Validation of the Eight-Item Paranoid Thoughts Scale (GPTS-8) in Tunisian Arab Adults
Background
Growing research indicated that it is highly valuable and clinically beneficial to quantitatively measure and detect the potential presence of paranoid thinking. Among the various existing self-report instruments to measure paranoia, the Green et al. Paranoid Thoughts Scale (GPTS) was recommended as having the most well-defined, clearly articulated construct underlying its items, and the strongest psychometric qualities in general and clinical population samples. Yet, the psychometric performance of the GPTS remains unknown in the Arab language and culture. To address this gap, our study aimed to explore the psychometric properties of an Arabic translation of the shortest version of the scale (i.e., the GPTS-8).
Methods
A cross-sectional study was conducted. Data were collected during the period September 1st 2024 to January 31th 2025. A total of 552 Arabic-speaking general population adults from Tunisia aged 25.81 ± 4.86 years participated.
Results
Analyses provided support for a bidimensional model, with a first dimension referring to ideas of persecution and a second one corresponding to ideas of reference. The internal consistency reliability coefficients were high, with both Cronbach's alpha and McDonald's ω reported to be 0.83 for ideas of persecution and 0.83 for ideas of reference. Measurement invariance was established for both subscales, implying that the Arabic GPTS-8 measures the same underlying construct of paranoia in the same way across male and female respondents. Finally, paranoia scores correlated positively with psychotic experiences scores, indicating convergent validity, as well as with depression, anxiety and insomnia scores, supporting the concurrent validity of the scale.
Conclusion
By translating and validating GPTS-8 for the first time in Arabic, this study contributes to rendering the tool available to a broader array of clinicians and researchers who work with Arabic-speaking people. We believe the new Arabic version of the GPTS-8 will provide further encouragement to research and development in this yet-unexplored field among Arabic-speakers.
期刊介绍：
The International Journal of Methods in Psychiatric Research (MPR) publishes high-standard original research of a technical, methodological, experimental and clinical nature, contributing to the theory, methodology, practice and evaluation of mental and behavioural disorders. The journal targets in particular detailed methodological and design papers from major national and international multicentre studies. There is a close working relationship with the US National Institute of Mental Health, the World Health Organisation (WHO) Diagnostic Instruments Committees, as well as several other European and international organisations.
MPR aims to publish rapidly articles of highest methodological quality in such areas as epidemiology, biostatistics, generics, psychopharmacology, psychology and the neurosciences. Articles informing about innovative and critical methodological, statistical and clinical issues, including nosology, can be submitted as regular papers and brief reports. Reviews are only occasionally accepted.
MPR seeks to monitor, discuss, influence and improve the standards of mental health and behavioral neuroscience research by providing a platform for rapid publication of outstanding contributions. As a quarterly journal MPR is a major source of information and ideas and is an important medium for students, clinicians and researchers in psychiatry, clinical psychology, epidemiology and the allied disciplines in the mental health field.
