Reliability and Validity of the Telephone-Based eHealth Literacy Scale Among Older Adults: Cross-Sectional Survey

Background: Only a handful of studies have examined reliability and validity evidence of scores produced by the 8-item eHealth literacy Scale (eHEALS) among older adults. Older adults are generally more comfortable responding to survey items when asked by a real person rather than by completing self-administered paper-and-pencil or online questionnaires. However, no studies have explored the psychometrics of this scale when administered to older adults over the telephone. Objective: The objective of our study was to examine the reliability and internal structure of eHEALS data collected from older adults aged 50 years or older responding to items over the telephone. Methods: Respondents (N=283) completed eHEALS as part of a cross-sectional landline telephone survey. Exploratory structural equation modeling (E-SEM) analyses examined model fit of eHEALS scores with 1-, 2-, and 3-factor structures. Subsequent analyses based on the partial credit model explored the internal structure of eHEALS data. Results: Compared with 1- and 2-factor models, the 3-factor eHEALS structure showed the best global E-SEM model fit indices (root mean square error of approximation=.07; comparative fit index=1.0; Tucker-Lewis index=1.0). Nonetheless, the 3 factors were highly correlated (r range .36 to .65). Item analyses revealed that eHEALS items 2 through 5 were overfit to a minor degree (mean square infit/outfit values <1.0; t statistics less than –2.0), but the internal structure of Likert scale response options functioned as expected. Overfitting eHEALS items (2-5) displayed a similar degree of information for respondents at similar points on the latent continuum. Test information curves suggested that eHEALS may capture more information about older adults at the higher end of the latent continuum (ie, those with high eHealth literacy) than at the lower end of the continuum (ie, those with low eHealth literacy). Item reliability (value=.92) and item separation (value=11.31) estimates indicated that eHEALS responses were reliable and stable. Conclusions: Results support administering eHEALS over the telephone when surveying older adults regarding their use of the Internet for health information. eHEALS scores best captured 3 factors (or subscales) to measure eHealth literacy in older adults; however, statistically significant correlations between these 3 factors suggest an overarching unidimensional structure with 3 underlying dimensions. As older adults continue to use the Internet more frequently to find and evaluate health information, it will be important to consider modifying the original eHEALS to adequately measure societal shifts in online health information seeking among aging populations.Open Access Fundin

Background Numerous studies have been conducted over the past 15 years to assess safety culture within healthcare facilities; in general, these studies have shown the pivotal role that managers play in its development. However, little is known about what healthcare managers actually do to support this development, and how caregivers and managers represent managers’role. Thus the objectives of this study were to explore: i) caregivers and managers’ perceptions and representations of safety, ii) the role of managers in the development of safety culture as perceived by themselves and by caregivers, iii) managers’ activities related to the development of safety culture. Methods An exploratory, multicentre, qualitative study was conducted from May 2014 to March 2015 in seven healthcare facilities in France. Semi-structured interviews were conducted with managers (frontline, middle and top level) and caregivers (doctors, nurses and nurse assistants) and on-site observations of two managers were carried out in all facilities. A thematic analysis of semi-structured interviews was performed. Observed activities were categorised using Luthans’ typology of managerial activities. Results Participants in semi-structured interviews (44 managers and 21 caregivers) expressed positive perceptions of the level of safety in their facility. Support from frontline management was particularly appreciated, while support from top managers was identified as an area for improvement. Six main categories of safety-related activities were both observed among managers and regularly expressed by participants. However, caregivers’ expectations of their managers and managerial perceptions of these expectations only partially overlapped. Conclusions The present study highlights current categories of managerial activities that foster safety culture, and points out an important gap between caregivers’ expectations of their managers, and managerial perceptions of these expectations. The findings underline the need to allow more time for managers and caregivers to talk about safety issues. The results could be used to develop training programs to help healthcare managers to understand their role in the development of safety culture
