Exploring the relationships between health status, illness perceptions, coping strategies and psychological morbidity in a chronic kidney disease cohort

Coping strategies and its relationship with sexual dysfunction in adults receiving haemodialysis and peritoneal dialysis: A cross-sectional study

AIM

To explore relationship coping strategies and sexual dysfunction, and the predictive factors of sexual dysfunction in adults receiving haemodialysis and peritoneal dialysis.

BACKGROUND

Sexual dysfunction is a common problem in adults receiving haemodialysis and peritoneal dialysis. This problem may be related to psychological and physiological conditions. However, the association between psychological conditions such as coping strategies and sexual dysfunction is not clearly understood.

DESIGN

This study is a cross-sectional study.

METHODS

The data were collected from November 2021 to July 2022 using the General Information Form, Arizona Sexual Experiences Scale: Female and Male Versions, and the Ways of Coping Inventory. Correlation and multiple regression analyses were conducted to investigate the relationship between coping strategies and sexual dysfunction.

REPORTING METHOD

STROBE checklist.

RESULTS

A total of 110 adults, 67 on haemodialysis and 43 on peritoneal dialysis, who met the eligibility criteria were included in this study. The optimistic, helpless and submissive approach sub-dimensions of coping strategies had positive correlation with sexual dysfunction in adults receiving haemodialysis. Among the sub-dimensions of the ways of coping inventory, helpless approach was positive predictor and seeking social support was negative predictor of sexual dysfunction in adults receiving haemodialysis. The coping strategies were not predictors of sexual dysfunction for adults receiving peritoneal dialysis.

CONCLUSIONS

This study showed that helpless coping strategy increases sexual dysfunction, and seeking social support decreases sexual dysfunction in haemodialysis.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

According to this study, social support is effective coping strategy for reducing sexual dysfunction. Education and support for effective coping strategies should be provided to dialysis patients by healthcare professionals at the start of dialysis treatment. Effective coping strategies should be integrated into routine care standards and nursing or hospital policies.

PATIENT OR PUBLIC CONTRIBUTION

Adults receiving haemodialysis and peritoneal dialysis were involved in this study.

Patient activation and psychological coping strategies to manage challenging circumstances during the COVID-19 pandemic in people with kidney disease

BACKGROUND

Coping with health problems requires some degree of self-management; however, an individual's ability to self-manage can be threatened during challenging times, such as the COVID-19 pandemic. Exploring differences and changes in psychological well-being and coping strategies between those with low and high patient activation may inform appropriate interventions to support psychological coping.

METHODS

People with chronic kidney disease (CKD) (non-dialysis and transplant) were recruited from 11 hospital sites across England between August and December 2020. Participants responded to an online survey study, including the Brief Coping Orientation to Problem Experienced (COPE) Inventory, Depression, Anxiety and Stress Scale (DASS-21), Short Health Anxiety Index (SHAI), and Patient Activation Measure (PAM-13). A follow-up survey was conducted 6-9 months later. Paired t tests assessed within-group changes, and chi-squared tests compared coping strategies utilised by low- and high-activated participants. General linear modelling was performed to determine the relationship between patient activation and coping strategies, and covariates.

RESULTS

Two hundred and fourteen participants were recruited (mean age: 60.7, 51% male, mean eGFR: 38.9 ml/min/1.73 m2). Low-activated participants were significantly more anxious than high-activated participants (P = 0.045). Health anxiety significantly decreased (i.e., got better) for high-activated participants (P = 0.016). Higher patient activation scores were associated with greater use of problem-focused strategies (β = 0.288, P < 0.001). Age (β = - 0.174, P = 0.012), sex (β = 0.188, P = 0.004), and education level (β = 0.159, P = 0.019) significantly predicted use of problem-focused strategies.

DISCUSSION

Those with higher activation had lower levels of anxiety, and more frequently used adaptive coping strategies during the pandemic. Targeted support and interventions may be required for people with CKD to enhance patient activation, encourage more positive adaptive coping strategies, and mitigate maladaptive coping strategies.

