Background: Research indicates minors over 14-years have capacity, yet, in England and Wales, only over-16s are legally presumed able to consent. This study compared 14/15- and 16-year-olds’ decision-making about attending CAMHS. Method: Questionnaire-based study of 1129 14-16-year-olds. Results: Fewer 16-year-olds think parents contribute to decision-making. There were no significant differences between 14/15- and 16-year-olds in relation to thinking they have the final say, voluntariness or information preferences. Four-fifths wanted a range of information and thought it should be provided to all young people, not just those referred. Conclusions: 14/15-year-olds are as likely as 16-year-olds to be able to consent to attending CAMHS.
