three domains simultaneously predicted activity, within-individual variance in Neuroticism also emerged as a positive predictor, whereas between-individual level associations waned. The findings are consistent with within-individual differences in personality ratings reflecting meaningful, context-relevant variability.     

Borderline but not antisocial personality disorder symptoms are related to self-reported partner aggression in late middle-age

We examined the relationship between personality pathology and the frequency of self-reported psychological and physical partner aggression in a community sample of 872 adults aged 55-64. Previous research suggests that antisocial and borderline personality disorder (PD) symptoms are associated with partner aggression. Controlling for gender, education, alcohol dependence, and other personality pathology, we found that borderline PD symptoms, which include abandonment fears, unstable identity, and affective instability, were significantly related to the frequency of self-reported aggression toward one's partner. This relationship was observed regardless of whether the participant's personality was described by a clinical interviewer, the participant themselves, or an informant chosen by the participant. Further, the relationship between borderline PD symptoms and self-reported partner aggression was moderated by gender such that women were driving the association. Conversely, antisocial PD symptoms, which include deceitfulness, irresponsibility, disregard for rules, and lack of remorse did not significantly account for variance in self-reported partner aggression.

Objective and subjective socioeconomic status and susceptibility to the common cold.

OBJECTIVE: We ask whether subjective socioeconomic status (SES) predicts who develops a common cold when exposed to a cold virus. DESIGN: 193 healthy men and women ages 21-55 years were assessed for subjective (perceived rank) and objective SES, cognitive, affective and social dispositions, and health practices. Subsequently, they were exposed by nasal drops to a rhinovirus or influenza virus and monitored in quarantine for objective signs of illness and self-reported symptoms. MAIN OUTCOME MEASURES: Infection, signs and symptoms of the common cold, and clinical illness (infection and significant objective signs of illness). RESULTS: Increased subjective SES was associated with decreased risk for developing a cold for both viruses. This association was independent of objective SES and of cognitive, affective and social disposition that might provide alternative spurious (third factor) explanations for the association. Poorer sleep among those with lesser subjective SES may partly mediate the association between subjective SES and colds. CONCLUSIONS: Increased Subjective SES is associated with less susceptibility to upper respiratory infection, and this association is independent of objective SES, suggesting the importance of perceived relative rank to health.     

How do i know what i feel? Evidence for the role of self‐categorisation in symptom perceptions

This paper extends the self‐categorisation model of symptom appraisals to predict that individuals who believe they have a given illness will perceive concurrent symptoms relevant to that illness to be more severe when they categorise themselves as members of a group of people with that illness. These predictions are supported with opportunity samples of individuals reporting, or not reporting a common cold (Study 1, N = 60) and reporting colds or tinnitus (Study 2, N = 64). In both studies, relevant symptoms were rated as more severe when illness group memberships were salient. The methodological, theoretical and clinical implications of these findings and possible therapeutic applications of self‐categorisation theory (SCT) to symptom perceptions are discussed.

Depression and Axis II symptomatology in an adolescent community sample: concurrent and longitudinal associations

The relationship between personality pathology and depression has been the focus of increasing attention, but few investigators have examined this issue prospectively or in adolescent community samples. The present study used both self report and interviewer assessments of personality disorder symptomatology and depression in a sample of 155 late adolescent women followed over three years. Personality pathology cluster and total scores demonstrated moderate to fairly high degrees of stability, indicating endurance of these traits in late adolescence. As predicted, Axis II symptoms were associated with concurrent depressive symptomatology. Overall, self-reported personality disorder symptoms, as well as those specifically in Clusters A and B, predicted interviewer-rated depression over two years beyond the contribution of initial depression, indicating that subclinical Axis II symptoms are a risk factor for subsequent depressive symptomatology.     

