“…Another drawback related to traditional assessments of PTSD symptoms is incomplete ecological validity – especially as intrusive memories are highly contextual. To overcome these drawbacks and to provide stronger ecological validity, there is a shift towards using ambulatory assessment (AA) during the usual life of the patient both for the assessment of psychopathology in general (FDA, 2009; Trull & Ebner-Priemer, 2013) and for the assessment of PTSD symptoms in particular (Chun, 2016; Walz, Nauta, & Aan Het Rot, 2014). Currently, the two major assessment strategies when using AA are (1) Time-Based Sampling (TBS), in which participants respond to signals emitted by the device; and (2) Event-Based Sampling (EBS), in which participants initiate a diary entry when a pre-specified event occurs (Fahrenberg, Myrtek, Pawlik, & Perrez, 2007).…”

Background: Ambulatory assessment (AA) is increasingly recommended for assessing symptoms of posttraumatic stress disorder (PTSD). Previous AA studies provided new insights into the phenomenology of trauma-related memories, but also divergent findings. Notably, the range of trauma-related memories (a major target of psychotherapeutic interventions) reported in AA studies was as wide as 7.3 to 74.5 per week which might result from different methods used in these studies. Objective: We aimed at assessing the frequency of trauma-related memories in PTSD related to interpersonal violence and investigated whether this frequency is dependent upon the method. Method: For each patient trauma-related memories were assessed using two variants of smartphone-based AA: (1) Event-based sampling (EBS), i.e. participants entered data on each intrusive memory as it occurred; (2) Time-based sampling (TBS), i.e. participants reported the number of trauma-related memories they had experienced during the last two hours after they had been alerted by the smartphone. The numbers reported during the TBS-block were either analysed as reported by the participants or restricted to one per hour (rTBS). The impact of smartphone-assessments on trauma-related memories was assessed during a post-monitoring questionnaire. Results: While trauma-related memories were frequent across assessments, the methodology had a huge impact on the numbers: EBS (median = 7) and rTBS (median = 6) yielded significantly lower weekly numbers of intrusive trauma-related memories than TBS (median = 49). Accordingly, the possibility to report unrestricted numbers of trauma-related memories clearly impacted the results. The post-monitoring questionnaire identified another source for the divergent findings: while feeling disrupted by the smartphone-assessments was unrelated to the numbers reported during EBS, feeling disrupted was related to an increase of trauma-related memories during TBS and rTBS. Conclusions: The method clearly impacts the recorded number of trauma-related memories. Future research should clarify whether other variables (e.g. the subjective stress related to intrusive memories) are less dependent on the methodology.

“…Advantages associated with real-time (or near real-time) methods of assessing alcohol consumption behaviour for research purposes have been widely documented in recent years [1][2][3]. Such methods -which are increasingly electronic in nature -are advocated on the basis they allow data to be captured repeatedly, in the natural environment, and in the absence of the researcher [2,3].…”

“…Real-time methods additionally reduce the quantity of missing data and can yield a diverse and potentially very large sample [4,5]. Crucially, real-time data enables variations in behaviour to be examined across time and in concert with cognitive, affective, environmental, and/or physiological factors; in this way, the antecedents and consequences of drinking behaviour can also be investigated [2,3].…”

“…To prevent recall biases, realtime reports of symptoms by so-called 'ambulatory assessment (AA) methods' have been proposed to prospectively capture the dynamics of symptoms in chronic mental disorders (Trull & Ebner-Priemer, 2013). In the long run, their application is therefore considered worthwhile in predicting recurrent symptoms and preventing full-blown episodes.…”

This Section of Epidemiology and Psychiatric Sciences regularly appears in each issue of the Journal to stress the relevance of epidemiology for behavioural neurosciences, reporting the results of studies that explore the use of an epidemiological approach for providing a better understanding of the neural basis of major psychiatric disorders and, in turn, the utilisation of the behavioural neurosciences for promoting innovative epidemiological research.The final scope is to help the translation of most relevant research findings into every-day clinical practice. These contributions are written in house by the journal's editorial team or commissioned by the Section Editor (no more than 1000 words, short unstructured abstract, 4 key-words, one Table or Although we have gained enormous insights into neurobiological and psychological underpinnings of bipolar disorder (BD) symptoms, our knowledge concerning pathogenic mechanisms initiating recurrent affective episodes is still fragmentary. Previous research has highlighted the role of significant life events and social rhythm in recurrent episodes of mania and depression. However, most studies share the drawback of retrospective self-report data, which are prone to recall biases and limited introspective abilities. Therefore, more objective data, such as neuropsychological and neurobiological measures are needed to further unravel the pathogenic mechanisms of the dynamics of bipolar disorder. Previous research has highlighted disturbed emotional reactivity as well as impaired emotion regulation and impulse control as major behavioural characteristics of BD and aberrancies in prefrontal-limbic-striatal networks that have been proposed to be the correlates of these behavioural alterations. However, longitudinal studies assessing these neural and behavioural alterations are rare. Future research should therefore adopt prospective study designs including behavioural and neuroimaging measures underlying cognitive, emotional and motivational deficits in bipolar disorder. Particularly, these measures should be collected continuously at multiple time points as implemented in modern ambulatory assessment tools. Bipolar disorder (BD) is a highly severe and chronic mental condition with a lifetime prevalence of 2-4% for its most common subtypes (i.e., type I/II). Given the chronic and episodic course of the disease the prediction of recurrent manic and depressive episodes is a major, though not adequately resolved clinical and research question. On a phenomenological level the disease is characterised by phases of (hypo)mania, a state of elevated mood, increased energy, risk-taking and reduced sleep and phases of depression, best described by feelings of sadness, hopelessness, loss of energy and reduced sensitivity to positive outcomes. It has been proposed that increased emotional reactivity, deficient emotion regulation and impulse control as well as motivational dysregulation are important * Address for correspondence: M.
