TLDR
This article explored the relationship between daytime affect and REM sleep in 45 depressed men before and after treatment with cognitive-behavioral therapy and in a control group of healthy subjects to suggest a relationship between phasic REM sleep and intensity of affect reported by depressed men.Abstract:
This article explored the relationship between daytime affect and REM sleep in 45 depressed men before and after treatment with cognitive-behavioral therapy and in a control group of 43 healthy subjects. The intensity of daytime affect (as measured by the sum of positive and negative affects) in depressed men correlated significantly and positively with phasic REM sleep measures at both pre- and posttreatment. This relationship was not found in healthy control subjects. In depressed men, both affect intensity and phasic REM sleep measures decreased over the course of treatment. The results suggest a relationship between phasic REM sleep and intensity of affect reported by depressed men. On the basis of this preliminary observation, it was hypothesized that abnormalities in phasic REM sleep in depressed patients are related, in part, to fundamental alterations in the intensity of their affective experience.read more

TL;DR: A rapid eye movement (REM) sleep hypothesis of emotional-memory processing is proposed, the implications of which may provide brain-based insights into the association between sleep abnormalities and the initiation and maintenance of mood disturbances.

TL;DR: The way sleep impacts next day mood/emotion is thought to be affected particularly via REM-sleep, where a hyperlimbic and hypoactive dorsolateral prefrontal functioning in combination with a normal functioning of the medial prefrontal cortex is observed, probably adaptive in coping with the continuous stream of emotional events the authors experience.

Affect Intensity: Separating Intensity and Frequency in Repeatedly Measured Affect
Ulrich Schimmack,Ed Diener +1 more
TL;DR: In this article, an improved way of differentiating intensity and frequency of affect is proposed that permits one to measure affect intensity separately for each emotion of interest, and the results of three studies using this method provide further support for the affect intensity construct and demonstrate the superiority of the new approach.

A rating scale for depression
TL;DR: The present scale has been devised for use only on patients already diagnosed as suffering from affective disorder of depressive type, used for quantifying the results of an interview, and its value depends entirely on the skill of the interviewer in eliciting the necessary information.
