Abstract
Background: To investigate HL (health literacy) and eHealth literacy (eHL) among two groups of asthma outpatients, those with prior asthma education and those without. In addition, we aimed to compare two shortened versions of a HL measure instrument.
Methods: A cross-sectional survey was conducted with a sample of adult asthma patients (n = 129). Half of them had received asthma patient education prior to the study (n = 64). The study collected demographic data, questions on HL (HLS-EU-Q16) and eHL (eHEALS).
Results: In the main analysis respondents’ mean HL values were almost identical in both groups, 11.9 (SD = 3.1) among trained and 11.8 (SD = 3.5) among untrained patients, demonstrating a problematic level of HL, according to the instrument. In the subdivision of sum scores, the HL level of trained patients was categorized more often as problematic (43%) than among untrained patients (20%). Bland-Altman plots of the 6-item and 16-item versions of the HLS-EU suggest only limited agreement between the versions. In terms of eHL, trained patients showed a mean of 3.0 (SD = 1.1) and untrained patients a mean of 3.2 (SD = 1.0). Analysis of HL and eHL showed no difference between groups.
Conclusions: No consistent differences between groups were found, suggesting that trained patients did not benefit from asthma education regarding HL and eHL. The 6-item and 16-item versions of the HLS-EU were not easily interchangeable, limiting its use in a busy outpatient practice.
