  Abstract:

  Examined the temporal relationship between sleep disturbances and paranoid ideation using concurrent objective actigraphy and ambulatory daily diary assessments over a 7-day period. Findings demonstrated that subjective sleep quality and objective sleep fragmentation significantly predicted next-day increases in paranoia, highlighting sleep stabilization as a critical therapeutic target in early interventions.

  Abstract:

  Experimentally investigated whether acute sleep deprivation amplifies paranoid thinking and persecutory beliefs in response to stressful cognitive tasks. Results indicated a causal link whereby sleep deprivation significantly elevated paranoia vulnerability, underscoring the protective function of restorative sleep architecture.

  Abstract:

  Employed ecological momentary assessment (EMA) to investigate the interplay of nocturnal sleep parameters, daytime positive affect, and state mindfulness on sustained attention performance in adolescents. Revealed that optimal sleep duration directly sustained attention stability throughout academic environments.
