Therapist Self-Disclosure as a Natural Language Processing Task

Proceedings of the 9th Workshop on Computational Linguistics and Clinical Psychology (CLPsych 2024)

Therapist Self-Disclosure (TSD) within the context of psychotherapy entails the revelation of personal information by the therapist. The ongoing scholarly discourse surrounding the utility of TSD, spanning from the inception of psychotherapy to the present day, has underscored the need for greater specificity in conceptualizing TSD. This inquiry has yielded more refined classifications within the TSD domain, with a consensus emerging on the distinction between immediate and non-immediate TSD, each of which plays a distinct role in the therapeutic process. Despite this progress in the field of psychotherapy, the Natural Language Processing (NLP) domain currently lacks methodological solutions or explorations for such scenarios. This lacuna can be partly due to the difficulty of attaining publicly available clinical data. To address this gap, this paper presents an innovative NLP-based approach that formalizes TSD as an NLP task. The proposed methodology involves the creation of publicly available, expert-annotated test sets designed to simulate therapist utterances, and the employment of NLP techniques for evaluation purposes. By integrating insights from psychotherapy research with NLP methodologies, this study aims to catalyze advancements in both NLP and psychotherapy research.

Proceedings of the Seventh Workshop on Computational Linguistics and Clinical Psychology: Improving Access

We introduce a large set of Hebrew lexicons pertaining to psychological aspects. These lexicons are useful for various psychology applications such as detecting emotional state, well being, relationship quality in conversation, identifying topics (e.g., family, work) and many more. We discuss the challenges in creating and validating lexicons in a new language, and highlight our methodological considerations in the data-driven lexicon construction process. Most of the lexicons are publicly available, which will facilitate further research on Hebrew clinical psychology text analysis. The lexicons were developed through data driven means, and verified by domain experts, clinical psychologists and psychology students, in a process of reconciliation with three judges. Development and verification relied on a dataset of a total of 872 psychotherapy session transcripts. We describe the construction process of each collection, the final resource and initial results of research studies employing this resource.
