  - The nocebo (or negative placebo) effect is an under-researched phenomenon with serious clinical implications. Research has shown an inverse relationship between nocebo responding and optimism, affected by situational variables. This study examined how biofeedback affects this relationship. Thirty-three undergraduates were randomly assigned to one of four conditions in a 2x2 design [Group variables: nocebo instructions (pill affecting heart rate/ inactive) and biofeedback (present/absent)]. Optimism was measured by the LOT-R and response by change in HRV. Mixed between-within ANOVAs revealed no significant effects on HRV for nocebo instructions or biofeedback. Controlling for pre-intervention HRV, there was a correlation between post-intervention HRV and LOT-R scores in one group (nocebo instructions present, biofeedback absent: r1/4.763, p1/4.028, two-tailed). Higher optimism increased nocebo responding in the simple nocebo condition, contrary to extant researc
