Validation of the Four-Dimensional Connectedness Scale in a Multisample Volunteer Study: A Distinct Construct from Work Engagement and Organisational Commitment

This study examines the psychometric properties of a new self-report instrument to measure organisational connectedness (The
Four-Dimensional Connectedness Scale; 4DCS) in two volunteer samples: state emergency service volunteers and volunteer ambulance
workers. Confirmatory factor analyses in both studies supported the proposed four-factor structure of the 4DCS (other workers,
recipients, task and values). In addition, confirmatory factor analyses showed that connectedness, commitment and engagement
were separate constructs—a three-factor model with a Connectedness factor, a Commitment factor and an Engagement factor fitted
best to the data. Moreover, hierarchical multiple regression analyses revealed that connectedness and engagement each shared
unique variance with job satisfaction and intention to continue. The results confirm the factorial, discriminant and predictive
validity of connectedness relative to engagement and commitment. It is concluded that the 4DCS has acceptable psychometric
properties and that the instrument can be used to study volunteer wellbeing.
