Impact of personality and psychological distress on health-related quality of life in kidney transplant recipients

Health-Related Quality of Life in pre-dialysis patients with chronic kidney disease: the role of Big-Five personality traits and illness denial

BACKGROUND

Health-Related Quality of Life (HRQoL) in patients with chronic kidney disease (CKD) is significantly affected, regardless of the stage of the disease, as regards the physical, psychological and social functioning dimension. Big-Five personality traits can affect patients' HRQoL and willingness to take treatment options. Illness denial consists of denial of negative emotions, resistance to change and conscious avoidance. Poorer HRQoL can predict a higher risk of hospitalization and mortality, and broadly a worse adjustment to the dialytic therapy. Thus, a clearer knowledge of the psychological variables associated with a worse HRQoL in the predialysis stage might improve the intervention planning. No study investigated illness denial and personality traits simultaneously. We investigated the role of illness denial and Big-Five personality traits in the domains of HRQoL in predialysis patients with CKD.

METHODS

One hundred adults (mean age: 75.87 years) with CKD participated. The Kidney Disease Quality of Life Short form, the Italian version of Ten Item Personality Inventory Revised, the Illness Denial Questionnaire, and the State-Trait Anxiety Inventory Form-Y were administered.

RESULTS

Illness denial was associated with increased HRQoL related to symptoms/problems, effect and burden of CKD and cognitive functions domains, and it was a predictor of higher HRQoL in the last three domains mentioned above. Extraversion was related to better work status and sexual function; agreeableness was linked to elevated cognitive function, quality of social interaction and sexual function; conscientiousness was related to better sexual function; neuroticism was linked to improved cognitive and sexual functions; in the end, openness to experience was related to fewer symptoms and problems.

CONCLUSIONS

This is the first study which simultaneously assessed Big-Five personality traits and illness denial in different domains of HRQoL of CKD patients. Personalised psychological interventions aimed at improving HRQoL in this population might focus on specific illness denial processes and personality traits.

Psychosocial treatment on psychological symptoms, adherence, and physiological function on transplanted patients: A systematic review and metanalysis

OBJECTIVE

Transplantation represents an important source of hope for the candidates and produces an intense emotional effect. Psychosocial interventions can be helpful in all transplantation stages to better manage this extraordinarily stressful situation. Aim of the work is to verify the effects of the psychosocial interventions on recipients on psychological symptoms, medical adherence and transplanted solid organ functioning.

METHODS

This work adhered to PRISMA, STROBE, Cochrane and New Castle Ottawa bias scales and it is registered in PROSPERO. Inserting "Transplant" and "Psychological intervention" as key words in PubMed, Psycinfo, Cochrane database resulted 977 studies from 2001 to 2021. A systematic review and metanalyses were processed on nineteen randomized controlled trials and observative prospective cohort studies. The difference between pre- and post- psychosocial intervention assessment on the psychological variables, medical adherence, and organ functioning outcome was processed.

RESULTS

Main findings showed that the psychosocial interventions were effective on depression (0.62; CI: 0.32-0.92) and anxiety on kidney recipients (0.49; CI: 0.17-0.81), and on anxiety on heart recipients, mainly when administrated after the surgery (0.68; CI: 0.30-1.06). Moreover, the findings showed a lack of studies on the effectiveness of the psychosocial intervention on organ functioning.

CONCLUSION

The work highlighted the effectiveness of the psychosocial interventions on psychological outcome, particularly after the surgery and the need to address the research on the evaluation of the effectiveness of the psychosocial interventions on the organ functioning. The findings suggest to integrate the transplantation procedures with psychosocial interventions considering the different needs of recipients in relation to the specific transplanted organ.

Influence of the Expression of Personality Traits on Growing Intensity of Interdialytic Disorders and Change of Pro-Health Behaviors in Patients with Chronic Kidney Disease

Background

The aim of this study was to assess the influence of socio-demographic and clinical factors on personality trait expression and their relationship with more intense interdialytic disorders and changes in health behaviors of patients with chronic kidney disease (CKD).

