Validation of the Turkish Translation of the London Speech Evaluation Scale
Validation of the Turkish Translation of the London Speech Evaluation Scale
Purpose of the study is the validation and cultual adaptation of the Turkish translation of
 the London Speech Evaluation Scale (LSE-T), so that it would be used as an assessment tool
 for Turkish head and neck cancer patients. There is no validated Turkish version of LSE to
 measure severity of perceptual speech in head and neck cancer patients.
The speech function is a multidirectional process that depends on complex neuro-muscular
 network. The function can be evaluated using instrumental, such as voice analysis computer
 programmes, scales, or well structured questionnaires. There are many scales for assessment
 of perceptual speech but there is no validated for head and neck patients. The study will
 assess the construct validity and adaptation of the Turkish translation of Speech Specific
 Perceptual Speech Evaluation as known as London Speech Evaluation Scale. The investigators
 developed the Turkish translation of this scale (LSE-T), according to the cross-cultural
 adaptation guidelines. Two translators translated the LSE into Turkish and a native English
 language speaker reverse-translated it into English. The back translation was sent to the
 original author for proofreading. The LSE scale consisted of 6 parameters and 4 scores
 related with perceptual speech in head and neck cancer patients.
