The delivery of physical activity (PA) promotion messages is an important component of any PA intervention. Gain-framed messages appear beneficial for prevention (rather than detection) behaviors such as PA, but the effects are small and inconsistent. It is possible that these effects are moderated by motivational traits, but this has not been systematically tested in the context of PA promotion messages. This study tested whether motivational traits interact with message features to influence basic subjective perceptions of a standardised set of very brief PA promotion statements.
Fifteen statements were developed across five conditions, manipulated according to frame and kernel state. Participants (n = 800) rated statement content using semantic differential scales reflecting perceived gains/losses, costs/benefits, and positive/negative outcomes. Traits and PA were measured by survey.
Structural equation models revealed that ratings of gain-framed statements were positively related to approach motivation, and ratings of loss-framed statements were negatively related to avoidance motivation.
Observations support the presence of a congruency effect of motivational traits and message frame on basic perceptions of message content. Future studies should test the impact of these biases on indices of persuasion (attitude and intention) as well as intervention reach and effectiveness.
传递身体活动（PA）促进信息是任何PA干预的重要组成部分。收益框架信息似乎对诸如PA等预防（而非检测）行为有益，但效果较小且不一致。这些效果可能受到动机特质的调节，但尚未在PA促进信息的背景下进行系统测试。本研究测试了动机特质是否与信息特征相互作用，以影响一组标准化的非常简短的PA促进陈述的基本主观认知。
在五个条件下制定了15条陈述，根据框架和核心状态进行操纵。参与者（n = 800）使用反映感知收益/损失、成本/收益以及积极/消极结果的语义差异量表对陈述内容进行评分。通过调查测量特质和PA。
结构方程模型显示，收益框架陈述的评分与进取动机呈正相关，损失框架陈述的评分与回避动机呈负相关。
观察结果支持动机特质和信息框架在对信息内容的基本认知上存在一致性效应。未来的研究应测试这些偏差对说服指标（态度和意图）以及干预覆盖面和有效性的影响。
