Psychological theories aiming to understand these behaviours typically focus on predictors of only one behaviour. Yet, behaviour enactment is often a choice between options. This study sought to examine predictors of PA and ST in a single model. Variables were drawn from dual process models, which portray behaviour as the outcome of deliberative and automatic processes. Design 411 Finnish vocational school students (age 17-19) completed a survey, comprising variables from the Reasoned Action Approach (RAA) and automaticity pertaining to PA and ST, and self-reported PA and ST four weeks later. Main outcome measures Self-reported time spent on PA and ST and their predictors. Results PA and ST correlated negatively (r = -.17, p = .03). Structural equation modelling revealed that intentions and habit for PA predicted PA while ST was predicted by intentions and habit for ST and negatively by PA intentions. RAA-cognitions predicted intentions. Conclusion PA and ST and their psychological predictors seem to be weakly interlinked. Future studies should assess more behaviours and related psychological influences to get a better picture of connections between different behaviours.20engcc_byinfo:eu-repo/semantics/openAccessPhysical activityscreen timereasoned action approachautomaticitystructural equation modellingHEALTH BEHAVIOR-CHANGESEDENTARY BEHAVIORREASONED ACTIONPLANNED BEHAVIORPAST BEHAVIORREPORT CARDCHILDRENINTERVENTIONSMETAANALYSISINACTIVITY5144 Social psychologyArticleopenAccessa4b4116f-75c9-4358-86e5-6119e0b17dc885117212275000708273700001
