step three.1 Internal framework
The assumed four-factor model of the ARI-CP 2–5 was tested in the survey dataset (N = 446), by means of a CFA (see Figure 1). All fit indices of the tested model-? 2 (df) = 2, (1,074), RMSEA = 0.057, CFI = 0.960, TLI = 0.958, and GFI = 0.962-indicate sufficient model fit according to the guidelines of Hu and Bentler ( 1999 ). We did not allow for any error terms to covary. Some items have factor loading of <.30. Removal of these items resulted in a worse model fit, therefore, these items were kept.
Furthermore, we checked about three alternative design structures. The first option design are a single-grounds design, with items used in that complete connection factor. The one-factor model resulted in an even worse design fit compared to thought four-grounds design, ? dos (step 1,080) = 2,, RMSEA = 0.074, CFI = 0.933, TLI = 0.930, and GFI = 0.946. The second choice model is actually both-grounds safe/insecure model, and this produced another match indices: ? dos (step one,079) = 2,, RMSEA = 0.065, CFI = 0.948, TLI = 0.946, and you may GFI = 0.955. The next option design was the 2-grounds arranged/unpleasant design, and therefore put the second match indicator: ? dos (step one,079) = dos,, RMSEA = 0.071, CFI = 0.938, TLI = 0.935, and you may GFI = 0.950. The final choice basis is the three-foundation safe/organized-insecure/unpleasant, which have ? dos (step 1,077) = dos,, RMSEA = 0.063, CFI = 0.951, TLI = 0.949, and you can GFI = 0.957. All of the solution activities had a bad match as compared to presumed four-basis design. Ergo, i continued for the five-factor model.
step three.2 Dimensions invariance
Next, i checked to possess measurement invariance anywhere between dads (N = 211) and you can parents (N = 235), guys (N = 225) and you may ladies (N = 221), 2 to 3-seasons olds (Letter = 259), and you will cuatro- so you’re able to 5-12 months olds (N = 186), and across parents from a general populace decide to try (N = 378) and you will a clinical test (N = 68). We come which have comparison if the configural patterns per multigroup CFA will have adequate design complement. Each step of the process a while later (thresholds model, loadings, and you may intercepts design) had a lot more strict conditions getting measurement invariance. Table step 1 gift ideas the outcomes of one’s dimensions invariance analyses.
- an excellent Normgroup consisted of N = 378 caregivers on the general society shot.

The fresh configural model investigations dimension invariance getting sex of the caregiver displayed sufficient design complement, appearing your preferred items of one’s ARI-CP dos–5 was in fact of same products across moms and dads. For each and every adopting the action lead to a decrease inside the CFI away from less than .005, exhibiting that even more stringent requirements had been came across. It indicates the common activities of your own ARI-CP dos–5 have a similar meaning round the mothers and fathers (metric invariance), and that group mode will likely be meaningfully compared round the mothers and you may fathers (scalar invariance). While doing so, the results indicate configural, metric, and you may scalar invariance getting intercourse of one’s child, chronilogical age of the kid, and you can populace method of.
3.3 Accuracy
We have looked at this new ordinal alphas to the ARI-CP 2–5 scales. Ordinal leader try .78 getting Avoidant connection, .89 to possess Secure accessory, .85 getting Ambivalent connection, and .89 having Messy attachment. The inner surface of your ARI-CP 2–5 balances is actually thus enough.
The concordance between caregivers of the identical boy was checked out in the a good subgroup regarding 63 caregiver pairs one filled out the latest ARI-CP 2–5 comparable guy. The fresh correlations between caregivers of the identical boy into the Safer, Avoidant, and you will Ambivalent size was indeed extreme, r = .42, p = .001; r = .42, p = .001; and you may r = .39, p = .002, respectively. This new correlation involving the caregivers of the identical boy of one’s Sloppy measure wasn’t tall, roentgen = .08, p = .557.
