NCT04318951

Brief Summary

The present parallel-group, single-center, blinded-assessment controlled trial seeks to explore the feasibility - in terms of high completion rates - and potential efficacy of intensive communicative-pragmatic social interaction for treatment of post stroke depression in subacute aphasia. Apart from evidence of treatment feasibility, the primary hypothesis predicts significantly greater progress on self-report and clinician-rated measures of depression severity after (i) intensive communicative-pragmatic social interaction combined with standard care, compared to (ii) standard care alone.

Outcome Measures

Primary Outcomes (2)

  • Change in Beck's Depression Inventory, BDI.

    This self-report measure of depression severity is derived from a standardized questionnaire known for its good psychometric properties, including construct validity and test-retest reliability, in individuals without aphasia. Scale range: 0-120. Higher values represent higher degree of depression.

    Change from 1 day before start of treatment until immediately after 4 weeks of treatment.

  • Change in Hamilton Rating Scale for Depression, HAM-D. Higher Values Represent Higher Degree of Depression.

    This clinician-rated measure of depression severity is known for its good psychometric properties, including construct validity and test-retest reliability, in individuals without aphasia. Scale range: 0-35.

    Change from 1 day before start of treatment until immediately after 4 weeks of treatment.

Secondary Outcomes (1)

  • Self-Efficacy Questionnaire.

    Immediately after 4 weeks of treatment (used only as an external criterion to explore the psychometric adequacy of the self-report co-primary outcome, the BDI)

Other Outcomes (1)

  • Change in Aachen Aphasia Test, AAT.

    Change from 1 day before start of treatment until immediately after 4 weeks of treatment.

Study Arms (2)

Intensive communicative-pragmatic social interaction.

EXPERIMENTAL

Intensive Language-Action Therapy (ILAT).

Behavioral: Intensive communicative-pragmatic social interaction.Behavioral: Standard care.

Standard care.

OTHER

All participants will receive standard care.

Behavioral: Standard care.

Interventions

ILAT requires individuals with aphasia to engage in social interaction. Groups of three patients and a therapist are seated around a table and provided with picture cards showing different objects (e.g., bottle). Each card has a duplicate that is owned by one of the other players. The goal is to obtain this duplicate from a fellow player by requesting the depicted object (e.g., "Give me the \[…\]"). If the duplicate is available, the addressee hands over the corresponding card to the person who initiated the request sequence. If the duplicate is not available, the addressee rejects the request. In the event of misunderstandings, the players ask clarifying questions. Throughout the training, participants use formulaic expressions to indicate whether a request is accepted ("Here you are," "Thank you," "You're welcome"), rejected ("I'm sorry," "No problem," "Too bad") or unclear ("Pardon me?"). Treatment duration will be four weeks.

Intensive communicative-pragmatic social interaction.
Standard care.BEHAVIORAL

Depending on the participants' diagnoses and needs, standard care will include: occupational therapy (2-3 hours of weekly practice), physiotherapy (3 hours of weekly practice), and speech-language therapy (2-3 hours of weekly practice with non-communicative, impairment-specific exercises). Standard care will be delivered in accordance with state-of-the-art procedures in rehabilitation centers certified in Germany. Treatment duration will be four weeks.

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Left-hemisphere cortical or subcortical stroke;
  • Native speaker of German;
  • Right-handedness according to the Edinburgh Handedness Inventory (Oldfield, 1971);
  • Diagnosis of post-stroke depression, as defined in the International Statistical Classification of Diseases and Related Health Problems (ICD-11);
  • Diagnosis of aphasia, as confirmed by standardized tests (e.g., Huber et al., 1984); and
  • Late subacute or consolidation phase (i.e., 0.5-6 months following stroke) where risk of post-stroke depression is particularly high (Shi et al., 2014).

You may not qualify if:

  • Other neurological conditions;
  • Pre-morbid history of depression;
  • Other psychopathological conditions;
  • Severely impaired vision or hearing that may prevent participants from engaging in intensive communicative-pragmatic social interaction during therapy or testing, thus adopting routine-healthcare standards from a large-scale phase-III randomized controlled trial (Breitenstein et al., 2017);
  • Serious non-verbal cognitive deficits; and
  • No informed consent.
