Validity and reliability evidence of Smart Start-2 in preschool-aged children with/without a developmental delay and/or a disability

<p> The purpose of this study was to investigate validity and reliability evidence of Smart Start-Second Edition (Zittel, Kim, &amp; Wessel, 2014) (Smart Start-2) in preschoolers with and without a disability. Thirty-two preschoolers with a disability and 28 preschoolers without a disability participated in the study. The mean age of all participants, preschoolers with a disability, and preschoolers without a disability were 50.98 months (<i>SD</i> = 7.86, range 37 &ndash; 64), 53.28 months (<i>SD</i> = 7.28), and 48.35 months (<i>SD</i> = 7.78), respectively. Each participant was asked to perform 12 fundamental movement skills. The participants&rsquo; fundamental movement skills performances were filmed and examined with Smart Start-2 and Test of Gross Motor Development-Second Edition (Ulrich, 2000) (TGMD-2) by three trained raters. For validity evidence of Smart Start-2, correlations between data of Smart Start-2 and TGMD-2 were examined with Pearson product-moment correlation coefficients. Intra-rater reliability and inter-rater reliability were also examined using a proportion of agreement, modified kappa coefficient, and intraclass correlation coefficient. Large correlations between data of Smart Start-2 and TGMD-2 were found for total score (<i>r</i> = .89, <i>p</i> &lt; .01), for sum of scores on locomotor skills (<i>r</i> = .92, <i>p</i> &lt; .01), and sum of scores on object control skills (<i>r</i> = .92, <i>p</i> &lt; .01). Across three raters, the average proportions of agreements for intra-rater using Smart Start-2 on all participants, preschoolers with a disability, and preschoolers without a disability were .92, .91, and .91, respectively. Across three raters, the mean of modified kappa coefficients for intra-rater reliability using Smart Start-2 on all participants, preschoolers with a disability, and preschoolers without a disability were .83 (<i>SD</i> = .09, range .52 &ndash; 1.00), .83 (<i>SD</i> = .09, range .60 - .96), and .83 (<i>SD</i> = .10, range .52 &ndash; 1.00), respectively. The mean of intraclass correlation coefficients for intra-rater reliability using Smart Start-2 on all participants, preschoolers with a disability, and preschoolers without a disability were .96 (95% confidence interval: .94 - .97), .96 (95% confidence interval: .90 - .97), and .96 (95% confidence interval: .93 - .98), respectively. </p><p> The average proportion of agreements for inter-rater using Smart Smart-2 on all participants, preschoolers with a disability, and preschoolers without a disability were .86, .87, and .86, respectively. The mean of modified kappa coefficients, across three raters, for inter-rater on all participants, preschoolers without a disability, and preschoolers without a disability were .71 (<i> SD</i> = .11, range .42 - .89), .72 (<i>SD</i> = .10, range .42- .87), and .69 (<i>SD</i> = .10, range .45 - .89), respectively. The mean of Intraclass correlation coefficients for intra-rater reliability using Smart Start-2 on all participants, preschoolers with a disability, and preschoolers without a disability were .93 (95% confidence interval: .89 - .96), .95 (95% confidence interval: .89 -.97), and .89 (95% confidence interval: .72 - .95), respectively. However, a one-way repeated measures ANOVA showed significant differences of the total scores of Smart Start-2 between raters. <b></b>The major findings of this study support evidence of concurrent validity and intra-rater reliability and inter-rater reliability of the Smart Start-2 for assessing FMS for preschoolers with/without a disability using 3 trained raters.</p>
