A growing body of evidence suggests that affective judgements are distinct from, and exert greater influence on, physical activity behaviours than instrumental judgements.
As part of a randomised controlled trial, 110 insufficiently active, female, university students were randomised to (a) an affective mental contrasting condition, (b) an instrumental mental contrasting condition, or (c) a 'standard' mental contrasting intervention (with no modifications). In the analyses concerning the trial's primary outcome, the affective mental contrasting condition was found to be more effective for increasing physical activity than the standard or instrumental conditions. The purpose of this study was to qualitatively examine the physical activity outcomes and obstacles elicited from participants as part of the three mental contrasting interventions within this trial.
32 lower-order physical activity judgement themes, categorised within seven high-order themes, were derived through the use of the mental contrasting intervention. In addition to identifying several affective and instrumental outcomes and obstacles that have previously been recognised, participants in this study also highlighted contextualised responses that describe complicated relationships that exist between affective and instrumental judgements.
This study provides fine-grained insight into cognitive processes derived from a novel intervention involving insufficiently active women.
越来越多的证据表明，情感判断与身体活动行为的关系比工具性判断更为独特，对其影响也更大。
作为一项随机对照试验的一部分，将 110 名身体活动不足的女性大学生随机分为（a）情感心理对比组、（b）工具性心理对比组或（c）“标准”心理对比干预组（无修改）。在分析该试验的主要结果时，发现情感心理对比组在增加身体活动方面比标准或工具性条件更有效。本研究旨在通过使用心理对比干预，从该试验的三个心理对比干预中定性地检查参与者的身体活动结果和障碍。
通过使用心理对比干预，得出了 32 个较低层次的身体活动判断主题，分为 7 个较高层次的主题。除了确定之前已经认识到的一些情感和工具性的结果和障碍外，本研究的参与者还强调了描述情感和工具性判断之间存在的复杂关系的情境化反应。
本研究深入了解了涉及身体活动不足的女性的一项新干预措施所产生的认知过程。
