Tilpasning, Standardisering og Validering af den Danske Version af Test for Reception of Grammar-2 (TROG-2)

The following study presents results from the pilot as well as the final version of the Danish adaptation of Dorothy Bishop's Test for Reception of Grammar 2 (TROG-2). The original British test was modified according to Danish grammar. It was the piloted, re-modified and finally standardized and validated against different linguistic measures. The pilot study including 102 monolingual Danish children in the age range 8-13 years showed an increase in the mean number of correct blocks in TROG-2 with age indication an improved grammatical comprehension. In addition to TROG-2 the children in the pilot study were tested on the adapted Danish versionof the relative clause comprehension test developed bu Friedmann (1998). The results from the children's performance on the two receptive grammar tests correlated need for further modifications of the test in order to attain a valid Danish verion of TROG-2. The final Danis version of TROG-2 was standardized with 501 monolingual Danish children in the age range 4-15 years. The sample was balanced for gender and data was collected from all geographical areas of Denmark (Jutland, the Island of Bornholm, the Island of Fyn and Zealand). The final Danish version of TROG-2 was validated against a standardized Danish vocubulary comprihenseion test The Viborg Test (Pedersen & Skyrum Kjøge, 2005) and results show that the language measures correlate strongly (r=0,80, p=.001). As a whole we can conclude that the Danis version of TROG-2 seems a reliable and valid test of monolingual Danish-speaking children's development of receptive grammar.
