title: Reliability and validity of the Turkish version of the Nottingham Extended Activities of Daily Living Scale.
abstract: OBJECTIVE
  The aim of this study was to develop a Turkish version of the Nottingham Extended Activities of Daily Living Scale (NEADLS) and to assess its reliability and validity.
  
  
  METHODS
  Sixty healthy volunteers over 67 years old were included in the study. After translation, the Turkish version of the scale was filled in by each participant over a period of 2 weeks. Reliability was assessed by internal consistency, test-retest intraclass correlation coefficient (ICC) and Spearman's correlation. Converging validity was determined correlating the scale with the Modified Barthel Index (MBI).
  
  
  RESULTS
  The mean age of participants was 77+/-5.67 years. In the reliability studies, internal consistency within the subsections and items of the NEADLS was good and very good, with Cronbach's alpha values ranging between 0.84-0.93 and 0.74-0.97 respectively. The Cronbach's alpha for the total NEADLS score was also determined as 0.97. Test-retest intraclass correlation coefficients, determined as 0.97 in total score, ranged from 0.84-0.97 between items. The converging validity study for the NEADLS total score was correlated with the MBI and the r value was found statistically significant (r=0.84, p<0.0001).
  
  
  CONCLUSIONS
  The Turkish version of the NEADLS is a reliable and valid scale and can be used in activities of daily living assessment of Turkish elderly persons.
