Estimating food portions. Influence of unit number, meal type and energy density. (2013)
Journal Article
E, A., I, S., J, D., & SA, J. (2013). Estimating food portions. Influence of unit number, meal type and energy density. Appetite, 71, 95-103. https://doi.org/10.1016/j.appet.2013.07.012

Estimating how much is appropriate to consume can be difficult, especially for foods presented in multiple units, those with ambiguous energy content and for snacks. This study tested the hypothesis that the number of units (single vs. multi-unit), m... Read More about Estimating food portions. Influence of unit number, meal type and energy density..

This study explored the impact of beliefs about mood swings on symptomatic outcome in bipolar disorder (BD). Ninety-one people with BD completed a Brief Illness Perception Questionnaire at baseline. Outcome was measured using weekly measures of mood... Read More about The role of beliefs about mood swings in determining outcome in bipolar disorder.

An online randomised controlled trial to assess the feasibility, acceptability and potential effectiveness of “Living with Bipolar”: A web-based self-management intervention for Bipolar Disorder: Trial design and protocol (2012)
Journal Article
Todd, N. J., Solis-Trapala, I., Jones, S. H., & Lobban, F. A. (2012). An online randomised controlled trial to assess the feasibility, acceptability and potential effectiveness of “Living with Bipolar”: A web-based self-management intervention for Bipolar Disorder: Trial design and protocol.

Background
Bipolar Disorder (BD) is a common and severe form of mental illness. Pharmacotherapy is the main treatment offered, but has limited effectiveness, and there is increasing evidence that people with BD respond well to psychological interven...

Multidimensional latent markov models in a developmental study of inhibitory control and attentional flexibility in early childhood (2010)
Journal Article
Bartolucci, F., & Solis-Trapala, I. L. (2010). Multidimensional latent markov models in a developmental study of inhibitory control and attentional flexibility in early childhood. Psychometrika, 75, 725-743. https://doi.org/10.1007/s11336-010-9177-1

We demonstrate the use of a multidimensional extension of the latent Markov model to analyse data from studies with repeated binary responses in developmental psychology. In particular, we consider an experiment based on a battery of tests which was...

The (mis)classification of chemo-fog – methodological inconsistencies in the investigation of cognitive impairment after chemotherapy (2005)
Journal Article

Background
A growing number of studies report cognitive impairment after chemotherapy; indeed the phenomenon of chemo-fog is now almost universally accepted. We are concerned however that there is little if any consistency in the way in which patien...

Regression analysis of overdispersed correlated count data with subject specific covariates. (2005)
Journal Article

A robust likelihood approach for the analysis of overdispersed correlated count data that takes into account cluster varying covariates is proposed. We emphasise two characteristics of the proposed method: That the correlation structure satisfies the...
