Exogenous testosterone increases status-seeking motivation in men with unstable low social status

Testosterone is associated with status-seeking behaviors such as competition, which may depend on whether one wins or loses status, but also on the stability of one's status. We examined (1) to what extent testosterone administration affects competition behavior in repeated social contests in men with high or low rank, and (2), whether this relationship is moderated by hierarchy stability, as predicted by the status instability hypothesis. Using a real effort-based design in healthy male participants (N = 173 males), we first found that testosterone (vs. placebo) increased motivation to compete for status, but only in individuals with an unstable low status. A second part of the experiment, tailored to directly compare stable with unstable hierarchies, indicated that exogenous testosterone again increased competitive motivation in individuals with a low unstable status, but decreased competition behavior in men with low stable status. Additionally, exogenous testosterone increased motivation in those with a stable high status. Further analysis suggested that these effects were moderated by individuals' trait dominance, and genetic differences assessed by the androgen receptor (CAG-repeat) and dopamine transporter (DAT1) polymorphisms. Our study provides evidence that testosterone specifically boosts status-related motivation when there is an opportunity to improve one's social status. The findings contribute to our understanding of testosterone's causal role in status-seeking motivation in competition behavior, and indicate that testosterone adaptively increases our drive for high status in a context-dependent manner. We discuss potential neurobiological pathways through which testosterone may attain these effects on behavior.

[Early childhood intervention - access to risk families and support through actors from the health-care sector]

Interdisciplinary cooperation and networking determine the success of activities for supporting families at risk for early childhood abuse. The integration of the healthcare sector might be important.The medical standard of perinatal care at the University hospital includes information exchange about family risk factors which may contribute to an increased risk of child abuse within the first year of life. As a result, the -pediatrician offered supporting services for the families at the time of the second examination during the official childhood health screening program (U2). A team of family-sponsorship was established and evaluated.In 281 of 1238 risk-factor questionnaires at least one stress factor was detected and 97 families had high-impact family stress. Families under the supervision of a family midwife or youth services had a significantly higher number of risk factors. The family-sponsorship program was institutionalized and positively evaluated by the families.The time of a hospital delivery is an excellent opportunity for the evaluation of familial risk factors and for the provision of supporting services. To increase the acceptance of such services by the families at risk repeated assessment of risk factors and support offers are required.
