Cross-cultural considerations when motivating
older adults to engage in physical activity: do
adaptations need to be made in existing theories
to maximize their effectiveness in multi-ethnic
societies?

Points to Make
Why theory?
Which theories …and when to integrate
Measurement considerations
Multi-methods a necessity
Promoting involvement and ownership
Weave in…what we have done/are doing
in our PA promotion work
An interesting challenge – analysing cross
cultural data…how do we incorporate ‘culture’?

Why Theory?

• Guidelines/strategies for designing
interventions: What should contribute to
sustained PA/reduced ST in older adults?
• Ways of testing the fidelity of the intervention
What theory should provide

Regarding PA/ST intervention trials,
motivational/behavioural change processes
predicting differential adherence to/attrition
in the intervention
What theory should provide

Elucidates processes (the how) by which interventions targeting environmental or individual difference factors may impact targeted outcomes; Are observed behavioural changes mediated by motivational processes proposed by theory?

• Sub-groups analyses – effective for whom,
when, where?
What theory should provide

• What to measure (outcomes, processes,
potential moderators) and how?
What theory should provide

conceptual sense!

Measurement Issues
• Translation… backwards, forwards
• Many types of equivalence to demonstrate
• Was the measure developed for this
particular population? – if no, start from
scratch or revise as needed and
demonstrate validity and reliability
• ‘Think aloud’ method
• Statistical tests of measurement invariance

differences’ in our behavioural change
trials
