Thought suppression and self-injurious thoughts and behaviors


, : Thought suppression and self-injurious thoughts and behaviors. Behaviour Research and Therapy 45(8): 1957-1965

This study proposes and tests a theoretical model suggesting that the propensity to suppress unwanted thoughts is associated with an increased presence and frequency of self-injurious thoughts and behaviors (SITB). In the model, propensity to suppress unwanted thoughts is hypothesized to be a cognitive mediator of the relationship between emotional reactivity and SITB, and is expected to be related to the extent to which SITB is initiated to escape from aversive emotions. Results of this cross-sectional study of adolescents (N = 87) revealed that the self-reported propensity to suppress unwanted thoughts is associated with the presence and frequency of non-suicidal self-injury (NSSI), suicidal ideation, and suicide attempts. Further-more, thought suppression partially mediates the relationship between emotional reactivity and the frequency of NSSI and suicidal ideation. Finally, adolescents with a higher tendency to suppress unwanted thoughts report engaging in NSSI in order to reduce aversive emotions rather than for social communication. Results are discussed within the framework of the negative reinforcement function of SITB.

The effect of impurities in a two-dimensional lattice of coupled nonlinear chaotic oscillators and their ability to control the dynamical behavior of the system are studied. We show that a single impurity can produce synchronized spatiotemporal pa...

Background & Aims: Studies on hepatitis C virus (HCV) quasispecies dynamics in the natural course of infection are rare owing to difficulties in obtaining samples from the early phase of infection.
