Abstract

Objectives

The Cognitive Complaints Rating Scale in Bipolar Disorder (COBRA) is a brief self-report measure designed to capture Subjective Cognitive Complaints (SCC) experienced by patients with Bipolar Disorder (BD). This study aimed to translate the 16-item COBRA into Turkish (COBRA-TR) and comprehensively assess its psychometric properties.

Methods

We recruited 160 participants, consisting of 80 BD patients in remission and 80 controls. The psychometric evaluation included confirmatory factor analysis (CFA), calculation of internal consistency, and examination of divergent and convergent validity through Pearson's correlations with related scales. Statistical analyses were performed using the SPSSv29 and the Jamovi software of R Statistical Package.

Results

The COBRA-TR showed excellent internal consistency (Cronbach α = 0.898) and robust convergent validity, strongly correlating with the Cognitive Failures Questionnaire (r = 0.784; p < 0.001). It demonstrated moderate-to-high correlations with cognitive (r = 0.574; p < 0.001) and global functioning (r = 0.624; p < 0.001), as assessed by the Functioning Assessment Short Test. CFA provided strong support for a unidimensional factor structure. Furthermore, the COBRA-TR successfully differentiated patients from controls. Clinical variables minimally influenced the scale, though it showed weak correlations with subclinical depressive symptoms (r = 0.325; p = 0.003) and working memory performance (r = −0.250; p = 0.002).

Conclusion

Our findings highlight that the COBRA-TR is a highly reliable and valid tool, effectively capturing SCC among BD patients. Its brevity, ease of administration, and strong psychometric properties suggest its potential utility as a valuable instrument in both clinical practice and research settings.

双相情感障碍评定中土耳其语版认知主诉的效度和信度研究

目的双相情感障碍认知投诉评定量表（COBRA）是一种简短的自我报告量表，旨在记录双相情感障碍（BD）患者的主观认知投诉（SCC）。本研究旨在将16项COBRA翻译成土耳其语（COBRA- tr），并全面评估其心理测量特性。方法我们招募了160名参与者，包括80名缓解期BD患者和80名对照组。心理测量评估包括验证性因子分析（CFA），内部一致性计算，并通过Pearson与相关量表的相关检验发散效度和收敛效度。采用SPSSv29和R统计软件包中的Jamovi软件进行统计分析。结果COBRA-TR量表具有良好的内部一致性（Cronbach α = 0.898）和鲁棒的收敛效度，与认知失败问卷具有很强的相关性（r = 0.784; p < 0.001）。功能评估短测试显示，它与认知功能（r = 0.574; p < 0.001）和整体功能（r = 0.624; p < 0.001）具有中等到高度的相关性。CFA为一维因子结构提供了强有力的支持。此外，COBRA-TR成功地将患者与对照组区分开来。临床变量对量表的影响最小，但它与亚临床抑郁症状（r = 0.325; p = 0.003）和工作记忆表现（r = - 0.250; p = 0.002）呈弱相关性。结论我们的研究结果表明，COBRA-TR是一种高度可靠和有效的工具，可以有效地捕获BD患者的SCC。它的简洁，易于管理和强大的心理测量特性表明它在临床实践和研究环境中作为一种有价值的工具的潜在效用。

期刊介绍： The International Journal of Methods in Psychiatric Research (MPR) publishes high-standard original research of a technical, methodological, experimental and clinical nature, contributing to the theory, methodology, practice and evaluation of mental and behavioural disorders. The journal targets in particular detailed methodological and design papers from major national and international multicentre studies. There is a close working relationship with the US National Institute of Mental Health, the World Health Organisation (WHO) Diagnostic Instruments Committees, as well as several other European and international organisations. MPR aims to publish rapidly articles of highest methodological quality in such areas as epidemiology, biostatistics, generics, psychopharmacology, psychology and the neurosciences. Articles informing about innovative and critical methodological, statistical and clinical issues, including nosology, can be submitted as regular papers and brief reports. Reviews are only occasionally accepted. MPR seeks to monitor, discuss, influence and improve the standards of mental health and behavioral neuroscience research by providing a platform for rapid publication of outstanding contributions. As a quarterly journal MPR is a major source of information and ideas and is an important medium for students, clinicians and researchers in psychiatry, clinical psychology, epidemiology and the allied disciplines in the mental health field.
