The internal and external validity of sluggish cognitive tempo (SCT) relative to attention-deficit/hyperactivity disorder-inattention (ADHD-IN) was evaluated with Turkish children and adolescents. Parents completed the SCT, ADHD-IN, ADHD-hyperactivity/impulsivity (HI), oppositional defiant disorder (ODD), callous-unemotional (CU), anxiety, depression, social impairment, and academic impairment scales of the Child and Adolescent Behavior Inventory (CABI) on 1015 Turkish children and adolescents (56% girls; ages 6–15 years; M_age = 10.05, SD_age = 2.32), including 762 recruited from the community and 253 recruited from outpatient psychiatric clinics. SCT symptoms demonstrated excellent internal validity with the ADHD-IN symptoms. SCT symptoms also showed invariance across boys and girls as well as across community and clinical samples. SCT showed stronger first-order and unique associations than ADHD-IN with anxiety and depression whereas ADHD-IN showed stronger first-order and unique associations than SCT with ADHD-HI, ODD, and academic impairment. SCT and ADHD-IN showed equal associations with CU behaviors and social impairment. The current study is the first to support the validity of CABI SCT scores with Turkish children and adolescents and also replicates the findings from similar studies with children from South Korea, Spain, and United States. These findings thus further strengthen the transcultural validity of CABI SCT scale scores.

相对于注意力缺陷/多动症-注意力不集中（ADHD-IN）相对缓慢的认知节奏（SCT）的内部和外部有效性进行了评估，与土耳其儿童和青少年。家长填写了儿童和青少年行为量表的SCT，ADHD-IN，ADHD多动症/冲动（HI），对立违抗性障碍（ODD），无情无情（CU），焦虑，抑郁，社交障碍和学业障碍量表（CABI）对1015名土耳其儿童和青少年（56％的女孩； 6至15岁；M_年龄 = 10.05，SD_年龄） = 2.32），其中包括从社区招募的762名和从门诊精神病诊所招募的253名。SCT症状与ADHD-IN症状表现出极好的内部有效性。SCT症状在男孩和女孩之间以及社区和临床样本之间也显示出不变性。与焦虑和抑郁症的ADHD-IN相比，SCT显示出更强的一阶和独特关联，而与ADHD-HI，ODD和学术障碍相比，ADHD-IN显示出更强的一阶和独特关联。SCT和ADHD-IN与CU行为和社会障碍具有同等关联。当前的研究是第一个支持CABI SCT评分对土耳其儿童和青少年有效的研究，并且也重复了对来自韩国，西班牙和美国的儿童进行的类似研究的结果。
