| Summary: | Background: Sustained visual attention is a prerequisite for learning and
memory. The early evaluation of attention in childhood is essential for their
school and career success in the future. The aim of this study was to design,
development and investigation of psychometric properties (content, face and
convergent validity and test-retest and internal consistency reliability) of the
computer - based sustained visual attention test (SuVAT) for healthy preschool
children aged 4-6 with their special needs.
Methods: This study was carried out in two stages: in the first stage computerbased
SuVAT in two versions original and parallel were developed. Then the
test-retest and internal consistency reliability using intra-class correlation and
Cronbach’s alpha coefficients respectively were examined; Face validity was
calculated through ideas gathering from 10 preschool children and content
validity evaluated using CVI and CVR method and convergent validity of
SuVAT with CPT was assessed using Pearson correlation.
Results: The developed test showed a good content and faces validity, and
also had excellent test-retest reliability. In addition, the assessment of internal
consistency indicated the high internal consistency of the test (Cronbach’s
alpha=0.869). SuVAT and CPT test demonstrated a positive correlation upon the
convergent validity testing.
Conclusion: SuVAT with good reliability and validity could be used as an
acceptable sustained attention assessment in preschool children. |
