It is often believed that to feel greater pain is to experience greater effects of that pain, and that attention and awareness represent the transmission mechanism in this relationship. By implication, it is assumed that if attention and awareness can be lessened, the effects of pain will likewise reduce. Despite conceptual work and data suggesting more complex processes might indeed be in place, these long-standing and intuitively appealing ideas remain, either explicitly or implicitly, in both research and clinical applications. The purpose of this study was to compare the role of attentional processes in chronic pain with a process that is more contextual, functional, and behavior-focused, namely, acceptance. The hypothesis tested is whether it is more important to understand the amount of contact an individual has with pain, in this case awareness and vigilance to pain, or the degree of influence on behavior brought with that contact, in this case acceptance. Data from 227 patients seeking treatment for chronic pain were examined. Results from correlation analyses showed that acceptance scores achieved stronger correlations than scores for the attention variables with measures of cognitive, emotional, social, and physical functioning. When acceptance of pain was taken into account in multiple regression analyses, scores from the attention measures accounted for little or no variance in measures of patient functioning. The value of various mental, mechanical, behavior-focused, and contextual models of attention in chronic pain is discussed.
Attention, awareness, and vigilance appear immediately applicable for understanding chronic pain. These processes, however, might be incomplete in accounting for pain-related suffering and disability. Acceptance is proposed as a process that expands the framework of attention to include varying cognitive, emotional, and social influences exerted by pain on patient behavior.
人们通常认为,感受更强烈的疼痛意味着经历该疼痛更显著的影响,且注意力和意识是这种关系中的传导机制。这意味着,人们假定如果注意力和意识能够减弱,疼痛的影响也会相应减轻。尽管概念性研究和数据表明可能确实存在更复杂的过程,但这些长期存在且直观上有吸引力的观点在研究和临床应用中仍然或明或暗地存在着。本研究的目的是将注意力过程在慢性疼痛中的作用与一个更具情境性、功能性且以行为为重点的过程(即接纳)进行比较。所检验的假设是,了解个体与疼痛的接触量(在这种情况下是对疼痛的意识和警觉),还是这种接触对行为带来的影响程度(在这种情况下是接纳)更为重要。对227名寻求慢性疼痛治疗的患者的数据进行了检查。相关分析结果表明,接纳得分与认知、情感、社会和身体功能指标的相关性比注意力变量得分更强。在多元回归分析中考虑对疼痛的接纳时,注意力测量得分在患者功能测量中几乎没有或没有解释方差。讨论了慢性疼痛中各种关注心理、机械、行为和情境模型的价值。
注意力、意识和警觉似乎可直接用于理解慢性疼痛。然而,这些过程在解释与疼痛相关的痛苦和残疾方面可能并不完整。接纳被提议作为一个过程,它扩展了注意力框架,以纳入疼痛对患者行为施加的各种认知、情感和社会影响。
