IntroductionIntroduction
Need for assessment & research tools for this group of children
Existing quality of life tools
Significance of this tool
Why parents’ perspective?
![Page 7: Quality Of Life for Children with Disabilities: From Conceptual Model to Measurement Instrument Rebecca Renwick, PhD Rebecca Renwick, PhD Ann Fudge Schormans,](https://reader036.fdocuments.in/reader036/viewer/2022062321/56649e055503460f94af11a5/html5/thumbnails/7.jpg)
Conceptual Framework Conceptual Framework for Instrumentfor 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/intellectual 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
![Page 8: Quality Of Life for Children with Disabilities: From Conceptual Model to Measurement Instrument Rebecca Renwick, PhD Rebecca Renwick, PhD Ann Fudge Schormans,](https://reader036.fdocuments.in/reader036/viewer/2022062321/56649e055503460f94af11a5/html5/thumbnails/8.jpg)
Conceptual FrameworkConceptual FrameworkAssumptionsAssumptions about Quality of Life 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
Child’s & family’s quality of life interconnected
Child’s quality of life dependent on others in her/his life
![Page 9: Quality Of Life for Children with Disabilities: From Conceptual Model to Measurement Instrument Rebecca Renwick, PhD Rebecca Renwick, PhD Ann Fudge Schormans,](https://reader036.fdocuments.in/reader036/viewer/2022062321/56649e055503460f94af11a5/html5/thumbnails/9.jpg)
Conceptual FrameworkConceptual FrameworkMajor Elements of Quality of LifeMajor 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 LifePoorer Fit = Poorer Quality of Life
