Introduction to the OT-APST

The OT-APST is a standardised tool that enables occupational therapists to screen for visual perception across each of the major constructs of visual perception and praxis, including the problems most frequently occurring after stroke. It was developed by Deirdre Cooke, Occupational Therapist in Brisbane, Australia.

OT-APST Subscales

OT-APST Subscales include:
Agnosia
Visuospatial Relations
--- Body Scheme
--- Unilateral Neglect
Constructional Skills
Apraxia
Acalculia, and
Functional Skills

The functional skills subscale includes direct observation of several skills commonly impacted by visual perceptual impairment such as reading, writing, arithmetic, the ability to tell the time and to hold and manipulate a common object.

The OT-APST also examines insight, incorporates behavioural observations related to visual perceptual impairment and speed of information processing time.

The OT-APST is designed to require only simple verbal or motor responses for completion, and the use of just one hand for the mainipulative items.

Alternate methods of test administration are included for clients with expressive language problems. It is not suitable for people with receptive language problems or significant hearing impairment.

Clinically useful screening tool for visual perceptual impairment that is to be used in conjunction with functional task observation assessments.

Time to Administer.

The OT-APST takes 20 to 25 minutes to administer after a stroke

Test Reliability includes:

• Inter-rater reliability
• Intra-rater reliability
• Test-retest reliability

Test Validity includes:

• Face validity
• Content validity
• Construct validity
• Criterion validity
• Ecological validity

Australian Normative Data

Age-stratified normative data for 356 adults aged 16 – 97 years.
