Descriptive Analytics
Typically, users stated having 2.step 1 (SD = 1.71) link couples and you may connecting just as much as half dozen times (SD = 8.5) previously 3 months. As a whole, 34.8% away from college students stated that have unsafe sex throughout the a hookup. 0%), perception intimately disappointed (39.0%), be sorry for that a hookup went too far (35.3%), and you will embarrassment (35.1%).
Dimensionality
A keen EFA considering facts that analysis were good enough unidimensional meet up with the brand new assumptions of one’s IRT study (RMSEA = .053, RMSR = .09, ? dos (119) = , CFI = .94, proportion of your first so you’re able to next eigenvalue = 5.5:1). The issues was basically positively loaded with the single foundation (factors packing .36 to .83). step 1
Product Fit
Defectively installing products was in fact eliminated about size predicated on fit plots and you will modified ? 2 /df percentages (Stark, Chernyshenko, & Drasgow, 2005). Adjusted ? dos /df percentages greater than around three to have unmarried, double and you will triplet circumstances was indeed individuals to have removal (Drasgow, Levine, Tsien, Williams, & Mead, 1995). A single items “You will find sensed upset one a connection didn’t generate me personally feel great on the me personally the next day” is deleted considering bad goods match.
Table 1 gift ideas the new parameter quotes and you can fundamental errors of your own kept sixteen circumstances. Items slopes (a) varied off 0.69 so you can dos.84. The spot parameters (b) ranged regarding 0.14 (regretting a hookup) to help you dos.73 (employing an enthusiastic STI). IIFs and you can item discrimination (a) was in fact checked to determine points to be employed throughout the finally level. Items that got low discrimination and lowest items guidance was basically candidates to possess deletion, and two situations (“We have alarmed which i may have obtained pregnant otherwise acquired my personal hookup lover pregnant” and you can “My friends has actually teased me personally regarding the a connections.”) were eliminated in the measure (a beneficial = 0.69 and 0.87 correspondingly). Removing these items throughout the scale had little affect the brand new limited accuracy to own ? (16 issues r = 0.78 and 14-activities r = 0.76). The last fourteen-item type had acceptable degrees of reliability and you may fundamental error of aspect ( Shape step 1 ). The fresh new size are most reliable during the evaluating bad outcomes for men and women whoever ? dropped amongst the imply (? = 0; r = .85) and you will step 1.5 basic departure above the indicate (? = step one.5; r = .84).
Take to pointers and you will standard error out of dimensions properties for fourteen-item size. Strong range means overall information; dotted range ways practical mistake. Theta is actually plotted off 2 SD underneath the imply to three SD over 
the mean.
Differential Product Performing
IRTLRDIF was utilized to determine five point circumstances (situations 4, 8, a dozen, and you can fourteen). By using these anchor activities, i understood six even more products that was in fact DIF 100 % free (facts 1, step three, 5, eight, 10, 13) and you will five products with DIF (activities 2, six, 9, 11). All activities showed tall DIF throughout the b parameter (difficulty), however the latest ? factor (discrimination). The final calibration of four activities with DIF try shown within the Desk 2 . Inside for each and every instance, guys expected high amounts of the latest latent feature to endorse the item. For example, when you’re ladies that has a latent characteristic get everything 0.65 SD above the mean got a great fifty% likelihood of demonstrating they’d considered disappointed one to a relationship mate has not yet called her or him following link, guys with a hidden trait score around a few SD over the suggest got a fifty% odds of endorsing the same product.
Table dos
Both for male and female students, the number of linking bad influences was absolutely synchronised with number of connections people, r(284) = .33, p Dining table step three ). Meant for the new standards-relevant legitimacy of your own NIHI, members who reported that have involved with unsafe sex at least once during the a relationship before three months advertised higher bad relationship outcomes (Yards = cuatro.forty-eight, SD = step three.46) than youngsters just who did not have unsafe sex (Meters = dos.72, SD = 2.71), t(six05) = 6.89, p ***
