The current study examined the effects of the "anti-monster letter" as a simple tool for reducing night-time fears in young children. One hundred and forty-two children aged 4 to 6 years were randomly assigned to either an experimental condition in which children and parents were provided with an "anti-monster letter" or a control condition in which no intervention was carried out. Results indicated that the "anti-monster letter" yielded positive effects. That is, child report data showed that night-time fears substantially decreased in the intervention condition as compared with the control condition. In parents, such positive effects could not be substantiated by standardised assessments, although some parents indicated that they considered the intervention as helpful.
