“…The theory asserts that various forms of strain (e.g., life stress and negative social relationships) can cause stressful feelings and negative emotions and subsequently lead to deviant behaviors or addiction as a coping strategy or escape from the negative feelings ( Agnew & White, 1992 ). The theory was originally developed to explain delinquency and crime ( Agnew, 1992 ), and has been widely applied in various problematic behaviors, such as Internet addiction ( Jun & Choi, 2015 ), substance use ( Özbay, 2014 ; Sharp, Peck, & Hartsfield, 2012 ), problematic alcohol consumption ( Swatt, Gibson, & Piquero, 2007 ), disordered eating ( Piquero, Fox, Piquero, Capowich, & Mazerolle, 2010 ), aggression ( Zapolski, Banks, Lau, & Aalsma, 2018 ), cyberbullying ( Jang, Song, & Kim, 2014 ), and commercial sexual exploitation ( Reid & Piquero, 2016 ). Strain is a critical factor that causes individuals to conduct problematic behaviors ( Agnew, 1992 ).…”
