The Multnomah Community Ability Scale effectively measures functioning in chronically mentally ill individuals. This validated tool aids case managers in assessing disability severity and guiding patient care.

Area of Science:

  • Psychiatry
  • Psychology
  • Health Services Research

Background:

  • Chronic mental illness presents significant challenges for community-based care.
  • Accurate assessment of functioning is crucial for effective treatment and resource allocation.
  • Existing instruments may not adequately capture the nuances of disability in this population.

Purpose of the Study:

  • To develop and validate the Multnomah Community Ability Scale (MCAS).
  • To create a reliable and efficient instrument for assessing functioning in chronically mentally ill individuals.
  • To provide a tool for case managers to quantify client disability and inform service delivery.

Main Methods:

  • Development of a 17-item scale by case managers.
  • Rigorous reliability testing, including inter-rater and test-retest assessments.

  • Validation through correlation with criterion variables like hospitalization length and clinician ratings.
  • Main Results:

    • The Multnomah Community Ability Scale demonstrated good inter-rater and test-retest reliability.
    • Scale scores showed high correlations with established measures of clinical severity and outcomes.
    • The MCAS effectively predicted future hospital admissions.

    Conclusions:

    • The Multnomah Community Ability Scale is a reliable and valid instrument for assessing functioning in chronically mentally ill persons.
    • The MCAS can be utilized for case mix description, progress monitoring, service assignment, and reimbursement.
    • This scale offers a practical tool for improving care management in community mental health settings.
