Feasibility of a Bedtime Variability Protocol

November 5, 2024 updated by: Emily Hohman, Penn State University
The purpose of this study is to find out if parents and children 6-10 years old are willing and able to follow a protocol to be used to study the effects of short and/or variable sleep in children. During each of three, one-week long periods, parents will have their child follow one of the following bedtime schedules: 1) habitual bedtime; 2) 1 hour later bedtime; or 3) variable bedtime (+/- 1 hour of habitual bedtime each day). Children will wear a sleep tracker and parents will complete daily diaries. Participants will answer questions about their experiences completing the protocol.

Conditions

Conditions

Detailed Description

The purpose of this study is to find out if parents and children 6-10 years old are willing and able to follow a protocol to be used to study the effects of short and/or variable sleep in children. Children with medical conditions or taking medications affecting sleep, or children who do not have a regular bedtime, will be excluded. During each of three, one-week long periods, parents will have their child follow one of the following bedtime schedules: 1) habitual bedtime; 2) 1 hour later bedtime; or 3) variable bedtime (+/- 1 hour of habitual bedtime each day). Children will wear a sleep tracker and parents will complete daily diaries. Participants will answer questions about their experiences completing the protocol. Participants will attend an initial enrollment visit to complete consent and receive instruction on the protocol. Participants will then complete the three experimental conditions in a randomized, counterbalanced order. Participants will complete a phone or Zoom check in at the end of the first two conditions, and an in-person or Zoom visit at the end of the third condition where their opinions about the protocol feasibility and acceptability will be assessed, answer any questions, and provide them instruction for the next condition (when applicable).

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Child age 6-10 years
  • Parent age 18 years or older
  • Child has a regular bedtime (goes to bed within 30 minutes of the same time on 5 or more days per week)

Exclusion Criteria:

  • Child has a medical condition impacting sleep (e.g., narcolepsy, sleep apnea)
  • Child has a developmental disorder or delay (e.g., autism, Down syndrome)
  • Child regularly takes supplements or medications (prescription or over the counter) for sleep, such as melatonin or antihistamines
  • Not English speaking

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Habitual bedtime
For one week, children will follow their habitual bedtime.
Experimental: Late bedtime
For one week, children will go to bed one hour later than their habitual bedtime
Behavioral: Late bedtime
Participants will go to bed 1 hour later than their habitual bedtime
Experimental: Variable bedtime
For one week, children will go to bed at a prescribed time that will vary each day within +/- 1 hour of habitual bedtime.
Behavioral: Variable bedtime
Participants will go to bed at a prescribed time that varies each day within +/-1 hour of habitual bedtime

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adherence to bedtime protocol
Time Frame: Daily during each of the 3, one-week intervention periods
Parents will report on the time their child went to bed
Daily during each of the 3, one-week intervention periods

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Parent perception of feasibility of following the protocol (semi-structured interview)
Time Frame: At the end of 3 week study
Parents will provide qualitative answers to questions about their perceptions of following the protocol, including but not limited to whether the protocol was easy to follow, disruptive to their life, disruptive to their child's life.
At the end of 3 week study
Sleep duration
Time Frame: Daily during each of the 3, one-week intervention period
Child sleep duration during each intervention period, measured by actigraphy
Daily during each of the 3, one-week intervention period
