Abstract

Over the past few decades, research has suggested that cognitive variables play a key role in sleep disorders, particularly, in insomnia. The SLOC (Sleep Locus of Control Scale) evaluates the sleep locus of control, which is associated with the degree to which an individual attributes her/his experiences of sleep to chance or internal causes. The aim of this study was to develop the first translation and adaptation of the SLOC into the European Portuguese, as well as to analyze its psychometric properties. In this study, it was recruited a sample of 2029 Portuguese Higher Education students, aged ≥ 18 years, where approximately 75% of the sample were women and 25% men. The results showed that the SLOC had acceptable internal consistency value (α = .64), considering that it is a measure with a reduced number of items. As in the original study, a principal component analysis with varimax rotation identified two components. A parallel analysis was also conducted, identifying two factors. The correlation between the two subscales "internal sleep locus of control" and "chance sleep locus of control" was positive albeit of low magnitude (r = .15). Through the analysis carried out, it was also observed that individuals with "insomnia", relative to those without, had a more chance sleep locus of control. Overall, these findings show similarities with the original study. The SLOC seems to be a useful psychological assessment measure to be used in clinical and research settings.

葡萄牙人睡眠控制点(SLOC)量表的心理测量特征

在过去的几十年里，研究表明，认知变量在睡眠障碍，特别是失眠中起着关键作用。SLOC(睡眠控制点量表)评估睡眠控制点，它与个体将自己的睡眠经历归因于偶然或内在原因的程度有关。本研究的目的是开发第一个翻译和改编的SLOC到欧洲葡萄牙语，并分析其心理测量特性。在这项研究中，招募了2029名年龄≥18岁的葡萄牙高等教育学生作为样本，其中约75%的样本为女性，25%的样本为男性。结果表明，考虑到SLOC是一个减少了项目数量的测量，它具有可接受的内部一致性值(α = .64)。在最初的研究中，主成分分析与最大旋转确定了两个成分。还进行了平行分析，确定了两个因素。“内在睡眠控制点”和“偶然睡眠控制点”两个分量表的相关性虽低，但均为正相关(r = 0.15)。通过分析，我们还观察到，有“失眠症”的人，相对于没有“失眠症”的人，有更多的机会控制睡眠。总的来说，这些发现与最初的研究有相似之处。在临床和研究中，SLOC似乎是一种有用的心理评估方法。

期刊介绍： The Journal of Rational-Emotive and Cognitive Behavior Therapy is an international journal that publishes scholarly original papers concerning Rational Emotive Behavior Therapy (REBT), Cognitive Behavior Therapy (CBT), behavior therapy, cognitive-behavioral hypnosis, and hypnotherapy, clinical and counseling psychology, psychiatry, mental health counseling, and allied areas of science and practice. The journal encourages scholarly debate amongst professionals involved in practice, theory, research, and training in all areas of scholarship relevant to REBT and CBT. The Journal is particularly interested in articles that define clinical practice and research and theoretical articles that have direct clinical applications. The Journal seeks theoretical discussions and literature reviews on the cognitive bases of the development and alleviation of emotional, behavioral, interpersonal, personality, and addictive disorders. We consider submissions on the applications of REBT and CBT to new areas of practice and client populations. The Journal considers the term Cognitive Behavior Therapy to represent a generic, overriding category or school of psychotherapy approaches that includes many different theories and techniques. The journals encourages research that clearly identifies the specific hypothetical constructs and techniques being measured, tested, and discussed, and the comparison of the relative influence of different cognitive processes, constructs, and techniques on emotional and behavioral disturbance. The Journal provides a timely introduction to unexplored avenues on the cutting edge of REBT and CBT research, theory, and practice.The Journal publishes:discussions of the philosophical foundations of psychotherapiestheory-buildingtheoretical articlesoriginal outcome research articlesbrief research reportsoriginal research on the support of theoretical models development of scales to assess cognitive and affective constructsresearch reviewsclinical practice reviewsempirically-based case studiesdescriptions of innovative therapeutic techniques and proceduresadvances in clinical trainingliterature reviews book reviewsUnder the guidance of an expanded, international editorial board consisting of acknowledged leaders in the field, the journal disseminates current, valuable information to researchers and practitioners in psychology, psychotherapy, psychiatry, mental health counseling, social work, education, and related fields.Manuscripts usually are less than 35 pages, double-spaced, and using 11 or 12-point font. If the authors need more space to communicate their research or ideas, they should write to the editors to discuss this issue and provide a rationale why more than the commended number of pages is needed.
