Introduction. Diagnosis of auditory processing disorders is difficult due to the lack of standardized tests and clinical procedures. Currently in Poland it is carried out in an increasing number of clinical centers by means of self-developed clinical tools or
commercially available tests for the English-speaking population.
Aim. The aim of the research was to verify the reference values of auditory processing tests, such as Masking Level Difference,
Dichotic Digit Test, Pitch Pattern Sequence and Duration Pattern Sequence, used as diagnostic tests of auditory processing in the population of Polish-speaking children, but developed for the English-speaking children population.
Material and methods. The study involved 45 children with normal intellectual development, aged 7 and 9 years. The presence of otolaryngological and neurological diseases was excluded. Auditory processing was assessed using MLD, DDT, PPS and DPS tests.
Results. In the younger group the DDT for the right ear and the PPS test results fall into the reference hinges for English-speaking population. MLD, DDT for the left ear and DPS tests results were lower than the reference values for the English-speaking population. In the older group, DDT results for the right ear and DPS were the same or higher than normative values. In three cases – MLD, DDT for the Left Ear and PPS results obtained are definitely lower than norms obtained for children from the
English-speaking population.
Conclusions. Some of the test results obtained by Polish-speaking children do not fall within the range of reference values, so there is a need to develop separate DDT, DPS and PPS test norms for Polish-speaking children.
