Key Findings

  • 01A 48-item scale measuring nine constructs of OTT platform usability was developed and validated.
  • 02Privacy and Design factors significantly influenced user satisfaction, continued intention to use, and brand loyalty.
02

Application

Design takeaway

When designing digital platforms, particularly streaming services, focus on making privacy features prominent and ensure the overall design is both functional and aesthetically pleasing, as these directly impact user satisfaction and continued engagement.

How to apply

Utilize the identified nine constructs (Accessibility and Customization, Account Management, Data Entry and Search, Branding, Privacy, Navigation, Help, Content, and Design) as a checklist or framework for evaluating the usability of any digital interface, paying particular attention to privacy and design elements.

Project actions

  • 01When developing a usability scale, clearly define the constructs you intend to measure before creating survey items.
  • 02Consider conducting both exploratory and confirmatory factor analysis to ensure the robustness of your measurement instrument.

Method & Evidence

AimTo develop and validate a comprehensive measurement scale for assessing the usability of Over-the-Top (OTT) streaming platforms.
MethodScale Development and Validation (Survey Research)
ProcedureThe study conceptualized OTT platform usability into nine constructs (Accessibility and Customization, Account Management, Data Entry and Search, Branding, Privacy, Navigation, Help, Content, and Design). A 48-item scale was developed based on these constructs. The scale's measurement properties were evaluated using exploratory factor analysis (EFA) with 650 participants. Subsequently, confirmatory factor analysis (CFA) was applied with 600 participants to validate the scale. Nomological validation was also performed by examining the scale's relationship with user satisfaction, continued intention to use, and brand loyalty.

Strengths & Limitations

Strengths

  • +Rigorous scale development and validation process using established statistical techniques (EFA and CFA).
  • +Nomological validation demonstrating the scale's predictive power for key user outcomes.

Limitations

The sample size and demographic diversity of participants can impact the generalizability of your findings. Ensure your chosen context for testing is representative of the intended user base.

Reliability & validity

The study employed both exploratory and confirmatory factor analysis to establish construct validity and reliability. Nomological validation further supported the scale's validity by demonstrating expected relationships with related constructs.

Think critically

How might the specific design guidelines (e.g., Apple tvOS) used in this study influence the identified usability constructs, and would a similar scale yield the same results if based on different platform guidelines?

05

Design Principles

"Usability is a multi-faceted construct that can be systematically measured and improved by focusing on key areas such as privacy, design, navigation, and content accessibility."

Understanding and quantifying user experience is crucial for designing engaging and effective digital products. This research provides a tool to identify specific areas of strength and weakness in OTT platforms, enabling designers to make data-driven improvements that enhance user satisfaction and retention.

06

What This Means for Your Design

Researchers created a detailed questionnaire to check how easy and good to use streaming services like Netflix are. They found that how safe people feel their data is and how nice the app looks are super important for people to keep using the service.

How to use in your project

  • 1.Reference the methodology for scale development and validation when designing your own user research instruments.
  • 2.Use the identified usability constructs as a basis for your own user testing or survey design.
