... For unwanted sexual solicitation (defined as requests to engage in sexual activities or sexual talk or give personal sexual information that is unwanted or, whether wanted or not, made by an adult), studies have shown prevalence rates from 5% to 36% (see, for instance, Baumgartner et al., 2010;Jones et al., 2012;Jonsson et al., 2019). One recent meta-analysis found that one in nine young people had experience of unwanted sexual solicitation (Madigan et al., 2018), whereas Livingstone and Smith (2014) found in their review of risks of cyberbullying, contact with strangers, sexting and pornography that less than one in five young people had reported such experiences. Surprisingly rates do not seem to be rising despite increased access to online technologies (Jones et al., 2012;Livingstone & Smith, 2014), although studies are not conclusive, definitions of online sexual abuse vary and little is known about the possible underreporting of abuse (Katz et al., 2021;Kloess et al., 2014). ...

... Random effects were tested to measure betweendyad variation in baseline difference scores (i.e., intercepts) and change in difference scores across time (i.e., slopes) across disorganized classification. The model was constructed upward from the null-model according to a priori blocked decisions, model fit testing (as per the log-likelihood ratio test), and reliability of random effects (Ludmer et al., 2017;Raudenbush & Bryk, 2002). The final model was estimated using restricted maximum likelihood and compared to the null model. ...

... On the other hand, potential moderators affecting the strength of the relationship between MCA and children's emotional and behavioural development have also been identified. These moderators include maternal mental health (Bouvette-Turcot et al., 2015;Isosavi et al., 2017;Miranda, de la Osa, Granero, & Ezpeleta, 2011), child biological characteristics (Bouvette-Turcot et al., 2015;van de Ven, van den Heuvel, Bhogal, Lewis, & Thomason, 2020;Villani et al., 2018), child sex (Linde-Krieger & Yates, 2018;Yoon et al., 2019) and parenting practices (Meller, Kuperman, McCullough, & Shaffer, 2016;Miranda et al., 2011). However, whether these mediators or moderators consistently play a significant role in the association between MCA and children's emotional and behavioural development remains to be established. ...

... As proposed by Bowlby [17][18][19][20], and further elaborated by more recent attachment theorists [21][22][23][24][25], the attachment relationship can influence psychological functioning and social relationships throughout the life cycle. A child's secure attachment has a positive impact on his/her later development and well-being; in contrast, an insecure attachment has a negative impact on his/her well-being, as widely demonstrated by research in this field [26][27][28][29]. Thanks to attachment studies, early child-caregiver interaction began to be investigated in experimental settings, paving the way for the advent of infant research which integrated psychoanalytic theory with attachment theory, developmental psychology, neuroscience and systemic theories [30][31][32]. ...

... Generally, there were 13 unique studies that examined relations between socioeconomic resources and child stress responses (Bernard et al., 2015;Bryson et al., 2019;Bush et al., 2011;Chryssanthopoulou et al., 2005;Koss et al., 2016;Liu et al., 2020;Ludmer et al., 2015;Lunkenheimer et al., 2018;Palmer et al., 2013;Saridjan et al., 2010;Vaghri et al., 2013;Zalewski et al., 2012Zalewski et al., , 2016 ...

... The cumulative risk model has been widely used in a variety of fields, such as depression, incomplete high school, tobacco use, arrest, physical disease (Atkinson et al., 2015), and health-related quality of life (Gonz A Lez-Cabrera et al., 2019). However, few studies have focused on the relationship between cumulative risk factors and addictive Internet use. ...
