International psychometric validation of the Living with Chronic Illness Scale in Spanish-speaking patients with chronic obstructive pulmonary disease.

ABSTRACT:

Objectives

To validate the Living with Chronic Illness (LW-CI) Scale in patients with chronic obstructive pulmonary disease (COPD).

Design

Observational, cross-sectional validation study with retest. Acceptability, reliability, precision and construct validity were tested.

Setting

The study took place in primary and secondary specialised units of public and private hospitals of Spain and Colombia.

Participants

The study included 612 patients with COPD assessed from May 2018 to May 2019. A consecutive cases sampling was done. Inclusion criteria included: (A) patients with a diagnosis of COPD; (B) native Spanish speaking; (C) able to read and understand questionnaires; and (D) able to provide informed consent. Exclusion criteria included: (A) cognitive deterioration and (B) pharmacological effect or disorder that could disrupt the assessment.

Results

The LW-CI-COPD presented satisfactory data quality, with no missing data or floor/ceiling effects, showing high internal consistency for all the domains (Cronbach's alpha for the total score 0.92). Test-retest reliability was satisfactory (intraclass correlation coefficient=0.92). The LW-CI-COPD correlated 0.52-0.64 with quality of life and social support measures. The scale demonstrated satisfactory known-groups validity, yielding signiﬁcantly different scores in patients grouped according to COPD severity levels.

Conclusions

This has been the first validation study of the LW-CI-COPD. It is a feasible, reliable, valid and precise self-reported scale to measure living with COPD in the Spanish-speaking population. Therefore, it could be recommended for research and clinical practice to measure this concept and evaluate the impact of centred-care interdisciplinary interventions based on the patients' perspective, focused on providing holistic and comprehensive care to patients with COPD.

Project description:BackgroundRheumatoid arthritis (RA) knowledge has been constructed with studies performed in Caucasians patients; Latin American patients present unique characteristics. Empowerment is a social multidimensional construct that has been associated to better health-related quality of life in RA. There is no validated instrument for use with Spanish-speaking patients. The objective of the study was to adapt the Spanish version of the Health Empowerment Scale (S-HES), which was selected for its psychometric properties and suitability for low-literacy populations, for RA Hispanic patients (RAEH), and to perform its psychometric validation.MethodsRAEH adaptation, pilot testing, and psychometric validation were performed. Three convenience samples of RA outpatients from a national tertiary care level center were used. For RAEH adaptation, the word "health" was substituted with "RA" in the original S-HES, integrated by 8 items. Pilot testing (in 50 patients) assessed feasibility. Psychometric validation included content validity (nine experts rated item convenience, clarity, and cultural semantic accuracy), internal consistency (in 200 patients, Cronbach's alpha) and test-retest (in a subsample of 50 patients, ICC and 95% CI), construct validity (factor analysis), and face validity (in 20 patients, % of agreement). Patients gave written informed consent.ResultsPatients were primarily middle-aged females and had typical long-standing disease, although early disease was represented. In the psychometric validation sample, the majority of the outpatients had autoantibodies; meanwhile, half of them had no evidence of disease activity, with acute reactants phase determinations within normal range. Patients with comorbidities and joint replacement were also included. Experts agreed upon the attributes of content validity: 83-100% considered the item was essential, 100% agreed on the item's clarity and 80-100% on the cultural semantic accuracy. In the pilot sample, ? 80% of the patients agreed with the item's clarity and format. In the psychometric validation sample, mean RAEH was 34 (maximum possible score: 40?=?highest score). RAEH had a good internal consistency, Cronbach's ??=?0.86, and moderately good reliability (ICC [95% CI] test-retest: 0.79 [0.62-0.88]). Factor analysis for construct validity showed a single factor explaining 52% of the variance. Patients agreed with each item content validity (85-100%) and clarity (75-100%).ConclusionsRAEH was valid and reliable to evaluate empowerment in Spanish-speaking RA patients.

