Physical disability and depression in patients with chronic pain have been shown to be associated with pain intensity and pain self-efficacy beliefs. However, little is known about whether pain self-efficacy beliefs can predict depression and physical disability when this relationship is controlled for pain intensity and other related demographic variables The aim of the current study was to replicate and extend previous research on the relationship between pain-related beliefs, depression, and disability by examining these relationships in a heterogeneous sample of Iranian patients with chronic pain.
A group of 430 patients with chronic pain participated in the study and completed questionnaires on demographic variables, pain intensity, pain self-efficacy beliefs, physical disability, and depression.
Correlation analyses revealed that patients with higher education were less depressed and less physically disabled. Younger patients were more physically disabled. Pain intensity and pain self-efficacy beliefs were significantly related to physical disability and depression. In hierarchical multiple regression analyses, after controlling for patients' background variables and pain intensity, pain self-efficacy beliefs accounted for significant variance in depression and physical disability over and above the effect of demographic variables and pain intensity. Patients with higher pain self-efficacy, compared to those with lower self-efficacy, were less depressed and less physically disabled.
Pain self-efficacy was more strongly related to depression and physical disability than pain intensity and demographic variables. The findings of the present study suggest the importance of targeting pain self-efficacy beliefs for modification in treatment of patients with chronic pain.
慢性疼痛患者的身体残疾和抑郁已被证明与疼痛强度和疼痛自我效能信念有关。然而，当这种关系在控制疼痛强度和其他相关人口统计学变量的情况下，疼痛自我效能信念是否能够预测抑郁和身体残疾，目前所知甚少。本研究的目的是通过在伊朗慢性疼痛患者的异质样本中检验这些关系，来复制和扩展先前关于疼痛相关信念、抑郁和残疾之间关系的研究。
一组430名慢性疼痛患者参与了该研究，并完成了关于人口统计学变量、疼痛强度、疼痛自我效能信念、身体残疾和抑郁的问卷。
相关分析显示，受教育程度较高的患者抑郁程度较低，身体残疾程度也较低。较年轻的患者身体残疾程度更高。疼痛强度和疼痛自我效能信念与身体残疾和抑郁显著相关。在分层多元回归分析中，在控制了患者的背景变量和疼痛强度后，疼痛自我效能信念在人口统计学变量和疼痛强度的影响之外，还能显著解释抑郁和身体残疾的变异。与自我效能较低的患者相比，疼痛自我效能较高的患者抑郁程度较低，身体残疾程度也较低。
疼痛自我效能与抑郁和身体残疾的关系比疼痛强度和人口统计学变量更为密切。本研究结果表明，在慢性疼痛患者的治疗中，针对疼痛自我效能信念进行调整具有重要意义。
