Recognizing that collaboration in the context of intervention is, first, relevant, and second, that it has been mainly studied from an interdisciplinary perspective, this study, situated in Chilean Social Work, looks at intradisciplinary collaboration, specifically between professionals and technicians in Social Work. It seeks to answer, among other questions, to what extent the interveners' institutional, organizational, and personal aspects would influence intradisciplinary collaboration. Methodologically, based on a quantitative questionnaire, answered by professionals and technicians in Social Work in Chile and using a multiple linear regression model, this work answers the questions that have guided it. In terms of results, it is noted that these elements would undoubtedly explain the collaboration quantitatively. Among its conclusions, the need to strengthen institutional and organizational conditions to favor meaningful cooperation in pursuit of intervention is noted.
