... between (1) subjective sleep and ESM measures of affect the next day, and between (2) ESM daytime affect and subsequent sleep, were separately calculated using the XTMIXED command in STATA (version 11 for Windows) (see Figure 1). The first model included sleep as a predictor of affect the next day and was additionally corrected for food and alcoholic intake, physical exercise and age. ...

For the duration of 5 consecutive days, par- ticipants rated positive and negative affect items ten times a day and filled in sleep questionnaires in the morning and evening. ...

... 95% CI [-.055, -.001]) indicating that allelic variation moderated the association between sleep quality and positive affect. As shown in Figure 1, carriers of one or two S-alleles had a significantly steeper slope compared to LL carriers (χ²=4.16, p=.042 and χ²=3.90, p=.048 respectively). ...

... both laboratory-controlled [3,4] and real-life settings [2][3][4][5][6][7], PA and NA have been demonstrated to differ in the way they dynamically unfold over the day, referred to as diurnal mood variation (DMV). PA shows a quadratic variation ('inverted u-curve') when considering the waking portion (usual daytime) of the 24-hour cycle, with the lowest levels observed during the morning and evening (see Figure 1). When the entire 24-hour cycle is considered (day and night), PA shows a sinusoidal curve, with lowest levels during the late night and highest levels during the day. ...

... report on a first, ongoing study in which depressed patients collect ESM data over a 6-week period and receive weekly verbal and graphical feedback on daily life contexts (social context, current activities, physical activity etc.) in relation to their momentary emotional responses. Also, they receive feedback on changes in relevant emotional and behavioural patterns over time (Figure 1). The aim is to give patients more insight into functional and dysfunctional behaviours in daily life. ...

... total of 309 patients underwent an initial screening by telephone, of which 102 were allocated at random to the experimental, pseudo-experimental or control groups (see Figure 1 for the participant flow through the study). At screening, the groups showed some differences in clinical features: Compared to the pseudo-experimental and con- trol group, patients in the experimental group more often used lithium and displayed lower HDRS scores (Table 1); these differences were no longer significant at baseline (two weeks later, i.e., just before the start of the intervention, see also [19]). ...

... work has shown that ESM assessments with less than 30% of filled out beeps are less reliable and consequently not valid [13]. Therefore, ESM periods (one period corresponding to one ESM 'week' in the protocol) with less than 30% of beeps completed were excluded from the analyses, leading to the exclusion of one baseline ESM period, four post ESM periods, and two periods during the intervention period (Figure 1). ...

... presented in chapter 3, sleep and daily affect regulation are closely associated. This relationship appeared to be not entirely bidirectional, as the associations between affect and previous nights' sleep was stronger than between affect and subsequent sleep (indicated by the varying thickness of arrows in Figure 1). Thus, our findings provide support for the emotion homeostasis model as proposed by Walker [1][2][3]. ...

... integrating the insights of part one ('measuring') and part two ('intervening') of the present thesis, several recommendations can be provided to guide and inform future research. The model of micro-mechanisms potentially underlying depression in part 1 (Figure 1), showed the apparent importance of endogenous rhythms, sleep- wake related processes, and PA, warranting future interventions precisely targeting these processes. Therefore, subsequent interventions should be aimed at stabilizing endogenous rhythms, enhancing sleep quality, and enhancing the experience of positive affect. ...
