Effects of condom availability on their use: a field experiment in a Peruvian hostal

Perú has a high rate of unintended pregnancies. STI rates grow. New policies are needed. Contextual factors in the condom use decision are understudied. Self-reported measures of use have proven unreliable. I used a hostal (love-motel) to conduct a field experiment. 102 couples were randomly allocated to three groups with different levels of condom availability. Instead of using self-reported measures, after a couple left, I searched their room for used condoms. Couples in rooms with a condom on the nightstand were 268% more likely to use one than the control group. For couples with a condom available at the reception desk, the increase was 176%. Facilitating condoms in hostales is a suitable strategy to decrease unprotected sex in the country.
