A sustainable, low-cost medium based on food waste for cultivating the cyanobacterium Arthrospira platensis (A. platensis) was investigated. Zarrouk medium components, especially phosphate, were substituted with extracts from beetroot peel, brewer’s grains, and walnut press cake. Ion concentrations of magnesium, calcium, iron, potassium, sodium, phos-phate, nitrate, sulfate, and chloride were analyzed to determine the optimal medium composition. Walnut press cake and brewer’s grains extracts showed high potential due to their magnesium, calcium, and phosphate content. Brewer’s grains extracts also provided glucose as an additional carbon source. Cultivations in shaking flasks and a photobioreactor (PBR) monitored cell growth through optical density and biomass concentration. The excess of magnesium and reduced phos-phate concentrations positively affected biomass production. A. platensis’s ability to metabolize glucose resulted in 68% higher biomass production. Growth in brewer’s grains extract required no additional phosphate. PBR cultivation showed A. platensis consumed significant magnesium and nitrate, achieving higher biomass concentrations with optimized gas exchange and light reflection systems.

Abstract Background A valid, quick and widely applicable retrospective screening tool for child maltreatment is of great importance to better adapt interventions and treatments. The Childhood Trauma Screener (CTS), derived from the Childhood Trauma Questionnaire (CTQ), is one such instrument that aims to increase the likelihood of detecting mental and physical disorders that have manifested in adulthood as a result of traumatic experiences and maltreatment in childhood and adolescence. The present study aimed to investigate the psychometric properties of the CTS and generate normative data. Methods Data from two representative surveys were combined. Both surveys used identical methods. The CTS, consisting of five items, other self-report instruments, and demographic characteristics were used. Construct validity was examined using confirmatory factor analysis (CFA). A subsample was used to examine convergent validity with the Adverse Childhood Experiences Questionnaire (ACE). Normative data are reported for age groups and gender. Results A total of 5039 study participants provided valid responses to the 5-items questionnaire (54.3% female, response rate = 78.9%). CFA showed good fit indices for a 2-factor solution. Convergent validity was generally supported by moderate intercorrelations with the ACE. Conclusions The results confirm the solid psychometric properties of the CTS as an easy-to-use, ultra-short retrospective measure of child maltreatment. The data can be used to compare sample or individual results with reference data provided.

Introduction: The number of reportings on sexual abuse (SA), sexual violence (SV) cases covered in the media has risen a significant amount with most cases involving women and children. The aim of the study is to explore the questions: Are people aware of sexual abuse and sexual violence in the media? What are the predictors of awareness of sexual abuse and sexual violence? Does the awareness of sexual abuse and sexual violence in the media affect the actions of the individuals?Methods: A representative survey of the German-speaking resident population (2020) on physical and mental well-being was used. The participants (N = 2,503: females = 50.9%) were between the ages of 14 and 97 (M = 49.81). The German version of the Adverse Childhood Experiences Questionnaire, The General Habitual Well-Being Questionnaire and questions about own experiences of sexual harassment on the internet, experiences of domestic sexual abuse and different socio-economic variables were used. The outcome variables regarding the awareness of SA and SV in the media, different types of scandals (church, pedophile, USA), #MeToo-debate and the change in actions were used. Frequency analyses and binary regressions were conducted.Results: One thousand five hundred and fifty-five (62.6%) respondents answered yes to being aware of SA and SV in the media. The results show that females, aging, number of children in household, Protestant and Catholic religion, school graduation, own experience(s) of sexual harassment on the internet, own experience(s) of SA in childhood, and Adverse Childhood Experiences have a significant higher association to the awareness of SA and SV in the media. German nationality and Muslim religion have a significant lower association. The variables that most commonly affected the awareness of SA and SV, scandals, debate and the individual actions were age, own experiences of sexual harassment on the internet and the Protestant religion.Conclusion: Advertising more support centers, hotlines and linking this information to sexual abuse cases covered in the media should be considered. Media bystander interventions could be helpful to train people to react appropriately. Further investigation that considers the different types of media and its influence on the awareness of SA and SV is needed.

Abstract Background Child maltreatment is an identified risk factor for Non-Suicidal Self-Injury (NSSI). The aim of the current study was to investigate effects of different types of maltreatment, and mediating effects of depression and anxiety on NSSI in the general population. Methods A representative sample of the German population, comprising N = 2498 participants (mean age = 48.4 years (SD = 18.2), 53.3% female) participated in this study. Child maltreatment was assessed using the Childhood Trauma Questionnaire (CTQ),NSSI was assessed with a question on lifetime engagement in NSSI, depressive symptoms were assessed by the Patient Health Questionnaire (PHQ-2) and anxiety symptoms by the General Anxiety Disorder questionnaire (GAD-2). Results Lifetime prevalence of NSSI in this sample was 3.3, and 30.8% reported at least one type of child maltreatment. Participants in the NSSI group reported significantly more experiences of child maltreatment. Emotional abuse was endorsed by 72% of all participants with NSSI. A path analytic model demonstrated an unmediated direct effect of emotional neglect, a partially mediated effect of emotional abuse, and a fully mediated effect of sexual abuse and physical neglect by depression and anxiety on NSSI. Conclusions Especially emotional neglect and abuse seem to play a role in the etiology of NSSI above and beyond depression and anxiety, while sexual and physical abuse seem to have a rather indirect effect.