Material/Methods

A total of 200 participants were recruited for the research (84 women and 116 men; aged 61±12 years): 160 patients had CKD stage G4–G5 and 40 healthy participants constituted a control group. A diagnostic poll method was used in the research employing the following questionnaires to collect socio-demographic and clinical data: Health Behavior Inventory (IZZ), Personality Inventory (NEO-FFI), Beck Depression Inventory (BDI), and Researcher’s Questionnaire Test.

Results

Statistically significant differences were found in the intensity of personal traits at different stages of treatment. The influence of factors resulting from CKD on the expression of personality traits increased with subsequent stages of treatment. Depression intensity was not connected with the expression of personality traits. A higher frequency of reported interdialytic disorders was significantly related to a higher degree of openness and conscientiousness and a lower degree of agreeableness. Increased extraversion, conscientiousness, and openness were significantly correlated with more intense health behaviors.

Conclusions

Personalities of patients with CKD changed with subsequent stages of treatment and were influenced by socio-demographic and clinical factors. Personalities affected the frequency of reported interdialytic disorders and health behaviors.

Health-related quality of life in patients with chronic kidney disease

Introduction: In the last three decades, health systems have continued to pay increasing attention to the quality of life (QOL) due to definitional changes in the concept of health and disease. The health-related quality of life (HRQOL) in patients with chronic kidney disease (CKD) is significantly affected, regardless of the stage of CKD. Areas covered: We attempt to thoroughly explore how CKD affects HRQOL domains with a quick primer on HRQOL assessment instruments in patients with CKD. Also, we pointed out the factors affecting HRQOL in patients with CKD as well as the clinical application of HRQOL in CKD management. Expert opinion: The general population enjoys higher HRQOL than patients with CKD in all domains. Similarly, pre-dialysis and kidney-transplant patients have better HRQOL than dialysis population. There are many factors which negatively impact HRQOL in CKD which include for example depression, anxiety, and cognitive impairment for the social domain, inactivity, and frailty for the physical domain as well as lack of social support and extroversion in the social domain. Additionally, social disparities and CKD-related factors would influence HRQOL. Of note, there is no global standard HRQOL assessment tool. Finally, HRQOL should be included in future CKD management guidelines.

Analysis of Psychopathologic Elements as a Compliance Limitation: Team Work as a Therapeutic Response

INTRODUCTION

The psychological evaluation of the patient, carried out through psychodiagnostic tests, clinical interviews, and a joint work with the medical-surgical team, provided useful information to assess the compliance of the kidney transplant recipient.

METHODOLOGY

Two hundred and forty-five visits were carried out between September 2018 and May 2019 in the General Surgery and Organ Transplant Department of the San Salvatore Hospital, L'Aquila. The visits consisted of clinical interviews, targeted psychodiagnostic evaluations, graphic-projective tests, and personality and cognitive structure evaluation tests. These assessments were key not only to defining the patient's personality picture but also to offering suitable psychological support to patients on waiting lists for transplantation, during hospitalization, and during follow-up visits from transplantation phases.

RESULTS

From the analysis of the tests and from the clinical and support interviews, some of the patients presented forms of psycho-emotional immaturity that impaired the predisposition to compliance and ultimately the establishment of the therapeutic alliance. During 8 months, 18 compliance limit cases were observed, 5 patients were sent to mental health centers, and 13 psychological support courses were activated within the Regional Transplant Center-Abruzzo Region Molise Region. No structured psychological support courses were deemed necessary for 9 of these 13 cases, whereas 4 were sent to the mental health centers.

CONCLUSIONS

By assessing the complexity of each patient from a medical and a psychological point of view and by considering the high number of transplant surgeries currently occurring, it can be noted that compliance to therapy is strongly linked to the reliability of the relationships between patients and caregivers.

