Conclusion
Through the extensive work put into this study, an adherence assessment tool for asthmatic patients was developed. The AAMQ-13 has a high internal validity, good criterion validity, and strong construct validity. All of these findings suggest that the AAMQ-13 is a promising tool for future use as an adherence assessment questionnaire in asthmatic patients. From a clinical perspective, uncontrolled asthma requires long-term adherence to the medications and the treatment plan; thus, a short, brief, feasible, reliable, and valid measure of patient adherence is needed which can be used in all medical practice conditions. Moreover, most of the questionnaires available up to date can only identify non-adherent patients. The AAMQ-13 is the only questionnaire that was specifically designed and validated in the Middle East to assess asthmatic patient adherence to their medications and predict patients’ patterns of non-adherence. It can also predict other important outcomes; as a significant correlation was found between the AAMQ-13 and ACT, and PHBS questionnaires, so it can give an indication whether the patient’s asthma symptoms are controlled and it gives an insight about the patient’s lifestyle.
