  This paper describes the first stage of the ongoing development of two scales
to measure online wellbeing and trust, based on the results of a series of
workshops with younger and older adults. The first, the Online Wellbeing Scale
includes subscales covering both psychological, or eudaimonic, wellbeing and
subjective, or hedonic, wellbeing, as well as digital literacy and online
activity; the overall aim is to understand how a user's online experiences
affect their wellbeing. The second scale, the Trust Index includes three
subscales covering the importance of trust to the user, trusting beliefs, and
contextual factors; the aim for this scale is to examine trust in online
algorithm-driven systems. The scales will be used together to aid researchers
in understanding how trust (or lack of trust) relates to overall wellbeing
online. They will also contribute to the development of a suite of tools for
empowering users to negotiate issues of trust online, as well as in designing
guidelines for the inclusion of trust considerations in the development of
online algorithm-driven systems. The next step is to release the prototype
scales developed as a result of this pilot in a large online study in to
validate the measures.
