Margaret’s research draws strongly from her dual backgrounds in Nursing and Clinical Psychology. Margaret’s doctorate developed a measure of anxiety in older adults using a mixed-methods approach. This measure is presently in use within Waitemata DHB and is undergoing further psychometric evaluation within this population.
Margaret’s knowledge of psychometrics and patient reported outcome measures has led to several further research collaborations within palliative care and mental health, including measure development and evaluation. Evaluation includes ensuring that the measure is accurate, and that the score on the measure is not disadvantaging groups due to factors unrelated to the domain reportedly measured. For example, determining whether the score on a pain measure is based on pain or another unrelated factor (e.g. cultural aspects) that may unfairly disadvantage the patient.
Margaret is currently supervising masters and doctoral students in psychology and nursing, in the areas of evaluating health related outcome measures, nurse wellbeing, and psychological treatment for cancer patients.
Margaret uses a mixed-methods approach to research, with particular strengths in confirmatory factor analysis and Rasch analysis.
