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.

Detailed description

Background. Individuals with post-stroke aphasia often experience a profound loss of abilities to engage in social interaction, one major reason for increased risk of depression after a cerebrovascular accident. Impaired communication skills in aphasia can prevent classical forms of psychotherapy, thus emphasizing the need for new rehabilitation strategies alongside antidepressant medication. Aims. The present parallel-group, single-center, blinded-assessment controlled trial seeks to explore the feasibility - in terms of high completion rates (primary outcome) - and potential efficacy (co-primary and secondary outcomes, as defined below) of intensive communicative-pragmatic social interaction for treatment of post-stroke depression in subacute aphasia. In this early time window after a cerebrovascular accident, prevalence of post-stroke depression is generally high. Methods. Treatment is based on a linguistically validated protocol that encourages individuals with aphasia to use neural resources of verbal communication embedded in intensive social interaction. In a routine-healthcare outpatient setting, 60 individuals with post-stroke depression and subacute aphasia will be assigned to one of two groups in a pseudorandomized fashion: (i) intensive communicative-pragmatic social interaction combined with standard care, or (ii) standard care alone. Endpoints and Outcomes. Apart from evidence of treatment feasibility, endpoint will be change on self-report and clinician-rated measures of depression severity (co-primary outcomes: Beck's Depression Inventory, BDI; and Hamilton Rating Scale for Depression, HAM-D) after a 1-month treatment period (5 hours of weekly training). Secondary outcomes include measures evaluating self-efficacy, quality of life, and language performance (secondary outcomes: Self-Efficacy Questionnaire; and Aachen Aphasia Test, AAT). Hypotheses. Aside from evidence of treatment feasibility, the primary hypothesis predicts significant between-group differences on BDI and HAM-D scores, indicating greater reduction in depression severity with intensive communicative-pragmatic social interaction over and above standard care alone. Secondary analyses will focus on the Self-Efficacy Questionnaire as an external criterion to explore the psychometric adequacy of the self-report co-primary outcome, the BDI, and consider progress in language performance from onset to end of treatment on the AAT to account for the potential relationship between change in cognitive-affective distress and verbal expression skills. Clinical Relevance. The current proof-of-concept trial will investigate the feasibility and potential efficacy of intensive communicative-pragmatic social interaction as a means to promote recovery from post-stroke depression in subacute aphasia. The results obtained will determine the design of a subsequent phase-III randomized controlled trial.

Interventions

Type	Name	Description
BEHAVIORAL	Intensive communicative-pragmatic social interaction.	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.
BEHAVIORAL	Standard care.	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.
