Adaptation of the Disaster Literacy Scale to Individuals Aged 60 Years and Older and Exploring its Psychometric...

This methodological study aimed to adapt the DLS, introduced for individuals aged 18-60 years, to those aged 60 years and older and to determine its psychometric properties.

We collected the data between December 15, 2021 and April 18, 2022. We carried out the study with a sample of 60 years and older living in the city center of Burdur, Turkey. The sample was selected using snowball sampling, a non-probability sampling technique. We collected the data using a questionnaire booklet covering an 11-item demographic information form and the DLS. We utilized reliability and validity analyses in the data analysis. The analyses were performed on SPSS 23.0, and a P value < 0.05 was considered statistically significant.

The mean age of the participants was found to be 68.29 (SD = 6.36). The 61-item measurement tool was reduced to 57 items by removing a total of 4 items from the scale. We also calculated Cronbach's α values to be 0.936 for the mitigation/prevention subscale, 0.935 for the preparedness subscale, 0.939 for the response subscale, and 0.945 for the recovery/rehabilitation subscale.

As adapted in this study, the DLS-S can be validly and reliably used for individuals aged 60 years and older.
