Test-Retest Reliability and Minimal Detectable Change of the Test of Visual Perceptual Skills-Third Edition in Patients With Stroke
Nov 01, 2016 Test of Visual Perceptual Skills-Third Edition. The TVPS-3 measures visual perception using 7 subscales, each containing 2 practice items and 16 test items. All items are presented in a multiple choice format. Each item is scored as 0 (wrong answer) or 1 (right answer). The sum score of the test items in each subscale ranges from 0 to 16. abstractPurpose: The Test of Visual Perceptual Skills-Third Edition (TVPS-3) with seven subscales has been used to assess visual perception in patients with stroke. The purpose of this study was to investigate ecological validity, convergent validity, and discriminative validity of the TVPS-3 in patients with stroke.
abstractObjectives To examine the test-retest reliability, calculate minimal detectable change (MDC), and report internal consistency of the Test of Visual Perceptual Skills-Third Edition (TVPS-3) in patients with stroke. Design Repeated-measures design (at an interval of 2wk). Setting Medical center. Difference from TVPS-3: The TVPS-4 utilizes the 112 black and white designs from the TVPS-3, plus an additional 14 new images. The new images were added to expand the range of easier items and improve the discriminative ability of the test for younger or more impaired individuals. The Test Kit includes: Manual, Test Plates, and 25 Record Forms.
Abstract
The TVPS-3 is used by many professionals, including learning specialists, occupational therapists, optometrists, and rehabilitation specialists. The TVPS-3 remains an easy to use assessment to determine the visual perceptual strengths and weaknesses of students aged 4-0 through 18-11. Visual perception is an important ability that enables one to make sense out of what is seen (in contrast to visual acuity tests which determine just that something was seen by the individual).

The MDC values of the overall scale and the subscales were 18.1 and 5.4 to 7.1, respectively. The MDC% value of the overall scale was 16.2% (30%), indicating substantial random measurement errors. The Cronbach α of the 7 subscales were .71 to .89, indicating good internal consistency.ConclusionsOur results showed that the overall scale of the TVPS-3 had satisfactory test-retest reliability. However, the subscales demonstrated insufficient test-retest reliability. Therefore, the subscales should be used cautiously to explain the test results over repeated assessments in patients with stroke

Description
The TVPS-4 is an easy to use instrument that helps you determine a child’s visual perceptual
strengths and weaknesses. It was designed for use by occupational therapists, psychologists,
education diagnosticians, developmental optometrists, learning specialists, and other assessment
professionals.
How to Use the Assessment
The TVPS-4 uses black and white designs as stimuli for all of the perceptual tasks arranged in a
developmental progression. Responses are made vocally or by pointing, which is ideal for children
who may have motor, speech, hearing, neurological, or cognitive impairments. There are 16 plates for
each perceptual area; each is normed separately so that you can reliably differentiate the various
visual perceptual processes.
