“…However, the majority of them (60%) also used specific tools such as scales, tests, questionnaires, or interviews applied to the infants and/or parents. Specifically, the studies employed the following assessments to evaluate infants' signs: the “Behavioral State Instrument” (BSI) (Neal, ) (2), the “Brazelton Behavioural coding system” (Brazelton, ) (8) and the scales of behavioural states based on Als's research (Als, ; Als et al., ) (3; 8; 15; 20). Other tools were also used: the “Alarm Distress Baby Scale” (ADBB) (Guedeney & Fermanian, ) was used to assess socially interactive and socially withdrawn behaviours (27); the “Neurobehavioral Assessment of the Preterm Infant” (NAPI) (Korner & Thom, ) was used to evaluate infants' behavioural and neurological functioning (27); the “LATCH Breastfeeding Charting System” (Koyun, ) was employed to assess infant's sucking ability (18); the “Premature Infant Pain Profile” scale (PIPP) (Stevens, Johnston, Petryshen, & Taddio, ) or the “Bernese Pain Scale for Neonates” (BPSN) (Cignacco, Mueller, Hamers, & Gessler, ) were used to measure infants' pain (4; 5; 16); and the “Neonatal Therapeutic Intervention Scoring System” (NTISS) (Harrison, Johnston, & Loughnan, ) was employed to measure the severity of illness (27).…”
