A new self-completion outcome measure for diabetes : is it responsive to change ?
Self-completion instruments assessing subjective health are increasingly being used to measure patient outcome.
However, there is very little evidence as yet of existing instruments'responsiveness to change.
This paper describes a study to evaluate the responsiveness to change of a self-completion instrument for the measurement of clinical outcome in patients with diabetes.
A prospective follow-up study of 48 patients with non-insulin-dependent diabetes commencing insulin therapy was carried out, whith assessments at baseline (i.e. pre-intervention), 6 weeks and 3 months post-intervention.
The outcome measures used were the changes in scores on the self-completion instrument for symptom level, physical function, energy, depression, psychological distress and barriers to activity, HbA1C, non-fasting serum cholesterol and the body mass index (BMI).
There were significant improvements in HbA1C and non-fasting serum cholesterol and worsening of the BMI, as expected.
The self-completion instrument detected significant improvements in patient-reported symptoms within 6 weeks of the intervention (p<0.01) and in energy levels (p<0.05).
There is evidence from this study of the self-completion instrument's ability to respond to change and it has potential for use in evaluative studies.
