- Eating disorders and non-suicidal self-injury : cluster analysis considering eating pathology, emotion dysregulation, and negative urgencyPublication . Gonçalves, Sónia; Ramalho, Sofia; Machado, Bárbara C.; Vieira, Ana IsabelAbstract: Research on the interplay between eating pathology, emotion dysregulation and negative urgency is needed to inform intervention approaches for patients with eating disorders and non-suicidal self-injury. This study aimed to investigate the characterization of patients with eating disorders and non-suicidal self-injury considering eating pathology, emotion dysregulation and negative urgency. This cross-sectional study evaluated 73 outpatients with eating disorders and non-suicidal self-injury (14-55 years; 68 women). A cluster analysis was performed using eating pathology, emotion dysregulation and negative urgency. Differences between clusters were explored on sociodemographic/ psychological variables, eating disorder diagnostics and past/current non-suicidal self-injury engagement. Three clusters were identified. Cluster 1 (n=29) (moderate severity) was characterized by high levels of eating pathology, but moderate emotion dysregulation and negative urgency. Cluster 2 (n=29) (high severity) was characterized by the highest scores in eating pathology, emotion dysregulation and negative urgency, and included more patients with current non-suicidal self-injury. Cluster 3 (n=15) (low severity) was characterized by the lowest levels of eating pathology, emotion dysregulation and negative urgency, and included more patients with past non-suicidal self-injury. These profiles highlight the importance of emotion dysregulation and negative urgency as treatment targets for eating disorders patients with current non-suicidal self-injury.
- Depressive symptoms and self-criticism : the mediating role of self-regulation and the moderating role of non-suicidal self-injuryPublication . Gonçalves, Sónia; Moreira, C. S.; Machado, B. C.; Fernandes, Susana; Silva, JéssicaAbstract: Introduction: Non-suicidal self-injury (NSSI) is common among college students and is best understood as a self-soothing method for dealing with aversive emotional states. Aims: To analyse the pathway that sustains the association between NSSI, depressive symptomatology, emotion dysregulation and self-criticism in college students. Method: Three hundred eighty-five students (85.2% females) between 18 and 35 years old (M=20.71;SD=2.80) were evaluated. Results: In the non-NSSI and past-NSSI groups, higher depression increases self-criticism without impairing emotional regulation, a result that was not observed in the current-NSSI group. Therefore, emotion regulation mediated the relationship between depression and self-criticism, but only for the participants with current NSSI. Discussion: NSSI constitute a public health problem during college years. Overall, depressive symptomatology, emotional dysregulation, and self-criticism seem to contribute to a risk profile for the presence and maintenance of NSSI, thus being important for prevention, identification, and clinical intervention on university campuses.
