Frequency of intrusions and flashbacks in patients with posttraumatic stress disorder related to childhood sexual abuse: an electronic diary study.

Intrusions and flashbacks are core features of posttraumatic stress disorder (PTSD). The frequency of these symptoms is usually assessed through retrospective questionnaires, which may be subject to recall bias of unknown magnitude. Electronic diaries that enable real-time assessment have been used to address recall biases in several psychiatric disorders.

Dream recall and nightmare frequency: a family study.

The present study investigated dream recall as well as nightmare frequency in families. Whereas a positive correlation for nightmare frequencies between children and mothers was found (but not for children and their fathers), the relationship for dream recall frequency was small and nonsignificant. Assuming that mothers are still the primary caregivers in the modern family, and, thus, might encourage or discourage children to talk about their dreams, the findings of the study support Cohen's 1973 hypothesis of a socialization effect on nightmare frequency and maybe a smaller effect on dream recall frequency.
