DECENTERING AND EMOTION REGULATION IN CHILDREN 2
Abstract
Mindfulness-based interventions have become increasingly popular within both adult and
child populations because they can lead to improvements in mental health. However, the specific
mechanisms responsible for improvements are unclear. In the present study, we investigated the
possibility that decentering, a mindfulness-related mechanism of change, supports emotion
regulation. We also explored whether inhibitory control or metacognitive monitoring, could
explain the relationship between decentering and emotion regulation. We recruited ninety-seven
children as part of a larger study of mindfulness. They completed a questionnaire measure of
mindfulness, a computerized inhibitory control task, and two physiological tasks relating to
metacognitive monitoring. Parents completed a questionnaire measure of children’s emotion
regulation. We did not find a significant relationship between decentering and emotion
regulation, or evidence for either inhibitory control or metacognitive monitoring mediators.
These findings could reflect definitional and measurement limitations of our decentering and
emotion regulation measures. Further research on child decentering measures and alternative
mechanisms of change would improve our understanding of how mindfulness-based
interventions promote change in children’s mental health.

Mindfulness in Children: Exploring the Relationship Between Decentering and Emotion
Regulation
Mindfulness is a broad term used to describe numerous practices and characteristics. Its
applications have become increasingly widespread, ranging from use in mental health settings
(Dimidjian & Segal, 2015), to workplaces for improving job performance (Dane & Brummel,
2014), and use in schools to help build resilience and improve students’ learning (Sapthiang et
al., 2019). Though multiple definitions of mindfulness exist, creating ambiguity around its
components (Van Dam et al., 2018), there are two main components that appear to remain
consistent across definitions: present-moment awareness and non-judgmental attitude towards
experiences (Bishop et al., 2004). Present-moment awareness generally refers to actively
observing and paying attention to one’s thoughts, feelings, and experiences as they occur in the
moment. Non-judgment involves maintaining an open and accepting attitude towards one’s
experiences and feelings as they arise.
Many of the applications of mindfulness are rooted in mindfulness-based interventions
(MBIs) such as Mindfulness-based Stress Reduction, created to alleviate stress and pain through
practices such as meditation and yoga (Kabat-Zinn, 2003). These interventions generally aim to
improve people’s mindfulness skills, such as non-judgment and focused attention, and to help
them learn to apply these skills to health or mental health challenges (Shapero et al., 2018).
MBIs generally have positive effects on adult’s psychological health, including reducing anxiety
and depression symptoms (Hoffman et al., 2010). For youth and adolescents, MBIs can lead to
post-treatment reductions in anxiety symptoms, depression symptoms, and behavioral problems
(Dunning et al., 2019). MBIs also help adolescents and children navigate through various
negative stressors they may experience at home or in school (Perry-Parrish et al., 2016).
DECENTERING AND EMOTION REGULATION IN CHILDREN 4
However, meta-analyses examining the effects of MBIs with youth only show small
positive treatment effects (Klingbeil, 2017; Dunning et al., 2019). This suggests that while MBIs
can help improve the general well-being of youth, there is still progress to be made in terms of
the effectiveness of MBIs. Maximizing the effectiveness for youth is important because a
person’s mental well-being during their childhood and adolescent years impacts their
development into adulthood, especially if the person experiences a mental health disorder
(Sapthiang et al., 2019). One way to increase the effectiveness of MBIs is to identify and target
the individual mechanisms that contribute to change in MBI outcomes, which can help better
tailor future interventions.
