Friends’ role in adolescents’ physical activity maintenance: Qualitative analysis of trial participants’ follow-up interviews

Katri Kostamo

  • Especially those participants, who reported only short-time PA increases, seemed to require their friends for support or company

WHEN AND WHERE?
15.30-17.00
Social factors in behavior change interventions (Poster session)
Room: Business Centre, Valamar Lacroma Hotel

Promoting physical activity and motivation with the Precious app: Usage findings from factorial n-of-1 RCTs 

Johanna Nurmi

  • To study the impact of specific intervention elements on an individual, N-of-1 randomised controlled trials (RCTs) randomise the timepoints when the participant receives interventions and compare those to control days when interventions are not offered. We discuss lessons learned from conducting a factorial n-of-1 RCT with the Precious app, and suggest ways to improve adherence in randomly timed within-person interventions.

Johanna is also the chair for the poster session.

Electrophysiological correlates of response inhibition training on high and low calorie food cues 

Matthias Aulbach

  • We investigated how a neural marker of response inhibition (the N2 event-related potential) discriminates between high- and low-calorie foods in a Go/No-Go-task and how it changes through food-Go/No-Go training. In this well-powered lab study, we did not find significant changes in N2-amplitudes through training.

Uptake of planning as a self-regulation strategy: Adolescents’ reasons for (not) planning physical activity 

Elina Renko

  • Although action and coping planning are potentially effective strategies for behaviour change, not all intervention participants take up planning. This study investigates how physical activity trial participants reason about their using or not using planning. Thematic analysis rendered seven categories of these reasons. We discuss possible ways to improve uptake of planning among intervention participants.

Self-regulation and health-related behaviors (Poster session)

Potential for change (PΔ): New metrics for tailoring and predicting response to behavior change interventions

Keegan Knittle

  • Behavior change interventions assume that changes in social, cognitive and environmental determinants of behavior lead to changes in behavior. To benefit from an intervention, an individual must be deficient in the target behavior and in one or more of its theoretical determinants. The presence of ceiling/floor effects therefore limits the theoretically-possible impact of an intervention on behavior. This talk introduces a novel integrative construct, potential for change (PΔ), which accounts for such ceiling/floor effects to predict an individual’s likelihood of response to an intervention. 

WHEN AND WHERE?
15.30-15.45 Understanding intervention effectiveness: Analysing potential for change, improving intervention reporting, and using machine-readable decision justifications (Rapid Communication Symposium)
Room: Elafiti 4, Valamar Lacroma Dubrovnik

Thematic analysis in assessing acceptability and fidelity of engagement for behaviour change interventions: The Let’s Move It intervention interview study

Minttu Palsola

  • This study provides an example of how to use thematic analysis to assess acceptability, receipt and enactment in interventions. Identifying misunderstandings and difficulties in skill acquisition can help interpret main trial outcomes and inform intervention optimisation. 

WHEN AND WHERE?
15.00-15.15 Diabetes and physical activity (Oral)
Room: Elafiti 4, Valamar Lacroma Dubrovnik
