PURPOSE/OBJECTIVE The objective of the study was to examine the BIS-BAS model of chronic pain. This model posits that 2 neurophysiological systems-the behavioral inhibition system (BIS) sensitized to and activated by punishment cues and the behavioral activation system (BAS) sensitized to and activated by reward cues-make independent and concurrent contributions to 2 domains of pain-related function: pain interference and positive function despite pain. The study additionally hypothesized that BIS and BAS sensitivity would have different associations with these 2 different aspects of pain-related function. BIS activation would be more strongly correlated with pain interference and BAS would be more strongly correlated with positive function despite pain. Research Method/Design: This was a cohort study consisting of the baseline assessments of 328 veterans enrolled in a large clinical trial examining 3 psychosocial interventions for chronic pain. RESULTS In multivariable regression adjusting for demographic factors and pain intensity, BIS was associated with greater pain interference and less positive function despite pain. BAS was associated with greater positive function despite pain but to a lesser degree than BIS. CONCLUSIONS As hypothesized, BIS and BAS both contributed to pain-related function; however, BIS displayed stronger associations with both pain interference and positive function despite pain. Thus, the hypothesis that BIS-BAS relationships would differ based on the nature of the functional outcome (BIS resulting in poorer function because of pain and BAS better function despite pain) was only partially supported. Findings of the current study suggest the role of BIS in chronic pain may be more pervasive across functional outcomes. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

行为激活和行为抑制：慢性疼痛功能检查。

目的/目标 本研究的目的是检查慢性疼痛的 BIS-BAS 模型。该模型假设 2 个神经生理系统——对惩罚线索敏感和激活的行为抑制系统 (BIS) 和对奖励线索敏感和激活的行为激活系统 (BAS)——对疼痛相关的 2 个领域做出独立和同时的贡献功能：疼痛干扰和尽管疼痛的积极功能。该研究还假设 BIS 和 BAS 敏感性与疼痛相关功能的这两个不同方面有不同的关联。BIS 激活与疼痛干扰的相关性更强，尽管疼痛，BAS 与积极功能的相关性更强。研究方法/设计：这是一项队列研究，包括对 328 名退伍军人的基线评估，这些退伍军人参加了一项大型临床试验，检查了 3 种针对慢性疼痛的社会心理干预措施。结果 在调整人口因素和疼痛强度的多变量回归中，BIS 与更大的疼痛干扰和更少的积极功能相关，尽管有疼痛。尽管疼痛，BAS 与更大的积极功能相关，但程度低于 BIS。结论 正如假设的那样，BIS 和 BAS 均有助于疼痛相关功能。然而，尽管有疼痛，BIS 仍显示出与疼痛干扰和积极功能更强的关联。因此，BIS-BAS 关系会因功能结果的性质而有所不同（BIS 因疼痛而导致功能更差，尽管疼痛导致 BAS 功能更佳）的假设仅得到部分支持。目前的研究结果表明，BIS 在慢性疼痛中的作用可能在功能结果中更为普遍。（PsycINFO 数据库记录 (c) 2020 APA，保留所有权利）。
