Theme leader: Monique Pfaltz
Childhood maltreatment (abuse and neglect), or childhood trauma, has long-term effects on mental and physical health. It also negatively impacts social functioning, which, in turn, is closely linked to health and well-being. Projects under this theme explore the cross-cultural underpinnings of childhood maltreatment, examine its influences on lifespan development, and identify culture-specific protective factors that enhance resilience in this vulnerable population. More specifically, we aim to improve the trans-cultural understanding of emotional, cognitive, behavioral, physiological as well as societal factors that underlie mental and physical well-being as well as healthy (e.g. satisfying close relationships) and impaired social functioning (e.g. regarding the updating of social information, the regulation of closeness and distance, or the processing of interpersonal signals like facial expressions) in those affected by childhood maltreatment. Our research shall serve as a basis for the development of interventions that prevent child maltreatment and its negative consequences as well as interventions that improve mental and physical well-being as well as the quality of social relationships in affected individuals.
We are using systematic review and meta-analytic approaches to summarize the current state of knowledge (e.g., regarding the link between childhood maltreatment and somatic symptoms or the intergenerational transmission of maltreatment across cultures), as well as experimental procedures (including peripheral-physiological measures) and online surveys to collect data around the world. We are furthermore working on the development of brief interventions (e.g., culturally adapted videos to reduce self-stigma and improve treatment-seeking behavior in individuals affected by child maltreatment). Our project groups comprise both junior and senior researchers and we are organizing online workshops and outreach activities to support the initiation of new projects and to disseminate knowledge to a diverse audience.

Understanding the link between child maltreatment and somatic symptoms
Contact: Antonia Lüönd (antonia.luondATpukzh.ch), Görkem Ayas (gayas17ATku.edu.tr)
Aim: The term somatic symptoms is used to describe physical complaints (e.g. pain, functional neurological symptoms) for which no physical cause has been found. Prior research has documented links between these somatic symptoms and environmental influences such as childhood maltreatment and social/ cultural factors. This project aims to advance our understanding of the impact of childhood maltreatment on somatic symptoms in adulthood.
Methods: Currently, the project members are working on a systematic review to summarize the current knowledge about the impact of childhood maltreatment on somatic symptoms and to identify gaps in research that could be addressed in a future (clinical) study. After completion of the systematic review, the group aims to approach these gaps by conducting a prospective study.
Current status: The project is in an early phase and new team members are welcome to join.
Cross cultural emotion recognition in traumatized individuals across the life span
Contact: Monique PfaltzMonique Pfaltz (monique.pfaltzATmiun.se), Misari Oe (oe_misariATkurume-u.ac.jp), Ueli Schnyder (ulrich.schnyderATaccess.uzh.ch)
Aim: Individuals exposed to child maltreatment seem to have difficulties to identify other’s emotional facial expressions – an important aspect of social interactions. Yet, previous research relies on experimental emotion recognition paradigms that comprise pictures or videos of Caucasian faces, focusing on populations from the U.S. or Europe. This project aims to understand trauma-related, potentially culture-dependent alterations in the processing of facial expressions, with the long-term goal to develop interventions that improve affected individuals’ social well-being.
Methods: Children and adults with a history of child maltreatment shall be assessed, using experimental (emotion recognition, emotion induction and other) paradigms and psychophysiological approaches (e.g. facial EMG, electrocardiogram, electrodermal activity). Important steps will be to gain an overview of existing experimental paradigms and to adapt these paradigms where necessary.
Current status: Initial results from Switzerland suggest that adults exposed to child maltreatment have difficulties in identifying positive facial expressions and tend to misinterpret neutral facial expressions as negative, whereas facial mimicry (i.e., the automatic imitation of others’ facial expressions) seems to be intact. We started to examine whether these findings extend to adult Japanese individuals and whether child maltreatment affects the intensity of self-reported and physiological responses to video clips inducing negative and positive affect in Swiss and Japanese individuals. Due to Covid-19 related restrictions, the data collection in Japan is on hold.

Reducing self-stigma and increasing treatment-seeking related to child maltreatment
Contact: Shilat Haim-Nachum (Shilat.HaimNachumATnyspi.columbia.edu)
Aim: This project targets reducing self-stigma related to childhood maltreatment (e.g., shame, guilt, secrecy) and increasing openness to seek treatment if needed. We seek to test the effectiveness of this online intervention across different countries.
Methods: Randomized controlled trial, transcultural online-intervention, including culturally adapted selfie video stimuli. The brief video (~2 minutes) shows an actress describing her hardships resulting from childhood maltreatment and how she benefited from psychotherapy, whereas control participants observe a same-length video where the actress describes her daily activities, without any mention of childhood maltreatment.
Current status: The project is in the planning phase. Data collection will start around fall 2023.

The impact of child maltreatment on preferred interpersonal distance
Contact: Monique Pfaltz (monique.pfaltzATmiun.se)
Aim: Previous studies suggest that children and adults with a history of child maltreatment prefer larger interpersonal distances towards strangers, which might affect long-term social well-being.
Method: This aim of this project is to assess whether these initial finidngs finding can be replicated across cultures and whether adults with various levels of child maltreatment also prefer larger distances towards close others. Assessment of preferred interpersonal distance and collection of questionnaire data (i.a., on trauma history) were conducted online, in over 10 languages.
Current status: The data collection has been completed; more than 3600 people have participated. Results are available online (see links/publications) and will soon be published.
Child maltreatment and social updating
Contact: Einat Levy-Gigi (firstname.lastname@example.org)
Aim: This project builds on the above-described CM-IPD project and aims to shed light on the mechanism beyond social avoidance in individuals who experienced child maltreatment. Based on our own and other findings of negative responses to social stimuli (e.g., feeling uncomfortable with physical closeness to strangers) in individuals affected by child maltreatment, we hypothesize that – across cultures – higher levels of child maltreatment are linked to difficulties in updating negative beliefs about strangers, as opposed to the intact ability to update negative feelings about friends.
Methods: Participants will complete a performance-based paradigm to test positive and negative updating of information about strangers and friends. The task involves an initial learning phase where participants observe images/facial expressions associated with positive or negative outcomes. The ability to update beliefs is assessed when the learning is reversed. In addition, they will be screened for trauma history, child maltreatment and cognitive flexibility.
Current status: We received the general IRB approval and aim to start the data collection in fall 2023.
Assessing intergenerational continuity of trauma and child maltreatment across cultures
Contact: Rachel Langevin (rachel.langevinATmcgill.ca)
Aim: Our group collaborates on projects related to the intergenerational continuity or transmission of trauma and child maltreatment across cultures.
Methods: In the short term, we are working on a systematic review which will synthesize the current knowledge on intergenerational continuity of child maltreatment in non-western countries. We are also identifying large existing data sets that could be used to answer key questions through secondary data analyses. Finally, we are preparing an outreach activity in Canada with the following objectives: (1) mobilizing and disseminating cutting-edge scientific knowledge to a wide-ranging audience; (2) fostering an engaging and constructive dialogue between key stakeholders in Quebec's child protection sector and international researchers; (3) formulating a research program for the upcoming five years.
Current status: Our systematic review is in the planning phase, identification of existing data sets is in progress. The outreach activity will take place in 2024 or 2025.
