This study employed the media uses and gratifications model to examine the needs and motives of Instagram users that predict self-disclosure use. Students from the Gulf University of Science and Technology, Kuwait, were surveyed for this study. This study suggests that Instagram provides categories of needs and motives similar in nature to those of the other social media such as self-expression, social interaction, entertainment and opinion exchange. It also caters to the need for experimenting with photography that few available social media satisfy. Self-expression and social interaction needs were the strongest predictors of the use of Instagram for self-disclosure on all its dimensions, that is, honesty, amount, positive valence and depth. Other intersecting factors such as biological sex and frequency of use showed different patterns of use. The implications of Arab culture on Instagram use are discussed since Kuwaiti culture, as opposed to the Western cultures, is more collectivist in nature.