Impact of chronic kidney disease on illness perceptions, coping, self-efficacy, psychological distress and quality of life

Chronic kidney disease (CKD) negatively impacts psychological well-being and quality of life (QoL). Underpinned by the Common Sense Model (CSM), this study evaluated the potential mediating role of self-efficacy, coping styles and psychological distress on the relationship between illness perceptions and QoL in patients living with CKD. Participants were 147 people with stage 3-5 kidney disease. Measures included eGFR, illness perceptions, coping styles, psychological distress, self-efficacy and QoL. Correlational analyses were performed, followed by regression modelling. Poorer QoL was associated with greater distress, engagement in maladaptive coping, poorer illness perceptions and lower self-efficacy. Regression analysis revealed that illness perceptions predicted QoL, with psychological distress acting as a mediator. The proportion of variance explained was 63.8%. These findings suggest that psychological interventions are likely to enhance QoL in CKD, if they target the mediating psychological processes associated with illness perceptions and psychological distress.

Association between Depressive Symptom Trajectory and Chronic Kidney Disease Progression: Findings from the Chronic Renal Insufficiency Cohort Study

Key Points

Depressive symptoms are largely stable over time among individuals with mild-to-moderate CKD Low educational attainment, cigarette smoking, and poor quality of life are associated with persistent depressive symptoms Persistent depressive symptoms are associated with nonlinear and rapid decline in kidney function

Background

Although depression is highly prevalent among individuals with CKD, little is known about the course of depressive symptoms over time. We characterized trajectories of depressive symptoms and CKD progression and evaluated the association between depressive symptoms trajectory and CKD progression.

Methods

Two thousand three hundred sixty-one individuals with mild-to-moderate CKD enrolled in the Chronic Renal Insufficiency Cohort Study were analyzed. The Beck Depression Inventory (BDI) was used to assess depressive symptoms at baseline and biennially. Higher BDI scores indicate worse depressive symptoms. eGFR was calculated using the 2021 CKD-EPI equation. Group-based trajectory models were used to determine trajectories of BDI score and eGFR change over time. Multinomial logistic regression was used to examine factors associated with BDI trajectories and to evaluate the association of BDI trajectories with eGFR change.

Results

Over 8 years of follow-up, three patterns of depressive symptoms were identified: persistently low BDI score (57.7%), persistently moderate BDI score (33.1%), and persistently high BDI score (9.2%). Three eGFR trajectory groups were identified: nonlinear, rapid eGFR decline (21.5%); linear, expected eGFR decline (54.8%); and stable eGFR (23.7%). Predictors of persistently moderate and high BDI trajectories included low educational attainment, smoking, and poor quality of life. Compared with those with a persistently low BDI score, the odds for nonlinear, rapid eGFR decline were higher for those with persistently moderate BDI scores (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.04 to 2.03) and persistently high BDI scores (OR, 1.90; 95% CI, 1.02 to 3.56). No association between moderate BDI score and linear, expected eGFR decline was observed.

Conclusions

Depressive symptoms remained largely stable among individuals with mild-to-moderate CKD, and persistently moderate and high BDI scores were associated with nonlinear, rapid eGFR decline. Future work is needed to better understand the interplay between depression and CKD progression.

Lifestyle and chronic kidney disease: A machine learning modeling study

Background

Individual lifestyle varies in the real world, and the comparative efficacy of lifestyles to preserve renal function remains indeterminate. We aimed to systematically compare the effects of lifestyles on chronic kidney disease (CKD) incidence, and establish a lifestyle scoring system for CKD risk identification.

Methods

Using the data of the UK Biobank cohort, we included 470,778 participants who were free of CKD at the baseline. We harnessed the light gradient boosting machine algorithm to rank the importance of 37 lifestyle factors (such as dietary patterns, physical activity (PA), sleep, psychological health, smoking, and alcohol) on the risk of CKD. The lifestyle score was calculated by a combination of machine learning and the Cox proportional-hazards model. A CKD event was defined as an estimated glomerular filtration rate <60 ml/min/1.73 m², mortality and hospitalization due to chronic renal failure, and self-reported chronic renal failure, initiated renal replacement therapy.

Results

During a median of the 11-year follow-up, 13,555 participants developed the CKD event. Bread, walking time, moderate activity, and vigorous activity ranked as the top four risk factors of CKD. A healthy lifestyle mainly consisted of whole grain bread, walking, moderate physical activity, oat cereal, and muesli, which have scored 12, 12, 10, 7, and 7, respectively. An unhealthy lifestyle mainly included white bread, tea >4 cups/day, biscuit cereal, low drink temperature, and processed meat, which have scored −12, −9, −7, −4, and −3, respectively. In restricted cubic spline regression analysis, a higher lifestyle score was associated with a lower risk of CKD event (p for linear relation < 0.001). Compared to participants with the lifestyle score < 0, participants scoring 0–20, 20–40, 40–60, and >60 exhibited 25, 42, 55, and 70% lower risk of CKD event, respectively. The C-statistic of the age-adjusted lifestyle score for predicting CKD events was 0.710 (0.703–0.718).

