Exploring effects of childhood parentification on adult-depressive symptoms in Korean college students.

Objective: This study explored parentification dimensions, the age of onset, duration, and family circumstances to better understand the characteristics of parentification and its impact on depressive symptoms among Korean college students.

Method: A sample of South Korean college students (N = 316, aged 18-29 years, 66.1% female) rated their childhood parentification experiences and current depressive symptoms.

Can Sluggish Cognitive Tempo Be Distinguished From ADHD Inattention in Very Young Children? Evidence From a Sample of Korean Preschool Children.

Objective: This study evaluated whether sluggish cognitive tempo (SCT) is separable from ADHD-inattention (IN) and uniquely associated with internalizing dimensions in preschool children in South Korea.

Method: Mothers of 172 preschool children (ages 4-6 years; 52% girls) rated children's SCT, ADHD-IN, ADHD-hyperactivity/impulsivity (HI), oppositional defiant disorder (ODD), aggression, emotional reactivity, anxiety/depression, somatic complaints, withdrawal, and sleep problems.

Results: Eight of 10 SCT symptoms showed convergent and discriminant validity with ADHD-IN.

Toward Establishing the Transcultural Validity of Sluggish Cognitive Tempo: Evidence From a Sample of South Korean Children.

All sluggish cognitive tempo (SCT) research has been conducted in North America and Western Europe, with the addition of 1 study in Chile. Our objective was to determine the internal and external validity of 9 SCT and 9 Diagnostic and Statistical Manual of Mental Disorders (5th ed.) attention deficit/hyperactivity disorder inattention (ADHD-IN) symptoms in South Korean children.

Bifactor latent structure of attention-deficit/hyperactivity disorder (ADHD)/oppositional defiant disorder (ODD) symptoms and first-order latent structure of sluggish cognitive tempo symptoms.

The objective was to determine if the latent structure of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms is best explained by a general disruptive behavior factor along with specific inattention (IN), hyperactivity/impulsivity (HI), and ODD factors (a bifactor model) whereas the latent structure of sluggish cognitive tempo (SCT) symptoms is best explained by a first-order factor independent of the bifactor model of ADHD/ODD. Parents' (n = 703) and teachers' (n = 366) ratings of SCT, ADHD-IN, ADHD-HI, and ODD symptoms on the Child and Adolescent Disruptive Behavior Inventory (CADBI) in a community sample of children (ages 5-13; 55% girls) were used to evaluate 4 models of symptom organization. Results indicated that a bifactor model of ADHD/ODD symptoms, in conjunction with a separate first-order SCT factor, was the best model for both parent and teacher ratings.

Validity of the sluggish cognitive tempo symptom dimension in children: sluggish cognitive tempo and ADHD-inattention as distinct symptom dimensions.

This study examined the validity of the sluggish cognitive tempo (SCT) symptom dimension in children. Ten symptom domains were used to define SCT (i.e.
