Abstract
Objective
Executive function deficits (EFD) are a central mechanism underlying negative outcomes in ADHD. This study examined awareness of EFD manifested in “real-time” task performance (Online Awareness) and in general self-knowledge of daily activities, outside the context of a specific task (Intellectual Awareness) among adolescents with and without ADHD.
Methods
102 adolescents with (n = 52) and without (n = 50) ADHD were administered Weekly Calendar Planning Activity (WCPA) and Behavior Rating Inventory of Executive Function (BRIEF). Parents completed the BRIEF parent version. Awareness was defined using the discrepancy paradigm: performance versus estimation on WCPA for online awareness; self versus parent report on the BRIEF for intellectual awareness.
Results
Adolescents with ADHD overestimated their performance on the WCPA and underestimated their EFD on the BRIEF compared to parent’s ratings. The discrepancy scores in both types of awareness were significantly larger among ADHD than controls (p < .005).
Conclusions
Adolescents with ADHD demonstrate significantly lower rates of online and intellectual awareness of EFD compared to controls.

Introduction
ADHD is a highly prevalent neurodevelopmental disorder that persists through adolescence and adulthood (American Psychiatric Association (APA), 2013). The prevalence of ADHD in adolescence is estimated at 7% to 13% (Xu et al., 2018) and is associated with many functional impairments in everyday activities, challenges in social interactions, and academic underachievement (e.g., Biederman et al., 2011; Frazier et al., 2007). In the long term, adolescents diagnosed with ADHD are at risk for negative outcomes, including substance abuse (Molina et al., 2018), school dropout (Biederman et al., 2004), and driving violations (Barkley & Cox, 2007; Ratzon et al., 2017). Furthermore, adolescence has been described as a transitional developmental period, distinguished by a need for autonomy coupled with changes in physical, psychological, and social development (Esnaola et al., 2020; Weil et al., 2013), that may add more challenges to the day to day lives of this population.
Metacognition is defined as higher-level cognitive functions, including executive functions (EF) and awareness, which have been shown to significantly impact functional outcomes among individuals with developmental and acquired neurological health conditions (Katz & Maeir, 2011; O’Keeffe et al., 2007; Ownsworth & Clare, 2006; Toglia, 2018; Toglia & Maeir, 2018). Furthermore, metacognition is a foundation for ongoing self-management of a chronic neurocognitive health condition such as ADHD, which is the focus of the current study (Asherson et al., 2016; Turgay et al., 2012). The first component of metacognition is EF, defined as an interrelated set of higher-level neurocognitive abilities responsible for directing and coordinating goal-directed actions. EF comprises self-regulatory processes of cognition, emotions, and behaviors (Brown, 2013; Diamond, 2013; Miyake & Friedman, 2012; Zelazo, 2015). Executive Functions (EFs) help people mentally represent goals across time, anticipate future consequences of actions, and make behavioral adjustments when needed (Toglia & Katz, 2018). There is a strong relation between EF and ADHD, and many children, adolescents, and adults with ADHD exhibit EF deficits (EFD) that impact their functional performance and participation in life roles (Biederman et al., 2011; Brown, 2013; Silverstein et al., 2020). Adolescents with ADHD and EFD are the focus of the current study.
The second component of metacognition is awareness. This study is grounded in The Dynamic Comprehensive Model of Awareness (DCMA; Toglia & Kirk, 2000) which has been used to examine awareness among individuals with neurological health conditions such as acquired brain injury (Goverover et al., 2007), multiple sclerosis (Goverover et al., 2014), and recently also with ADHD (Kastner et al., in press; Levanon-Erez et al., 2019). The DCMA conceptualizes awareness as a dynamic interplay between the person and the context of the task. The individual is considered to develop two types of awareness as they interpret their occupational experiences over time: online awareness is situational and is influenced by the context of a specific task or situation. It includes both appraisal of task demands before a task and self-monitoring and self-regulation during and after the task. Thus, online awareness is usually assessed immediately before and/or after a specific task. Intellectual awareness (or general self-knowledge) exists outside the context of a specific task and encompasses the person’s perceptions, beliefs, and confidence regarding their everyday functioning, abilities, as well as challenges derived from a variety of health conditions. A dissociation between online awareness and intellectual awareness has been supported by research (Goverover et al., 2007; O’Keeffe et al., 2007; Robertson & Schmitter-Edgecombe, 2015). This distinction suggests that people may demonstrate good intellectual awareness in an interview yet poor online awareness within the context of an activity or vice versa.
