Abstract

Abstract
This thesis was designed to explore the nature of risk-taking behaviour in people
diagnosed with Bipolar Disorder (BD). Research has traditionally attributed risk-taking
behaviour in BD to difficulties in impulse control. Nonetheless, impulsivity remains
predominantly measured using self-report questionnaires, with dubious validity. The links
between impulsivity and risk-taking have also been challenged by new research in the field of
decision-making suggesting a different conceptualisation of this often misunderstood set of
behaviours. In particular, Fuzzy Trace Theory (FTT) offers an interesting framework to
understand risk-taking as a “rational/deliberate” act, rather than an impulsive one, providing
evidence for a “reasoned route” to risk-taking.
This piece of research comprised of a systematic review, an empirical paper and a
critical appraisal. The aim of the systematic review was to clarify whether there is consistent
evidence to suggest that risk-taking behaviours are more prevalent in people diagnosed with
BD compared to controls. Clinical and demographic predictors of risk-taking in BD were
also explored. The research paper aimed at characterising a group of people with BD in the
context of FTT and to explore whether measures of FTT were predictive of higher risk-taking
tendencies after controlling for impulsivity and mood. Finally, the critical appraisal aimed at
discussing the dilemma of conducting quantitative research as a trainee clinical psychologist.
The review suggested that people diagnosed with BD are more likely to engage in
risk-taking behaviour, but that this is dependent on mood state and mainly prevalent during
states of mania. Some evidence in support of clinical and demographic predictors of risktaking
in BD was also found. The empirical paper also supported the hypothesis that FTT
predicts risk-taking behaviour, even after accounting for the effects of mood and impulsivity.
The findings were discussed in relation to previous research on the topic
