the Team as Secure Base (TASB) Questionnaire

Description

The Team as Secure Base (TASB) Questionnaire, developed by Behrova & Biggart in 2025, is designed to measure perceptions of secure base function within work teams. The TASB model, as proposed by Biggart et al. (2017), suggests that team availability, reliability, and sensitivity foster reassuring internal mental representations, indicating that the team can provide support during challenging times. This questionnaire was created due to the limited number of existing measures that assess the presence of TASB within a team.

The development of the questionnaire involved generating items from Biggart et al. (2017), conducting original interviews with child and family social workers, performing a literature review, and gathering responses from experts using the Delphi method. Over three phases, social work experts provided both qualitative and quantitative data to evaluate the content validity of the items. The final questionnaire consists of 207 items and is designed to capture five dimensions of TASB for supervisors and co-workers. The authors reported results concerning the content validity of the items and noted that factor analysis is needed to further reduce the item pool.
