Bowlby (1984) regarded attachment as a model of psychological vulnerability to depression. Since then, a large number of studies have considered vulnerability to depression in light of the idea of attachment style. Attachment styles correspond to two dimensions observed in relationships (anxiety and avoidance) evoking ideally the internal operating models of self and other respectively, as first described by Bowlby (1984). Two types of adult attachment styles are evaluated in our study: romantic attachment (Hazan and Shaver, 1987) and interpersonal attachment (Bartholomew and Horowitz, 1991). The existing literature indicates that depression is associated with the insecure attachment styles, in both romantic an interpersonal relationships. Nevertheless, a question remains concerning the nature of the link between attachment style and depression: are attachment styles stable and independent of the depression or are they modified as the depression evolves? The aim of the present study was to investigate the relationships between attachment and depression in adult women hospitalized for depression; following up the evolution in their romantic and interpersonal attachment styles from the beginning to the end of their hospitalization. ⋯ Our results confirm that romantic and interpersonal styles of attachment constitute factors of vulnerability to depression. But more importantly, these findings open up new perspectives in terms of the nature of the relationships between attachment styles and depression. They provide matter for discussion concerning the stability or the change in romantic and interpersonal attachment styles. Indeed, we have revealed the stable and independent nature of romantic attachment styles in relation to depressive symptomatology. On the contrary, security in the interpersonal attachment style was shown to be a factor of change, associated with the evolution of the depressive symptomatology in progress. In the quest to take combined account of romantic and interpersonal attachment styles and their links with the evolution of depression, the present study results in a new understanding of depression, viewed from the perspective of the model of attachment in adults.

The study of children's personality and its development has generated several theoretical models in psychology. In a developmental approach, Buss and Plomin elaborated a genetic model of temperament that involves four dimensions: emotionality (refers to the negative quality of the emotion and the intensity of the emotional reactions), activity (intensity and frequency of a person's energy output in motor movements and speech), sociability (search for social relationships and preference for activities with others) and shyness (behavioural inhibition and feelings of distress when in interaction with strangers). The psychobiological approach postulates a biological model of personality. Thus, in Gray's first model, there are two brain systems that explain behaviours: the Bbehavioural Activation System (BAS) related to impulsivity and the Behavioural Inhibition System (BIS) linked to anxiety. Finally, dispositional theories seek to identify functional units of the normal personality from the factorial approach. Accordingly, Barbaranelli et al. build a questionnaire, the big five questionnaire for children (BFQ-C), which is intended to estimate the emergence of five fundamental dimensions (energy/extraversion, agreeableness, conscientiousness, emotional instability and intellect/openness) in children from 8 to 18 years. The clinical study we will present concerns the personality of children suffering from attention-deficit hyperactivity disorder (ADHD). STUDY 1: ⋯ It is interesting to note that children have a less stable representation of their own temperament as compared to the evaluation of their parents. This study replicates the findings of previous research on adults with ADHD regarding neuroticism (emotional instability), but contrary to findings in adults with ADHD, children obtained elevated scores on the conscientiousness and agreeableness subscales. In accordance with our hypotheses, children with ADHD could be distinguished from control participants on the BAS, particularly for the drive and reward responsiveness subscales. Furthermore, they also obtained higher scores on the extraversion subscale of the BFQ-C and the on the EAS activity subscale.

A positive link between alexithymia and delinquency, as well as a negative link between alexithymia and emotional intelligence, has already been demonstrated. Previous studies have highlighted that emotional intelligence is associated with antisocial behaviour. Even though the frequency of alexithymia has been explored in non-clinical samples of adolescents, the relationship between alexithymia and delinquency has not been studied in community samples of adolescents. Furthermore, the link between alexithymia, emotional intelligence and interpersonal delinquency has never been explored in such a sample. The aim of the current study was to explore the relationship between alexithymia, emotional intelligence and interpersonal delinquency in a sample of high-school students. ⋯ Our findings suggest the importance of taking into account the emotional dimensions in the care of teenagers presenting antisocial behaviours. It appears of prime importance to lead young people presenting antisocial behaviours to identify their feelings.

Personality and its disorders have been the subject of many studies in philosophy, psychology or medicine. Current nosology gives preference to categorical classifications, but a dimensional approach may also be considered. Supported by Cloninger's psychobiological model, it refers to concepts of temperament (novelty seeking, reward dependence, harm avoidance and persistence) and character dimensions (self-directedness, cooperativeness and self-transcendence). Categorical and dimensional approaches do not appear antinomic, and the PerCaDim study tries to verify the hypothesis of correlations existing between them. ⋯ These results confirm previous findings that Cloninger's dimensions can objectify personality disorders. Few dimensions of the Temperament and Character Inventory can be considered as vulnerability factors. The use of the Temperament and Character Inventory will most certainly be of good help in the future to detect or prevent a personality disorder in some subjects at risk.

Repetitive transcranial magnetic stimulation (rTMS) is a brain stimulation technique that has been investigated as a novel treatment for psychiatric disorders, notably in major depression, and has shown statistically significant effects. The authors found it necessary to propose an up-to-date review of positive predictors for antidepressive response to repetitive transcranial magnetic stimulation. ⋯ Parameters of stimulation must be adapted according to the treated patients. For example, older patients who present cortical atrophy need higher intensity of stimulation. Other criteria could influence effectiveness of rTMS in the same way. Would it be necessary, for example, to adapt the duration or the intensity of stimulation according to the severity of the depressive episode or its duration of evolution? Do antecedents of resistance to a pharmacological treatment oblige us to stimulate differently? Few studies exceed 10 days of treatment; will longer duration of treatment be more effective? Also, we did not find any data on the interest of maintenance treatment among responders. Should the characteristics of the depressive disorder or its evolution require maintenance treatment? What will be its rhythm and its duration? Should we adapt rTMS parameters to abnormalities highlighted by functional neuroimagery? The prospects for work remain numerous.
