    Objective. In today’s workplaces an increasing number of tasks is completed in teams. Hence, to understand the psychological processes affecting interaction within and success of teams in different environments is of great importance. To study these processes, a new TT10 questionnaire (84 questions, 10 separate subscales) was created. The aim of this thesis was to study the validity and reliability of the TT10 by studying multiple literature-based hypotheses about connections between the subscales of the TT10 in two separate studies. Methods. In study 1 (n=49) 10 teams from two Finnish technology companies filled the TT10 and basic demographic information online. In study 2 (n=124) there were 62 pairs consisting of an employee of a Finnish insurance company and a customer. The counterparts in each pair were anonymously in contact with each other in an online chat for 20 minutes during which their task was to solve puzzles together. After the experiment they were asked to review the interaction of their pair with a shortened version (27 questions) of the TT10. Results. Almost all of the hypotheses gained support. Different subscales were in connection with each other mostly in the hypothesized ways. Conclusions. The most promising subscales of the TT10 were psychological safety, social cohesion, collaboration, and co-flow. However, limitations such as a very limited number of participants in study 1 made some of the results a bit unclear. However, according to these preliminary results, the TT10 seems to be a promising questionnaire that still needs fine-graining.
