replicate results of previous studies in a mixed gender sample of
Egyptian outpatients.
Aim The aim of the current study was to examine the effective-
ness of DBT without drug replacement relative to treatment as
usual “TAU” in improving behavioral outcomes related to SUD and
BPD, and improving emotional regulation.
Methods Forty outpatients with co-morbid BPD and SUD in
Alexandria and Cairo were assigned for one year either to com-
prehensive DBT program (20 patients), or TAU defined as ongoing
outpatient psychotherapeutic treatment from referring center (20
patients). Patients were assessed at baseline and follow up assess-
ment at 4, 8, 12 and 16 months was done using Arabic version of
Difficulties in Emotion Regulation Scale (DERS), urine multidrug
screen and time line follow-back method for assessment of alcohol
and substance use history.
Results Following one year of treatment, DBT group showed sig-
nificantly lower doses of drugs used, DERS score, rates of hospital
admission, ER visits, suicidal attempts and episodes of NSSI. Also,
DBT patients showed markedly increased retention in treatment
and longer duration of total alcohol abstinence and other drugs of
abuse. Positive outcomes were maintained for four months post-
treatment.
Conclusion DBT demonstrated superior efficacy in comparison to
TAU for treatment of Egyptian patients suffering from co-morbid
borderline personality and substance use disorder across behav-
ioral domains of SUD, BPD and reduction hospital admission,
emergency room visits and DERS score.

time-standardized measures

Introduction Burnout and depression are ordinarily assessed
within different time frames. Burnout is most frequently assessed
on an annual or a monthly basis whereas depression is gener-
ally assessed over a one- or two-week period. This state of affairs
may have partly obscured the burnout-depression relationship in
past research and contributed to an underestimation of burnout-
depression overlap.
Objectives We investigated burnout-depression overlap using
time-standardized measures of the two constructs. We addition-
ally examined whether burnout and depression were differently
associatedwithwork-related effort and reward, occupational social
support, and intention to quit the job.
Methods We enrolled 257 Swiss schoolteachers (76% female;
mean age: 45). Burnout was assessed with the Shirom-Melamed
Burnout Measure and depression with a dedicated module of the
Patient Health Questionnaire. Work-related effort and rewardwere
measuredwith a short versionof the Effort-Reward Imbalance Scale
and occupational social support with a subscale of the Job Content
Questionnaire. Intention to quit the jobwas assessedwith 3 generic
items (e.g., “I plan on leaving my job within the next year”).
Results We observed a raw correlation of .82 and a disat-
tenuated correlation of .91 between burnout and depression.
Burnout’s dimensions (physical fatigue; cognitive weariness; emo-
tional exhaustion) did not correlate more strongly with each other
(mean r = .63) than with depression (mean r = .69). Burnout and
depression showed similar associationswith the job-related factors
under scrutiny.
Conclusions Burnout and depression may be empirically-
redundant constructs. Measurement artifacts probably contributed
to an underestimation of burnout-depression overlap in many
studies.

Introduction The concept of the Dark Triad (DT) consists of the
dimensions of Machiavellianism, narcissism, and psychopathy, and
has gained increased interest within the last 15 years for its predic-
tive power to explain success in the fields of economy, politics, and
professional sport. However, recent research suggests that the asso-
ciations between DT and behavior are not as uniform as expected.
Aims Investigating the associations between DT traits and vul-
nerable narcissism, mental toughness, sleep quality, and stress
perception.
Methods A total of 720 participants between 18 and 28 years took
part in the study. The sample consisted of military cadres in the US
(n = 238), Switzerland (n = 220), and of students from the university
of Basel (n = 262). Participants completed self-rating questionnaires
covering DT traits, mental toughness, vulnerable narcissism, sleep
quality, and perceived stress.
Results Irrespective of the sample, participants scoring high on
vulnerable narcissism also reported higher DT traits, lower men-
tal toughness, poor sleep quality, and higher scores on perceived
stress.
Conclusions The present pattern of results suggests a more fine-
grained association between DT traits and further behavior, calling
into question to what extent DT traits might be a predictor for
greater success in the fields of economy, politics or elite sports.
Specifically, vulnerable narcissism seems to be key for more
unfavourable behavior.
