Feasibility of using ecological momentary assessment to measure the effects of interactions with pet dogs on psychophysiological reactivity in adolescents with social anxiety

Adolescence is a key developmental period for the onset of social anxiety, as it is a time of social transitions and stressors. Therefore, it is important to identify protective factors within the environment that can prevent and/or reduce the effects of social anxiety in addition to existing evidence-based treatments. The presence of a supportive pet dog may be one way of reducing the effects of acute social stressors for youth, but these effects have not been tested robustly in real-world settings. This study aimed to assess the feasibility of using ecological momentary assessment (EMA) to assess physiological responses to pet interactions in real-life scenarios among adolescents with social anxiety (n = 37). Results indicated that this protocol was perceived as feasible by youth participants and allowed for integration across different data streams. Participant use of a wearable sensor to collect electrodermal activity was generally successful, with an average of 12 h of data collected per participant. However, the use of a timestamp button on the sensor was not an effective strategy for data collection. These findings suggest that EMA using self-report activity diary data combined with continuous psychophysiological measurement using wearable sensors is generally a feasible person-centered approach for measuring adolescent-dog interactions in a way that maintains ecological validity.
