Abstract:
OBJECTIVES -The main objective of this study was to compare the utility, the psychometric properties and the applicability of four pain scales of pain intensity: Faces Pain Scale (FPS), 21 Box-pain Scale (BS-21), Present Pain Intensity (PPI) and Pain Thermometer (TMD) in a sample of older patients, without cognitive impairment or with mild or moderate cognitive impairment. The secondary objectives were: 1) To determinate reliability, construct validity, post-dictive validity and bias of the four scales. 2) To determinate the accuracy that the different scales were performed 3) To determinate the grade of preference of each scale. 4) To determinate what scale presents the best properties to be used with determinates subgroups of older patients with different cognitive levels or age.Material and methods. 121 older patients with chronic pain were recruited from a long term care facilities (mean age: 76.6 years). After verify inclusion criteria, ratings of pain intensity were measured with the four different scales: FPS, BS-21, PPI and TMD. Patients made ratings of current pain two times / day (morning and afternoon) for 7 consecutively days. At the afternoon they also made retrospective daily ratings of maximum, minimum and usual pain. Last day patients also made a retrospective weekly measure.Results.Comparing results of the different pain rating scales, values of BS-21 were more consistent in intra-class reliability and construct validity. Factor analysis of 'pain intensity' construct and correlation coefficients of aggregated and retrospective pain scores are higher with the BS-21. Bias was lower in BS-21 than the other three scales. Results are maintained in both groups of patients, cognitively impaired and unimpaired. In number of errors or grade or preference, FPS o
