An array of communication technology, such as text messaging, social networking sites, and mobile apps, have become the platforms through which many self-disclosures take place. This brings forth questions about which factors determine media selection for self-disclosure, such as media appropriateness and efficiency. Survey participants (N = 598) indicated modality preferences for disclosing hypothetical negative, positive, private, and public scenarios to a friend. For positive or public disclosures, modalities considered most convenient were more likely to be chosen; for negative or private disclosures, participants were more likely to select modalities that were considered most appropriate. Results also show a discrepancy between perceptions of appropriateness and motivations for media selection. These findings present implications for the balance between media appropriateness and efficiency in self-disclosure strategies.
