Personality and chronic fatigue syndrome: The role of the five-factor model

The aim of this study was to examine the relationships between personality factors and the symptomatology of fatigue among people with chronic fatigue syndrome (CFS), and compare them to people from the general population. Seventy-seven CFS patients (47 women, 30 men) were compared with 72 healthy individuals (44 women, 28 men) to investigate whether personality factors are related to the symptomatology of fatigue. All participants were asked to complete the NEO Five Factor Inventory (NEO-FFI), the Modified Fatigue Impact Scale (MFIS), the Fatigue Severity Scale (FSC), and the Mental Health Inventory (MHI). The results revealed that the CFS group reported higher levels of neuroticism and conscientiousness than the control group. These two personality factors were significantly related to fatigue symptoms, impact, and severity in both groups. These findings suggest that personality factors of neuroticism and conscientiousness may play an important role in the development and perpetuation of fatigue symptoms.

Research on relationship of the procrastination and the big five personality factors in university students

Objective To study the relationship of the university students' procrastination and big five personality factors.Methods 461 university students were assessed by the simple edition of tuckman procrastination scale(TPS) and the big five personality inventory short form(NEO-FFI).Results TPS score of the student was (48.51 ± 7.66).There were 89.4% students respectively had different level of procrastination behavior.There were no significant differences in university students by the gender(47.95 ±7.84 vs 48.95 ± 7.43 ) ,whether one-child students(48.64 ± 7.49 vs 48.45 ± 7.81 ) and grades.There were significant positive correlation between procrastination and the personality factor of neuroticism( r=0.235, P＜0.01 ) and significant negative correlation with extraversion ( r=-0.180, P ＜ 0.01 ) and conscientiousness ( r =-0.198, P ＜ 0.01 ).The big five personality factors of neuroticism,extraversion and conscientiousness could explain the 14.0% variation of procrastination of university students.Conclusion Procrastination is a very common phenomenon in the university students.The students with higher neuroticism, lower extraversion and conscientiousness of big five personality have more procrastination behavior. Key words: University students; Procrastination; Big five personality

Is Personality a Key Predictor of Missing Study Data? An Analysis From a Randomized Controlled Trial

Little is known regarding the effects of psychological factors on data collection in research studies. We examined whether Five Factor Model (FFM) personality factors-Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness-predicted missing data in a randomized controlled trial (RCT). Individuals (N = 415) aged 40 years and older with various chronic conditions, plus basic activity impairment, depressive symptoms, or both, were recruited from a primary care network and enrolled in a 6-week RCT of an illness self-management intervention, delivered by means of home visits or telephone calls or usual care. Random effects logistic regression modeling was used to examine whether FFM factors predicted missing illness management self-efficacy data at any scheduled follow-up (2, 4, and 6 weeks, and 6 and 12 months), controlling for disease burden, study arm, and sociodemographic characteristics. Across all follow-up points, the missing data rate was 4.5%. Higher levels of Openness (adjusted odds ratio [AOR] for 1-SD increase = 0.24; 95% CI, 0.12-0.46; P <.001), Agreeableness (AOR = 0.29; CI 0.14-0.60; P=.001), and Conscientiousness (AOR = 0.24; CI 0.15-0.50; P <.001) were independently associated with fewer missing data. Accuracy of the missing data prediction model increased when personality variables were added (change in area under the receiver operating characteristic curve from 0.71 to 0.77; chi(2)(1)=6.6; P=.01). Personality was a powerful predictor of missing study data in this RCT. Assessing personality could inform efforts to enhance data completion and adjust analyses for bias caused by missing data.

Los Big Five y el Efecto Moderador de la Resistencia en el Agotamiento Emocional

The aim of this study is to the relationship between personality (Big Five) and resilience, with emotional exhaustion in a diverse sample. The sample is 311 workers from different sectors, but predominantly within the service sector. We use MBI, BFI and CD-RISC, as instruments in a cross-sectional design study. As expected by previous studies, we have found significant associations between ed variables.. Moreover, we found that resilience acted as a moderator variable between personality and emotional exhaustion, as results has shown a significant interaction between Resilience and Conscientiousness. By multiple regression analysis, we obtained the predictive capability of the personality factor Neuroticism, Resilience, and the product of Conscientiousness and resilience. Consequently, it highlights the importance of personality in the core dimension of burnout, emotional exhaustion. Further, resilience is a promising variable to be considered in organizational and employment studies. This is relevance as few studies have addressed this problem.

