This study investigated the question-behaviour effect of measuring intention in the interrogative or declarative form combined or not with a measure of moral norm.
A sample of 762 participants was randomised according to a 2 × 2 factorial design.
Cognitions were assessed at the baseline, and physical activity behaviour was self-reported three weeks later.
At baseline, there were no significant differences on the studied variables. An ANOVA showed a significant interaction effect between the two experimental conditions (p = 0.04). Post-hoc contrast analyses showed that the interrogative intention-only condition significantly differed from the declarative intention-only (d = 0.21, p = 0.03) and interrogative intention + moral norm (d = 0.22, p = 0.03) conditions.
Results suggest that self-posed questions about a future action increases the likelihood of doing it when these questions are not accompanied by measures of moral norm. This provides support for using introspective self-talk to favour the adoption of behaviour.
本研究探讨了在疑问句或陈述句中测量意图，并结合或不结合道德规范测量，对意图行为的影响。
根据 2×2 析因设计，对 762 名参与者进行随机分组。
在基线时评估认知，3 周后报告身体活动行为。
在基线时，研究变量没有显著差异。方差分析显示两种实验条件之间存在显著的交互作用效应（p=0.04）。事后对比分析显示，仅提问意图的疑问句条件与仅陈述意图（d=0.21，p=0.03）和提问意图+道德规范（d=0.22，p=0.03）条件存在显著差异。
结果表明，当问题不涉及道德规范时，对未来行为进行自我提问会增加采取该行为的可能性。这为使用内省性自我对话来促进行为的采纳提供了支持。
