Stanford Spanish HAQ 8-Item Disability Scale
Por favor marque la respuesta que mejor describa sus habilidades usuales (comunes) durante la semana pasada.
Score the number circled for each item. If more than one consecutive number is circled for one item, code the higher number (more difficulty). If responses are not consecutive, code as blank. The disability index is the mean of the eight items. If more than 2 items are blank, do not score the index.
Tested on 272 Spanish-speaking subjects with arthritis. N=25 for test-retest.
Source of Psychometric Data
The Stanford Spanish Arthritis Self-Management Study (Programa de Manejo Personal de la Artritis). The psychometrics were done on the original 20-item Spanish scale, resulting in this version. Psychometrics reported in: González V, Stewart A, Ritter P, Lorig K, Translation and validation of arthritis outcome measures into Spanish. Arthritis and Rheumatism, 38(10),1995, pp.1429-1446.
This is a modified version of the 20-item Spanish disability scale which we translated and back translated from the Stanford Health Assessment Questionnaire. We have replaced the numbers with check boxes on the print version. It should be noted that the items have been chosen as they represent use of every major joint in the body. While closely related to an ADL scale this is not an ADL scale but rather a disability scale.
