Populations

Key Descriptions

  • 36 items involving 2 dimensional configurations presented on separate cards (also called "plates").

    Each card has an example and a multiple choice response set of 4 alternatives (A,B,C,D) from which the participant chooses the item that matches the example. 

    Participants points to or says the letter that corresponds to the desired option.

    Guidelines have been developed for the administration and interpretation of the test for adult populations, however, the original test materials are required for administration (Bouska & Kwatny 1982).

    One point is given for each correct response. Scores range from 0 to 36. In addition to summary scores, the time to complete each item is noted and an average time per item calculated.

Normative Data

Normative data (U.S.) is available for adults aged 18 – 80 (Bouska & Kwatney 1982), normative for older adults (aged 50+) has been proposed.

 

Adult norms can be found in:

Bouska, M. and E. Kwatny (1982). "Manual for the application of the motor-free visual perception test to the adult population." Philadelphia, PA: Temple University Rehabilitation Research and Training Center.

Test/Retest Reliability

MVPT-R Children: (Colarusso & Hammill, 1972; reported in Brown et al, 2003; n = 167 children of various ages)

  • Excellent test-retest reliability, 20 days between assessments  (r = 0.77 to 0.83)

 

MVPT-3 Adults and Adolescence: (Colarusso & Hammill, 2003; n = 28 participants aged 11 to 84 years)

  • Excellent test-test reliability, 34 days between assessments (r = 0.92)

Internal Consistency

MVPT-R Children: (Colarusso & Hammill, 1996; sample = children of various ages)

  • Excellent internal consistency (r = 0.81 to r = 0.84)

Criterion Validity (Predictive/Concurrent)

Acute Stroke: (Cate & Richards, 2000; n = 30 CVA & 20 non-CVA participants; mean age = 58.7 (13.43) years; mean time since stroke onset = 4.25 (3.49) weeks)

  • Excellent concurrent validity: Visual screening scores (acuity, visual field deficits, oculomotor skills and visual attention/scanning) and MVPT scores (r = 0.75)

Construct Validity

No significant difference between patients with right hemisphere versus left hemisphere lesions. However, patients with right hemisphere lesions generally demonstrated poorer performance on the (original) MVPT (York & Cermak, 1995)

Content Validity

MVPT-R: (Brown et al, 2003; mixed sample)

Development based on five visual categories proposed by Chaifant & Scheffelin (1969) as well as an item analysis.
