Background Lifetime traumatic events are prevalent in women with Premenstrual Dysphoric Disorder (PMDD) and predict stronger premenstrual symptom intensities. Less is known about the unique effects of childhood adversity on PMDD. This study aims to investigate the menstrual cycle related course of mood, stress appraisal and cortisol activity over t...

Premenstrual dysphoric disorder (PMDD) is characterized by a cyclical symptom course. Previous research provides limited findings on possible menstrual-cycle-related psychological and psychoendocrinological processes in PMDD. By using ambulatory assessment (AA), we aimed to compare mood and cortisol cyclicity in individuals with PMDD and healthy co...

Background The psychological risk factors of premenstrual dysphoric disorder (PMDD) are not fully understood, but initial evidence points to a potential role of unfavorable cognitive emotion regulation (ER-) strategies. Given the symptom cyclicity of PMDD, ambulatory assessment is ideally suited to capture psychological and physiological processes...

Background Core Premenstrual Disorders (PMDs), including Premenstrual Syndrome (PMS) and Premenstrual Dysphoric Disorder, can cause significant impairment. Despite evidence linking stress and premenstrual symptoms, a systematic synthesis is lacking.AimsTo systematically review the literature and meta-analyse evidence on the relationship between pre...

Premenstrual dysphoric disorder (PMDD) is characterized by pronounced affective core symptoms as well as other psychological and physical symptoms that occur in the luteal phase, usually in the premenstrual week and subside after the onset of menstruation. The PMDD has been included in the International Classification of Diseases 11 (ICD-11) in the...

Background Core Premenstrual Disorders (PMDs), including Premenstrual Syndrome and Premenstrual Dysphoric Disorder, can cause significant impairment. Despite evidence of associations between stress and premenstrual symptoms, a systematic synthesis is lacking.AimsTo systematically review the literature and meta-analyse evidence on the relationship b...

In Major Depressive Disorder, first evidence shows heightened mood-reactivity toward daily events. Related longitudinal studies in remitted patients with recurrent major depression are lacking. Long-term changes in such short-term within-person associations can be analysed via measurement burst designs. Two bursts, separated by approximately 4.4 ye...

Objective: To present the design, development, and pilot testing of Connections, an empirically derived cooperative card game intervention to reduce loneliness and enhance connection. Materials and Methods: Theory and empirical evidence from domains such as self-disclosure, interpersonal closeness, and serious games informed the design of this game...

Rumination has been proposed as an important risk factor for depression, whereas mindful attention is considered a protective form of self-focusing. Experimental studies have demonstrated differential effects of these modes when induced in the lab. However, their impact on daily life processes is poorly understood, particularly in individuals vulne...

Habitual modes of thinking such as repetitive negative thinking (RNT), but also momentary cognitive processes such as mindwandering could be vulnerability factors for the course of Major Depressive Disorder (MDD). On the physiological level, cortisol represents an important biological stress marker of the hypothalamic-pituitary-adrenal (HPA) axis....

Subthreshold premenstrual symptoms can be impairing even if the diagnostic criteria for premenstrual dysphoric disorder (PMDD) are not reached. Previous research suggests shared psychological risk factors without a clear differentiation of premenstrual syndrome (PMS) from PMDD. This study focuses on a sample with a wide range of premenstrual sympto...

Major Depressive Disorder is a recurrent condition. Potential risk factors for future episodes are maladaptive cognitions such as rumination and unfavorable reactivity toward negative daily events. Positive thoughts and positive daily events, in contrast, could act as a buffer against mood deterioration. The aim of the present study is (1) to exami...

Purpose of Review In contrast to premenstrual dysphoric disorder (PMDD), premenstrual exacerbations (PMEs) of ongoing mood disorders are understudied. The aim of this review is to describe diagnostic issues, epidemiology, underlying mechanisms, and treatment for PME in unipolar depression and bipolar disorder, and to discuss clinical and research i...

Data from 213 adults were analysed to test the stress accumulation and stress sensitization models as they relate to daily mood, health behaviours and social interactions. Adults reported on childhood adversity, past year adversity, and daily experiences on 14 evenings. Results largely supported the stress accumulation and not stress sensitization...

Background It is unclear how adverse childhood family environments differentially impact adult health outcomes among men and women. This brief communication reports on the independent and joint effects of adverse childhood family environments and sex on indicators of health in adulthood. Methods & Results 213 18-55-year olds reported on their chil...
