Arabic heart failure self-care scale gains local validation in Saudi patients
An Arabic version of the European Heart Failure Self-care Behaviour Scale has now been tested in a Saudi cohort, filling a gap that has long complicated routine assessment of heart failure self-care across Arabic-speaking settings. For clinicians, the value is straightforward: a translated tool only matters if it measures the same behavior construct with enough precision to guide care, compare outcomes, and support research. This study tackled both the language barrier and the psychometric one.
The work centered on the EHFScBS-12 and EHFScBS-9, two widely used instruments designed to capture how well patients with heart failure follow daily self-care behaviors such as limiting fluids and salt, keeping appointments, taking medications, weighing themselves, and responding to symptoms. In a condition where decompensation can begin with small lapses in self-management, a valid questionnaire is not a cosmetic research tool. It is a clinical measurement instrument tied to whether teams can identify patients who are struggling before congestion, dyspnea, and readmission follow.
Cross-cultural adaptation preserved the core self-care construct
Investigators used forward-backward translation and cross-cultural adaptation procedures before testing measurement properties in 137 patients with HF recruited from a governmental hospital in Riyadh. The mean age was 59 years, and 61.3% were male. The cohort was evaluated using the translated EHFScBS versions alongside the Self-Care Heart Failure Index version 6.2 and the Perceived Stress Scale-10 to probe convergent and divergent validity.
The adaptation process matters because self-care is not merely a checklist of behaviors; it is shaped by language, family roles, symptom interpretation, and expectations around chronic illness. A phrase that works in one culture can lose meaning in another if it does not map onto the patient’s lived experience. The study’s design recognized that problem and treated translation as a measurement issue rather than a simple linguistic one.
The 9-item scale fit the data more cleanly than the 12-item version
The clearest finding emerged from confirmatory factor analysis. The 12-item scale produced fit indices that were not convincing on first pass: RMSEA was 0.084 with a 90% CI of 0.059 to 0.108, CFI was 0.824, and NFI was 0.706. Those values suggest the original structure did not align especially well with this Arabic-speaking sample, even after post-hoc modification.
A different picture appeared with the 9-item scale. Its CFA showed stronger fit, with RMSEA of 0.042 and CFI of 0.969. In practical terms, the shorter version tracked the observed data more closely and did so with less structural friction. For a bedside instrument, that is not a trivial detail. When a scale reflects the underlying behavior construct more cleanly, it becomes more trustworthy for both screening and research use.
Reliability stayed acceptable in both versions
Internal consistency was acceptable for both scales, at 0.75 for one version and 0.72 for the other. Those figures do not suggest perfect redundancy, and they do not need to. A self-care scale must be coherent without collapsing every item into the same question. The goal is to measure related behaviors that together reflect how patients manage a chronic disease with daily consequences.
Both versions also demonstrated convergent and discriminant validity. In plain clinical terms, the measure behaved as expected alongside related constructs and separated itself from unrelated ones well enough to support further use. The content validity figures were strong, with I-CVI values ranging from 0.85 to 1 and an S-CVI of 0.95, showing that the item set retained strong expert agreement after translation.
Why the shorter tool may be the better bedside option
Heart failure self-care is complicated by fatigue, symptom variability, polypharmacy, and the slow drift from compensated to decompensated status. In that setting, a shorter questionnaire can carry real operational advantages if it preserves measurement quality. Fewer items mean less respondent burden, less clinician time, and a higher chance the scale will be used consistently in outpatient and inpatient settings.
The 9-item instrument also appears more compatible with routine workflows in settings where time and staffing are limited. A measure that is too long often fails not because it is conceptually weak, but because busy clinics stop using it. By showing better model fit in this sample, the shorter Arabic version has a better chance of surviving contact with real practice.
The study still leaves localization unfinished
The investigators stop short of claiming universal Arabic applicability. Their own data support the need for independent cross-validation in separate samples from Saudi Arabia and other Arabic-speaking countries before the instrument can be treated as broadly generalizable. Cross-cultural validity remains an open question, especially across regions where educational background, dialect, health literacy, and disease education differ.
That caution is appropriate. A psychometric study can demonstrate that a tool works in one sample; it cannot prove that the same structure will hold everywhere Arabic is spoken. Different health systems also shape self-care behavior, from access to follow-up care to how patients are taught to monitor weight or adjust salt intake. Those differences can alter how respondents interpret items, even when the translation is fluent.
Still, the clinical implication is immediate and concrete. Arabic-speaking clinicians and researchers now have evidence that the EHFScBS-9 performs better than the 12-item version in this Saudi cohort, while both forms remain acceptable enough to support measurement of self-care behavior. For a population facing a substantial heart failure burden and repeated hospital use, the ability to quantify self-care in a culturally appropriate way is a necessary step toward better tailored education, surveillance, and intervention studies.
