This study evaluated a new six-point ordinal scale for measuring pain intensity. Seventy-two participants aged between 23 and 87 years rated the intensity of 'present pain' as well as remembered episodes of 'severe' and 'mild' pain on the scale of pain intensity (SPIN), a 10 cm visual analogue scale (VAS) and a 0-10 numeric scale, in random order. Retesting followed an intervening assessment. ⋯ Some found numbers easier to use whereas others found the SPIN more helpful. We conclude that the SPIN provides a valid measure of pain intensity in patients fully able to communicate their views and experiences. Investigation in patients with cognitive or communication impairments is now required.
