Results reliability Results validity
(CrV) Concurrent validity:
Comparison of pain ratings by the observer’s assessment and the faces pain
scale showed a high correlation (r = 0.76, p < 0.0001). The correlation
between the nurses’ observations and the faces scale was significant in both
hospital populations (r = 0.81, p < 0.0001 in Cape Town, and r = 0.53, p <
0.0001 in Durban).
(Sen) At the first analgesic administration, the median face score was 5 (2–6).
After analgesic administration the median score was 1 (1–6) (p < 0.0001). The
proportion of patients with pain scores above 2 was 66 of 77 (86%) before
treatment. This proportion was significantly different compared with before and
after treatment (p < 0.001). Also in the youngest children aged 4–5 years, the
proportion of patients with pain scores >2 decreased from 83% to 33% after
administration of analgesics (p < 0.001).
(CrV) Concurrent validity:
A strong positive correlation (r = 0.93, p < 0.001) was found between the
ratings of pain intensity on the VAS and FPS-R.
Commentary
The psychometric scale
evaluation was conducted using
an experimental pain stimulus
instead of using clinical pain
stimili.
