3 The Beery- Buktenica Developmental Test of Visual-Motor Integration Present by Asst. Prof. Dr. Nuntanee Satiansukpong

4 Objectives Upon completion of the study, students should be able to 1. Describe the VMI and the supplemental tests and their purposes 2. Describe the psychometric properties of the tests 3. Describe how to administer the test 4. Describe how to score and interpret the test results

5 Contents 1. The Overview of the VMI test and its supplemental tests 2. The psychometric properties of the VMI test and its supplemental tests 3. Administration, Scoring, and Interpretation

6 Overview of the VMI test and its supplemental tests Overview of the VMI test and its supplemental tests The VMI Test and The VMI Test and its two supplemental standardized tests: its two supplemental standardized tests: Visual Perception and Motor Coordination. Motor Coordination.

9 The Overview of the VMI test and its supplemental tests The purpose of the VMI and its supplemental tests are to 1. Identify significant difficulties in visual-motor integration, 2. Obtain needed services 3. Assess the effectiveness of educational and other intervention programs 4. Serve as a research tool.

10 The Overview of the VMI test and its supplemental tests Cautions: 1. If a child’s behavior during testing causes an examiner to suspect visual acuity or other special problem, he should be referred to a school nurse, an opthalmologist or other specialists. 2. No single test or score is sufficient for making a diagnosis or creating a treatment plan. Team evaluation and planning is always best whenever possible.

11 The Overview of the VMI test and its supplemental tests If a child performs poorly on the VMI, 1. It could be because he or she has adequate visual perceptual and/or motor coordination abilities, but has not yet learned to integrate, or coordinate, these two domains. 2. Alternatively, it is possible that the child’s visual and/ or motor abilities are deficient.

12 The Overview of the VMI test and its supplemental tests If a child performs poorly on the VMI, examiners frequently follow up a VMI with an assessment of visual perceptual and motor abilities.

13 The Overview of the VMI test and its supplemental tests The follow up can be done either with 1. Informal clinical evaluation (follow an outline on Manual, page 29-30) 2. Formal evaluation (use the supplemental tests). Note: If all three standardized tests are administered, they must be administered in the same order in which they were normed in order to yield valid results. The valid order is VMI, Visual Perception, Motor Coordination.

14 The Overview of the VMI test and its supplemental tests The standardized Visual Perception Test The child’s task is to identify the exact match for as many of the 27 stimuli as possible in a three-minute period.

15 The Overview of the VMI test and its supplemental tests The standardized Motor Coordination Test The child’s task is to simply trace the stimulus forms with a pencil without going outside double-lined paths. The child’s task is to simply trace the stimulus forms with a pencil without going outside double-lined paths. The test takes about 5 minutes to administer. The test takes about 5 minutes to administer.

16 The psychometric properties of the VMI test and its supplemental tests Item and format selection: Extensive review of literature and clinical experience Extensive review of literature and clinical experience 72 geometric forms were initially selected for the study 72 geometric forms were initially selected for the study 600 children between the ages of 2 and 15 years copied the 72 forms 600 children between the ages of 2 and 15 years copied the 72 forms Item analyses were made of the results, new forms were constructed, old forms were modified, and a developmental sequence of 30 forms was created. Item analyses were made of the results, new forms were constructed, old forms were modified, and a developmental sequence of 30 forms was created. Set criteria for selection (page 99) Set criteria for selection (page 99) 30 forms were administered to another 600 children 30 forms were administered to another 600 children Following an item analysis of results, 24 forms were selected Following an item analysis of results, 24 forms were selected

17 The psychometric properties of the VMI test and its supplemental tests Sample selection and Demographics The VMI was originally normed in 1964 on 1,030 Illinois children The VMI was originally normed in 1964 on 1,030 Illinois children It was cross-validated in 1981 with 2,060 Californian children and again in 1989 with a national sample of 2,734 children. It was cross-validated in 1981 with 2,060 Californian children and again in 1989 with a national sample of 2,734 children. It also has been normed in other countries It also has been normed in other countries The VMI and its supplemental Visual and Motor tests were normed in 1996 on 2,614 children, 3 to 18 years of age, living in the United States. The VMI and its supplemental Visual and Motor tests were normed in 1996 on 2,614 children, 3 to 18 years of age, living in the United States.

19 The psychometric properties of the VMI test and its supplemental tests Validity: 1. Content Validity: Item selection, item analysis 2. Concurrent Validity: - Drawing subtest of Wide Range Assessment of Visual Motor Abilities (WRAVMA).52 - Developmental Test of Visual Perception (DTVP-2) copying.75 - Comprehensive Test of Basic Skill (CTBS).63
