摘要

The present study investigates age and gender differences in deceptive behavior of adolescents, using a multi-informant approach. Cross-sectional data from a large, multinational dataset was used, including 25,643 participants aged 11–18 years across 24 societies, using the Child Behavior Checklist (CBCL) and Youth Self-Report (YSR). Mixed models were applied to examine linear and curvilinear age trends, gender differences, and discrepancies between self- and parental reports on lying and cheating. Boys consistently showed higher frequencies of deceptive behavior across all ages and informants, highlighting a robust gender difference. Also, significant mean-level age trends were found, which however differed across informants. Adolescents’ self-reports showed an inverted U-shape pattern in the frequency of deception with growing age, peaking around mid-adolescence, while parental reports showed a U-shaped trend in their child’s frequency of deception across a similar age span, although curvilinearity was less pronounced. The highest discrepancy between self- and parental reports was situated in mid-adolescence, likely due to both a parental truth bias and the increased sophistication of adolescents in distorting the truth. Using polynomial regression, subsequent analyses showed that agreement between children and parents on high levels of deception was linked to the highest (predicted) levels of externalizing problems in adolescents. In contrast, disagreement (with adolescents reporting high deception and parents reporting low deception) predicted the highest levels of internalizing problems, but only for child-reported internalizing problems. These findings suggest that parent–child informant discrepancies on deceptive behavior are clinically significant and may offer unique insights into adolescent internalizing and externalizing problems.