Psychological and Psychopathological Aspects of Kidney Transplantation: A Systematic Review

Kidney transplantation is a serious event that involves profound psychological, relational and social changes both for the patient and his family context. Assessment of personality profile, awareness of disease, family and social support of the patient candidate for kidney transplantation are necessary because factors not adequately considered, can influence the success of the transplant and alter the psychological stability of the patient. The present study aims to provide a systematic review of the literature of the last twelve years (2006-2018), focusing in particular on patient's readiness level and illness management and on possible psychopathology. Sixty-two studies were examined. Based on the Downs and Black checklist, most studies (n = 32) were of high quality; 15 of which related to lifestyle, health education, and therapeutic adherence in post-renal transplantation, 17 studies concerned the possible existence of psychopathology and cognitive impairment of renal deceased transplanted subjects. The literature used has shown that the population of kidney transplant patients is exposed to a high risk of psychiatric disorders with repercussions on the quality of life and the risk of rejection. Therefore, an adequate pre-transplant psychosocial assessment is necessary, which allows a more in-depth knowledge of the candidate to plan coping strategies and possible post-transplant psychotherapy.

Barriers to Treatment Adherence Among College Students with Attention-Deficit/Hyperactivity Disorder

OBJECTIVE

The current study sought to obtain a longitudinal perspective of and quantitatively assess barriers to medication adherence experienced by college students with attention-deficit/hyperactivity disorder (ADHD). Thus, we examined semester-long trends in barriers to adherence in addition to the relationships between barriers and medication adherence and barriers and quality of life.

METHODS

Participants were college students diagnosed with ADHD. Throughout a Fall semester, participants completed 4 sets of online questionnaires and attended 4 in-person visits, which included pill counts and written questionnaires. Participants completed measures assessing barriers to adherence and health-related quality of life, and adherence was measured via pill counts. Mean values of barriers, adherence rate, and quality of life were used for all analyses.

RESULTS

Of the 45 students surveyed, mean adherence rate was 56.70%, and 84.45% of participants reported at least 1 barrier. Across the semester, participants reported experiencing an average of 3.07 barriers, and a consistent barrier reported was not realizing when pills run out. Although reported barriers were unrelated to adherence, the results showed that barriers were associated with lowered quality of life, specifically lower overall quality of life in addition to lower emotional functioning, psychosocial health, school functioning, and physical functioning.

CONCLUSION

Barriers to adherence appear to be common in college students with ADHD, and certain barriers are consistent with the planning difficulties observed in individuals with ADHD. Because students experiencing more barriers had lower quality of life, interventions are needed to improve students' overall illness management experience.

Quality of Life, Adherence Behavior, and Social Support Among Renal Transplant Recipients in China: A Descriptive Correlational Study

BACKGROUND

Quality of life (QoL) is an important indicator for evaluating therapeutic outcomes and mortality in renal transplant recipients, but there is scarce information regarding QoL, adherence behavior, social support and their relationships. This study assessed these factors among renal transplant recipients.

METHODS

Using a descriptive, correlational, cross-sectional design, this study included a convenience sample of 253 kidney transplant recipients. Structured questionnaires were used to collect data.

RESULTS

The scores on QoL domains (except the social functioning domain [P = .909]) were lower in our recipients than in the general Chinese population norm (P = .0000001). Time since transplantation (P = .041) and education (P = .013) were factors affecting QoL scores. The mean total adherence behavior score was 60.64 ± 7.71. Occupation and time since transplantation affected the total adherence behavior score. There was an alarming percentage of nonadherence in our transplant recipients (27.5%-72.3%). The mean total social support score was 40.76 ± 9.51. The total social support score (P = .0000087) was lower than the general Chinese population norm. Occupation (P = .0000087) education (P = .010), marital status (P = .013), payment method (P = .028) and monthly income (P = .007) affected the total social support score; there were significant relationships between physical health, psychological health, adherence behavior (r = .145, P = .022; r = .153, P = .016), and social support (r = .211, P = .001; r = .301, P = .000).

CONCLUSIONS

The findings demonstrate somewhat deficient QoL among renal transplant recipients compared with the general population. Social support, adherence behavior, time since transplantation and education significantly influenced QoL for our recipients, and social support had the most significant influence on adherence behavior and QoL.

