The Cohen Perceived Stress Scale is being used widely in various countries. The present study evaluated the validity and reliability of the Cohen 10-item Perceived Stress Scale (PSS-10) in assessing tension headache, migraine, and stress-related diseases in Iran.
This study is a methodological and cross-sectional descriptive investigation of 100 patients with chronic headache admitted to the pain clinic of Baqiyatallah Educational and Therapeutic Center. Convenience sampling was used for subject selection. PSS psychometric properties were evaluated in two stages. First, the standard scale was translated. Then, the face validity, content, and construct of the translated version were determined.
The average age of participants was 38 years with a standard deviation (SD) of 13.2. As for stress levels, 12% were within the normal range, 36% had an intermediate level, and 52% had a high level of stress. The face validity and scale content were remarkable, and the KMO coefficient was 0.82. Bartlett's test yielded 0.327 which was statistically significant (p<0.0001) representing the quality of the sample. In factor analysis of the scale, the two elements of "coping" and "distress" were determined. A Cronbach's Alpha coefficient of 0.72 was obtained. This confirmed the remarkable internal consistency and stability of the scale through repeated measure tests (0.93).
The Persian PSS-10 has good internal consistency and reliability. The availability of a validated Persian PSS-10 would indicate a link between stress and chronic headache.
科恩感知压力量表在许多国家得到广泛应用。本研究评估了科恩 10 项感知压力量表（PSS-10）在评估伊朗紧张性头痛、偏头痛和与压力相关疾病中的有效性和可靠性。
这是一项对巴盖雅塔勒赫教育治疗中心疼痛诊所收治的 100 例慢性头痛患者进行的方法学和横断面描述性研究。采用方便抽样法选择受试者。分两个阶段评估 PSS 的心理测量特性。首先，对标准量表进行翻译。然后，确定翻译版本的表面有效性、内容和结构。
参与者的平均年龄为 38 岁，标准差为 13.2。至于压力水平，12%处于正常范围，36%处于中等水平，52%处于高水平。表面有效性和量表内容显著，KMO 系数为 0.82。巴特利特检验得出的 0.327 具有统计学意义（p<0.0001），代表样本质量。在量表的因子分析中，确定了“应对”和“痛苦”两个要素。Cronbach's Alpha 系数为 0.72，这通过重复测量测试（0.93）证实了该量表具有显著的内部一致性和稳定性。
波斯语 PSS-10 具有良好的内部一致性和可靠性。波斯语 PSS-10 的有效性证明了压力与慢性头痛之间存在联系。