The term metacognition is typically used in developmental literature (Flavell et al., 2001). However, other neuropsychology researchers conceptualized self-awareness as part of EF (Ardila, 2016; Lyzak, 1983; Stuss, 2011), suggesting that deficits in EF components may cause unawareness. Despite the different classifications of awareness, whether as a part of EF, or as a separate entity under the umbrella of metacognition, both intellectual and online awareness have been shown to significantly impact intervention outcomes and long-term self-management of chronic health conditions (Bodenheimer et al., 2002; Bussing et al., 2012; Toglia & Maeir, 2018). Individuals that understand their limitations, are more engaged in the intervention processes, and online awareness enables them to learn from their experiences and adapt their actions to support ongoing management of the challenges they face in daily life (Lyons & Zelazo, 2011).
Adolescents diagnosed with ADHD have been shown to have poor compliance with medications and psychosocial treatments (Khan & Aslani, 2019; Wehmeier et al., 2015). It is hypothesized that poor awareness of their challenges is an obstacle for engagement and persistence in the treatment process. There is some evidence for adolescents under-reporting of their ADHD symptoms and EFD (Steward et al., 2017; Volz-Sidiropoulou et al., 2016), a phenomenon known in the literature as a Positive Illusory Bias (PIB; Owens et al., 2007). Yet, others have shown that PIB is not universal and particularly only the social domain was stable (e.g., Bourchtein et al., 2017). Considering the centrality of EFD in the ADHD population, this study will focus on awareness of EFD from an ecological perspective, using measures that represent EF in “real-life.” The research on awareness of EFD among adolescents with ADHD is sparse. Only one study (n = 57) was found reporting significant differences between ADHD and controls regarding awareness of EFD, with a higher self-parent report discrepancy among adolescents with ADHD than controls (Steward et al., 2017).
There is a gap in the literature, regarding online and intellectual awareness of EFD among adolescents with and without ADHD. In order to evaluate online awareness, self-evaluation on performance-based cognitive-functional assessments that use simulated “real-life” tasks, have the potential to allow insights into individuals’ understanding of their daily performance (Wallisch et al., 2018). Furthering our understanding of awareness may be beneficial for designing effective cognitive-functional interventions for adolescents with ADHD.
The objectives of the present study are: (a) to examine online awareness of EFD on a performance-based cognitive-functional task, (b) to examine the intellectual awareness of EF in daily life using an ecological rating scale, and (c) to examine the reciprocal relations between the two types of awareness among adolescents with and without ADHD.
Method
Research Design
In this study, we used a cross-sectional design comparing two groups. Ethical approval for the study was obtained from the Helsinki ethics committee of the university medical center. Data were collected between the years 2016 and 2019. Both parents and adolescents signed informed consent. Participants in the ADHD group were recruited from neuropediatric clinics in the community and a tertiary care academic hospital. Participants in the control group were recruited through convenience sampling and snowballing techniques with age and gender matching to the research group.
