Abstract 
The academic outcome is one of the essential factors affecting the 
comprehensive development of children. The present study examines the 
correlation between primary students’ behavior problems and their academic 
outcomes via the mediation role of classroom peer status in a cross-sectional 
study. Participants include 1855 Vietnamese primary students (Mage = 9.88, 
SD = 0.841 years). The strengths and difficulties questionnaire was used to 
measure students’ behavior problems. The students’ classroom peer status 
was measured by using homeroom teachers’ reports. Academic outcomes 
were collected using the school office reports about students’ academic scores 
in a whole school year. The results support two main findings: (a) students’ 
behavior problems has a direct effect on academic outcomes (effect = -0.167, 
p < .001, 95% CI [-0.210, -0.124]), and (b) the mediating role of classroom 
peer status in this model was significant (effect = -0.04, 95% CI [-0.055, 
-0.026]). The study’s results have shown that reducing behavior problems 
can help to improve primary students’ classroom peer status and academic 
outcomes. Based on the results, we suggest that implementing intervention 
programs for children with behavior problems and constructing a suitable 
educational environment focused on peer relationships will support children 
in improving their academic achievement.

TRUNG GIAN CHO MỐI QUAN HỆ GIỮA VẤN ĐỀ HÀNH VI 
VÀ KẾT QUẢ HỌC TẬP CỦA HỌC SINH TIỂU HỌC
Tóm tắt 
Kết quả học tập là một trong những yếu tố có ảnh hưởng quan trọng đến sự 
phát triển toàn diện của trẻ. Nghiên cứu hiện tại xem xét mối tương quan 
giữa các vấn đề về hành vi của học sinh tiểu học và kết quả học tập của các 
em thông qua vai trò trung gian của địa vị trong nhóm đồng đẳng tại lớp học 
trong một nghiên cứu cắt ngang. Đối tượng tham gia gồm 1.855 học sinh tiểu 
học Việt Nam (Tuổi trung bình = 9,88, SD = 0,841 tuổi). Bảng câu hỏi về điểm 
mạnh và khó khăn (SDQ) được sử dụng để đo lường các vấn đề về hành vi của 
học sinh. Địa vị đồng đẳng trong lớp của học sinh được đo lường bằng cách sử 
dụng báo cáo của giáo viên chủ nhiệm. Kết quả học tập được thu thập bằng 
cách sử dụng điểm tổng kết của học sinh trong cả năm học. Kết quả hỗ trợ hai 
phát hiện chính: (a) các vấn đề về hành vi của học sinh có ảnh hưởng trực tiếp 
đến kết quả học tập (effect = -0.167, p <.001, 95% CI [-0.210, -0.124]) và (b) 
vai trò trung gian của địa vị trong nhóm đồng đằng tại lớp học trong mô hình 
này đã xuất hiện (effect = -0.04, 95% CI [-0.055, -0.026]). Kết quả của nghiên 
cứu đã chỉ ra rằng việc giảm thiểu các vấn đề về hành vi có thể giúp cải thiện 
địa vị trong nhóm đồng đẳng tại lớp học, và từ đó nâng cao kết quả học tập 
của học sinh tiểu học. Dựa trên kết quả đạt được, chúng tôi đề xuất rằng việc 
thực hiện các chương trình can thiệp cho trẻ có vấn đề về hành vi và xây dựng 
một môi trường giáo dục phù hợp tập trung vào các mối quan hệ đồng đẳng sẽ 
hỗ trợ trẻ cải thiện thành tích học tập.

I. INTRODUCTION
The academic outcome was a familiar concept in education. The 
learning theory has been evolving for many years with varied definitions of 
learning (Illeris, 2018). Learning is a universal experience which endures 
throughout our lives. It is viewed as a source of personal and communal 
enrichment and an important component of the development of societies 
355
(Yardley et al., 2012). Lanchman (1997) defined learning outcomes or 
academic outcomes as the result of experiences that we acquire through 
learning. Academic achievement is important for children, obtaining good 
grades can improve their academic motivation (Hayat et al., 2020). It is 
also used to measure the quality of children’s life (Blair & Raver, 2012). 
