A model for assessing adult attachment

1. A model for assessingadult attachment John Kirkland*^ David Bimler^ Eva Klohnen^^ ^Massey University ^^University of Iowa

2. Some approaches Several approaches have been advanced for assessing Adult Attachment. These have to migrate into distinct “two cultures”: • Developmental • Social psychology/personality (see references for details)

3. Our approach, here We take a “social psychological/personality” approach here. This research is very much “in progress”. Our aim is to advance assessment through systematic review of an existing data base and offer an alternative model. A caveat: How this may correspond to facets of the “developmental approach” is beyond the scope of our current project.

4. The frame The starting point was a recent theoretical and measurement framework offered to accommodate the major approaches to adult attachment measurement and conceptualisation (Klohnen, 2005).

5. This frame accommodates Major social personality approaches: - two major dimensions – anxiety & avoidance - four “types” or “styles” Major developmental approaches: - security-insecurity and hyper- and deactivation (45 deg offset from anxiety and avoidance)

8. “Attachment” adjectives Based upon this 2-D framework, 8 adjectives were chosen for each octet from a representative pool of 196. It was thought these adjectives would be the best markers for these zones.

9. Examples Secure enthusiastic outgoing playful sociable warm optimistic cooperative contented

10. Examples Dismissing individualistic independent self-reliant tough stern indifferent unemotional harsh

11. Empirical test of 8 circumplex scales 1000 participants (Ps) rated all 196 adjectives using Likert scales. Computed scores for all 8-item scales for each P; standardised scores (mn=0,sd=1). Ps also completed independent attachment measures (eg obtained attachment style data).

12. Graphic outputs The following radar-like graphs show each of the four “attachment styles” scored on the 8 adjective scales. Thus, scores on all 8 scales can be displayed for visual inspection.

18. First impressions There is definitely a trend here – For instance, those selected items, placed within the eight groups do appear to fit into a theoretical attachment frame.

19. Our current approach For the present study we began from a different place. First, deleted 46 items from the 196, eliminating those which provided little contribution to the 4 attachment “types”. Then, by applying inter-item sorting routines we “mapped” these 150 items. This inter-item “semantic” map was subsequently adjusted (slightly) using the 1k Likert-based data set.

20. Some “maps” We now present some maps to represent various outcomes from our analyses. As a little warning, map viewing does require some spatial agility.

21. Map 1 “Items in space” Shows inter-relationships amongst items spread in 3-D, as if on the surface of a hollow sphere.

22. Map 1 – Item Points

23. Map 2 – Labelled Items

24. Map 3 We then apply “dimensions” for slicing the sphere into manageable sections. Dimensions can be shot through anywhere since the inter-item array itself does not change with alternative axes. Selected dimensions may be checked for face value by interpolating any item’s location along each dimension’s axis to see if this “makes sense”. Clearly, the “meaning” of these dimensions will be a function of their locations. But these are for illustrative purposes only and should not be taken as definitive. They are as “stepping stones” leading to a larger project.

25. Map 3 - Dimensions

26. Map 4 – Items marking this selection

27. Map 5 - Dimensions with all items

28. Map 6 Aligning the 8-item groups within the map itself. Any predictions?

29. Map 6 - Circumplex

30. Map 7 We can then compute vectors by multiple regression. We used published aggregated ratings from 7 “experts”. They provided Likert-like ratings for 196 adjectives for each of the classic “types”: dismissing, secure, preoccupied and fearful.

31. Map 7 - Vectors

32. Map 8 The map can be rotated to show there is a contribution of D3 (whatever that is) and this would have a bearing on interpretation. There is more work to be done on choosing optimal dimensions. This outcome suggests a 3-D circumplex rather than a 2-D one fits these data better.

33. Map 8 – Rotated for Vectors

34. Map 9 As an example of how “experts” and lay (the 1k Ps) persons differ in their word use, consider the spatial differences between experts’ vectors and the actual words. This outcome suggests a better fit between experts and lay participants will occur when those “troublesome” words (having the largest separation) are removed. This is what we did for our revised approach, see below.

35. Map 9 – Lay and Expert

36. Trilemmas As an alternative to Likert-like scales for data collection we propose trilemmas provide rich data for less work. Trilemmas are created by optimising equilateral triangles within the map. Each trilemma contains items that are uncorrelated. Within sets each item is listed once. Many parallel trilemma sets can be constructed by changing the combinations.

38. Map 10 For example, one expert completed 50 trilemmas for each of the 4 classic attachment styles. These results were plotted against the 7 expert prototype ratings (using Likert-type scales for all 196 adjectives). The next plot shows relevant outcomes.

39. Map 10 – Trilemmas and Likert

40. Where to go from here? Since the 1k participants involved with those 196 adjectives also provided other attachment information (such as from Hazan and Shaver’s instrument) it would be possible to select persons who matched predictions from this model for further analyses.

41. Further, more work is needed about the relevance of Dimension 3’s contribution to understanding attachment dynamics. Additionally, how can the new 3-D information contribute to revising the 2-D circumplex formulations?

42. Moreover, will this new 3-D conceptualisation allow us to extend our assessment and understanding of Adult Attachment on a broader level and therefore enable us to go beyond a purely social psychological/personality perspective?

43. Further, this research extends the current trend where research is moving away from a strictly categorical approach (here are x number of styles and shoe-horn people into these) and more towards a dimensional approach. One future challenge is to identify the relative strengths of both of these traditions and make them more complementary, as is done in the medical arena.

44. Finally, we believe this method will help to elucidate the relative strengths and weaknesses of existing approaches to adult attachment conceptualisation and measurement, incorporate them into a new, more inclusive model that can be empirically tested and validated with a view to extending theory and, ultimately, delivering sound practical field-applicable procedures.
