Usability Testing Screening Questionnaire
Thank you for your interest in our usability testing study. Please read the following information and click “Continue to questions” at the bottom of this page.
What is the purpose of this study?
This study aims to understand how people diagnosed with Post-Traumatic Stress Disorder (PTSD) use the Modius Spero device in a typical home-use setting. Our goal is to ensure the device is easy to understand, simple to operate, and safe to use without additional support. Your feedback will help improve instructions, labelling, and usability for future users.
Location
The study will take place in central Belfast, and full details of the exact location will be provided to you in advance of your session.
What will happen if I take part?
You will attend a single session lasting around 30-45 minutes. During this session, you will:
- Use the Modius Spero device in a simulated home-use environment.
- Complete a series of common tasks (e.g., placing the pads, starting and stopping stimulation, interpreting device indicators, charging the device).
- Follow only the Instructions for Use provided to real users.
- Be observed by the researcher, who will take notes on ease of use and any questions you might have.
- Take part in a short interview about your experience.
- Complete a short questionnaire about usability and comprehension.
The session may be video-recorded to help with later analysis. You will have the option to agree or decline to allow these recordings to be used for communication or presentation purposes. Declining will not affect your ability to take part.
Screening
We aim to include approximately 15 adults aged 18 yrs or older with a PTSD diagnosis across a range of ages, genders, and levels of familiarity with technology.
We need to collect some information to determine if you’re suitable for the study.
All responses will be used for screening purposes only and will be kept confidential.
If many people meet the eligibility criteria, we will choose participants based on the needs of the study. This includes making sure we have a balanced mix of participant types.
To ensure this balance, we will:
- Review all eligible responses,
- Aim for a diverse sample across factors such as age range, gender, and technology experience, and
- Select a small number of people from each group so we include a range of perspectives.
The session may be video-recorded to help with later analysis. You will have the option to agree or decline to allow these recordings to be used for communication or presentation purposes. Declining will not affect your ability to take part.
To ensure a balanced mix of participants, meeting the eligibility criteria does not guarantee a place in the study.
Selected participants will receive a £100 gift voucher on completion as a thank you and in lieu of incurred expenses.
