Abstract

Background: Cognitive impairments are common in bipolar disorder, which can negatively impact patients' psychological and psychosocial functioning, but there are no tools for assessing cognitive deficits, especially in patients with bipolar disorder in Iran. Objectives: This study assessed the psychometric properties of the Cognitive Complaint in Bipolar Disorder Rating Assessment (COBRA) scale in Iranian patients with bipolar disorder (BD). Methods: Eighty patients diagnosed with bipolar spectrum disorder were selected from Tehran's major psychiatric facilities: Razi Psychiatric Hospital and Taleghani Hospital. A purposive sampling method was followed to select 80 non-patient control individuals from the general population in Tehran. Participants were evaluated using the Beck Depression Inventory-II (BDI-II), the Bech-Rafaelsen Mania Scale (BRAMS), the Mini-Mental State Examination (MMSE), and the Cognitive Complaint in Bipolar Disorder Rating Assessment (COBRA). The data were analyzed using SPSS-24 to evaluate convergent and discriminant validity, test-retest reliability, and internal consistency. Results: The convergent validity was examined by calculating the correlation between the scores on the COBRA and those on the MMSE; the results were significant (r = - 63, P < 0.001). Discriminant validity was assessed by comparing the COBRA total scores between the patients with BD and the control group; the results indicated a significant difference between the two groups (t = 6.413, P = 0.001). The CFA and EFA showed that the one-factor structure of COBRA was the best model. The Cronbach's alpha of 0.72 indicated an internal consistency. A test-retest reliability estimate of 0.84 indicated the high reliability of the scale. The current investigation suggested a cutoff score of 28, with 0.72 sensitivity and 0.69 specificity. Conclusions: Our translated version of the COBRA in Persian in this study showed adequate psychometric properties. This test can be considered an applicable instrument in investigating cognitive complaints in patients with bipolar disorder in Iran.

伊朗双相患者双相情感障碍评分评估(COBRA)中认知主诉的心理测量特征

背景：认知障碍在双相情感障碍中很常见，它会对患者的心理和社会心理功能产生负面影响，但没有评估认知缺陷的工具，尤其是在伊朗的双相情感疾病患者中。目的：本研究评估了伊朗双相情感障碍（BD）患者双相情感疾病认知抱怨评定量表（COBRA）的心理测量特性。方法：80名被诊断为双相情感障碍的患者来自德黑兰的主要精神病院：拉齐精神病院和Taleghani医院。采用有目的的抽样方法，从德黑兰的普通人群中选择80名非患者对照个体。参与者使用Beck抑郁量表II（BDI-II）、Bech-Rafaelsen躁狂量表（BRAMS）、迷你精神状态检查（MMSE）和双相情感障碍认知抱怨评分评估（COBRA）进行评估。使用SPSS-24对数据进行分析，以评估收敛和判别有效性、重测信度和内部一致性。结果：通过计算COBRA评分与MMSE评分之间的相关性来检验收敛有效性；结果有显著性（r=-63，P<0.001）。通过比较BD患者和对照组的COBRA总分来评估判别有效性；CFA和EFA显示，COBRA的单因素结构是最佳模型。克朗巴赫α为0.72，表明存在内部一致性。重新测试的信度估计值为0.84，表明该量表具有较高的信度。目前的调查表明，截止得分为28，敏感性为0.72，特异性为0.69。结论：在这项研究中，我们翻译的波斯语COBRA显示出足够的心理测量特性。该测试可被认为是调查伊朗双相情感障碍患者认知主诉的一种适用工具。
