Association between the Five Factor personality traits and perceived stress: is the effect mediated by general self-efficacy?

Abstract

Ill-health resulting from chronic stress is influenced by personality traits leading to different ways of appraising and coping with life's daily hassles. Using a large population sample the study aimed to investigate possible associations between perceived stress and the personality dimensions of neuroticism, extroversion, openness, agreeableness, and conscientiousness, and to explore the role of general self-efficacy (GSE). A population-based cross-sectional study was conducted at the Research Centre for Prevention and Health, Denmark, in 2006–2008. Men and women (N=3471) aged 18–69, were randomly sampled in the suburbs of Copenhagen. We used the NEO Five-Factor Inventory (NEO-FFI), Cohen's Perceived Stress Scale and the General Self-Efficacy Scale. Negative associations were found between perceived stress and extroversion, conscientiousness, agreeableness, and openness – the latter initially non-significant – whilst neuroticism had a positive association. The associations with agreeableness and openness became positive and significant, respectively, when GSE was included. All five personality-stress models were mediated by GSE, with extroversion and conscientiousness having the strongest mediating effect. The strongest stress-association was found for neuroticism. GSE was shown to change the impact and interpretation of the personality dimensions on perceived stress. These results indicate that GSE is an important factor to consider in the link between personality and perceived stress.     

Processing lexical ambiguity and visual word recognition in a deep orthography

We investigated the effect of semantic and phonemic ambiguity on lexical decision and naming performance in the deep Hebrew orthography. Experiment 1 revealed that lexical decisions for ambiguous consonant strings are faster than those for any of the high- or low-frequency voweled alternative meanings of the same strings. These results suggested that lexical decisions for phonemically and semantically ambiguous Hebrew consonant strings are based on the ambiguous orthographic information. However, a significant frequency effect for both ambiguous and unambiguous words suggested that if vowels are present, subjects do not ignore them completely while making lexical decisions. Experiment 2 revealed that naming low-frequency voweled alternatives of ambiguous strings took significantly longer than naming the high-frequency alternatives or the unvoweled strings without a significant difference between the latter two string types. Voweled and unvoweled unambiguous strings, however, were named equally fast. We propose that semantic and phonological disambiguation of unvoweled words in Hebrew is achieved in parallel to the lexical decision, but is not required by it. Naming Hebrew words usually requires a readout of phonemic information from the lexicon.     

A developmentally keyed scheme for the placement of gay men into psychotherapy groups

Patients can meet their needs for intimacy and individuation within the context of long-term psychotherapy groups. This is especially true for gay male patients as they work toward the development of a positive gay identity. Coming out is a social phenomenon, which is why groups are especially suited to the tasks involved. Historically, mixed groups of gay and nongay men and women have not been a safe or neutral treatment atmosphere for gay men due to therapists' prejudicial assumptions and a lack of understanding of gay male development. A developmental scheme will be presented which is keyed to the particular needs of gay men depending on their developmental stage of functioning. This scheme should serve as a more rational and appropriate guide for the diagnosis, treatment planning, and assigning of gay men to long-term psychotherapy groups.     

Race Relations on Prime Time Television Reconsidered: Patterns of Continuity and Change

This study was designed to assess the changes that have occurred in the portrayals of black people and cross-racial relationships in prime-time television broadcasting during the past decade. By replicating the content analysis procedures used by Weigel, Loomis, and Soja (1980), this investigation provided a consistent basis for comparing two similar samples of television content drawn, respectively, from 1978 and 1989. Results of this comparison indicated that, although black appearances and cross-racial interactions were no more frequent in the 1989 sample of product commercials, the black presence in prime-time programming had increased substantially. As compared to 1978, the proportion of time that one or more black characters were on the screen more than doubled, while the frequency of cross-racial interactions more than tripled in the 1989 sample. Nevertheless, ratings of qualitative dimensions of these cross-racial interactions suggested that relationships between blacks and whites on television continued to be portrayed as cooperative but emotionally detached, particularly when the relationships occurred outside of the work place.     

Depression,restraint and eating behavior

Contrary to the belief that weight loss is a principal symptom of depression, several recent studies have suggested that certain people gain rather than lose weight when depressed. The present experiment concerned the effects of experimentally induced mood states on the eating behavior of high- and low-restraint persons. Sixty-eight female undergraduates were randomly assigned to one of three groups each designed to induce a different mood state (depressed, neutral or elated), and were classified as high or low restraint based on their responses to a questionnaire. During the mood induction procedure subjects were provided with the opportunity to eat. High-restraint persons induced into a depressed mood ate significantly more than high-restraint persons induced into neutral or elated moods, and more than low-restraint persons induced into a depressed mood. This effect was most prominent among subjects who scored high on the weight-fluctuation factor of the restraint scale. There was no evidence that this effect occurred among subjects who scored high on the concern for dieting factor. The role of emotional arousal on the self-control over eating behavior of high weight-fluctuation persons, and the implications of these findings for the evaluation of depression were discussed.     

Effects of instructions and biofeedback on EEG-alpha production and the effects of EEG-alpha biofeedback training for controlling arousal in a subsequent stressful situation

In Phase One, 44 subjects participated in a 2 (instructions to increase alpha, no instructions to increase alpha) × 2 (alpha biofeedback, no alpha biofeedback) factorial experiment. Results indicated that increases in alpha production were due to instructions to increase alpha and that biofeedback had no effect on alpha production. In Phase Two, the 44 subjects from Phase One were exposed to a threat of shock whereas 11 additional subjects in a control condition were not. The design employed in Phase Two was a 2 (previous instructions and stress, no previous instructions and stress) × 2 (previous biofeedback and stress, no previous biofeedback and stress) plus 1 (no previous instructions/no previous biofeedback, no stress). Results indicated that the threat of shock was effective in increasing arousal (as measured by heart rate and skin resistance) but previous EEG-alpha biofeedback training was not effective in helping subjects decrease arousal while in the stressful situation. The results indicate that it is the instructions (and related information concerning alpha) rather than the biofeedback that is critical in alpha biofeedback training and that this training does not appear to have utility for controlling arousal under stress.     

Effects of displacing aggression by annoyed and nonannoyed subjects

Low hostility-guilt subjects were either annoyed or not annoyed by an experimental confederate and given the opportunity to (a) displace aggression against a second confederate in a memory task, (b) go through a similar task but not aggress, or (c) sit quietly for a comparable period of time. All subjects were subsequently allowed to aggress against their annoyer in a “creativity” task. While displacement following annoyance did not reduce physiological arousal, it did reduce the amount of subsequent aggression against the annoyer. Conversely, the expression of aggression in subjects who were not annoyed resulted in an increase in physiological arousal, but not in subsequent aggression. No significant relationships were found between physiological arousal and subsequent aggression.
