Objective: The recent Belgian adaptation for singers of the Voice Handicap Index (VHI) was translated and readapted in Swedish. This study’s aim was to evaluate the validity and reliability of this Swedish version. Method: In a parallel group design, 96 healthy singers and 30 singer-patients with various diagnoses completed a Swedish version of the singer adapted VHI. An evaluation of the Swedish voice health status instrument was carried out. In average, delays between test-retest ranged from 14 to 16 days. Validity and reliability as well as the internal coherence and group differences were assessed. Results: The singer-patient group scored significantly higher than the control group. Reliability was confirmed by high Cronbach’s alpha (>.78) for test-retest scores as well as each subscales. In particular, test-retest stability in both groups was confirmed by high values for Cronbach’s alpha (>.8). For both the control and patient groups, test and retest scores compared closely to previous reports with respect to overall scores. Retest results were slightly lower than initial test scores. Conclusions: The Swedish translation of the adapted VHI for singers (RHI-s) is valid and reliable and shows sensitivity to the singer's concerns. It can be considered a useful tool in the clinical assessment of Swedish healthy or pathological singers.
