Data from: Behaviour changes techniques that constitute effective planning interventions to improve physical activity and diet behaviour for people with chronic conditions: a systematic review

Objectives: Action planning is a brief and effective behaviour change
technique (BCT) to improve physical activity (PA) and diet behaviour (DB).
This study aimed to identify critical BCTs and mechanisms of action (MoA)
to interpret the effectiveness of planning interventions based on the
health action process approach (HAPA) model. Design: Systematic review
Data Sources: PubMed, Web of Science, CIHNAL (EBSCO), PsycInfo (EBSCO),
Psychology and Behavioural Sciences Collection (EBSCO), psyARTICLES, and
Medline were searched for studies from January 1990 to September 2021
published in English. Eligibility Criteria: Experiment involving action
planning intervention to improve PA or DB in community-dwelling adult
patients with chronic conditions. Data extraction and synthesis: Two
reviewers independently coded the planning interventions into BCT
combinations and MoA assemblies. Outcome was dichotomized according to the
statistical power and Cohen's d. The Cochrane risk of bias assessment
tool and the Risk of Bias in Nonrandomized Studies of Intervention
assessment tool were used to assess the quality of RCTs and non-RCTs,
respectively. Results: From the 52 included studies, 46 BCTs were
identified and linked to 21 MoAs. Long-term facilitators for planning
intervention included 'self-monitoring of behaviour',
'problem solving', 'instruction on how to perform the
behaviour', and 'goal setting (behaviour)'. The most
frequently occurring MoA was "beliefs about capabilities". The
effective intervention groups had higher MoA scores that corresponded to
the HAPA model constructs than the ineffective groups. Conclusions: The
findings from this review may inform scientific and effective planning
intervention designs for community-dwelling people with chronic conditions
in the future.