A core mechanism of change in MBIs may be decentering, a mindfulness-related
construct (Hoge et al., 2015). Decentering is the shift from a subjective to objective perspective,
where negative thoughts and emotions are not seen as accurate reflections of self or reality but
rather as temporary mental events (Teasdale et al., 2002; Bhambhani & Cabral, 2016). In the
adult clinical literature, researchers have proposed that decentering increases one’s ability to
regulate one’s own emotions, which in turn helps with reducing distress and anxiety symptoms
(Shapiro et al., 2006; Garland et al., 2015). Emotion regulation is defined as the process of
modulating emotions in response to the environment, including how we experience and express
them (Roemer et al., 2015). A positive relationship between decentering and emotion regulation
exists among adults (Hayes-Skelton & Graham, 2013). Some evidence suggests that MBIs
increase emotion regulation in adults (Garland et al., 2015) and that decentering might serve as a
mechanism of change (Segal et al., 2019). However, the possibilities have not been tested during
childhood, a time when emotion regulation develops significantly, is a predictor of mental health,
and relates to positive social functioning (Hudson & Jacques, 2014). Exploring whether the
DECENTERING AND EMOTION REGULATION IN CHILDREN 5
relationship between decentering and emotion regulation also exists in children could help
maximize the benefits of MBIs when applied in settings with youth, thus increasing positive
downstream effects for children into adulthood.
To better understand the relationship between decentering and emotion regulation, we
must also further explore the processes that may contribute to this relationship. One such process
may be inhibitory control, the process of stopping inappropriate prepotent or automatic reactions
or emotions in favor of context-appropriate responses (Riggs et al., 2015; Lee & Chao, 2012).
Although the relationship between inhibitory control and decentering has not yet been tested in
children, inhibitory control positively correlates with both mindfulness (Oberle et al., 2012;
Riggs et al., 2015) and emotion regulation in youth (Hudson & Jacques, 2014; Kieras et al.,
2005). The positive relationships among inhibitory control, mindfulness, and emotion regulation
provide evidence to inform the possibility that inhibitory control might mediate the relationship
between decentering and emotion regulation.
Another potential process contributing to the relationship between decentering and
emotion regulation is metacognitive monitoring. This is the ability to internally monitor and be
aware of one’s cognitive processes across different situations (Destan et al., 2014).
Metacognitive monitoring, and metacognitive ability more generally, is related to decentering, as
decentering involves several interrelated metacognitive processes such as meta-awareness and
separation from internal experiences (Bernstein et al., 2019). More broadly, metacognitive ability
is also related to mindfulness because metacognitive knowledge, including the belief that our
experiences and mental events are temporary, is necessary to achieve a mindful state (Jankowski
& Holas 2014). Children also use metacognitive knowledge when regulating their emotions.
From as young as five years old, they use emotion regulation strategies that require
DECENTERING AND EMOTION REGULATION IN CHILDREN 6
metacognitive monitoring of their own emotions, such as pretending things are different and
learning to like a negative outcome (Davis et al., 2010). Although metacognitive monitoring
appears to be positively related to both mindfulness and emotion regulation, there is limited
research on the relationship between metacognitive monitoring and decentering with children.
The present study explored the relationship between decentering and emotion regulation
in children. Based on the positive relationship between decentering and emotion regulation in
adults (Garland et al., 2015), we hypothesized that children who are better able to decenter will
also show better emotion regulation ability. This study also explored the potential mediating
effects of children’s metacognitive monitoring and inhibitory control ability on the variables of
interest. We hypothesized that children’s inhibitory control ability would have a mediating effect
on the relationship between decentering and emotion regulation, as being able to stop one’s
prepotent reactions to emotions might help one’s ability to successfully decenter. Similarly, we
hypothesized that children’s metacognitive monitoring ability would have a mediating effect on
the relationship between decentering and emotion regulation, as being able to monitor one’s
emotions and feelings are a central part of being able to successfully decenter. The relationships
among decentering, emotion regulation, inhibitory control, and metacognitive monitoring (see
Figure 1) may further our understanding of the key mechanisms that future MBIs for children
should focus on to improve well-being.

