海洛因戒治者对疼痛线索的选择性注意加工偏向

Selective Attention Processing Bias towards Pain-Related Cues in Abstinent Heroin Addicts

研究采用点探测范式,以疼痛线索(感觉疼痛词、情感疼痛词和健康灾难词)和中性线索(中性词)为实验材料,考察接受美沙酮维持治疗的海洛因戒治者对疼痛线索的视觉选择性注意偏向。结果表明:海洛因戒治者对疼痛线索的注意偏向具有普遍性,即对感觉疼痛词、情感疼痛词和健康灾难词等三类疼痛线索均存在注意回避偏向,尤其对健康灾难词的注意回避程度最高;海洛因戒治者还对感觉疼痛词和情感疼痛词存在注意脱离易化倾向。本研究对于有针对性的开展注意偏向矫正以干预疼痛,从而辅助美沙酮的治疗效果、维持患者的戒断状态、降低其复吸风险具有重要意义。

This research examined selective attention processing bias toward pain-related words within a dot-probe paradigm in an abstinent heroin addict sample treated with methadone. Abstinent heroin addicts suffered frequent pain problems as patients with chronic pain. Based on the findings that chronic pain patients had attention avoidance to specific pain words, we hypothesized that abstinent heroin addicts had more general attention biases to pain cues. In the current study, 17 abstinent heroin addicts treated with methadone and 19 healthy control participants were recruited from a methadone section for outpatients. Firstly, they completed demographical information, the fear of pain questionnaire （the Chinese version）, and the depression, anxiety and stress scale.
