The Mere-measurement Effect of Patient-reported Outcomes

The Communicative Participation Item Bank (CPIB) aims to assess communication participation in all kinds of communication disorders.

The Vocal Fatigue Handicap Questionnaire (VFHQ) and the Vocal Fatigue Index (VFI) aim at reflecting vocal fatigue. Both have been adapted to reflect purely positive wording.
