This single-item measure asks participants to describe their change in pain on a 7-point rating scale with the following options: "very much improved," "much improved," "minimally improved," "no change," "minimally worse," "much worse," and "very much worse".
The distributions of the assessments (very much improved, much improved, minimal improvement or same/worse), were similar between physicians and patients, and in agreement 70.3% of the time; physician-patient agreement was higher in Turkey than in Sweden (73% vs. 61%, p = 0.040).
The CGI-I measures overall improvement on a 4 grade scale: "very much improved", "much improved", "minimally improved" or "no change".
Response choices include very much improved, much improved, minimally improved, no change, minimally worse, much worse, and very much worse.
The illness is compared to change over time and rated as: very much improved, much improved, minimally improved, no change, minimally worse, much worse, or very much worse.
Patient Global Impression of Change (PGIC) was measured on a seven-point ordinal Likert scale at the 12-month time-point only (Very much improved, Much improved, Minimally improved, No change, Minimally worse, Much worse, Very much worse).
The rating categories were "worse," "no change," "improved," "much improved," and "very much improved".
It also suggested that responses in Patient Global Impression of Change of minimally improved, much improved, and very much improved would also constitute minimally important, moderately important, and substantial improvements.
The original response format for the CGIi is: 0 "Not assessed", 1 "Very much improved", 2 "Much improved", 3 "Minimally improved", 4 "No change", 5 "Minimally worse", 6 "Much worse", 7 "Very much worse".
We considered patients choosing response option 1 2 ("very much improved" and "much improved") on the GPE-scale as "importantly improved" and those choosing option 3 5 ("a little improved", "no change" and "a little deterioration") as "stable".
"I've gone through so much and learned so much and improved so much.
