Severe asthma and adherence to peak flow monitoring: Longitudinal assessment of psychological aspects

BackgroundAdherence in severe asthma is a difficult health problem. Although psychosocial factors may be responsible for non-adherence, few longitudinal studies have investigated their link with adherence, with most studies having focused on pharmacology. MethodsSixty patients with severe asthma were recruited. Adherence was electronically monitored using peak flow measurements at entry and after 1 year of follow-up. Eysenck's Personality Inventory, Rotter's Locus of Control (LOC), and health control beliefs were all studied. Multiple logistic regression (MLR) was used for risk calculations. ResultsInitially, subjects with poor adherence had an external LOC (P=.001) and a high extraversion score (P=.003) compared to those with good adherence. The lie score was high in all patients. Nocturnal awakenings were highly significantly correlated with poor adherence (P=.006). After 1 year, patient adherence, extraversion, and neuroticism remained unchanged. The LOC changed in subjects with poor adherence, showing a less “external” orientation (P=.007). The health parameters were better at the end of the study. By MLR analysis, externality, extraversion, and low social desirability were associated with poor adherence. Patients with poor adherence had a greater probability of nocturnal symptoms. ConclusionNo specific personality type was associated with lack of adherence in the present study, but a high extraversion score, a low social desirability score, and a high level of externality were all predictors of poor adherence.

Differences in neuroticism and extraversion between patients with bipolar I or II and general population subjects or major depressive disorder patients

BackgroundWhether levels of neuroticism or extraversion differ between patients with bipolar disorder (BD), major depressive disorder (MDD) and subjects from the general population, or between BD I and BD II patients, remains unclear. MethodsBD patients (n=191) from the Jorvi Bipolar Study, and MDD patients (n=358) from both the Vantaa Depression Study and the Vantaa Primary Care Depression Study cohorts, were interviewed at baseline and at 18months. A general population comparison group (n=347) was surveyed by mail. BD patients’ neuroticism and extraversion scores, measured by Eysenck Personality Inventory, were compared at an index interview, when the levels of depression and mania were lowest, with scores of MDD patients and general population controls. Comparisons were also made between BD I (n=99) and BD II (n=92) patients. ResultsIn multinomial logistic regression, BD patients had higher neuroticism (OR=1.17, p<0.001) and lower extraversion (OR=0.92, p=0.003) than the general population. When entered simultaneously into the model, the effect of extraversion disappeared. In logistic regression, the levels of neuroticism and extraversion did not differ between BD and MDD patients, or between BD I and II patients. LimitationsPatients’ personality scores were not pre-morbid. ConclusionsLevels of neuroticism and extraversion are unlikely to differ between BD and MDD patients, or between BD I and II patients. The overall level of neuroticism is moderately higher and extraversion somewhat lower in BD patients than in the general population. High neuroticism may be an indicator of vulnerability to both bipolar and unipolar mood disorders.

Categorical and Dimensional Stability of Comorbid Personality Disorder Symptoms inDSM-IVMajor Depressive Disorder

To investigate the categorical and dimensional temporal stability of Axis II personality disorders among depressive patients, and to determine whether variations in Axis I comorbid disorders or self-reported personality traits predict changes in researcher-assigned personality disorder symptoms. Patients with DSM-IV major depressive disorder (MDD) in the Vantaa Depression Study (N = 269) were interviewed with the World Health Organization Schedules for Clinical Assessment in Neuropsychiatry, version 2.0, and the Structured Clinical Interview for DSM-III-R Axis II Disorders and were assessed with the 57-item Eysenck Personality Inventory at baseline, 6 months, and 18 months. Baseline interviews occurred between February 1, 1997, and May 31, 1998; follow-up interviews were 6 months and 18 months after baseline for each patient. Of the patients included in the study, 193 remained unipolar and could be interviewed at both follow-ups. The covariation of the severity of depression, anxiety, alcohol use, and reported neuroticism and extraversion with assigned personality disorder symptoms was investigated by using general estimation equations. The diagnosis of personality disorder persisted at all time points in about half (43%) of the 81 MDD patients diagnosed with personality disorder at baseline. The number of positive personality disorder criteria declined, particularly during the first 6 months, by a mean of 3 criteria. The decline in reported personality disorder symptoms covaried significantly with declines in the severity of depressive and anxiety symptoms (depressive: P = .02 for paranoid, P = .02 for borderline, and P = .01 for avoidant; anxiety: P = .08 for paranoid, P = .01 for borderline, and P < .001 for avoidant). Changes in patients' perceptions of self as measured by neuroticism covaried with changes in paranoid (P = .01) and borderline (P < .001) personality disorder symptoms. Among MDD patients, the categorical stability of concurrent personality disorder diagnoses assigned while depressed is relatively poor, but the dimensional stability is moderate. The remission of depression as well as variations in Axis I comorbidity, particularly anxiety disorders, influences personality disorder diagnoses. These diagnostic difficulties most likely reflect broader variations in patients' perceptions of self over time, not merely psychometric problems related to the pertinent diagnostic criteria.

