The expression of early delusion and hallucination-like symptoms, known as positive schizotypy (PS), holds predictive power for later development of psychotic disorders. However, little is known about the psychological and emotional processes promoting the expression of PS during adolescent development. Our study's objective was to examine the nature of the relationships between adolescent PS and two dimensions previously identified to contribute to adult positive symptoms of psychosis, metacognitive beliefs and anxiety. Using a structural equation modeling design, data from self-report questionnaires measuring anxiety, metacognitive beliefs, and PS were collected from 179 adolescents aged 12 to 19 years. Our results indicate that although metacognitive beliefs significantly influence adolescent PS and anxiety, maladaptive contradictory metacognitive beliefs specifically potentiate positive schizotypal expression in hallucination-prone adolescents. Furthermore, we observe that PS and anxiety entertain reciprocal relationships. These findings suggest that relationships between metacognitive beliefs, anxiety, and PS can already be observed during adolescence. [less ▲]

Traumatic events have predicted depressive symptoms. Despite this consensus, it remains unclear as to whether the relationship between trauma and depression is consistently mediated by a negative cognitive schema, such as low self-esteem, or whether trauma influences mood independently of low self-esteem. This study tested these relationships while considering depressive symptom types. One hundred thirty-two students reported the number of traumatic events experienced and self-esteem and depression levels. Results indicated 2 depressive symptom types: "cognitive-affective" and "somatic." Structural Equation Modeling tested an unmediated path from trauma to depressive symptoms and a path mediated by self-esteem. Results supported the unmediated relationship between trauma and "cognitive-affective" depressive symptoms, and did not support mediation by self-esteem. Findings are discussed in view of a dimensional rather than categorical approach to depression, and in consideration of alternative symptom clusters resulting from trauma in addition to those captured by posttraumatic stress disorder.
