Abstract

Introduction:Population health perspectives increasingly focus on people’s perception of resilience, ability to adapt and self-manage. The goal of this study is to determine whether the MijnKwaliteitVanLeven.nl (“MyQualityOfLife.nl”) survey is a valid and reliable instrument for assessing the broader health perspectives at population level.Methods:19,809 entries of the MyQualityOfLife.nl survey were used. To assess face validity, Huber’s six dimensions of positive health were used as a framework for expert feedback. A confirmative factor analyses was done using the expert’s item clustering, followed by data-driven explorative factor analyses and reliability tests.Results:Experts distributed 74 of the 118 items over all six dimensions of positive health. The confirmatory factor analysis model based on expert classification was not confirmed. The subsequent exploratory factor analysis excluded most items based on factor loading and suggested two factors; ‘quality of life’ and ‘daily functioning’, both showing excellent reliability.Conclusion:The MyQualityOfLife.nl survey can assess the broader concept of health in a population as well as ‘quality of life’ and ‘daily functioning’. However, the survey can currently not evaluate several of the positive health dimensions separately. Further research is needed to determine whether this is due to the instrument or the positive health dimensions.

Highlights

Population health perspectives increasingly focus on people’s perception of resilience, ability to adapt and self-manage
This study showed that face validity based on expert feedback was good as items covered all six dimensions of positive health, response dispersions were adequate and reliability of the found factors was high
The MyQualityOfLife.nl survey can be used to assess the broader concept of health in a population as well as the more specific ‘quality of life’ and ‘daily functioning’

Summary

Introduction

Population health perspectives increasingly focus on people’s perception of resilience, ability to adapt and self-manage. The goal of this study is to determine whether the MijnKwaliteitVanLeven.nl (“MyQualityOfLife.nl”) survey is a valid and reliable instrument for assessing the broader health perspectives at population level. Conclusion: The MyQualityOfLife.nl survey can assess the broader concept of health in a population as well as ‘quality of life’ and ‘daily functioning’. § Zuyd University of Applied Sciences, Research Centre for Technology in Care, NL gaps that go outside healthcare [6, 7] These new integrated care policies have to be evaluated to determine if they have the desired impact and instruments are needed that adjust for the population focus as well as the concept of population health.
