The purpose of this work was to study the relationship between reported traumatic experiences in childhood and positive psychotic symptoms. We hypothesized that dissociative experiences were potential mediators between childhood trauma and hallucinations, but not delusions. The sample comprised 71 patients diagnosed with psychoses. They were assessed with the Dissociative Experiences Scale (DES-II; Carlson & Putnam, 1993), a questionnaire on trauma (TQ; Davidson, Hughes, & Blazer, 1990), and the Positive and Negative Syndrome Scale (PANSS; Kay, Opler, & Lindenmayer, 1988) delusions and hallucinations items. The results showed that childhood trauma was positively associated with the dissociation scale scores (r = .40) and also the hallucination (r = .36) and delusions scale scores (r = .32). Furthermore, it was demonstrated that the dissociation variable was a potential mediator between childhood trauma and hallucinations, but not between childhood trauma and delusions. Of the 3 DES-II factors, only depersonalization showed a mediating relationship between childhood trauma and hallucinations. The main conclusion is that the impact of childhood trauma on hallucinations may not simply be direct, but mediated by dissociative experiences, especially depersonalization. Clinical implications are also briefly discussed.

We discuss the role of metacognitive and dissociative variables in understanding hallucinations and suggest some approaches to their treatment.

A growing body of research on verbal hallucinations shows the importance of beliefs about and relationships with the voices for their pathological course. In particular, beliefs about the omnipotence of the voices and the need to control them, and relationships with them that involve efforts to resist or fi ght them, have shown themselves to be more pathogenic than effective. Likewise, treatments aimed at eliminating the voices, be they based on medication or 'traditional' cognitive-behavioural therapy, have not always been successful. A series of strategies focused on changing relationships with the voices instead of trying to eliminate them-including mindfulness, acceptance, experiential role plays and re-authoring lives-is emerging as a new perspective for the treatment of hallucinations. All of these strategies are based on the person, not on the syndrome, which also represents a new conception of the problem, in a phenomenological-social perspective, alternative to the predominant medical conception.

The purpose of this work was to study the potentially mediating role of certain dissociative factors, such as depersonalization, between self-focused attention and auditory hallucinations. A total of 59 patients diagnosed with schizophrenic disorder completed a self-focused attention scale ( M. F. Scheier & C. S. Carver, 1985 ), the Cambridge Depersonalization Scale (M. Sierra & G. E. Berrios, 2000), and the hallucination and delusion items on the Positive and Negative Syndrome Scale (S. R. Kay, L. A. Opler, & J. P. Lindenmayer, 1988). The results showed that self-focused attention correlated positively with auditory hallucinations, with delusions, and with depersonalization. It was also demonstrated that depersonalization has a mediating role between self-focused attention and auditory hallucinations but not delusions. In the discussion, the importance of dissociative processes in understanding the formation and maintenance of auditory hallucinations is suggested.

Recent contributions to the theoretical conception and empirical evaluation of schizophrenia in the light of phenomenology are opening the way to new perspectives in psychotherapy. The phenomenological conception understands schizophrenia as a disturbance of the basic sense of selfhood (ipseity) characterized by hyper-reflexivity and diminished sense of self. Evaluation consists of examining the anomalous self-experience in a series of domains, which makes the conception presented operable. On this basis, a phenomenologically informed psychotherapy is introduced. Its characteristics are pointed out and early intervention is reviewed (the last frontier in psychosis) from this perspective. Finally, a series of psychotherapies which, although they do not have a phenomenological origin, may be seen from that perspective, are re-examined. These are the narrative, mindfulness and acceptance and commitment therapies.