Method
Participants
Ninety-seven 9-to-13-year-old children participated in this study (M = 11.66; SD = 1.12;
males = 55). Participants were recruited either through flyers or from a laboratory subject pool
comprised of residents in Boulder, Colorado and surrounding areas. Seventy-five participants
identified as White, 17 identified as Asian, and 19 participants did not report their race. All
participants were able to understand and communicate in English. Parental informed consent and
children’s assent were obtained prior to participation. All procedures were reviewed and
approved by the Institutional Review Board. Children could pick two prizes from a range of
small toys and parents were compensated monetarily for time and travel.
Procedure
The data used in this study were collected as part of a larger study, which included
additional questionnaires, computerized behavioral tasks, physiological tasks, and word games
(see Appendix for complete list of measures). Only the tasks and materials relevant to the present
study will be discussed below. All participants individually completed the tasks in the same
order during one two-hour long session. While each child participated, the child’s parent
independently completed several parent-report questionnaires.
During the testing session, participants completed the Mindfulness Inventory for Children
and Adolescents which was verbally administered by the experimenter and then the Stop-Signal
task. Next, participants had the option to take a short break and pick out a small prize. They then
completed the Breath Counting task and Heartbeat Detection task. At the end of the session, they
had the option to pick another prize while parents received compensation.

Measures
Decentering
The Mindfulness Inventory for Children and Adolescents (MICA; Briere, 2011) was
verbally administered by an experimenter to each participant. The questionnaire contains 25
items and uses a 5-point Likert scale (1 = “disagree a lot”; 5 = “agree a lot”). It has five
theoretical subscales: self-acceptance, present-centered awareness, equanimity, metacognitive
awareness, and acceptance of internal experience. The MICA has not been validated but is age-
appropriate for our sample and appears to be sensitive to short-term changes in mindfulness for
7-to-12-year-old children (Goodman, Madni, & Semple, 2017).
To create a decentering measure from the existing tasks in the larger study, we asked five
independent raters who had theoretical knowledge about decentering to identify specific
questionnaire items that best represented decentering from the overall pool of items across all
child self-report measures. Raters were asked to sort all items from every questionnaire used in
the larger study, namely the MICA, Mindful Attention Awareness Scale for Children (MAAS-C;
Benn, 2004), and Child and Adolescent Mindfulness Measure (CAMM; Greco, Baer, & Smith,
2011), according to which construct best represented each item. The constructs were decentering,
awareness, and non-judgment. Raters were given the option to pick none of the constructs. Both
awareness and non-judgment were included as construct options because they are among the
constructs that the questionnaires were originally intended to measure. All raters received the
same definition for each construct. We defined decentering as “separating one’s thoughts and
feelings from perceptions of self and reality”. Awareness was defined as “noticing internal and
external experiences in the present moment” (Brown and Ryan, 2003) and non-judgment as
“having a non-evaluative attitude towards one’s thoughts, feelings, and reactions” (Baer et al.,
DECENTERING AND EMOTION REGULATION IN CHILDREN 9
2008). To form our decentering measure, we included the four items that every rater rated as best
representing decentering (i.e. full consensus). All these items were from the MICA. We averaged
the scores across the four items to create a decentering score for each participant. Scores ranged
from one to five, where higher scores reflected higher decentering ability.
Emotion regulation
The Behavior Rating Inventory of Executive Function (BRIEF) (Gioia, Isquith, Guy, &
Kenworthy, 2013) is a parent self-report questionnaire that consists of eight clinical subscales.
We used participants’ percentile rank scores on the “emotional control” subscale to measure
emotion regulation. The subscale is made up of 10 statements that assessed how well parents
perceived their children as capable of appropriately modulating their emotional responses (Gioia
et al., 2013). Parents were asked to rate each statement, for example “overreacts to small
problems”, on a 3-point scale (1= “never”; 2= “sometimes”; 3= “often”) according to how often
their child displayed the emotional response described in each statement within the last six
months. Percentile scores ranged from one to 99, where lower percentile rank scores on this
subscale reflected higher levels of emotion regulation.
