Abstract

Aim: To develop and psychometrically test the Self-Management Assessment Scale (SMASc), a screening instrument for person-centred guidance and self-management support of persons with type 2 diabetes (T2D).

Background: T2D is a common and globally increasing chronic condition. Improved self-management is a vital and integral component of diabetes care to prevent complications from poorly managed diabetes. For diabetes nurses to better understand persons with diabetes experienced challenges and needs regarding self-management and further for persons with T2D to take an active role in managing their condition, an instrument measuring this is needed.

Design: Instrument development and psychometric testing of the content and construct validity, factor structure and reliability.

Method: The SMASc was psychometric tested on a sample of participants (September 2017-November 2017) with a confirmed diagnosis of T2D (N = 104).

Results: Psychometric findings were satisfactory and supported the scale´s reliability. Cronbach's alpha, CVI and goodness-of-fit were acceptable.

Conclusion: Self-Management Assessment Scale is a short validated screening instrument, which can indicate possible barriers for self-management that ought to be approached during the conversation between the person with T2D and the primary healthcare nurses. Therefore, it is a promising instrument to be used to facilitate person-centred guidance and to improve self-management of people living with T2D.