Personality Characteristics Associated with Persistent ADHD in Late Adolescence

This study focused on the personality characteristics associated with Attention-deficit/Hyperactivity disorder (ADHD) in a longitudinal sample of youth, with a particular focus on differences between those with and without persisting ADHD symptoms. Participants with ADHD (n = 90) were initially evaluated when they were 7–11 years old, and re-assessed at 16–22 years of age. Matched control subjects (n = 80) were recruited at the time of the follow-up evaluation. At follow-up, the Kiddie-SADS-PL, a semi-structured psychiatric interview, and the NEO-PI, a self-report personality inventory, were administered. Data were analyzed using multivariate analyses of variance (MANOVA). Results indicate that childhood ADHD is associated with lower scores on the NEO Conscientiousness subscale in adolescents/young adults—irrespective of the degree of ADHD persistence. In contrast, ratings of Neuroticism and Agreeableness appear to be more closely linked to adolescent status; those with persisting symptoms only exhibited increased Neuroticism and decreased Agreeableness. These results suggest that ADHD, and the degree to which symptoms persist into adolescence, may be closely linked to personality structure.     

Big five dimensions and ADHD symptoms: links between personality traits and clinical symptoms

Attention-deficit/hyperactivity disorder (ADHD) in adulthood is conceptualized as originating in childhood. Despite considerable theoretical interest, little is known about how ADHD symptoms relate to normal personality traits in adults. In 6 studies, the Big Five personality dimensions were related to ADHD symptoms that adults both recalled from childhood and reported concurrently (total N = 1,620). Substantial effects emerged that were replicated across samples. First, the ADHD symptom cluster of inattention-disorganization was substantially related to low Conscientiousness and, to a lesser extent, Neuroticism. Second, ADHD symptom clusters of hyperactivity-impulsivity and oppositional childhood and adult behaviors were associated with low Agreeableness. Results were replicated with self-reports and observer reports of personality in community and clinical samples. Findings support theoretical connections between personality traits and ADHD symptoms.     

Personality prototypes in eating disorders based on the Big Five model

A three factor model of personality pathology was investigated in a clinical sample of 335 female eating disordered patients. Cluster analysis of the Big Five NEO-FFI scales (Costa & McCrae, 1992) yielded three distinct personality profiles, which were consistent with previous studies: (1) a resilient/high functioning cluster with no clinical elevations on the NEO-FFI scales; (2) an undercontrolled/emotionally dysregulated cluster with elevated scores on the Neuroticism scale and low scores on Conscientiousness and Agreeableness; (3) an overcontrolled/constricted cluster showing high scores on Neuroticism and Conscientiousness and low scores on Openness to Experience. Comparing the three personality prototypes with respect to Axis I and Axis II disorders,resilients reported systematically less clinical and personality problems than both undercontrollers and overcontrollers. Compared to the latter, undercontrollers showed more impulsive personality features and behaviors. Finally, cluster membership was not clearly associated with eating disorder subtypes, suggesting that there is considerable variance in personality features and/or pathology within the various eating disorder categories.     

Personality and affectivity characteristics associated with eating disorders: a comparison of eating disordered, weight-preoccupied, and normal samples.

The purpose of this study was to assess the relative contribution of personality and emotional experience to self-reported eating attitudes in a group of patients with clinically diagnosed eating disorders, a weight-reduction training group (Weight Watchers), and a control group without body weight problems. Participants in this study (N = 114) completed Estonian versions of the Eating Disorder Inventory-2 (EDI-2; Garner, 1991), NEO Personality Inventory (Costa & McCrae, 1989), and Positive Affect and Negative Affect Schedule, Expanded Form (Watson & Clark, 1994). Data demonstrated validity of the Estonian version of EDI-2 in its ability to identify problems on a continuum of disordered eating behavior. Among the Big Five personality dimensions, Neuroticism made the largest contribution to EDI-2 subscales. Two other dimensions, Openness to Experience and Conscientiousness, also predispose individuals to eating problems. Personality traits made a larger contribution to the self-reported eating pathology than the self-rated effects experienced during the last few weeks. It was argued that personality dispositions have a larger relevancy in the etiology of eating disorders than emotional state.     