Metacognitive monitoring
The first task was the Breath Counting task (adapted from Levinson et al., 2014), which
aimed to measure how well participants could continuously monitor and count their breaths for
six minutes. Participants wore a respiration belt around their abdomen which tracked their
breathing throughout the six-minute task. They were instructed to count their breaths silently in
sets of nine while pressing specific buttons on a keyboard after each exhale. They were told to
press the down arrow key for the first eight breaths and the up arrow key for the ninth breath.
DECENTERING AND EMOTION REGULATION IN CHILDREN 10
Participants were also instructed to press the spacebar key if they made a mistake or wanted to
restart their count at any point.
A metacognitive monitoring index was derived from the Breath Counting task based on
error-monitoring accuracy. This accuracy was calculated as 1- 𝑢𝑛𝑐𝑎𝑢𝑔ℎ𝑡 𝑒𝑟𝑟𝑜𝑟𝑠
𝑡𝑜𝑡𝑎𝑙 𝑛𝑜. 𝑜𝑓 𝑠𝑒𝑡𝑠 and represented
the proportion of sets where participants were either accurate or self-caught their errors. A set
was accurate if there were eight down arrow presses before one up arrow press. A self-caught
error was any set in which a participant pressed the spacebar to reset a breath cycle. An uncaught
error was any set in which a participant pressed the up arrow key without having previously
pressed the down arrow key eight times. Metacognitive monitoring is required to identify
instances of mind-wandering and to know when to press the spacebar to refocus on the task (Fox
and Christoff, 2014). Scores on this index ranged from zero to one, whereby higher values
reflected higher metacognitive monitoring abilities, while a lower value reflected lower
metacognitive monitoring abilities.
In the Heartbeat Detection task (adapted from Eley et al., 2007), participants were asked
to count their heartbeats during three timed intervals (35 seconds, 25 seconds, and 45 seconds)
while wearing physiological sensors that measured their actual number of heartbeats on their
non-dominant hand. After each interval, participants were asked to report how many heartbeats
they counted and to provide a confidence rating, which was based on how confident participants
felt about counting their heartbeats. It was rated on a 5-point Likert scale (1= “Not at all
confident”; 5= “Very confident”). To measure metacognitive monitoring, we compared
participants’ actual number of heartbeats with their perceived counted heartbeats and confidence
rating. This was calculated as the absolute mean difference between participants’ percentage
DECENTERING AND EMOTION REGULATION IN CHILDREN 11
error (( |𝑎𝑐𝑡𝑢𝑎𝑙 ℎ𝑒𝑎𝑟𝑏𝑒𝑎𝑡𝑠−𝑐𝑜𝑢𝑛𝑡𝑒𝑑 ℎ𝑒𝑎𝑟𝑡𝑏𝑒𝑎𝑡𝑠|
𝑎𝑐𝑡𝑢𝑎𝑙 ℎ𝑒𝑎𝑟𝑡𝑏𝑒𝑎𝑡𝑠) × 100) and their confidence ratings. Difference scores
ranged from zero to one, with larger difference scores reflecting higher metacognitive ability.
Inhibitory control
We assessed participants’ inhibitory control using a Stop-Signal task (Chevalier et al.,
2014) that is frequently used to measure inhibitory control. In a child-adapted version of the task,
participants were instructed to act as an air traffic controller and land planes in clear weather but
stop planes from landing in stormy weather. In every task trial, an airplane would appear either
on the left or right side of the screen and participants were instructed to press the correct
corresponding button. However, in a small subset of those trials, a stop-signal cue (a lightning
bolt) appeared on the screen after a variable onset delay time. Children were instructed to not
press any buttons if the stop-signal cue appeared. Inhibitory control was measured using
participants’ mean Stop Signal Reaction Times (SSRTs). This reflected the time it took for
participants to inhibit the prepotent response of pressing a button. It was calculated using a
Bayesian Parametric approach that estimated participants’ distributions of SSRTs (Matzke et al.,
2013). Shorter mean SSRTs reflected higher inhibitory control ability.
