Background: Patient activation is a major driver of self-management behaviours. T2DM clinical outcomes are responsive to changes in scores. This study aims to identify the minimum clinically important difference (MCID) of the Patient Activation Measure (PAM) for T2DM self-management outcomes in primary care settings.
Method: This is cross sectional study. A self-administered questionnaire and clinical data extraction were used for data collection.
Results: A total of 347 T2DM patients participated in the study. Most of the participants (53.6%) were passive (level 1) and only 6.3% were highly activated (level 4). Logistic regression analysis indicated that for an additional score increase in the PAM scale, the odds of improving diabetes clinical outcomes improved by 6-10%. The MCID of the PAM score ranged from 6.2 to 14.4 points.
Discussion: This study finding suggests that achieving a clinically and behaviourally significant difference in T2DM self-management outcomes requires improving at least one level across the PAM levels ranging from level 1 to level 4.
Implications for practice: Primary care is a key setting for T2DM self-management and the PAM is a reliable indicator of T2DM self-management outcomes. Our finding suggest that the PAM can be used to achieve clinically significant improvement in T2DM clinical outcomes in GP setting. The PAM is user-friendly and can be used very easily by GPs or PNs during the patient visit.