Participants
The sample included 102 adolescents attending regular education schools, with (n = 52) and without ADHD (n = 50), between the ages of 12 and 18. Inclusion criteria for participants in the ADHD group were a valid ADHD diagnosis by neurologist or psychiatrist according to the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; APA, 2013) criteria confirmed by Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children—Present and Lifetime Version 2.0 (Kiddie-SADS-PL; Kaufman et al., 1996) administered by an expert psychologist, as well as stable pharmacological status during last 3 months. Exclusion criteria for the ADHD group included an estimated IQ below 85: Lower than one standard score on Block Design and Vocabulary subtests of Wechsler Intelligence Scale for Children IV (WISC-IV; Wechsler et al., 2004) as well as the use of medications that do not allow for 24-hour pause (e.g., atomoxetine). Exclusion criteria for the control group included ADHD symptomatology according to Conners’ Parent Scales-Revised (CPRS-R; Conner, 2000) based on scores above the cutoff for clinical impairment in both hyperactivity-impulsivity and inattentiveness DSM-IV symptoms subscales (T > 65) as well as learning disabilities (based on parent report). The CPRS-R was chosen as a screening tool only for the control group to evaluate the occurrence of non-diagnosed ADHD and common comorbidities, unlike the KIDDIE-SADS-PL that was used to validate the ADHD diagnosis and common comorbidities in the ADHD group. Another exclusion criterion for both groups was additional primary neurological or psychiatric health conditions based on parent report (e.g., Autism Spectrum Disorder, Cerebral Palsy, Epilepsy, Intellectual Disability). In order to represent the adolescent ADHD population, common ADHD comorbidity was not an exclusion criterion but evaluated according to Kiddie-SADS-PL and presented in the description of the study group.
No significant age and gender differences were found between the ADHD (n = 52) and control (n = 50) groups. Significant group differences were found in mother’s years of education, t(99) = 3.68, p < .001, whereby mothers of the ADHD group had more formal education. No significant associations (all p > .1) were found between this variable and all other study measures. Descriptive statistics of the ADHD group revealed that 63.5% of the participants took medication, 57.7% were diagnosed with the combined type of ADHD, and 58% had at least one comorbidity in addition to the ADHD diagnosis. Regarding potential confounds on awareness scores, no significant differences were found between participants who took medication for ADHD compared to those who did not, nor between participants who demonstrated only an ADHD diagnosis (pure ADHD) compared to those who had ADHD and additional comorbidities (all p > .1) (see Table 1).

Procedure
After receiving ethical approval, physicians and therapists referred adolescents with ADHD to the study. In addition, families responded to ads on social media. Control participants were selected from a pool of typical subjects recruited for a study of typical Israeli adolescents (n = 88) on the Weekly Calendar Planning Activity (WCPA). Subjects with CPRS-R ADHD symptoms above cutoff scores (n = 5) and parent report of learning difficulties (n = 11) were excluded. Fifty subjects were chosen to match the age and gender of the ADHD group. A phone call was made for potential participants who contacted an e-mail. The study was described to the parents who provided principle consent and then were invited with their adolescent to the university research laboratory. The ADHD group was also tested by the WISC-IV, and parents underwent the KIDDIE-SADS-PL interview by an expert psychologist. The study was coordinated by an experienced occupational therapist, PhD student (first author O.F.).
Measures
Weekly Calendar Planning Activity (WCPA; Toglia, 2015) is a performance-based EF assessment comprising a multi-step activity. The participant is presented with 18 randomly ordered appointments that need to be scheduled in an empty 1-week calendar. Five rules need to be followed: (1) leave Tuesday free, (2) do not cross out appointments after they are entered in the calendar, (3) ignore distracting questions from the examiner, (4) inform the examiner when it is a specified time, and (5) inform the examiner when finished. Decision-making, recognition of conflicts and strategies required to place the appointments in the most accurate space, are needed to minimize errors. The examiner observes and records the strategies used by the clients during the task and also conducts a semi-structured interview immediately after the task, probing awareness of performance and strategy use. WCPA is scored for accuracy (number of accurate appointments scheduled out of 18), number of appointments entered, planning time (time from the beginning of the assessment until the first appointment is scheduled), total time and efficiency score (accuracy/total time), error types, number of rules followed, and number of strategies used. A high level of inter-rater reliability (.99) for total accuracy score was established (Weiner et al., 2012), as well as moderate to high (.60–.85) test-retest reliabilities for performance measures (Lahav et al., 2018). Furthermore, discriminant validity between typical adolescents and youth-at-risk (Toglia & Berg, 2013) and between adolescents with epilepsy and controls were found (Zlotnik et al., 2020). Finally, discriminant validity between college students with and without ADHD on various performance measures was found (Lahav et al., 2018). Since the WCPA is a valid measure, representing EF performance in “real-life” and was tested on adolescents with neuro-cognitive challenges, as well as college students with ADHD, this measure was chosen to examine online awareness in the current study.
