BackgroundPatients with chronic kidney disease (CKD) have a high symptoms burden that is related to a poor health-related quality of life (HRQoL) and high costs of care. Validated instruments may be useful for assessing the symptoms and monitoring outcomes in these patients. The Palliative care Outcome Scale-Symptoms Renal (POS-S Renal) is a patient-reported outcome measure for assessing symptoms in CKD stage 4–5. This study is the first cross-cultural adaptation and psychometric analysis of this clinical tool. The purpose of this study is to carry out a cross-cultural adaptation of the POS-S Renal for Spanish-speaking patients, and to perform an analysis of the psychometric properties of this questionnaire.MethodsThe English version of the POS-S Renal was culturally adapted and translated into Spanish using a double forward and backward method. An expert panel evaluated the content validity. The questionnaire was pilot-tested in 30 patients. A total of 200 patients with CKD stage 4–5 filled in a modified Spanish version of the POS-S Renal and the MSAS-SF. Statistical analysis to evaluate the psychometric properties of the questionnaire was carried out.ResultsThe content validity index (CVI) was 0.97, which indicated that the content of the instrument is an adequate reflection of the symptoms in advanced CKD (ACKD). The factor analysis indicated a two-factor solution explaining 35.05% of total variance. The confirmatory factor analysis (CFA) demonstrated that the two factor model was well supported (comparative fit index = 0.98, root mean square error of approximation = 0.068). This assessment tool demonstrated a satisfactory test–retest reliability (r = 0.909 to factor 1, r = 0.695 to factor 2, r = 0.887 to total score), good internal consistency to factor 1 (α = 0.78) and moderate internal consistency to factor 2 (α = 0.56). Concurrent criterion-related validity with MSAS-SF was also demonstrated, with r = 0.860, which indicated a high degree of correlation with a validated instrument that has been used in patients with ACKD.ConclusionsThe Spanish modified version of the POS-S Renal is a reliable and valid instrument that can be used to assess symptoms in Spanish patients with CKD stage 4–5.Electronic supplementary materialThe online version of this article (doi:10.1186/s12882-016-0402-8) contains supplementary material, which is available to authorized users.

Patients with chronic kidney disease (CKD) Stage 5, experience multiple symptoms that negatively affect the health-related quality of life (HRQoL). This study examined the cluster of symptoms and their association with disease severity and comorbidities. The study sample included 123 patients with CKD Stage 5; 60 patients were in the dialysis group and 63 patients in the Conservative Kidney Management group. Symptom data were collected using the Spanish modified version of Palliative Care Outcome Scale-Symptoms (POS-S) Renal, a validated questionnaire to assess symptoms in this population. More than half of the patients described weakness, difficulty sleeping, and feeling depressed. Two symptom clusters were identified. There was no significant statistical correlation between disease severity and symptoms and between comorbidities and symptoms. The tendency of these symptoms to occur together has implications for improving symptom management in this population. Routine symptom assessment can be useful in clinical and research settings.

Many instruments have been developed to assess the quality of dying and death. The Quality of Dying and Death Questionnaire is the best available measure of the quality of dying and death. It is the only questionnaire identified in this review where all psychometric properties according to the COSMIN checklist have been evaluated.

Introduction One of the most widely used instruments to identify symptoms that may be related to central sensitization is the Central Sensitization Inventory (CSI). Although this instrument has been translated and validated in Spanish patients with chronic musculoskeletal pain, no psychometric analysis has been carried out in breast cancer survivors. The aim of this study was to perform a psychometric analysis of the Spanish version of the Central Sensitization Inventory (CSI‐Sp) in Spanish breast cancer survivors. Materials and Methods A validation study was carried out in 183 breast cancer survivors. A psychometric analysis of internal consistency, factor structure, and test‐retest reliability of the CSI‐Sp was performed. Internal consistency was determined using Cronbach’s alpha. Test‐retest reliability was evaluated using the Intraclass Correlation Coefficient (ICC) Type 2.1. Exploratory factor analysis was used to determine the internal structure of the questionnaire. Results The internal consistency was high (α = 0.91). The test‐retest reliability was satisfactory with excellent values (ICC 2.1 = 0.95). The exploratory factor analysis yielded a one factor structure explaining the 33.88% of total variance. Conclusions The CSI‐Sp has demonstrated to be a psychometrically strong measure for assessing central sensitization symptoms in breast cancer survivors based on internal consistency, test‐retest reliability, and structural validity. Further studies that analyze other measurement properties in different Spanish clinical populations are needed.
