Spanish version of the Link's Perceived Devaluation and Discrimination scale

Area of Science:

• Psychiatry
• Clinical Psychology
• Psychometrics

Background:

• Self-stigma is a significant issue for individuals with schizophrenia.
• Existing measures may not be culturally adapted for Spanish-speaking populations.

Purpose of the Study:

• To translate, adapt, and validate the Perceived Devaluation and Discrimination Scale (PDD) into Spanish.
• To assess the psychometric properties of the Spanish PDD in schizophrenia patients.

Main Methods:

• Cross-sectional study involving 130 participants diagnosed with schizophrenia (DSM-IV-R).
• Utilized the translated PDD, Social Functioning Scale (SFS), Global Assessment of Functioning (GAF), Clinical Global Impression Scale (CGI-S), and Self-perception of Stigma Questionnaire (SSQ).

Main Results:

• The Spanish PDD demonstrated good internal consistency (Cronbach's α = .868).
• Factor analysis revealed two components: individual self-perception and social stigma, explaining 40% of the variance.
• Instrument stability ranged from .415 to .806 (intraclass correlation coefficient).
• Significant correlations were observed with SSQ and SFS, supporting construct validity.

Conclusions:

• The Spanish version of the PDD is a valid and reliable instrument for measuring self-stigma in schizophrenia.
• This validated scale can be used to evaluate self-stigma in Spanish-speaking populations with schizophrenia.
