Bedtime procrastination is generally considered to be a maladaptive behavior. However, BP may be an adaptive fast LH strategy within the LH framework, and further, personal beliefs about their abilities and resources promote this fast LH strategy. Here, the present study addressed this idea, focusing on the effect of self-efficacy on BP, the mediation of harm avoidance, and the moderation of novelty seeking. Data from 552 Chinese university students were analyzed using SPSS 25.0 and SPSS PROCESS Macro. Results indicated that (...) HA partially mediates the relationship between self-efficacy and BP. Main interactional effects have been observed when NS is introduced in the model as a moderator. Implications and limitations of the study and suggestions for further study are discussed. (shrink)
