Anpassning av ett ordförrådstest : En reviderad svensk översättning av Peabody Picture Vocabulary Test - IV

Sammanfattning: Speech and language pathologists (SLP) use vocabulary tests as one of several means of investigating and evaluating suspected speech and language disorders. A test widely used when assessing receptive vocabulary is Peabody Picture Vocabulary Test (PPVT) IV. Several different Swedish translations of PPVT-IV exists today, most of which have not yet been studied. Since earlier studies have confirmed that Swedish translations of PPVT lack a steadily increasing level of difficulty, Swedish SLPs are uncertain as to how applicable the test is on a Swedish population. In this study, a Swedish translation of PPVT-IV was revised with the purpose of constructing a steadily increasing level of difficulty. The study comprised 172 monolingual children from grade 1, 3, 5, 7 and 9, tested by the authors of this thesis. The participants were recruited from ten schools in Uppsala. For 21 of the 228 PPVT-IV items, two different translations were tested to enable adjustment of the level of difficulty afterwards. Based on the results of the participants, a revised translation was developed with a more steadily increasing level of difficulty. Further adaptations are still needed before standardised norms can be developed for a Swedish population. The results for every grade displayed an average score above the American age standards. Participants from grade 1 performed one year above, participants from grade 3, 5 and 7 all performed two years above, and participants from grade 9 performed six to eight years above the American age standards for the corresponding age.
