Insights
Experts reached a consensus on defining optimal bedtime routines for young children (ages 2-8). New measurement tools were developed to assess these crucial family activities and their impact on child development.
Area of Science:
- Child Development
- Family Health
- Behavioral Science
Background:
- Bedtime routines are vital family activities influencing child wellbeing, development, and health.
- Optimal bedtime routines lack a clear definition and standardized measurement, hindering research and practice.
- This study addresses the need for expert consensus on defining and measuring bedtime routines.
Purpose of the Study:
- To achieve expert consensus on a definition of optimal bedtime routines for families with young children (ages 2-8).
- To propose reliable measurement tools for assessing bedtime routines.
- To establish a foundation for understanding the behavioral determinants of child health and development.
Main Methods:
- A four-step DELPHI process involving 59 experts from diverse scientific, health, and social care backgrounds.
- Iterative refinement of the definition and measurement of bedtime routines over three formal DELPHI rounds.
- Validation of the proposed measurement against existing data post-DELPHI process.
Main Results:
- A holistic definition of optimal bedtime routines for children aged 2-8 was achieved with 70% expert agreement.
- Two measurement approaches were proposed: a static (one-off) and a dynamic (7-night) method.
- Bland-Altman analysis indicated agreement between the static and dynamic measurements, suggesting they can be used interchangeably.
Conclusions:
- The established definition and proposed measurements represent a significant advancement in quantifying bedtime routines.
- These tools are crucial for capturing a key behavioral determinant linked to important child health and developmental outcomes.
- Further research can utilize these consensus-based definitions and measurements to explore the impact of bedtime routines.
Introduction:
Bedtime routines are one of the most common family activities. They affect children' wellbeing, development and health. Despite their importance, there is limited evidence and agreement on what constitutes an optimal bedtime routine. This study aims to reach expert consensus on a definition of optimal bedtime routines and to propose a measurement for bedtime routines.
Method:
Four-step DELPHI process completed between February and March 2020 with 59 experts from different scientific, health and social care backgrounds. The DELPHI process started with an expert discussion group and then continued with 3 formal DELPHI rounds during which different elements of the definition and measurement of bedtime routines were iteratively refined. The proposed measurement of bedtime routines was then validated against existing data following the end of the DELPHI process.
Results:
At the end of the four round DELPHI process and with a consistent 70% agreement level, a holistic definition of bedtime routines for families with young children between the ages of 2 and 8 years was achieved. Additionally, two approaches for measuring bedtime routines, one static (one-off) and one dynamic (over a 7-night period) are proposed following the end of the DELPHI process. A Bland-Altman difference plot was also calculated and visually examined showing agreement between the measurements that could allow them to be used interchangeably.
Discussion:
Both the definition and the proposed measurements of bedtime routines are an important, initial step towards capturing a behavioural determinant of important health and developmental outcomes in children.
