چکیده
این پژوهش با هدف ساخت، رواسازی، اعتباریابی و هنجاریابی نرم‌افزار مقیاس بین‌المللی عملکردی لایتر انجام گرفت. روش پژوهش روان‌سنجی بود. به این منظور پس از ساخت نرم‌افزار برای اعتباریابی آزمون از بین کلیة کودکان 3 تا 6 سال شهر اصفهان 240 نفر به‌عنوان نمونه به روش نمونه‌گیری خوشه‌ای چندمرحله‌ای انتخاب و در پژوهش شرکت کردند. برای بررسی روایی سازه از مقیاس رشد اجتماعی واینلند (براهنی و اخوت،1352) و برای بررسی روایی همزمان، از آزمون هوشی استنفورد بینه (افروز و کامکاری،1389) استفاده شد. ضرایب پایائی بازآزمایی نرم‌افزار مقیاس بین‌المللی عملکردی لایتر برای سنین 2 سال و 1 ماه تا 4 سال و 5 ماه 71/0 (001/0 P≤) و برای سنین 4 سال و 6 ماه تا 6 سال و 9 ماه 82/0 (001/0 P≤) به دست آمد. همچنین آلفای کرون باخ برای سنین 2 سال و 1 ماه تا 4 سال و 5 ماه 75/0و برای سنین 4 سال و 6 ماه تا 6 سال و 9 ماه 83/0 به دست آمد. ضریب همبستگی نرم‌افزار مقیاس بین‌المللی عملکردی لایتر و مقیاس واینلند مثبت و معنی‌دار بود (61/0=r). ضرایب همبستگی بین هوش‌آزمای استنفورد- بینه و نرم‌افزار مقیاس بین‌المللی عملکردی لایتر در خرده مقیاس کلامی برابر با (34/0=r) و در خرده‌مقیاس غیرکلامی برابر با (75/0=r) بود. نتیجه این‌که نرم‌افزار مقیاس بین‌المللی عملکردی لایتر، ابزاری روا و پایا برای انجام ارزیابی هوشی کودکان است.

Abstract
The present study aimed at developing and validating the Leiter International Performance Scale Software. The research method was psychometrics. Therefore, after developing the software, to validate the test, from among all 3-6 year old children in the City of Isfahan 240 children were selected using the stratified random sampling and participated in the study. To investigate the construct validity of the scale, the Vineland Social Maturity Scale and to investigate the concurrent validity, the Stanford–Binet Intelligence Scale were used. The test-retest reliability coefficient of the total score of the Leiter International Performance Scale Software for 2 year and 1 month to 4 year and 5 month children was 0.71 (p≤0.001). In addition, the reliability coefficient of the total score of the Leiter International Performance Scale Software for 4 year and 6 month to 6 year and 9 month old children was 0.82 ((p≤0.001). The Chronbach’s alpha coefficient for 2 year and 1 month to 4 year and 5 month old children was 0.75 and for 4 year and 6 month to 6 year and 9 month old children, it was 0.83. The correlation coefficient of the Leiter International Performance Scale Software with the Vineland Social Maturity Scale was positive and significant (r = 0.61). The correlation coefficient between the Stanford-Binet Intelligence Scale and the Leiter International Performance Scale Software, as an evidence for the concurrent validity, was r = 0.34 in the verbal subscale and r = 0.75 in the non-verbal subscale. The results of the present study indicated that the Leiter International Performance Scale Software can be considered as a valid and reliable instrument for measuring children’s intelligence.
