More than 1,000 people took part in the survey, examining South Yorkshire Police's operation both before and after March 4th's meeting between the two clubs.
The results, published today, "paint a damning picture" according to a statement issued by the organisation with 72.6 per cent of respondents saying the policing was worse than at previous derbies.
Nearly 71 per cent described the organisation of the exit from the stadium as "very poor", with less than five per cent labelling it "good" or very good".
Amanda Jacks, the FSF's director of casework, said: “There is no doubt that the results of this survey should give all stakeholders ample food for thought.
“Unfortunately, South Yorkshire Police’s approach did not meet supporters’ expectations of how a modern high-profile fixture should be handled. Supporters have expressed serious concerns about the force’s communication, conduct and approachability."
When asked how the policing of the the game could be improved, over two thirds of those taking part called for SYP to have "more proactive interaction" with fans.
Noting how 65 per cent felt supporters should be more involved in pre-game planning, Jacks insisted this confirmed both Wednesday and United fans wanted to work with rather than against the force. An independent advisory group, involving representatives of both clubs' support bases and officers, was established earlier this season.
"Notwithstanding their views of policing, it’s clear that supporters want a relationship with South Yorkshire Police," she added. "There are countless benefits, demonstrated by many derbies across the country, to including supporters in planning around major fixtures – this is the one positive to come out of all of this and South Yorkshire Police should listen to their community."
In an interview with The Star, conducted after the goalless draw, Deputy Chief Constable Mark Roberts pledged to "listen" to fans' concerns about the events organisation.
DCC Roberts, the national lead for football policing, also addressed claims that logistical failures had contributed to clashes outside the ground following the final whistle.
"I think, with any big operation, you tend to do a review," he said, speaking before the FSF's released its report. "We've picked up feedback. We've considered the whole game, pre-match, during the match and post-match. It's to see what went well and what didn't, what we could do better."
