There are two articles that just came out about teen texting and parent/teen communication using texting. Overall, both articles say that texting does help communication. But the "hurt" comes with over or mis-use. Parents should discuss cell phone and texting guidelines, including the consequences and dangers (including predators who text and sexting ). Dangers aside, time spent online can be also important for teen development (via MacAuthur 2008 study) and is an evolving part of the way they communicate.
Common Sense Media published responsible text tips to help families set guidelines and many sites have summaries of texting lingo – so parents can teach their kids "texting ettiquette". Teens should have a strong knowledge of texting guidelines before they head to college, where there will be even more demand for texting and other forms of digital communications.
