Abstract

Objective: Sensory processing sensitivity (SPS) describes a common trait characterized by lower sensory threshold, depth of processing, and ease of overstimulation. Low sensory threshold is also potentially important in the context of pain. To date, the relationship between SPS and pain perception has not been investigated, particularly in adolescents. This randomized experimental study aimed to explore whether SPS was associated with pain threshold and tolerance in healthy adolescents. Further, we examined differences in pain perception following positive, negative, or neutral mood induction.

Methods: A total of 100 healthy adolescents aged 16 to 19 years were recruited through schools and online advertisement. Participants completed psychosocial questionnaires and underwent a randomized mood induction (positive, negative, or neutral). Pain levels (in °C) and self-reported pain tolerance and threshold were assessed by an experimental heat pain paradigm. Regression models were applied to determine effects of mood induction on pain perception, while multiple analyses of variance (ANOVAs) were computed to compare sensitivity across groups.

Results: The mood induction significantly influenced self-reported pain ratings, demonstrating a positive interaction coefficient for the positive mood condition ( = 1.140, < 0.01). ANOVAs revealed significant differences between sensitivity groups for baseline scores of pain threshold (F = 5.009, p < 0.01) and tolerance (F = 3.193, < 0.05) (F = 7.431, p < 0.001).

Conclusion: Our findings reveal that highly sensitive adolescents had the lowest ratings of measured pain tolerance and threshold measures at baseline, suggesting heightened sensitivity to pain. This highlights the importance of considering sensory processing sensitivity in pain research, particularly in adolescent populations.
