Title: | Development and initial validation of the Preschool Imitation and Praxis Scale (PIPS) | Authors: | VANVUCHELEN, Marleen Roeyers, Herbert De Weerdt, Willy |
Issue Date: | 2011 | Source: | Research in Autism Spectrum Disorders, 5 (1), p. 463-473 | Abstract: | The goal of this study was to develop and subsequently evaluate the internal construct and criterion-related validity of the Preschool Imitation and Praxis Scale (PIPS). Different task characteristics were selected considered to be important as unravelled in research in apraxic adults to tap a broad range of possible imitation mechanisms. Participants included 498 children without disabilities (1–4.9 years) and 47 children with autism spectrum disorders (ASD) (1.9–4.5 years). Exploratory factor analysis disclosed 4 dimensions in the scale, labelled: goal directed versus non-goal directed procedural imitation and single versus sequential bodily imitation. Internal consistency for the PIPS scale (alpha = .97) and subscales was high (alpha ranged from .79 to .96). In both samples, the PIPS scale score was strongly related to age (r = .78, respectively r = .56). Significant relationships between the PIPS score and mental, language, motor ages in the ASD sample supported criterion-related validity (r ranged from .59 to .74). The PIPS appears to have fundamentally sound psychometric characteristics, although more research is needed. | Keywords: | Child; Assessment; Bodily and procedural imitation; Preschool Imitation and Praxis Scale (PIPS); Validity; Autism spectrum disorders; Dual route theory of imitation | Document URI: | http://hdl.handle.net/1942/13246 | ISSN: | 1750-9467 | e-ISSN: | 1878-0237 | DOI: | 10.1016/j.rasd.2010.06.010 | Category: | A1 | Type: | Journal Contribution |
