Financial resilience-focused program: A single group pretest–posttest intervention to change financial risk perception among teenagers in an ethnic minority poverty-stricken area in China

•There is a reasonable range for financial risk perception, and neither too high nor too low is reasonable.•Teenagers with different initial financial risk perceptions respond differently to the same intervention.•Teenagers in low-risk perception group show more pronounced changes after intervention than those in high-risk perception group.•Bayesian statistical analysis is used for small samples to enhance the confidence of the results. This study examined the effects of a single-group pretest–posttest intervention in changing the level of financial risk perceptions among teenagers from the perspective of the financial resilience framework. 37 teenagers completed the six-week nonrandomised intervention with follow-up tests at Weeks 8 and 22. Based on the pretest scores of the Internet Financial Risk Perception Scale, the participants were divided into high- and low-risk perception groups. Bayesian repeated variance analysis was then used to evaluate the influence of the intervention on financial risk perception. Compared with the baseline level, the low-risk perception group showed an increase in total financial risk perception and each subdimension. Decreased changes were observed in the long term, although no sufficient evidence was found for changes in the high-risk perception group after the intervention. The financial resilience-focused framework and its corresponding program neutralizes the perceived risk. Furthermore, similar interventions should consider the initial level of risk perception among participants.
