Best fitting risk model for sexual hookup behaviors. Lack of planning: lpl1, lpl2, lpl3 are 3 parcels for lack of planning. Sensation Seeking: ss1, ss2, ss3 3 parcels for sensation seeking. Negative urgency: nur1, nur2, nur3 are 3 parcels for negative urgency. Factor loadings for parcels were removed from figure for conciseness, but all were p<.001. Non-significant pathways were removed from the model for clarity. Dotted lines represent indirect effects. *p<.05. **p<.01
