Phase four: Psychometric analysis (Reliability and Validity).
In this phase, 213 participants with asthma completed four questionnaires (AAMQ-13, TAI, ACT®, and PHBS) (28–30). Their age ranged from 18 to 84 years with a mean age of 36.9 years (SD= 13.62). The majority were females (n= 149, 70%), living in Amman (n= 174, 81.7%), married (n= 128, 60.1%), had a bachelor’s degree (n= 158, 74.2%), employed (n= 97, 45.5%), and mainly non-smokers (n= 147, 69%) as shown in Table III.
No correlation was found between the participants’ age and the total score of the AAMQ-13. No statistically significant difference was found between gender, living place, marital status, education, employment, smoking and the adherence level of the participants.
