Counselling practice has been supported by the development and use of interventions that are situated around overcontrol (OC) and under-control (UC) personality characteristics. Although related measures are currently available for young children (Gilbert et al., 2020a) and adults (Seretis, 2017), the advancement of counselling practice and related research across international samples can be enhanced through the development and validation of a measure suitable for use with older children and adolescents. We implemented a cross-sectional psychometric validation with 438 young people (M_age = 13.96, SD = 1.59) in south-east London which resulted in preliminary evidence for the Youth Over- and Under-Control (YOU-C) measure, 2-factor solution represented by Overcontrol (14 items) and Under-Control (11 items) subscales that accounted for 33.01% of variance among scores. Reliability estimates indicted suitability for basic research purposes, but not clinical decision-making activities. No statistically significant differences were identified based on gender or age.

围绕过度控制（OC）和控制不足（UC）人格特征的干预措施的开发和使用为咨询实践提供了支持。尽管目前有针对年幼儿童（Gilbert等，2020a）和成人（Seretis，2017）的相关措施，但通过制定和验证适合使用的措施，可以提高国际样本咨询实践和相关研究的进展与年龄较大的儿童和青少年。我们对438名年轻人（M_年龄 = 13.96，SD = 1.59）在伦敦东南部，这为青少年过度控制和控制不足（YOU-C）措施，以过度控制（14个项目）和控制不足（11个项目）分量表表示的两因素解决方案提供了初步证据，占分数方差的33.01％。可靠性评估表明适用于基础研究，但不适用于临床决策活动。没有发现基于性别或年龄的统计学差异。
