Current research on sibling relationship quality is heavily skewed towards specific demographic groups, limiting its generalizability and applicability. This user-centred design research insight is drawn from a 2024 study published in Child Development. Using Evidence and gap mapping (egm) with 277 studies, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Actively seek out and integrate data from diverse populations to avoid design bias and ensure products and services are relevant and effective for all users.
Diverse Sibling Dynamics: A Gap in Understanding Relationship Quality
Current research on sibling relationship quality is heavily skewed towards specific demographic groups, limiting its generalizability and applicability.
Child Development · 2024
Key Findings
- 01The majority of studies on sibling relationship quality have focused on samples comprising predominantly White, middle-to-upper class, and/or two-caregiver families.
- 02Quantitative methods were used in nearly 85% of studies to assess sibling relationship quality across eight specific domains (conflict, warmth/affection, quality, cohesion, hostility, power/control, positive engagement, and conflict management).
- 03A substantial number of studies (122) examined sibling relationship quality as a predictor of various child outcomes.
Application
Design takeaway
Actively seek out and integrate data from diverse populations to avoid design bias and ensure products and services are relevant and effective for all users.
How to apply
When conducting user research for a new product or service aimed at children or families, intentionally recruit participants from a wide range of socioeconomic backgrounds, ethnicities, and family structures to ensure findings are representative.
Project actions
- 01When researching user needs, consider the diversity of your target audience and actively look for information that represents different backgrounds.
- 02If your project involves family dynamics, be mindful of the potential for bias in existing research and try to find studies that include diverse samples.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive synthesis of a large body of literature.
- +Systematic approach using Evidence and Gap Mapping.
Limitations
The original research synthesis is limited by the studies available; if certain groups were not studied, their dynamics cannot be mapped.
Reliability & validity
The reliability and validity of the EGM depend on the systematic and objective categorization of the included studies. The validity is strengthened by the large number of studies synthesized, but limited by the potential for publication bias and the quality of the original studies.
Think critically
How might the over-representation of certain family structures in research on sibling relationships influence the design of products intended for family use?
Design Principles
"Design for inclusivity by acknowledging and addressing demographic biases in foundational research."
Understanding the full spectrum of sibling relationships is crucial for designing interventions, educational programs, and even products that cater to diverse family structures and experiences. Ignoring underrepresented groups can lead to biased design solutions that fail to meet the needs of a significant portion of the population.
What This Means for Your Design
Most studies about how brothers and sisters get along only look at certain kinds of families, like white, middle-class ones. This means we don't fully understand how other families' sibling relationships work.
How to use in your project
- 1.Reference this study to highlight the importance of diverse user sampling in your design project's research phase.
- 2.Use the identified gaps in research to justify your own user research methodology, emphasizing how you will address underrepresented groups.

Paragraph starter
The synthesis of literature on sibling relationship quality reveals a significant bias towards samples comprising predominantly White, middle-to-upper class, and/or two-caregiver families. This highlights a critical need for design projects to actively pursue user research that includes diverse demographic groups to ensure the developed solutions are inclusive and effective for a broader population.
