This is also related to research by Mazzona  et 
al. (2009), which says that thalassemia children tend 
to experience high emotional temperament and poor 
socialization. Researchers argue that emotional 
symptoms in thalassemia children do tend to be 
more emotional, as evidenced by research showing 
an abnormal category of 74.4%, because sufferers 
feel different from others, and there are still people 
who think thalassemia is an infectious disease. 
Based on table 3 it was found that behaviour 
problems in children with thalassemia in Aceh are in 
an abnormal category (76.9%). It is on-going 
opposing behaviour without serious violations of 
social norms or the rights of others. This behaviour 
problem is a difficult problem often shown by 
children such as hitting, fighting, mocking, refusing 
to obey other people's requests (Istiqomah, 2017). 
According to Rescorla et al. (2007) as cited in 
Halimah, Allendekania, & Fajar T W (2016), the 
next behaviour change that occurs is the problem of 
decreasing attention. The risk of this problem is 
influenced by gender, ethnicity, and mother's 
education, adolescents with male sex increase the 
risk of decreasing attention. 
The results of the study found that many children 
had behavioral changes starting from facing down 
when the researcher invites to speak, and looks very 
nervous. This is in line with the research of Riyana, 
& Riza (2017) which says that thalassemia children 
experience behavioral disorders as much as 73.3%. 
Another study by Halimah, Allendekania, & 
Waluyanti (2016) says that adolescent boys with 
thalassemia have a higher risk of experiencing 
behavioral problems such as anxiety problems, 
social problems, and problems with less attention. 
Although, it does not rule out that behavioral 
problems could also occur in adolescent girls. Other 
factors that increase the risk of behavioral changes 
are the ethnicity, multi transfusion, maternal 
education, and the involvement of next of kin and 
relatives. 
Based on the table 3, peer relationships in 
thalassemia children is in the abnormal category 
(59.0%). Children are less able to socialize with 
their peers both at home and at school. The difficulty 
of children in socializing often makes children less 
accepted by their peers. This could limit the children 
in interacting actively within their peers (Istiqomah, 
2017). The results of the study found that many 
thalassemia children have poor relationships with 
their surroundings or peers. This is inherent with the 
research of Maghfiroh et al. (2014), who said that 
almost half of thalassemia children had low feelings 
of being accepted in a friendship environment. Thus, 
self-esteem is obtained from one self and social 
interaction with peers. Individuals will feel high 
self-esteem if they often experience success. 
However, there are influencing factors such as 
parents and peers that greatly affect the development 
of self-esteem. If children have good peers, they 
could increase their self-esteem. 
Researchers argue that the social environment 
has a relationship with peers. Therefore, the 
difficulty of socializing often makes children less 
accepted by their peers. This study showed an 
abnormal category of 59% for peer relation aspect of 
the children with thalassemia.  The most important 
thing about peer groups is to provide sources of 
information and comparisons about the world 
outside the family, peer interactions that have their 
peer to play a special role in socio emotional 
development. 
Researchers argue that many children tend to be 
more silent and unwilling to play; this is evidenced 
by the results of the study showing 84.6% abnormal 
categories in hyperactivity disorder. Although 
thalassemia children are not allowed to overact, 
nurses should provide counselling about child 
development, starting from motoric training and 
playing according to their age, but within limits they 
do not force children to play excessively. The 
researcher found that many thalassemia children 
who are not able to move much and prefer to be 
quiet, if they play only briefly but not too much 
because the child is easily weakened. This is in line 
with the research of  Fetriyah, et. Al (2016), which 
explains that most mothers regulate children's daily 
activities. This is so that rest and activity remain 
balanced, so that the mother gives direction to the 
child to rest because if you do too much activity and 
lack of rest will affect Haemoglobin levels in the 
blood and can affect health in general. 
The condition of children with thalassemia also 
affected the relationship with their families. It could 
potentially interfere with their welfare as individuals 
and disrupt their functioning socially. The research 
conducted by Indanah (2010), found that prosocial 
behaviour plays an important role in psychosocial 
support from family and peers. The family play a 
role by helping to control the behaviour of children 
facing physical and psychological changes. Indanah 
said only 59% of respondents reported getting peer 
support. Prosocial support and behaviour are mostly 
indicated by the involvement of friends in social 
activities that do not drain the child's energy. 
Researchers argue that there are still many children 
who lack of prosocial relationships with their peers. 
This is evidenced by the results of this study
