How Observed Personality Traits in (Mildly) Depressed Adolescents Relate to Nonverbal Responses of Peers.

Depression in adolescence is related to negative social responses. Previous studies indicate that negative responses precede, co-occur and follow depressive episodes, indicating that more stable characteristics of depressed(to-be) adolescents may trigger such responses. This study examines whether personality traits, as observed in behavior, mediate or moderate responses of peers towards (mildly) depressed adolescents.

Does Less Optimal Nonverbal Communication with Peers Predict the Development of Depression in Adolescent Boys and Girls?

A Social Skills Deficit Model for depression in adolescence was tested, proposing that less optimal nonverbal behavior elicits negative reactions in peer partners, which in turn result in depressive symptoms. Adolescents (12-17 years of age) participated in videotaped same-sex interactions. Several positive and negative nonverbal behaviors were coded.

Age and gender differences in depression across adolescence: real or 'bias'?

Background: Since developmental psychologists are interested in explaining age and gender differences in depression across adolescence, it is important to investigate to what extent these observed differences can be attributed to measurement bias. Measurement bias may arise when the phenomenology of depression varies with age or gender, i.e.

[Two travellers suffering from typhus].

Background: Endemic typhus, caused by Rickettsia typhi, belongs to the typhus group of the rickettsioses. The disease is prevalent worldwide and is probably an underestimated cause of illness accompanied by fever in travellers, due to its frequently mild presentation and resemblance to diseases like typhoid- or dengue fever. Broad-spectrum antibiotics are not effective in the treatment of endemic typhus, but the disease is responsive to doxycycline.
