Argues that none of the conventional methods for assessing attachment meet all criteria. Describes development of a 100-item sort for assessing secure attachment in toddlers, closely tied to Bowlby's control systems model of attachment. Evaluates the Q-sort in terms of criteria for valid thoery-based assessments that have applicability beyond this…

The paper reports data from four studies using the Language Development Survey (LDS), a screening tool for the identification of language delay in two-year-old children. The LDS was found to have excellent sensitivity and specificity. Prevalence data using the LDS are reported, comparing three different severity cutoffs. (Author/DB)

A newly revised parent questionnaire for the assessment of vocabulary and syntactic development, the MacArthur Communicative Development Inventory-Toddlers, was evaluated. Concurrent validity correlations demonstrated high validity for parent report in both domains and some ability to differentially assess the two. (Author/DB)

The internal reliability and concurrent validity of the Play Assessment Questionnaire (PAQ) was compared to that of the Minnesota Child Development Inventory with 170 deaf or hard of hearing infants and toddlers. The PAQ was found to be a useful nonverbal tool that assesses symbolic play behaviors and demonstrates a parallel development with…

Three studies with approximately 600 children were conducted to evaluate the validity and reliability of the three measures of the Communication and Symbolic Behavior Scales Developmental Profile. Findings support the use of the profile as a screening and evaluation tool for identifying children with developmental delays at 12 to 24 months of age.…

The concurrent validity of the Battelle Developmental Inventory was explored by correlating Battelle results with scores from the Bayley Scales in 30 infants with known or suspected disabilities. Both the pattern and strength of the obtained correlations support use of the Battelle to measure development in infants with handicaps. (Author/JDD)

This study, involving 67 children (ages 2 to 60 months) with motor delays, found that the Battelle Developmental Inventory (BDI) possessed moderate to high levels of concurrent validity with appropriate subtests from the Vineland Adaptive Behavior Scales and the Bayley Scales of Infant Development. (Author/JDD)

Tests the validity and reliability of a scale (Mental Development Scales: Birth to Three Years) designed to assess developmental levels of children from birth to three years. (HOD)

This study established content validity and reliability for the Infant Behavioral Summarized Evaluation, a rating scale for young children with autism. Analysis of videotapes for 89 children (ages 6-48 months) revealed a significant group of 19 items, including characteristic early autistic behaviors and some less commonly described (such as…

This study examined test characteristics of the Pediatric Language Acquisition Screening Tool for Early Referral-Revised (PLASTER-R), a set of developmental questionnaires for children 3 to 60 months of age. The PLASTER-R was moderately to highly successful in identifying children within normal limits for language development. Test-retest…

Rasch calibration procedures were applied to item-response data for the 1,262 infants and toddlers comprising the standardization sample for the Mental Scale of the Bayley Scales of Infant Development. Analyses tend to confirm the psychometric integrity of the instrument. (Author)

The Infant Parent Social Interaction Code was developed to measure infant-parent interaction utilizing four parent variables, four infant variables, and one dyadic variable for which operational definitions were developed. Preliminary and validation studies with a total of 232 infants and toddlers suggest the measure reveals important interactive…

Thirty children (under 24 months of age) referred to an early intervention program were administered 3 developmental assessments. Although the Griffiths' Mental Development Scales correlated well with the Bayley Scales of Infant Development and the Battelle Developmental Inventory, the Griffiths' age equivalents were considerably higher than the…

Two parent report inventories geared at assessing language skills in toddlers are examined, in terms of reliability, validity, and application. The MacArthur Communicative Development Inventory: Toddlers and the Language Development Survey are compared and their combined use in handicap identification is discussed. (PB)
