A majority of Australian parents say they never monitor their children's social media accounts, but a new report has found teenagers are being contacted online daily by strangers.
The Australian Psychological Society (APS) interviewed more than 1,000 adults and teenagers to gauge their use of social media use.
Fifteen per cent of teens reported being contacted by strangers daily on Facebook alone.
And nearly 10 per cent reported that they actively communicated with, or responded to, strangers daily.
Yet 60 per cent of parents said they 'never' monitored their child's social media accounts and didn't know the passwords.
"Social media is an asset for teens," APS spokeswoman Dr Lyn O'Grady said.
"But they are less able to identify risks and more likely to act impulsively compared to adults, and need boundaries, rules and the guidance of parents to help them make good decisions — just as they do offline."
Adults and teens feeling pressure from social media
Both adults and children reported that they felt under pressure about how they look and how others react to their social media posts.
APS executive director Professor Lyn Littlefield said while social media had some benefits, it can have a negative impact on wellbeing.
"Be selective about who you involve in your online social networks, just as you would offline. The people you connect with should boost your wellbeing, not undermine it," she said.
Psychologists say teenagers are at particularly high risk.
"Three in five teens agreed that they felt validated when others 'liked' or 'retweeted' their posts. Close to half felt bad about themselves if no one responded in this way to their posts," the report found.
Almost 40 per cent of teens admitted to using tools such as filters to improve their appearance in photos.
Teens indulging in too much screen time
The survey found teens are spending up to 3.3 hours a day on social media, with adults clocking 2.6 hours a day on their phones.
Some teens check their favourite channels (Instagram and YouTube) as much as 50 times a day, with both adults and teens checking their phones as soon as they wake up and last thing before going to sleep.
Many adults also reported difficulties in disconnecting from social media.
Dr O'Grady said the survey found 54 per cent of adults were highly involved with their mobile phone.
"[A total of] 20.9 per cent have been bullied online, and 27 per cent argued with a stranger online," she said.
She said parents modelling healthy technology use was one of the most powerful ways they could guide their own children.
