Research on the influence of chronotype and time of day (TOD) on cognitive performance, especially in children, is limited. We explored potential interactive effects, hypothesizing that performance differs when comparing preferred vs. non-preferred TOD. In total, 76 morning-type (MT = 37) or evening-type (ET = 39) children from the third and fourth grades (48.7% girls; M age = 8.05; SD age = 0.51), identified t...
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 adapta...
A avaliação psicológica é uma área fundamental que norteia todos os campos de intervenção e investigação em Psicologia. Ao longo das últimas décadas tem-se assistido a um crescente envolvimento dos psicólogos no âmbito do sono e das suas perturbações, sendo a Psicologia do Sono uma especialidade reconhecida pela American Psychological Association (APA) desde 2013. Paralelamente, constata-se o desenvolvimento de...
Objectives/Introduction: IQ tests are extensively used in school settings to evaluate children's specific cognitive deficits that may contribute to low academic achievement. Some studies found that IQ assessments’ results can vary according to testing time and chronotype. The present study aimed to probe potential chronotype X time of day (ToD) interactive effects on children's IQ results. Methods: Sixty-eight ...
Given the prevalence of sleep disorders, the efficacy and effectiveness of behavioural and cognitive interventions, mainly CBT for insomnia, we consider that a course on the topic should be introduced within the psychology master degree programmes. Since 2017/18 we are offering the optional course: Psychological Interventions on Sleep Disorders. The present work summarizes the course syllabus and analyses the s...
There is some evidence that insomnia seems to constitute a heterogeneous sleep disorder in which different psychological and neurophysiological variables may have differential roles. Mindfulness and acceptance-based approaches suggest new constructs for psychopathology and health sciences which can be useful to investigate in insomnia. In this paper, our aim was to explore eventual homogenous subgroups pertaini...
The association between sleep quality and quality of life (QoL) in clinical samples diagnosed with sleep disorders, mental disorders, or other medical conditions has been widely investigated. However, few studies focused on this relationship in samples of mostly young and healthy adults. This study analyzed the associations between sleep quality and several dimensions of QoL in higher education students and exa...
