Abstract: (1492 Views)
Background and Objectives: This study determines the validity and reliability of the Persian version of the adaptive behavior assessment system (ABAS) scale in children aged 1 to 42 months in Tehran City, Iran.
Methods: The translation and adaptation were carried out based on the international quality of life instrument project protocol. After a pilot study, 253 parents of 1-42 month-aged children in Tehran City, Iran, completed the Persian version of the ABAS scale to check the construct validity by exploratory factor analysis and internal consistency. To determine reliability, 12 parents completed this scale after 2 weeks again.
Results: The translation desirability was obtained by suggestions of the expert group and cognitive interviews by mothers; subsequently, face validity was obtained. The content validity ratio was calculated at 0.59 according to the participation of 11 experts. The content validity ratio for item 25 (communication), items 18, 20, and 22 (community use), items 11, 14, 15, 17, 18, and 21 (functional pre-academic), and item 18 (leisure) was below the acceptable value (0.59); however, the remaining substances demonstrated an acceptable content validity ratio, leading to no items being removed.
The content validity index regarding the relevance for item 25 (communication), items 18 and 22 (community use), items 11, 18, 23, and 22 (functional pre-academic), and the clarity for item 9 (functional pre-academic) scored between 0.7 and 0.79, indicating required revision. The other items achieved an acceptable content validity index value.
The Cronbach α coefficient tested the reliability and internal consistency. This coefficient was 0.957 in communication, 0.957 in community use, 0.943 in the functional pre-academic, 0.961 in home life, 0.960 in health and safety, 0.952 in leisure, 0.948 in self-care, 0.947 in self-direction, 0.954 in social, and 0.962 in motor subscales, and 0.991 in total scale.
To determine the structural validity, according to the eigenvalue and the percentage explained by the first factor in each subscale, it was determined that a single-factor model is the most favorable condition for implementing factor analysis in the items of each subscale. In addition, according to the scree plot, the contribution of the first factor in each subscale in explaining the variance of the total items is significant and different from the contribution of the other factors. By calculating the intraclass correlation coefficient, a good correlation was obtained in nine subscales, and a moderate correlation was obtained in one subscale.
Conclusion: The adaptation validity and reliability of the ABAS scale have a desirable and acceptable quality. Also, the Persian version of this scale has content and construct validity, reliability in test-retest, and internal consistency. Therefore, the Persian version of the ABAS scale can be used in research as a tool to evaluate the adaptive behavior of 1 to 42-month Persian language children.
