Delphi Procedure for Taxonomy Development
Objective: To develop a method of specifying content of behaviour change interventions in terms of component behaviour change techniques and to achieve multidisciplinary and international acceptance for future development
Protocol Steps
Delphi Procedure with Expert Panel
Conducted an iterative process of revisions and consultation with 41 international experts to develop the behaviour change technique taxonomy
Note: This was the primary method for taxonomy development involving multiple rounds of expert consultation

“Development of the taxonomy involved a Delphi procedure, an iterative process of revisions and consultation with 41 international experts”
Hierarchical Structure Development
Developed hierarchical structure of the taxonomy list using inductive 'bottom-up' and theory-driven 'top-down' open-sort procedures with 36 participants
Note: Both bottom-up and top-down approaches were used to organize the BCTs into groupings

“hierarchical structure of the list was developed using inductive 'bottom-up' and theory-driven 'top-down' open-sort procedures (n = 36)”
Training in Taxonomy Use
Provided training in use of the taxonomy through 1-day workshops and distance group tutorials with 161 participants
Note: Training methods were evaluated by changes in intercoder reliability and validity (agreement with expert consensus)

“training in use of the taxonomy (1-day workshops and distance group tutorials) (n = 161) was evaluated by changes in intercoder reliability and validity”
Evaluate Taxonomy for Coding Interventions
Assessed the taxonomy for coding interventions by evaluating reliability (intercoder; test-retest) and validity with 40 trained coders
Note: Reliability and validity measures were used to assess coding performance

“evaluating the taxonomy for coding interventions was assessed by reliability (intercoder; test-retest) and validity (n = 40 trained coders)”
Evaluate Taxonomy for Writing Descriptions
Assessed the taxonomy for writing descriptions by evaluating reliability (intercoder; test-retest) and by experimentally testing its value with 190 participants
Note: Both reliability measures and experimental testing were conducted
