Abstract: Losing the anatomy of the body will bring psychological pressure. For women, losing parts of the body that
have symbolic benefits such as breast will lead them to extreme emotional response. Mastectomy is one of
breast cancer treatment that makes a woman lose one or all of her breasts. This study was conducted to
examine the role of optimism in post-traumatic development in post-mastectomy women with subjective
well-being as a variable mediator. Instruments used in this study were post-traumatic growth questionnaires,
subjective well-being questionnaires, and optimistic questionnaires. Data were collected from 78 post-
mastectomy patients and chemotherapy or radiation therapy treatments. Regression Hayes Process statistical
techniques used to analyse data. Results showed that optimism provides subjective prediction and positive
relation direction with subjective well-being. Therefore, an increase of optimism will affect subjective well-
being to increase as well. Optimism also found to be significant in predicting post-traumatic growth.
However, subjective well-being may not necessarily directly increase post-traumatic growth of post-
mastectomy breast cancer patients.
1 INTRODUCTION
World Health Organization (WHO) noted that
cancer as one of leading cause of death worldwide,
especially to underprivileged and developing
countries. Data and Information Center Ministry of
Health Republic of Indonesia (2015) reported that
prevalence of cancer patients on all ages population
in Indonesia has reached 1,4% from approximately
254,9 million citizens as equal to 356,860 people.
Therefore, Minister of Health Republic of Indonesia
declared a Cancer Elimination Commitment in
Indonesia as coincided with World Cancer Day on
February 4th, 2015. The most common type in
Indonesian women is breast cancer and cervical
cancer. Jawa Pos (2017) found that on 2012-2015,
breast cancer patient in Public Local Hospital dr.
Soetomo Surabaya attained to 7,743 patients.
Managements on cancer patients consisted of
surgery, chemotherapy, radiation therapy, hormone
therapy, and immunology therapy (Cancer Council
Australia, 2016). There is various type of surgeries
on cancer, including mastectomy, which referred to
surgery on breast cancer patients to remove the
entire breast. Furthermore, Lismidiati, Setyowati,
and Afiyanti (2011) stated that the loss of specific
anatomy of body parts which has symbolic meaning
on women (e.g. breasts) would cause extreme
emotional response. This statement indeed supported
as post-surgery experience specifically to losing
certain body anatomy such as breasts on mastectomy
surgery on women could cause psychological
distress symptoms (e.g. anxiety, angry, confused,
depression) (Mirowsky and Ross, 2002; Lepperta,
Legrob and Kjerulff, 2007; Drapeau, Marchand and
Beaulieu-Prévost, 2012).
Post-mastectomy women would experience
uncomfortable feelings, stress, even trauma. Trauma
itself could be defined as post-traumatic stress
disorders (PTSD), which described as utmost
response towards heavy stressor, increased anxiety,
avoiding stimulus that associated to certain trauma,
dullness on emotional response, and symptoms
occurred for more than a month (Kring, Johnson,
Davison and Neale, 2012). On the other hand, there
were also women who managed to continue their life
and developed themselves in positive dispositions
after mastectomy and getting through medication.
Taylor (1998) and Wortan (2009) emphasized that
stressful event in life could brought changes to
positive experience as a result of struggle with
traumatic event. Moreover, Seligman and

