The Occupational Abilities and Performance Scale (OAPS) demonstrates strong reliability and validity for assessing schizophrenic patients in vocational rehabilitation settings.

Area of Science:

  • Psychiatry
  • Psychometric Evaluation
  • Rehabilitation Science

Background:

  • The Occupational Abilities and Performance Scale (OAPS) was developed for individuals diagnosed with schizophrenia.
  • Previous evaluations of the OAPS's psychometric properties were necessary.

Purpose of the Study:

  • To evaluate the reliability and validity of the Occupational Abilities and Performance Scale (OAPS).
  • To assess the OAPS's suitability for schizophrenic patients undergoing vocational rehabilitation.

Main Methods:

  • 174 schizophrenic patients from a vocational rehabilitation unit were assessed using the OAPS at baseline and after 18 months.
  • Reliability was assessed through internal consistency, split-half, test-retest, and inter-rater agreement.
  • Validity was examined using predictive, concurrent, and construct validity (factor analysis).

Main Results:

  • The OAPS exhibited excellent internal consistency, split-half reliability, test-retest reliability, and inter-rater agreement.
  • The scale demonstrated good predictive and concurrent validity.
  • Factor analysis confirmed the construct validity, identifying five distinct components.

Conclusions:

  • The Occupational Abilities and Performance Scale (OAPS) is a reliable and valid instrument for assessing occupational abilities in schizophrenic patients.
  • The five-component structure identified through factor analysis provides further support for the OAPS's construct validity.