Social learning influences on menstrual symptoms and illness behavior

The contribution of learning to the adult experience of illness was investigated by asking 351 nursing students how their mothers reacted to menstrual symptoms and cold symptoms during their adolescence and how their mothers behaved when they themselves had menstrual symptoms. Mothers of respondents were independently asked the same questions. Nursing students who had been encouraged to adopt a sick role for menses or whose mothers modeled menstrual distress reported significantly more menstrual symptoms, clinic visits, and disability days for these symptoms as adults. Similarly, those encouraged to adopt a sick role for colds or who lived with a chronically ill person reported more clinic visits and disability days for nongynecological symptoms. Specific types of symptom reports and health care appeared to be learned: Encouragement and modeling of the menstrual sick role were more highly correlated with symptom reports, clinic visits, and absenteeism for menstrual than for nongynecological symptoms, and encouragement of the cold sick role was more highly correlated with nongynecological than with menstrual clinic visits and absenteeism.     

Audience Personality and the Selection of Media and Media Genres

The impact of personality characteristics (Extraversion, Neuroticism, Psychoticism) on audiences' use of movies, television, and radio, and on genre preferences within these media was explored. Extraversion was associated positively with in-home movie viewing and with listening to urban, jazz-classical, and pop-rock music. Neuroticism was associated positively with pop-rock music listening. Psychoticism was associated negatively with watching romance and comedy films, but this relation was moderated by an interaction in that the impact of Psychoticism was most powerful among those who were also high in Neuroticism. Follow-up analyses evaluating the impact of personality within groups defined by gender and race were also carried out. The results point to the potential of incorporating audiences' perceptions of the gratifications offered by particular media into further research. These perceptions, which are likely to vary across audience groups, may contribute to how personality factors are expressed in media behavior.     

Personality and coping in life challenge narratives

BackgroundSelf-reported personality traits are known to correlate with self-reported coping strategies. However, these correlations may be inflated by common method variance. The current study examined personality traits and coping strategies in autobiographical narratives.MethodIn open-ended interviews, 122 late-midlife participants described their single greatest life challenge. Participants’ responses were content coded for various coping strategies. We examined correlations between narrated coping strategies and self-reported personality traits assessed by the NEO-Five Factor Inventory.ResultsExtraversion was associated with narrated engagement coping. Neuroticism was associated with narrated disengagement coping. A trend suggested that conscientiousness was negatively associated with narrated disengagement coping. Surprisingly, openness was negatively associated with narrated problem-solving.ConclusionsThe current study replicates and extends the personality and coping literature into the domain of life narrative. Associations between extraversion, neuroticism, and coping styles appear to be robust outside the context of self-report coping questionnaires.     

Individual differences in susceptibility to infection and illness following respiratory virus challenge

Abstract

The aim of the present research was to investigate whether susceptibility to experimentally-induced respiratory virus infections and illness is related to measures of personality, physiological state, performance efficiency, and subjective ratings of alertness and motivation obtained prior to virus challenge. Two studies, using different viruses, showed that volunteers who subsequently developed colds had higher temperatures prior to virus challenge than those who remained free from illness. Similarly, those who later had colds were worse than other volunteers on certain performance tests given in the pre-challenge period. The results also showed that task-related motivation was related to subsequent infection. Personality scores were poor predictors of infection and illness, the only exception being introversion, which, in one study, was related to the likelihood of developing a sub-clinical infection.     