Benefit finding in renal transplantation and its association with psychological and clinical correlates: A prospective study

Objectives

The identification of positive psychological changes, including benefit finding (BF), in chronic illness has gained substantial interest. However, less is known about BF in the context of a positive medical intervention. End‐stage renal disease (ESRD) can be regarded as a burdensome condition, but transplantation is expected to restore physical and psychological functioning to a large extent after a period of illness. The aim of this study was to examine (1) changes in BF from pre‐ to 12 months post‐transplantation, (2) the concurrent association of disease‐related characteristics and optimism to BF, and (3) the potential causal relations between BF and distress.

Methods

In this longitudinal study, 319 patients completed questionnaires before, 3 months, 6 months, and/or 12 months post‐transplantation. Multilevel models were used for the analyses. Measures included the Illness Cognitions Questionnaire to measure BF, the Life Orientation Test to measure optimism, and the General Health Questionnaire to measure distress.

Results

Benefit finding increased from pre‐ to post‐transplantation. Fewer symptoms and comorbidities, and more optimism, were related to more BF over all time‐points. The direction of the relation between BF and distress changed over time. Before transplantation, distress predicted an increase in BF, whereas post‐transplantation, distress predicted a decrease in BF. The causal relation between BF and distress post‐transplantation appeared to be reciprocal.

Conclusions

A positive medical intervention such as renal transplantation might facilitate the development of BF. This study indicates the need for longitudinal research on the relation between BF and psychological health in the face of positive events.

Associations with Wellbeing and Medication Adherence in Young Adults Receiving Kidney Replacement Therapy

BACKGROUND AND OBJECTIVES

Young adults receiving kidney replacement therapy (KRT) have impaired quality of life and may exhibit low medication adherence. We tested the hypothesis that wellbeing and medication adherence are associated with psychosocial factors.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We conducted a cross-sectional online survey for young adults on KRT. Additional clinical information was obtained from the UK Renal Registry. We compared outcomes by treatment modality using age- and sex-adjusted regression models, having applied survey weights to account for response bias by sex, ethnicity, and socioeconomic status. We used multivariable linear regression to examine psychosocial associations with scores on the Warwick-Edinburgh Mental Wellbeing Scale and the eight-item Morisky Medication Adherence Scale.

RESULTS

We recruited 976 young adults and 64% responded to the survey; 417 (71%) with transplants and 173 (29%) on dialysis. Wellbeing was positively associated with extraversion, openness, independence, and social support, and negatively associated with neuroticism, negative body image, stigma, psychologic morbidity, and dialysis. Higher medication adherence was associated with living with parents, conscientiousness, physician access satisfaction, patient activation, age, and male sex, and lower adherence was associated with comorbidity, dialysis, education, ethnicity, and psychologic morbidity.

CONCLUSIONS

Wellbeing and medication adherence were both associated with psychologic morbidity in young adults. Dialysis treatment is associated with poorer wellbeing and medication adherence.

Hemodialysis Clinic Social Networks, Sex Differences, and Renal Transplantation

This study describes patient social networks within a new hemodialysis clinic and models the association between social network participation and kidney transplantation. Survey and observational data collected between August 2012 and February 2015 were used to observe the formation of a social network of 46 hemodialysis patients in a newly opened clinic. Thirty-two (70%) patients formed a social network, discussing health (59%) and transplantation (44%) with other patients. While transplant-eligible women participated in the network less often than men (56% vs. 90%, p = 0.02), women who participated discussed their health more often than men (90% vs. 45.5%, p = 0.02). Patients in the social network completed a median of two steps toward transplantation compared with a median of 0 for socially isolated patients (p = 0.003). Patients also completed more steps if network members were closely connected (β = 2.23, 95% confidence interval [CI] 0.16-4.29, p = 0.03) and if network members themselves completed more steps (β = 2.84, 95% CI 0.11-5.57, p = 0.04). The hemodialysis clinic patient social network had a net positive effect on completion of transplant steps, and patients who interacted with each other completed a similar number of steps.

