title: Validity and Reliability of Thai Version of the Foot and Ankle Ability Measure (FAAM) Subjective Form.
abstract: BACKGROUND
  Self-administered questionnaires have become an important aspect for clinical outcome assessment of foot and ankle-related problems. The Foot and Ankle Ability Measure (FAAM) subjective form is a region-specific questionnaire that is widely used and has sufficient validity and reliability from previous studies.
  
  
  OBJECTIVE
  Translate the original English version of FAAM into a Thai version and evaluate the validity and reliability of Thai FAAM in patients with foot and ankle-related problems.
  
  
  METHODS
  The FAAM subjective form was translated into Thai using forward-backward translation protocol. Afterward, reliability and validity were tested. Following responses from 60 consecutive patients on two questionnaires, the Thai FAAM subjective form and the short form (SF)-36, were used. The validity was tested by correlating the scores from both questionnaires. The reliability was adopted by measuring the test-retest reliability and internal consistency.
  
  
  RESULTS
  Thai FAAM score including activity of daily life (ADL) and Sport subscale demonstrated the sufficient correlations with physical functioning (PF) and physical composite score (PCS) domains of the SF-36 (statistically significant with p < 0.001 level and ≥ 0.5 values). The result of reliability revealed highly intra-class correlation coefficient as 0.8 and 0.77, respectively from test-retest study. The internal consistency was strong (Cronbach alpha = 0.94 and 0.88, respectively).
  
  
  CONCLUSIONS
  The Thai version of FAAM subjective form retained the characteristics of the original version and has proved a reliable evaluation instrument for patients with foot and ankle-related problems.
