Description

<p>Aim: This study aimed to examine the reliability and validity of the Team Approach Assessment Scale (TAAS), which assesses a team approach based on individual perceptions, to develop a revised version (TAAS- Revised Edition) using an interdisciplinary team.</p><p>Method: An anonymous, cross-sectional questionnaire survey was conducted using TAAS on medical professionals at three general hospitals in prefecture A. The alpha coefficient was calculated for the scale’s reliability, and exploratory factor analysis (EFA) was conducted for validity. This study was carried out after being approved by research ethics reviews at the facility to which the researcher belongs and cooperating research facilities.</p><p>Results: There were 789 valid responses with a response rate of 27.1%. The EFA results yielded a 5-factor structure with 22 items using the maximum likelihood method and promax rotation. The factors of TAAS-R changed from four to five. There were nine items for “team functions,” five items for “contributions to team,” three items for “importance of team activities,” three items for “team member role performance,” and two items for “clarification of goals and roles.” The alpha coefficient for the overall scale was 0.93, while the scope of each factor had a range of 0.68–0.91.</p><p>Conclusion: This study almost confirmed the reliability and validity of the resulting TAAS-Revised Edition with a 22-item, 5 factor structure.</p>
