The relationship between dissociation and cognitive abilities remains controversial. Empirical studies have reported positive, negative and non-existent associations between dissociation and cognition. These inconsistent results may be due to the fact that the studies focused mainly on trait dissociation, while dissociation is not stable but transient. After validating the French version of the Clinician Administered Dissociative States Scale (CADSS), the aim of the present study was to evaluate the relationship between state dissociation and cognitive abilities. We recruited 83 patients suffering from post-traumatic stress disorder (PTSD) and assessed them twice. At T1, they performed a neutral Stroop task and a neutral binding task. At T2 (one to three weeks later), after a script-driven dissociative induction, they performed an emotional Stroop task and an emotional binding task. Between the two sessions, they completed questionnaires at home evaluating PTSD severity, trait dissociation and cognitive difficulties. State dissociation was assessed at T1 and T2 using the Clinician-Administered Dissociative States Scale (CADSS). We found good psychometric properties of the French version of the CADSS. After inducing dissociation, significantly lower attentional performance was found among patients with than without dissociative reactions. We found a significant positive correlation between state dissociation and increased attention and memory difficulties after induction. The French version of the CADSS is a reliable and valid tool to assess state dissociation, which is correlated with attentional difficulties. Attentional training is recommended to help patients control dissociative symptoms. [ABSTRACT FROM AUTHOR]

Introduction: Psychotherapy has proved its efficacy for treating a wide range of psychological disorders. Most types of psychotherapy have been developed to treat specific disorders and validated through controlled-randomized trials. In recent years, researchers have developed a new way to conceptualize patients' difficulties, focusing on processes instead of diagnoses. However, there is no simple scale that evaluates transdiagnostic processes, and the development of such a tool is thus the aim of this study., Method: We identified 12 processes that can be targeted in cognitive behavior therapy and created the Transdiagnostic Skills Scale (T2S) to evaluate them. We measured its internal consistency, factor structure and convergent validity in clinical and non-clinical samples., Results: We found a 6-factor structure composed of emotion regulation, behavioral activation/planning, emotional identification, assertiveness, problem solving and emotional confrontation. The T2S has high internal consistency (Cronbach's alpha = 0.95). We found negative associations between skills and symptoms of anxiety, depression and eating disorders. We found no association between these processes and symptoms of either alcohol or cannabis use disorder., Conclusions: The T2S is a useful and valid tool to identify the skills that clinicians should work on with their patients. It offers a complementary way to understand patients' difficulties when categorical assessment is complicated.
