Background: Communication is at the heart of relationships, especially for couples. When language is altered, as it is in aphasia, communication in couples can be affected. Aims: To explore how members of a couple perceive the impact of aphasia on their communication. Methods & Procedures: Nine French-speaking couples participated in the study. One member of each couple had chronic stroke-related aphasia, which varied in type and severity. The 18 participants took part in individual semi-structured interviews to understand their perspective on communication within their couple. The interviews were recorded, transcribed and analysed with a qualitative thematic analysis. Outcomes & Results: Three main themes emerged: (1) experiencing limitations in conversation; (2) assuming changed speaking and listening roles; and (3) experiencing new emotions, feelings and reactions in communication. Couples experienced diminished frequency and duration of conversations as well as restrained topics after the onset of aphasia. Ten participants reported that each member's communication role of listener versus speaker had changed, and that the person with aphasia became a less active participant. Communication was described as 'positive' before aphasia and 'fine' to 'difficult' following aphasia. Persons with aphasia and spouses expressed experiencing difficulties managing emotions related to communication. Frustration and caution towards the other member of the couple had been associated with aphasia. In addition, five spouses reported that they refrained from initiating discussions on specific topics in order to maintain a positive relationship with the person with aphasia. Conclusion & Implications: The results describe some of the consequences of aphasia on communication in couples. Clinicians could use interviews to understand the impact of aphasia on a couple's communication. This may help to design communication partner training (CPT) that better aligns with the particular needs of couples living with aphasia, acknowledging the importance of emotional dimensions of relationships.
