Validation of the Bidimensional Resilience Scale for North American College Students
A Classification of the innate and acquired factors
July 2, 2014
Mari Hirano Graduate School of Education, The University of Tokyo
Introduction
My awareness of the issue
Can every individual learn
resilience equally?
How can people with low
resilience by nature
smoothly acquire resilience ?

Review of resilience from the viewpoints
of innateness Association temperament and inherited biological
bases in personality

Validation: twin method (Hirano, 2011)
Innate factors:
Correlation was seen among the MZ twins,
while the DZ twins did not show any correlation
Acquired factors:
Significant correlation was seen among both MZ
and DZ twins
MZ (41 pairs) DZ (15 pairs) difference in the ICC between
MZ and DZ ICC 95%CI ICC 95%CI

Validation: longitudinal research (Hirano, 2012)
The temporal stability was confirmed.
People who had experienced more positive life events
in achievement domains tended to have higher scores
on acquired factors.

Relationship between innate/acquired factors and
psychological sensitivity (Hirano, 2012b)
(Highly Sensitive Person; HSP; Aron, 1997)
psychologically
sensitive people had
low-innate factors.
In contrast, no relation
between sensitivity
and acquired factors. 0

Method
North American Students November, 2013
350 college students
Mean age=21.2 years (SD=2.58)
filled out online the BRS English version
.
Comparative data: Japanese Students October, 2008
433 university and college students
Mean age=20.7 years (SD=4.05)
administered during class time10
Result
The bidimensional structure was confirmed
(GFI=.900, AGFI=.873, RMSEA=.045)
High internal reliability
(total scale; α=.88, subscale; α=.82, .76)

North American students showed higher resilience
score compared with Japanese students.

Conclusions
A two-dimensional resilience scale (BRS) of strong
innate and strong acquired characteristics was
developed to design methods of heightening
acquired resilience.
The applicability of the BRS English version in
North American students was confirmed.

Subsequent discussion
Do they have only to learn ‘acquired factors’ ?
Acquired factors do not have an effect as
much as innate factors have. (Hirano, 2012)
How can people with low
resilience by nature
smoothly acquire resilience ?
