The Personal Social Capital Scale 16 (PSCS-16) is a self-report measure used to assess social capital, as a social determinant of health. To guarantee validated measures of this construct, the psychometric properties of the Portuguese version of the PSCS-16 were studied.
The PSCS-16 comprises 16 items, organized in two scales: bonding and bridging social capital. A convenience sample of 280 participants was collected through an online survey. For construct validity, we used confirmatory factor analysis, and convergent and discriminant validity through the average variance extracted (AVE) and correlations. For reliability, we used: The Spearman-Brown split-half and the omega hierarchical coefficient. Correlations were made between the PSCS-16 and socio-demographic variables.
A first-order model depicting two oblique factors was supported, suggesting the use of the two scales. Evidence of convergent validity was achieved: acceptable AVE and associations between social capital and emotional self-disclosure. For discriminant validity, the AVE values surpassed the squared correlation between bonding and bridging, and associations with sexual health were found to be absent. Reliability was good. Additional correlations: A positive association between the education level and bridging social capital and participants with an immigrant status having more bridging social capital.
Preliminary findings support the Portuguese version of PSCS-16 as suitable to evaluate social capital. Contributions are highlighted: the need to study correlates of social capital, particularly crossing migrations, social capital and mental health; and confirming the structure found by measuring its invariance.
个人社会资本量表16（PSCS - 16）是一种用于评估社会资本的自评工具，社会资本是健康的一个社会决定因素。为确保对这一结构的有效测量，对PSCS - 16葡萄牙语版本的心理测量特性进行了研究。
PSCS - 16由16个项目组成，分为两个量表：联结型社会资本和桥接型社会资本。通过在线调查收集了280名参与者的便利样本。对于结构效度，我们使用验证性因子分析，并通过提取的平均方差（AVE）和相关性来检验聚合效度和区分效度。对于信度，我们使用：斯皮尔曼 - 布朗分半法和欧米伽层级系数。对PSCS - 16与社会人口学变量之间进行了相关性分析。
支持了一个描述两个斜交因子的一阶模型，表明两个量表均可使用。实现了聚合效度的证据：AVE可接受，且社会资本与情感自我表露之间存在关联。对于区分效度，AVE值超过了联结型和桥接型之间的平方相关性，且未发现与性健康的关联。信度良好。其他相关性：教育水平与桥接型社会资本呈正相关，具有移民身份的参与者拥有更多的桥接型社会资本。
初步研究结果支持PSCS - 16葡萄牙语版本适用于评估社会资本。强调了以下贡献：需要研究社会资本的相关因素，特别是跨境移民、社会资本与心理健康之间的关系；并通过测量其不变性来确认所发现的结构。
