Developing a Nomenclature for Behaviour Change Interventions (original) (raw)

Background: To increase effective implementation and replication of behaviour change interventions, behavioural medicine needs to improve methods of specifying and reporting ‘active ingredients’. An on-going internationally supported project has developed a hierarchically structured taxonomy of behaviour change techniques (BCTs). This study aimed to test its reliability. Methods: In round one, five researchers coded 45 intervention descriptions by BCTs. Discrepancies were used to refine the taxonomy. Reliability of the refined taxonomy was assessed by six researchers coding 40 descriptions. In both rounds, each description was coded independently by two researchers. Descriptions were selected using quota sampling of articles published 2009-2010 in three international journals that represented a spread of interventions addressing prevention, illness management and health professional behaviours. Agreement by BCT was assessed by adjusted Kappa for BCTs observed more than five times. R...
Reliability of Identification of Behavior Change Techniques in Intervention Descriptions
Annals of behavioral medicine : a publication of the Society of Behavioral Medicine, 2015
The aim of this paper is to assess the frequency of identification as well as the inter-coder and test-retest reliability of identification of behavior change techniques (BCTs) in written intervention descriptions. Forty trained coders applied the "Behavior Change Technique Taxonomy version 1" (BCTTv1) to 40 intervention descriptions published in protocols and repeated this 1 month later. Eighty of 93 defined BCTs were identified by at least one trained coder, and 22 BCTs were identified in 16 (40 %) or more of 40 descriptions. Good inter-coder reliability was observed across 80 BCTs identified in the protocols: 66 (80 %) achieved mean prevalence and bias-adjusted kappa (PABAK) scores of 0.70 or greater, and 59 (74 %) achieved mean scores of 0.80 or greater. There was good within-coder agreement between baseline and 1 month, demonstrating good test-retest reliability. BCTTv1 can be used by trained coders to identify BCTs in intervention descriptions reliably. However, some...
A Taxonomy of Behavior Change Methods; an Intervention Mapping Approach
Health psychology review, 2015
In this paper, we introduce the IM taxonomy of behavior change methods and its potential to be developed into a coding taxonomy. That is, although IM and its taxonomy of behavior change methods are not in fact new, because IM was originally developed as a tool for intervention development, this potential was not immediately apparent. Second, in explaining the IM taxonomy and defining the relevant constructs, we call attention to the existence of parameters for effectiveness of methods, and explicate the related distinction between theory-based methods and practical applications and the probability that poor translation of methods may lead to erroneous conclusions as to method-effectiveness. Third, we recommend a minimal set of intervention characteristics that may be reported when intervention descriptions and evaluations are published. Specifying these characteristics can greatly enhance the quality of our meta-analyses and other literature syntheses. In conclusion, the dynamics of...

Behavior change interventions typically contain multiple potentially active components: behavior change techniques (BCTs). Identifying which specific BCTs or BCT combinations have the potential to be effective for a given behavior in a given context presents a major challenge. The aim of this study was to review the methods that have been used to identify effective BCTs for given behaviors in given contexts and evaluate their strengths and limitations. A scoping review was conducted of studies that had sought to identify effective BCTs. Articles referring to "behavio(u)r change technique(s)" in the abstract/text were located, and ones that involved identification of effective BCTs were selected. The methods reported were coded. The methods were analyzed in general terms using "PASS" criteria: Practicability (facility to apply the method appropriately), Applicability (facility to generalize from findings to contexts and populations of interest), Sensitivity (facil...
