What this trial studies

This study aims to validate the Single-item Sleep Quality Scale (SQS) for patients with spine disorders by translating it into German and Italian. The research will be conducted in two stages: first, the translation and cross-cultural adaptation of the SQS, followed by an evaluation of its validity, reproducibility, and responsiveness in assessing sleep quality among these patients. By utilizing this tool, healthcare providers can better understand the impact of sleep quality on patients suffering from back disorders. The study addresses a significant gap in the assessment of sleep quality in this population.

Who should consider this trial

Good fit: Ideal candidates for this study are German-speaking or Italian-speaking patients aged 14 and older with a diagnosis of spine pathology.

Not a fit: Patients who are pregnant, undergoing treatment for sleep disorders, or unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable and culturally adapted tool for assessing sleep quality in patients with spine disorders, leading to improved patient care.

How similar studies have performed: Other studies have successfully validated similar patient-reported outcome measures, indicating a promising approach for this validation effort.
