Exploratory and confirmatory factor analyses and invariance assessment of the perceived powerlessness scale among youth in Baltimore.

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.
