Stotts 2012.

Methods	Country: USA Setting: Neonatal Intensive Care Unit, Hospital RCT (3 groups)
Participants	Families with a smoker at home; infant in NICU at high respiratory risk
Interventions	Motivational interviewing. There were three groups; motivational interviewing, usual care, and usual care‐reduced measurement. The motivational interviewing group had 2 hospital‐based sessions of approximately 40 minutes each, 2 personalised letters, and 2 phone feedback sessions targeting infant ETS reduction. Reduced measurement group refers to reducing follow‐up, as this is thought to affect the behaviour of the control group.
Outcomes	Air nicotine monitors Infant end‐tidal carbon monoxide Self‐report measures of home and car smoking bans
Type of intervention	Child with health problems (respiratory disorders)
