AUDITORY/VISUAL PERCEPTION AND MOTOR
• The Motor Activities Program was revised to be more user friendly. The MAP is the instruction/treatment program for the PDMS-3. It contains units organized develop- mentally by skill area. After a child’s motor skills have been assessed and the exam- iner has completed all sections of the Profile/ Summary Form, the examiner selects units from the MAP to use to facilitate the child’s development in specific skill areas. • The manipulative kit has been expanded to include most of the manipulatives needed for testing to better ensure the standardized administration of items. • The Peabody Motor Development Chart has been updated. It provides the examiner with a convenient reference for the motor skills measured by the PDMS-3 and the ages at which 75% of the normative sample performed the skill. Each of the subtests is represented along with numerous illustrations of children demonstrating the behav- iors described in the text. ( Note: B&W chart is included in the PDMS-3 Complete Kit; a full-color version [product #15078] is available separately.) • The PDMS-3 norms are based on an all-new sample of 1,452 children who were tested from Spring of 2016 through Spring of 2021. • The demographic characteristics of the sample were stratified by age to conform to those of the projected U.S. under 5 years of age population for the year 2021 as reported in the ProQuest Statistical Abstract of the United States 2021 (ProQuest, 2021) and are thereby representative of the U.S. population. The demographic characteristics of the sample were also stratified by age for geographic region, race, ethnicity, gender, parent education, and household income. • New and extensive studies of test bias (both differential item functioning and sub- group comparison studies) were conducted, indicating the PDMS-3 possesses little or no bias regarding gender, race, or ethnicity. • New and extensive criterion-prediction validity studies were conducted to demon- strate the validity of the PDMS-3’s subtests and composites, including diagnostic accuracy and receiver operating characteristic/area under the curve (ROC/AUC) analyses. Diagnostic accuracy analyses are particularly rigorous techniques for establishing validity involving the computation of a test’s sensitivity index, specificity index, and ROC/AUC. These studies indicate that the PDMS-3 is a highly valid mea- sure of motor skills. • New studies of construct-identification validity, including studies of age differences, subgroup performance, relationship to language, relationship to social-emotional development, and relationship to adaptive behavior were conducted. Factor analyses of the test’s structure by age were also performed. These studies indicated that the PDMS-3’s internal structure is sound, and its results are valid for a wide variety of subgroups, as well as for a general population. • Access to the new PDMS-3 Online Scoring and Report Syste m is now included and provides an efficient and easy way to obtain PDMS-3 scores and corresponding nar- rative.
PEABODY MOTOR DEVELOPMENT CHART Our ever-popular motor development milestones reference chart has been updated to provide a convenient reference for the motor skills measured by the PDMS-3. Skill acquisition was quantified using the age at which 90 percent of the PDMS-3 norma- tive sample was able to successfully complete the task. Each of the five motor devel- opment subtests is represented, along with numerous illustrations of the milestone skills. This 38" wide by 26" tall wall chart continues to serve as a quick and colorful guide for occupational therapists, physical therapists, diagnosticians, early intervention specialists, adaptive physical education teachers, psychologists, and others who are interested in examining the motor abilities of young children. The colorful wall chart is printed on heavy paper and is varnished for protection. Corner holes are pre-drilled for easy hanging, and the chart comes in a study card- board tube to prevent creases. The new third edition of the chart is also available as a pack of 25 black and white Parent Charts (8.5" x 11", folded 4-pages), perfect for sharing with parents, parapro- fessionals, and colleagues. All those concerned with child motor development will find themselves frequently referring to these charts and mini-posters for their own refer- ence, as a training tool, or as a starting point for discussion and collaboration.