Changes of perceived control after kidney transplantation: a prospective study

AIMS

The aim of this study was to determine if kidney transplantation is associated with increases of perceived control and how changes of perceived control affect the course of psychological distress until 1 year after transplantation.

BACKGROUND

Low levels of perceived control are associated with reduced well-being among dialysis patients.

DESIGN

Prospective longitudinal cohort study.

METHODS

Perceived control (Mastery Scale) and psychological distress (GHQ-12) were prospectively assessed before (T0; n = 470) and three (T1; n = 197), six (T2; n = 210) and twelve (T3; n = 183) months after transplantation. Differences between T1 and T0 perceived control were used to stratify the sample into three groups (control gain, stable control and control loss). Socio-demographic and clinical variables, including complications, were examined as potential correlates and the course of psychological was distress compared across groups. Data were collected between July 2008 - July 2013.

RESULTS

Perceived control showed a small increase overall, with 35·1%, 50·0% and 14·9% reporting gain, stable level and loss respectively. Patients with secondary schooling were overrepresented in the control loss group. The course of psychological distress varied across perceived control change groups, with patients in the control gain group experiencing a significant reduction in psychological distress.

CONCLUSION

A considerable number of patients report increased levels of perceived control after transplantation that are associated with a subsequent decrease in psychological distress. Results emphasize the importance of perceived control and could inform interventions to facilitate well-being after kidney transplantation.

Psychological perspective of medication adherence in transplantation

AIM

To identify the risk factors and the post-transplant psychological symptoms that affect adherence to therapy in a population of kidney transplant recipients.

METHODS

The study examined the psychological variables likely responsible for the non-adherent behavior using a psychological-psychiatric assessment, evaluation of the perception of patients’ health status, and an interview regarding the anti-rejection drug therapy assumption. The study included 74 kidney transplant recipients.

RESULTS

Individuals with a higher level of education and more years since transplantation showed better mental balance. Regarding gender, women appeared to be less adherent to therapy. Further, the years since transplantation adversely affected the proper pharmacological assumption. Adherence to therapy did not significantly change with the mental health index.

CONCLUSION

The biopsychosocial illness model provides a conceptual frame of reference in which biological, psychological, and social aspects take on the same importance in the adherence to treatment protocols. For effective management, it is necessary to understand the patients’ personal experiences, their assumptions about the disease, health status perception, and mood, and to identify any “barriers” that could cause them to become noncompliant.

Personality traits and clinical/biochemical course in the first year after kidney transplant

BACKGROUND

The relationship between personality and health is frequently studied in scientific research. This study investigated the clinical/biochemical course of kidney transplant patients based on personality traits.

METHODS

A longitudinal study assessed 114 kidney transplant patients (men = 68 and women = 46) with an average age of 47.72 years (SD = 11.4). Personality was evaluated using the Brazilian Factorial Personality Inventory (BFP/Big Five Model). Clinical variables were analyzed based on patient charts (estimated glomerular filtration rate (eGFR), hypertension, acute rejection, infection, graft loss, and death). Personality types were assessed by hierarchical cluster analysis.

RESULTS

Two groups with personality types were differentiated by psychological characteristics: Cluster 1 - average neuroticism, high surgency, agreeableness and conscientiousness, and low openness; Cluster 2 - high neuroticism, average surgency and agreeableness, average conscientiousness, and low openness. There was no statistically significant difference between the clusters in terms of hypertension, acute infection, graft loss, death, and Human Leukocyte Antigen (HLA) I and II panel reactive antibodies. eGFR was associated with the personality types. Cluster 2 was associated with a better renal function in the 9-month follow-up period after kidney transplantation.

CONCLUSION

In this study, patients from Cluster 2 exhibited higher eGFR 9 months after the transplant procedure compared to those from Cluster 1. Monitoring these patients over a longer period may provide a better understanding of the relationship between personality traits and clinical course during the post-transplant period.

