Blood volume pulse biofeedback represents an effective non-pharmacological treatment for migraine. However, the underlying mechanisms of blood volume pulse biofeedback are still unclear. This study investigated the influence of vividness of imagination, private body consciousness, perfectionism, and general self-efficacy on physiological (blood volume pulse amplitude) and psychological (session performance rated by participants and by trainers) success. Changes in skin conductance and skin temperature indicating habituation to training context were examined. Forty-five healthy male participants were randomized to four sessions of vasoconstriction training or vasodilatation training. Hierarchical linear models were estimated. Results showed significant changes of session performance rated by participants (UC = 0.62, p < .05), by trainers (UC = 0.52, p < .001), and skin temperature (UC = 0.01, p < .001) over time. A change of blood volume pulse amplitude could not be observed (UC = -0.01, p = .65). Vividness of imagination was highly important for both psychological achievement ratings (UC = 1.3, p < .001; UC = 0.29, p < .01). Relations between skin temperature and general self-efficacy or personal standards were small (UC = 0.002, p < .10; UC = 0.002, p < .05). A time × group interaction regarding trainers' achievement ratings indicated a specific judgement effect. In conclusion, biofeedback trainers should pay attention to their beliefs and participants' vividness of imagination.
血量脉冲生物反馈代表一种有效的非药物治疗偏头痛的方法。然而，血量脉冲生物反馈的潜在机制仍不清楚。本研究调查了生动的想象力、私人身体意识、完美主义和一般自我效能感对生理（血量脉冲幅度）和心理（参与者和培训师评定的会话表现）成功的影响。还检查了指示对训练环境适应的皮肤电传导和皮肤温度的变化。45 名健康男性参与者被随机分配到四个血管收缩训练或血管舒张训练的会话中。使用分层线性模型进行估计。结果表明，参与者评定的会话表现（UC = 0.62，p <.05）、培训师评定的会话表现（UC = 0.52，p <.001）和皮肤温度（UC = 0.01，p <.001）随时间显著变化。未能观察到血量脉冲幅度的变化（UC = -0.01，p =.65）。生动的想象力对心理成就评定非常重要（UC = 1.3，p <.001；UC = 0.29，p <.01）。皮肤温度与一般自我效能感或个人标准之间的关系较小（UC = 0.002，p <.10；UC = 0.002，p <.05）。关于培训师成就评定的时间×组交互作用表明存在特定的判断效应。总之，生物反馈培训师应注意他们的信念和参与者的生动想象力。
