The interrelationship between pregnancy-specific anxiety and general anxiety across pregnancy: a longitudinal study

Abstract Background: High levels of prenatal maternal anxiety – either pregnancy-specific anxiety or general anxiety – may have detrimental effects on both the mother and her child. It is currently unknown how these two different expressions of anxiety influence each other over time during pregnancy. Aims: This study aimed to describe the relationship between state, trait and pregnancy-specific anxiety levels across pregnancy. Methods: Longitudinal data from three data-waves of a large-scaled sample of nulliparous normal risk pregnant women were used to display associations over time by means of autoregressive and cross-lagged panel models. Results: Cross-lagged, cross-time pathways from pregnancy-specific anxiety to state as well as trait anxiety were positively significant, while vice versa the most consistent links were found from trait anxiety to pregnancy-specific anxiety. Conclusions: We conclude that pregnancy-specific anxiety and general anxiety appear to influence each other over time, resulting in heightened anxiety for some soon-to-be mothers.

Failing the Duck test: Reply to Barbaro, Boutwell, Barnes, and Shackelford (2017)

In this reply, we respond to the critique by Barbaro, Boutwell, Barnes, and Shackelford (2017) in regard to our recent meta-analysis of intergenerational transmission of attachment (Verhage et al., 2016). Barbaro et al. (2017) claim that the influence of shared environment on attachment decreases with age, whereas unique environmental and genetic influences increase, which they felt was disregarded in our meta-analysis. Their criticisms, we argue, are based on a misunderstanding of the core tenets of attachment theory. Barbaro et al. (2017) unify parent-offspring attachment, attachment representations, and romantic-pair attachment under the same conceptual and empirical umbrella, even though these constructs serve different behavioral systems. We show that excluding the incompatible twin data on pair bonding from their analysis undercuts their argument. Statements about the role of the shared environment in attachment beyond early childhood are highly uncertain at this point. Importantly, even if the role of the shared environment were to wane with age, its effects may still be causally important in later childhood or adult outcomes, as either an indirect factor or as a factor influencing earlier developmental outcomes.

Weakened Resilience in Parenting Self-Efficacy in Pregnant Women Who Were Abused in Childhood: An Experimental Test

This study tested experimentally whether the combination of a history of childhood abuse and confrontation with difficult infant temperament is associated with negative changes in parenting self-efficacy. First-time pregnant women (N = 243) participated in the Adult Attachment Interview, which was used to assess the occurrence of abuse by parents in childhood and unresolved representations, and completed a task asking them to respond to infant cries. Sixty of the 243 participants (25%) experienced childhood abuse, mostly physical or sexual. The task simulated infant temperamental difficulty by manipulating soothing success in order to reflect an easy-to-soothe (80% soothing success) and a difficult-to-soothe infant (20% soothing success). Both after baseline and after each of the two stimulus series women assessed their parenting self-efficacy. Women who reported childhood abuse did not differ from women who reported no childhood abuse in parenting self-efficacy at baseline or in response to the easy-to-soothe infant (relative to baseline), but decreased more in parenting self-efficacy following the difficult-to-soothe infant. Effects did not vary according to resolution of trauma. These findings suggest that in response to infant temperamental difficulty, women who experienced childhood abuse may more easily lose confidence in their parenting abilities, which underlines the importance of preparing at-risk women for the possible challenges that come along with parenthood.