According to the discussion above, academic outcomes significantly 
impact a child’s overall development, making it critical to explore further 
these factors.
Students’ behavior problems and their academic outcomes
Children with emotional issues can express their problems through 
behaviors such as hostility, defiance, destruction, disruption, impulsivity, 
overactivity, and aggressiveness (Campbell et al., 1996). These external 
behaviors have been shown to have a negative relationship with 
children’s learning capacity (Grusec, 1992). This relationship is reflected 
in the bioecological model of human development (Bronfenbrenner 
and Morris, 2006) which claims that individuals’ unique characteristics 
and experiences, including psychological and behavioral difficulties, 
can influence children’s developmental outcomes. A previous study 
of Mundy et al. (2017) suggested that students with conduct problems, 
hyperactivity/inattention, emotional issues, and peer problems have lower 
average reading scores than other peers. The children with difficulties also 
have a higher risk of having lower English and Maths skills (Mundy et 
al., 2017; Castro et al., 2020). Combining the research evidence above, we 
hypothesized that primary students’ behavior problems would influence 
their academic outcomes. 
Primary students’ classroom peer status as a mediator variable 
In Bronfenbrenner and Moris’s bioecological model of human 
development, individual characteristics (e.g., internal psychological, and 
behavioral) can influence friendship connections. On the other hand, the 
microsystem of peer relationships (including peer status) can contribute 
to a child’s academic success (Bronfenbrenner and Moris, 2006). Santrock 
(2018) illustrated peer status as a degree to which children’s peers like or 
loathe them. The peer status can have an impact on a child’s academic life 
356
as well as his/her mental health. Students’ behavior problems are linked to 
their lower level of peer status (Sturaro et al., 2011). Boys with proactive 
aggressiveness were associated with a negative relationship with peers 
(Useche et al., 2014). Children’s harsh and negative behaviors can predict 
their peer status in the future, they will have more risk of being rejected 
(Sturaro et al., 2011). 
Students’ classroom peer status, then, can influence their academic 
outcomes. Students with aggressive behavior, in particular, may have 
disadvantages in their social preferences as well as their academic 
performance (Risi et al., 2003). Peer rejection, marginalization, and 
victimization can lower children’s school engagement and sense of self-
competence which can affect children’s academic performance (Gou et 
al., 2018). Meanwhile, having a high peer status can assist a youngster 
in avoiding academic problems (Östberg, 2003). Based on the research 
evidence above, we hypothesized that students’ classroom peer status 
mediates the relationship between behavior problems and academic 
outcomes. 
The study’s research framework
The current study aimed to explore the relationship between students’ 
behavior problems and students’ academic outcomes, with classroom peer 
status as a mediator variable. First, we want to determine an association 
between students’ behavior problems, academic outcomes, and classroom 
peer status. Then we want to look at the mediation role of classroom 
peer status in the relationship between behavior problems and students’ 
academic outcomes. As a result, the current research hypotheses and 
model is as follows:
Hypothesis 1: Students’ behavior problems, classroom peer status, and 
academic outcomes are significantly and positively correlated. 
Hypothesis 2: Students’ behavior problems have a direct influence on 
academic outcomes. 
Hypothesis 3: Classroom peer status plays a mediatory role between 
students’ behavior problems and academic outcomes.

II. METHOD
2.1. Participants and procedures
The participants included 2297 students (age from 7 to 13, Mage = 9.88, 
SD = .841 years) in a local primary school at Ho Chi Minh City who 
sampled using convenience sampling. This research followed American 
Psychology Association (APA) ethical principles for psychology studies 
and was approved by Hoa Sen University’s Department of Psychology 
ethical committee for psychological research. Written informed consents 
were obtained from the school’s principal and students’ parents. Oral 
consent was obtained for students. 
