Abstract

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; = 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.

摘要

本研究探讨了运用易于操作的技术在保持效度的同时缩短心理社会量表长度的可能性。2003年至2004年在瑞典普通人群中收集数据;样本量n = 1007,年龄在45至69岁之间,女性占50%。八个心理社会量表从6至20项缩减至3至7项,同时保持克朗巴哈系数α>0.7以及完整量表与缩减后量表之间的相关系数>0.85。与炎症生物标志物、自评健康状况以及冠心病8年发病率之间的关系在完整量表和缩减后量表之间未显示出差异。使用这些易于操作的方法,可以缩短量表长度,且不会威胁到其在人群调查中的效度。
