This research examines how maternal self-efficacy develops during matrescence, the transition to motherhood. Through interviews with new mothers and analysis of the SPACE programme, it shows that confidence in parenting grows not from perfection but from supportive environments, highlighting the need to rebuild community support for new mothers.

This PhD defense presents computational approaches to human behavior across two domains. First, a construct-mining pipeline uses open-ended responses, sentence embeddings, debiasing, HDBSCAN clustering, and intrusion validation to derive a data-driven taxonomy of emotion regulation strategies. Second, mixed-methods and classifiers analyze German Twitter, linking counter-speech styles to hate reduction at scale.

This research investigates why people struggle with interpersonal problem-solving, especially in the context of psychological disorders. Using surveys and the MEPS task with 160 participants, the study found that emotion-regulation difficulties and experiential avoidance explain 46% of poor problem-solving. Improving emotional acceptance may significantly enhance responses to interpersonal conflict.
