“…Both indices have been widely used in analyses of language samples to measure morphological and syntactic complexity in TD and clinical populations (Brown, 1973;Hewitt, Hammer, Yont, & Tomblin, 2005;Price et al, 2008;Rescorla & Turner, 2015;Rice et al, 2010;Roberts et al, 2007;Sudhalter et al, 1991).…”

“…The index was originally developed for children between the ages of 24 and 48 months, although it has been used beyond that age range (Hewitt et al, 2005;Oetting et al, 2010;Rescorla & Turner, 2015). The usefulness of the IPSyn as a measure of expressive syntactic abilities in TD children and various clinical populations has been shown in several studies (Price et al, 2008;Rescorla et al, 2000;Rescorla & Turner, 2015;Roberts et al, 2007;Scarborough et al, 1991).…”

Purpose: This research explored syntactic growth in children with fragile X syndrome (FXS) over a 5-year period, and variability in growth in relation to autism symptoms, nonverbal cognition, maternal responsivity, and gender. Method: Language samples at 4 time points from 39 children with FXS, 31 boys and 8 girls, were analyzed using the Index of Productive Syntax (Scarborough, 1990) and mean length of utterance (Brown, 1973). The degree of autism symptoms was evaluated using the Childhood Autism Rating Scale (Schopler, Reichler, & Renner, 1988) at the first time point. Maternal responsivity estimates were averaged across time points. Results: Children with FXS showed significant syntactic growth over time and a significant plateau (quadratic trend) in the later observations. Children who exhibited more autism symptoms at Time 1 had significantly lower syntactic abilities over time than children who exhibited fewer autism symptoms. Nonverbal cognition significantly predicted mean length of utterance scores but not Index of Productive Syntax scores. Maternal responsivity was not a significant predictor of syntactic outcomes. Girls with FXS generally demonstrated better expressive syntax than boys with FXS with notable individual differences. Conclusion: Despite significant growth over time, expressive syntax is a vulnerable domain for children with FXS, especially for those with severe autism symptoms. Clinical implications arising from the current findings are discussed.

“…Rezultati našeg istraživanja pokazuju da niži skor leksič-ke raznovrsnosti predstavlja značajnu kliničku karakteristiku SJP, što potvrđuje rezultate studije Hjuita i saradnika (Hewitt et al, 2005). Hjuit i saradnici proučavali su leksičke i sintaksičke sposobnosti dece sa SJP kod ispitanika koji su bili ujednačeni prema uzrastu i obrazovnom nivou majke, kao što je slučaj i sa ispitanicima obuhvaćenim našim istraživanjem.…”

“…The present study examined the extent to which sample length affected the reliability of a University at Buffalo, NY two global lexical measures (i.e., total number of words and number of different words) and mean length of utterances in morphemes (MLUm) in parent-elicited conversational samples for 3-year-olds. These measures were chosen because they have been previously shown to reflect developmental changes in children (Brown, 1973;Miller, 1981;Templin, 1957) and to differentiate children with and without language impairment (Bedore & Leonard, 1998;Hewitt, Hammer, Yont, & Tomblin, 2005;Rice et al, 2010;Watkins et al, 1995).…”

Purpose: The goal of this study was to investigate the extent to which sample length affected the reliability of total number of words (TNW), number of different words (NDW), and mean length of C-units in morphemes (MLCUm) in parent-elicited conversational samples for 3-year-olds. Method: Participants were sixty 3-year-olds. A 22-min language sample was collected from each child during free play with the parent in the laboratory. Samples of 1, 3, 7, and 10 min were extracted from the 22-min samples. TNW, NDW, and MLCUm were computed from each shorter sample and the 22-min sample. TNW and NDW were adjusted by number of minutes for comparisons. The differences and correlations between each shorter sample cut and the 22-min sample on MLCUm and adjusted TNW and NDW were computed. Results: The shorter samples and the 22-min samples significantly differed in adjusted TNW and NDW, but not in MLCUm. TNW reached an acceptable reliability level (i.e., r = .90) in 7-min samples. NDW and MLCUm approached the acceptable reliability level (rs = .88) in 7-min samples and reached it in 10-min samples. Conclusion: For conversational language samples with similar collection procedures, samples of 7 to 10 min are desirable for calculating TNW, NDW, and MLCUm in 3-year-olds.
