Abstract
1. Introduction
1.1. Trauma and Post-Traumatic Stress in Adolescents
1.2. Time Perspective Theory
1.3. Time Perspective Theory Applied to Post-Traumatic Stress
1.4. Associations Between Post-Traumatic Stress, Time Perspective and Cannabis Use
1.5. Aim of This Study and Hypotheses
- Adolescents with PTSS show an imbalanced TP characterized by high orientations towards Past Negative and Present Fatalistic and low orientation towards Past Positive and Future.
- The relationship between EPTE and PTSS is mediated by DBTP analogous to the model proposed by Tomich et al. (2022) (see Figure 1).
- The relationship between EPTE and cannabis use is mediated by PTSS and DBTP serially (see Figure 2).
