Completed

• Conditions: Mental Health Services; Personality

• Registration Number: NCT05952063
• Lead Sponsor: 40FY

Brief Summary

Digital Mental Health Service, MINDLiNG, has developed Schema Scale that identifies individual's personality based on schema theory. The goal of this study is to determine the reliability and validity of the Schema Scale.

Detailed Description

Most of the mental health service programs are limited to targeting specific psychiatric symptoms, which does not necessarily consider the personality and characteristics of individuals. To provide more personalized mental health care service, it is essential to identify the personality of individuals through valid psychological test.

Thus, MINDLiNG has developed the Schema Scale based on schema theory and psychodynamic theory in order to provide personalized and evidence-based treatment at the level of psychotherapy.

This study was conducted to evaluate the validity and reliability of the Schema Scale. The scale was administered online on non-clinical population (n = 234). The internal consistency of Schema Scale was evaluated. In addition, its factor structured was studied by exploratory and confirmatory factor analyses. Concurrent validity was examined by comparing the extracted Schema Scale factors with other psychological tests using Pearson's correlation tests.