Conclusion

A lifestyle scoring system for CKD prevention was established. Based on the system, individuals could flexibly choose healthy lifestyles and avoid unhealthy lifestyles to prevent CKD.

Depression and Associated Factors in Chinese Patients With Chronic Kidney Disease Without Dialysis: A Cross-Sectional Study

Background: Chronic kidney disease (CKD) has been a globally public health problem over the past decades. The maintenance of physical and mental health is of importance for patients nowadays. Notably, depression is prevalent and associated with various adverse events in CKD patients without dialysis. Prior studies have reported that pain, negative illness perception, pain, and low self-esteem are potential risk factors of depression, while few studies have comprehensively investigated the mechanisms among these factors and depression among this population.

Purpose: This study aims to investigate the prevalence of depression and further explore the factors associated with depression among CKD patients without dialysis in China.

Design and Methods: We conducted a cross-sectional study in patients with diagnosed CKD to investigate the prevalence of depression was by the Beck Depression Inventory-II (BDI-II). The data on pain interference, illness perception, and self-esteem were also collected via self-administered questionnaires. A structural equation model (SEM) was used to examine the factors associated with depression.

Main Findings: From June to October 2019, we successfully interviewed 334 CKD patients at the outpatient clinics. Their mean age was 45.6 years (ranging from 19 to 74 years), and 48.5% were male. Most respondents were at early CKD stages (77.5% stage 1–3) and the prevalence of depression was 22.2%. We found a moderate association between illness perception and depression, which was modified by self-esteem. Similar but weaker association was found between pain interference and depression.

Conclusion and Recommendations: Negative illness perception, low self-esteem and severe pain interference were associated with depression among Chinese CKD patients without dialysis. Future studies are warranted to investigate the underlying mechanism and formulate the intervention strategies for this high-risk population.

Illness perceptions predict distress in patients with chronic kidney disease

BACKGROUND

Patients diagnosed with chronic kidney disease (CKD) report increased distress associated with their clinical diagnosis. Distress in patients with predialysis CKD, has been linked to several adverse events; including increased risk of hospitalisation, early dialysis initiation and even death, suggesting that distress is a matter of great concern during routine care in predialysis CKD.

AIMS

The present study aimed to assess the nature of illness perceptions and the level of distress in a CKD cohort diagnosed with different stages of kidney disease. It also aimed to explore the correlates of distress and to create a model for distress and its associated predictors making use of hierarchical regression analysis.

METHODS

A sample of 200 patients diagnosed with Chronic Kidney Disease were recruited for this study from the nephrology outpatient clinics of Mater Dei Hospital, Malta. The participants were assessed for their; illness perceptions, treatment beliefs, level of depression and anxiety, coping style, as well as treatment adherence. Routine clinical information was also collected for participants, including a co-morbidity score.

RESULTS

A percentage of 33.5% of the participants reported moderate distress, whilst 9.5% reported severe distress. Stronger illness identity, a perception of timeline as being increasingly chronic or cyclical in nature, greater consequences and higher emotional representations were associated with more advanced stages of CKD. In contrast, lower personal and treatment control and poorer illness coherence were associated with more advanced stages of CKD. Results from the hierarchical regression analysis showed that illness perceptions contributed significantly to distress over and above the clinical kidney factors. Being female, having low haemoglobin and specific illness perceptions including; perceptions of greater symptomatology, longer timeline, low personal control and strong emotional representations, as well as resorting to maladaptive coping, were all significantly associated with distress symptoms. Nevertheless, illness perceptions accounted for the greatest variance in distress thus indicating that the contribution of illness perceptions is greater than that made by the other known covariates.

CONCLUSION

Illness perceptions hold a principal role in explaining distress in CKD, relative to other traditional covariates. For this reason, illness perceptions should be addressed as a primary modifiable component in the development of distress in CKD.