The Behavior Rating Inventory of Executive Function (BRIEF) Parent form (Gioia et al., 2000a) and BRIEF Self-Report (BRIEF-SR; Guy et al., 2004) is an ecological rating scale targeted to reflect the neuropsychological constructs of EF in daily life situations. Parent and SR forms are rated on a three-point Likert scale (“never,” “sometimes,” and “always”) based on child behavior over the past 6 months. The parent form is intended for parents of children and adolescents aged 5–18 years and comprises 86 items, whereas the self-report form encompasses 80 items and is intended for adolescents aged 12 to 18. Eight subscales are included: (a) inhibition, (b) shifting, (c) emotional control, (d) initiation, (e)working- memory, (f) planning, (g) organization of materials, and (h) monitoring. The BRIEF-SR includes one different subscale, “task completion,” that replaces the “initiation” scale. Scales are combined to form two indices—the Behavioral Regulation Index (BRI) and the Metacognition Index (MI), as well as an overall Global Executive Composite (GEC). The raw scores are transformed into T scores. The normative mean score is 50 (SD = 10). Atypical scores are indicated by T scores 65 or above, considered clinically impaired. Regarding the parent-report form, internal consistency (.80–.98), test-retest reliability (.79–.88), and discriminant validity have been established among children and adolescents individuals with ADHD (Gioia et al., 2000b; McCandless & O’Laughlin, 2007; Toplak et al., 2009). Regarding the self-report form, internal consistency (.72–.96), test-retest reliability (.59–.89), and inter-rater reliability (.36–.57) were established (Guy et al., 2004). Discriminant validity between adolescents with traumatic brain injury and healthy controls was found (Wilson et al., 2011). Recent studies compared BRIEF parent and self-report and levels of awareness abilities among healthy adolescents (Zlotnik & Toglia, 2018). In addition, unawareness was found among adolescents with ADHD using discrepancy scores (parent-self-report) compared to control group (Steward et al., 2017). For the purposes of the current study only the GEC score was chosen for statistical analysis.
Data Analysis
Awareness scores
Online awareness was operationally defined as the discrepancy between actual performance (accuracy score) and self-estimation after performance on the WCPA. Self-estimation was measured after finishing WCPA, while the researcher asked the participant: “eighteen appointments needed to be entered into the weekly calendar. Estimate the number of appointments that you entered accurately into the schedule” (Toglia, 2015, p. 142). These variables represented the same scale (0–18) and were derived from different times within the same subject, therefore, it is termed “Time effect.” Intellectual awareness was operationally defined as the discrepancy between adolescent self-report and parent report on the BRIEF-GEC, termed, “Reporter effect.” Mixed model ANOVA was computed whereby the within-subject factor was awareness (comparing performance versus estimation; “Time effect” or self and parent report; “Reporter effect”), and the between-subject factor was Group (ADHD vs. control).
Awareness categories
In addition to the continuous awareness scores, clinically meaningful categorical scores were calculated in order to evaluate the incidence in terms of unawareness in the study groups.
