Development and validation of an observational instrument for the assessment of well-being in people with dementia from the perspective of person-centered care: List of Well-Being Indicators.

In the context of the person-centered care model, the creation and validation of an observational instrument for the assessment of well-being in people with dementia is presented, from a perspective that aims to highlight the effects that the physical and social environment have on the person, and how they are reflected in their well-being.

The List of Indicators of Well-Being (LIBE) was created following an iterative inductive process with professionals from different disciplines, until reaching the validated version. It was validated in two successive studies with a sample of 79 people with dementia. Analyses of discriminatory ability of the indicators that make up the scale, internal consistency, inter-rater reliability, and convergent and discriminant validity were performed.

LIBE offers an observational measure of behaviors considered indicators of well-being in people with dementia living in residential facilities. It is a valid and reliable instrument, which offers a different perspective of measuring a construct little explored in populations with dementia. It is an instrument easy to apply, with different uses (clinical, intervention, research), and applicable by professionals from different disciplines.

This article explains the process of creation and psychometric validation of the scale.
