“…8 Factor analysis of those beliefs that had the highest correlations with inhaler use was then performed and 33 items selected. 9 A 66-item questionnaire was completed by 335 asthma patients from seven general practices in Norfolk. They rated the 33 items on a five-point scale first in relation to beclomethasone and then in relation to salbutamol.…”

“…Such a questionnaire is being developed and this paper describes its further refinement, including an examination of the validity and reliability of its sub-scales. [8][9][10] Other questionnaires have been developed to assess adherence to asthma treatments. Brooks et al devised a five-item scale that had moderate internal reliability with Cronbach's alpha coefficients of 0.67, 0.75 and 0.68 in their analyses.…”

To develop a valid and reliable questionnaire for measuring patients' beliefs about inhaler treatments for asthma. Methods: In seven general practices, 335 patients prescribed both beclomethasone and salbutamol inhalers completed a 66-item questionnaire. Subscales were developed using factor analysis and a 29-item questionnaire sent to 90 patients in another practice to estimate test-retest reliability. Results: Three factors explained 31.4% of the variance relating to beliefs about inhalers: preventing asthma symptoms, problems with and concerns about inhalers, and relieving asthma symptoms. Cronbach's alpha coefficients of the sub-scales were 0.71, 0.70 and 0.70 respectively. Intra-class correlation coefficients were 0.87 or more for all three sub-scales. The prevention and relief scale scores were significantly correlated with estimates of corticosteroid and β 2-agonist use. Conclusions: A valid and reliable questionnaire has been developed for measuring patients' beliefs about inhaler treatments for asthma. Its utility in predicting adherence and facilitating patient education needs to be tested.

“…The development of the questionnaire from interviews with asthma patients from one general practice in Suffolk has been described. 10 It consists of 33 belief statements rated twice; first in relation to corticosteroid inhalers (preventers) and then to short-acting β2-agonists inhalers (relievers), making 66 items in total. A five-point Likert scale (from strongly disagree to strongly agree) is used.…”

Objective: To measure patients' beliefs about inhaler treatment for asthma. Design: A 66-item questionnaire with 33 statements rated first in relation to corticosteroid inhalers and then to β2-agonists. Subjects: Seven hundred asthma patients prescribed both beclomethasone and salbutamol inhalers from seven general practices in Norfolk. Results: Although 93% of the 335 respondents believed in prevention, 24% wanted to stop their corticosteroid inhaler. Over 95% of patients perceived β2agonists as effective. Half were concerned about sideeffects from both inhalers and two-thirds did not like being dependent on inhalers. More than a third thought that avoiding triggers or relaxing were more effective than taking inhalers. Differences in responses between the inhalers were in the theoretically expected direction. Conclusion: Whilst many patients may well hold beliefs about inhalers that are compatible with the optimal use of inhalers for the treatment of asthma, a significant minority do not.

“…There are currently no validated methods available to systematically assess the beliefs that patients hold about their SABA therapy. Existing measures available focus on either general beliefs about treatment (21) or the illness (22), or on overall asthma inhaler use (23), rather than on beliefs about SABA specifically. The SRQ was developed to fill this gap.…”

Background Patient over-reliance on short-acting beta2 agonists (SABA), with concomitant underuse of inhaled corticosteroids (ICS), is associated with poor asthma control and increased risk of asthma attacks.Objective To develop and validate a brief questionnaire to elicit patients' perceptions of SABA (e.g. belief that asthma is best managed by SABA alone) that could lead them to be overly reliant on SABA. MethodsThe 5-item SABA Reliance Questionnaire (SRQ) was adapted from the well-validated Beliefs about Medicines Questionnaire (BMQ) assessing patient perceptions of the importance of, and necessity for, SABA in managing their asthma. The psychometric properties of the questionnaire were studied using Amazon Mechanical Turk (mTurk), an online survey platform, in 446 people with self-reported asthma. Internal reliability and criterion-related validity were assessed based on relationships between SRQ scores and other variables, including self-reported adherence to ICS and perceived importance of reliever inhalers. ResultsInternal reliability was good with Cronbach's α = 0.74. Criterion-related validity was demonstrated by inverse correlation between SRQ scores and self-reported adherence to ICS (r = −0.291, p<0.0001), and significant correlation between SRQ scores and perceived reliever importance (r = 0.216, p<0.0001), as well as by significant differences in SRQ scores between those with high vs. low self-reported ICS adherence (adherence to ICS t = 4.825, p<0.0001). ConclusionsThe SRQ demonstrated acceptable internal reliability, and criterion validity, supporting its potential utility as a pragmatic tool for identifying patients whose beliefs are indicative of over-reliance on SABA for asthma.
