Ethnic differences in the perception, experience, and impact of pain have received growing attention in recent years. Although studies comparing pain among African Americans, Hispanics, and whites have yielded mixed findings, increasing evidence suggests an enhancement of the pain experience for African American and Hispanic patients. Mechanisms proposed to account for this effect include systematic differences in psychological distress and in pain-coping strategies, or differential relationships between these factors and pain. However, few studies have evaluated all of these variables, or matched ethnic groups precisely on potential confounds.
The present study compares African American, Hispanic, and white chronic pain patients across multiple dimensions of pain, emotional distress, pain-related disability, and pain coping after matching patients on a variety of potentially confounding variables.
Results indicated no significant ethnic differences on measures of pain, depression, psychopathology, or pain-related disability. While most coping variables did not differ by ethnicity, substantive group differences were evident on the praying and hoping subscale of the Coping Strategies Questionnaire, with African Americans and Hispanics reporting higher scores relative to whites on items relating to prayer. Inter-relationships among pain, coping, and distress were generally quite similar across ethnic groups, although active coping showed some variation in its relationship with pain-related outcomes. Catastrophizing was generally associated with greater pain and distress, and use of prayer/hope as a coping strategy was associated with greater disability across ethnic groups.
These results suggest that ethnic differences in pain, pain-related sequelae, and affective factors may be small when ethnic groups are closely matched on confounding variables. Moreover, interventions designed to facilitate adaptive coping are likely to be effective across ethnic groups.
近年来,疼痛的感知、体验及影响方面的种族差异受到了越来越多的关注。尽管比较非裔美国人、西班牙裔和白人疼痛情况的研究结果不一,但越来越多的证据表明,非裔美国人和西班牙裔患者的疼痛体验有所增强。用于解释这种效应的机制包括心理困扰和疼痛应对策略的系统差异,或这些因素与疼痛之间的不同关系。然而,很少有研究评估所有这些变量,或在潜在混杂因素上精确匹配种族群体。
本研究在对各种潜在混杂变量进行匹配后,比较了非裔美国人、西班牙裔和白人慢性疼痛患者在疼痛、情绪困扰、疼痛相关残疾和疼痛应对等多个维度上的情况。
结果表明,在疼痛、抑郁、精神病理学或疼痛相关残疾的测量指标上,没有显著的种族差异。虽然大多数应对变量在种族上没有差异,但在应对策略问卷的祈祷和希望子量表上存在明显的群体差异,非裔美国人和西班牙裔在与祈祷相关的项目上得分高于白人。尽管积极应对与疼痛相关结果的关系存在一些差异,但疼痛、应对和困扰之间的相互关系在不同种族群体中总体上非常相似。灾难化思维通常与更大的疼痛和困扰相关,而将祈祷/希望作为一种应对策略与不同种族群体中更大的残疾相关。
这些结果表明,当种族群体在混杂变量上紧密匹配时,疼痛、疼痛相关后遗症和情感因素方面的种族差异可能很小。此外,旨在促进适应性应对的干预措施可能在不同种族群体中都有效。