Relations between personality and coping: a meta-analysis

Personality may directly facilitate or constrain coping, but relations of personality to coping have been inconsistent across studies, suggesting a need for greater attention to methods and samples. This meta-analysis tested moderators of relations between Big Five personality traits and coping using 2,653 effect sizes drawn from 165 samples and 33,094 participants. Personality was weakly related to broad coping (e.g., Engagement or Disengagement), but all 5 traits predicted specific strategies. Extraversion and Conscientiousness predicted more problem-solving and cognitive restructuring, Neuroticism less. Neuroticism predicted problematic strategies like wishful thinking, withdrawal, and emotion-focused coping but, like Extraversion, also predicted support seeking. Personality more strongly predicted coping in young samples, stressed samples, and samples reporting dispositional rather than situation-specific coping. Daily versus retrospective coping reports and self-selected versus researcher-selected stressors also moderated relations between personality and coping. Cross-cultural differences were present, and ethnically diverse samples showed more protective effects of personality. Richer understanding of the role of personality in the coping process requires assessment of personality facets and specific coping strategies, use of laboratory and daily report studies, and multivariate analyses.     

Defensiveness and Symptom Reporting

This investigation examined whether high levels of defensiveness were associated with lower levels of reporting symptoms of ill health. Participants completed questionnaires measuring defensiveness, trait anxiety (neuroticism), and health. Analyses revealed that overall high defensiveness was significantly associated with lower levels of symptom reporting, and that among individuals high in neuroticism (a trait normally associated with high levels of symptom reporting), those individuals also high in defensiveness reported significantly lower levels of symptoms. The results suggest that defensiveness may act as a buffer against the perception and reporting of the symptoms of illness.

Positive and negative symptoms of schizotypy and the Five-factor model: a domain and facet level analysis

In this study, we investigated the Five-factor model in the concurrent prediction of positive symptom schizotypy as measured by the Magical Ideation (Eckblad & Chapman, 1983) and Perceptual Aberration (Chapman, Chapman, & Raulin, 1978) scales and negative symptom schizotypy as measured by the Physical Anhedonia (Chapman, Chapman, & Raulin, 1976) and Revised Social Anhedonia (Eckblad, Chapman, Chapman, & Mishlove, 1982; Mishlove & Chapman, 1985) scales. Previous studies suggest that these measures reflect the core symptoms found in schizotypal and schizoid personality disorder (Bailey, West, Widiger, & Freiman, 1993). Negative symptoms were significantly predicted by Neuroticism (+), Extraversion (-), Openness (-), and Agreeableness (-) domains of the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992). Additionally, positive symptoms were significantly predicted by Neuroticism (+), Openness (+), and Agreeableness (-). In addition, we examined the validity of lower order traits in de- scribing these symptoms of character pathology. These findings lend further support for the use of domain and facet scales of the NEO-PI-R in the identification of personality pathology.     

The relationship of personality to antisocial and neurotic behaviours as observed by teachers

Eight hundred and eight children in normal schools between the ages of 7 and 16 yr were rated on Rutter's Teachers' Rating Scale, and completed the EPQ giving Psychoticism (P), Extraversion (E), Neuroticism (N) and Lie (L). The children also reported on their own misbehaviour and social attitudes. Children exhibiting Antisocial behaviours were markedly high on P; also scoring low on L, and reporting non-conforming behaviour and attitudes. Children showing Neurotic behaviours did not have particularly distinctive personality scores, but were rather extraverted and conforming (high L). There was no relationship between Neuroticism as a disorder and Neuroticism as a personality trait. It is suggested that the P scale might usefully assist in the detection of antisocially disturbed children or in the selection of ‘high risk’ groups.     

Predictors Of Self-Reported Physical Symptoms in Low-Income, Inner-City African American Women: The Role of Optimism, Depressive Symptoms, and Chronic Illness

In this study we examined the association of optimism and depressive symptoms with self-reported physical symptoms in 241 low-income, inner-city African American women with or without a chronic illness (HIV). Although optimism was not a unique predictor of self-reported physical symptoms over and above depressive symptoms, optimism interacted with depressive symptoms and health status. In the community sample, but not the chronically ill sample, optimism buffered the association between depressive symptoms and self-reported physical symptoms. Clinical implications and directions for future research are discussed.
