The survey of more than 1,000 interims found that more than a third (35%) of interims have completed an assignment abroad in the past year, compared to just a fifth (21%) the year before.
Over half (60%) of interims responding to the survey also said they had been engaged on assignments in Europe in the past 12 months. Asia and Australasia (21%), North America (17%) and the Middle East (15%) were also common destinations.
The survey revealed that many overseas assignments were focused on growth and high performance, with the inflation of projects (26%), addressing internal change (26%), business development (18%) and driving quality and performance (17%) some of the most frequent desired outcomes.
It also found that assignments within the UK tended to be crisis-driven, with 40% of interims stating that the primary outcome of their last UK assignment was to support a transformation or turnaround programme.
Mike Hollin, CEO, Alium Partners said: "There is a definite sense that the number of overseas interim placements is on the up.
"Nothing demonstrates more clearly the value of interims than that the companies in which they are placed are so keen to extend their contracts or employ teams of interims.
"It is also interesting to see an increasing number of interims reporting that they have are replacing management consultants, showing a definite shift in market behaviours towards the expertise and delivery of the interim."
