Summary
The Spanish adaptation of the Positive and Negative Syndrome Scale (PANSS-S) shows reliable and valid psychometric properties. This Spanish PANSS version is equivalent to the original, enabling cross-cultural schizophrenia research.
Area of Science:
- Psychiatry
- Clinical Psychology
- Psychopathology Assessment
Background:
- The Positive and Negative Syndrome Scale (PANSS) is a key tool for schizophrenia assessment.
- Cross-cultural and multinational research requires validated assessment tools in multiple languages.
- A Spanish adaptation (PANSS-S) was developed to address this need.
Purpose of the Study:
- To evaluate the psychometric equivalence of the Spanish adaptation of the PANSS (PANSS-S).
- To determine if PANSS-S can be used interchangeably with the original PANSS in Spanish-speaking populations.
Main Methods:
- Two bilingual psychiatrists simultaneously rated 57 psychiatric inpatients.
- Patients were assessed using the original PANSS, PANSS-S, or both.
- Interrater reliability and criterion-related validity were analyzed.
Main Results:
- PANSS-S demonstrated strong interrater reliabilities (positive syndrome r = .93; negative syndrome r = .74).
- The Spanish version showed comparable means and variances to the original PANSS.
- Significant cross-correlations confirmed validity for scales and symptom clusters.
Conclusions:
- The PANSS-S exhibits psychometric properties similar to the original PANSS.
- The PANSS-S is a valid and reliable instrument for assessing psychopathology in Spanish-speaking schizophrenia patients.
- This adaptation facilitates international and cross-cultural research on schizophrenia.
