The study evaluated the ability of the Pain Stages of Change Questionnaire (PSOCQ) to classify subjects into specific profiles of readiness to adopt a self-management approach to pain. An analysis was made of whether the five earlier described PSOCQ-profiles Precontemplation, Contemplation, Non-contemplative Action, Participation and Ambivalent could be reproduced by two different methods, cluster analysis and visual analysis. The 184 included subjects completed the PSOCQ, the Hopkins Symptom Checklist (HSCL-25), the Tampa scale of Kinesiophobia (TSK) and five self-efficacy questions from the arthritis self-efficacy questionnaire (ASES). Profiles were drawn based on the mean scores of the four subscales in PSOCQ. All the five predefined profiles were identified visually by two coders with an interrater agreement of Kappa 0.731. A 6-cluster solution generated the four profiles Precontemplation, Contemplation, Non-contemplative Action and Participation. Discriminant function analysis (DFA) on cluster analysis classified 83.5% of cases in the same group, and DFA on visual classification 72.1% of cases. Fifty-three percent were classified in the same profile by cluster and visual analysis. The two profiles Precontemplation and Participation seem to identify distinct subgroups that differ in educational level, pain during activity and psychometric measures. Non-contemplative Action share characteristics with Precontemplation, and the Contemplation group has scores in between. In conclusion, more research on the validity of the PSOCQ is needed. Outcome studies after pain treatment programmes could focus three main states that differ on measures for concurrent validity: Profiles that can be identified as Precontemplation or Non-contemplative action, Contemplators, and subjects with Participation profiles.
该研究评估了疼痛阶段变化问卷（PSOCQ）将受试者分为特定的准备状态以采用自我管理疼痛方法的能力。分析了是否可以通过两种不同的方法（聚类分析和视觉分析）再现之前描述的五个 PSOCQ 简档：未考虑、考虑、非考虑行动、参与和矛盾。184 名纳入的受试者完成了 PSOCQ、霍普金斯症状清单（HSCL-25）、坦帕运动恐惧症量表（TSK）和关节炎自我效能问卷（ASES）的五个自我效能问题。根据 PSOCQ 四个分量表的平均得分绘制了简档。两位编码员通过视觉分析识别了所有五个预定义的简档，两次评分的 Kappa 值为 0.731。6 聚类解决方案生成了四个简档：未考虑、考虑、非考虑行动和参与。聚类分析的判别函数分析（DFA）将 83.5%的病例分类为同一组，视觉分类的 DFA 将 72.1%的病例分类为同一组。53%的病例通过聚类和视觉分析被分类为同一简档。未考虑和参与这两个简档似乎确定了在教育程度、活动时疼痛和心理测量指标方面存在差异的不同亚组。非考虑行动与未考虑具有相似的特征，而考虑组的得分则介于两者之间。总之，需要进一步研究 PSOCQ 的有效性。疼痛治疗方案后的结果研究可以集中在三个主要状态上，这些状态在同时效度量表上存在差异：可以确定为未考虑或非考虑行动、考虑和参与简档的简档。