School achievement and personality dynamics in adolescence

The purpose of this study was to identify if psychological type of personality, energetic pattern, emotional pattern and motivational structure of personality have any influence towards school achievement of adolescents. In order to achieve our goal, 100 adolescent subjects were tested, random chosen from the same high school. Our instruments were: Myer-Briggs Type Inventory, Eysenck Personality Inventory and Motivational Structure of Personality Questionnaire. To rate school achievement of subjects, we used their annual grades from previous academic year. Results showed that psychological personality type doesn’t significantly influence school performance, meaning that students, even if have or not these personality features, can have similar school achievements. Energetic pattern of personality and emotional pattern are not conditions for school performance in adolescents, but some motivational features are.

Similarities and differences between excessive exercising anorexia nervosa patients compared with DSM-IV defined anorexia nervosa subtypes

This study describes anorexia nervosa (AN) patients who use excessive exercise for weight management and how this behaviour relates to the classical Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV) sub-grouping of AN. The study compared 428 clinical AN patients with 119 age and gender-matched controls. The AN cases were initially dichotomised according to DSM-IV subtype criteria into restricting (RAN; N=198) and binge-purge (BPAN; N=230) anorexia. The psychometric instruments were chosen to reflect key features concerning the diagnosis of eating disorders and characteristics of eating and food behaviour and included the 26-item Eating Attitude Test (EAT-26), Three Factor Eating Questionnaire (TFEQ), Dutch Eating Behaviour Questionnaire (DEBQ), Eysenck Personality Inventory (EPI) and Rosenberg Self-Esteem scale (RSE). Structured clinical interviews (1) were carried out in order to identify the subgroup of patients who use excessive exercise in order to facilitate weight control (EAN). The three groups (RAN, BPAN, EAN) did not differ in measures of current age, current body mass index, age of onset of AN and measures of restrained eating. However, significant differences were observed on EAT-26, DEBQ emotional and external factors, TFEQ disinhibition and hunger factors, EPI extraversion and neuroticism, and self-esteem. The EAN were similar to the RAN on the majority of variables but showed significant differences on extraversion, neuroticism, self-esteem and disease pathology (EAT-26). Compared with BPAN, EAN had lower disease pathology (EAT-26 scores), scored higher on the EPI extraversion scale, lower on the neuroticism scale and had greater self-esteem. The EAN also displayed significantly lower emotional and external eating (DEBQ) than BPAN and significantly lower disinhibition and hunger scores (TFEQ). These data suggest that EAN group display a mixed profile of characteristics resembling both BPAN and RAN. When EAN are defined as a separate group they appear to be phenotypically more similar to RAN than BPAN on this particular profile of variables. However when DSM-IV criteria are applied they are almost exclusively classified as BPAN. This outcome suggests that EAN do constitute an identifiable group that can be distinguished from RAN and BPAN. Consequently it is likely that the behaviour of excessive exercising should be considered as clinically relevant on the outcome of treatment.

Interactions among situations, neuroticism, and appraisals in coping strategy choice

The present study investigated the interactive effects of situation types, neuroticism, and appraisals on coping with anxiety. Participants completed the Eysenck Personality Inventory to assess levels of neuroticism. They then recalled the most anxious event they had experienced and imagined they were in very similar situations. They described the situations along with their body reactions and emotions. Additionally, participants completed a questionnaire about cognitive appraisals and coping. Results showed significant interaction effects for situation types, neuroticism, and appraisals on coping activities.

