The Social Provisions Scale-10 item (SPS-10) is a shortened version of the Social Provisions Scale (Cutrona and Russell, 1987) validated in French (Échelle de provisions sociales) by Caron (1996). The Social Provisions Scale (SPS) originally consisted of six subscales to measure the availability of social support: emotional support or attachment, social integration, reassurance of worth, tangible help, orientation and opportunity for nurturance. Four items allowed measuring of each subscales, two formulated positively and two negatively for a total of 24 items. The SPS-10 retains five subscales, opportunity for nurturance was excluded and it only keeps the positively worded items, two items per dimension of support. The article presents its validation on a representative sample of 2433 people of the general population of the southwest region of Montreal. It has a strong concurrent validity with the original scale of 24 items (SPS) (r = 0.930). All its items are highly correlated with total scores and its internal consistency is excellent. The alpha for the global scale is 0.880 and the alphas for the five subscales ranged from 0.528 to 0.690. Its construct validity is also preserved. The SPS-10 has an independence of its dimensions with moderate correlations between the subscales ranging between 0.469 and 0.632 and its five subscales are more strongly related to the support global score (r minimum = 0.755 p <0.001 and r maximum = 0.835), indicating that they are also indicators of the availability of social provisions. An exploratory factor analysis allows finding almost the same factors structure than the French version of SPS. The SPS-10 explains 14.1% of the variance in psychological distress and retains 95% of the predictive power of the SPS-24 items and all its subscales are negatively correlated with psychological distress. It also explains 25.4% of the variance in quality of life and its predictive power is equivalent to the SPS-24 items and all its subscales are positively correlated to QOL. The analyses suggest that the SPS-10 is a reliable and valid instrument for measuring the availability of social support with an administration time reduced by half. It is an excellent choice for epidemiological surveys.
社会支持量表10项版（SPS - 10）是社会支持量表（Cutrona和Russell，1987年）的简化版本，由Caron（1996年）用法语（社会支持量表）进行了验证。社会支持量表（SPS）最初由六个子量表组成，用于衡量社会支持的可得性：情感支持或依恋、社会融合、价值肯定、实际帮助、指导和养育机会。每个子量表有四个项目进行测量，两个为正向表述，两个为负向表述，共24个项目。SPS - 10保留了五个子量表，排除了养育机会子量表，并且只保留了正向表述的项目，每个支持维度两个项目。本文展示了其在蒙特利尔西南地区2433名普通人群代表性样本上的验证情况。它与24项的原始量表（SPS）具有很强的同时效度（r = 0.930）。其所有项目与总分高度相关，内部一致性极佳。总量表的阿尔法系数为0.880，五个子量表的阿尔法系数在0.528至0.690之间。其结构效度也得以保留。SPS - 10各维度相互独立，子量表之间的相关性适中，在0.469至0.632之间，其五个子量表与支持总分的相关性更强（r最小值 = 0.755，p <0.001；r最大值 = 0.835），表明它们也是社会支持可得性的指标。探索性因素分析发现其因素结构与法语版SPS几乎相同。SPS - 10解释了心理困扰方差的14.1%，保留了SPS - 24项量表95%的预测能力，且其所有子量表与心理困扰呈负相关。它还解释了生活质量方差的25.4%，其预测能力与SPS - 24项量表相当，且所有子量表与生活质量呈正相关。分析表明，SPS - 10是一种可靠且有效的测量社会支持可得性的工具，施测时间减少了一半。它是流行病学调查的绝佳选择。
