Construct validity of the FOCUS© (Focus on the Outcomes of Communication Under Six): a communicative participation outcome measure for preschool children.

OBJECTIVE: The aim of this study was to establish the construct validity of the Focus on the Outcomes of Communication Under Six (FOCUS©). This measure is reflective of concepts in the International Classification of Functioning Disability and Health--Children and Youth framework. It was developed to capture 'real-world' changes (e.g. communicative participation) in preschoolers' communication following speech-language intervention. METHOD: A pre-post design was used. Fifty-two parents of 3- to 6-year-old preschoolers attending speech-language therapy were included as participants. Speech-language therapists provided individual and/or group intervention to preschoolers. Intervention targeted: articulation/phonology, voice/resonance, expressive/receptive language, play, and use of augmentative devices. Construct validity for communicative participation was assessed using pre-intervention and post-intervention parent interviews using the FOCUS© and the communication and socialization domains of the Vineland Adaptive Behavior Scales-II (VABS-II). RESULTS: Significant associations were found between the FOCUS©, measuring communicative participation, and the VABS-II domains for: (i) pre-intervention scores in communication (r = 0.53, P < 0.001; 95% CI 0.30-0.70) and socialization (r = 0.67, P < 0.001; 95% CI 0.48-0.80); (ii) change scores over-time in communication (r = 0.45, P < 0.001; 95% CI 0.201-0.65) and socialization (r = 0.39, P = 0.002; 95% CI 0.13-0.60); and (iii) scores at post-intervention for communication (r = 0.53, P < 0.001; 95% CI 0.30-0.70) and for socialization (r = 0.37, P = 0.003; 95% CI 0.11-0.50). CONCLUSIONS: The study provided evidence on construct validity of the FOCUS© for evaluating real-world changes in communication. We believe that the FOCUS© is a useful measure of communicative participation.

Fetal alcohol syndrome: a description of oral motor, articulatory, short-term memory, grammatical, and semantic abilities.

Formal communication skills assessments were completed on eight children with diagnosed forms of fetal alcohol syndrome (FAS) ages four and one-half to nine and one-half years. Non-FAS children ages three and one-half to six and one-half years matched for ethnic background, living situation, and nonverbal cognitive ability served as controls. All but one of the FAS subjects demonstrated abnormalities of the speech mechanism within at least one major valve along the vocal tract. Mental age inconsistent articulation abilities were found in three FAS subjects when matched for nonverbal cognitive ability. The FAS children exhibited mental age inconsistent abilities in the comprehension and use of grammatical markers both in repetition and in spontaneous language tasks. Further, the FAS subjects also demonstrated reduced capacity to process and store critical elements when compared with non-FAS children. Clinical implications for the assessment of children with FAS are outlined.
