In this study, 25 sixth grade primary school students kept the newly created “one-month pocketbook” for about 6 months. Questionnaires were distributed to parents and children about their interest in money after using the “one-month pocketbook.”

  It was observed that children maintained their interest in money but also became more aware of family welfare. Moreover, children could grasp their financial situation and think about money from various aspects by keeping the “one-month pocketbook”. Previous research produced the same result. As for parents, more tended to give pocket money to their children after using the “one-month pocketbook” and they realized that children's interest in money had stayed at a high level. This was the same result as that of previous research. The parents' comments did not influence the children's behavior. The major difference between this and previous research is that parents realized that children's attitudes had changed after just 5 months.