Csikszmihalyi (2000) along with Tedeschi and
Calhoun (2004) explained that implementation of
individual resiliency concepts who experienced
trauma were known as post-traumatic growth.
Post-traumatic growth defined as positive
psychological changes which indicated by
relationship to others, new possibilities, personal
strength, spiritual change, and appreciation to life
(Tedeschi and Calhoun, 1996). These indicators
were most likely to occurred among post-
mastectomy women (Mahleda and Hartini, 2008;
Rahmah and Widuri, 2011; Rachmawati and
Halimah, 2015).
Furthermore, internal processes became the main
determinant to influenced and controlled process of
acquiring psychologically well-being (Compton,
2005; Snyder and Lopez, 2007). Studies on positive
mental health and positive psychology believe that
human has positive basic potential to guide them
reached balance in their life. In addition, this human
potential will help human survive in their life. To
conclude, current research aimed to explore internal
processes specifically optimism role towards post-
traumatic growth through subjective well-being as
mediator on post-mastectomy breast cancer patient.
2 METHODS
This current research was a survey study that used
questionnaire to collect data. Three instruments were
used in this study, namely post-traumatic growth
questionnaire, subjective well-being questionnaire,
and optimism questionnaire. Data were collected
from 78 post-mastectomy breast cancer patients and
went through chemotherapy medication (i.e.
radiation therapy).
Post-traumatic growth instrument used in current
research was adapted from Post-Traumatic Growth
Inventory (PTGI) by Tedeschi and Calhoun (1996).
PTGI consisted of five dimensions comprised of
relationship to others, new possibilities, personal
strength, spiritual change, and appreciation to life.
This instrument consisted of 21 items ( = 0,73).
Subjective well-being scale was composed by
researcher based on concept of subjective well-being
by Diener (1984). According to Diener (1984),
subjective well-being emphasized happiness on
cognitive and affection aspects. Well-being referred
to individual evaluation on their life, including
cognitive appraisal towards their life satisfaction and
affection appraisal to their mood and emotions.
Well-being itself could be seen from two dimensions
namely life satisfaction and occurrence of positive or
negative affect. This scale consisted of 10 items ( =
0,78).
Furthermore, optimism scale was adapted from
Life Orientation Test Revised Optimism Scale
(Scheider, et. al., 1994; Peterson, 2000). Optimism
described as individual response who has
expectations in the future. Optimistic person will
include efforts to overcome difficulties, attempted to
reach goals, and evaluated their expectation of
success. They also expect good things will happen in
the future. This scale consisted of 10 items ( =
0,83).\
Data were analyzed using Regression Process
Hayes statistical techniques with SPSS 2.0 Program
for Macintosh. Analysis was done using subjective
well-being variable as mediator in order to
illustrated participants’ post-traumatic growth on
every aspect of PTG itself. In conclusion, present
research hypothesized that optimism significantly
influenced post-traumatic growth among post-
mastectomy breast cancer patients that went through
chemotherapy medication or radiation therapy with
subjective well-being as mediator variable.

Optimism found to be significant in predicting
subjective well-being (b = 0,04; t = 1,32; p = 0,19;
R2 = 0,227) which accounted for 2% of the variation
in predicting subjective well-being. Moreover,
positive correlation also found between optimism
and subjective well-being which shown by b positive
value. Based on this correlation, the increase of
value optimism will be followed by the increase of
subjective well-being (Field, 2013).
Result of correlation between post-traumatic
growth to other variables (i.e. subjective well-being
and optimism) can be seen in Table 2. Based on the
results, optimism shown to be significantly
influenced to post-traumatic growth (p = 0,000; <
0,05), which indicated that optimism were able to
predict post-traumatic growth significantly while
including subjective well-being in analysis model. In
contrast, post-traumatic growth found to be
irrelevant in predicting subjective well-being (p =
0,837).
Table 3 provided total effect model on optimism
and post-traumatic growth mediation model.
According to Field (2013), total effect model
referred to predictor effect towards analysis results
by excluding mediator variable from the model (i.e.
correlation between optimism and post-traumatic
growth). Based on Table 3, it could be seen that
optimism was able to predict post-traumatic growth
notably (p = 0,000) by excluding subjective well-
being from the model. Moreover, this model
accounted for 88,3% to explained post-traumatic
growth. In addition, if subjective well-being
included to model, positive correlation was found
between optimism and post-traumatic growth (b =
2,284).
In addition to total effect model, indirect effects
also obtained from mediation results which
explained optimism variable and post-traumatic
growth (Table 4). Based on Table 4, indirect effects
of optimism to post-traumatic growth estimated in
0,003. Moreover, an accurate estimate of indirect
effects can be seen from b value (i.e. BootLLCI and
BootULCI values).

