Ideally, speech pathologists should try to collect 50 to 200 complete and understandable expressions (Rice et al. The research assistants who collected, transcribed, and coded the samples were unaware of the children's language status. For conversational language samples with similar collection procedures, it is recommended to take samples for 7 to 10 minutes to calculate TNW, NDW, and MLCum in 3-year-old children. The mLUM values were calculated for the first 10 and 20 statements, the 10 and 20 in the middle, the last 10 and 20 statements, every second statement (50 quasirandom statements), every fifth statement (20 quasirandom statements), every 10th statement (10 quasirandom statements) and the total sample.
However, even with 50 to 100 expressions, LSA can still place significant pressure on speech-language pathologists (SLP) who work with children with language problems, given that the median number of SLP cases in a full-time school is 47 children per week, with a range of up to 240 children (American Speech, Language, and Hearing Association, 201). The 22-minute sample) was carried out for each dependent variable, a Bonferroni correction was adopted for control for type I error (Field, 200), which yielded a minimum level of significance of. The children were divided into smaller (between 2 years, 8, and 5 years) and older (between 6, 0, and 13 years) groups because Heilmann and his colleagues speculated that younger children would be more variable in their production and, therefore, might need longer samples to obtain reliable language sample measures. Darley and Moll (1960) examined how sample length affected the reliability of the internal consistency of mean response length (MLR, a measure similar to the average length of expressions in words) in 150 typical 5-year-old children who used different pronunciation cuts in the same language samples.
A 30-minute sample of conversational language was collected from each child while playing freely with their parents in a child-friendly testing room located in the laboratory. A conversational sample of 50 sentences was obtained from each child through a description task with images carried out by the examiner in the child's home. So that the current findings can be generalized to 3-year-old children in clinical practice, doctors may want to collect a slightly longer sample (e.g., the study used a pre-recorded sample) and recommend that you let Google do its work and then review the sample once more to make sure that you agree with Google. Previous studies have tended to focus on the reliability of language sample measures because, in psychometry, reliability reflects how consistent or repeatable a measure is (Bruton, Conway, & Holgate, 2000).