Psychosocial well-being after kidney transplantation: A matched-pair case-control study

A number of outcome studies showed that kidney transplantation is associated with improvements in health-related quality of life relative to the pre-transplant period, but comparisons with the general population produced mixed results. This study aimed to compare 30 successful (>1 year) kidney transplantation recipients with 30 matched-pair healthy controls on psychosocial well-being. Independent of gender, age and time since transplantation, transplanted patients equalled healthy people in the intrapersonal domains but scored worse in the interpersonal domains of psychosocial well-being. Identifying aspects of life that remain impaired after kidney transplantation may assist the development of interventions targeted at improving patients’ adjustment.

Validation of the psychometrics properties of a French quality of life questionnaire among a cohort of renal transplant recipients less than one year

BACKGROUND

Renal transplantation is considered as the treatment of choice for patients with end-stage renal disease. Health-related quality of life (HRQoL) of renal transplant recipients (RTR) is very important to assess, especially during the first year after transplantation. To provide new evidence about the suitability of HRQoL measures in RTR during the first post-transplant year, we explored the internal structure, reliability and external validity of a French specific HRQoL instrument, the Renal Transplant Quality of life Questionnaire Second Version (RTQ V2).

METHODS

The data were issued from the French multicenter cohort of renal transplant patients followed during 4 years (EPIGREN). The HRQoL of RTR was assessed five times (at 1, 3, 6, 9 and 12 months after transplantation) with the RTQ V2, a specific instrument consisting of 32 items describing five dimensions. Socio-demographic information, clinical characteristics and HRQoL (i.e., RTQ V2 and SF-36) were collected. For the five times, psychometric properties of the RTQ V2 were compared to those reported from the reference population assessed in the validation study.

RESULTS

Three hundred and thirty-four patients were enrolled. The proportions of well-projected items, item-internal consistency, item-discriminant validity, floor and ceiling effects, Cronbach's alpha coefficients and item goodness-of-fit statistics were satisfactory for each dimension at the five times of the study. The suitability indices of construct validity were higher than 90 % for each time (minimum-maximum: 90.8-97.4 %). The external validity was less satisfactory, with a suitability indices ranged from 46.7 % at M1 to 66.7 % at M12. However, the discrepancies with the reference population (mainly for the gender) appeared logical considering the scientific literature on HRQoL of RTR during the first post-transplant year and may not compromise the external validity.

CONCLUSION

These results support the validity and reliability of the RTQ V2 for evaluating HRQoL in RTR during the first post-transplant year, and confirm that the RTQ V2 is a useful tool to assess the HRQoL precociously after transplant.

The Role of Personality and Social Support in Health-Related Quality of Life in Chronic Kidney Disease Patients

BACKGROUND

Chronic kidney disease (CKD) is commonly associated with various negative health outcomes. The aim of this study was to examine the influence of personality and social support on health-related quality of life in patients with chronic kidney disease. Health-related quality of life (HRQoL) is the quality of life studied in relation to health, and it provides important information of patients' coping with their health issues.

METHOD

Participants comprised of 200 patients experiencing various stages of chronic kidney disease. All participants completed the Short-Form 36 (SF-36), Big Five Inventory (BFI) and the Medical Outcomes Study (MOS) Social Support questionnaires.

RESULTS

Participants consisted of 108 males (54.0%) and 92 females (46.0%) with the mean age of 59.3 years (SD 14.5). Results showed that higher levels of extraversion and lower perceived affectionate social support were associated with higher physical HRQoL, whereas higher levels of neuroticism were associated with poorer mental HRQoL.

CONCLUSION

The current study found that certain personality traits, namely extraversion and neuroticism, were found to be associated with HRQoL. In addition, affectionate social support was also associated with higher HRQoL. Therefore, special attention should be paid to the personality of CKD patients, as well as the type of social support that they have, in planning interventions to improve their health outcomes.