Genetic contribution to the relationship between personality and depressive symptoms among older women

Prior studies suggest that certain types of personality are at higher risk for developing depressive disorders. This study examined the relationship between old age depressive symptoms and two middle-age personality dimensions, neuroticism and extraversion. The present study is part of the Finnish Twin Study on Aging, where altogether 409 female twins who had completed the Eysenck Personality Inventory at the age of 38-51 years were studied for depressive symptoms 28 years later using Center for the Epidemiologic Studies Depression Scale. Logistic regression analysis suitable for dependent data and univariate and Cholesky models for decomposing the genetic and environmental factor were used. Middle age extraversion protected from later depressive symptoms while neuroticism increased the risk. Twin modeling indicated that the association between neuroticism and depressive symptoms resulted from shared genetic risk factors common to both traits. However, a substantial proportion of the genetic vulnerability was specific to old age depressive symptoms and was not shared with neuroticism. Middle age extraversion had no genetic relationship with old age depressive symptoms. The relationship between middle age neuroticism and old age depressive symptoms is strong but only partly the result of genetic factors that predispose to both neuroticism and depressive symptoms. Extraversion, by contrast, has no genetic relationship with depressive symptoms experienced in old age.

Influence of Personality on Objective and Subjective Social Support Among Patients With Major Depressive Disorder

Personality and social support (SS) influence risk for depression and modify its outcome through multiple pathways. The impact of personality dimensions neuroticism and extraversion on SS among patients with major depressive disorder (MDD) has been little studied. In the Vantaa Depression Study, we assessed neuroticism and extraversion with the Eysenck Personality Inventory, objective SS with the Interview Measure of Social Relationships, and subjective SS with the Perceived Social Support Scale-Revised at baseline, at 6 and 18 months among 193 major depressive disorder patients diagnosed according to the fourth edition of Diagnostic and Statistical Manual of Mental Disorders (DMS-IV). At all time-points, low neuroticism and high extraversion associated significantly with between-subject differences in levels of objective and subjective SS. Lower neuroticism (beta = 0.213, p = 0.003) and higher extraversion (beta = 0.159, p = 0.038) predicted greater within-subject change of subjective, but not objective SS. Thus, neuroticism and extraversion associated with the size of objective and subjective SS and predicted change of subjective SS. Modification of subjective SS, particularly, may indirectly influence future vulnerability to depression.

Extraversion and Neuroticism and its Effect on Short and Long – Term Memory among Al-Quds Open University Students at Tulkarm Educational Region

The study aims to investigate the effect of the personality traits: Extroversion, introversion, instability (emotionality) and stability on short and long – term memory among Al-Quds Open University students at Tulkarm Educational Region. To achieve this purpose, the Eysenck Personality Inventory (EPI) was applied at a sample consisted of (200) students, and then the sample was divided into four equal groups of 25 male and 25 female for each group according to their scores on the above mentioned test: Extroverts, introverts, emotionality and stable students. After using two tests for measuring the short and long – term memory, and by using one - way analysis of variance, results show that extraverts and emotionality students are better than introverts and stable students in short- term memory, whereas the introverts and stable students are better than extraverts and emotionality in long- term memory. These results are in line with the literature review of this study.

Study of quality of life for transsexuals after hormonal and surgical reassignment

The main objective of this work is to provide a more detailed assessment of the impact of surgical reassignment on the most important aspects of daily life for these patients. Our secondary objective was to establish the influence of various factors likely to have an impact on the quality of life (QoL), such as biological gender and the subject's personality. A personality study was conducted using Eysenck Personality Inventory (EPI) so as to analyze two aspects of the personality (extraversion and neuroticism). Thirty-eight subjects who had undergone hormonal surgical reassignment were included in the study. The results show that gender reassignment surgery improves the QoL for transsexuals in several different important areas: most are satisfied of their sexual reassignment (28/30), their social (21/30) and sexual QoL (25/30) are improved. However, there are differences between male-to-female (MtF) and female-to-male (FtM) transsexuals in terms of QoL: FtM have a better social, professional, friendly lifestyles than MtF. Finally, the results of this study did not evidence any influence by certain aspects of the personality, such as extraversion and neuroticism, on the QoL for reassigned subjects.

