Evidence on method dissatisfaction among current contraceptive users is sparse. Group-based trajectory modeling presents a novel approach to describing method dissatisfaction.In a cohort of Kenyan women using modern contraception, we identified group-based trajectories of method dissatisfaction over 24 weeks since clinic visit.Among 947 women, four trajectories were identified: consistent satisfaction (71%), increasing dissatisfaction (18%), decreasing dissatisfaction (8%), and consistent dissatisfaction (3%).Method dissatisfaction was common in a cohort of Kenyan women. Group-based trajectory models describe distinct and changing experiences of contraceptive use. Deeper understanding of trajectories of contraceptive experience may be useful for advancing person-centered family planning care that addresses users' changing preferences and challenges.
