Randomized Controlled TrialSun protection changes among diverse elementary schoolchildren participating in a sun safety intervention: A latent transition analysis of a randomized controlled trial.
Children are a priority population for skin cancer prevention as excessive sun exposure in childhood increases the risk of melanoma in adulthood. The complexity of sun protective behaviors has posed measurement challenges for trials testing intervention efficacy. The current study evaluated a sun safety intervention for schoolchildren using latent transition analysis (LTA) to examine patterns of sun protection behaviors over time. ⋯ In this RCT of a sun safety intervention, children in the intervention transitioned to more protective behaviors compared to controls. Using LTA enriches understanding of intervention efficacy by modeling the complexity of sun protection behaviors over time.
