Infants’ symptoms of mental struggle are often diffuse and undifferentiated, and health services do not identify many infants at risk of poor development. However, primary health care is advantageous for early identification, given there are frequent consultations during the infant’s first two years. Health policy encourages using evidence-based screening but use varies in primary health care. The Alarm Distress Baby Scale (ADBB) is an assessment tool targeting social withdrawal in infants 2-24 months of age.

To explore contextual factors related to public health nurses’ (PHNs) acceptability of clinical assessment tools in a Norwegian child health centre.

Prior to an upcoming ADBB training, we used focus group discussions with PHNs to explore their views on their professional role and practice and how this concurs with using assessment tools.

Thematic analysis resulted in the following themes: (1) A Role requiring Supporting the Parents and Safeguarding the Infant; (2) The Challenge of Interpreting Infant Expressions; and (3) Organisational Preconditions for Accepting New Methods.

Our findings show that PHNs regard assessment tools as an aid to detect infants at risk, but that systematic use of such tools can hinder their ability to be flexible, egalitarian, and resource-focused. We also find that acceptability of assessment tools requires a system for continuous training and a well-established referral routine.