- After an introduction on the dimensional approach in personality diagnosis and on its use as an attempt at solving some of the problems of categorical diagnoses (such as those of DSM-III and DSM-IV), the main dimensional models of personality are presented, namely: 16 PF Questionnaire by Cattell, Eysenck Personality Inventory (EPI), Five-Factor Model (FFM) by Costa &amp; McCrae (Big Five), Temperament and Character Inventory (TCI) by Cloninger, Schedule for Nondaptive and Adaptive Personality (SNAP) by Clark, Dimensional Assessment of Personality Pathology - Basic Questionnaire (DAPP-BQ) by Livesley, Structural Analysis of Social Behavior (SASB) by Benjamin, the "fundamental polarity (anaclitic and introjective) of personality" by Blatt, Shedler-Westen Assessment Procedure (SWAP). Finally, advantages and disadvantages of dimensional models are discussed, with particular emphasis on borderline disorder.key words: personality, dimensional models, categorical model, borderline, diagnosis

Pessimistic, anxious, and depressive personality traits predict all-cause mortality: the Mayo Clinic cohort study of personality and aging.

To study the association between several personality traits and all-cause mortality. We established a historical cohort of 7216 subjects who completed the Minnesota Multiphasic Personality Inventory (MMPI) for research at the Mayo Clinic from 1962 to 1965, and who resided within a 120-mile radius centered in Rochester, MN. A total of 7080 subjects (98.1%) were followed over four decades either actively (via a direct or proxy telephone interview) or passively (via review of medical records or by obtaining their death certificates). We examined the association of pessimistic, anxious, and depressive personality traits (as measured using MMPI scales) with all-cause mortality. A total of 4634 subjects (65.5%) died during follow-up. Pessimistic, anxious, and depressive personality traits were associated with increased all-cause mortality in both men and women. In addition, we observed a linear trend of increasing risk from the first to the fourth quartile for all three scales. Results were similar in additional analyses considering the personality scores as continuous variables, in analyses combining the three personality traits into a composite neuroticism score, and in several sets of sensitivity analyses. These associations remained significant even when personality was measured early in life (ages 20-39 years). Our findings suggest that personality traits related to neuroticism are associated with an increased risk of all-cause mortality even when they are measured early in life.

Personality and lifestyle in relation to dementia incidence

High neuroticism has been associated with a greater risk of dementia, and an active/socially integrated lifestyle with a lower risk of dementia. The aim of the current study was to explore the separate and combined effects of neuroticism and extraversion on the risk of dementia, and to examine whether lifestyle factors may modify this association. A population-based cohort of 506 older people with no dementia from the Kungsholmen Project, Stockholm, Sweden, was followed up for an average of 6 years. Personality traits were assessed using the Eysenck Personality Inventory. Dementia was diagnosed by specialists according to DSM-III-R criteria. Neither high neuroticism nor low extraversion alone was related to significantly higher incidence of dementia. However, among people with an inactive or socially isolated lifestyle, low neuroticism was associated with a decreased dementia risk (hazard ratio [HR] = 0.51, 95% confidence interval [CI] = 0.27-0.96). When compared to persons with high neuroticism and high extraversion, a decreased risk of dementia was detected in individuals with low neuroticism and high extraversion (HR = 0.51, 95% CI = 0.28-0.94), but not among persons with low neuroticism and low extraversion (HR = 0.95, 95% CI = 0.57-1.60), nor high neuroticism and low extraversion (HR = 0.97 95% CI = 0.57-1.65). Stratified analysis by lifestyle showed that the inverse association of low neuroticism and high extraversion in combination was present only among the inactive or socially isolated persons. Low neuroticism in combination with high extraversion is the personality trait associated with the lowest dementia risk; however, among socially isolated individuals even low neuroticism alone seems to decrease dementia risk.

P03-163 Birmingham risk, resilience, intervention treatment and evaluation project

Aim:To track the levels of emotional dysfunction, symptoms, risk and resilience factors and responses to treatment in the Ultra High Risk (UHR) group.Background:There has been an increasing interest in the study, detection and treatment of individuals at UHR of developing psychosis. MacGorry et al. (2003) have put forward criteria for identifying UHR, who have been found to have a 40% chance of making the transition to psychosis within one year (Yung et al., 1998). Research trials are ongoing to study whether CBT can prevent these individuals from developing psychosis completely, or at least delay its onset (Morrison et al., 2005).Method:100 participants (16-35 years old) were recruited and assessed from the Early Detection and Intervention Team (ED: IT) over a two-year follow-up period. Inclusion criteria were based on the SIPS (McGlashan et al., 2002). Participants were asked to complete questionnaire measures at baseline, 6-month and 12-month follow-up. the baseline measures were: Beck Anxiety Inventory; Beck Depression Inventory; Dissociative Experience Scale; Social Comparison Scale; Social Phobia Scale; Social Interaction Anxiety Scale and Eysenck Personality Inventory. the follow-up measures were: Trauma and Distress Scale; Childhood Trauma Questionnaire; other as Shamer; MOPS, RAAS: Pathways to care; Premorbid Adjustment Scale; Chart of life events and Schizotypal Personality Questionnaire.Results:Study is still ongoing.Discussion:Our preliminary findings seem to suggest that different risk factors have consistent detrimental effects on mood regulation and symptom contention. It might be possible to manage these factors in at-risk clients in psychological therapy.

