Beskrivelse
Inclusion Criteria:
- Age >= 18 years.
- Native Italian speaker.
- Diagnosis of severe acquired brain injury.
- At least 28 days since the acute event.
- For SWADOC validation: stable clinical diagnosis of disorder of consciousness, including UWS, MCS, or EMCS, assessed with the Coma Recovery Scale-Revised repeated at least five times over two weeks.
- For BERA validation: stable clinical diagnosis of MCS or EMCS assessed with the Coma Recovery Scale-Revised repeated at least five times over two weeks.
- For BERA validation: presence of visual fixation and/or visual pursuit assessed with the Coma Recovery Scale-Revised.
- No remote history of neurological, neurodegenerative, or psychiatric disease; for SWADOC validation, no remote history of otorhinolaryngological disease.
- Written informed consent provided by the primary caregiver/legal representative according to local regulations.
Exclusion Criteria:
- Occurrence of a second cerebral event between enrollment and data collection.
- Unstable general clinical condition preventing assessment, including but not limited to need for ventilatory support, severe infection, or status epilepticus.

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.
|
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.
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.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Inter-rater reliability of the Italian Swallowing Assessment in Disorders of Consciousness total score
Tidsramme: 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.

Test-retest reliability of the Italian Swallowing Assessment in Disorders of Consciousness total score
Tidsramme: 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.

Inter-rater reliability of the Italian Brief Evaluation of Receptive Aphasia total score
Tidsramme: 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
Tidsramme: 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.
