Introduction

Visual perceptual deficit commonly occurs in people with schizophrenia. The Test of Visual Perceptual Skills-4th Edition (TVPS-4) is a motor-free visual perceptual measure, which includes seven subtests: visual discrimination, visual memory, spatial relationships, form constancy, sequential memory, visual figure-ground, and visual closure. However, convergent validity and ecological validity of the TVPS-4 is largely unknown, which limits its use in clinical and research settings.

Objectives

The purpose of this study was to examine convergent validity and ecological validity in people with schizophrenia.

Methods

Ninety-nine people with schizophrenia were assessed the TVPS-4, the Mini Mental State Examination (MMSE), the Behavioral Assessment of the Dysexecutive Syndrome (BADS), and the Activities of Daily Living Rating Scale III (ADLRS-III). To evaluate convergent validity, Pearson’s r were calculated among the TVPS-4 and two cognitive measures (the MMSE and the BADS). To evaluate ecological validity, we computed correlation (r) between the TVPS-4 and the ADLRS-III.

Results

The TVPS-4 total score showed moderate correlations with two cognitive measures (r=0.65-0.70). The seven TVSP-4 domains revealed moderate correlations with two cognitive measures (r=0.42-0.69). Moderate correlation (r=0.56) was found between the TVPS-4 total score and the ADLRS-III. Moderate to high correlations (r=0.33-0.61) were noticed among the seven TVPS-4 domains and the ADLRS-III.

Conclusions

The TVPS-4 has good convergent validity and ecological validity in people with schizophrenia. The multiple domains of the TVPS-4 are useful to comprehensively identify visual perception deficits in people with schizophrenia. The TVPS-4 can adequately exhibit the degree of living independently in people with schizophrenia.
