PurposeThe purpose of this study is to describe the implementation of a digital-based team coaching intervention aimed at improving team communication in the workplace through social network visualization. The study examined recipients’ perceptions of the intervention at two time points and assessed the temporal stability of various factors, including the intervention’s integrity, design, transferability, acceptance and the usability of the adopted visualization tool. The moderating role of digital usability was also evaluated.Design/methodology/approachFour team coaching sessions were delivered to 62 participants from seven teams across three departments within a large public health-care organization in Northern Italy. Perceptions of the intervention dimensions were collected after the second and fourth sessions.FindingsResults indicated that, at both time points, recipients appreciated the intervention’s integrity and usability more than its design, transferability and acceptance. Furthermore, no significant changes in recipients’ perceptions were observed over time. The transferability of the intervention was significantly associated with its acceptance, but only when the usability of the digital tool was high.Research limitations/implicationsThe study enriches existing literature on digital interventions in group communication by focusing on process dimensions like recipients’ perceptions of various aspects and the implementation process. Furthermore, the study underscores the potential of integrating specific techniques such as sociomapping and coaching within health-care organizations, encouraging more research and development in these areas.Practical implicationsThe study emphasizes the critical role of usability and integrity in digital-based team coaching interventions, suggesting that high-quality, user-friendly tools not only lead to initial effectiveness but also sustain positive impacts over time, while also increasing transferability and acceptance.Originality/valueThe present study uniquely deploys a longitudinal approach to examine recipients’ perceptions of a digital-based intervention that combines social network visualization and team coaching to enhance team communication.
