The Development and Psychometric Validation of the Partner Investment in Health and Physical Activity Scales
Student Initiated Study by: Stephanie Callan, MA
The goal of this research was to assess the psychometric properties of the Partner Investment in Health Scale (PI-H) and the Partner Investment in Physical Activity Scale (PI-A), which were developed to assess the degree to which partners in a couple are invested in one another’s health and wellbeing. Specifically, we examined the reliability and validity of the measure, as well as the measures' relationships with related constructs like social support, social control, and relationship satisfaction. Data was collected using the Qualtrics platform and Amazon Mechanical Turk. This project is complete and the results have been published. Future directions of this project include examining this scale specific to other health behaviors (e.g., sleep, diet) and in other populations (cancer, transition to parenthood), for which data have already been collected.
