This study offers practical item generation guidance for measure development, using a Table of Specifications (TOS) to create a patient-reported compassion measure. The TOS aided consensus on 109 initial items and response scales.
Area of Science:
- Nursing Research
- Psychometrics
- Patient-Reported Outcome Measures
Background:
- Existing measure development guidelines lack practical, systematic item generation strategies.
- Developing reliable and valid patient-reported measures requires robust item generation.
- The construct of compassion is central to nursing care.
Purpose of the Study:
- To provide practical guidance on systematic item generation in measure development.
- To demonstrate the utility of a Table of Specifications (TOS) in item generation.
- To develop a valid and reliable patient-reported measure of compassion.
Main Methods:
- Literature review on measure development and item generation.
- Application of a Table of Specifications (TOS) in an ongoing study.
- Iterative consensus-building process for item pool and response scale selection.
Main Results:
- A Table of Specifications (TOS) facilitated consensus on an initial item pool.
- Achieved consensus on 109 items and their response scales for a compassion measure.
- Demonstrated a systematic approach to item generation using a TOS.
Conclusions:
- Systematic item generation guidance, particularly using a TOS, is crucial for measure development.
- Nurses require tools to identify, measure, and enhance compassion in research and practice.
- The developed methods support the creation of reliable and valid instruments for assessing nursing constructs.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
