Universal prevention for non-suicidal self-injury in adolescents is scarce - A systematic review
(2023)
Non-suicidal self-injury (NSSI) during adolescence is a high-risk marker for the development and persistence of mental health problems and has been recognized as a significant public health problem. Whereas targeted prevention has indeed shown to be effective in reducing NSSI and improve mental health problems, access to such programs is limited. By face validity, universal prevention of NSSI seems an ideal starting point for a stepped-care model to circumvent a lack of resources in the medical care system. However, it is yet unclear how effective such approaches are. Here, we provide a summary of existing work on universal prevention of NSSI in adolescents younger than 21 years based on a systematic literature search. We found that only seven studies are available. None of the programs evaluated was found to be effective in reducing the incidence or frequency of NSSI. After providing a comprehensive summary of the existing work, we evaluate the fact that existing work primarily focusses on selected/targeted prevention and on psychoeducational methods. We derive implications for future directions in the field of universal prevention of NSSI.
Vorherige Studien beschreiben bei der Aufmerksamkeitslenkung präfrontale Aktivierungen im rechten DLPFC und DMPFC. Diese Studie wollte untersuchen, ob die Aufmerksamkeitslenkung durch Richten des Fokus auf nicht -emotionale Bildinhalte innerhalb eines Stimulus zu präfrontalen Effekten führt. Dazu wurde eine kombinierte Messung aus EEG, fNIRS und emotionalem Arousal erhoben. Die Bedingungen beinhalteten entweder das passive Bildbetrachten oder die Aufmerksamkeitslenkung. Das EEG wurde als Kontrollbedingung erhoben, um zu replizieren, dass die Aufmerksamkeitslenkung auf nicht –emotionale Bildinhalte zu einer Reduktion des LPP und des emotionalen Arousals führt. In dieser Studie konnte sowohl ein reduziertes LPP als ein geringeres emotionales Arousal bei der Aufmerksamkeitslenkung beschrieben werden. In der fNIRS zeigten sich jedoch weder ein signifikanter Emotions- noch ein signifikanter Regulationseffekt, sodass keine Aktivierungen präfrontal bei der Aufmerksamkeitslenkung beschrieben werden konnte. Es sind somit weiterführende Studien zur Aufmerksamkeitslenkung notwendig, ob die Aufmerksamkeitslenkung zu präfrontalen Aktivierungen führt, und ob diese mit der fNIRS abgebildet werden können.
Regulating our immediate feelings, needs, and urges is a task that we are faced with every day in our lives. The effective regulation of our emotions enables us to adapt to society, to deal with our environment, and to achieve long‐term goals. Deficient emotion regulation, in contrast, is a common characteristic of many psychiatric and neurological conditions. Particularly anxiety disorders and subclinical states of increased anxiety are characterized by a range of behavioral, autonomic, and neural alterations impeding the efficient down‐regulation of acute fear. Established fear network models propose a downstream prefrontal‐amygdala circuit for the control of fear reactions but recent research has shown that there are a range of factors acting on this network. The specific prefrontal cortical networks involved in effective regulation and potential mediators and modulators are still a subject of ongoing research in both the animal and human model. The present research focused on the particular role of different prefrontal cortical regions during the processing of fear‐relevant stimuli in healthy subjects. It is based on four studies, three of them investigating a different potential modulator of prefrontal top‐down function and one directly challenging prefrontal regulatory processes. Summarizing the results of all four studies, it was shown that prefrontal functioning is linked to individual differences in state anxiety, autonomic flexibility, and genetic predisposition. The T risk allele of the neuropeptide S receptor gene, a recently suggested candidate gene for pathologically elevated anxiety, for instance, was associated with decreased prefrontal cortex activation to particularly fear‐relevant stimuli. Furthermore, the way of processing has been found to crucially determine if regulatory processes are engaged at all and it was shown that anxious individuals display generally reduced prefrontal activation but may engage in regulatory processes earlier than non‐anxious subjects. However, active manipulation of prefrontal functioning in healthy subjects did not lead to the typical behavioral and neural patterns observed in anxiety disorder patients suggesting that other subcortical or prefrontal structures can compensate for an activation loss in one specific region. Taken together, the current studies support prevailing theories of the central role of the prefrontal cortex for regulatory processes in response to fear‐eliciting stimuli but point out that there are a range of both individual differences and peculiarities in experimental design that impact on or may even mask potential effects in neuroimaging research on fear regulation.
