Initial validation of the Behavioral Indicators of Infant Pain (BIIP)

Liisa Holsti, Ruth E. Grunau
2007 Pain  
The Behavioral Indicators of Infant Pain (BIIP) combines sleep/wake states, 5 facial actions and 2 hand actions.  ...  Since behavioral and physiological responses to pain in infants are often dissociated, using multidimensional scales which combine these indicators into a single score may limit our ability to determine  ...  Indeed, we retained 5 facial actions for use on the BIIP, including the 2 lower facial actions found to be valid for assessing post-operative pain in infants beyond the newborn period (Peters et al.,  ...