Perceived health after kidney transplantation: a cross-sectional comparison of long-term and short-term cohorts

Although increased longevity of grafts has led to a growing number of long-term kidney transplant recipients, knowledge about the perceived health of these patients remains limited. A cross-sectional sample of 609 patients (60% response) was stratified into a short-term (≤1 year), midterm (>1 and ≤8 years), and long-term cohort (>8 and ≤15 years posttransplantation). Cohorts were compared for perceived health (Visual Analogue Scale of the EQ-5D), number of symptoms, and number of comorbidities by analysis of variance/covariance and multivariate regression analyses. Long-term patients reported more symptoms, (F[2, 606] = 3.09, P = .046) and more comorbidities, (F[2, 588] = 4.75, P = .009) but similar levels of perceived health, (F[2, 550] = 2.37, P > .05). Furthermore, symptoms were less influential for perceived health among long- versus short-term (z = -2.08, P = .038) or midterm cohorts (z = -2.60, P = .009). Previously identified predictors of perceived health accounted for less variance in the long-term as opposed to short-term (z = 4.30, P < .001) and midterm cohort (z = 2.07, P = .039). Despite more symptoms and comorbidities, the perceived health of long-term kidney transplant recipients was comparable to the short- and midterm, possibly due to selective survival or patient adjustment. Because kidney function and symptoms were predominantly associated with short-term perceived health, there is an urgent need to identify variables associated with long-term perceived health.

Factors associated with health-related quality of life in renal transplant recipients: results of a national survey in France

Background

This study aims to identify factors associated with health related quality of life (HRQOL) through a comprehensive analysis of sociodemographic and clinical variables among a representative sample size of renal transplant recipients (RTR) in France.

Methods

A cross-sectional multicenter study was carried out in 2008. All RTR over 18 years old with a functioning graft for at least one year were included. Data included socio-demographic, health status, and treatment characteristics. To evaluate HRQOL, the Short Form-36 Health Survey (SF-36) and a HRQOL instrument for RTR (ReTransQol) were administered. Multivariate linear regression models were performed.

Results

A total of 1061 RTR were included, with a return rate of 72.5%. The variance explained in regression models of SF-36 ranges from 20% to 40% and from 9% to 33% for ReTransQol.

The variables which decreased scores of both HRQOL questionnaires were: females, unemployment, lower education, living alone, high BMI, diabetes, recent critical illness and hospitalization, non-compliance, a long duration of dialysis and treatment side effects.

Specific variables which decreased ReTransQol scores were dismissal and a recent surgery on the graft. These which decreased SF36 scores were being old and a recent infectious disease.

The variables the most predictors of worse HRQOL were: side effects, infectious disease, recent hospitalization and female gender.

Conclusions

The originality of our study’s findings was that novel variables, particularly treatment side effects and unemployment, have a negative effect on quality of life of RTR. The French Biomedicine Agency and the National Health Institute for Public Health Surveillance conduct specific actions for professional reintegration and therapeutic education programs in the national plan to improve the HRQOL of people living with chronic diseases.

Validation of the Dutch version of the transplant effects questionnaire in liver transplant recipients

Little is known about the extent to which transplant recipients face emotional problems with the receipt of a transplanted organ. The Transplant Effects Questionnaire (TxEQ) enables the quantification of these problems. This study evaluates the psychometric properties of the Dutch translation of the TxEQ (TxEQ-NL) in a group of liver transplant recipients. Confirmatory factor analyses of the TxEQ-NL revealed an adequate fit with the original version. However, four items showed factor loadings <.40. Internal consistency was acceptable (.66-.79). The small correlations between the TxEQ-NL and generic measures of psychological functioning indicated that the constructs measured are related but distinguishable. Therefore, the TxEQ-NL adds a new dimension to the measurement of psychological functioning of transplant recipients.

The perception of sleep quality in kidney transplant patients during the first year of transplantation

OBJECTIVE

Poor sleep quality is one of the factors that adversely affects patient quality of life after kidney transplantation, and sleep disorders represent a significant cardiovascular risk factor. The objective of this study was to investigate the prevalence of changes in sleep quality and their outcomes in kidney transplant recipients and analyze the variables affecting sleep quality in the first years after renal transplantation.

