Workstream Lead: Dr Lee Hulbert-Williams

Over the past fifteen years, Lee has led on a wide range of psychometric measurement research projects, for a range of different populations, and psychological outcomes. The importance of developing and validating robust and accurate ways to measure psychological constructs and behaviour — for both clinical practice and for use in research — led us to identify psychological measurement as one of our core work streams in the Centre.

Our completed projects over the last few years have led to publication of the following measures, all of which are free to use and in the public domain:

> the Bangor Life Events Schedule for Intellectual Disabilities (BLESID)

> the British-English version of the Food Craving Inventory (FCI-UK)

> the Mindful Eating Scale (MES)

> the Psychological Impact of Cancer Scale (PIC)

 

Current Projects

Testing the psychometric validity of the Acceptance and Action Questionnaire: The Acceptance and Action Questionnaire (AAQ-II; Bond et al. 2011) is the most widely used measure of psychological flexibility. Whilst there is existing evidence of its reliability and validity, some psychometric questions remain. By combining Item Response Theory (IRT) with more traditional psychometric approaches, we aimed to further validate the measure and outline an ultra-brief version suitable for daily recording in both research and practice.

The Three Selves Scale: Relational Frame Theory (RFT) provides a function conceptualisation of the self that is tripartite; including self-as-content, self-as process, and self-as-context. Previously validated measures fail to psychometrically distinguish these three components, but a scale that does so is important for both research and applied practice. This study aims to develop the Three Selves Scale. Project Lead: Nick Hulbert-Williams

The Multi-Attitudinal Stigma Scale: There are many scales that measure varying types of specific stigma (e.g. self-stigma, stigma toward mental illness, homonegativity, etc.). However, many of these are dated and use language not in common use today. Additionally, there is no modern scale that measures stigma toward many different populations in a flexible manner where the researcher can adjust the presentation of the scale to refer to one potentially stigmatised group or another. This study aims to create and validate a questionnaire that measures participants’ stigmatised attitudes towards any given population. Project Lead: Sabrina Norwood

Measuring self-authenticity: The concept of self-authenticity involves being aware of, and engaged with, personal values and values-based living. These are crucial constructs in psychological interventions, most notably in Acceptance and Commitment Therapy (ACT). This study aims to develop a novel psychometric that measures self-authenticity according to contemporary theoretical frameworks. Project Lead: Tim Cartwright

Improving our assessment of subjective wellbeing: One of Lee’s primary research interests is in subjective well-being — from stress and depression at one end of the continuum, to happiness and contentment at the other. However, there are very few psychometric tools that reliably capture both end of this continuum in a single measurement. This work aims to develop such a tool with both research and applied practice utility. Project Lead: Lee Hulbert-Williams
