Detailed Analytics

An average of, users reported having dos.step one (SD = step 1.71) relationship people and you can hooking up whenever half a dozen moments (SD = 8.5) prior to now 3 months. Altogether, 34.8% regarding students said having unprotected sex throughout the a connections. 0%), feeling intimately unsatisfied (39.0%), feel dissapointed about that a relationship went too much (thirty five.3%), and you can embarrassment (thirty five.1%).

Dimensionality

An EFA provided proof one data was sufficiently unidimensional in order to meet the fresh assumptions of your IRT research (RMSEA = .053, RMSR = .09, ? dos (119) = , CFI = .94, proportion of the earliest in order to 2nd eigenvalue = 5.5:1). All affairs have been seriously piled into solitary foundation (facts packing .thirty-six so you can .83). 1

Items Fit

Defectively fitted points have been eliminated from the measure according to match plots and you will adjusted ? dos /df percentages (Stark, Chernyshenko, & Drasgow, 2005). Adjusted ? dos /df ratios higher than around three to own single, twice and you can triplet circumstances was basically individuals to possess removal (Drasgow, Levine, Tsien, Williams, & Mead, 1995). One items “I have experienced upset one a link didn’t create me be more confident in the me the very next day” try deleted according to bad goods complement.

Table step one gift ideas the newest parameter estimates and you will fundamental problems of the kept sixteen affairs. Goods slopes (a) ranged away from 0.69 so you can dos.84. The spot parameters (b) ranged regarding 0.fourteen (regretting a hookup) to help you 2.73 (employing an STI). IIFs and you may goods discrimination (a) was checked to understand what to be chosen about finally level. Products that had lower discrimination and lower goods suggestions was people to possess removal, and two circumstances (“You will find worried which i could have acquired expecting otherwise acquired my personal link lover expecting” and you will “My buddies has teased myself on a relationship.”) were eliminated regarding scale (a beneficial = 0.69 and you can 0.87 correspondingly). Deleting these items from the level got little influence on the latest marginal accuracy to possess ? (sixteen circumstances r = 0.78 and 14-points roentgen = 0.76). The past 14-items version had acceptable quantities of reliability and you will important error away from aspect ( Shape step one ). The new size was best on determining bad results for men and women whose ? fell amongst the mean (? = 0; roentgen = .85) and you can step 1.5 fundamental departure over the imply (? = 1.5; roentgen = .84).

Try recommendations and you can basic mistake away from measurement features getting fourteen-item scale. Strong range means complete guidance; dotted range means practical mistake. Theta was plotted from dos SD beneath the indicate to three SD over the mean.

Differential Product Functioning

IRTLRDIF was utilized to spot five point things (items 4, 8, a dozen, and 14). By using these anchor items, i known half a dozen a lot more products that have been DIF 100 % free (situations step one, step 3, 5, eight, ten, 13) and you may four points having DIF (things dos, six, nine, 11). All four situations demonstrated significant DIF in the b parameter (difficulty), yet not the fresh ? factor (discrimination). The past calibration of your own five situations that have DIF was revealed when you look at the Dining table dos . In for every case, men necessary large amounts of the latest hidden trait so you can promote the object. Eg, when you’re ladies who’d a hidden trait score as much as 0.65 SD above the imply got a great fifty% probability of showing they’d noticed troubled that a connection lover hasn’t called them pursuing the connections, boys with a hidden characteristic get to a few SD over the mean had an effective fifty% probability of endorsing a comparable item.

Desk 2

For both female and male college students, the complete amount of connecting negative has an effect on is absolutely coordinated with number of link couples, r(284) = .33, p Dining table step three ). Meant for the fresh new standard-relevant legitimacy of your own NIHI, members which reported with involved with unprotected sex at least one time while in the a hookup prior to now 90 days advertised better negative link outcomes (M = cuatro.forty eight, SD = step three.46) than people just who didn’t have unsafe sex (Meters = dos.72, SD = 2.71), t(605) = six.89, p ***
