Introduction
Results
The self-completed Leeds Assessment of
Neuropathic Symptoms and Signs (SLANSS) is used to identify pain of
neuropathic origin and has been validated
(Bennett, et al. 2005). This research was to
translate the S-LANSS from English to
Arabic for subsequent use in a survey of
chronic pain in Libya.
There were strong correlations between items
in the Arabic and English S-LANSS (table 1).
The Arabic version identified 6 participants
(46.2%) as having signs and symptoms of
neuropathic pain (i.e. scoring more than 12 on
total S-LANSS). The original English S-LANSS
identified 5 (38.5%) of these 6 participants.
Numerical Rating Pain Scale scores in English
and Arabic versions were correlated, IntraClass
Correlation, (r=0.883, p=0.000).

Methods
Five Arabic speaking health professionals fluent
in both languages independently translated the
S-LANSS into Arabic. A sequence of translation
and back-translation then followed to produce a
final version of the Arabic S-LANSS which was
then completed by 13 Libyan nationals living in
the UK who had experienced pain (age range 25

These 13 participants completed the original
English S-LANSS one week later. Test re-test
reliability was performed by correlating answers
of the Arabic and English questionnaires.

Discussion
The final Arabic version of S-LANSS is
reliable and linguistically valid to use in
Libyan population. A study of a large sample
in Libya is needed to confirm that this Arabic
version is suitable to be used by noneducated and older members of Libyan
Society.
