Introduction
  • Need for assessment research tools for this
    group of children
  • Existing quality of life tools
  • Significance of this tool
  • Why parents perspective?

7
Conceptual Framework for Instrument
  • Research team included parents of children with
    developmental/ intellectual disabilities (ID/DD)
  • Conceptual framework based on in-depth interviews
    with 30 birth, adoptive, foster parents,
    kinship carers
  • Focused on children with developmental/intellectua
    l disabilities (ID/DD), aged 3 to 12 years
  • Developed from qualitative analysis of interview
    data (modified grounded theory methodology)
  • Member checking and verification of major
    concepts and themes emerging form analysis

8
Conceptual FrameworkAssumptions about Quality of
Life
  • Holistic concept with many dimensions
  • Both a dynamic process an outcome
  • Can change over time
  • Same domains for children from 3 to 12 years
  • Childs familys quality of life interconnected
  • Childs quality of life dependent on others in
    her/his life

9
Conceptual FrameworkMajor Elements of Quality of
Life
  • Three elements
  • CHILD, FAMILY, LARGER ENVIRONMENT
  • Quality of life arises from dynamic relationship
    among these three elements
  • Fit among elements determines quality of life
  • Better Fit Better Quality of Life
  • Poorer Fit Poorer Quality of Life

Conceptual FrameworkQuality of Life Domains
Three Major Areas of Life (BBB)
  • BEING
  • Who the child is perceived to be
  • BELONGING
  • Childs connections to people and places
  • BECOMING
  • Childs nurtured growth and development

12
Development of Instrument
  • Conceptual framework reflects parents
    perspective
  • Items include phrases and expressions used by
    parents interviewed
  • Reviewed by parents, professionals, researchers
  • Pilot-tested with parents

13
Description of Instrument
  • Quality of Life Measure for Children with
    Developmental Disabilities Parental Perspective
  • 50 items
  • Focus Three major areas of life (BBB)
  • Interviewer- or self-administered
  • Suitable for phone and personal interviews

14
Sample Items
15
Being Items Who the child is perceived to be
  • Other people treat my child first and foremost as
    a child.
  • Other people treat my child as a child with a
    disability.
  • Other people see only my childs disability.

16
Belonging ItemsChilds connections to people and
places(a) Childs Connections to People
  • My child plays regularly with other children.
  • My child has friends.
  • My child is regularly invited to play with other
    kids.
  • People who understand how my childs disability
    affects my child treat my child better than
    people who do not know about her/his disability.

17
Belonging Items(b) Childs Communication
  • Professionals are able to understand what my
    child says/ communicates.
  • My childs behavior is affected when other people
    dont understand her/his communication (e.g.,
    acts up, becomes quiet etc.)

18
Belonging Items(c) Childs Connections to Places
  • My childs school or day care is set up in ways
    that meet my childs needs. (e.g., the child can
    use the bathroom, access lockers, a time-out is
    available if required, elevators are available if
    needed, etc.)
  • Professional services suitable for my child are
    available to her/him. (e.g., doctors, dentists,
    therapists, etc.)
  • Professional services suitable for my child are
    easily accessible.

19
Belonging Items(d) Childs Safety and Security
  • My child feels secure with certain people s/he
    sees often.
  • My child feels safe playing with other kids.
  • My child avoids doing certain activities because
    s/he doesnt feel safe.

20
Becoming ItemsChilds Nurtured Growth and
Development
  • Important people in my childs life recognize
    her/his specific needs related to the disability.
  • People in my childs life recognize her/his needs
    related to being a child.
  • Important people in my childs life do the things
    that make my child happy.
  • Peoples expectations match my childs abilities.

21
Becoming Items (Continued)
  • The government is supporting my family in ways
    that help to meet my childs needs.
  • My child is supported to do the important things
    in her/his life to help her/his growth and
    development.
  • My child has opportunities to do
    things/activities in her/his community that are
    meaningful to her/him?
  • My family receives enough support to enable us to
    support my childs growth and development.

22
Three five-point scales
  • How much does this statement apply to your
    childs situation right now?
  • How important is this for your child?
  • How satisfied are you with the way things are?

26
Testing the Instrument
  • Minimum number of participants 180 parents
  • Parents/carers of children with ID/DD, aged 3 to
    12 years
  • Telephone interviews
  • Other measures included in interview
  • socio-demographics
  • function
  • health-related quality of life measures

27
Testing the Instrument
  • Sample Size

Instrument Properties (1)
  • Face Validity
  • Item development approach
  • Systematic review by parents, professionals,
    researchers of item relevance and
    appropriateness.
  • High level of agreement
  • Content Validity
  • Systematic review by parents, professionals,
    researchers to relate items to conceptual model
  • High level of agreement

31
Instrument Properties (2)
  • Internal Reliability
  • Cronbachs reliability analysis
  • Most coefficients above .70
  • Concurrent Validity
  • Correlations with other measures of health
    function
  • Some overlap but assesses something different
  • Construct Validity
  • Factor analysis
  • Supports domains
  • Some item realignments and exclusions
