Background: Detecting cognitive impairment in its earliest stages can prevent or delay the onset of dementia. Despite many policies that support cognitive screening, the screening rate is only 10.6% in China. Limited evidence is available on the cognitive screening intention of populations at high risk for dementia and the predictors of cognitive screening. This study aimed to assess the cognitive screening intention of people at high risk for dementia and to identify potential predictors of their cognitive screening intention. Methods: A cross-sectional survey involving 205 subjects at high risk for dementia was conducted between November 2021 and April 2022 in two large communities in Guangzhou, China. Data were collected using a self-designed questionnaire based on the planned behavior theory, including demographic characteristics and the theory of planned behavior (TPB) structures. Structural equation modeling (SEM) was used to identify predictors of cognitive screening intention. Results: The mean total score of cognitive screening intention was 8.54 ± 3.60, and 54% of the total number of subjects showed a intention to under cognitive screening. Religion, residence, family history of dementia, and health status were influencing factors of cognitive screening intention. Subject norms (r = 0.468, P < 0.01), perceived behavioral control (r = 0.695, P < 0.01), and attitude (r = 0.647, P < 0.01) were positively correlated with the intention. Fit indices indicated that the final structural model was well reflected, and that the research model was satisfactory. It was found that all hypotheses were supported. Based on the findings of the structural equation model, attitudes (path coefficient = 0.24, P < 0.01), subjective norms (path coefficient = 0.25, P < 0.01), and perceived behavioral control (path coefficient = 0.43, P < 0.01) had significantly positive effects on behavioral intentions.Conclusions: Half of the population at high-risk for dementia in the present study had the intention to undergo cognitive screening. The screening behavioral attitude, subjective norms, and perceived behavioral control have a direct positive effect on screening behavior intentions. The perception of behavioral control was the strongest predictor of intent to undergo cognitive screening. Further studies are needed to establish the interventions to facilitate cognitive screening intention, and their perceived behavioral control deserves more attention. |
