Introduction

Smartphonesenteredthelivesofchildrenandadolescentsin2007.Comparedtoearlierdevices(flipphones),smartphonesallowedmorethanjusttextingandtakingphotos.Youngpeoplecouldnowbrowsetheinternet,choosefromthou-sandsofmobileapplications("apps")andgames,andconnectimmediatelywiththeircommunitiesthroughsocialplat-forms—fromanywhere.

Asinternetspeedsandcomputingpowerincreasedexponen-tiallyoverthepast15years,smartphoneshavebecomeevenmorepowerfulandversatile,allowinglivestreaming,multi-playergaming,andcreationanddistributionofcontent.Overarelativelyshortperiodoftime,thesehandheldcomputershavebecomeadisruptiveforceinthelivesofyoungpeople,inpositiveandnegativewaysthatadultswhogrewupwithland-linesmaynotfullygrasp.

Gettingasmartphoneisnowariteofpassageformostchil-drenandadolescentsintheUnitedStates.AccordingtoCommonSenseResearch,43%oftweens(age8to12)and88%to95%ofteens(age13to18)havetheirownsmartphone(Rideoutetal.,2022;Pew2022).AbouthalfofU.S.childrengettheirfirstsmartphonebyage11(Rideoutetal.,2022).Youngpeopledescribearangeofsupportiveandstressfulexperienceswiththeirsmartphones—somewishtheyhadn'tgottenonesoearly,whilealsodescribingitasanappendagethattheycannotlivewithout(Morenoetal.,2019).Thedeci-sionofwhentogetasmartphone,andnegotiationsaboutrulesandboundariesaroundsmartphoneuse,arefrequentsourcesofparentalstressandfamilyarguments(Mathesetal.,2021;Francisetal.,2021;Hiniker,Schoenebeck,&Kientz,2016).

Severalfactorscontributetoyoungpeople'sattachmenttotheirphones.First,itisdevelopmentallyappropriateforado-lescentstoseekconnectionandfeedbackfromtheirfriendsandcommunities,andtowanttodosoonafrequentbasis.Childrenandadolescentshavedevelopmentallyadaptivecuriosityaboutinformation,culture,entertainment,andstoriesthathelpthemmakesenseoftheirworld.
