About this study

Official title: Developmental Status, Sensory Processing, and Sleep Quality in Preschool Children Across Different Caregiving Models

This observational study aims to examine developmental status, sensory processing, and sleep quality in preschool children aged 3 to 6 years across different caregiving models. Children raised primarily by first-degree relatives, second-degree relatives, caregivers, or in daycare settings will be compared. Data will be collected using the Denver II Developmental Screening Test, the Dunn Sensory Profile, and the Tayside Children's Sleep Questionnaire. The study will also evaluate the relationships among developmental status, sensory processing, and sleep quality, and explore whether caregiving model is associated with differences in these outcomes.

Read the detailed description

This observational study is designed to investigate whether different caregiving models are associated with differences in developmental status, sensory processing, and sleep quality in preschool children. Early childhood development is influenced by both biological and environmental factors, and caregiving context is considered one of the important environmental influences shaping children's developmental outcomes. In this study, caregiving model refers to the primary care arrangement in which the child has been raised, including care by first-degree relatives, second-degree relatives, a paid caregiver, or a daycare setting.

Participants will include preschool children between 3 and 6 years of age living in Istanbul. Eligible participants must have been raised within the same caregiving model for at least the previous 6 months, and parents must provide informed consent. Children with previously diagnosed neurological, developmental, or psychiatric disorders, those currently receiving treatment for sensory, sleep, or developmental problems, or those unable to complete the assessment process will be excluded.

Data will be collected through parent-report forms and standardized assessment tools. Developmental status will be assessed using the Denver II Developmental Screening Test, sensory processing will be evaluated using the Dunn Sensory Profile, and sleep quality will be assessed using the Tayside Children's Sleep Questionnaire. Recruitment will be conducted through social media announcements, and eligible families will be invited for face-to-face assessment in the Ergotherapy Department laboratory at Fenerbahçe University.

The study plans to compare four caregiving groups and to analyze whether there are significant differences between groups in developmental status, sensory processing, and sleep quality. In addition, correlations among these three outcome domains will be examined. Statistical analyses will be conducted using SPSS, with appropriate parametric or nonparametric tests depending on data distribution. The findings are expected to contribute to a better understanding of how caregiving environments may be related to child development and functional outcomes in early childhood.

Study groupRoleWhat they receive
First-Degree Relative CarePreschool children aged 3 to 6 years whose primary caregiving model for at least the past 6 months has been provided by first-degree relatives, including mother and/or father.
Second-Degree Relative CarePreschool children aged 3 to 6 years whose primary caregiving model for at least the past 6 months has been provided by second-degree relatives, such as grandparents, aunts, or uncles.
Paid Caregiver CarePreschool children aged 3 to 6 years whose primary caregiving model for at least the past 6 months has been provided by a paid caregiver or nanny.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Developmental status assessed by the Denver II Developmental Screening Test

    Developmental status of preschool children will be assessed using the Denver II Developmental Screening Test. The Denver II is a developmental screening instrument and does not yield a single total numeric score. Results will be reported using standard test interpretation categories such as normal, suspect, or untestable.

    Measured: At baseline (single assessment)

  2. Sensory processing assessed by the Dunn Sensory Profile

    Sensory processing patterns of preschool children will be assessed using the Child Sensory Profile 2, a caregiver-reported standardized measure of sensory processing. Outcomes will be reported as raw scores for the relevant quadrants and/or sensory section scores, with corresponding normative classifications. Higher raw scores indicate more frequent sensory processing behaviors and do not necessarily indicate a better outcome.

    Measured: At baseline (single assessment)

  3. Sleep quality assessed by the Tayside Children's Sleep Questionnaire

    Sleep quality of preschool children will be assessed using the Tayside Children's Sleep Questionnaire, a parent-reported screening instrument for disorders of initiating and maintaining sleep in young children. The total score is calculated by summing the first 9 items. Scores range from 0 to 36, with higher scores indicating more sleep problems and therefore a worse outcome. A total score of 8 or higher suggests possible sleep disturbance.

    Measured: At baseline (single assessment)

Questions about this trial

What is this clinical trial studying?

An observational study of Child Development and Sensory Processing, run by Fenerbahce University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Developmental status assessed by the Denver II Developmental Screening Test (time frame: At baseline (single assessment)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2026.