P03-227 Personality traits and sleep patterns/problems in medical students

Aim:This study examines the relationship between the personality traits of Neuroticism and Extroversion and sleep patterns and others sleep behaviours in medical students.Method:Neuroticism and Extroversion were assessed using the Portuguese version of the Eysenck Personality Inventory. Sleep was assessed with a self-response questionnaire covering a wide range of sleep-wake habits and difficulties. A factor analysis with varimax rotation was performed with seventeen items of the questionnaire and four factors were extracted: Sleep Disturbance, Sleep Timing, Insufficient Sleep and Dreams/Nightmares. A total of 203 third year medical students (127 females, 62.6%) mean age 20.01 (SD=1.09; Range=18-24) participated in the study.Results:There were no significant gender differences in Neuroticism and Extroversion mean scores (Neuroticism: p=.454; Extroversion: p=.891). Extroversion was significantly correlated with Sleep Timing (p=.000), whereasthere was a trend for Neuroticism to be associated with Sleep Disturbance (p=.095). Concerning the relationship of Neuroticism and Extroversion mean scores with other Sleep problems, Neuroticism was found associated with concentration difficulties in the morning (p=.006), inadequate sleep duration (p=.001), sleep problems (p=.012), and use of sleep medication (p=.052). No significant associations were found with Extroversion.Conclusion:Neuroticism was significantly associated with sleep problems, use of sleep medication, inadequate sleep duration, and concentration difficulties in the morning. Extroversion was correlated only with later Sleep Timing.

The personality trait of neuroticism is strongly associated with long-term morbidity in testicular cancer survivors

Background. Neuroticism is a personality trait expressing nervousness and insecurity. Associations between neuroticism and morbidity in long-term cancer survivors have hardly been explored. The aim of this study was to explore associations between neuroticism and somatic and mental morbidity and lifestyle issues in long-term survivors of testicular cancer (TCSs). Material and methods. All Norwegian TCSs treated between 1980 and 1994 (n = 1 814) were invited to this cross-sectional study. Among them 1 428 (79% response rate) delivered valid data. Neuroticism was self-rated on an abridged version of the Eysenck Personality Inventory. Information was collected by mailed questionnaires. The associations of neuroticism and self-reported variables were tested with multivariate logistic regression analyses. Results. Neuroticism was significantly associated with presence of somatic complaints, reduced physical function, neurotoxic side-effects (tinnitus, hearing impairment, peripheral neuropathy, and Raynaud's Phenomenon), self-esteem, concerns about not being able to father children, sexual problems, hazardous alcohol use, daily use of medication, use of sedatives and hypnotics, recent visits to a general practitioner, and seeing a psychologist/ psychiatrist after ended cancer treatment. Poor self-rated health, higher number of negative life events, economical problems and problems getting loans granted showed significant associations with neuroticism. Discussion. Neuroticism in TCSs at long-term follow-up is significantly associated with somatic and mental morbidities, and several aspects of unhealthy lifestyle. High levels of neuroticism should be considered in TCSs expressing multiple complaints and concerns at follow-up consultations. Assessment of neuroticism may be clinically important in order to offer appropriate interventions to prevent and manage morbidity in TCSs.

