Abstract
Schema Therapy aims to regulate dysfunctional schemas that develop early in life
and persist into adulthood. This approach incorporates a range of theoretical frameworks,
including cognitive behavioral therapy, psychodynamic therapy, attachment
theory, and gestalt therapy. This study aims to examine the psychometric properties
of the Young Positive Schema Questionnaire (YPSQ) in an adolescent sample. The
YPSQ was developed by Louis et al. (Psychol Assess 30(9):1199, 2018) and subsequently
adapted to a Turkish adult sample by Velibaşoğlu (2021). The sample of
the present study comprised 777 adolescents enrolled in high school. Confirmatory
factor analysis (CFA) was performed to assess the factor structure of the scale and
the 14-factor structure was confirmed with 55 items (χ2/df = 1.90, RMSEA = 0.03,
CFI = 0.97, NFI = 0.96, GFI = 0.98, AGFI = 0.97). Item 53 in the original scale was
eliminated due to a factor loading below 0.30. The factor loadings of the scale items
range between 0.43 and 0.82. The criterion-related validity of the scale was assessed
by examining the relationship between the Young Positive Schema Questionnaire
and the Flourishing Scale. As a result, a high level of correlation was identified between
positive schemas and psychological well-being (r = .73, p < .01). The internal
consistency of the sub-factors of the scale was assessed by examining the mean
inter-item correlations, which ranged from 0.25 to 0.51. Consequently, the 14-factor
structure of the scale was found to be compatible with both the original scale and
the theoretical framework. The scale demonstrated adequate internal consistency.
The correlation of the Young Positive Schema Questionnaire and its sub-dimensions
with psychological well-being indicates satisfactory criterion-related validity.
