**5.2 Limitations and further research**

As indicated above, the casual relationship between mother's personality and children's creativity is complicated. TCAM, an instrument widely used to tap young children's creativity, does not include "elaboration" in children's creativity, so elaboration is neither measured nor discussed in this study. There may be other possible factors affecting children's creativity, e.g., their socio-economic background and maternal education. Besides, in future research, the sample size needs to be larger for multiple regression. Further studies can explore other potential factors influencing young children's creativity. And our mediation methods used here may be fairly exploratory, especially the use of single items. In particular, the single item NGA (no guidelines at all) correlated with all three creativity dimensions. Future research can develop a scale with more items and correlate with creativity. This study employed a correlational design and hence an experimental design can be considered in the future.