Statistical Analyses
We used a bivariate linear regression model to investigate the relationship between
decentering and emotion regulation. We conducted several mediation analyses to test whether
inhibitory control and metacognitive monitoring mediated the relationship between decentering
and emotion regulation. For the metacognitive monitoring mediation model, we ran a Pearson
correlation between the scores from both metacognitive monitoring tasks, namely the Breath
Count task and Heartbeat Detection task, in the hopes of creating a more robust composite
measure. We planned to combine scores from both tasks if the scores were correlated. If they
DECENTERING AND EMOTION REGULATION IN CHILDREN 12
were not correlated, we planned to run two separate mediation models, one for each task. For all
of the models we tested, we removed potential outliers and found it did not change the
significance of any results.

Descriptive statistics for all variables are presented in Table 1. Missing or incomplete
data was not included in our analyses for each individual task (n = 1 for emotion regulation, n =
8 for Heartbeat Detection task, n = 2 for Stop-Signal task, and n = 10 for Breath Count task).

Does decentering predict emotion regulation?
Do inhibitory control and metacognitive monitoring mediate the relationship between
decentering and emotion regulation?
Although decentering was not statistically significantly associated with emotion
regulation, we tested our mediation model because an association between the two variables is
not a precondition for testing mediation effects (Hayes, 2017). There could still be significant
effects between the individual components of our models, such as the relationship between
decentering and inhibitory control or between inhibitory control and emotion regulation. Thus, it
was still informative to test these individual relationships. For instance, if we found a positive
relationship between inhibitory control and emotion regulation, it may suggest that future
interventions that target increased emotion regulation as an outcome should be centered around
enhancing people's inhibitory control.
Note. No significant relationship between decentering and emotion regulation, p=0.86. (Scores
have been transformed so that higher emotion regulation scores reflect higher emotion regulation
ability (100 - percentile score = transformed score).
DECENTERING AND EMOTION REGULATION IN CHILDREN 14
We predicted that inhibitory control would mediate the relationship between decentering
and emotion regulation. However, our findings did not support this mediation model (R2=-0.02,
p=0.75). The regression coefficient between decentering and inhibitory control was not
statistically significant (t(93)=-0.92, p=0.36). The coefficient between inhibitory control and
emotion regulation was also not statistically significant (t(91)=-0.75, p=0.45). The indirect effect
of decentering on emotion regulation, via inhibitory control, was not statistically significant ((-
8.48)*(-0.04)=0.34). Thus, decentering did not predict inhibitory control and inhibitory control
did not predict emotion regulation (see Supplemental Materials 1a and 1b for these bivariate
relationships).
To test the mediating effect of metacognitive monitoring on the relationship between
decentering and emotion regulation, we analyzed scores from the Breath Count task and
Heartbeat Detection task separately because scores from both tasks were not significantly
correlated with each other, r(80)=.04, p=0.69. The relationship between decentering and emotion
regulation was not mediated by participants' error monitoring accuracy in the Breath Count task
(R2=-0.01, p=0.67). The regression coefficient between decentering and error monitoring
accuracy was not statistically significant (t(85)=0.20, p=0.84). Similarly, the regression
coefficient between error monitoring accuracy and emotion regulation was not significant
(t(83)=-0.88, p=0.38). Based on the model using participants’ accuracy scores, the indirect effect
of decentering on emotion regulation, via metacognitive monitoring, was not statistically
significant ((0.007)*(-12.15)=-0.08). Metacognitive monitoring, as assessed via the Breath
Counting task, was not predicted by decentering and metacognitive monitoring did not predict
emotion regulation (see Supplemental Materials 2a and 2b for these bivariate relationships).
