Baseline
What is the baseline condition?
During this phase, parents were instructed not to change bedtime routines or responses to sleep-related behaviours, allowing natural sleep patterns to be observed.
How many participants were there?
2
What does IOA stand for?
Interobserver Agreement
Sleep problems are highly common in children with what diagnosis?
ASD
What is a Functional Behavioural Assessment FBA?
This assessment process was used to identify the function maintaining sleep-interfering behaviours before creating individualized interventions.
What were the parents informed to do for the baseline condition?
During this phase, parents were instructed not to change bedtime routines or responses to sleep-related behaviours, allowing natural sleep patterns to be observed.
What were the names of the participants?
What was used to check IOA against parent sleep diaries?
Video-somnography (VSG)
Poor sleep negatively affects a child’s what type of functioning?
Daytime functioning
What is an ABAB design?
This experimental design used with Matthew included a baseline, intervention, partial reversal, and reintroduction of the intervention, providing stronger evidence of a functional relationship.
What are 14 days for Matthew and 27 days for Mirasol?
The baseline phase lasted this many days for Matthew and this many days for Mirasol.
What were the ages of the participants at the time of the study?
4 years 2 months and 10 years 10 month
What is the IOA formula?
Agreements ÷ (Agreements + Disagreements) ×100
Name one way poor sleep affects the family.
It disrupts family routines or affects parental well-being.
What type of experimental design was used for Mirasol?
AB design (Baseline → Intervention)
Why is collecting baseline data essential in a single-case design study?
It provides a comparison point to determine whether changes are due to the intervention.
Why couldnt there be further maintained data collected for marisol?
She was temporarily placed in a residential home for her aggression
Did Matthew’s caregiver interactions increase or decrease after intervention?
decrease
Why is it important to identify the function of sleep-interfering behaviors in children with ASD?
Because treating the function leads to more effective and meaningful long-term improvement than just reducing surface behaviors.
What was the main purpose of using a Functional Behavioral Assessment (FBA) in this study?
To identify the function of sleep-interfering behaviors and guide individualized treatment.
What would it mean if behavior improved during baseline before the intervention was introduced?
It would weaken the argument that the intervention caused the change.
What did Mathew struggle with?
Frequent, Curtain Calls, and Night Awakenings
What sleep variable improved the most overall?
Nighttime awakenings (NWs)
What broader outcome does improving sleep aim to enhance for both the child and family?
Overall quality of life and reduced family stress.
Why were individualized treatment packages necessary instead of using the same intervention for both children?
Child’s sleep-interfering behaviors were maintained by different functions, identified through the FBA, so they required different treatment packages
