People with low back pain (LBP) with higher levels of external locus of control have a poorer prognosis and require greater improvements from active interventions in order to consider these interventions worthwhile. Whether locus of control levels differ between participants with LBP in a patient-health provider relationship and those waiting for treatment is unclear.
The aim was to investigate if differences in locus of control exist between participants with non-specific chronic LBP being treated (treatment group) and those waiting treatment (control group).
100 participants (50 per group) with low back symptoms for at least three months for the current episode of LBP and aged between 18 and 60 years were recruited. Multidimensional health locus of control questionnaire (MHLC) was used to collect their beliefs. Multiple linear regression adjusted for disability was used to compare health locus of control between both groups. Differences were described as mean differences and 95% confidence intervals.
Treatment group scored higher for external locus of control and lower for internal locus of control than control group. Mean differences (95% confidence intervals) were 2.7 points on possible 30-points difference (0.5 to 4.8) for external locus of control and -2.8 points (-5.4 to -0.1) for internal subscale.
Health locus of control was found to be different between treatment and control groups. Participants being treated had higher external locus of control and lower internal locus of control than control group.
具有较高外控倾向水平的下腰痛（LBP）患者预后较差，为了使积极干预措施被认为是值得的，他们需要从这些干预措施中获得更大改善。在患者-医疗服务提供者关系中患有LBP的参与者与等待治疗的参与者之间，其控制源水平是否存在差异尚不清楚。
旨在调查正在接受治疗的非特异性慢性LBP参与者（治疗组）与等待治疗的参与者（对照组）之间在控制源方面是否存在差异。
招募了100名参与者（每组50名），他们当前的LBP发作至少持续了三个月，年龄在18至60岁之间，有下腰症状。使用多维健康控制源问卷（MHLC）收集他们的信念。采用经残疾调整的多元线性回归来比较两组之间的健康控制源。差异以平均差异和95%置信区间来描述。
治疗组在外控倾向上的得分高于对照组，在内控倾向上的得分低于对照组。外控倾向的平均差异（95%置信区间）在可能的30分差异中为2.7分（0.5至4.8），内控子量表的平均差异为-2.8分（-5.4至-0.1）。
发现治疗组和对照组之间的健康控制源存在差异。与对照组相比，正在接受治疗的参与者具有更高的外控倾向和更低的内控倾向。