DECENTERING AND EMOTION REGULATION IN CHILDREN 15
Similarly, metacognitive monitoring as assessed via Heartbeat Detection difference
scores did not mediate the relationship between decentering and emotion regulation (R2=-0.02,
p=0.92). The regression coefficient between decentering and heartbeat difference scores was not
statistically significant (t(87)=0.36, p=0.72). The regression coefficient between heartbeat
difference scores and emotion regulation was also not significant (t(85)=0.34, p=0.73). When
accounting for participants’ difference scores, the indirect effect of decentering on emotion
regulation, via metacognitive monitoring, was not statistically significant ((0.009)*(5.97)=-0.05).
Metacognitive monitoring, as assessed via the Heartbeat Detection task, was not predicted by
decentering and metacognitive monitoring did not predict emotion regulation (see Supplemental
Materials 3a and 3b for these bivariate relationships).
Discussion
The study aimed to test the relationship between decentering and emotion regulation in
children. Specifically, we hypothesized that the higher the participants’ decentering scores, the
higher their emotion regulation scores would be. However, we found no significant relationship
between these two variables. We also predicted that both inhibitory control and metacognitive
monitoring would have a positive mediating effect on decentering and emotion regulation.
However, we found that neither variable had a significant mediating effect, suggesting that
neither inhibitory control nor metacognitive monitoring were related to either decentering or
emotion regulation.
For our main hypothesis, we found that there was no significant relationship between
decentering and emotion regulation. This is in contrast to prior work with adults, which found a
positive relationship between the two variables (Garland et al., 2015). Our finding demonstrated
that decentering was not a predictor of one’s emotion regulation ability. A possible explanation
DECENTERING AND EMOTION REGULATION IN CHILDREN 16
could be that decentering is not the mechanism responsible for change in emotion regulation.
Instead, there may be other constructs, such as increased levels of cognitive control (Joormann &
Gotlib, 2010), that could better explain changes in emotion regulation.
Another possible explanation relates to the complexity of measuring constructs such as
decentering among children. A limitation of our decentering measure could be how we defined
decentering, based on the wider literature. There were several apparent ambiguities across
decentering definitions. One example is the overlap between awareness and decentering.
Bernstein, Hadash, and Fresco (2019) define decentering as the “capacity to shift experiential
perspective” and suggest that meta-awareness is a process within decentering, thus making it
difficult to clearly distinguish awareness from decentering. Other researchers define decentering
as “shifting one’s perspective to observe life as a third-person observer” (Shapiro et al., 2006;
Bhambhani & Cabral, 2016). Additionally, it may be difficult to isolate non-judgment from
decentering, as decentering can be defined as “taking a nonjudgmental and accepting stance
towards thoughts and feelings...the capacity to take a detached view of one’s thoughts and
emotions” (Fresco et al., 2007). With these ambiguities in mind, we chose to focus on the
commonalities across definitions. It could be beneficial, however, for future research to
consolidate a central definition of decentering.
The way we measured decentering could have also limited our findings. None of the four
child mindfulness questionnaires in the larger study explicitly tested decentering. Also, we only
had a small number of raters who had some knowledge of decentering determine which
questions should be included. It could have been beneficial to consult with expert researchers
who have published work on decentering. Furthermore, because there is no existing decentering
measure for children, we only had an adult decentering measure (Experiences Questionnaire;
DECENTERING AND EMOTION REGULATION IN CHILDREN 17
Fresco et al., 2007) for us to compare to and model after. To resolve these limitations, it is
important for future decentering research to focus on creating a valid measure of decentering for
children.
Our measure of emotion regulation may have also contributed to the lack of significant
findings because it was a parent self-report measure and could have lacked sensitivity. Parents do
not witness all of their child’s behaviors and emotion regulation can occur internally, which
could lead to discrepancies between how they rated their child and how their child behaves
across different contexts. Additionally, parents may have unintentionally rated the frequency of
their child’s behaviors in a socially desirable way. A more valid measure of emotion regulation
might be a child self-report, such as the Emotion Regulation Questionnaire for Children and
Adolescents (Gullone & Taffe, 2011), or a child behavioral or physiological measure. Future
studies developing validated and child-appropriate measures of both emotion regulation and
decentering might be able to provide more insight into the relationship between the two
variables.
