Development and Initial Validation of the Perceived Scarcity Scale (PScS).

Though socio-economic status (SES) partially explains the experience of stress and health outcomes, most research to date has relied on a small number of traditional indicators that fail to capture the full domain of socioeconomic factors. The recent reconceptualization of perceived scarcity is proposed as a subjective indicator of SES when attempting to predict both stress and health outcomes. Although a conceptualization of perceived scarcity has been advanced, a psychometrically sound scale is needed to assess the utility and scientific import of this concept. No such scale exists. Therefore, the current paper describes the development, psychometric properties, and initial validation of the Perceived Scarcity Scale (PScS). Four studies using traditional scale development processes were employed to develop (Studies 1 and 2) and provide an initial validation (Studies 3 and 4) for the PScS. Results support the existing model of perceived scarcity and indicate that the measure is valid. Moreover, the scale predicted concurrent perceived stress, as well as longitudinal ratings of perceived stress, global health, quality of life, and symptoms of depression and anxiety. The development of the new scale provides clinicians and researchers with a brief, validated measure that can assess the level of perceived scarcity individuals currently experience.