The survey process had three different stages. First, the students 
completed the Strengths and Difficulties Questionnaire in 30 minutes at 
their classroom after being guided by trained researchers. Meanwhile, 
classroom peer status was collected from student’s homeroom teachers. 
Finally, the school’s office was contacted in order to receive the students’ 
academic outcomes using students’ academic grades. The final qualified 
and validated questionnaire was 1855. There were 922 (49.7%) girls 
and 933 (50.3%) boys, and 766 (41.3%), 602 (32.5%), and 487 (26.3%) 
corresponding to grades 3,4, and 5 respectively.

2.2. Measurements
Primary students’ behavior problems
The Strengths and Difficulties Questionnaire (SDQ) is usually used to 
evaluate students’ behavior problems (Goodman, 1998). This scale includes 
25 self-reported items and is divided into 5 subscales: Hyperactivity Scale, 
Emotional Symptoms Scale, Conduct Problems Scale, Peer Problems 
Scale, and Prosocial Scale. SDQ used Likert-3 points scale (0 = “Not True,” 
1 = “Somewhat True,” and 2 = “Certainly True”). The current study used 
the Vietnamese version which was translated and validated in previous 
studies (Dang., Nguyen., & Weiss, 2017). However, the prosocial 
behaviour scale was not employed. Four other sub-scales consisting of 20 
items were reported by the students. In our present study, the Cronbach’s 
alpha of the total scale was 0.633. In the present study, the CFA showed 
that the measurement model produced an acceptable fit at χ2/df = 2.966 
(p < .001), CFI = 0.900; TLI = 0.872; SRMR = 0.032; RMSEA = 0.032, and 
90%CI = [0.029, 0.036], indicating an acceptable construct validity.
Primary students’ classroom peer status
Students’ classroom peer status was measured by using the social 
distance measurement method (Bogardus, 1925). Bogardus’s scale was 
applied in this study to measure students’ social distance, and peer status 
also. A review form, including all students’ names, was sent to homeroom 
teachers to help them rate their students’ level of peer status. There is a 
guidance sentence in the heading of the review form that said: “Please rate 
your students’ classroom peer status according to the real situation in your 
classroom”. This questionnaire used Likert-9 points scale ranging from 1 
(meaning the homeroom teacher consider that the student has the lowest 
status in the classroom and has the least influence on other students) to 9 
(meaning the homeroom teacher consider that the student has the highest 
status in the classroom and has the most influence on other students). In 
the present study, the score ranged from 2 to 9.
Primary students’ academic outcomes
The students’ academic outcomes were obtained from the school 
office and were collected after students completed their final semester’s 
359
exam. The last academic year’s average result is the indicator of each 
student’s academic performance. Each grade has its criteria for a final 
score. It would be Math, Vietnamese, and Foreign Languages for grades 3; 
Math, Vietnamese, Foreign Languages, Science, History, and Geography 
for grades 4 and 5. The school office sent the researcher all the materials 
several weeks after the final exam took place. The average scores are in-
between 0 and 10.0, all the research work has been referred to by Circular 
22 of the Vietnam Ministry of Education and Training (MOET, 2016).
2.3. Data analysis
In the present study, we used the Statistical Package for Social Sciences 
(SPSS) 26.0 for managing data, descriptive analysis, and correlation 
analysis. At the same time, the Process macro v3.5, also designed by Hayes 
(2017), analyzes the relationship between primary students’ behavior 
problems and academic outcomes via students’ classroom peer status. 
Finally, simple mediation model 4 was used by researchers to develop the 
research framework (Hayes, 2017). 
III. RESULTS
3.1. Descriptive statistics of the variables 
Table 1 shows the descriptive statistics of Means, Standard Deviation, 
and Correlations between the variables. The data analysis showed that 
primary students’ behavior problems were significantly negatively 
correlated with both students’ classroom peer status and students’ academic 
outcomes. On the other hand, classroom peer status was significant 
positively with academic outcomes.

