Feasibility Trial i-Sleep & BioClock Intervention

Students often suffer from sleep problems and circadian rhythm disruptions which affect their mental health and daily functioning. The aim of this project is to develop, implement and evaluate an e-health intervention that targets the biological clock and improves the sleep patterns of university students in order to prevent the development or exacerbation of mental health problems. The investigators will assess the feasibility, usability and acceptability of the intervention in this pilot trial.

Treatment and study plan

i-Sleep & BioClock Intervention

Behavioral

The 'i-Sleep & BioClock' intervention aims at improving sleep and the biological clock among university students. It is incorporates evidence-based techniques such as cognitive behavioural therapy for insomnia (CBTi). The intervention has a duration of 5 weeks and consists of five modules:

  • psychoeducation on insomnia, sleep hygiene and the biological clock,
  • stimulus control and sleep restriction therapy,
  • worrying and relaxation exercises,
  • cognitive therapy to change dysfunctional thoughts about sleep, and
  • summary module, relapse prevention, and plan for the future.

The intervention is supported by e-coaches who give personalized written feedback. Students will fill in a sleep & light exposure diary daily.

Primary outcomes

  1. Insomnia Severity Index

    Time frame: Change from baseline (T0) to 7 weeks after baseline (T1)

    7-item self-report instrument to assess insomnia severity, scores 0-28, higher scores indicating more insomnia severity

Secondary outcomes

  1. Sleep and light exposure diary

    Time frame: Change from week 0 (7 days prior to intervention period) to week 8 (7 days after T1)

    This diary includes measures such as sleep efficiency, sleep onset latency, total sleep time, wake after sleep onset, number of awakenings, early morning awakening, time spent outside, screen use before bedtime)

  2. Munich Chronotype Questionnaire (MCTQ)

    Time frame: Change from baseline (T0) to 7 weeks after baseline (T1)

    Self-rated scale to assess individual phase of entrainment on work and work-free days, Addresses questions about: bedtime, time spent in bed awake before deciding to turn off the lights, how long it takes to fall asleep, wake up time, get up time on work and work-free days. MCTQ uses the midpoint between sleep on- and offset on free days (mid-sleep on free days, MSF) to assess chronotype

  3. Patient Health Questionnaire (PHQ-9)

    Time frame: Change from baseline (T0) to 7 weeks after baseline (T1)

    9-items self-report instrument for severity of depressive symptoms, scores ranging from 0-27, higher scores indicating more severe depression

  4. Generalised Anxiety Disorder scale (GAD-7)

    Time frame: Change from baseline (T0) to 7 weeks after baseline (T1)

    7-items self-report instrument for severity of anxiety symptoms, scores ranging from 0-21, higher scores indicating more severe anxiety

  5. Work and Social Adjustment Scale (WSAS)

    Time frame: Change from baseline (T0) to 7 weeks after baseline (T1)

    5-item self-report instrument for impairment of functioning, scores ranging from 0-40, higher scores indicating more impairment in functioning

  6. Mental Health Quality of Life questionnaire (MHQoL)

    Time frame: Change from baseline (T0) to 7 weeks after baseline (T1)

    7-item self report instrument for quality of life measure for use in people with mental health problems, scores ranging from 0-21, higher scores indicating higher quality of life, and MHQoL-VAS visual scale ranging from 0 (worst imaginable psychological wellbeing) to 10 (best imaginable psychological wellbeing)

Other outcomes

  1. Client Satisfaction Questionnaire (CSQ-8)

    Time frame: 7 weeks after baseline (T1)

    8-item self-report questionnaire for client satisfaction with services, total score ranging from 8-32, higher indicating higher satisfaction

  2. System Usability Scale (SUS-10)

    Time frame: 7 weeks after baseline (T1)

    10-item self-report scale for system usability, five response options for respondents; from strongly agree to strongly disagree, scores ranging from 0-40, higher scores indicating better system usability

  3. Working Alliance Inventory for guided Internet interventions (WAI-I)

    Time frame: 7 weeks after baseline (T1)

    12-item self-report instrument to capture alliance in guided Internet interventions, 5-point Likert scale ranging from 1 (never) to 5 (always), scores ranging from 12-60, higher scores indicating better alliance

  4. Acceptability and usability of the sleep & light exposure diary

    Time frame: 7 weeks after baseline (T1)

    11 items on the sleep & light exposure diary, 5 point Likert Scale, scores ranging from 0-44, higher scores indicating better usability and acceptability, one visual scale on usefulness of the diary, 0 (not at all useful) to 10 (Very much useful)

  5. Adherence to the program

    Time frame: Through study completion, on average 7 weeks

    Will be measured by the total number of completed modules and lessons, time spent in the platform, and the number of logins
