PURPOSE: Asthma Control Test (ACT) has been devised to assess the degree of asthma control in out-patients setting. The aim of this study is to validate the Arabic version of ACT.

METHODS: Asthma patients completed the Arabic version of ACT during regular visit to one of two asthma specialists. A spirometry was obtained and the asthma specialist assigned rating for asthma control using a 5-point rating scale and indicated modification in management as step up, same or step down of asthma treatment. Statistical analysis included: Spearman's correlation coefficient, ANOVA testing, internal consistency reliability, logistic regression methods and receiver operating characteristics (ROC) curves. Comparison is made to the initial work for the development of ACT by Nathan RA et al (J Allergy Clin Immunol 2004;113:59–65).

RESULTS: 40 patients completed the study, the mean age was 32.6+14.0 years, mean FEV1 was 2.7 + 1.0 L (89.2% + 23.6% of predicted). The mean ACT score was 15.9+5.8; mean of specialist asthma control rating was 3.4+1.0. The internal consistency reliability of the 5-item ACT survey was Alpha=0.92. The correlation was moderate between ACT and specialists rating (r=0.482, p=0.002) as well as between ACT and treatment modification (r= −0.350, p=0.027). The correlation between FEV1 and ACT was low and didn’t reach significance (r=0.185, p=0.259). ACT distinguished between patients with different specialist rating (F=3.37, p=0.02) and the need to change therapy (F=3.62, p=0.037). The areas under ROC for ACT, FEV1, and ACT and FEV1 as independent variables were 0.720, 0.721, and 0.766 respectively. All results were comparable to the initial work for development of ACT except for correlation between ACT and FEV1.

CONCLUSION: The Arabic version of the ACT is a valid tool to assess asthma control. ACT correlates better with asthma specialist rating of asthma control than with FEV1.

CLINICAL IMPLICATIONS: The Arabic ACT can be used to assess asthma control in Arabic native language patients.
