評估工具評值標準

Scientific Advisory Committee of the Medical Outcomes Trust (SACMOT)於2002年列出以下八項評價 health status 與 quality-of-life相關評估工具好壞之標準，可做為我未來評斷評估工具之參考：
1. Conceptual and measurement model: the rationale for and description of the concept and the populations that a measure is intended to assess and the relationship between these concepts.

2. Reliability: the degree to which an instrument is free from random error.
- Internal consistency: the precision of a scale, based on the homogeneity (intercorrelations) of the scale’s items at one point in time.
- Reproducibility: stability of an instrument over time (test–retest) and inter-rater agreement at one point in time.

3. Validity: the degree to which the instrument measures what it purports to measure.
- Content-related: evidence that the domain of an instrument is appropriate relative to its intended use.
- Construct-related: evidence that supports a proposed interpretation of scores based on theoretical implications associated with the constructs being measured.
- Criterion-related: evidence that shows the extent to which scores of the instrument are related to a criterion measure.

4. Responsiveness: an instrument’s ability to detect change over time.

5. Interpretability: the degree to which one can assign easily understood meaning to an instrument’s quantitative scores.

6. Burden: the time, effort, and other demands placed on those to whom the instrument is administered (respondent burden) or on those who administer the instrument (administrative burden).

7. Alternatives modes of administration: these include self-report, interviewer-administered, trained observer rating, computer-assisted interviewer-administered, performance-based measures.

8. Cultural and language adaptations or translations: involves two primary steps: (1) Assessment of conceptual and linguistic equivalence; (2) Evaluation of measurement properties.
