[Sentence repetition test for measurement of grammatical develoopment in Farsi speaking children]

Valid identification, prevention, and treatment of language disorders are a high priority for the speech and language professionals. One method for studying language development is sentence repetition that is faster to implement and analysis than other procedures. The aim of this project was constructing sentence repetition test as a quick measure of grammatical potency in 2.5 to 4 year old children. Sentences appropriate for 2.5 to 4 year old children were selected during several stages by speech and language pathologist and linguists. The validity of sentences was assessed by professional masters in this theme. Subsequently, 41 sentences including those with 80% high validity were administered to 72 children in 3 groups [2.5-3, 3-3.5, and 3.5-4 year olds, gender matched]. The reliability was administered with a test-retest design across a 2 weeks interval. Content validity Index for this test was 80%. "Test-retest reliability" was used for reliability of this test. The Interclass correlation coefficient for this test was 0.95 and standard error measurement was 7.45. The average of scores for sentence repetition, between groups was significant [p<0.001, p<0.001, p=0.014]. This sentence repetition test has the appropriate validity and reliability as well as the capability of proper and quick assessment [screening] of grammatical development in 2.5 to 4 year old Persian speaking children

[ comparative study on motor skills in 5-year-old children with phonological and phonetic disorders]

Speech as a motor phenomenon requires repetitive and rapid function of articulatory organs performing extremely fine movements. Practice on motor skills results in facilitation in treatment progress of children with phonological disorders. The purpose of this study was to compare motor skills in 5-year-old children with phonological and phonetic disorders. Thirty-two children age 5 years, 16 with phonemical speech sound disorders and 16 with difficulty at a phonetic level participated in this study. TOLD Test was performed for linguistic skills investigation among children. Phonetic test, Wepman test, diadochokinesis and oral assessment was used for diagnosis between phonological and phonetic disorders. The children were also evaluated with Oseretsky motor developmental scale. In comparison, mean scores of movement skills between both groups showed significant difference [p=0.006] and children with phonetic disorder got significantly higher scores on all part of this test. The findings of this study support the idea that speech sound disorders are frequently associated with motor problems, and that type of articulation disorder affects the motor performance in a different way. Phonological disorders seem to have more impact on motor performance than phonetic disorders. The results authenticate the need to pay more attention to the motor skills of children with articulation disorders
