Abstract
Background
This study examined the impacts of an educational intervention based on the Progressively Lowered Stress Threshold (PLST) extended model on caregiving for people with dementia (PWD).
Method
This study was conducted in Isfahan, Iran, from May 2016 to June 2018, with 38 caregivers of PWD as participants assigned to an intervention group. Data were collected using a multi-sectional, researcher-developed questionnaire that recorded the demographic characteristics, and measured the dementia-related knowledge and caregiving practices of the participants. The questionnaire and an educational program were designed in three parts according to the educational needs of caregivers to enhance their practice, skills, and ability to handle challenging behaviours in PWD. The questionnaire’s face validity was confirmed by expert review, and its reliability was assessed with Cronbach’s alpha coefficient (knowledge section, 0.838; practice section, 0.802). The sampling method used was convenience sampling, and none of the caregivers refused to receive the educational content. Therefore, the evaluation of the program lacks a randomized controlled group. To tailor the intervention program to the participants’ needs, the educational content was based on the PLST extended model.
Results
The mean scores for knowledge and practice increased following the intervention (P < 0.05). An educational intervention, using the PLST extended care model, thus produced positive impacts in improving the knowledge and practice of caregivers of PWD.
Conclusion
Educating caregivers with the PLST extended model, with a specific focus on the cultural and religious backgrounds of societies, is recommended.
