Abstract
BACKGROUND: Graduates’ job performance has become a matter that needs urgent attention.
This is because many stakeholders are increasingly becoming interested in understanding the
extent schools are able to produce output that meets the yearnings of society. Along these lines, we
examined the contributions of alcohol intake to the job performance of higher education graduates
while treating mental stress and psychotic experiences as mediators in the nexus.
MATERIALS AND METHODS: The study's population comprised all the graduates of higher education
institutions in Nigeria between 2015 and 2020. Data were collected from a virtual cross‑section of
3,862 graduates who self‑reported to have taken alcohol in the past. These participants responded
to an electronic questionnaire that was mailed to them. The scale content validity for clarity and
relevance were 0.90 and 0.88, respectively, while the Cronbach alpha reliability estimate of the
instrument is 0.86.
RESULTS: Amongst many others, key findings indicate that alcohol intake, mental stress and
psychotic experiences jointly made a significant negative contribution to the overall job performance of
graduates (R2 = 0.256, 95% confidence interval (CI) [0.23, 0.28], P = 0.00). Mental stress (B = −0.09, β
= −0.14, z = −4.45, 95%CI [−0.24, −0.05], P = 0.00) and psychotic experiences (B = −0.26, β = −0.43,
z = −8.07, 95%CI [−0.68, −0.16], P = 0.01) have significant negative contributions to graduates’ job
performance, respectively. Alcohol intake and mental stress jointly predict the psychotic experiences
of graduates (B = −0.26, β = −0.43, z = −8.07, 95%CI [−0.68, −0.16], P = 0.01). Alcohol intake has a
positive contribution to the mental stress of graduates (R2 = 0.797, 95%CI [0.77, 0.825], P = 0.01).
Mental stress and psychotic experiences jointly mediated the relationship between alcohol intake
and graduates’ job performance.
CONCLUSION: It was concluded that high intake of alcohol and high levels of mental stress and
psychotic experiences significantly reduce graduates’ job performance generally and in specific
aspects. Alcohol intake can increase graduates’ job performance to a small extent depending on
the amount consumed.
