<p>Parent–adolescent discrepancies in perceptions of parenting may reflect meaningful relational dynamics with implications for adolescent development. Guided by self-determination theory, this study examined discrepancies between adolescents’ and parents’ perceptions of parental nurturance and their associations with adolescent adjustment in South Korea. Data were drawn from 361 adolescent–parent dyads from six middle schools and five high schools across diverse regions. Parallel adolescent- and parent-report measures assessed six subdomains of parental nurturance: respect for opinions, respect for interests, relationship with parents, relationship with other family members, value of academic achievement, and trust in potential. Paired-samples <i>t</i> tests showed that parents rated parental nurturance more positively than adolescents across all six subdomains. Latent profile analysis identified three discrepancy profiles: Small Gap, Moderate Gap, and Large Gap. The Small Gap profile showed high nurturance and minimal discrepancy, the Moderate Gap profile showed moderate nurturance and a moderate parent-favoring discrepancy, and the Large Gap profile showed the lowest nurturance and the largest discrepancy. Multinomial logistic regression analyses indicated that higher psychological well-being and more positive peer relationships were consistently associated with membership in more favorable profiles, whereas perceived academic performance distinguished the Moderate Gap and Large Gap profiles only. These findings suggest that parent–adolescent discrepancies in parental nurturance are meaningfully associated with adolescent adjustment and highlight the importance of family environments that adolescents perceive as supportive and nurturing.</p>
