Aranda et al. Psychosocial factors and symptoms of stress in workers of a tire manufacturing company.
executives, nurses, secretaries and workers.
Benavides and cols (2002) refer to workers in the
construction, automobile, electrical, electronics and
multinational industries as a sensitive population, or
as Ansoleaga y Toro (2010) sees it, in which he nds
the vulnerable workers a mining company.
The large number of studies carried out by
teachers and health professionals is striking,
however, we agree with Moncada et al (2008) in
which he states that any salaried population may be
at risk and be sensitive to suffer its consequences.
However, the prevalence gures for the
psychosocial risks reported are reected in different
ways according to the activity in question and
the psychosocial risk that the worker perceives as
negative for him. Comparing the percentage (50%) of
the prevalence of psychosocial factors in the present
study, we can observe that this is high compared to
the 30% referred by the European Foundation (1996)
with the presence of factors such as when the worker
is exposed to work night, repetitive tasks, monotony,
working under constant pressure, excessive workload
and forced postures were the most frequent risks.
Similar data is expressed by the ILO (2001) where
it can be seen that since the 1980s workers were
orienting their work to be mentally very fatigued, to
having no opportunity to rest or to learn new things,
to the rhythms of work and the workloads were very
high, because they had no possibility of promotion,
because the relationship between their studies with
the job was not adequate.
On the other hand, Mireles, Pando and Aranda
(2003) using the scale of identication of psychosocial
factors of Legaspi, Martínez and Morales (1986) scale
similar to that of Silva, nd that, the areas of the work
system and social interaction were the most affected
(46% and 43%).
More recent research reports that the psychosocial
risks range from those who report being in third
place of importance approaching up to 80% of its
prevalence (Hernández, J.R, 2006) as those who
appreciate 37% (Enriquez et.al., 2010) or those who
report low capacity to make decisions and to deploy
their skills at work 48%, high psychological demands
47%, under social support of peers and superiors
41% and 67% imbalance between the efforts they
invest in work and the rewards they receive in return
(Ansoleaga, E., 2015).
The little signicant relationship seen in this
work can be compared with the study by Gómez,
Hernández and Méndez (2014), especially in regard
to the dimensions of "workplace conditions" and
"workload" since it is mentions, initially, that the
active work dimension and development possibilities
are in a high range of exposure, that the training they
require to perform the occupation are not adequate,
that there are high psychological demands and under
task control, that they feel that their work is not a
source of opportunities to develop their skills and
knowledge, that they feel unhappy with the physical
environment and space in the workplace, cleanliness,
hygiene and sanitation, temperature, ventilation
and lighting ; and that the results of association
reveal that there is a signicant and negative
relationship between risk factors, job satisfaction
and psychological demands.
The literature shows, in some cases, that there
is signicance between psychosocial factors and
mental health indicators, explaining that "the
more perception of work stress greater perception
of depression, anxiety, social dysfunction and
psychosomatic symptoms", but that this signicant
relationship it does not occur in all cases in terms
of indicators of working conditions refers to health
aspects (Gómez-Ortiz & Moreno, 2009), which can
not be compared with the results of this study since
here there was a signicant relationship between
being sick and dimensions of "work demands" and
"work role and career development". But, signicant
correlations between dissatisfaction with the work
role, work stress, negative relationships and little
social support with colleagues and superiors, negative
change in work pressure and workloads, with health
measures, are demonstrated by Matud, García and
Matud (2002).
As already stated, the presence of psychosocial
factors perceived as inadequate by the worker and for
him, constitute a risk of his own, and can even become
serious problems for his health. The manifestation
most known for exposure to psychosocial risks is
stress or, rather, distress (Aranda et.al., 2005),
that is, "the mechanism by which these risk factors
are associated with the emergence of diseases"
(Ansoleaga, Vezina, & Montano, 2014).
