Abstract

Objective: This study aimed to translate the Perceived Stress Scale, the Compulsive Buying Scale, and the Ruminative Responses Scale into Arabic, confirm their factorial structure, assess reliability, and examine measurement invariance across genders.
Methods: A five-stage translation and verification process resulted in Arabic versions of the scales. A study was conducted using a sample of Saudi adults (N=500) to evaluate their psychometric properties. Confirmatory factor analyses, measurement invariance, and internal consistency reliability assessments were employed for validation.
Results: For the Perceived Stress Scale, the measurement model with two correlated factors provided a good fit (CFI = .93, AGFI = .91, IFI = .93, TLI = .92, RMSEA = .063). Strict invariance was held across genders (CFI = .914, RMSEA = .045), with a Cronbach’s alpha of .84. For the revised Edwards Compulsive Buying Scale, the model with four correlated factors showed a good fit (CFI = .94, AGFI = .91, IFI = .94, TLI = .92, RMSEA = .057). Strict invariance was achieved across genders (CFI = .913, RMSEA = .044), and Cronbach’s alpha was .84. For the Ruminative Responses Scale, the model with two correlated factors indicated a good fit (CFI = .97, AGFI = .94, IFI = .97, TLI = .95, RMSEA = .063). Strict invariance was attained across genders (CFI = .973, RMSEA = .033), with a Cronbach’s alpha of .85.
Conclusions: The results support the robustness and utility of these scales for research and clinical settings for Arabic-speaking populations in Saudi Arabia.
