Abstract

Aim: This study contributes to the accuracy of the Quality of Life (QoL)
measurement in people with intellectual disabilities (ID) by exploring the
content and face validity of the different angular points (client, family, caregiver)
with the use of selected existing measurement instruments. Methods: First,
literature and an expert meeting were used to identify QoL instruments used in
the Netherlands. Domains covered by these instruments were compared with
domains from the WHO QoL framework. Second, data was collected by means
of interviews. Participants were: 6 clients with mild to moderate ID, and
complemented each with a family member and their professional caregiver.
Participants were recruited through care provider ‘s Heeren Loo. Interviews
were done with a carefully designed interviewguide. Participants were asked
about the importance of QoL domains and individual items for QoL for the person with ID. The interviews were analyzed using content and domain
analysis taking into account that client, family and caregiver were talking about
the same client. Recruitment started May 2013. Interviews took place in May –
June 2013. Results: Different QoL measurement instruments are used in the
Netherlands. Most of these are based on Schalock’s work and include the
domains: interpersonal relations, social inclusion, personal devolopment,
physical wellbeing, self-dertermination, material wellbeing, emotional wellbeing,
rigths and religion. Religion is part of the WHO framework but not of
Schalock’s. Conclusion: Despite the paradigm that QoL for people with ID
ought not differ from that of the general Dutch population, not all domains from
the WHO QoL-framework and the Schalock QoL framework were covered in the
QoL instruments used for people with ID. The combination of literature study
and interviews suggest the content validity of currently used QoL instruments
might be limited. The interviews in this study will help to further investigate the
face validity of items included in QoL instruments.
