Health and Digital Health Literacy in Community-Dwelling Older Adults: Effects of a Health Promotion-Based Psychoeducational Intervention

The main aim of this study is to evaluate the effect of a health promotion-based psychoeducational intervention on Health Literacy (HL) and Digital Health Literacy (DHL) levels in older people. This one-group pre–post design study includes a sample of community-dwelling older people, at risk of social isolation, sedentary lifestyles, or physical deterioration. A multidimensional assessment protocol, with specific measures of HL and DHL, was applied before and after the intervention. The psychoeducational intervention includes 20 sessions, conducted by a multidisciplinary team and focused on four core areas (Health Promotion, Interpersonal Relationships and Citizens’ Rights, Health Literacy, and Digital Health Literacy). Non-parametric statistics tests (Wilcoxon signed-rank test) were used, since data did not follow a normal distribution. Seventy-nine older persons participated, with a mean age of 71.7 (SD = 4.6), mostly female (66%) and with basic education (91%). There was a statistically significant increase in the mean total HL score (Z = −3.132; p = 0.002; effect size r = 0.76) and DHL score (Z = −4.735; p < 0.001; effect size r = 0.61) after the intervention, reflecting an improvement in HL and DHL levels. This study showed that this intervention was effective in improving the HL and DHL levels of older adults. These results are particularly noteworthy, considering that HL and DHL are modifiable factors that influence self-management, as well as health outcomes in older adults.
