死亡态度描绘量表应用于中国大学生的信效度分析

  目的   评价死亡态度描绘量表(修订)(death attitude profile-revised, DAP-R)中文版应用于中国大学生群体的死亡态度测量的信度和效度。   方法   利用中文版DAP-R量表对合肥7所高校561名在校大学生进行调查。采用Cronbach'sα系数和Spearman-Brown折半系数评价量表信度, 通过计算各条目与所在维度、维度与量表总分的Pearson相关系数评价内容效度, 运用Kaiser正常化最优斜交主成分因子分析评价结构效度。   结果   中文版DAP-R量表Cronbach'sα系数为0.868, Spearman-Brown折半系数为0.835。各条目与所在维度Pearson相关系数为0.554~0.828(均有P < 0.001);除自然接受, 余下4个维度与总分的Pearson相关系数为0.630~0.792(均有P < 0.001)。因子分析提取5个因子, 且所有条目归类的因子与DAP-R量表原所属维度一致, 累计方差贡献率达55.906%。   结论   DAP-R中文版量表应用于中国大学生具有较好的信、效度。

Analysis on the reliability and validity of Chinese version death attitude profile-revised (DAP-R) for Chinese college students

  Objective   To evaluate the reliability and validity of Chinese version death attitude profile-revised(DAP-R) scale among Chinese college students.   Methods   DAP-R scale was used to investigate 561 college students from 7 colleges and universities in Hefei. Cronbach's α coefficient and Spearman-Brown spit-half coefficient was used to evaluate the reliability of the scale. The Pearson correlation coefficients were calculated to evaluate the content validity. Factor analysis was performed to evaluate the construct validity.   Results   The Cronbach's α coefficient of the whole scale was 0.868, and the Spearman-Brown spit-half Coefficient was 0.835. The Pearson correlation coefficients was from 0.554 to 0.828(all P < 0.001). In addition to natural acceptance, the Pearson correlation coefficients between dimensions and the total score were 0.630-0.792(allP < 0.001). 5 factors extracted form factor analysis were basically the theoretical conception of the DAP-R scale, and the cumulative variance contribution rate was 55.906%.   Conclusions   The Chinses version DAP-R scale is valid and reliable for assessing the death attitude of college students.
