tualización de la cognición social como rasgo
endofenotípico de la esquizofrenia, aunque se
requieren futuras investigaciones que amplíen
la muestra. No se observa relación entre funcio-
namiento psicosocial y cognición social, esto
puede deberse al tamaño de la muestra o al
tipo de instrumento utilizado para medir el fun-
cionamiento psicosocial.
Palabras clave:
Cognición social, teoría de
la mente, esquizofrenia, familiares de primer
grado, funcionamiento psicosocial, rasgo en-
dofenotípico.
Abstract
Objective: Analyzing whether social cogni-
tion is constituted as endophenotypic featu-
re of schizophrenia, appearing in siblings of
people diagnosed and remaining stable over
the course of the disorder . Study the rela-
tionship between deficits in social cognition
and psychosocial functioning. Method: The
sample consisted of patients diagnosed with
paranoid schizophrenia (29), siblings (14)
and controls (12). The performance of the
three groups in attributional style , social
perception, and emotional recognition (So-
cial Cognition Scale), theory of mind ( the
test of innuendo and Eyes test) was compa-
red. In addition, the group of patients was
evaluated in their psychosocial functioning
(HoNOS scale). Results: Patients scored sig-
nificantly worse than controls at all scales
of social cognition, except attributional
style. The siblings showed worse performan-
ce than controls in all scales of social cog-
nition except social perception and hinting
task. The patients scored worse than they
first degree relatives in social perception
and theory of mind, in other variables, si-
blings and patients showed no significant
differences. No significant correlation was
found between time since diagnosis and so-
cial cognition. Neither correlation is found
between any variable social cognition and
psychosocial functioning in the group of
people with schizophrenia. Conclusion: The
results show the brothers with moderate de-
ficit in social cognition, closer to patients
than to general population, supporting the
hypothesis of social cognition as a featu-
re appearing in high-risk states. It is not
found a significant relationship between de-
ficits in social cognition and time course of
the disease, according to the conception of
stable trait over time. Both findings support
the conceptualization of social cognition
as endophenotypic feature of schizophre-
nia, although further research to expand
the sample is required. No significant rela-
tionship between psychosocial functioning
and schizophrenia is observed, it could be
because of the sample size or the type of
instrument used to measure psychosocial
functioning.
