A reliable and valid 11-item Likert scale can effectively gauge adult perceptions of orthodontic treatment across general views, adult-specific considerations, treatment outcomes, and retention. This user-centred design research insight is drawn from a 2020 study published in The Korean Journal of Orthodontics. Using Instrument development and psychometric validation with 406 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Develop and validate user perception instruments early in the design process to ensure your product or service aligns with user expectations and beliefs.

Key Findings
- 01A reliable and valid 11-item instrument was developed to measure adult perceptions of orthodontic treatment.
- 02The instrument covers four factors: general perception, perception for adults, treatment effects, and retention.
- 03Cronbach's alpha values indicated good internal consistency for the overall scale and its sub-factors.
Application
Design takeaway
Develop and validate user perception instruments early in the design process to ensure your product or service aligns with user expectations and beliefs.
How to apply
Use a Likert scale to ask users about their expectations, concerns, and perceived benefits related to a product or service, and analyze the data for reliability and validity.
Project actions
- 01When designing a product or service, consider how users will perceive it.
- 02Use surveys with Likert scales to gather user opinions and analyze the results for reliability (consistency) and validity (accuracy).
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Development of a psychometrically sound instrument.
- +Use of robust statistical methods for validation.
Limitations
The sample size might not be large enough for robust statistical analysis, and the survey might not capture all nuances of user perception.
Reliability & validity
Reliability was assessed using Cronbach's alpha, indicating internal consistency. Validity was established through exploratory and confirmatory factor analysis, ensuring the instrument measures the intended constructs.
Think critically
How might cultural differences influence the perception of orthodontic treatment, and how could a measurement instrument be adapted to account for these variations?
Design Principles
"Quantify user perception using validated instruments to inform design decisions."
Understanding user perception is crucial for the successful adoption and satisfaction with any product or service. For healthcare interventions like orthodontic treatment, accurately measuring patient perception can inform communication strategies, treatment planning, and ultimately improve patient engagement and outcomes.
What This Means for Your Design
This study created a reliable survey with 11 questions to measure how adults feel about getting braces or other orthodontic treatments. It helps understand their opinions on general aspects, adult-specific issues, expected results, and long-term success.
How to use in your project
- 1.Reference this study when discussing the importance of understanding user perception and how to measure it quantitatively.
- 2.Use the methodology as inspiration for developing your own user perception survey for your design project.
