Symptoms of attention-deficit/hyperactivity disorder (ADHD) are associated with significant impairments in adolescents’ academic functioning, as well as a lower level of education (Schmengler et al.,
2021). In selective educational systems like in the Netherlands, this association begins in childhood, when children with high levels of ADHD symptoms are more frequently assigned to lower educational tracks. Selective educational systems are defined by an early selection into different educational tracks while allowing for mobility between tracks post-selection. Subsequent to this initial selection, symptoms of ADHD have been consistently associated with moving to a lower educational track throughout all phases of adolescence and in young adulthood (Schmengler et al.,
2021).
While the association between ADHD symptoms and lower education is well-established, little research has focussed on risk or protective factors in the social context, which may contribute to this association (Dvorsky & Langberg,
2016; Dvorsky et al.,
2018; Zendarski et al.,
2017). This is surprising, considering that it is well known that adolescents with high levels of ADHD symptoms commonly experience problems in their relationships with parents, teachers, and peers (Ewe,
2019; Glatz et al.,
2011; McQuade,
2020). Meanwhile, studies have consistently highlighted the importance of these relationships for adolescents’ academic development in general (Lin et al.,
2019; Robertson & Reynolds,
2010; Roorda et al.,
2017; Tao et al.,
2022; Wentzel et al.,
2021). It is therefore plausible that poorer social relationships with parents, teachers, and peers might act as mechanisms (mediators) contributing to the association between ADHD symptoms and lower education. Furthermore, adolescents with relatively poor relationships with their family, peers, or teachers and high levels of ADHD symptoms may be at a particularly high risk of poor educational outcomes, which would imply interactions between ADHD symptoms and adolescents’ social context. From a clinical perspective, it is critical to explore these interactions to identify especially vulnerable subgroups, who should be prioritized for interventions.
A better understanding of social relationships in the context of ADHD and educational outcomes may also be informative for the development of new psychosocial interventions, as previous studies have highlighted the benefits of involving both the family and school to achieve positive outcomes (DuPaul et al.,
2020). For example, parent-teen behaviour therapy has yielded stronger reductions in ADHD symptom severity, as well as in impairments in organization, time management, and planning in the home setting than treatment as usual (Sibley et al.,
2016). A peer-delivered intervention prevented declines in class attendance, organization skills, and academic motivation throughout the school year in adolescents with symptoms of ADHD (Sibley et al.,
2020). Lastly, a strong student–teacher relationship was one of the most frequently endorsed facilitators by teachers for the use of behavioural classroom interventions for ADHD (Lawson et al.,
2022). In this study, we aimed to evaluate the role of three important family and school factors that could be targets in psychosocial interventions (i.e., family functioning, and social support by classmates and teachers) as mediators in the association between ADHD symptoms and (changes in) adolescent educational track in Dutch adolescents, whilst also taking into account potential interactions between ADHD symptoms and these family and school factors.
Family and School Factors as Mediators in the Association between ADHD Symptoms and Lower Educational Level
While the evidence for the direct and harmful effects of primary ADHD symptoms on adolescents’ education is strong (Schmengler et al.,
2021), ADHD symptoms might also affect educational outcomes indirectly, by causing impairments in aspects of adolescents’ social context important for their academic development, such as relationships with parents, teachers, and peers. Indeed, extensive research has characterized the harmful impact of ADHD symptoms on these relationships, which may lead to poorer family functioning and receiving less social support at school.
In the parental home, adolescents with high levels of ADHD symptoms frequently have difficulties following directions and are less responsive to cues and punishment, rendering parental rule-setting less effective (Glatz et al.,
2011). This can lead to perceptions of powerlessness in parents (Glatz et al.,
2011), who may react with less responsiveness and emotional support (Glatz et al.,
2011; Jones et al.,
2015). In families with adolescents with high levels of ADHD symptoms, studies reveal more parental stress, marital conflict, higher rates of divorce, as well as poorer overall family functioning (Moen et al.,
2014; Schroeder & Kelley,
2009; Theule et al.,
2010; Wiener et al.,
2016; Wymbs et al.,
2008).
The classroom context, which requires students to sit still and pay attention, can make ADHD symptoms particularly salient. In comparison to their typically developing peers, adolescents with high levels of ADHD symptoms show significantly shorter attentive states during class, more off-task behaviours, and less overall engagement in school (Rogers et al.,
2015). Often teachers lack awareness of ADHD, leading them to believe that students’ inattentive and impulsive behaviour is intentional (Wiener & Daniels,
2015), and they may hence resort to frequent criticism and disciplinary penalties, leading to further negative responses from adolescents (Honkasilta et al.,
2016). Indeed, studies report more conflictual and less emotionally close relationships between students with ADHD and their teachers (Ewe,
2019).
