Positive affect inertia uniquely differentiates formerly depressed individuals from healthy controls
Previous studies have shown that emotional dynamics, that is, moment to moment variability and inertia of emotional states, are related to depression, but have no significant contribution after their overlap with mean affect is taken into account. However, few studies considered clinical samples. In our study, we compared a sample of euthymic formerly depressed persons ( n = 94) at high risk of depression recurrence and healthy controls with no h…
Safety Threats of Seasonal and Non‐Seasonal Natural Disasters Increase Disaster Anxiety and Disaster Risk Perception
Living under the threat of natural disasters affects mental health. Natural disasters that are more likely to occur in a specific season represent a special case that is becoming more frequent with the consequences of climate change. Therefore, they deserve special attention regarding their potentially seasonal mental health implications. We investigated seasonal and non‐seasonal natural disasters and levels of exposure in terms of threatened saf…
Can Self‐Reported Seasonality Predict Prospectively Assessed Seasonal Changes of Self‐Reported Mood, Food Cravings, Body Weight, Insomnia, and Physical Activity
Controversy about seasonal affective disorder lies in the poor match between its definition and the available screening methods, as well as little knowledge about the predictive value of specific seasonal symptoms assessed by those methods. We examined whether the overall score as well as sub‐domains of the seasonal pattern assessment questionnaire can predict seasonal changes in mood, sleep, appetite, weight, and physical activity in a one‐year …
EEG-responses to mood induction interact with seasonality and age
The EEG is suggested as a potential diagnostic and prognostic biomarker for seasonal affective disorder (SAD). As a pre-clinical form of SAD, seasonality is operationalized as seasonal variation in mood, appetite, weight, sleep, energy, and socializing. Importantly, both EEG biomarkers and seasonality interact with age. Inducing sad mood to assess cognitive vulnerability was suggested to improve the predictive value of summer assessments for wint…
Predictability of Seasonal Mood Fluctuations Based on Self-Report Questionnaires and EEG Biomarkers in a Non-clinical Sample
Induced by decreasing light, people affected by seasonal mood fluctuations may suffer from low energy, have low interest in activities, experience changes in weight, insomnia, difficulties in concentration, depression, and suicidal thoughts. Few studies have been conducted in search for biological predictors of seasonal mood fluctuations in the brain, such as EEG oscillations. A sample of 64 participants was examined with questionnaires and elect…
