摘要
ObjectivesRetrospective symptom reports tend to overestimate actual symptom intensity. This study explored how focusing on sensory-perceptual or on affective-motivational aspects of a somatic experience influenced retrospective symptom reports in high and low habitual symptom reporters (HSR). We hypothesized that a focus on affective-motivational aspects of somatic episodes contributes to retrospective overestimation compared to a focus on sensory-perceptual aspects. DesignDyspnoea (rebreathing) and pain (cold pain) were induced during two experimental sessions in healthy women: 21 high and 24 low HSR, selected using cut-off scores on a symptom checklist. Within-subject manipulation of sensory and affective processing focus (PF) took place at the encoding phase before symptom induction. MethodsDyspnoea and pain ratings were collected immediately after the symptom inductions and after 2weeks. Breathing behaviour was recorded during dyspnoea trials, while affective state and symptom measures were collected after each trial. ResultsCompared to pain, dyspnoea induction was perceived as more unpleasant, arousing, and threatening (ps<.001). Affective PF led to higher arousal (p<.01) and threat ratings (p=.01) than sensory PF. Affective PF also led to an increase in retrospective dyspnoea ratings over the course of 2weeks (p=.039), which was not observed for pain, nor for dyspnoea after sensory PF. The effects of PF on symptom ratings were independent of the HSR levels. ConclusionsThe PF during symptom encoding may explain previously observed bias in retrospective symptom reporting. The results are relevant to understand the mechanisms underlying symptom overreporting.
