The measurement of physical activity (PA) and sedentary behaviour (SB) is fundamental to health-related research, policy, and practice but there are well-known challenges to these measurements. Within the academic literature, the terms “validity” and “reliability” are frequently used when discussing PA and SB measurement to reassure the reader that they can trust the evidence.


In this webinar, Dr Paul Kelly will argue that a lack of consensus about the best way to define, assess, or utilise the concepts of validity and reliability has led to inconsistencies and confusion within the PA and SB evidence base.



Learning outcomes

  • Appreciate the difference and similarities of validity and reliability
  • Explain why miss-use of these terms has been detrimental to the evidence base
  • Consider better use of these terms, for better evidence generation