Contrary to our prediction, we found that inhibitory control was not related to either
decentering or emotion regulation. This finding suggests that decentering does not affect one’s
ability to stop prepotent reactions to one’s emotions. It also suggests that when children regulate
their emotions, they may not be tapping into their inhibitory control ability, specifically the
response inhibition measured through the Stop-Signal task. One explanation could be that both
decentering and emotion regulation may not require the total inhibition of an immediate emotion
and instead may require experiencing the emotion but not letting it have a negative effect on
oneself. However, more work is needed to tease apart this potential relationship. Additionally,
incorporating an emotion element, such as manipulation of emotion, into our measure of
DECENTERING AND EMOTION REGULATION IN CHILDREN 18
inhibitory control may be more effective for exploring the relationship between inhibitory
control and emotion regulation.
Similarly, contrary to our hypothesis, metacognitive monitoring was not significantly
related to either decentering or emotion regulation. While decentering may not be related to
monitoring ability, it is possible that decentering is related to other aspects of metacognition,
such as metacognitive control. This is the ability to control how cognitive processes will affect
one’s behavior in different situations (Destan et al., 2014). When it comes to decentering, the
importance may lie in one’s ability to actively control one’s actions in response to emotions,
rather than just being aware of one’s emotions. Likewise, with emotion regulation, being able to
appropriately control how one's emotions will affect oneself may be more important for
regulation than being able to monitor all the possible emotions one could have. Alternatively, it
could be the case that decentering and emotion regulation do not involve metacognitive
processes. While our findings were not significant, it does prompt further questions about the
underlying processes of decentering and emotion regulation.
The nature of our metacognitive monitoring measures may have led to the lack of
significant relationships between inhibitory control, decentering, and emotion regulation. Within
the broader construct of metacognitive monitoring, there exists more specific forms of
monitoring, such as performance monitoring. This involves monitoring and being aware of one’s
progress towards a goal and knowing when to change one’s behavior in order to attain the goal.
Both the Breath Count task and Heartbeat Detection task could be specifically measuring
performance monitoring. Thus, it may be that our tasks failed to capture the other aspects of
metacognitive monitoring that are necessary for both decentering and emotion regulation. Future
DECENTERING AND EMOTION REGULATION IN CHILDREN 19
studies testing all aspects of metacognitive monitoring are needed to resolve this measurement
limitation.
The characteristics and demographics of the study’s sample could also be a limitation.
Due to the limited recruitment areas and the unique demographics of the population in Boulder,
Colorado, it is hard to determine how generalizable our findings would be to the wider
population. Future studies would need to include a wider age range and a more heterogeneous
sample in order for findings to be generalizable to all children.
Despite the limitations of this study, it provides an important step in exploring the
relationship between decentering and emotion regulation and improving children’s well-being
more generally. This study suggests that decentering and emotion regulation are not significantly
related, but MBIs have still been shown to be beneficial for children’s well-being. There are
several other proposed mechanisms of change in MBIs such as acceptance or emotional
intelligence (Guendelman et al., 2017) that have yet to be empirically tested within child
populations. It may also be more advantageous to test the relationship between decentering and
emotion regulation in a treatment or intervention setting, where participants are actively
improving their decentering ability. Due to the self-report nature of our decentering measure, it
can be hard to determine participants’ true levels of decentering ability. We also found that both
inhibitory control and metacognitive monitoring had no mediating effect on the relationship
between decentering and emotion regulation, but it might be the case that there are other
mediators at play or that measurement limitations constrained our ability to test these
relationships. The field of research regarding MBIs and children is still developing and there are
numerous mechanisms of change to be explored.
