Objectives. This thesis aimed to examine a series of personality and cognitive factors as prospective predictors of suicidal thinking and psychological distress. A secondary objective was to examine any causal relationship between rumination and attentional biases. Method. In order to achieve the above objectives, a series of four studies were conducted. Studies one and three were prospective studies, using analogue samples, to examine the role of personality and cognitive factors in distress and suicidal thinking. In addition, study one also investigated the effect on attentional bias of manipulating rumination. Study two was an experimental study in which two different methods of manipulating attentional bias were piloted. The final study in this thesis employed a clinical sample of general hospital parasuicide patients to investigate whether relationships between personality and cognitive factors were replicable in a clinical population. Results. The personality and cognitive factors understudy were investigated within a research framework to examine their interactive effects. Hierarchical regression analyses revealed a number of moderating and mediating relationships between these personality and cognitive factors to prospectively predict both suicidal thinking and psychological distress. In addition, rumination was found to have a causal influence on positive attentional bias. Conclusions. Evidence from this thesis links personality and cognitive factors to both suicidal thinking and psychological distress in a series of moderating and mediating relationships. These are discussed in relation to the possible theoretical and clinical implications.
