There are currently no specific tools available to assess self-efficacy among Vietnamese individuals with colorectal cancer (CRC) post-surgery. Translating and evaluating the psychometric properties of the New General Self-Efficacy Scale (NGSE) for use in the Vietnamese population could help address this gap.
This study aimed to evaluate the psychometric properties of the Vietnamese version of the NGSE scale.
A cross-sectional study was conducted. The sample consisted of 120 individuals aged 20-59 with CRC post-surgery, recruited through a multi-stage sampling technique from three hospitals in Vietnam. The scale was translated into Vietnamese using Brislin's technique. Content validity was assessed using the Content Validity Index for item (I-CVI) and for scale (S-CVI). Construct validity was examined through confirmatory factor analysis (CFA), and reliability was measured using Cronbach's α coefficients.
The findings showed an I-CVI of 1.00 and an S-CVI of 1.00, indicating excellent content validity. The Cronbach's α for the NGSE was 0.95, indicating excellent internal consistency. CFA results showed that all eight items fit well within a unidimensional structure (χ = 48.936, >0.05, df = 24, χ/df = 2.04, RMSEA = 0.078, CFI = 0.979, TLI = 0.971, SRMR = 0.023). Factor loadings for each item ranged from 0.798 to 0.901.
The results suggest that the NGSE scale demonstrates good psychometric properties as applied to the Vietnamese individuals examined in this study. This instrument can be regularly utilized in clinical settings to identify key concerns in colorectal cancer patients' care and facilitate appropriate nursing interventions to enhance self-efficacy in this population effectively.
目前尚无专门工具可用于评估越南结直肠癌（CRC）术后患者的自我效能感。翻译并评估新的一般自我效能量表（NGSE）在越南人群中的心理测量特性有助于填补这一空白。
本研究旨在评估越南版NGSE量表的心理测量特性。
进行了一项横断面研究。样本包括120名年龄在20 - 59岁之间的CRC术后患者，通过多阶段抽样技术从越南的三家医院招募。采用Brislin技术将量表翻译成越南语。使用项目内容效度指数（I-CVI）和量表内容效度指数（S-CVI）评估内容效度。通过验证性因子分析（CFA）检验结构效度，并使用Cronbach's α系数测量信度。
结果显示I-CVI为1.00，S-CVI为1.00，表明内容效度极佳。NGSE的Cronbach's α为0.95，表明内部一致性极佳。CFA结果显示，所有八个项目在单维结构中拟合良好（χ = 48.936，>0.0５，df = 24，χ/df = 2.04，RMSEA = 0.078，CFI = 0.979，TLI = 0.971，SRMR = 0.023）。每个项目的因子载荷范围为0.798至0.901。
结果表明，NGSE量表应用于本研究中的越南个体时显示出良好的心 理测量特性。该工具可在临床环境中定期使用，以识别结直肠癌患者护理中的关键问题，并促进适当的护理干预措施，以有效提高该人群的自我效能感。
