A set of fetal movements data in twins and singletons.
Description
This data was collected for research on the effects of maternal mental health on prenatal movements in twins and singletons (Reissland et al., 2021). There are two touch movement types of the fetus recorded: self-touch and twin-to-twin touch, and the mothers’ mental health status was collected on three variables: depression, perceived stress scale and stress. There are 14 pairs of twins, 11 of the mothers were available for one scan and 3 of them were available for two scans, i.e. in total there are 34 observations.
