Abstract :Purpose: The aim of this study was to assess the reliability and validity of the ACTIVLIM questionnaire for Turkish-speaking neuromuscular disease (NMD) patients with the Rasch analysis. Methods: 169 NMD patients were included to the study. The independence level regarding activities of daily living was assessed using the Functional Independence Measurement (FIM) scale while activity limitation was evaluated with the Activlim questionnaire. All assessments were performed twice, at the beginning of the study and 15 days later. Statistically analysis were done by using Rasch method. Results:   95 children with a median age of 10 and 74 adults with a median age of 34.5 years were included to the study. Seventy patients (41.7%) were assessed a second time. Starting with 22 items, one item (ACTIVLIM 5- Sitting on the toilet) displayed disordered thresholds, necessitating collapsing of categories. According to test/retest reliability, none of the items showed differential item functioning.  Internal consistency of the scale is sufficent (Cronbach’s alpha  0.94). The scale showed expected correlation with FIM scores ( Pearson 0.95) which  revealed external construct validityof the scale. Conclusion: ACTIVLIM is found as a reliable and valid questionnaire that can be used in the Turkish NMD population to assess activity limitation.
