The aim of this study was to establish the construct validity of the
ocus on the F utcomes of O ommunication C nder U ix ( S 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‐IIdomains for: (i) pre‐intervention scores in communication ( r= 0.53, P< 0.001; 95% CI0.30–0.70) and socialization ( r= 0.67, P< 0.001; 95% CI0.48–0.80); (ii) change scores over‐time in communication ( r= 0.45, P< 0.001; 95% CI0.201–0.65) and socialization ( r= 0.39, P= 0.002; 95% CI0.13–0.60); and (iii) scores at post‐intervention for communication ( r= 0.53, P< 0.001; 95% CI0.30–0.70) and for socialization ( r= 0.37, P= 0.003; 95% CI0.11–0.50). 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.
