Continuum of Engagement

View

Explore the continuum of engagement when involving adults with capacity or communication difficulties in research. This section explains how to support and respect individuals’ wishes, recognise different levels of engagement from passive to informed, and create opportunities for participants to express their assent or dissent meaningfully.



Regardless of the individual’s ability for autonomous decision-making, we need to recognise the individual’s:

  • interest in making decisions and acting voluntarily
  • ability to understand and process information relating to these decisions.

We can think about how decision-making may vary over time in relation to the details of any decision and to the individual’s capacity over time, as a continuum of decision-making.

Views and Opinions

  • By ‘supporting’ a decision we mean the actions and/or materials put in place to help the person to understand, retain, weigh up and communicate about the research.
  • By ‘respecting’ a decision we mean adhering to the decision made by the individual.
  • The individual’s wishes and feelings must be considered regardless of their capacity.
  • There is a requirement to be sensitive to the participant’s responses even if consultee advice is that they would want to participate.

Continuum of Decision-Making and Engagement

Passive:

Minimal engagement: no observable or distinguishable response; extreme passivity. This cannot be taken as evidence of agreement to take part

Engaged:

Active engagement; observable and distinguishable response: positive expression of agreement for assent OR negative expression of disagreement for dissent

Informed:

Legal capacity to make an autonomous decision: understand relevant information; retain information; use and weigh up information; communicate decision

Joining efforts with others in order to achieve understanding as far as capacities allow for Active Engagement

Once positive advice from a consultee is in place, the reseacher organises opportunities for the participant to: connect with and recognise the research; to anticipate what the research means to them; and to communicate their engaged assent or dissent in relation to taking part.
