title: First report on the reliability and validity of speech handicap index in native English-speaking patients with head and neck cancer.
abstract: BACKGROUND
  Posttreatment speech problems are seen in nearly half of patients with head and neck cancer. Although there are many voice-specific scales, surprisingly there is no speech-specific questionnaire for English-speaking patients with head and neck cancer. The aim of this study was to validate the Speech Handicap Index (SHI) as the first speech-specific questionnaire in the English language.
  
  
  METHODS
  In all, 55 consecutive patients in follow-up for oral and oropharyngeal cancer completed the SHI and University of Washington Quality of Life Questionnaire (UWQOL V.04). Thirty-two patients completed both questionnaires again 4 weeks later to address test-retest reliability.
  
  
  RESULTS
  Internal consistency, test-retest reliability, construct validity, and group validity of the SHI were found to be highly significant (p < .01) using Cronbach's alpha, Spearman's correlation coefficient (r), and Mann-Whitney U tests.
  
  
  CONCLUSIONS
  The SHI is a precise, highly reliable, and valid speech assessment tool for patients with head and neck cancer. Further dedicated studies using the SHI in patients with head and neck cancer would be useful.
