Psychopathological mediators between insecure attachment and psychotic features in a non-clinical sample: the role of depression and interpersonal sensitivity.

INTRODUCTION: Attachment styles represent a personality pattern critical to psychological health, with insecure attachment being a central factor in developing psychopathological characteristics of psychosis. However, its downstream psychopathological pathways remain unclear. This study aimed to investigate the putative psychopathological mediators in the relationship between insecure attachment and psychotic features in a non-clinical sample of university students. METHODS: We recruited two non-clinical samples for a total of 978 subjects, 324 males and 654 females, and administered the Relationship Questionnaire (RQ) to assess attachment styles and the Symptom Check-List 90 (SCL-90) to assess psychopathological symptoms. Moreover, the Paranoia and Psychoticism subscales of SCL-90 were combined and used as a measure of Psychosis (PSY). A mediation analysis model was carried out to establish the relationship among variables. RESULTS: Mediation analysis showed a total effect from RQ-Preoccupied and RQ-Fearful to PSY, respectively, 0.31 and 0.28. Direct effects from the SCL-90-R factor candidate mediator to PSY ranged from 0.51 for somatization to 0.72 for depression and 0.72 for interpersonal sensitivity. Indirect effects ranged from 0.08 for RQ-Preoccupied via hostility to 0.21 for RQ-Preoccupied via depression. DISCUSSION: Our results show that the effect of insecure attachment on psychosis features is differentially mediated by some psychopathological dimensions, being depression and interpersonal sensitivity the most relevant ones. PSY feature, therefore, is predicted by other specific symptoms in the psychological context of insecure primary relationships. CONCLUSIONS: From a preventive and clinical point of view, our results could be relevant in informing the early-stage psychological treatment of pre-psychotic states and, in general, people experiencing sub-threshold psychotic symptoms.

The impact of attachment styles and defense mechanisms on psychological distress in a non-clinical young adult sample: A path analysis.

INTRODUCTION: Insecure attachment styles and immature or neurotic defense mechanisms are related to psychological distress. However, their mutual interaction in influencing psychological distress deserves further investigation. METHODS: One-thousand-one-hundred-twenty-nine University students were evaluated using the Global Severity Index of Symptoms Check List 90-Revised for psychological distress, Relationship Questionnaire for attachment styles and Defense Style Questionnaire for defense mechanisms. Following exploratory analyses, a Path Analysis was performed with psychological distress as outcome. RESULTS: Fearful and preoccupied attachment styles had a substantial impact on psychological distress. About 30% of their effect was mediated by Immature and Neurotic defenses, with the former having the major effect. Dismissing attachment showed no substantial effect on psychological distress. Secure Attachment and Mature Defenses had a small protective effect on psychological distress, but their inclusion in the path model did not improve overall goodness-of-fit. Attachment style and defense mechanisms accounted for nearly 25% of the variance in psychological distress. CONCLUSIONS: The results showed that attachment styles and defense mechanisms have a substantial impact on psychological distress. The effect of attachment style is mediated by defense mechanisms. Individual differences in attachment style and defense mechanisms represent risk factors for psychological distress in young adults.
