COOP Functional Health Assessment kaarten, gereviseerd door WONCA

Abstract

The COOP / WONCA Charts constitute a concise psychological scale designed to measure various dimensions of an individual’s health status and functional capacity. This instrument is an adaptation and revision of the original nine-item Dartmouth COOP Functional Health Assessment Charts, which were evaluated and refined by the WONCA (World Organization of Family Doctors).

The revised instrument consists of six core cards, each addressing a distinct dimension using a single question with five illustrated response options. The dimensions assessed include Physical Fitness, Mood State, Daily Activities, Social Activities, Health Changes, and General Health. Patients are asked to report their condition over the preceding two weeks. An optional seventh card is available to specifically quantify the level of pain experienced.

Purpose

The primary purpose of the COOP / WONCA Charts is to provide a quick, reliable snapshot of a patient’s self-reported functional health across several key domains. Developed primarily for use in primary care settings, the instrument facilitates rapid screening and monitoring of changes in health status over time, enabling healthcare providers to identify areas requiring intervention.

This assessment tool is particularly valuable due to its brevity and reliance on clear pictorial representations (pictograms), making it accessible to a wide range of patient populations, including those with lower literacy levels. It serves as a practical measure for evaluating the outcomes of care and assessing the overall impact of illnesses or interventions on daily life and general participation.

Construct

The core psychological construct measured by the COOP / WONCA Charts is Functional Health Status. This multidimensional construct encompasses how well an individual is able to perform their usual social roles and physical tasks, integrating both physical and mental well-being into a cohesive measure of capacity.

The six dimensions captured by the charts are designed to cover the core components of functioning recognized in modern health assessment frameworks, specifically focusing on Activities, Mental Functions, and General Participation. The assessment moves beyond simple disease diagnosis to evaluate the patient’s lived experience of health.

• Physical Fitness: Measures perceived physical capability and energy levels.
• Mood State: Assesses emotional well-being and psychological distress.
• Daily Activities: Focuses on ability to perform routine tasks (e.g., work, household duties).
• Social Activities: Measures engagement and participation in social life.
• Health Change: Gauges the patient’s perception of recent changes in their overall health.
• General Health: Provides a subjective global rating of health status.

Validity

The original Dartmouth COOP Functional Health Assessment Charts demonstrated robust face and content validity, as they were developed through extensive collaboration with healthcare practitioners and patients to ensure relevance to primary care. Subsequent revisions by WONCA aimed to enhance cross-cultural applicability and streamline the dimensions, further solidifying content validity.

Studies evaluating the revised COOP / WONCA charts have generally supported their concurrent and construct validity, showing significant correlations with longer, established measures of health-related quality of life, such as the SF-36, particularly in the domains of physical and mental functioning. The pictorial nature of the responses contributes positively to the instrument’s ecological validity in diverse clinical settings, especially for rapid Functional Health Assessment.

Reliability

The reliability of the COOP / WONCA Charts has been consistently demonstrated across various international studies, reflecting strong internal consistency and test-retest reliability, especially for the core functional dimensions. The brevity of the instrument generally minimizes respondent fatigue, which can be a confounding factor in longer self-report scales, thereby bolstering the stability of responses.

Specific reliability coefficients (e.g., Cronbach’s Alpha) for the individual items typically fall within acceptable ranges for screening instruments, affirming that the charts provide stable and consistent measures of the patient’s self-reported functional capacity over short periods.

Factor Analysis

Factor analytical studies performed on the original Dartmouth COOP Charts typically supported a multi-dimensional structure, reflecting the distinct nature of the constructs being measured (e.g., physical vs. mental dimensions). The transition from nine to six core cards in the WONCA revision was guided by factor analysis and evaluation criteria, aiming to reduce redundancy while maximizing the breadth of functional coverage.

The current six-card structure is generally interpreted as representing six distinct, yet interrelated, factors of health status. While a single global factor of general health exists, the utility of this psychological scale lies in its ability to differentiate specific functional deficits, supporting the maintenance of the individual items rather than relying solely on a composite score.

Instrument

Test Type: Questionnaire (Self-Report Scale)

Format: Six core cards (plus one optional card for pain), each featuring a single question and five pictorial response options. The assessment period covers the past two weeks.

Language Available: Dutch (Nederlandse versie: Scholten JHG, van Weel C), English (Original Dartmouth version), and numerous other international translations due to WONCA dissemination.

Population Group: General Population, Clinical Patients

Age Group: Adults and Seniors

Population Details: Suitable for primary care patients seeking a quick assessment of functional capacity and general well-being, covering functions such as activities, mental functions, and general participation.

Test Methodology: Brief, visual self-administered or interview-assisted assessment. Scores are typically summed or analyzed dimensionally, with higher scores indicating poorer functioning.

Permissions & Fee and Test Year

The original Dartmouth COOP Charts were developed starting in 1983 (Nelson E, et al.) and revised in 1987. The specific Dutch version was published in 1992 (Scholten JHG, van Weel C). The scale is widely used globally, often available for clinical and non-commercial research use.
