Abstract:
Objective To develop a Quick Cognitive Screening Scale for Elder(QCSS-E) and examine its reliability and validity.Methods In the light of rating model of MMSE and MoCA,a screening scale was developed to assess cognitive function,which contained 47 items across twelve domains.Five hundred community subjects were interviewed with the QCSS-E,then 150 subjects were retested after two weeks,and 75 subjects were assessed with MMSE and CCAS.The test-retest reliability,internal consistency reliability,empirical validity and constmct validity of QCSS-E were calculated.Results The test-retest reliability and Cronbach's α coefficient were 0.972 and 0.814 for QCSS-E total score,0.656-0.911 and 0.679-0.746 for domain scores.There were low to moderate correlation of 0.133-0.612 among domain scores,correlation domain scores with total score ranged from 0.303-0.664.QCSS-E scores decreased with increasing agc,increased with the level of education increasing,and decreased with the aggravation of brain damage.The QCSS-E was significantly correlated with MMSE(r=0.886) and CCAS (r=0.899).Factor analysis got two factors accounting for 49.4％ of variance,which were named vulnerability factor and resistance to damage factor.Conclusion The stability,internal consistency,and validity of the QCSS-E are good and meet with psychometric standard.
