Development and Preliminary Validation of the Adult Asthma Adherence QuestionnaireTM

Utilization and Costs of Severe Uncontrolled Asthma in a Managed-Care Setting

“…Using the recent validated Adult Asthma Adherence Questionnaire that identifies barriers to adherence, outreach programs directed at individual patients with SUA could administer, evaluate, and act on the identified barriers to improve adherence. 29 The suboptimal asthma outcomes of patients with SUA observed in this MCO were also found in other medical care settings. [30][31][32] The present study noted that the management of patients with SUA could be enhanced by the institution of higher step-level care as recommended by asthma guidelines.…”

Asthma inhaler adherence determinants in adults: systematic review of observational data

“…Adherence was related to higher income in three out of eight reported results [34,40,[53][54][55][57][58][59]; more prescription coverage in one out of four results [34,40,45,59]; lower treatment costs in two out of seven results [47,54,55,61,77]; and lower perceptions of social norms in one out of three results [68,72,77]. Several other variables were identified in fewer than three results and were found to be unrelated to adherence: geographical area [47]; urban location [59]; immigration status [52]; crime rate in area of residence [54]; social modelling [68]; and social support [40,68].…”

“…Stronger beliefs in the necessity of using inhalers were associated with better adherence in 14 out of 16 results [38,40,53,60,61,65,69,74,77,82], beliefs in their effectiveness in four out of seven results [35,40,52,53,77], and more broadly-framed positive beliefs in inhaler usefulness or benefits in one out of three results [34]. Having fewer concerns about medication was related to better adherence in nine out of 17 results [38,40,60,64,65,68,72,74], lower perceived side-effects in two out of four results [72,77], lower beliefs that medication in general is overused in one out of three results [60,77], and stronger beliefs in inhaler necessity relative to concerns in two out of three results [68,69,72]. Readiness to use inhalers showed positive associations to adherence in three results [37,61], indicators of self-efficacy in four out of nine results [32,35,40,57,65,68], and stronger adherence routines in three results [53,68,72].…”

“…Asthma knowledge was found to be unrelated to adherence [32,53], while medication knowledge was reported to be related to adherence in only one out of five results [34,40,61,77] The role of treatment beliefs was studied extensively. Stronger beliefs in the necessity of using inhalers were associated with better adherence in 14 out of 16 results [38,40,53,60,61,65,69,74,77,82], beliefs in their effectiveness in four out of seven results [35,40,52,53,77], and more broadly-framed positive beliefs in inhaler usefulness or benefits in one out of three results [34].…”
