PURPOSE/OBJECTIVE: Previous studies have demonstrated important associations between personal resources and pain interference. Using latent profile analysis, the present study (a) identified subgroups of individuals with chronic pain who have different personal resource profiles; (b) explored sociodemographic differences among subgroups; and (c) examined how these subgroups differ in pain interference. Research Method/Design: Study 1 is based on daily diary and survey data from 220 individuals with fibromyalgia (FM). Study 2 is based on 4 annual surveys of 483 individuals with long-term neurological/neuromuscular disease or injury, and chronic pain. Modifiable personal resource variables including sense of resilience, social support, pain acceptance, and sleep quality were included in latent profile analyses.
Three subgroups were identified in both studies: High, Moderate, and Low Personal Resource groups. In both studies, annual income level was significantly different among subgroups. Study 1 results showed a significant between-groups difference in pain interference across 21-days only between High and Moderate Personal Resource groups controlling for the level of pain intensity and depressive symptoms. In Study 2, however, all subgroups were significantly different with respect to their levels of pain interference at baseline over and above various covariates, with the Low Personal Resource group reporting the highest level of pain interference at baseline. These baseline differences remained stable over 4 years.
CONCLUSIONS/IMPLICATIONS: The findings suggest a robust association between economic disparity and personal resource profiles among individuals with chronic pain. The role of different personal resource profiles in pain interference appears to differ by chronic pain condition. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
目的/目标：先前的研究表明，个人资源与疼痛干扰之间存在重要关联。本研究采用潜在剖面分析方法：（a）确定具有不同个人资源特征的慢性疼痛个体亚组；（b）探讨亚组之间的社会人口学差异；（c）研究这些亚组在疼痛干扰方面的差异。
研究方法/设计：研究 1 基于 220 名纤维肌痛症（FM）患者的日常日记和调查数据。研究 2 基于对 483 名患有长期神经/神经肌肉疾病或损伤和慢性疼痛的个体的 4 项年度调查。可改变的个人资源变量包括韧性感、社会支持、疼痛接受度和睡眠质量，这些变量被纳入潜在剖面分析。
在两项研究中均识别出 3 个亚组：高个人资源组、中个人资源组和低个人资源组。在两项研究中，亚组之间的年收入水平均存在显著差异。研究 1 的结果表明，在控制疼痛强度和抑郁症状水平的情况下，仅在高个人资源组和中个人资源组之间，21 天内的疼痛干扰存在显著的组间差异。然而，在研究 2 中，所有亚组在基线时的疼痛干扰水平均存在显著差异，超过了各种协变量，低个人资源组报告的基线疼痛干扰水平最高。这些基线差异在 4 年内保持稳定。
结论/意义：研究结果表明，在慢性疼痛患者中，经济差距与个人资源特征之间存在很强的关联。不同个人资源特征在疼痛干扰中的作用似乎因慢性疼痛状况而异。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
