Crohn’s Life Impact Questionnaire (CLIQ)

Need for CLIQ
• No PROM available specific to CD
• No IBD PROM truly patient-based
• No IBD PROM employs modern psychometric
methods
• To allow impact of CD to be compared to that of
different diseases

Requirements for CLIQ
• To have a coherent measurement model
• Derive content directly from patients through
unstructured qualitative interviews
• Unidimensional scale(s) providing valid total scores
• Reproducible and valid
• Short, simple to administer and score

Needs-based QoL model
• Impact of disease related to inability to meet needs
rather than functional limitations
• Life gains its quality from the ability and capacity of
individuals to satisfy their needs
• QoL is a unidimensional construct - providing an
index rather than a profile

Objective
Employment-related needs
Function Needs fulfilled

Development
Project conducted by Galen Research and MRI.
Part-funded by CCUK who also provided some patients.
• 30 qualitative interviews with CD patients
• Thematic content analysis of transcripts
• 15 cognitive interviews to confirm face and content
validity
• Test-retest validation survey with 273 CD patients
• Identification of final scales
• 15 interviews to re-confirm face and content validity

Results
• 27-item QoL scale identified
• QoL scale proved to be unidimensional
• Reproducible (test-retest correlations = 0.91)
• High correlation between CLIQ QoL scores and
fatigue (U-FIS), 0.79
• 2-3 minutes to complete

Sample QoL items
There is not much fun in my life
I feel dependent on others
I rarely feel clean
I worry about having an accident
I only feel comfortable at home

Scoring
QoL Scale
• “True” response scored 1, “Not true” scored 0
• Item scores summed to give total score
• High score indicates poor QoL

Patient quotes
“If I had to explain to my doctors what I was going
through I’d take it [the CLIQ] with me… welcome to
my world!!”
“I feel like I wrote this questionnaire, I no longer feel
alone”

Potential uses of CLIQ
• Routine clinical practice
• Clinical studies and trials
• Audit
• Economic analysis
• CLIQ adds to growing battery of nQoL measures
linked by co-calibration
