Partnership to the partnership is measured that have 8 products, modified from the funding design level (Rusbult et al

Of your players, 128 (58.7%) turned into parents anywhere between T2 and T3, 58 (26.6%) ranging from T3 and you may T4, and you will 32 ranging from T4 and T5 (fourteen.7%). The new analysis category contains 110 professionals (33.5%) which didn’t have students during the study. There can be a fairly lowest attrition price in this longitudinal study. During the T2, 320 of the 1st 328 partners nevertheless participated in the study, T3 contained 310 professionals, T4 from 268, and T5 from 240 (73.2% of one’s test from the T1).

The brand new suggest chronilogical age of husbands try decades (SD = cuatro.81) therefore the imply age of wives is ages (SD = 4.34) during the T1. Lovers got romantically with it for 5.75 many years (SD = 3.05) an average of together with started traditions with her getting normally step 3.66 age (SD = 2.20) within T1. Nearly all couples met with the Dutch nationality (97.6% of the husbands and you will 94.5% of one’s wives).
