Perceived self-efficacy is a non-negligible outcome when measuring the impact of self-management interventions for chronic pain patients. However, no validated, chronic pain-specific self-efficacy scales exist for studies conducted with French-speaking populations.
To establish the validity of the use of the French-Canadian Chronic Pain Self-efficacy Scale (FC-CPSES) among chronic pain patients.
The Chronic Disease Self-Efficacy Scale is a validated 33-item self-administered questionnaire that measures perceived self-efficacy to perform self-management behaviours, manage chronic disease in general and achieve outcomes (a six-item version is also available). This scale was adapted to the context of chronic pain patients following cross-cultural adaptation guidelines. The FC-CPSES was administered to 109 fibromyalgia and 34 chronic low back pain patients (n=143) who participated in an evidence-based self-management intervention (the PASSAGE program) offered in 10 health care centres across the province of Quebec. Cronbach's alpha coefficients (α) were calculated to determine the internal consistency of the 33- and six-item versions of the FC-CPSES. With regard to convergent construct validity, the association between the FC-CPSES baseline scores and related clinical outcomes was examined. With regard to the scale's sensitivity to change, pre- and postintervention FC-CPSES scores were compared.
Internal consistency was high for both versions of the FC-CPSES (α=0.86 to α=0.96). Higher self-efficacy was significantly associated with higher mental health-related quality of life and lower pain intensity and catastrophizing (P<0.05), supporting convergent validity of the scale. There was a statistically significant increase in FC-CPSES scores between pre- and postintervention measures for both versions of the FC-CPSES (P<0.003), which supports their sensitivity to clinical change during an intervention.
These data suggest that both versions of the FC-CPSES are reliable and valid for the measurement of pain management self-efficacy among chronic pain patients.
在衡量自我管理干预措施对慢性疼痛患者的影响时，感知自我效能是一个不可忽视的结果。然而，对于说法语的人群进行的研究，尚无经过验证的、针对慢性疼痛的特定自我效能量表。
确定加拿大法语区慢性疼痛自我效能量表（FC-CPSES）在慢性疼痛患者中使用的有效性。
慢性病自我效能量表是一个经过验证的33项自填式问卷，用于测量执行自我管理行为、总体管理慢性病以及实现结果的感知自我效能（也有一个六项版本）。该量表根据跨文化适应指南进行了调整以适应慢性疼痛患者的情况。FC-CPSES被施用于109名纤维肌痛患者和34名慢性下腰痛患者（n = 143），这些患者参与了在魁北克省10个医疗保健中心提供的基于证据的自我管理干预（PASSAGE项目）。计算了克朗巴哈系数（α）以确定FC-CPSES的33项和六项版本的内部一致性。关于收敛性结构效度，研究了FC-CPSES基线分数与相关临床结果之间的关联。关于量表对变化的敏感性，比较了干预前后的FC-CPSES分数。
FC-CPSES的两个版本内部一致性都很高（α = 0.86至α = 0.96）。较高的自我效能与较高的心理健康相关生活质量以及较低的疼痛强度和灾难化显著相关（P < 0.05），支持了该量表的收敛效度。FC-CPSES两个版本的干预前后测量分数在统计学上有显著增加（P < 0.003），这支持了它们在干预期间对临床变化的敏感性。
这些数据表明，FC-CPSES的两个版本在测量慢性疼痛患者的疼痛管理自我效能方面都是可靠且有效的。
