Objective: Blended cognitive behavioral therapy (bCBT) combines face-to-face therapy with digital elements, such as digital health apps. This pilot study aimed to explore the effectiveness and safety of a novel bCBT application for treating unipolar depression in adults combined with cognitive behavioral therapy (CBT) compared to CBT alone in routine care. Methods: Patients (N = 82) were randomly assigned to bCBT (n = 42) or CBT (n = 40) over 12 weeks. bCBT consisted of weekly CBT sessions accompanied by the elona therapy depression module (a bCBT application for unipolar depression) for use between sessions. Standard CBT consisted of weekly CBT sessions. Outcomes (6,12 weeks) were analyzed with linear mixed models. Results: Improvements in depressive symptoms (BDI-II, PHQ-9) were descriptively larger for the bCBT group. Yet, this difference did not reach statistical significance. bCBT was superior to standard CBT in secondary outcome measures of psychological health (d =.50) and generalized anxiety symptoms (d = -.45). In other secondary outcomes (BAI, PSWQ, GSE, WHOQOL-BREF), improvements were descriptively larger for bCBT compared to CBT. Conclusion: This pilot study provided preliminary evidence that bCBT might be advantageous in comparison to CBT alone in the treatment of depression, but larger RCTs of the bCBT application are needed.

Stigmatizing attitudes toward persons with personality disorders are common. Preliminary evidence suggests that continuum beliefs (the view that presented symptoms lie on a continuum with normality) are associated with reduced personality disorder stigma. This study aimed to evaluate whether this association holds across the entire spectrum of personality disorder severity and whether greater personality disorder severity is linked to higher stigma. A general population sample (N = 848) completed questions about a vignette depicting mild, moderate, or severe personality disorder severity. Higher continuum beliefs were associated with a lower desire for social distance from persons with mild, moderate, or severe personality disorder. In addition, continuum beliefs were higher, and the desired social distance was lower toward a person with mild than a person with moderate or severe personality disorder. Thus, fostering continuum beliefs might aid in combating personality disorder stigma, including toward severely affected persons who experience strong stigmatization. [ABSTRACT FROM AUTHOR]

Summary: Nightmares are a substantial burden for sleep quality. Previous studies have shown that traumatic experiences can increase the probability of nightmares, and also waking‐life distress can enhance this effect. There is evidence that the intensity of negative dream emotions is more responsible for rating a dream as a nightmare than threatening dream contents. However, there is still a lack of research concerning effects on nightmare distress. We hypothesise that traumatic childhood experiences (such as emotional abuse, obtained by the Childhood Trauma Questionnaire), critical life events (obtained by the Social Readjustment Rating Scale) and threatening dream contents are associated with nightmare distress. A sample of N = 103 participants kept a dream diary over 28 consecutive days. About 60% of the sample were frequent nightmare dreamers. The participants recorded their violent dream contents and dream emotions in their diary. To predict nightmare distress, regression models were constructed; nightmare distress was measured with the Nightmare Distress Questionnaire. Results showed that emotional abuse in childhood and critical life events predicted nightmare distress. Moreover, violent dream contents were associated with nightmare distress but, after we controlled for nightmare frequency and the intensity of negative dream emotions, the significant impact of violent dream contents decreased. The results suggest that the emotional appraisal of a dream has a substantial influence on nightmares in addition to traumatic childhood experiences and critical life events. [ABSTRACT FROM AUTHOR]

Study Objectives: Perfectionism is considered a predisposing and maintaining factor for insomnia disorder. However, previous studies were predominantly based on retrospective self-reports of sleep and have yielded mixed results. Here, we investigated associations between perfectionism, daily stress levels, pre-sleep arousal, and actigraphic and sleep diary-derived sleep in insomnia using an experience sampling design., Methods: Individuals with insomnia (n = 63) reported their trait perfectionism levels and completed assessments on seven consecutive days. Momentary stress levels were reported on mobile phones at three semirandom time points each day. Presleep arousal levels were rated each morning for the previous night. Sleep onset latency, total sleep time, wake after sleep onset, and sleep efficiency were assessed prospectively using actigraphic watches and sleep diaries., Results: Perfectionism dimensions and daily stress levels did not predict self-reported or actigraphic sleep parameters. Higher levels of somatic and cognitive presleep arousal were robustly associated with indicators of poorer same-night sleep. The concern over mistakes and doubts dimension of perfectionism interacted with cognitive presleep arousal in predicting self-reported sleep parameters. In the presence of higher presleep arousal, participants with high concern over mistakes and doubts experienced shorter self-reported total sleep time and lower sleep efficiency (both P s < .01) than on days with lower cognitive arousal., Conclusions: Taken together, our results did not indicate an impact of heightened perfectionism levels on sleep in individuals with insomnia, based on prospective sleep assessments. However, our findings provide further evidence for the role of somatic and cognitive presleep arousal, potentially interacting with perfectionism, in the perpetuation of insomnia symptoms., Citation: Küskens A, Stricker J, Hertrampf LS, Pietrowsky R, Gieselmann A.