Awareness categories were calculated as follows: underestimation of performance (score −1), aware (score 0), and overestimation of performance (score 1) were computed based on 1.5 SD for each awareness score of the control group. Thus, for the online awareness, a discrepancy of 0–2.9 = “aware,” (−3) ≥ “underestimation,” and 3 ≥ “overestimation.” For the intellectual awareness, a discrepancy of 0–10.9 = ”aware,” (−11) ≥ “underestimation,” and 11 ≥ “overestimation.” Chi-square analysis was computed to compare awareness types (online and intellectual) between groups and to examine the association between online and intellectual awareness categories within groups. Significance was set at .05, and partial eta square (η2 p ) is reported as the effect size for the ANOVA test, with η2 p of .01 considered a small effect, η2 p of .06 considered a medium effect, and η2 p of .14 considered a large effect size (Richardson, 2011).
Results
Online awareness
There was a statistically significant interaction of Time × Group on the WCPA accuracy score [F(1,98) = 19.34, p < .001, η2 p = .17]. At time 1 (actual performance), the mean score of the ADHD group was lower than the control group, while at time 2 (estimation after performance), both groups estimated their performance as higher than time 1. The discrepancy between time 1 and 2 of ADHD group was significantly higher (Mean difference = −3.44, SD = 0.35, p < .001) than control group (mean difference = −1.26, SD = 0.35, p < .001) (see Table 2 and Figure 1).

Intellectual awareness
The interaction effect between Reporter (adolescent vs. parent) and Group (ADHD vs. controls) was significant [F(1,98) = 18.99, p < .001, η2 p = .17]. While in the ADHD group, parents reported higher BRIEF-GEC than their children, the parents in the control group reported lower BRIEF-GEC score as lower than their children. According to reporter 1 (parent), the mean score of the ADHD group was higher than the control group as well as reporter 2 (adolescent self-report). The discrepancy between reporter 1 and 2 of the ADHD group was significantly higher (mean difference = 7.08, SD = 10.03, p < .002) than in the control group (mean difference = −3.6, SD = 6.71, p = .004) that showed an opposite trend. In addition, differences between ADHD and controls were found on adolescent self-report (reporter 2), with the ADHD group reported significantly more EF impairment than controls [F(1,96) = 8.94, p < .001] (see Table 3 and Figure 2).

Associations/dissociations between online and intellectual awareness categories by group
Table 4 demonstrates a comparison of awareness categories (aware/underestimate performance/overestimate performance) between groups. Significant between-group differences were found for the online as well as intellectual awareness categories. Results show that in the ADHD group, 52% were aware of their online performance, while controls showed a higher rate of awareness, 78%. In the intellectual awareness categories, 54% were aware of their EF profile in daily life in the ADHD group, compared to 86% of controls.

Table 5 presents associations and dissociations between three categories of awareness in both measures (online and intellectual) within each group. In the ADHD group, results showed that while 31.3% were aware in both measures, 16.7% were unaware in both measures, 52% of the group demonstrate the dissociation between their online and intellectual awareness scores. The rates of association in the control group were higher, with 66% aware in both measures.

Discussion
The current study aimed to examine awareness of EFD manifested in “real-time” task performance (online awareness) and in overall daily life (intellectual awareness) among adolescents with and without ADHD. Results support the significant occurrence of unawareness phenomenon among adolescents with ADHD compared to their non-ADHD peers and, more precisely, their overestimation of EF abilities. This study also demonstrates a contextual aspect of awareness among adolescents with ADHD, comparing intellectual and online awareness showing the considerable incidence of both types co-occurring, yet also significant dissociations between them.
