The first 12.5 years of parenthood: A latent trait-state occasion model of the longitudinal association between maternal distress and child internalizing and externalizing problems.

Maternal anxiety and depression symptomatology are risk factors for the development of children's internalizing and externalizing behavior problems. However, it is still unclear whether chronic and transient symptoms relate differently to child behavior. The aim of this prospective longitudinal study (N = 193) was to investigate the associations between anxiety and depression symptomatology in a community sample across the first 12.5 years of parenthood, and children's internalizing and externalizing problems. Maternal anxiety and depression were measured at the child's age of 3, 6, and 12 months, and 2.5, 4, 6, 8, 10 and 12.5 years. At 12.5 years of age, both mothers and children reported on children's internalizing and externalizing problems. Trait-state occasion modeling was used to disentangle the chronic (trait) part of maternal symptomatology from the transient (occasion-specific) part. On average, 66.6% of the variance in maternal anxiety and depression symptomatology could be explained by the chronic trait factor. For both anxiety and depression, the chronic variance in maternal symptomatology was related to mother-reported internalizing, but not externalizing, problems of the child. Also, for child-reported internalizing problems, a significant association with maternal anxiety and depression symptomatology emerged. Only the occasion-specific part of maternal depression symptomatology at the child's age of 12.5 years was marginally related to mother-reported internalizing problems. Given that chronic subclinical symptomatology seems to be associated with child internalizing problems, prevention and treatment of maternal anxiety and depression symptomatology might be worthwhile regardless of the degree of severity.

A theory of social thermoregulation in human primates.

Beyond breathing, the regulation of body temperature-thermoregulation-is one of the most pressing concerns for many animals. A dysregulated body temperature has dire consequences for survival and development. Despite the high frequency of social thermoregulation occurring across many species, little is known about the role of social thermoregulation in human (social) psychological functioning. We outline a theory of social thermoregulation and reconsider earlier research on people's expectations of their social world (i.e., attachment) and their prediction of the social world. We provide support and outline a research agenda that includes consequences for individual variation in self-regulatory strategies and capabilities. In our paper, we discuss physiological, neural, and social processes surrounding thermoregulation. Emphasizing social thermoregulation in particular, we appeal to the economy of action principle and the hierarchical organization of human thermoregulatory systems. We close with future directions of a crucial aspect of human functioning: the social regulation of body temperature.
