title: The person-centred care of older people with cognitive impairment in acute care (POPAC) scale - psychometric evaluation.
abstract: OBJECTIVE
  To test the reliability and validity of the Person-centred care of Older People with cognitive impairment in Acute Care scale to determine nurses' perceptions of person-centred care.
  
  
  BACKGROUND
  One-third of older adults admitted to hospital are at risk of serious hospital-acquired complications such as falls, infections and pressure injuries because of cognitive impairment. These risks can be reduced through person-centred practices. The Person-centred care of Older People with cognitive impairment in Acute Care scale is a self-report staff instrument to explore the extent to which person-centred practices are undertaken; however psychometric testing is limited.
  
  
  METHODS
  A cross-sectional sample of acute care nurses (n = 240) in Queensland, Australia completing self-report questionnaires. Psychometric analyses of item performance, reliability and validity were conducted.
  
  
  RESULTS
  Item analysis revealed independent items. One item was removed due to negatively associating with the scale, improving total Cronbach's alpha from 0.76 to 0.84. The three original factors were maintained with regrouping of items. Confirmatory factor analysis confirmed the revised model.
  
  
  CONCLUSIONS
  The revised Person-centred care of Older People with cognitive impairment in Acute Care scale had satisfactory psychometric properties when used as a total scale.
  
  
  CONCLUSIONS
  Scale brevity and simplicity together with rigorous development and testing indicates that the revised Person-centred care of Older People with cognitive impairment in Acute Care may be useful for quality improvement programmes into the care of older people in hospitals.