Illness perception in patients with chronic kidney disease and kidney failure: a scoping review protocol

INTRODUCTION

Patient education is a crucial component in the management of chronic kidney disease (CKD); however, many education programmes do not tailor to patients' disease-related belief and emotional reactions. According to Leventhal's self-regulation model, such beliefs and reactions, known as illness perceptions, are a part of patients' understanding of their disease and treatment-related actions. The existing research of illness perception in the field of nephrology has been heterogenous in terms of study outcomes and in study population; and the evidence of how illness perceptions affect behavioural and decisional outcomes is limited. This scoping review aims to map and summarise the evidence of published literature on illness perception among patients with CKD not yet treated by dialysis and kidney failure.

METHODS AND ANALYSIS

This study bases its approach on Joanna Brigg's Institute Guidelines on scoping review methods. The search strategy was developed together with a medical information specialist. Searches will be performed on acceptance of publication in the following databases: PubMed, EMBASE, PsycINFO via Ovid, Scopus and the Cumulative Index to Nursing and Allied Health Literature. Searches will be run without incorporating a date restriction in order to capture content from the databases' inception to present day. Search terms including 'illness perception', 'kidney disease' and 'kidney failure' will be screened in titles and abstracts. Two independent researchers will screen the abstracts and full text for full eligibility. We will include studies focusing on illness perception of patients with CKD with estimated glomerular filtration rate <60 mL/min/1.73 m2, kidney failure or recipients of kidney transplant. We will exclude patients <18 years of age, patients with acute kidney injury and non-English articles. All demographic data, study design and study findings will be collected and analysed using a data abstraction tool.

ETHICS AND DISSEMINATION

This study does not require internal review board approval. We will present the findings of this scoping review in a peer-reviewed journal.

A psychosocial intervention for individuals with advanced chronic kidney disease: A feasibility randomized controlled trial

AIM

The current study evaluated the feasibility and preliminary efficacy of a psychosocial intervention, the Kidney Optimal Health Program, in reducing symptoms of depression and anxiety in individuals with advanced chronic kidney disease.

METHODS

Patients with stage 4 or 5 chronic kidney disease were randomized to either a nine-session psychosocial intervention programme or usual care. Feasibility was assessed through recruitment and retention rates and programme acceptability. Participants completed assessments of depression, anxiety and psychosocial health at baseline and at 3-, 6- and 12-month follow-up. A repeated-measures analysis of variance was used to compare groups on outcomes over time.

RESULTS

One hundred and twenty-eight patients were screened for eligibility; 84 consented to participant and were randomized to receive the intervention (N = 42) or usual care (N = 42). 27 (32.1%) participants withdrew prior to baseline assessment. Of those who completed the baseline assessment (N = 57), trial retention was high (75.4% at 3-month, 80.7% at 6-month and 70.2% at 12-month follow-up). Participants reported high levels of programme acceptability. The patients who completed the intervention (N = 17) demonstrated significantly decreased depression at 12-month follow-up compared to the usual care group (N = 13).

CONCLUSION

The results support the feasibility of the Kidney Optimal Health Program intervention in recruitment, retention and programme acceptability with an improved screening protocol. Preliminary support is provided for improvement in depressive symptoms in patients with advanced chronic kidney disease. Further investigation through a fully powered randomized controlled trial is warranted.

Psychometric Properties of the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) in the Iranian Older Adults

PURPOSE

Mental wellbeing is considered as an important and effective factor in older adults' psychological health. Due to lack of a standard instrument for the assessment of mental wellbeing in Iranian older adults, the present study was performed to examine validity and reliability of the Persian version of the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS-P) for use among Iranian older adults.

PATIENTS AND METHODS

The study sample included 304 older adults aged 60 and over, admitted to the Shohada Educational Hospital affiliated to the Tabriz University of Medical Sciences, North West of Iran. The participants were recruited through the convenience sampling method in May to September 2017.

RESULTS

The mean and standard deviation of the mental wellbeing score were 50.30 and 8.82, respectively. Exploratory factor analysis (EFA) results demonstrated a one-factor solution with 13 items which was verified by the confirmatory factor analysis (CFA). The estimated internal consistency measure of Cronbach's alpha (0.93) and two weeks' time test-retest reliability index (0.84) met the prerequisite criteria.

CONCLUSION

According to the results, the WEMWBS-P with 13 items has acceptable validity and reliability to assess the mental wellbeing of Iranian and other Persian-speaking older adults.

