Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study parameters are: * Parenting behavior, including physiological response to infant stimuli (*handgrip task*), sensitivity (*quality of care*), involvement (*quantity of care*), and protection. We will examine the effects of the baby carrier on these parenting behaviors. * Activity in brain areas associated with parenting. We will examine the effects of the baby carrier intervention on activity in these areas in fathers during the processing of infant signals and brief video vignettes designed to elicit protective parenting. * Oxytocin, vasopressin, and estradiol levels will be assessed in saliva. Cortisol and testosterone will be assessed in both saliva and hair samples. Saliva samples are used to measure current hormonal levels. Hair samples provide information on hormone levels in past period: as human scalp hair grows approximately 1 cm per month, hormone concentrations in 1 cm hair reflect the mean exposure of 1 month. These assessments have all previously been approved by the METC and the CCMO (see document nr: NL54702.058.15 and tested in a pilot sample (P15.359, NL54702.058.15); see document nr. NL49069.000.14). These measures take place at the MRI facilities at the LUMC. | — |