Testing for mediation model of students’ classroom peer status
First, the total effect of primary students’ behavior problems on 
students’ academic outcomes was analyzed using multiple linear regression 
(R = .207, R2 = .043, F = 83.570, β = -.207, t = -9.141, p < .001). Second, 
when classroom peer status was put into the model as a mediator variable, 
the direct effect of children’s behavior problems on academic outcomes 
was significantly negative (c’ = -.167, SE = .021, 95% CI [-.210, -.124]). 
Third, the Bootstrap confidence interval of 95% (sampling 5,000 times) 
was used to test the hypothesis, which is the mediating effect of classroom 
peer status in the relationship between children’s behavior problems and 
academic outcomes. The results showed that the mediating of classroom 
peer status in this model was significant negatively (a*b = -.04, SE = .007, 
95% CI [-.055, -.026]) (see Fig. 2).

IV. DISCUSSION
The direct effect of students’ behavior problems on academic 
achievement
The present study indicated that students’ behavior problems had 
a direct, significantly negative influence on academic achievement. 
The negative correlation between the two variables suggests that when 
361
students have more behavior problems will result in lower academic 
success. This finding aligns with previous research that has found a link 
between aggressive behavior, emotional issues, and academic achievement 
in students (Tamayo Martinez et al., 2021). In other words, behavior 
problems consume the students’ attention and motivation; therefore, time 
spent on essential learning tasks is diminished (Miles & Stipek, 2006). 
As a result, their academic outcomes have been reduced (Miles & Stipek, 
2006). The findings of this study combined with data from previous studies 
support the hypothesis that students’ behavior problems directly impact 
their academic achievement.
The mediating role of classroom peer status
This study showed that students’ behavior problems, classroom peer 
status, and academic achievement significantly correlate. The data analysis 
also supported the mediating role of classroom peer status on the direct 
pathway from students’ behavior problems to academic achievement. This 
mediating effect means that students’ behavior problems will decrease 
classroom peer status and negative classroom peer status, in turn, will 
affect their academic achievement. The present study results are consistent 
with previous findings showing that student behavior problems affect 
classroom peer status and ultimately reduce their academic achievement 
(Cillessen, 2020; Wang et al., 2018).
A previous study explained that disruptive, violent children and those 
who are socially nervous and withdrawn earn a disproportionate number of 
negative and few favorable nominations from their peers (Cillessen, 2020). 
Children who engage in aggressive conduct have a lower chance of being 
selected as friends than children who normally behave (Shin, 2017). This 
means that children’s behaviors strongly affect their peer status (Cillessen, 
2020). On the other hand, recent research has found that children 
rejected by classmates have a worse social adjustment ability, especially in 
academics (Prinstein et al., 2018). Students will achieve higher academic 
success if they are engaged by more peers (Wang et al., 2018). Disengaged 
students have a more challenging time dealing with school issues, which 
leads to a devaluation of their academic achievements and subsequent 
disengagement from school (Wang & Fredricks, 2014). Combining the 
362
above data analysis and research evidence supports our hypothesis that 
primary students’ classroom peer status mediates the relationship between 
behavior problems and their academic outcomes.
V. CONCLUSION
Our findings revealed two paths from conduct to academic success: 
one direct and one indirect. Behavior problems have a natural and indirect 
impact on academic performance through classroom peer status. This is 
one of the few Vietnamese studies to examine the link between behavior 
problems and academic achievement in primary school, as mediated 
by classroom peer status. Based on the study’s findings, we recommend 
that educators and school counselors boost effective intervention for 
children with behavior problems, and provide appropriate activities to 
promote students’ classroom peer relationships to enhance their academic 
achievement.
Of course, our current study contains some limitations. First, this is 
a cross-sectional study; the findings measured are those at the time, the 
ability to predict long-term results is restricted. It is impossible to establish 
a cause-and-effect relationship without longitudinal data. Second, due 
to self-reporting to measure the SDQ, common method bias may have 
a minor effect on data. Finally, because the current study focuses on 
elementary students in Ho Chi Minh city, we suggest that future research 
should investigate a variety of ages as well as other regions in Vietnam.