Illness perceptions in adolescents with chronic fatigue syndrome and other physical health conditions: Application of the common sense model

BACKGROUND

The common sense model (CSM) proposes that illness perceptions guide coping and illness management, which subsequently affects outcomes. Chronic fatigue syndrome (CFS) is associated with severe functional impairment. CFS is distinct from other physical health conditions in that individuals can experience high levels of uncertainty, stigma and disbelief from others. This study aimed to compare illness perceptions in adolescents with CFS with other physical health conditions, using a cross-sectional, between-groups design.

METHODS

Adolescents (aged 11-18) with CFS (n = 49), type 1 diabetes (n = 52) and juvenile idiopathic arthritis (n = 42) were recruited through National Health Service (NHS) clinics and online, and completed a series of questionnaires.

RESULTS

Adolescents with CFS differed on the perceived consequences, timeline, personal control, treatment control, identity and understanding dimensions of illness perceptions. Except for identity, these dimensions were predicted by health condition even when accounting for age, gender, fatigue, physical functioning, anxiety and depression.

CONCLUSIONS

Results offer preliminary evidence for the applicability of the CSM in adolescents, with implications for supporting adolescents with physical health conditions. Results suggest that psychological interventions targeting perceived control, understanding and identity may have particular utility for adolescents with CFS.

A Qualitative Pilot Study of the Perceptions in Older Adults with End-Stage Kidney Disease on Hemodialysis

BACKGROUND

Little is known about the perceptions of older adults with end-stage kidney disease (ESKD) on chronic hemodialysis (HD) even though this could potentially influence how treatment is received. This study explores the perceptions of older adults with ESKD on HD, specifically their decision to initiate HD, preconceptions and expectations of HD, perceived difficulties with HD, and coping strategies.

DESIGN

Cross-sectional.

SETTING

Outpatient chronic dialysis units.

PARTICIPANTS

Older adults with ESKD on HD.

INTERVENTION

Open-ended interviews were conducted with 15 participants. Inclusion criteria were age 60 years and older, HD duration of at least three months, and ability to consent and participate in the interview process.

RESULTS

We report on four identified domains: decision to initiate HD; preconceptions and expectations of HD; drawback of HD; and coping strategies. All participants were reluctant to initiate HD, but made the decision on advice from their physicians for varying reasons. Trust in physicians' opinions also played a role for some. Some participants had positive preconceptions of HD, while a few had negative preconceptions or unrealistic expectations. Even though the majority of participants identified several difficulties with being on HD, they also had positive coping strategies, and the majority indicated that they would make the same decision to initiate HD.

CONCLUSION

As clinicians are turning more to patient-centered medicine, understanding patients' perceptions of HD is of crucial importance. Our study highlights the importance of improving pre-hemodialysis education to ensure that patients' expectations are realistic, as well as identifying individualized coping strategies by patients.

Self-awareness and the evaluation of hot flash severity: observations from the Seattle Midlife Women's Health Study

OBJECTIVE

The purpose of this study was to test the association of two dimensions of self-awareness with hot flash (HF) severity.

METHODS

A subset of women from the Seattle Midlife Women's Health Study (N = 232) provided data for these analyses. Structural equation modeling was used to evaluate two dimensions of self-awareness (Internal States Awareness [ISA] and Self-Reflectiveness [SR]), and secondary factors of perceived stress, anxiety, and attitudes toward menopause as continuous with earlier life, health perceptions, and menopausal stage with respect to HF severity. The measurement and structural models were tested with a maximum likelihood missing values estimator and displayed good model fit.

RESULTS

Women with greater ISA reported greater HF severity (β = 0.17, P < 0.05). In addition, women in later menopausal transition stages reported greater HF severity and those with attitudes of continuity toward menopause reported less severe HFs (β = 0.20, P < 0.01, β = -0.30, P < 0.001, respectively). SR was not related to HF severity. Women with higher levels of SR reported greater perceived stress levels (β = .51, P < 0.001), and those with greater perceived stress reported greater anxiety levels (β = 0.63, P < 0.001) and attitudes of continuity toward menopause as less continuous with earlier life (β = -0.30, P < 0.001).

CONCLUSIONS

ISA (balanced self-awareness) was associated with greater HF severity, suggesting that enhanced balanced self-awareness may promote women's ability to evaluate their symptom experience. A multidimensional construct of self-awareness, perceived stress, anxiety, and attitude toward menopause are all plausible targets for future intervention studies of symptom management.

