[Goal oriented measurement with the IRES questionnaire: a critical interim statement].

Area of Science:

• Rehabilitation research
• Outcome measurement
• Psychometrics

Background:

• Goal Oriented Measurement (ZOE) was proposed by Gerdes (1998) to individualize outcome measurement in rehabilitation.
• This method aims to tailor measurement to specific patient needs and rehabilitation goals.
• ZOE is differentiated from Goal Attainment Scaling and Patient Preferences in its approach.

Purpose of the Study:

• To critically evaluate the Goal Oriented Measurement (ZOE) method.
• To identify and discuss the limitations of ZOE as implemented with the IRES questionnaire.
• To assess the suitability of ZOE for individualizing outcome measurement in rehabilitation research.

Main Methods:

• Critical review of the Goal Oriented Measurement (ZOE) concept.
• Analysis of the IRES (Indicators of Rehabilitation Status) questionnaire in the context of ZOE.
• Comparison of ZOE with related measurement approaches like Goal Attainment Scaling.

Main Results:

• Identified insufficient validity in selecting clinically relevant problems.
• Highlighted potential issues such as regression artifacts and unsuitably aggregated scores.
• Noted concerns regarding reactivity, changes in individual problems, and potential deteriorations in unselected problems.

Conclusions:

• Goal Oriented Measurement (ZOE) exhibits substantial shortcomings that limit its utility.
• The method requires significant methodological improvements to enhance its validity and reliability.
• Further research is needed to refine ZOE or develop alternative approaches for individualized rehabilitation outcome measurement.
