Determinants of Dementia-Preventive Behaviors: A Scoping Review Based on the PRECEDE Model

Abstract

As dementia is becoming a great challenge worldwide, modifying its risk factors is a primary preventive approach. However, there is a scarcity of integrated efforts to determine dementia-specific factors that influence preventive behaviors, particularly when considering a theoretical framework. Therefore, this scoping review aimed to map the evidence on factors affecting dementia-preventive behaviors based on the PRECEDE framework. Five electronic databases—PubMed, PsycINFO, CINAHL, EMBASE, and Cochrane CENTRAL—were searched for articles published until May 2022, and only peer-reviewed studies were included to gather robust evidence. During the initial search, 37,331 articles were retrieved. Of these, 22 articles met the inclusion criteria and were included in the evidence synthesis. The scoping review identified 28 specific determinants within the six conceptual categories of the PRECEDE framework, thereby highlighting the multi-dimensional nature of factors influencing dementia-preventive behaviors. Future studies should consider multilevel and multi-dimensional personalized strategies to promote dementia-preventive behavior.
