Description of intervention(s) / exposure
CBSM:
Participants will complete one module of Cognitive Behavioural Stress Management (CBSM; Antoni, 2003) Therapy delivered by a digital human. This module will take place at the University of Auckland Clinical Research Centre. Participants will complete this module of CBSM in a private room on a secure University computer screen. This CBSM session includes psychoeducation surrounding the effects of stress on the body and mind, and involves learning a stress management technique: deep breathing. The digital human uses a conversational engine (IBM Watson Agent) to power her conversation flows. The CBSM module is developed from Antoni’s (2000) manual for CBSM in breast cancer patients.

The digital human is called Rosie, delivering this module of CBSM therapy via a computer screen. Rosie, the digital human being used in this study was modelled to be a female adult providing relatability to the target population. Rosie is presented wearing a white T-shirt and upon a lightly pink background, so her face and communication abilities are of central focus on the screen. During sessions, her natural body movements are paired with natural facial expressions, depending on the topic of conversation and in response to the user’s expression. Text-to-speech Emotional Markup Language (EML; Sagar et al., 2014; Sagar et al., 2016) is utilised to allow Rosie to display certain facial expressions, such as a smile, when she mentioned certain phrases or words, such as affirmative statements. Her voice was programmed to have an Australian ‘Neural’ accent, with natural inclinations and pronunciation used within New Zealand society, making her more applicable to the target population.
Participants will verbally or text to communicate with the digital human Rosie. The session will last for a duration of approximately 60-minutes, with the natural conversation/session length becoming a marker for intervention adherence.

Practicality of recruitment will be assessed upon the conclusion of the study. This will be assessed when recruitment targets have been met, and data collection has been completed.

Technical difficulties will be assessed throughout the session and immediately post-intervention by the researcher noting how many difficulties are encountered during and after the session.

Coverage of measures will be assessed upon conclusion of the study, once recruitment targets have been met and data collection is complete.