METHODS

Kidney transplant recipients were evaluated at two time points after a successful transplantation: between three and six months (Phase 1) and between 12 and 15 months (Phase 2). The following tools were used for assessment: the Pittsburgh Sleep Quality Index; the quality of life questionnaire Short-Form-36; the Hospital Anxiety and Depression scale; the Karnofsky scale; and assessments of social and demographic data. The prevalence of poor sleep was 36.7% in Phase 1 and 38.3% in Phase 2 of the study.

RESULTS

There were no significant differences between patients with and without changes in sleep quality between the two phases. We found no changes in sleep patterns throughout the study. Both the physical and mental health scores worsened from Phase 1 to Phase 2.

CONCLUSION

Sleep quality in kidney transplant recipients did not change during the first year after a successful renal transplantation.

Improving quality of life in patients with chronic kidney disease: influence of acceptance and personality

BACKGROUND

A low health-related quality of life (HQL) is associated with the evolution of chronic kidney disease (CKD) and mortality in patients in end-stage of the disease. Therefore research on psychological determinants of HQL is emerging. We investigate whether acceptance of the disease contributes to a better physical and mental health-related quality of life (PHQL and MHQL). We also examine the impact of personality characteristics on acceptance, PHQL and MHQL.

METHODS

In this cross-sectional study, patients from an outpatient clinic of nephrology completed self-report questionnaires on quality of life, acceptance and personality characteristics. We performed correlations, regression analyses and a path analysis.

RESULTS

Our sample of 99 patients had a mean duration of CKD of 10.81 years and a mean estimated Glomerular Filtration Rate (eGFR) by Modification of Diet in Renal Disease (MDRD)-formula of 34.49 ml/min (SD 21.66). Regression analyses revealed that acceptance had a significant positive contribution to the prediction of PHQL and MHQL. Neuroticism was negatively associated with acceptance and MHQL. Path analysis showed that 37% of the total effect of neuroticism on MHQL was mediated by acceptance.

CONCLUSIONS

Acceptance is an important positive variable in accounting for HQL, however, clinicians must be aware that if patients have a high level of neuroticism they are likely to have more difficulties with this coping strategy. These results provide a better understanding of psychological determinants of HQL in CKD, which can initiate another approach of these patients by nephrologists, specific psychological interventions, or other supporting public health services.

Personality influences quality-of-life assessments in adult patients after allogeneic hematopoietic SCT: results from a joint evaluation of the prospective German Multicenter Validation Trial and the Fred Hutchinson Cancer Research Center

The influence of personality on health related quality of life (QoL) and physical functioning in the setting of allogeneic hematopoietic SCT (alloHSCT) is unknown. We conducted a joint evaluation within two independent cohorts of alloHSCT recipients to investigate the impact of personality on reported QoL and physical functioning. Two-hundred-eight patients (median age 44 years, range 18-72) of cohort 1 and 93 patients (median age 55 years, range 19-79) of cohort 2 after alloHSCT were evaluated. Personality was assessed using the 24-adjective measure (AM), which measures the Big-Five personality domains and the Life Orientation Test-Revised (LOT-R), measuring optimism and pessimism. QoL was measured using the Functional Assessment of Cancer Therapy with bone marrow transplantation subscale (FACT-BMT), Short Form 36 (SF-36), the human activity profile (HAP), as well as the NIH criteria-based cGVHD activity assessment form and the Lee cGVHD symptom scale. Neuroticism was significantly associated with worse function measured by the HAP and FACT-BMT. Optimism significantly improved QoL captured by the FACT-BMT. Pessimism significantly impaired physical function captured by the HAP and SF-36. Extraversion was significantly associated with reduced depression and lower severity of cGVHD symptoms reported by the patient and the physician. The results suggest that personality traits and pre-treatment QoL assessments should be measured in clinical trials to facilitate the interpretation of QoL data.
