Disorders of arousal (DOA) are parasomnias occurring during Non-REM Sleep (NREM), stemming from incomplete arousal from slow wave sleep and resulting in diverse, complex emotional and motor behaviours. Growing evidence suggests that distinct psychopathological traits play a role in the multifaceted genesis of these occurrences. This multicentre study aims to characterize the personality profiles of adults with and without DOA using the Temperament and Character Inventory-Revised. We included 39 patients diagnosed with DOA (mean age=30.9±10.2 years, 22 females) and 40 healthy control subjects matched for age and gender (mean age of 32.4±11.6 years, 21 females). Participants completed the Paris Arousal Disorder Severity Scale, the Epworth Sleepiness Scale, the Sleep Condition Indicator, and the Temperament and Character Inventory-Revised. Higher levels of Harm Avoidance, Reward Dependence, and Persistence were predictive of the occurrence of DOA, as were elevated Anticipatory Worry and Attachment, and low Self-directedness. These findings support the hypothesis that certain psychobiological personality traits may be associated with the occurrence of DOA. To deepen our understanding, prospective studies are essential, aiming to delve into the causal relationship between the psychopathological profile and the clinical manifestation of DOA and assess the impact of targeted psychological interventions on DOA symptomatology.

To adapt and validate the original version of the Richards-Campbell Sleep Questionnaire (RCSQ) for the Spanish context, and to assess its psychometric properties for use in the pediatric population aged 7-17 years admitted to a Pediatric Intensive Care Unit (PICU). A descriptive observational study was conducted in a tertiary/high-complexity PICU in Madrid, Spain. This research was divided into two phases: phase I included translation of the original RCSQ into Spanish and assessment of content validity using the Content Validity Index (CVI). Subsequently, semantic and linguistic adaptation was conducted with the collaboration of psycho-pedagogy specialists and interviews with children. In phase II, the psychometric properties of the questionnaire were evaluated by calculating internal consistency using Cronbach's alpha. After successfully completing the translation process, a group of 11 experts evaluated content validity, obtaining a global CVI=0.836. Following semantic and linguistic adaptation, 10 interviews were conducted with children, resulting in the PRE-FINAL RCSQ-PED version. Next, the PRE-FINAL version was completed by 70 children admitted to the PICU, obtaining a strong internal consistency (Cronbach's α=0.84). The mean score was 64.19±24.41, indicating that 55.71% (n=39) of participants had acceptable sleep quality according to the 63-point cutoff. The results reported for the RCSQ-PED demonstrate excellent content validity and good internal consistency, with results like those obtained during the validation of the RCSQ in other contexts. This research is the first to validate a self-reported questionnaire for assessing sleep quality in Spanish pediatric critically ill patients.
