• Research summary

  Background: Sleep is a common and significant problem amongst individuals diagnosed with a psychotic disorder
  and accounts for a major proportion of impairment in quality of life. Whilst it is well known that sleep quality is poor,
  exactly how poor the sleep is, and what specific aspects of sleep are disturbed is not known.
  Aims: Our overall aim is to quantify the level of sleep disturbance using subjective and objective measures of sleep
  and examine the impact of sleep upon symptom levels. More specifically we aim to: a) quantify the level of sleep
  disturbance in patients with a diagnosis of psychosis using subjective and objective measures b) compare and
  assess the correspondence between subjective and objective measures of sleep, c) assess the relationship between
  symptom levels and sleep and d) examine the day to day (temporal) relationship between sleep and symptoms.
  Method:
  Subjects and design: The study will be crosssectional,
  lasting 15 days. Participants with a diagnosis for a
  Schizophrenia Spectrum Disorder, who have been on a stable medication regime for the past month, who give their
  informed consent and who are aged over 18 will participate.
  Measures: Subjective assessments of sleep will include sleep diaries and questionnaires and objective assessment
  of sleep will include actigraphy. Actigraphy is a small wrist watch like device containing an accelerometer that can be
  used to record sleep/wake patterns. Actiwatches are noninvasive
  and allow assessment of sleep in the subjects own
  home. To examine the day to day relationship between sleep and symptoms we will use the experience sampling
  method, which consists of filling in questions about current states, numerous times a day for several days on an
  electronic device.
  Implications: this study will have strong implications for future development of sleep interventions and will answer
  important questions about sleep quality in this patient group