Abstract Background Child maltreatment of all types is a serious concern for society, and it is important to monitor trends in incidence in order to inform child welfare agencies and policy-makers about emerging issues. In Germany, however, information on such trends is limited: apart from official sources, the only published study is a comparison of surveys conducted in 1992 and 2011 that had focused primarily on sexual abuse. The present study is the first to look at more recent trends and to examine other types of maltreatment as well. Methods We compared the datasets of two population-based nationwide surveys, one conducted in 2010 (N = 2504) and the other in 2016 (N = 2510). Both had used identical methodology. Participants aged 14 years and older had been selected randomly using the Kish selection grid method, and information about childhood experiences of abuse had been solicited using the Childhood Trauma Questionnaire. Results The overall percentage of respondents who reported having experienced at least one type of child maltreatment decreased over the 6 years, from 35.3% in 2010 to 31.0% in 2016; however, the percentages who reported multiple types of maltreatment remained stable. The decrease in any type of maltreatment was mainly driven by fewer reports of physical neglect, which was likelier to be reported by older respondents who had experienced privation during the (post-) war years and whose representation was lower in the later survey. There was a significant increase over time in the prevalence of emotional abuse, with respondents aged 26–45 years reporting higher rates of this type of maltreatment. The prevalence rates of other types of maltreatment remained unchanged. All effect sizes were very small. Conclusions At present, the systems in place in Germany for monitoring the occurrence of child maltreatment are insufficient. While this study contributes to a better understanding, more information is needed, particularly on populations that have been excluded or underrepresented in previous research efforts. As has been done elsewhere, large databases should be set up, using identical methodologies and definitions, in order to accurately assess trends over time in different types of abuse and neglect.

Abstract Background Child maltreatment and its consequences are considered a major public health problem. So far, there is only one study from Germany reporting prevalence rates on different types of maltreatment. Methods A representative sample of the German general population was examined for experiences of child maltreatment using the Childhood Trauma Questionnaire (CTQ) between September and November 2016. A total of 2510 (53.3% female) participants between 14 and 94 years (M = 48.8 years) were enrolled. Besides the CTQ, a range of sociodemographic information was collected. The interrelatedness of different types of maltreatment was examined using configuration analysis and predictors for maltreatment were identified by performing binary logistic regression analyses. Results Overall, 2.6% (f: 3.9%, m: 1.2%) of all participants reported severe emotional abuse, 3.3% (f: 3.4%, m: 3.3%) severe physical abuse, 2.3% (f: 3.7%, m: 0.7%) severe sexual abuse, 7.1% (f: 8.1%, m: 5.9%) severe emotional neglect and 9% (f: 9.2%, m: 8.9%) severe physical neglect. Women were more likely to report at least moderate sexual and emotional abuse than men. The largest difference between age groups was reported for physical neglect, with participants aged over 70 years reporting the highest rates. Participants who reported childhood maltreatment were more likely to be unemployed or have lower educational outcomes. The most common combination of maltreatment types were physical and emotional neglect, all five types of maltreatment combined and physical and emotional neglect and physical abuse combined. Conclusions Child maltreatment, especially physical neglect is common in the German population. Women seem to be at greater risk for sexual and emotional abuse than men. Knowledge about different types of maltreatment based on the Childhood Trauma Questionnaire (CTQ) can help to put findings of future studies into an epidemiological and societal context.

Abstract Background Dysfunctional trauma-related cognitions correlate highly with chronic stress. Studies on maltreatment-related cognitions and their predictors in children and adolescents are rare. Methods The study sample consisted of 231 children aged 8–17 years who had experienced maltreatment including domestic violence, emotional abuse, neglect, physical, and sexual abuse. Using multiple linear regression analysis, gender, age, index-event, multi-type maltreatment, out-of-home-care, and migration background were investigated as possible predictors of dysfunctional maltreatment-related cognitions. Additionally, the associations between dysfunctional cognitions and posttraumatic stress symptoms (PTSS) as well as further internalizing and externalizing symptoms were calculated. Results Gender emerged as a significant predictor of dysfunctional maltreatment-related cognitions. Moreover, there was an interaction effect of gender and age, with female adolescents showing most dysfunctional cognitions. Furthermore, experiencing five different maltreatment types had an impact, leading to more dysfunctional cognitions compared to single-type maltreatment. Dysfunctional maltreatment-related cognitions correlated highly with PTSS and internalizing symptoms, and moderately with externalizing symptoms. Conclusions Dysfunctional maltreatment-related cognitions are associated with psychological symptoms after maltreatment and, therefore, need to be addressed in assessment and treatment.

We present data on maltreatment profiles and psychopathology of 358 children and adolescents (4–17 years). Data on maltreatment profiles has been categorized into six major maltreatment types: physical abuse, emotional abuse, sexual abuse, sexual abuse with penetration, exposure to intimate partner violence and neglect. The data on history of maltreatment is based on the interview version of the Juvenile Victimization Questionnaire (JVQ). Additionally data on psychopathology in general as well as specific disorders according to DSM-IV based on K-SADS-PL is presented. The data was used to examine patterns of co-occurrences of maltreatment and associated clinical outcome variables using latent class analysis (LCA), “Experience by children and adolescents of more than one type of maltreatment: association of different classes of maltreatment profiles with clinical outcome variables” (Witt et al.,) [1]. Keywords: Child maltreatment, Latent class analysis, Child abuse and neglect, Psychopathology
