Title: Health Locus of Control and Health related Quality of Life in Patients with Inflammatory Bowel disea


1
Health Locus of Control and Health related
Quality of Life in Patients with Inflammatory
Bowel disease
  • Sheila Mair
  • Gastroenterology Nurse Practitioner

2
  • Background
  • Study
  • design
  • Instruments
  • Findings
  • Implications

3
IBD
4
IBD
Diarrhoea, abdominal pain, weight loss, tiredness
5
Treatment
  • Dietary
  • Surgery
  • Pharmacological
  • 5ASAs, immunomodulators, steroids, biologicals

Compliance/concordance
6
Treatment
7
Locus of control
  • Developed by Wallston based on social learning
    theory
  • Health behaviours could be predicted by the
    extent to which an individual believes in an
    internal locus of control over health.

8
Questions
If QoL improves with successful therapy and
successful therapy is related to ability to
control disease then ability to control disease
may influence QoL.
9
Aim
  • To explore the relationship between health
    related quality of life and health locus of
    control

Health related Quality of Life
Health Locus of Control
10
Instruments
  • Self-completed postal questionnaires
  • IBDQ
  • Health related Quality of life
  • Bowel, systemic, emotional, social
  • (Guyatt et al, 1989)
  • MHLOC
  • Multidimensional Health Locus of Control
  • Internal, chance, doctors, others
  • (Wallston et al, 1994)

11
Sample
  • Sample of convenience
  • Data base of patients of one consultant
    gastroenterologist at district general hospital
  • 198 questionnaires sent out
  • 96 returned 48 response rate
  • 3 returned incomplete

12
The Numbers Stuff!
  • SPSS
  • Statistical sig plt0.05
  • Spearmanss Rank Correlation
  • Variables ranked, linear relationship between 2
    sets of data measured
  • Bonferroni correction for multiple significance
    testing

13
Null hypothesis
  • There is no relationship between QoL and Health
    Locus of control
  • Outcome measure- internal locus of control
  • Secondary outcome measures- relationship between
    IBDQ scores and MHLC parameters.

15
Findings
  • Statistically significant but weak (0.24) between
    IBDQ (total) and MHLoC internal
  • Separate analysis suggests only applies to UC

16
Discussion
  • Sample size
  • Representative
  • Differences between Crohns and UC

17
Implications
  • Now increased understanding of locus of control
    ? tailored support
  • Future research into relationship between
    concordance, locus of control and quality of life
