Correlations of coefficient inter-reliability were 0.82 and intra-reliability 0.65 for the overall scores. The contents validity of the three factor structure was established; in construct validity met a slight difference between acute and chronic patients in activity with statistically and clinically significant (p\<0.05). On evaluation of the concurrent validity of the SGRQ and the score of physical function (-0.67), vitality (-0.51) and social function (-0.46) of SF36 good correlations were found. The responsiveness showed statistical differences (p\<0.05) with the scores being lesser in the second measurement (better quality of life).Conclutions: SGRQ version for acute and chronic patients in Colombia is psycometrically equivalent to the original version, reliable, valid and could be used in our country and Spanish speaking countries with similar etnic, cultural and social conditions.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/40/Suppl_56/P3973}, eprint = {https://erj.ersjournals.com/content/40/Suppl_56/P3973.full.pdf}, journal = {European Respiratory Journal} }
