Emotion-rich data is pre-requisite in the efforts of transferring emotional aspects of human communication into Human-Computer Interaction (HCI). An important facet of human social-affective interaction is its ability to facilitate social sharing of emotion, a fundamental part of the emotional processes. When conducted properly, such an interaction can give a positive effect to emotion-related problems. However, there is still a lack of resources that are: 1) explicitly designed for studying the emotional problems commonly encountered in everyday life, and 2) involving a professional as an expert in the conversation. In this paper, we present recordings of dyadic social-affective interactions between a professional counselor as an expert and 30 participants, summing up to 23 hours and 41 minutes of material. In each interaction, a negative emotion inducer is shown to the dyad, and the goal of the expert is to aid emotion processing and elicit a positive emotional change through the interaction. Specifically, we aim to observe how an external party can guide and facilitate emotion processing, especially after a negative emotional response in a commonly encountered social situation. The construction, development, and analysis of the database is detailed in this paper.
