Public relations outcomes were the least well predicted outcome by the regression analyses, with only 21% and 15% of the variance explained in challenging and simple projects, respectively.
Team harmony, the clear empowerment of the team leader, an empowering team leadership style, effective inter-agency engagement, interdisciplinary collaborative teamwork while developing
the purpose and need, greater public influence on the process, and a lack of turnover of the team leader were all associated with more positive public relations outcomes.
