The Pain Response Preference Questionnaire (PRPQ) assesses preferences regarding pain-related social support. The initial factor analytical study of the PRPQ produced four empirically supported scales labelled Solicitude, Management, Encouragement and Suppression. A second study produced similar findings, but suggested that the Management and Encouragement scales be combined into a single scale labelled Activity Direction.
To use factor analytical methods to evaluate these competing configurations of the PRPQ (ie, three versus four scales) and to further refine the measure. The ability of the PRPQ scales to account for pain severity and disability ratings was also evaluated.
Chronic pain patients (n=201) completed the PRPQ along with the Pain Catastrophizing Scale (PCS) and self-reports of pain severity and disability.
Confirmatory factor analysis indicated that both models tested provided a poor fit to the data. A follow-up exploratory factor analysis was used to further refine the PRPQ scales and resulted in scales labelled Solicitude, Encouragement and Suppression. Supportive of the potential clinical utility of the PRPQ, Suppression was positively associated with pain severity and Solicitude was positively associated with disability. These two scales were also positively associated with the PCS. Supportive of the incremental validity of the PRPQ, a multiple regression analysis indicated that the Solicitude scale accounted for unique variance in disability ratings beyond that accounted for by demographic⁄clinical variables and the PCS.
The PRPQ has promise as a clinical assessment measure and for advancing research examining the interpersonal context of pain.
疼痛反应偏好问卷(PRPQ)评估与疼痛相关的社会支持偏好。对PRPQ的初步因素分析研究产生了四个经实证支持的量表,分别标记为关怀、管理、鼓励和抑制。第二项研究得出了类似的结果,但建议将管理和鼓励量表合并为一个标记为活动指导的单一量表。
使用因素分析方法评估PRPQ的这些竞争性结构(即三个量表与四个量表),并进一步完善该测量方法。还评估了PRPQ量表解释疼痛严重程度和残疾评分的能力。
慢性疼痛患者(n = 201)完成了PRPQ以及疼痛灾难化量表(PCS)和疼痛严重程度及残疾的自我报告。
验证性因素分析表明,所测试的两个模型均与数据拟合不佳。后续的探索性因素分析用于进一步完善PRPQ量表,结果产生了标记为关怀、鼓励和抑制的量表。支持PRPQ的潜在临床效用,抑制与疼痛严重程度呈正相关,关怀与残疾呈正相关。这两个量表也与PCS呈正相关。支持PRPQ的增量效度,多元回归分析表明,关怀量表解释了残疾评分中超出人口统计学/临床变量和PCS所解释的独特方差。
PRPQ有望作为一种临床评估措施,并用于推进对疼痛人际背景的研究。
