A Model of Clinical Supervision for Preservice Professionals in Early Intervention and Early Childhood Special Education

The authors present a model of clinical supervision to guide preservice professionals embarking on a career in early intervention and early childhood special education. Established models of clinical supervision in the general education field are described, followed by a description of the clinical supervision model used by the University of Oregon Early Intervention Program. Priorities and methods for research are suggested.

Eligibility Determination Using a Curriculum-Based Assessment: A Further Examination

This study examined the accuracy of a curriculum-based assessment for use during the eligibility process for Individuals with Disabilities Education Improvement Act (IDEA) services. The study extended a previous investigation in which performance scores of children without disabilities on the Assessment, Evaluation, and Programming System (AEPS) were used to set cutoff scores at 6-month age intervals. These cutoff scores were then tested for service eligibility classification accuracy. The present study specifies and examines cutoff scores at more specific age intervals and performance domains. Present study findings largely replicated results of the original study. The AEPS cutoff scores were found to accurately classify most eligible children but did overidentify some ineligible children. The data from these two studies suggest that, to the extent allowed by state criteria, early intervention/early childhood special education personnel may be able to use the AEPS test as a valid assessment tool while qualifying children for IDEA services.

Developmental screening in a Canadian First Nation (Mohawk): psychometric properties and adaptations of ages & stages questionnaires (2nd edition)

BackgroundThe need for early intervention tools adapted to the First Nation culture is well documented. However, standards derived from First Nation communities are absent from the literature. This study examines the psychometric properties of an adaptation of a caregiver-completed screening tool, the Ages & Stages Questionnaires (ASQ), for the Mohawk population.MethodsParticipants who completed the questionnaires include 17 teachers, along with the parents of 282 children (130 girls and 152 boys) between the ages of 9 and 66 months who attend the Child and Family Center Mohawk Territory, Quebec.ResultsFor the internal consistency of the four questionnaires (36-, 42-, 48- and 54-month intervals), Cronbach’s alphas varied between .61 and .84. Five results were below 0.60: “gross motor” (Q36 and Q42), “problem solving” (Q36) and “personal-social” (Q36 and Q42). A comparison of the results shows that parents and teachers agreed in 85% of the cases concerning the referral of the child for further evaluation. Moreover, the group discussion with the parents revealed that the use of the questionnaire was appreciated and was deemed appropriate for use within the community.ConclusionThe results show that the ASQ is a screening test that may be appropriate for use with children from communities that are seemingly very different in terms of geographic, climatic and cultural backgrounds. This preliminary study with the Child and Family Center appears to support further study and the use of the ASQ with the Mohawk population.

A Psychometric Study of the Infant and Toddler Intervals of the Social Emotional Assessment Measure.

Psychometric and utility studies on Social Emotional Assessment Measure (SEAM), an innovative tool for assessing and monitoring social-emotional and behavioral development in infants and toddlers with disabilities, were conducted. The Infant and Toddler SEAM intervals were the study focus, using mixed methods, including item response theory modeling and classical test theory. Results using a Rasch one-parameter logistic model indicated model fit statistics were consistent for age and item difficulty as well as for ability and item characteristics. Classical test theory analyses generally confirmed the developmental structure; mean scores increased with age and were significantly correlated across 6-month increments. Reliability studies indicated strong internal consistency and moderate interrater agreement between teachers. Test–retest reliability results completed by parents online indicated significant agreement. Overall, 90% of parents reported the SEAM asked appropriate questions and took less than 10 min to complete.

Examining Internal Structures of a Developmental Measure Using Multidimensional Item Response Theory

Evidence supporting the internal structure of an assessment can provide support for its scoring mechanisms. A total of 1,691 young children in the United States were assessed by their parents using the 16-month questionnaire of the Ages and Stages Questionnaires, Third Edition (ASQ-3), and results were used to study the internal structure and dimensionality of the ASQ-3 using item response theory (IRT)/Rasch models. Data were analyzed using IRT including unidimensional and multidimensional Rasch Partial Credit Models to examine four theory-based internal structures. Results supported the hypothesis that the ASQ-3 measures a unidimensional construct—the overall development of children—while preference was given to a more precise multidimensional construct of five interrelated domains. However, concerns emerged regarding the extremely high correlations between items in the fine-motor and problem-solving domains. Findings provide implications for the test developers in terms of item refinement to improve measurement of underlying constructs.

Adapting and validating a developmental assessment for chinese infants and toddlers: The ages & stages questionnaires: Inventory

The Chinese government has announced the 2013 Guidelines for developing a national system for early detection of disability among children under 6 years of age. However, given limited resources, challenges exist with developmental measures required in the 2013 Guidelines. In order to meet the needs for a more accurate and cost-efficient measure for developmental assessment, the Ages & Stages Questionnaires: Inventory (ASQ:I) was translated into Simplified Chinese, and validated on a regional sample of 812 Chinese children ages from 1 to 25 months. Results indicated that the Chinese ASQ:I domain scores increased across childrens age. When dividing the sample into seven age intervals, Cronbachs alpha in each interval ranged from 0.59 to 0.96 across five domains. When using the whole sample for analyses, item expected a posteriori/plausible value (EAP/PV) reliability was above 0.99 in all domains, test-retest reliability using intra-class correlation analyses ranged from 0.95 to 0.99, and the agreement with the concurrent measure ranged from 0.29 to 0.89. Domain scores on the ASQ:I correctly predicted 92-99% of participating childrens disability status. Findings suggested that the Chinese ASQ:I has adequate psychometric properties and thus provides a promising alternative measure for screening and progress monitoring in young children in China. Implications for future research and implementation are discussed.