Nightmares: from anxiety symptom to sleep disorder

The DSM-IV-TR definition of nightmares-extremely frightening dreams from which the person wakes up directly-is unnecessarily narrow. Other emotions (anger, grief) have also been reported in nightmares, and direct awakening from a bad dream seems to be unrelated to increased distress. In addition, assessment of nightmares is problematic. Polysomnographic recordings have an ameliorating effect on nightmare frequency, retrospective measurements tend to underestimate nightmare frequency, and persons with frequent nightmares may feel reluctant to fill out (daily) prospective measurements. For studying nightmares, it is necessary to distinguish idiopathic nightmares from posttraumatic nightmares, which are part of a posttraumatic stress reaction or disorder that may result from experiencing a traumatic event. Both types of nightmares have been associated with an elevated level of periodic limb movements, although only posttraumatic nightmares seem to be related to more and longer nocturnal awakenings. Nightmares have also been repeatedly associated with the general level of psychopathology, or the so-called personality factor neuroticism. Nightmare distress, the impact on daily functioning caused by nightmares, may function as a mediating variable. Several studies in the last decades have shown that nightmares can be treated with several cognitive-behavioral techniques. The cognitive-restructuring technique imagery rehearsal therapy is the treatment of choice for nightmares, although a randomized controlled trial with an attention control-group has not yet been carried out. Nightmares are more than a symptom of a larger (anxiety) syndrome and need to be viewed from a sleep medicine perspective: nightmares are a highly prevalent and separate sleep disorder that can and should receive specific treatment.

The influence of socio-demographic factors on personality dimensions in the elderly

The personality factors neuroticism, extraversion, openness for experiences, agreeableness and conscientiousness were investigated in a random population sample of n=497 people over 60 years old with the help of a German version of the NEO Five-Factor Inventory - NEO-FFI (2, 6). The results were compared with those from n=497 people between 18 and 30 years old and with those from n=1051 people between 31 and 60 years old. The elderly described themselves as being less extroverted, less open, more agreeable and more conscientious than the people under 60 years old. Means of the personality factors were not associated with age in the over 60 years old. The average level of neuroticism and conscientiousness was significantly higher in women over 60 years old than in men. People living in the former Eastern Germany were more open and conscientiousness than those living in former Western Germany. A higher level of openness was found in people with a higher educational level. There was a higher level of neuroticism in people living without a partner than in those living with a partner.

Cloninger's temperament and character inventory and the NEO Five-Factor Inventory.

A principal axis factor analysis was performed jointly for the seven Temperament and Character Inventory scales and the five NEO Five-Factor Inventory scales, using 95 male and 109 female introductory psychology students. The five factors obtained were similar to the five major personality factors of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness, and supported the comprehensiveness of the five-factor model of personality.

On the conceptualisation of subaffective personality disorders

The reconceptualisation of German traditional constructs of subaffective personality disorders (PDs) was stimulated by clinical and some empirical evidence of mild and enduring alterations of mood and drive in patients who never developed one of the full-blown mood disorders. The aim of the study was to clarify the status of historical concepts of subaffective PDs (as there are the depressive, hyperthymic, cyclothymic, and asthenic type) in relation to the modern Diagnostic and Statistical Manual (DSM)-III-R conceptions of personality disorders and the five factor theory of personality. A consecutive psychiatric sample and a normal control sample were used to investigate these relationships. By means of a non-metric multi-dimensional scaling procedure, and facet theoretical interpretation, the depressive and asthenic PDs were demonstrated to correspond highly with the global construct of PD as well as with the personality factor neuroticism which proved to be elevated in most types of PDs within the clinical sample. The hyperthymic and cyclothymic categories displayed differences to most DSM-III-R constructs of PD in the clinical but not in the control sample. The findings may explain the chronic course of some depressive or somatization disorders that are difficult to influence by pharmacotherapy and that may require special treatment strategies.
