Introduction Nigerian adolescents report various sleep disorders
metaphorically based on the local/native description of such disor-
ders. Hence, it is sometimes difficult for clinicians without a good
grasp of the nuance in their description to understand their pre-
sentation.
Aim To develop a culturally relevant (Nigerian) instrument for
assessing sleep disorders.
Methods One thousand two hundred and twenty-seven Nige-
rian Secondary School adolescents (634 males and 593 females)
between 12–19 years with mean age of 15.20 (SD = 1.5) were
administered a 44 item instrument developed following the DSM
(V), American Association of Sleep Medicine’s International Classi-
fication of Sleep Disorders (ICSD, 2005) criteria, and case reports of
sleep disorders. The data was subjected to a Principal Component
Analysis using Varimax rotation.
Result Ten factors instead of the original eleven factors suggested
by the authors emerged in the analysis and on closer examination
and in juxtaposition with cultural nuances, it was found the ten
factors were in line with what is generally reported by adolescents.
Sleep walking disorders and sleep related movement disorders
loaded in one factor labelled sleep movement disorders, while
items representing non restorative sleep experiences, sleep talk-
ing, sleep paralysis, sleep apnea, circadian rhythm sleep disorder,
narcolepsy, insomnia, sleep terror disorder and nightmare disorder
loaded on their individual factors. The SDINQ showed a Cronbach
Alpha of .916 and a good correlation with subscales of the School
Sleep Habits Survey (SSHS).
Conclusions The SDINQ has been found to be a valid and reliable
instrument for assessing the presence of sleep disorders among
adolescents in Nigeria.

Introduction Restless legs syndrome (RLS) is a sleep disorder
affecting a significant part of general population. Clinically RLS is
characterized by abnormal sensations of irresistible urge to move
legs, becoming worse at night, and frequently causing insom-
nia. Consequences of RLS include daytime dysfunction, depressed
mood, anxiety and decreased quality of life.
Objectives Determine prevalence of RLS in professional cyclists.
Aims The aim of this study was to examine the prevalence of RLS
in professional cyclists. According to our knowledge this is the first
research of RLS in professional cyclists.
Methods A total of 43 professional cyclists were asked to com-
plete 4-item questionnaire based on IRLSSG Diagnostic Criteria
for RLS. Data from questionnaire was compared to antropometric
measurements, epidemiologic data, age of starting trainings and
total years of professional performance.
Results The results indicated that prevalence of RLS in profes-
sional cyclists is 14% and is higher than expected in this age group.
We found statistically significant relationship between RLS and
age (P < 0,001) and years of experience as a professional cyclist
(P < 0,001). Results revealedno significant differences between gen-
ders
Conclusions RLS seems to be a common problem in professional
cyclists. It can affect sport performance. Future efforts to estimate
the influence of RLS on professional sport performance should be
considered.

Introduction To our knowledge there are no research about the
influence of self-criticism and self-compassion in the occurrence of
insomnia.
Objectives To study the association between self-criticism, self-
compassion and insomnia on university students; to explore
differences in these associations on two moments of student’s
lives–examination and no examination period.
Aims We anticipate that the stress and pressure of the examina-
tion period have an impact on student’s sleep and there are, also,
differences by age and gender.
Method Self-Criticism and Self-Reassurance Scale, Self-
Compassion Scale, Pre-Activation Sleep Scale, Insomnia
Assessment Scale and Anxiety and Depression and Stress Scales
were answered by 160 college students (M= 26.45, SD = 7.98;
range = 19–54 years) during an examination period and by 108
college students during a no examination period (M= 26.34;
SD = 0.43; range = 19–54 years).
Results In both periods (examination and no examination period)
older students (30–54 years) tended to bemore self-compassionate
and tolerant, such as less self-critical and punitive. During the
