An average of, members said having 2.step one (SD = 1.71) connection lovers and you can linking just as much as half dozen times (SD = 8.5) in the past 90 days. Overall, 34.8% regarding students advertised with unsafe sex through the a relationship. 0%), effect sexually unsatisfied (39.0%), feel dissapointed about that a hookup went past an acceptable limit (thirty five.3%), and shame (thirty-five.1%).
An EFA given research you to investigation were good enough unidimensional in order to meet brand new presumptions of your IRT analysis (RMSEA = .053, RMSR = .09, ? 2 (119) = , CFI = .94, ratio like tids of your basic so you’re able to second eigenvalue = 5.5:1). All of the points was seriously piled toward single factor (items loading .thirty six so you can .83). step one
Poorly suitable affairs was indeed got rid of from the measure based on match plots and you can modified ? 2 /df rates (Stark, Chernyshenko, & Drasgow, 2005). Adjusted ? dos /df ratios higher than three to own solitary, double and triplet situations had been individuals to possess deletion (Drasgow, Levine, Tsien, Williams, & Mead, 1995). An individual product “You will find experienced upset you to a hookup failed to make myself feel a lot better about myself the next day” is actually deleted according to terrible item complement.
Dining table step one presents the brand new parameter estimates and you will simple problems of your kept sixteen circumstances. Item mountains (a) ranged off 0.69 so you’re able to 2.84. The spot parameters (b) varied out of 0.14 (regretting a connections) so you can 2.73 (contracting an enthusiastic STI). IIFs and you may item discrimination (a) was tested to spot things to be retained on latest level. Products which had reduced discrimination and you can reasonable product advice was people for removal, as well as 2 activities (“We have alarmed which i might have obtained pregnant or gotten my personal connection spouse expecting” and you may “My friends features teased me personally in the a connections.”) were removed on the level (a good = 0.69 and 0.87 respectively). Removing these materials regarding scale had nothing affect the fresh marginal reliability for ? (sixteen affairs roentgen = 0.78 and you can 14-things r = 0.76). The past 14-item variation got acceptable levels of accuracy and you may fundamental mistake of measurement ( Contour step one ). The scale try most reliable from the determining bad results for those people whose ? decrease between the imply (? = 0; roentgen = .85) and you will step 1.5 standard departure over the imply (? = step one.5; roentgen = .84).
Attempt guidance and you will basic error away from aspect services to possess fourteen-item measure. Strong line suggests overall information; dotted line indicates simple error. Theta try plotted away from dos SD beneath the imply to three SD above the suggest.
Differential Goods Doing work
IRTLRDIF was used to determine five point points (products cuatro, 8, twelve, and fourteen). With your point facts, we known six most products that were DIF totally free (things step 1, step 3, 5, 7, 10, 13) and five facts with DIF (issues dos, 6, nine, 11). All activities demonstrated extreme DIF regarding the b parameter (difficulty), not the newest ? factor (discrimination). The final calibration of four products having DIF is actually revealed from inside the Table dos . In the for each instance, men requisite large levels of the fresh new latent characteristic so you’re able to recommend the item. Particularly, whenever you are people who’d a hidden characteristic rating whenever 0.65 SD above the mean had an effective fifty% probability of appearing that they had considered upset one a connections partner has not called him or her adopting the hookup, men which have a hidden feature rating doing several SD above the indicate got a beneficial fifty% probability of endorsing an equivalent product.
Dining table 2
For both male and female people, the quantity of hooking up bad influences is positively coordinated with amount of hookup people, r(284) = .33, p Dining table 3 ). In support of brand new expectations-relevant authenticity of NIHI, users exactly who stated having engaged in unprotected sex one or more times during a connections previously 90 days claimed better bad connection effects (Meters = cuatro.forty-eight, SD = step three.46) than just students just who didn’t have unprotected sex (M = 2.72, SD = dos.71), t(six05) = 6.89, p ***
