Cross-cultural Adaptation and Multicenter Validation of the Italian Versions of the Brief Evaluation of Receptive Aphasia (BERA) and SWallowing Assessment in Disorders of Consciousness (SWADOC)

14 июля 2026 г. обновлено: Alfonso Magliacano

Adattamento Trans-culturale e Validazione Multicentrica Della Versione Italiana Delle Scale Brief Evaluation of Receptive Aphasia (BERA) e SWallowing Assessment in Disorders of Consciousness (SWADOC)

Patients with severe acquired brain injury may evolve from coma into prolonged disorders of consciousness. In these patients, residual language comprehension and swallowing abilities are difficult to evaluate because standard assessments often depend on verbal or motor responses. The Brief Evaluation of Receptive Aphasia (BERA) assesses receptive language abilities through visual/eye-movement responses, whereas the SWallowing Assessment in Disorders of Consciousness (SWADOC) assesses oral and pharyngeal components of swallowing in patients with disorders of consciousness. This national multicenter observational study aims to perform the Italian cross-cultural adaptation and validation of BERA and SWADOC. Consecutive adult inpatients with severe acquired brain injury and disorders of consciousness will be recruited from four Italian centers. SWADOC will be administered to 57 patients, and BERA will be administered to a nested subgroup of 22 patients who meet additional criteria. Inter-rater reliability, test-retest reliability over 24 hours, and convergent validity with Coma Recovery Scale-Revised scores will be analyzed.

Подробное описание

This study is part of the Horizon MSCA DoC-Box project, which aims to develop a multimodal toolbox to support fast and reliable diagnosis of disorders of consciousness. The study includes two consecutive phases. In Phase 1, the original French versions of BERA and SWADOC will be translated into Italian by two expert translators. The translated versions will be synthesized, back-translated into the original language by two independent blinded translators, compared, discussed, and revised by researchers and experts according to international guidelines for translation and cultural adaptation. In Phase 2, the Italian versions will be evaluated in a multicenter observational validation study involving three Fondazione Don Carlo Gnocchi centers (Sant'Angelo dei Lombardi, Florence, Milan) and the IRCCS Istituto Neurologico Carlo Besta in Milan. After diagnostic confirmation based on repeated CRS-R assessments, Examiner A will administer the SECONDs to assess the level of consciousness. On the same day, Examiner B will administer the Italian BERA and/or SWADOC, while Examiner C will independently score the scales to assess inter-rater agreement. After approximately 24 hours, Examiner A will repeat the SECONDs, and either Examiner B or Examiner C will repeat BERA and/or SWADOC to assess test-retest reliability. Demographic and clinical variables, level of consciousness, total scores, and subscale scores will be entered in a centralized pseudonymized REDCap database and analyzed in aggregate form.

Patients with severe acquired brain injury and disorders of consciousness
Consecutive adult inpatients with severe acquired brain injury and a stable diagnosis of disorder of consciousness admitted to one of the four participating centers and meeting eligibility criteria. All eligible participants will undergo SWADOC validation assessments. A nested subgroup of the first 22 participants who also meet BERA-specific criteria will undergo BERA validation assessments.
Диагностический тест: Italian SWallowing Assessment in Disorders of Consciousness (SWADOC)
Structured clinical assessment of oral and pharyngeal swallowing components in patients with disorders of consciousness. The Italian version will be administered and scored by trained examiners to evaluate inter-rater and test-retest reliability.
Диагностический тест: Italian Brief Evaluation of Receptive Aphasia (BERA)
Brief clinical assessment of receptive language abilities, including phonology, semantics, and morphosyntax. Responses are based on visual/eye-movement behavior, allowing assessment of patients unable to communicate verbally or through reliable motor responses. It will be administered to the nested subgroup meeting BERA-specific criteria.

Временное ограничение
Inter-rater reliability of the Italian Swallowing Assessment in Disorders of Consciousness total score
Временное ограничение: Day 1, during the first assessment session
Inter-rater reliability will be assessed for the total score of the Italian version of the Swallowing Assessment in Disorders of Consciousness. The SWADOC total score ranges from 0 to 24, with higher scores indicating better preserved swallowing abilities. The reported outcome will be the intraclass correlation coefficient for agreement between independent raters. The intraclass correlation coefficient is a unitless reliability coefficient ranging from 0 to 1, with higher values indicating greater inter-rater reliability. The SWADOC quantitative scoring system includes 8 scored items rated from 0 to 3, allowing calculation of oral and pharyngeal subscores and a total score.
Day 1, during the first assessment session
Test-retest reliability of the Italian Swallowing Assessment in Disorders of Consciousness total score
Временное ограничение: Baseline and approximately 24 hours later
Test-retest reliability will be assessed for the total score of the Italian version of the Swallowing Assessment in Disorders of Consciousness. The SWADOC total score ranges from 0 to 24, with higher scores indicating better preserved swallowing abilities. The reported outcome will be the intraclass correlation coefficient between the baseline assessment and the reassessment performed approximately 24 hours later. The intraclass correlation coefficient is a unitless reliability coefficient ranging from 0 to 1, with higher values indicating greater test-retest reliability.
Baseline and approximately 24 hours later
Inter-rater reliability of the Italian Brief Evaluation of Receptive Aphasia total score
Временное ограничение: Day 1, during the first assessment session
Inter-rater reliability will be assessed for the total score of the Italian version of the Brief Evaluation of Receptive Aphasia in the eligible subgroup of patients. The BERA total score ranges from 0 to 30, with higher scores indicating better receptive language abilities. The reported outcome will be the intraclass correlation coefficient for agreement between independent raters. The intraclass correlation coefficient is a unitless reliability coefficient ranging from 0 to 1, with higher values indicating greater inter-rater reliability. The BERA includes 30 items per version, with 10 phonological, 10 semantic, and 10 morphosyntactic items; each correct visual fixation response is scored as 1 point and errors or absent fixation as 0 points.

Convergent validity of the Italian Swallowing Assessment in Disorders of Consciousness total score with the Coma Recovery Scale-Revised total score
Временное ограничение: Baseline/Day 1
Convergent validity will be assessed by calculating the Spearman rank correlation coefficient between the total score of the Italian version of the Swallowing Assessment in Disorders of Consciousness and the total score of the Coma Recovery Scale-Revised. The SWADOC total score ranges from 0 to 24, with higher scores indicating better preserved swallowing abilities. The Coma Recovery Scale-Revised total score ranges from 0 to 23, with higher scores indicating a higher level of consciousness. The reported outcome will be Spearman's rho, a unitless correlation coefficient ranging from -1 to +1.
