Procedures
In order to finest address any possible biases due to attrition in the longitudinal analyses, complete imputation restriction probability (FIML) tips were utilized that have analyses, in addition to all of the parameters that were pertaining to future shed studies (we.elizabeth., in which analysis were not missing totally randomly). Mainly because strategies have been discovered to yield minimum of biased prices when all of the available investigation can be used for longitudinal analyses (vs. listwise deletion from missing study), the entire unique attempt from 185 toward huge analysis is actually useful these types of analyses. It huge decide to try ergo has the greatest quotes regarding growth and alter during the externalizing decisions and you will depressive attacks and you can is minimum likely to be biased because of the forgotten investigation. e., listwise deletion) yielded overall performance that were dramatically just like those people reported lower than. In the contribution, analyses suggest that attrition try small overall and never gonna has distorted some of the findings advertised. Analyses as well as showed that players getting who correspondence investigation which have dads was basically offered had large family unit members profits, was indeed less inclined to getting people in a great racial/cultural minority group, and was in fact expected to getting securely affixed than simply users having who dad communication investigation weren’t offered.
Mature attachment interview (AAI) and you may Q-lay (George, Kaplan, & Head, 1996; Kobak ainsi que al., 1993)

It prepared interview probes individuals’ definitions of its teens relationships having mothers in conceptual terms with asks for specific support recollections. Particularly, sufferers was basically expected so you can list five terms discussing their early youngsters relationships with each mother or father after which to spell it out particular episodes that mirrored the individuals conditions. Most other inquiries focused on particular instances of troubled, separation, losses, trauma, and you will rejection. In the long run, the interviewer asked professionals to incorporate a lot more integrative descriptions of alter within the relationship that have mothers plus the ongoing state of these relationships. Brand new interviews contains 18 inquiries and live one hour toward average. Limited changes towards the mature version have been made to make the questions natural and simply understood for an adolescent populace (Ward & Carlson, 1995). Interview had been audiotaped and you can transcribed to have coding.
The brand new AAI Q-set (Kobak et al., 1993) was created to closely synchronous the fresh Adult Accessory Interviews Classification System (Chief & Goldwyn, 1998) however, so you can give continued tips from properties out of accessory providers. Each rater understand good transcript and you will provided an effective Q-sort description by delegating 100 products toward nine groups between really so you’re able to minimum feature of interview, playing with a pressured shipment. The interviews was in fact thoughtlessly rated by the no less than two raters having detailed training in the Q-kinds together with Adult Connection Interviews Group System.
These Q-sorts were then compared with a dimensional prototype sort for secure versus anxious interview strategies, reflecting the overall degree of coherence of discourse, the integration of episodic and semantic attachment memories, and a clear objective valuing of attachment. The individual correlation of the 100 items of an individual’s Q-sort with a prototype sort for a maximally secure transcript was then used as that participant’s scale security score (ranging from ?1.00 to 1.00). The Spearman-Brown interrater reliability for the final security scale score was.82. This system was designed to yield continuous measures of qualities of attachment organization rather than to replicate classifications from the Main and Goldwyn (1998) system. Prior work has compared the scores obtained within this lab to a subsample (N = 76) of adolescent AAIs that were classified by an independent coder with well-established reliability in classifying AAIs (U. Wartner) We did this by converting the Q-sort scales described above into classifications using an algorithm described by Kobak et al. (1993). Using this approach, we obtained an 84% match for security versus insecurity between the Q-sort method and the classification method (K = .68). Prior research in adolescent samples has also indicated that security is highly stable over a two-year period (i.e., r = .61) (Allen, McElhaney, Kuperminc, & Jodl, 2004). We also considered employing a category available for coding adolescents’ use of hyperactivating versus deactivating strategies in the interview, but given that its high inverse correlation with attachment security (r = .78, p < .0001) suggested it would be supplying largely redundant information, it was not analyzed further.
