Elsewhere in the study, 41% of people said seeing a scene on TV or in a film encouraged them to to talk to their friends about a mental health issue, while 39% say it prompted them to open up to their parents.

Almost two-thirds of teenagers said content warnings about themes and issues coming up were important, adding that it helps them to protect their own mental health and make informed decisions about what they want to watch.

Anxiety, stress and depression were the three biggest mental health concerns for teens, according to the study, with 64% of teens saying they wanted warnings on film and TV shows that feature content surrounding them.

Body image, suicide and self-harm were also among the issues teenagers felt most concerned by.