Exploring the relationship between illness perceptions and depression in patients with chronic kidney disease: A systematic literature review

BACKGROUND

The prevalence of depression is found to increase from early stages to later stages of chronic kidney disease. Research on illness perceptions in patients undergoing dialysis has confirmed that patients' beliefs are associated with important outcomes; one of the most significant being depression. However, the association between illness perceptions and depression in patients in pre-dialysis care remains unclear.

OBJECTIVE

The main objective of this systematic review was to explore the associative relationship between illness perceptions and depression in patients with CKD prior to the commencement of dialysis.

METHODS

The inclusion criteria for papers in this review were studies investigating illness perceptions and depression in patients diagnosed with CKD. Eligible studies were identified by searching the following electronic databases; Medline, CENTRAL, Embase, Psych INFO, Web of Science and Scopus. Data on the participants and the severity of kidney disease, illness perceptions and depression were extracted.

RESULTS

Sixty-four studies met the criteria for full text review and of these, only four studies met the inclusion criteria following data extraction and quality assessment. Consistent with the common sense model, disease severity was found to be significantly associated with illness perceptions, and both were found to be associated with depression CONCLUSIONS: The results from this review provide further evidence that the illness perceptions and disease severity play a crucial role in the adaption to CKD. This review highlights the lack of research in this area and concludes that more studies are needed to determine the nature and impact of illness perceptions in relation to depression in pre-dialysis CKD.

Anxiety and depression in patients with end-stage renal disease: impact and management challenges - a narrative review

Psychiatric disorders commonly co-exist with the diagnosis of chronic kidney disease (CKD). Research on depression and CKD has increased to a great extent. Multiple studies have demonstrated that depression is more prevalent in CKD and that end-stage renal disease is a robust risk factor for adverse outcomes such as hospitalization and mortality, yet these are often underdiagnosed or untreated. This review provides a selective overview on the prevalence rates of depression and anxiety in patients with CKD and across renal replacement therapies, the factors most consistently associated with symptoms of distress and their clinical implications. Finally, treatment and management strategies from relevant literature are appraised and discussed.

Illness beliefs among patients with chronic widespread pain - associations with self-reported health status, anxiety and depressive symptoms and impact of pain

Background

Chronic widespread pain (CWP) is a disabling condition associated with a decrease in health. Illness beliefs are individual and are acquired during life. Constraining beliefs may prevent patients from regaining health. Understanding these patients’ illness beliefs may be a way to improve the health care they are offered. The aim of this study was to describe illness beliefs among patients with CWP and associations with self-reported health, anxiety and depressive symptoms, and impact of pain.

Method

In this cross-sectional study, questionnaires were sent by mail to 330 patients including socio-demographic information, the Illness Perception Questionnaire (IPQ-R), the Short-Form General Health Survey (SF-36) and the Hospital Anxiety and Depression Scale (HADS). Data were analysed using descriptive statistics, non-parametric tests and linear regression analyses.

Results

Patients experienced and related a high number of symptoms to CWP (mean (SD) 9 (3)). The patients believed their illness to be long lasting, to affect their emotional well being, and to have negative consequences for their lives. Some 72% reported having severe or very severe pain, and impact of pain according to SF-36 was negatively correlated to several illness beliefs dimensions, anxiety- and depressive symptoms. In regression analyses, the Identity, Consequences and Personal control dimensions of IPQ-R and Anxiety- and Depressive symptoms explained 32.6–56.1% of the variance in the two component scores of SF-36.

Conclusion

Constraining illness beliefs in patients with CWP are related to worse health status, especially in cases of high number of physical or mental symptoms, beliefs of negative consequences or the illness affecting them emotionally. Identification and understanding of these beliefs may reduce patients’ suffering if they are taken into consideration in rehabilitation programs and in development of new evidence-based interventions aimed at increasing health in patients with CWP.

Reliability and validity of the coping strategy inventory-short form applied to hemodialysis patients in 13 countries: Results from the Dialysis Outcomes and Practice Patterns Study (DOPPS)

OBJECTIVES

The Coping Strategies Inventory-Short Form (CSI-SF) measures four coping strategies based on 16 items: 4 items each indicating problem- vs. emotion-focused engagement or disengagement. Here we provide the first assessment of reliability and construct validity of the CSI-SF among hemodialysis patients across 13 countries.

