While 22 percent say the pullout was an Israeli unilateral decision, only 15 percent believe it was the result of Palestinian diplomatic actions.
Some 1,360 people were questioned for the survey, conducted by An-Najah University in Nablus.
According to the study, 53 percent believe the Palestinian Authority should not gather weapons from the various factions; 42.5 percent say the PA must disarm the organizations.
However, 54 percent say the only necessary weapons needed in Gaza should be held by the PA.
An optimistic future
Those polled expressed optimism for Gaza's future following Israel's pullout - 71.5 percent said their economic situation would improve, while 47 percent fear Gaza will become an open-air prison. 44 percent believe Gaza will become a free and open territory.
Notably, 62 percent oppose all armed action against Israel, and 59 percent say they would only support action against Israel should it maintain control of the border crossings.
A majority of 80 percent believes Israel will continue to control the crossings and that the withdrawal was not a complete pullout.
Only 48 percent say the PA is serious in its intention to take control of the current security anarchy, while 44 percent think otherwise. Sixty-six percent say Palestinian security forces are part of the anarchy.
Primary goal to merge security forces
