SWITCH- Swedish Intelligibility test for children, is a test thatmeasures intelligibility of children's speech through repetition of singlewords. The test is computer generated and consists of 1000 word listsrandomly selected for each assessment. The purpose of this study was toexamine the equivalence, reliability and validity in the word lists. Word listswere tested on ten children with typical language development (N group)and ten children with speech deviation (T group). The children were audiorecorded when they repeated two lists. Twenty speech therapy studentsassessed the intelligibility. Percentage of consonants correct (PCC) werecalculated. The results of each child´s two word lists were compared tocalculate the equivalence. Inter- and intraraterreliability were examined.Validity was examined by examining correlations between PCC andintelligibility, and by comparing the intelligibility of the N-group and Tgroup.The results showed that the word lists in SWITCH were equivalentand that the method was reliable and valid.
