The goal of the current study was to investigate the differential effects of three interoception dimensions on psychophysiological stress responses (reactivity and recovery) in adolescents. A total of 102 adolescents (M = 14.10 years, SD = 0.63; 50 males) completed the heartbeat counting task with adapted instructions to assess interoceptive accuracy, sensibility, and awareness. During a follow-up session, participants underwent a standardized stressful task, throughout which measures of negative affect and respiratory sinus arrythmia (RSA) were collected. Results from multilevel models indicated that adolescents with higher interoceptive accuracy reported less pronounced increases in negative affect during stress induction, and subsequently experienced a less steep decrease in negative affect during recovery, compared to those with lower accuracy. Regarding RSA, adolescents with higher interoceptive accuracy exhibited greater decreases in RSA from baseline to stress, while those with higher interoceptive awareness maintained higher RSA levels throughout the experiment. In contrast, individuals with higher interoceptive sensibility exhibited lower levels of RSA during the experiment. These findings add to the limited literature on interoception in adolescents by illuminating its role in emotional experiences, stress responses, and recovery processes. Our study suggests that examining distinct dimensions of interoception, along with physiological measures during stress and recovery, is crucial for understanding its beneficial or adverse effects in adolescence. The complexity and potential significance of interoceptive dimensions extend beyond their correlations with traditional self-report measures, warranting further investigation to clarify their implications and underlying mechanisms.
本研究旨在探讨三个内感受维度对青少年心理生理应激反应（反应和恢复）的差异影响。共有 102 名青少年（M=14.10 岁，SD=0.63；50 名男性）完成了经过改编的心跳计数任务，以评估内感受准确性、敏感性和意识。在后续的会议中，参与者经历了一项标准化的压力任务，在此过程中收集了负面情绪和呼吸窦性心律失常（RSA）的测量结果。多层次模型的结果表明，内感受准确性较高的青少年在应激诱导期间报告的负面情绪增加幅度较小，随后在恢复期间负面情绪的下降幅度也较小，而准确性较低的青少年则相反。关于 RSA，内感受准确性较高的青少年在从基线到压力期间表现出更大的 RSA 下降，而内感受意识较高的青少年在整个实验过程中保持较高的 RSA 水平。相比之下，内感受敏感性较高的个体在实验过程中表现出较低的 RSA 水平。这些发现通过阐明内感受在情绪体验、应激反应和恢复过程中的作用，为青少年内感受的有限文献做出了贡献。我们的研究表明，在应激和恢复期间检查内感受的不同维度以及生理指标，对于理解其在青少年时期的有益或不利影响至关重要。内感受维度的复杂性和潜在意义超出了它们与传统自我报告测量的相关性，需要进一步研究来阐明它们的含义和潜在机制。