Project description:The 20-item Pain Anxiety Symptom Scale (PASS-20) was adapted for Spanish-speaking Mexican Americans who report chronic pain (SSMACP). The instrument measures pain-related anxiety with fear, physiological, avoidance/escape, and cognitive anxiety as subtypes. In SSMACP, the Spanish PASS-20's psychometric properties were evaluated while exploring relationships between pain-related anxiety with other variables. Using convenience sampling, 188 SSMACP (women = 108, men = 77; mean age = 37.20 years, standard deviation = 9.87) were recruited across the United States. Confirmatory factor analyses examined the structural validity of the hierarchical factor structure. Hierarchical multiple regression examined incremental validity. Correlational analyses examined convergent validity. Cronbach's coefficient alphas and McDonald's omegas examined internal consistency. Pearson's r, t-tests, and analysis of variance tests examined relationships between demographic variables and PASS-20 scores. Confirmatory factor analyses supported the hierarchical factor structure (root mean square error of approximation = .061, standardized root mean residual = .038, comparative fit index = .940). Total and subscale PASS-20 scores had acceptable convergent validity and internal consistency (range = .75-.93). Hierarchical multiple regression found that total and subscale PASS-20 scores have adequate incremental validity, considering that they contributed uniquely to the prediction of generalized anxiety scores above and beyond other pain-related scores. Demographic variables were significantly related to total and subscale PASS-20 scores. Evidence supports the use of Spanish total and subscale PASS-20 scores in SSMACP. Exploratory evidence also informed on the possible consequences and predictors of their pain-related anxiety. The results also encourage pain research in specific populations from Latin America (eg, Mexican Americans). PERSPECTIVE: The Spanish PASS-20 has adequate psychometric properties in SSMACP. This instrument can help catalyze pain research in SSMACP by informing on their pain-related anxiety and by helping evaluate other pain-related instruments. Evidence also informed on pain-related anxiety in SSMACP.

Project description:BackgroundIn individuals with chronic obstructive pulmonary disease (COPD), anxiety and depression contribute to increased mortality and exacerbations, decreased physical functioning, and deteriorated health-related quality of life. The Hospital Anxiety and Depression Scale (HADS) is a patient-reported tool developed to measure symptoms of anxiety and depression in clinical settings. The HADS has been frequently used with individuals with COPD; however, its measurement properties lack critical appraisal in this population.ObjectiveThis review aims to summarize and critically appraise the validity, reliability, and responsiveness of the HADS in individuals with COPD.MethodsFive electronic databases (MEDLINE, Embase, Scopus, PsychINFO, and Web of Science) will be systematically searched. Articles will be included if they assessed the measurement properties of the HADS in COPD; were published in a peer-reviewed journal; and were written in English. The COSMIN (Consensus-based Standards for the Selection of Health Measurement Instruments) guidelines will be used to assess the methodological quality and level of evidence in the selected studies.ResultsTo date, 12 articles met the inclusion criteria and will be included in the systematic review. The results of the psychometric properties of HADS will be qualitatively summarized and compared against the criteria for good measurement properties. The overall quality of evidence will be graded using the modified Grading of Recommendations, Assessment, Development and Evaluation approach. We expect to complete the systematic review by December 2022.ConclusionsThis systematic review will be the first to evaluate the psychometric properties of the HADS in individuals with COPD. Given the negative impact of anxiety and depression on physical functioning and health-related quality of life, this systematic review provides an opportunity to use the HADS as a validated measurement tool for the assessment and treatment of anxiety and depression in individuals with COPD.Trial registrationPROSPERO CRD42022302064; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=302064.International registered report identifier (irrid)PRR1-10.2196/37854.

Project description:BackgroundStigma is common among patients with chronic illnesses. It affects the delivery of healthcare for not addressing the psychological components and may interfere with the patient's attendance to necessary health care services. Therefore, a valid and reliable instrument to measure anticipated stigma related to chronic illness is vital to inform possible interventions. This study aimed to translate the Chronic Illness Anticipated Stigma Scale (CIASS) into the Amharic language and evaluate its psychometric properties in Ethiopia.MethodsThe CIASS was translated into Amharic language using standard procedures. The Amharic version was completed by 173 patients (response rate 96%) with chronic illness from three referral hospitals in the Amhara region. Internal consistency was examined through Cronbach's alpha. Construct validity was evaluated by confirmatory factor analysis and convergent validity by using a Pearson correlation of P-value less than or equal to 0.05.ResultsThe internal consistency was estimated at Cronbach alpha of 0.92. By using a structural equation model, and modification indices a model fitness testing was run and shows a root mean squared error of approximation 0.049 (90% CI, 0.012-0.075). The structural validity results in 78.8% of confirmatory factor analysis showed from the extraction of the three-dimension (components). Validity tests for convergent by using Pearson correlation positively correlated with common mental distress and negatively correlated with quality of life-BREF, and the construct validity shows a good valid tool to CIASS.ConclusionThe Amharic language version of the chronic illness anticipated stigma scale shows a satisfactory level of reliability and validity on different psychometric measures of assessment. The tool may be useful for future researchers and patients with chronic illness in the Amharic-speaking population. Moreover, it will be used to see the psychological burden related to chronic illness and for comparison among international population groups.
