“…Furthermore, having a child prematurely "violates a mother's cognitive schema" (Greene et al, 2015, p. 369); the mental representation of what motherhood is expected to be is disrupted due to the truncating of the pregnancy and subsequent feelings of loss, grief, and anxiety (Woodward et al, 2014) associated with preterm birth. Low (<2,500g), very low (<1,500g), or extremely low (<1,000g) birth weight of the infant have been shown to affect parental development of mood and anxiety disorders in several studies (Al-Akour et al, 2014;Chang et al, 2016;Greene et al, 2015;Helle et al, 2016;Ukpong, 2011). Gestational age at birth correlates with an increase in PPD and anxiety symptoms in mothers of infants hospitalized in the NICU (Al-Akour et al, 2014;Chang et al, 2016;Kong et al, 2013;Misund et al, 2014;Ukpong, 2011); however, one study did not find significant correlations between infant gestational age and scores on the psychometric tools utilized to assess parent psychological functioning (Busse et al, 2013).…”
