Table 2. Two-month within- and between-group changes in asthma knowledge, decisional conflict, appropriate use of pharmacotherapy and asthma control (N = 51).
| Within-group change | Between-group change | ||||
|---|---|---|---|---|---|
| MD [95% CI] | P valuea | MD [95% CI] | P valueb | ||
| Knowledge of asthma (QCALF score: a higher score is better) | Education + DA, n = 26 | 3.51 [1.74–5.3] | 0.0002 | 1.50 [-1.03–4.0] | 0.24 |
| Education alone, n = 25 | 2.02 [0.21–3.8] | 0.03 | |||
| Decisional conflictc (DCS score: a lower score is better) | Education + DA, n = 26 | -2.93 [-5.38–-1.60] | 0.0073 | -1.25 [-2.97–1.90] | 0.68 |
| Education alone, n = 25 | -2.35 [-4.36–-1.27] | 0.0093 | |||
| Asthma control (ACSS score: a higher score is better) | Education + DA, n = 26 | 8.47 [2.51–14.4] | 0.0063 | -0.79 [-9.31–7.7] | 0.85 |
| Education alone, n = 25 | 9.26 [3.17–15.3] | 0.0036 | |||
| PR [95% CI] | P valuea | PR [95% CI] | P valueb | ||
| Appropriate use of pharmacotherapy | Education + DA, n = 26 | 1.35 [0.80–2.27] | 0.25 | 0.81 [0.34–1.90] | 0.62 |
| Education alone, n = 25 | 1.67 [0.84–3.30] | 0.14 | |||
ACSS: Asthma Control Scoring System; CI: Confidence interval; DCS: Decisional Conflict Scale; MD: Mean difference; PR: Prevalence ratio; QCALF: Questionnaire de connaissances sur l’asthme de langue française.
aWe assessed whether changes in QCALF scores, DCS scores, ACSS scores, and in the proportions of appropriate users were different over time within each group.
bWe assessed whether or not within-group changes in QCALF scores, DCS scores, ACSS scores, and proportions of appropriate users over time were different between groups.
cDCS scores underwent a natural log transformation. To facilitate interpretation, differences in means and their 95% CI were back-transformed on their original scale.