Findings of online awareness will first be discussed in relation to the entire sample addressing the developmental stage of adolescence in general, and then the specificity of findings regarding the study group with ADHD. The significant trend of overestimation of performance in both groups is consistent with other studies that used a similar performance-estimation paradigm. Within a developmental framework, comparing typical adolescents to college students (Bakracevic & Licardo, 2010) and adults (Demetriou & Bakracevic, 2009), significantly poorer awareness of performance on academic and cognitive tasks was found among adolescents compared to the older groups. Another study investigated the performance-estimation discrepancy on the WCPA accuracy score, as used in the current study, among typical adolescents (Zlotnik & Toglia, 2018). Their results demonstrated a significant association between performance and self-estimation. This phenomenon is known as the “Dunning-Kruger effect” (Kruger & Dunnung, 1999), showing a negative association between competence and self-estimation in the general population. In other words, the poorer the competence in a certain capacity, the larger the overestimation. This effect can also be applied to the current study, whereby one could posit that adolescents with ADHD who demonstrated poorer competence than controls on the WCPA also showed a higher performance-estimation discrepancy, as evident in the significant Time × Group interaction effect. However, additional research is needed to explore alternative hypotheses to the “Dunning-Kruger effect” such as deficit in a specific monitoring mechanism (Groom et al., 2010; O’Conell et al., 2009) as well as motivational processes (Hoza et al., 2012), which may explain the larger performance-estimation gap in the ADHD group. Regarding our findings related specifically to the ADHD group, our results are in line with several similar studies. Fabiano et al. (2018) investigated teenage drivers with ADHD in a simulated driving task and found that they overestimated their driving competence. In addition, Weiner et al. (2012) studied youth at risk who also demonstrate EF challenges. Their preliminary data pointed to a lack of awareness among these youth about the quality of their own performance after WCPA task completion. Taken together, there is a small but growing body of evidence supporting the claim that adolescents with ADHD may overestimate their performance on complex tasks more so than typical controls. These findings may shed more light on the negative functional outcomes identified in this population, such as driving risks (e.g., Barkley & cox, 2007), school dropouts (e.g., Biederman et al., 2004), substance abuse (e.g., Molina et al., 2018), and social problems (e.g., Bunford et al., 2018). Poor awareness of task performance could block a vital step in adaptive self-regulation of behavior toward self-serving goal achievement. Self- regulation encompasses both detection of errors and problems as well as adaptive regulating responses to these challenges (Vohs & Baumeister, 2016). If poor performance on complex daily tasks is not detected, then it can be assumed, similarly to populations with neurological injuries, that the impetus to learn and apply effective coping strategies or to engage in therapeutic processes will be lacking (O’Keeffe et al., 2007; Ownsworth & Clare, 2006; Toglia, 2018). Further research is needed to explore the mediating role of online awareness of complex daily tasks in predicting regulatory responses and functional outcomes among adolescents with ADHD.
The findings of the current study concerning intellectual awareness are also noteworthy. The significant interaction effect between reporter (adolescent/parent) and group, demonstrated a higher discrepancy (poorer awareness) in the ADHD group compared to controls. The vast majority of controls demonstrated intact general awareness (86%) of their EF profile in daily life, while the rest of the control participants showed underestimation compared to parent report. Thus, a general overestimation tendency in intellectual awareness, such as the one found in online performance, was not found. Controls were either aware of their EF in daily life or underestimated their abilities compared to their parents. On the other hand, within the ADHD group, one-third of the group showed an overestimation of their abilities compared to their parent’s report. These findings are consistent with previous research demonstrating PIB of overall EFD in daily life among adolescents with ADHD (Steward et al., 2017). The current study reinforces these findings, using the same measure and applied to a larger sample. Both studies examined adolescent populations using the parent and self-report discrepancy method on BRIEF scores. However, the first study examined 57 adolescents aged 11 to 16 (mean age—13.27), while the current study tested 102 teenagers aged 12 to 18 (mean age—14.6). Moreover, the first study investigated only intellectual awareness, while the current study examined two types of awareness as well as applying