Psychological vulnerability differences in students—Carriers or not of the serotonin transporter promoter allele S: Effect of adverse experiences

To study the effect of the serotonin transporting gene L/S polymorphism on several psychological characteristics in a group of Greek University students. One hundred eighty-one students were genotyped and classified into two groups: carriers or noncarriers of an S allele. Students were evaluated with a battery of psychological tests (Zung depression rating scale, symptoms check-list-90-R, Eysenck personality inventory); they also answered questionnaires regarding serious past adverse experiences as well as nicotine and alcohol use. Multivariate analysis of variance (MANOVA) was used to check the main effect of genotype and its interaction with both adverse life experiences and scores of psychological tests. No significant differences were detected between the two groups of students regarding scores of the psychological tests. Yet, analysis with MANOVA indicated an interaction between genotype and adversities (lambda = 0.838, F(17,158) = 1.802, P = 0.032). Students who both carry at least one S allele and have faced serious past adverse life experiences have scored higher than carriers of the S allele who have not faced adversities on the following: global severity index (F(1174) = 5.973, P = 0.016), positive symptoms distress index (F(1174) = 4.518, P = 0.035), somatization (F(1174) = 4.074, P = 0.045), depression (F(1174) = 4.971, P = 0.027), anxiety (F(1174) = 8.112, P = 0.005), phobic anxiety (F(1174) = 16.421, P < 0.000), and paranoid ideation (F(1174) = 5.143, P = 0.025). Among students without adversities, those with the LL genotype have scored higher than S allele carriers on the following: depression (t = 2.680, df = 75, P = 0.009), anxiety (t = 2.629, df = 75, P = 0.010), phobic anxiety (t = 3.350, df = 75, P = 0.001), and paranoid ideation (t = 2.668, df = 75, P = 0.009). The S and L alleles seem to interact differently with serious past life adversities in influencing psychological vulnerability. Adversities seem to have a stronger effect on S carriers. LL genotype might be related to the expression of certain more endogenous psychopathological tendencies.

A cross‐sectional study of psychological morbidity in patients with acne, psoriasis and atopic dermatitis in specialist dermatology and general practices

There is considerable evidence for an association of skin diseases with psychological morbidity. This relationship is best established for acne, psoriasis and atopic eczema. Previous studies have mostly been performed in specialist dermatological practice, and there is a lack of studies that include patients from general practice and a lack of controlled studies employing multivariate analysis. This study aims to examine the relationship of acne, psoriasis and atopic eczema with psychological morbidities in patients recruited from general practice as well as specialist dermatology practice. In this cross-sectional study, 108 patients from general and specialist dermatology practices with the three diseases had disease severity assessed and completed measures of minor psychological disturbance (General Health Questionnaire-12), anxiety and depression (Hospital Anxiety and Depression Scale), public self-consciousness and social anxiety (Fenigstein Self-Consciousness Scale), and neuroticism and extraversion/introversion (Eysenck Personality Inventory). Demographic data were also collected, along with self-ratings of disease severity. Control subjects were 96 patients without skin disease recruited from the same general practices as the subjects. On univariate analyses, patients with skin disease had higher levels of minor psychological disturbance, public self-consciousness and neuroticism than did controls. There were no differences in psychological measures between specialist and general practice patients or between patients with different skin diseases. On multivariate analyses, the significant differences did not persist. This study demonstrates confounding in the relationship of skin diseases with psychological morbidity. The complex relationship of skin disease and psychological morbidity should be re-examined.

Psychological and psychiatric factors related to health-related quality of life after total hip replacement – preliminary report

Abstract Total hip replacement is one of the most successful orthopaedic interventions in improving considerably the patients' performance, nevertheless some patients demonstrate declined functional ability following an operation. Such condition is not a consequence of medical illness or the surgery itself but might rather be associated with mental status. The authors conduct an investigation concerning the relation between some psychological and psychiatric factors and their influence on health-related quality of life in patients after total hip replacement. Methods Into the study group we included 102 subjects undergoing total hip replacement (59 female, 43 male). In all subjects we measured depression (Beck Depression Inventory – BDI), anxiety (State and Trait Anxiety Inventory – STAI), sense of coherence (SOC-29), personality traits (Eysenck Personality Inventory – EPI) and health related quality of life (SF-36). Results The postoperative values of the PCS and the MCS for the whole group of patients correlated negatively with the SOC values ( p = 0.04 and p = 0.03 respectively). Neuroticism (EPI) and anxiety as a trait (STAI) were also associated with postoperative performance, both in mental ( p = 0.03 and p = 0.008 respectively) and physical ( p = 0.005 and p = 0.04 respectively terms). Conclusion Total hip replacement improves significantly the patient's health-related quality of life at 6 months after surgery, what is influenced by sense of coherence, neuroticism and anxiety as a trait. Above mentioned factors should be taken into account when rehabilitation and social readaptation processes are planned.
