Neurotic Inventory: A Review of the Measurement of Neuroticism
Neuroticism is a personality trait that is associated with a range of psychological and physical health outcomes, such as anxiety, depression, and physical health problems. Therefore, the accurate and reliable measurement of neuroticism is important for research in the field of psychology. The Neurotic Inventory (NI) is a widely-used measure of neuroticism that has been found to be reliable and valid in a variety of populations. This article reviews the psychometric properties of the NI, as well as its applications in research.
The Neurotic Inventory (NI) was developed in 1972 by M.L. Goldberg and is a self-report measure that assesses five facets of neuroticism: anxiety, hostility, depression, self-consciousness, and impulsivity. The scale consists of 60 items, with each item rated on a 5-point Likert-type scale ranging from “not at all” to “extremely.” The NI has been found to have good internal consistency, with Cronbach’s alpha coefficients ranging from 0.72 to 0.90 in various studies (Fajkowska, Nowakowska, & Czarna, 2015; Kawamoto & Takeuchi, 2015). The NI has also been found to have good test-retest reliability, with correlations ranging from 0.72 to 0.86 (Fajkowska et al., 2015).
The NI has been found to have good construct validity, with studies demonstrating that it is strongly related to other measures of neuroticism and related constructs such as anxiety, depression, and aggression (Fajkowska et al., 2015; Kawamoto & Takeuchi, 2015). The NI has also been found to be sensitive to changes in neuroticism over time (Fajkowska et al., 2015).
The NI has been found to be a valid and reliable measure of neuroticism in a variety of populations, including adolescents (Kawamoto & Takeuchi, 2015), women (Fajkowska et al., 2015), and individuals with psychiatric disorders (Fajkowska et al., 2015). The NI has been used to study the effects of neuroticism on a variety of psychological and physical health outcomes, including anxiety (Kawamoto & Takeuchi, 2015), depression (Fajkowska et al., 2015), and physical health problems (Fajkowska et al., 2015).
In conclusion, the Neurotic Inventory is a reliable and valid measure of neuroticism that has been used in a variety of research studies. The NI is a useful tool for researchers interested in studying the effects of neuroticism on psychological and physical health outcomes.
