Generalized perceived powerlessness is an important psychosocial construct that determines a wide range of health behaviors and outcomes. This study has two aims: (1) examine the structure of the newly developed perceived powerlessness scale using exploratory and confirmatory factor analyses and (2) assess the scale's invariance across key demographic variables using multi-group confirmatory factor analysis among a random household sample of African American and White youth (aged 15-24 years) residing in Baltimore, MD. Our study results demonstrated that the powerlessness scale is valid among a demographically diverse sample of urban youth, showing promise for use in future health behavior and outcome studies.
普遍感知到的无力感是一种重要的社会心理结构，它决定了广泛的健康行为和结果。本研究有两个目的：（1）使用探索性和验证性因素分析来检验新开发的无力感量表的结构，以及（2）在居住在马里兰州巴尔的摩的非裔美国人和白人青年（15 - 24岁）的随机家庭样本中，使用多组验证性因素分析来评估该量表在关键人口统计学变量上的不变性。我们的研究结果表明，无力感量表在城市青年的不同人口统计学样本中是有效的，这显示出其在未来健康行为和结果研究中的应用前景。
