title: Psychological predictors of participation in screening for cognitive impairment among community-dwelling older adults.
abstract: OBJECTIVE
  Detecting cognitive impairment in the earlier stages is important for preventing or delaying dementia. To develop intervention strategies that promote screening for cognitive impairment, it is essential to identify the modifiable predictors for participation in screening. The present study examined whether participation in screening for cognitive impairment was predicted by the constructs of the health belief model, dementia worry and behavioral intentions to undergo screening among older adults.
  
  
  METHODS
  The study used a prospective design. After a baseline questionnaire survey, participation in screening for cognitive impairment was followed for 6 months (n = 10 023). Participation in the screening, constructs of the health belief model (perceived susceptibility to dementia, perceived severity of dementia, perceived benefits of screening, perceived barriers to screening), dementia worry, behavioral intentions and demographic factors were measured.
  
  
  RESULTS
  A path analysis showed that the behavioral intention to undergo screening (path coefficient = 0.29) directly predicted participation in screening for cognitive impairment, whereas other psychological and demographic factors did not directly predict participation. The behavioral intention was explained by the perceived benefits of screening (path coefficient = 0.51), perceived barriers to screening (path coefficient = -0.19) and perceived susceptibility to dementia (path coefficient = 0.16).
  
  
  CONCLUSIONS
  Participation in screening for cognitive impairment was positively predicted by higher behavioral intention to undergo screening. In turn, this behavioral intention was mainly predicted by the perceived benefits of screening among older adults. These findings suggest that emphasizing the perceived benefits and encouraging behavioral intentions might promote participation in screening for cognitive impairment.
