Psychotic disorders, as well
as psychotic-like experiences and substance use, have been found to be
associated. The main goal of the present study was to analyse the relationship
between psychoticlike experiences and substance use in college students.
The
simple comprised a total of 660 participants (M = 20.3 years, SD = 2.6). The
results showed that 96% of the sample reported some delusional experience,
while 20.3% reported at least one positive psychotic-like experience. Some
substance use was reported by 41.1% of the sample, differing in terms of
gender. Substance users reported more psychoticlike experiences than non-users,
especially in the positive dimension. Also, alcohol consumption predicted in most
cases extreme scores on measures of delusional ideation and psychotic
experiences.
The association between these two variables showed a differentiated pattern, with a stronger relationship between substance use and cognitive-perceptual psychotic-like experiences. To some extent, these findings support the dimensional models of the psychosis phenotype and contribute a better understanding of the links between psychoticlike experiences and substance use in young adults.

Future studies should further explore the role
of different risk factors for psychotic disorders and include models of the
gene-environment interaction.