METHODS

The CSI-SF was completed by patients in 9 languages in phase 4 of the Dialysis Outcomes and Practice Patterns Study (2009-11). Cronbach's alpha was used to assess internal consistency. Exploratory and confirmatory factor analyses were applied to assess the factor structure of the CSI-SF by country and language. CSI-SF data were analyzed from 7201 patients (60% male; median age 62.5 [range 18-96] years).

RESULTS

Good internal consistency (α=0.56-0.80) was seen for three scales in English (US, UK, Canada, Australia, New Zealand), German, and Swedish versions. The fourth scale was internally consistent if two items were dropped. In these countries, both exploratory and confirmatory factor analyses indicated a factor structure consistent with the four CSI-SF scales. Other language versions showed a factor structure inconsistent with these four scales.

CONCLUSION

The slightly modified English, German, and Swedish versions of the CSI-SF are reliable and valid instruments for measuring coping strategies in hemodialysis patients.

Design and protocol for the Dialysis Optimal Health Program (DOHP) randomised controlled trial

Background

Chronic kidney disease (CKD) and end-stage kidney disease (ESKD) are serious and growing health problems with enormous impact on psychological and social functioning. Despite high rates of comorbid depression and anxiety in these patient populations, and the adverse impact these have upon treatment adherence, quality of life, social connectedness and healthcare costs there has been little attention focused on the prevention or management of these problems. Thus, our aim was to evaluate the Dialysis Optimal Health Program (DOHP) that adopts a person-centred approach and engages collaborative therapy to educate and support those diagnosed with ESKD who are commencing dialysis.

Methods

The study design is a randomised controlled trial. Ninety-six adult patients initiating haemodialysis or peritoneal dialysis will be randomly allocated to either the intervention (DOHP) or usual care group. Participants receiving the intervention will receive nine (8 + 1 booster session) sequential sessions based on a structured information/workbook, psychosocial and educational supports and skills building. The primary outcome measures are depression and anxiety (assessed by the Hospital Anxiety and Depression Scale; HADS). Secondary outcomes include health-related quality of life (assessed by the Kidney Disease Quality of Life instrument; KDQOL), self-efficacy (assessed by General Self-Efficacy Scale) and clinical indices (e.g. albumin and haemoglobin levels). Cost-effectiveness analysis and process evaluation will also be performed to assess the economic value and efficacy of the DOHP. Primary and secondary measures will be collected at baseline and at 3-, 6-, and 12-month follow-up time points.

Discussion

We believe that this innovative trial will enhance knowledge of interventions aimed at supporting patients in the process of starting dialysis, and will broaden the focus from physical symptoms to include psychosocial factors such as depression, anxiety, self-efficacy, wellbeing and community support. The outcomes associated with this study are significant in terms of enhancing an at-risk population’s psychosocial health and reducing treatment-related costs and associated pressures on the healthcare system.

Patient's perceptions of chronic kidney disease and their association with psychosocial and clinical outcomes: a narrative review

Patients with chronic kidney disease (CKD) form organized beliefs regarding their illness and treatment. These perceptions influence the coping strategies employed by an individual to manage his/her illness and may act as a predictor for his/her willingness to engage in self-management behaviours. While illness perceptions have been identified as predictors of non-adherence, depression and mortality in dialysis patients, there is a paucity of research in CKD patients not requiring renal replacement therapy. This narrative review synthesizes the existing literature regarding the role of illness perceptions and associated clinical and psychosocial outcomes in non-dialysis CKD patients. Studies were identified following database searches of AMED, BNI, CINAHL, EMBASE, Health Business Elite, HMIC, Medline, PsycINFO and Google Scholar in January 2016. Despite the small evidence base, existing studies indicate that negative illness perceptions are associated with disease progression and a number of psychosocial outcomes in non-dialysis CKD patients. Evidence from other clinical populations suggests that illness perceptions are modifiable through psychological intervention, which may be most effective if delivered early before beliefs have the chance to become more established. Therefore, targeting illness perceptions in the earlier stages of CKD may be optimal. Further studies are now required to ascertain the mechanisms through which illness perceptions predict psychosocial and clinical outcomes in CKD patients and to ultimately test the efficacy of illness perception–based interventions.