ADHD symptoms can also cause difficulties in relationships with peers. For example, adolescents with ADHD more often have problems waiting for their turn in give-and-take exchanges, often talk excessively, and more frequently interrupt others (McQuade,
2020). Restlessness and fidgeting may be misinterpreted as disinterest or impatience (McQuade,
2020). As a result of these disruptive behaviours, adolescents with ADHD symptoms tend to report fewer friends, and are more commonly rejected by their classmates (McQuade,
2020; Wiener & Daniels,
2015).
Impairments in the family life and in relationships with teachers and peers caused by ADHD symptoms may adversely affect academic performance, and in this way contribute to the association between ADHD symptoms and lower educational attainment. Past research has highlighted poor social relationships within the family and with teachers and peers as risk factors for academic problems and poor educational outcomes. These studies have mainly focussed on academic development in general, and not specifically in the context of ADHD. For example, it was found that adolescents from poorly functioning families tend to have lower math, logic, and reasoning skills (Lin et al.,
2019), lower school engagement and academic self-efficiency (Stubbs & Maynard,
2017), higher risks of school disruption (Sun et al.,
2021), lower academic achievement (Blackson,
1995), and ultimately lower educational attainment (Robertson & Reynolds,
2010; Roy et al.,
2017). The less effective parenting styles that frequently characterize poorly functioning families may act as a mechanisms connecting family dysfunction and poorer adolescent educational outcomes (Chan & Koo,
2010; Lin et al.,
2019; Matejevic et al.,
2014; Spera,
2005).
Accordingly, it was found that lack of social support by or poor relationships with teachers predict worse academic outcomes. Meta-analyses found associations of the quality of teacher-student relationships and social support from teachers with academic achievement (Roorda et al.,
2017; Tao et al.,
2022). Meta-analytic mediation analyses revealed that the association between social support from teachers and academic achievement was partially driven by behavioural (participation in academic activities, e.g., homework completion), emotional (feelings about school/academics, e.g., interest, enjoyment, school belonging and identification), and cognitive engagement (level of psychological investment in academics, e.g., intrinsic motivation, self-efficacy, self-regulation, learning strategies, goals and values) (Tao et al.,
2022). Also, social support by and the quality of relationships with peers have been associated with adolescents’ educational outcomes (Ahmed et al.,
2010; Fang et al.,
2020; Lorijn et al.,
2022; Wentzel et al.,
2021; Woodward & Fergusson,
2000). Adolescents who do not perceive much support from their peers tend to be less motivated to learn new skills, enjoy studying less, feel less competent and interested in subject-matter knowledge, and are less able to cope with academic difficulties, which in turn was found to predict lower academic achievement (Ahmed et al.,
2010; Fang et al.,
2020; Patrick et al.,
2007).
Regarding children and adolescents with high levels of ADHD symptoms, one study demonstrated that parental marital problems in childhood (which could be indicative of poor family functioning) are associated with lower educational attainment in young adults with a previous ADHD diagnosis (Roy et al.,
2017), and one study showed that not having a close bond with teachers is associated with lower academic motivation (Rogers et al.,
2015). While these two studies demonstrated associations between family and school factors and education amongst children and adolescents with ADHD, they did not assess whether these factors act as explanatory mechanisms in the association between ADHD symptoms and educational level. We aimed to address this omission by investigating whether having more ADHD symptoms contributes to poorer family functioning and less social support by teachers and classmates, and consequently a lower educational level (i.e., mediation).
Poor Family Functioning and Lack of Social Support by Teachers and Classmates may Amplify the Association between ADHD Symptoms and Lower Educational Level (i.e., Interaction)
Adverse family functioning and poor relationships with teachers and peers may also amplify the association between ADHD symptoms and lower education, yet past research on this topic is limited. We were able to identify only one study showing weaker associations between ADHD symptoms and lower Grade Point Average (GPA) in adolescents who felt socially accepted by peers (Dvorsky et al.,
2018). This suggests that adolescents with low social support by peers and high levels of ADHD symptoms may be at particularly high risk of poorer educational outcomes, as they, for instance, cannot rely on academic support from classmates, for example through sharing resources, such as notes and books, which may reduce the impact of their symptoms on education (Dvorsky et al.,
2018). To our knowledge, it has not yet been investigated whether the findings of Dvorsky et al. (
2018) concerning fluctuations in GPA extend to long-term outcomes, such as educational track membership. Furthermore, we are not aware of any studies that assessed interactions between family functioning or social support by teachers and ADHD symptoms in affecting adolescent’s educational level. It is conceivable that ADHD symptoms may affect educational level more strongly in the presence of poor family functioning, as poorly functioning families are less able to provide a supportive learning environment at home, for example by helping with homework, or vouch for their children at school. Similarly, ADHD symptoms may be particularly detrimental for the education of adolescents whose relationships with teachers are conflictual, given that adolescents with ADHD frequently have to rely on their teachers for accommodations to meet their academic needs (Harrison et al.,
2020).
