Abstract(s)
The objective of the present research is to examine the factor structure of the Interpersonal
Behavior Questionnaire (IBQ) and the Interpersonal Behavior Self Questionnaire (IBQ-Self) in the
sport context. Confirmatory factor analyses were used to assess the psychometric properties and
measurement invariance across sex and sports. For the IBQ, a sample of 813 Portuguese athletes
aged between 15 and 32 years (M = 23.46; SD = 4.92) took part in this study. They had an average
sports experience of approximately 7.62 ± 3.23 years. For the IBQ-Self, a sample of 606 Portuguese
coaches aged between 20 and 73 years (M = 34.43; SD = 11.56) participated in this study. Both
scales demonstrated good fit, achieved convergent and discriminant validity, exhibited acceptable
internal consistency, and demonstrated invariance across sex and sports. Regarding the analysis of
psychometric properties, the IBQ and IBQ-Self can be applied to Portuguese athletes and their
coaches to measure perceived behaviors of others and self-reported behaviors.
