The VHI was translated to Swedish and retranslated to English. The questionnaire was tried in two phases on a total of 23+144 patients and 12+58 voice healthy controls. The reliability was calculated with Cronbach's alpha, ICC and Pearson's correlation coefficient. The validity was estimated by independent T-test.The difference in VHI-T scores between the patients and the voice-healthy controls was significant (p = < 0,01) and there was a good correlation of the test- retest occasions. The reliability testing of the entire questionnaire showed an alpha value of r = 0,90 and that for the Throat subscale separately a value of r = 0,87 which shows a high degree of reliability.For the estimation of self-perceived throat and voice problems the scale on throat related problems together with the present Swedish translation of the Voice Handicap Index, (VHI) the VHI-Throat, proves to be a valid and reliable instrument. The throat subscale seems to help revealing a category of symptoms that are common in our patients. These are symptoms that have not earlier been possible to cover with the questionnaires designed for use in the voice clinic.Patient-reported symptoms together with laryngostroboscopy and perceptual analysis of the voice are essential for the evaluation of voice in logopedic and phoniatric practice [1,2]. A number of instruments for the self-rating of voice problems have been developed for use in the voice clinic. The Voice Handicap Index (VHI) [3] along with the shortened VHI: VHI-10 [4]; the Voice Activity and Participation Profile (VAPP)[5]; the Voice-Related Quality of Life (VrQoL)[6]; the Voice Outcome Survey (VOS) [7] and the Voice symptom scale (VoiSS) [8] are all designed for measuring perceived handicap and quality of life, and perceived limitations of participation and activity.Symptoms related to the throat, such as frequent throat clearing, irritated throat, sensation %U http://www.biomedcentral.com/1472-6815/10/5
