Brief Summary

Stroke is a leading cause of adult disability worldwide, ranking as the third major cause of mortality in wealthy nations and the second in developing ones. When adapting a questionnaire for use in a different cultural context, a process called "cross-cultural adaptation" considers linguistic and cultural nuances. Guidelines outline the standard procedure to translate, assess psychometric properties, and culturally adapt questionnaires for new populations.

The Stroke Specific Quality of Life (SS-QOL), designed for self-administration, requires no training. Research indicates its accuracy in assessing stroke victims over the phone, with completion taking 10 to 15 minutes. Scores on the SS-QOL scale correlate with improved functioning. Internal consistency, measured by Cronbach's alpha, ranged from satisfactory to outstanding in stroke patients, indicating good reliability.

This study aims to fill a gap by translating the SS-QOL questionnaire into Urdu, facilitating culturally adapted assessments. Validating scores within the Pakistani population will establish the reliability and effectiveness of the Urdu version, addressing a literature gap in stroke-related quality of life assessments among Urdu speakers in Pakistan. This research aims to provide valuable insights and a comprehensive tool for clinical setups in diverse settings, urban or rural. Introducing a standardized gold standard test will enable healthcare professionals to confidently diagnose and prognose stroke patients. The SS-QOL questionnaire, with its 49 self-report items covering 12 energy-related domains, promises to enhance understanding of stroke's impact on the quality of life among Urdu speakers.

Detailed Description

A cross-sectional study was conducted on 147 stroke patients at the Physiotherapy Department of the University of Lahore Teaching Hospital, situated on Defense Road, Lahore. The study spanned nine months following the approval of the research synopsis. Participant selection utilized a non-probability convenient sampling technique. The inclusion criteria comprised stroke-diagnosed patients aged between 35 to 65 years, proficient in verbal Urdu communication. Patients with neurological conditions like Parkinson's disease, Alzheimer's disease, or dementia, as well as unconscious individuals, were excluded. Additionally, patients with musculoskeletal or orthopedic conditions potentially affecting upper and lower extremity functioning were also excluded.

Written informed consent was obtained from all patients, and approval was secured from the Ethics Committee of the University of Lahore. The translated Urdu version of the SS-QOL questionnaire underwent a four-step procedure. Initially, two native Urdu speakers independently translated the SS-QOL into Urdu, with one possessing medical expertise and the other from a non-medical background. Their translations were merged into a single version. This combined version was then translated back into English by two professional translators unfamiliar with the questionnaire and medical terminology to ensure consistent English translation.

A research committee, comprising physiotherapists, an orthopedic surgeon, translators, a language expert, and authors, held a meeting to assess all versions of the SS-QOL for alignment with Urdu cultural nuances and methodological accuracy. After methodological and grammatical analysis, a pre-final SS-QOL version was approved by the committee. Seventy patients confirmed their comprehension of the questions through pilot testing, and their feedback was deliberated upon by the authors. Subsequently, a final Urdu version of the SS-QOL was established.
