Introduction Psychoactive substance use (PSU) in patients with
schizophrenia can affect the course of the disease and causes
many side effects. There is no clear evidence whether cannabis
use can trigger the first episode of schizophrenia. The main causes
of cannabis use in patients with schizophrenia are also still not
defined.
Objectives Determine causes of PSU in cannabis users with
schizophrenia.
Aims The aim of this study was to find out the causes of PSU in
patients with schizophrenia.
Methods Thirty-five cannabis users with schizophrenia (28
males, 7 females) were asked to complete 15-item question-
naire about the reasons of psychoactive substance intake. Eighteen
of them used also stimulants. Additional information if PSU or
schizophrenia occurred first was also taken.
Results The results indicated that regardless of stimulants use
PSU occurred before schizophrenia in 83% of patients. Main rea-
sons of substance intake were: need for relaxation (86%) which
was more often in marihuana group (100%) than in marihuana
and stimulants group (73.7%) and this difference was statistically
significant (P = 0.049), curiosity (80%), self-regulation of well-being
(74%), shyness, need for altered states of consciousness, expectation
that psychoactive substances could help them in problem solving,
relationships and sleep disorders (49–54%).
Conclusions PSU usually occur before the first episode of
schizophrenia. Anxiety, curiosity and looking for unprofessional
help are the most common reasons. The results may indicate an
increased need of psychoeducation and social support in many
areas of life. Future research should be considered.

Introduction Impulsivity has been studied as underlying mech-
anism among addictive disorders such as alcohol use disorder.
Several authors have suggested that impulsivity is not a unitary
construct and consist of several subconstructs such as response
inhibition, risk taking.
Objectives This study conceptualized impulsivity as a multidi-
mensional construct and those subconstucts of impulsivity can
predict alcohol use differentially.
Aims Our aim was to identify the specific component of impul-
sivity that explained the greatest variance in heavy and problem
drinking among a sample of alcohol use disorder.
Methods Participants with alcohol use disorder (n = 170) com-
pleted a behavioral test battery comprising response inhibition
tasks (Stop signal task), the Balloon Analogue Risk Task (BART)
as measures of subconstruct of impulsivity. Participants also com-
pleted the UPPSP as a measure of general impulsivity.
Results In a multiple regression model, impulsivity measured by
UPPSP and risk-taking was identified as the measures that pre-
dicted alcohol use and problems.
Conclusions Results suggest that among patientswith alcohol use
disorder, a behavioral measure of risk-taking predicts alcohol con-
sumption and alcohol problems, even when individual differences
in trait impulsivity are statistically controlled. However, behavioral
measures of response inhibition do not predict unique variance in
alcohol use in patients with alcohol use disorders.

Problem-solving appraisal as
mediator, moderator and predictor of
smoking-abstinence effects

Introduction There are extensive investigations explaining smok-
ing abstinence effect, yet little is known about the cognitive and
metacognitive mechanisms that underlie the severity of smoking
abstinence effects. Several studies reported that that problem-
solving appraisal is associated with psychological maladaptive
behaviors, such as depression, anxiety.
Objectives Examining the role of problem-solving appraisal as
mediator, moderator and/or predictor of the severity of withdrawal
symptoms and probably relapse.
Aims Studying the role of problem-solving appraisal in the sever-
ity of smoking abstinence withdrawal symptoms.
Methods The present study utilized a two-group pretest and
posttest design to examine the mediating, moderating and pre-
dicting role of problem-appraisal of smoking-abstinence effects. A
total of 92 adult men smokers were administered the problem-
solving inventory (PSI-Ar) as well as several self-report measures
of most reported smoking abstinence effects (pre-test), and then
were asked to stop smoking for 48 h and administered again the
same measures except the PSI-Ar (post-test).
Results The results revealed that problem-solving appraisal acts
as a possible mediator and predictor but not moderator of the
severity of smoking-abstinence effects. The individuals with who
appraised themselves as ineffective problem solvers have shown
more sever abstinence effects i.e. somatization, depression, general
anxiety, panic, mood states, smoking urges, insomnia and habitual
sleep duration.
Conclusions Problem-solving appraisal plays a key role in sever-
ity of smoking-abstinence effects by means of mediating the
relationship between abstinence effects before and after smok-
ing abstinence. The findings are discussed in the context of future
research and possible intervention recommendations.
