Patient Global Impression of Change (PGIC) / Global Rating of Change (GRC)
Link
- Access examples of the Patient Global Impression of Change (PGIC) / Global Rating of Change (GRC)
Type
- Evaluative
Description
- Reviews the patient’s impression of progress they’ve made with treatment. See Kamper, Maher and Mackay (2009).
Advantages
- Simple to understand.
- No scoring required.
- A horizontal 7 point scale has good clinimetric properties.
Precautions or limitations
- The wording that introduces the scale needs to be carefully considered to get an unambiguous response. Possible wording: very much better, better, slightly better, the same, slightly worse, worse, very much worse. For the midpoint, wording could be "unchanged" with end points spelt out in words and numbers or marks.
- The scale should be used along with at least one standardised outcome measure.
Patient Specific Functional Scale (PSFS)
Link
Type
- Evaluative
Description
- Measures change in functional activities specifically relevant to individual clients.
Advantages
- Useful for clients with very specific functional needs or goals.
- Keeps treatment goal oriented.
- Works well when it’s difficult to measure progress using standardised outcome measures (e.g. English language literacy issues) or the client has a condition that doesn't fit well with available outcome measures.
- Can supplement standardised outcome measures and add an individualised aspect that can more fully engage clients with their own progress.
Precautions or limitations
- If the functional activities chosen vary widely with respect to how likely/quickly they are to be achieved, the scoring will be affected.
- Should be used along with other standardised outcome measures.
