It’s also very easy to administer, and the results are exceedingly reliable.

Additionally, all assessment factors are based on the age of the child, allowing for more accurate developmental assessments.

Do we find practice effects based on subtest order?
Statistically, we did not find practice effects based on subtest order for any subtests. The number of items that can be scored through observation of the child also minimizes the likelihood of practice effects with the Communication subtests. However, there are some reasons for recommending that Receptive Communication be administered prior to Expressive Communication. Some stimulus items are similar across content and repeated exposure to these pictures may make it easier for the child to recognize them in the Receptive Communication subtest. In addition, many young children must establish rapport with the examiner before expressing themselves vocally by naming objects or speaking to the examiner; the Receptive items can help familiarize the child with tasks and encourage vocalizations.
What is the Bayley scale?
The Bayley Scale of Infant and Toddler Development (Bayley-III) is designed to assess the developmental functioning of infants and young children 1-42 months of age .#N#Purpose#N#The Bayley Scale of Infant and Toddler Development (Bayley-III) is designed to assess the developmental functioning of infants and young children 1-42 months of age. The primary purpose of the Bayley-III is to identify suspected developmental delays in children through the use of norm-referenced scores and to provide information in order to plan appropriate interventions rooted in child development research. In addition, the Bayley-III can be used to monitor a child’s progress during intervention and helps to develop an understanding of a child’s strengths and weaknesses in relation to five developmental domains: cognitive, language, motor, social-emotional and adaptive behavior. The Bayley-III has a flexible administration format to accommodate variability in the child’s age and temperament. However, deviations for the standard procedures, such as phrasing or repeated presentation of a test item, invalidate the use of norms according to the test manual.
What is the Bayley III test?
The primary purpose of the Bayley-III is to identify suspected developmental delays in children through the use of norm-referenced scores and to provide information in order to plan appropriate interventions rooted in child development research.
How reliable is the adaptive behavior scale?
The Technical Manual presents inter-rater reliability for the Adaptive Behavior Scale, which is rated by the child’s parents or primary caregiver. The sample included 56 children aged 0 months – 5 years 10 months each rated by two parents. Reliability coefficients ranged between .59-.86. These are unacceptable according to the standards in the field and suggest a high degree of inconsistency between ratings (Salvia, Ysseldyke and Bolt, 2010). Another issue is that As well, this sample does not reflect the entire age range of the Bayley-III. Therefore inter-rater reliability for the Adaptive Behavior Scale is insufficient.
Why is Bayley III not valid?
However, results obtained from administration of the Bayley-III are not valid due to lack of an adequate reference standard and lack of sensitivity and specificity data. This seriously limits the test’s discriminant accuracy and ability to properly identify children with a developmental delay or disorder.
What is social emotional scale?
The Social-Emotional Scale is based on The Greenspan (Greenspan, 2004). In spring 2003 a sample of 456 children aged 15 days to 42 months who matched the U.S. 2000 census were administered The Greenspan to generate normative data for the Social-Emotional Scale. The sample was stratified according to parent education level, race/ethnicity and geographic region. The sample was divided into eight age groups each containing a minimum of 50 participants. No mention is made regarding how these children were selected or what percentage, if any of them had clinical diagnoses. These sample sizes are too small according to the standards in the field, which recommends sample sizes of 100 or more (APA, 1974). If a small sample is used then the norms are likely to be less stable and less representative (McCauley and Swisher, 1984).
Why is the reliability of the cognitive, motor and language scales considered insufficient?
Thus, the test-retest reliability for the Cognitive, Motor and Language Scales is considered insufficient due to a insufficient inclusion of all ages, small sample sizes and because almost all correlation coefficients were less than the accepted minimum standard.
Can Bayley III be used for diagnostics?
According to the test manual, the Bayley-III may only be administered by trained professionals who have experience in the administration and interpretation of comprehensive developmental assessments and should have completed some formal graduate or professional training in individual assessment. The Bayley-III should not be used to diagnose a specific disorder in any one area. Rather, poor performance in an area should be used to make recommendations for appropriate services.
How Do Examiners Use the Bayley Scales?
The examiner rates the child's performance on each task , and scores are totaled. Raw scores are compared to tables of scores for other children the child's age. This process yields a standard score that enables the examiner to estimate the child's development compared to other children his age. This allows the examiner to determine if the child has developmental delays, judge how significant they are, and develop an appropriate early intervention program for the child. This information can assist early service providers with diagnosing disabilities.