As stated by Field (2013), if b value on indirect
effects did not showed zero results then it could
indicate an occurrence of indirect correlation
between independent variable and dependent
variable. In other words, mediator variable could
mediate between these variables. As shown in Table
4, BootLLCI value and BootULCI value appeared at
-0,027 and 0,045 respectively, which means that
estimated value of indirect effect in this model lied
between -0,027 to 0,045. Since zero results appeared
within those range, it can be said that influenced of

optimism towards post-traumatic growth and
mediated by subjective well-being has unremarkable
figures.
In conclusion, current study showed that
subjective well-being insignificantly mediated
directly towards post-traumatic growth. Therefore,
subjective well-being was not necessarily increased
post-traumatic growth directly among breast cancer
post-mastectomy patients.
4 DISCUSSIONS
Person who diagnosed with cancer and required to
went through various therapy would experience
stressful period which could affect their
psychological aspects and social skills (Ho,
Rajandram, Chan, Samman, McGrath and Zwahlen,
2011). Furthermore, post-mastectomy patients and
were undergoing on medication (e.g. chemotherapy
or radiation therapy) tend to showed fluctuate
emotional changes. These progression of emotional
states could be referenced to concepts by Kubler
Ross (Santrock, 2015) which explained five stages
of grief to denial, anger, bargaining, depression, and
acceptance. Therefore, most of post-mastectomy and
undergoing medication patients would still be in first
several phase (i.e. denial, anger, and depression
phase) due to their experienced of sickness and
illness on pain they felt as consequence of
chemotherapy and radiation therapy. Moreover,
these sickness, illness, and pain would cause
anxiety, hopelessness, and insomnia (Hartini, 2004).
Eventually, post-mastectomy patients would
gradually enter bargaining and acceptance phase,
even it would take some time differently for each
patients. Once they reached to acceptance, patients
would be able to envisioned their future, decreased
their anxiety, hopelessness, and insomnia. These
phase could affect the ability to formed optimism
among patients to lived life after suffered such
illness. According to Ho, et. al. (2011), positive
coping strategy (e.g. hope and optimism) were
assumed to be significantly influenced individual
post-traumatic growth.
Self-acceptance and optimism among post-
mastectomy patients would induced positive
feelings, satisfaction against life experiences which
they have been through, along with increased in
positive affect while lowered in negative affect.
These psychological state reflected patients
subjective well-being. Moreover, it has been known
optimism that accompanied by social support would
take part as protective factors in preventing stress to
post-mastectomy patients (Applebaum, Stein, Lord-
Bessen and Pessin, 2014). Therefore, a high level of
optimism could reduce anxiety and depressive
symptoms. Other than that, optimism was known to
be able to improved better quality of life among
patients.
Study by Scheier and Carver (1985; 1992);
Scheier, et. al. (1999); and Schneider (2001) found
that optimism could resulted in both psychological
and physical healthiness. Optimistic person would
adopt healthy behavior to their life as an effort to
maintain their health state. While Kivimaki, et. al.
(2005) also stated that pessimistic and hopeless
individual would invested less effort to adopted
healthy lifestyle which resulted in rather negative
psychological and physical healthiness than positive.
Based on previous discussion above showed that
breast cancer patients could achieve post-traumatic
growth. As Wortman (2009) and Mahelda and
Hartini (2011) also supported those statement
describing two factors that were able to developed
post-traumatic growth namely cognitive processing
and disclosure. Furthermore, Rahmah and Widuri
(2011) stated that post-traumatic growth affected by
external and internal factors. External factors
referred to family support (e.g. husband, children,
grandchild, parents, and siblings) while internal
factors covered spirituality factors and reframing.
Optimism significantly impacted on subjective
well-being amongst post-mastectomy patients, as it
brought out positive response and expectations to
future. Optimistic patients would constantly put
effort to coped with difficulties and achieved
recovery. Moreover, internal process also known as
main determinant to affect and controlled the
process in acquiring subjective well-being.
Meanwhile, subjective well-being itself was
indirectly influenced post-traumatic growth.
Indicators of post-mastectomy patients who
managed to achieve post-traumatic growth were
individual that able to maintained harmonious
relationship to others, determined new possibilities,
acquiring personal strength, had a spiritual change
by devoting themselves to God, and capable to
appreciate their life.
There is however limitation to this research
regarding participants and control variable.
Insufficient number of participants in current
research has caused inability to generalized results in
this study. Additionally, researcher did not control
participants background criteria such as education
background and socioeconomic status.

5 CONCLUSIONS
Post-mastectomy women on undergoing medication
need optimism to recovered themselves. Optimism
were notably significant in predicting subjective
well-being, whereas increased optimism would be
followed by increased subjective well-being as well.
Likewise, optimism also significantly affected post-
traumatic growth, in which high level of optimism
could strengthened post-traumatic growth. In
conclusion, internal motivation to recovery and
social support would help patients through their
medication thoroughly.
