    Background Between 2004–2007 there was a relative reduction of partner physical violence of 50% (17.5% vs 8.5%), in Medellin, Colombia.

    Aims/Objectives/Purpose To determine factors associated with intimate partner physical violence decreasing in Medellin Colombia, (2004–2007).

We calculated the mean annual change in intimate physical violence, using percentage of aggressors and CI 95%. Logistic regression was used to estimate the relationship between change in physical violence and associated factors.

    Results/Outcomes Factors associated with this change were an increase of collective efficacy (B=3.3; SE=1.0), and reduction in the following: past year unemployment (B=−0.06; SE=0.12); perceived neighborhood disorder (B=−1.4, SE=0.66), distrust (B=−2.0; SE=1.1), violence and interpersonal aggression legitimating (B=−1.5, SE=0.12), frustrated expectancies and tolerance of law breaking reduction.
