Intergenerational attachment orientations: Gender differences and environmental contribution.

ABSTRACT: After more than four decades of research and almost 100 attachment studies, the mechanisms of intergenerational transmission of attachment still remain unclear. To better understand the mechanisms moderating the associations of attachment orientations from one generation to the next, this empirical study examined the roles of 1) shared and non-shared environmental factors that characterize critical events in adulthood such as career choice, income and child care; 2) gender differences in attachment between parents (Generation 1, G1) and their adult offspring (Generation 2, G2) and their possible interactions. A sample of 321 families with G2 adults aged 18 and over and two G1 parents up to the age of 81 took part in this study. Both generations completed the Experiences in Close Relationships attachment measure as well as a comprehensive detailed measure of current core characteristics in adulthood (e.g. employment status, income, whether they had children) and demographic variables (gender, age). The findings suggest that the associations between the attachment orientations of G1 and the attachment orientations of G2 were moderated by G2's income, their G1 paternal income and employment status, whether G2 had children (G3) of their own, and their family status after controlling for the age of G2, and the age of both paternal and maternal G1. When the associations for both paternal and maternal G1attachment orientation with both their male and female G2 was analyzed separately, this accounted for 35% of the variance of males' G2 attachment orientation. The discussion focuses on the contribution of these findings to attachment theory and draws clinical conclusions.

Project description:PurposeThis study was carried out to investigate the accuracy of referring different locations of the patellar tendon attachment site and the geometrical center of the osteotomy surface for tibial rotational alignment and observe the influences of gender differences on the results.MethodsComputed tomography scans of 135 osteoarthritis patients (82 females and 53 males) with varus deformity was obtained to reconstruct three-dimensional (3D) models preoperatively. The medial boundary, medial one-sixth, and medial one-third of the patellar tendon attachment site were marked on the tibia. These points were projected on the tibial osteotomy plane and connected to the geometrical center (GC) of the osteotomy plane or the middle of the posterior cruciate ligament (PCL) to construct six tibial rotational axes (Akagi line, MBPT, MSPT1, MSPT2, MTPT1 and MTPT2). The mismatch angle between the vertical line of the SEA projected on the proximal tibial osteotomy surface and six different reference axes was measured. In additional, the effect of gender differences on rotational alignment for tibial component were assessed.ResultsRelative to the SEA, rotational mismatch angles were - 1.8° ± 5.1° (Akagi line), - 2.5° ± 5.3° (MBPT), 2.8° ± 5.3° (MSPT1), 4.5° ± 5.4° (MSPT2), 7.3° ± 5.4° (MTPT1), and 11.6° ± 5.8° (MTPT2) for different tibial rotational axes in all patients. All measurements differed significantly between the male and female. The tibial rotational axes with the least mean absolute deviation for the female or male were Akagi line or MSPT, respectively. There was no significant difference in whether the GC of the osteotomy surface or the midpoint of PCL termination was chosen as the posterior anatomical landmark when the medial boundary or medial one-sixth point of the patellar tendon attachment site was selected as the anterior anatomical landmark.ConclusionWhen referring patellar tendon attachment site as anterior anatomical landmarks for tibial rotational alignment, the influence of gender difference on the accuracy needs to be taken into account. The geometric center of the tibial osteotomy plane can be used as a substitute for the middle of the PCL termination when reference the medial boundary or medial one-sixth of the patellar tendon attachment site.
