The purpose of this study is to establish a cohort of pregnant women with severe mental disorder and to identify biological and psycho-social transmission mechanisms involved in the development of 'risk' and 'resilience' in the offspring. It is assumed that both 'resilient' and 'risk' development in offspring are caused by a complex interaction between multiple biological, psychological and social factors. The project focuses specifically on exploring the impact of physiological stress-sensitivity, attachment, care-giving and the familial and social context for care-giving. Previous studies support these factors as important for the development of these infants, but systematic research using a prospective design is needed to strengthen evidence and elucidate the importance of these factors in more detail. The interaction over time of physiological stress-sensitivity, attachment, care-giving and the familial and social context for care-giving are evaluated in terms of the evolution of very early indicators of developmental risk and resilience in infants with a known highly increased risk for developing a mental disorder.The findings of the study may potentially lead to more specific targets for preventive interventions, which can improve developmental outcome for these infants.

Infant attachment as measured by Strange Situation Procedure (Ainsworth et al. 1978)
Strange Situation Procedure is a structured observation. The infant is videotaped in a playroom during a series of eight structured 3-min episodes involving the baby, the mother, and a female stranger. During the observation the mother leaves and rejoins the infant twice, first leaving the infant with the female stranger, then leaving the infant alone to be rejoined by the stranger. The procedure is designed to be mildly stressful in order to increase the intensity of activation of the infant's attachment behavior. Videotapes are coded for four attachment classifications: secure, avoidant, ambivalent-resistant/dependent and disorganised.
Time frame: At infant 52 weeks of age
Infant neurobehavioral outcome as measured by Neonatal Intensive Care Unit Neurobehavioral Scale, NNNS, (Lester & Tronick, 2005)
NNNS is a 30-minute, 128-item assessment of neurologic, behavioural, and stress/abstinence signs that evaluates the full range of infant neurobehavior. It has 12 summary scales: habituation, attention, arousal, regulation, number of handling procedures, quality of movement, excitability, lethargy, number of non-optimal reflexes, number of asymmetric reflexes, hypertonicity, and hypotonicity and an additional stress/abstinence scale.
Time frame: 1-7 days and 4 weeks
Infant development as measured by Bayley's scales for infant development 3rd edition (BSID-III-R, Bayley, 2006)
The BSID III-R is a structured observation test assessing cognition, language and motor skills.
Time frame: 16 and 52 weeks of infant age
Infant stress exposure and physiological stress-sensitivity as measured by hair and salivary cortisol
Saliva samples are collected before and 20 and 40 minutes after NNNS (4 weeks), still-face procedure (16 weeks) and Strange Situation Procedure (52 weeks)
Time frame: 1-7 days (hair only) 4 (Saliva only), 16 and 52 weeks of infant age
Infant social-interactive behavior as measured by Coding Interactive Behavior, CIB (Ruth Feldman, 2012)
CIB is a global measure that looks at parent-child and dyadic affective states and interactive styles. Independent behavioral codes are aggregated into eight higher order constructs: The three child constructs are engagement involvement, withdrawal, and compliance; and the two dyadic constructs are dyadic reciprocity and dyadic negative states.
Time frame: 1-7 days, 4 and 16 weeks
