Effect of Educational Program Based on Health Literacy Index on SelfCare Ability Among Older Adults: A Randomized Clinical Trial

Health literacy index (HLI) was developed to provide a proper framework for educational material in all levels. So, the aim of this study was to determine the effect of education based on (HLI) on the self-care ability among older adults.

This randomized clinical trial was conducted with 68 older adults during the period of May–August 2019. The research setting was health centers in the south of Tehran, Iran. Samples were selected with considering the inclusion criteria. Then Block randomization was used to assign the participants into two groups. The intervention group for 4 weeks in groups of 8–10 in the intervention group. Self-care ability was measured using a self-care questionnaire in two stages, before and two months after the implementation of intervention. The control group received no education and only used the routine community house services. Statistical analyses were performed using the SPSS software (version 16.0). Data were analyzed using the Chi-square, Fisher’s exact test and independent t-test. P < 0.05 was considered statistically significant.

The mean total self-care ability scores in the intervention group were 165.38 ± 10.69 and 184.28 ± 10.07 before and after intervention, respectively. These scores in the control group were 163.65 ± 13.27 and 167.52 ± 13.58, respectively (P < 0.001). The results showed significant differences between the two groups regarding self-care ability after the intervention (P < 0.001).

The implementation of education based on HLI significantly improve the self-care behaviors in older adults. It is suggested that this approach should be established to fit of educational content appropriate to the age of the elderly in order to health promotion. Trial Registration: The trial was registered in the Iranian Registry of Clinical Trials on May 23, 2018, identifier: IRCT20170912036150N1.
