Validation of the Thai version of the Savoring Beliefs Inventory of elderly cancer patients and their family caregivers in Thailand

Abstract

Savoring refers to an individual’s perceived capability to intend, be mindful, and absorb positive events through their lifespan to generate, expand, and maintain their happiness and positive affect. However, few earlier research studies have involved savoring in Thai people, in particular those in a healthcare setting. This study aims to examine the psychometric properties of a Thai version of the Savoring Beliefs Inventory (SBI) (Bryant, 2003). Participants were 120 older adult cancer patients and 120 family caregivers. Instruments were the Thai version of the Savoring Beliefs Inventory, Life Satisfaction Scale, and Positive Affect Scale. Data analysis included an assessment of internal consistency, confirmatory factor analysis, and correlational analysis. Findings revealed that the SBI-Thai version showed acceptable internal consistency with a Cronbach’s Alpha coefficient of .91 (for the patients) and .81 (for the caregivers). Using Confirmatory Factor Analysis (CFA), the three-factor model of the SBI-Thai version demonstrated a good fit for both older adult cancer patients and their family caregivers (χ² = 1.03, df = 1, p = .309, RMSEA = 0.017, χ²/df = 1.03, TLI = 0.998, CFI = 0.999, GFI = 0.994 and χ² = 1.12, df = 1, p = .289, RMSEA = 0.032, χ2/df = 1.12, TLI = 0.993, CFI = 0.998, GFI = 0.993, respectively). In addition, the SBI-Thai version was moderately associated with life satisfaction and positive affect constructs. Implications are discussed for using the SBI-Thai version in Thai people, especially those who are in a healthcare setting.
