Summary
The Child Behavior Checklist for ages 1.5-5 (CBCL/1½-5) DSM-ASD scale shows strong cross-cultural reliability for screening Autism Spectrum Disorder (ASD). Specific items demonstrate potential for accurate ASD identification globally.
Area of Science:
- Child Psychology
- Psychometrics
- Developmental Disorders
Background:
- The Child Behavior Checklist for ages 1.5-5 (CBCL/1½-5) DSM-ASD scale is a validated Level 1 screener for Autism Spectrum Disorder (ASD).
- Previous versions, like the DSM-PDP scale, also demonstrated utility in ASD screening.
Purpose of the Study:
- To evaluate the measurement invariance and psychometric robustness of the CBCL/1½-5 DSM-ASD scale across diverse international populations.
- To identify specific items within the scale that may serve as strong discriminators for ASD.
Main Methods:
- Confirmatory factor analyses (CFAs) were conducted using a large dataset (N=19,850) from population samples across 24 societies.
- Measurement invariance (configural and metric) was assessed to determine cross-cultural consistency.
Main Results:
- The CBCL/1½-5 DSM-ASD scale demonstrated good measurement invariance across the studied societies, particularly at the configural and metric levels.
- Items 4, 25, 67, 80, and 98 showed promising characteristics, including low base rates, strong loadings on the ASD construct, and high measurement invariance.
Conclusions:
- The findings support the international psychometric robustness and cross-cultural validity of the CBCL/1½-5 DSM-ASD scale for ASD screening.
- Further research is recommended to confirm the discriminative power of the identified key items in predicting ASD diagnoses.

Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.
In contrast, source traits are the...

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:29Theoretical Approaches to Psychological Disorder

The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...
