“…In contrast with adult studies, twin studies in infants and preschoolers found modest (O'Connor & Croft, 2001) or negligible (Bakermans-Kranenburg, van Ijzendoorn, Bokhorst, & Schuengel, 2004;Bokhorst et al, 2003;Roisman & Fraley, 2008) genetic influence on attachment. A similar conclusion was reached by Ricciuti (1992), who combined the samples of some small pioneer studies of 12-to 22-month-old twins assessed with the SS and did not find evidence of genetic influence.…”

The relative contribution of genetic and environmental influences to individual differences in attachment security is still incompletely understood. We assessed attachment style with the Experiences in Close Relationships questionnaire in a volunteer sample of 677 twins (43% male) ages 23-24 years drawn from the population-based Italian Twin Register, who belonged to 244 complete pairs (46% monozygotic) and 189 unmatched pairs. Genetic structural equation modeling was performed with the Mx program. Genetic effects accounted for 45% and 36% of individual differences in attachment-related anxiety and avoidance, respectively. Furthermore, the covariation between anxiety and avoidance was found to be mainly due to genetic factors, with heritability of the latent attachment security phenotype estimated at 62%. Unshared environmental factors explained the remaining proportion of variance. Although our findings are best regarded as preliminary given some study limitations, they suggest that both nature and nurture contribute to individual differences in adult attachment.

“…This small sample technique provides depth rather than generalizability and is particularly appropriate for sensitive topic research. 35,[39][40][41][42] Qmethodology has been extensively used in qualitative psychological research to understand human behavior, 39,[43][44][45][46] workplace behaviors, 41,47 among others. Therefore, in a relatively unexplored area like PWU, this technique can provide insights into the underlying dynamics of perceptions of the actors.…”

An important aspect to managing Personal Web Usage (PWU) at the workplace lies in understanding and reshaping the perceptions of the users. The study contends that the outward manifestation of PWU behaviors at the workplace is but one consequence of the actors' attitudes which in turn are determinants of their ingrained beliefs. This study explores user perceptions about PWU using a web-based Q-methodology. Q-methodology used in this study is suitable for exploratory research, to obtain a deeper and first-hand understanding about the underlying phenomena about an under-explored concept. Twenty-five participants were asked to sort 38 statements according to their relative importance. The results uncover three distinct factors PWU: (1) cyber-bureaucrat, (2) cyber-humanist, and (3) cyber-adventurer. This indicates that PWU maybe a multidimensional construct instead of a uni-dimensional one as previously thought. The findings of this study can help managers understand, and shape the perceptions of the users rather than the outwardly manifested behaviors.

“…The other available twin studies of attachment have all tested for heritable effects in children (Bakermans-Kranenburg, van IJzendoorn, Schuengel, & Bokhorst, 2004;Bokhorst et al, 2003;O'Connor & Croft, 2001). These studies used different assessment methods that include the Strange Situation (Ainsworth et al, 1978), the Attachment Q-Sort (Vaughn & Waters, 1990;Waters, 1995) and Cassidy and Marvin's (1992) preschool coding manual for behaviour in the Strange Situation.…”

Insecure attachment and personality disorder: a twin study of adults

This study used 239 twin pairs from a volunteer community sample to investigate how anxious and avoidant attachment are related to personality disorder (PD). Factor analysis showed that self-reported anxious attachment and 11 PD scales from the Dimensional Assessment of Personality Problems loaded onto one factor (emotional dysregulation), and avoidant attachment and four PD scales loaded onto a second factor (inhibitedness). Biometric models indicated that 40% of the variance in anxious attachment was heritable, and 63% of its association with corresponding PD dimensions was attributable to common genetic effects. Avoidant attachment was influenced by the shared environment instead of genes. Correlations between avoidance and corresponding PD dimensions were attributable to experiences in the nonshared environment that influenced both variables.
