The present study investigated the possibility of reducing length of psychosocial scales, while maintaining validity, using easily manageable techniques. Data were collected 2003–2004 in a Swedish general population; n = 1007, ages 45–69, 50% women. Eight psychosocial scales were reduced from 6–20 to 3–7 items maintaining Cronbach’s alpha >0.7 and correlation coefficients between full and reduced scales > 0.85. Relationships to biomarkers for inflammation, self-rated health and 8-year incidence of coronary heart disease showed no difference between full and reduced scales. It was possible, using these easily manageable methods, to reduce scale length without threatening validity for use in population surveys.

本研究调查了使用易于管理的技术在保持有效性的同时减少社会心理量表长度的可能性。数据收集于2003-2004年瑞典的一般人群中；n = 1007，年龄45-69岁，女性占50％。八个心理社会量表从6–20减少到3–7，保持Cronbach's alpha> 0.7，而满刻度和缩减量表之间的相关系数> 0.85。与炎症，自我评估的健康状况和8年的冠心病发病率等生物标志物的关系显示，在满刻度和缩小刻度之间没有差异。使用这些易于管理的方法，可以减少量表的长度，而不会威胁用于人口调查的有效性。