categorical analyses of awareness levels, using cutoff scores (aware, underestimation, and overestimation of EF). These findings add to other studies of intellectual awareness for other domains that found overestimation of functioning among children and adolescents with ADHD. Several studies compared the Self-Perceptions Profile for Children (Harter, 2012) with a parent or teacher report, focusing on social acceptance (e.g., McQuade et al., 2017), scholastic competence (e.g., Owens & Hoza, 2003), and behavioral problems (e.g., Hoza et al., 2004). Similarly, underestimation of ADHD symptom severity was also found on to the Conners Rating Scales (CRS; Weiner et al., 2012). The categorical methodology for both awareness types enabled a closer examination of the frequencies of awareness categories, revealing PIB in 30% of the sample regarding intellectual awareness and 50% for online awareness. These findings are in line with Fefer et al.’s (2018) results that illustrated the same percentiles of overestimation regarding academic and social competence. In the same vein, albeit slightly higher, half of the ADHD group demonstrated online over-estimation of WCPA performance. Taken together, these studies provide strong evidence for the presence of PIB for a variety of domains in ADHD. Nevertheless, results also demonstrate that unawareness is not universal for all participants with ADHD. Thus, when analyzing mean group tendencies, the extent of the unawareness phenomenon may be overestimated. Considering that EF is a central impairment in ADHD with far-reaching functional implications (Barkley, 2012), intellectual and online awareness of EFD may be an important target for improving treatment compliance and functional outcomes. Metacognitive interventions supporting the discovery of adolescents’ challenges before, during and after complex cognitive functional experiences, may be beneficial and warrant further study (Levanon-Erez et al., 2019).
Crosstabs analysis of awareness categories enabled comparisons between awareness types. The results showed overlap between awareness types among approximately half of the ADHD group, while the rest of the sample showed dissociations between awareness types. This complex picture is accordant with the DCMA (Toglia & Kirk, 2000), which differentiates the two types of awareness, yet also claims that there is a dynamic interplay between them. Cognitive developmental theories posit that monitoring and reflecting on experiences is a prerequisite for self-awareness (Flavell et al., 2001; Lyons & Zelazo, 2011). Intellectual awareness may develop from interpreting experiences (online awareness) over time, which could explain overlap. However, results also suggest that even in the face of intellectual awareness, online awareness may be restricted due to contextual factors such as task difficulty, environmental factors, and personal characteristics (Toglia & Kirk, 2000). Thus, despite the common co-occurrence between awareness types, it is equally common to find dissociations, highlighting the need to address both types in research and clinical practice. Further knowledge regarding the underlying mechanisms of both awareness types will facilitate understanding the relation between them.
Limitation and Recommendations for Future Research
There are some methodological aspects that need to be considered for further research. This study was conducted on a referred sample of adolescents with ADHD and a convenience sample of controls. The mother’s education level was relatively high and may not represent the general ADHD or typical population. Data did not include information on participants’ socioeconomic status (SES) beyond mother’s education. This is a limitation of the current study since SES may impact the ADHD population and EFD (Russell et al., 2016). Furthermore, the different methods for the exclusion criteria in both groups may confine the comparison between them.
In addition, the literature has suggested that there may be different awareness profiles for boys and girls diagnosed with ADHD in relation to online awareness (Jiang & Johanston, 2017) as well as intellectual awareness (Hoza et al., 2002; Tu et al., 2019). Age, comorbidities for ADHD, and medical treatment can also mediate or moderate the ADHD risk for unawareness. Although preliminary analyses revealed no medication or comorbidity effect on awareness variables, the sample was not sufficiently powered to examine these issues in depth. Thus, further research is needed to investigate the effects of these intervening variables on awareness of EFD, using larger and more representative samples.
Conclusions
Adolescents with ADHD demonstrate significantly lower rates of online and intellectual awareness of EFD compared to their peers. Substantial rates of dissociation between awareness types support the theoretical distinction between online and intellectual awareness, according to DCMA (Toglia & Kirk, 2000). Since unawareness is conceptualized as a barrier to adolescents’ engagement in treatment, further research is needed to discover underlying mechanisms of awareness.
