In the research literature, various scholars prefer varied types of self-confidence measures. However, the literature reviewed revealed two commonly used measures namely self-report measures and online measures. Self-report measures, as suggested by the name, refers to measures of self-confidence whereby the participants answer questions regarding their own feelings, character, and emotions. They involve both cognitive and physical measures (Stankov, Kleitman, & Jackson, 2014). The Personal Evaluation Inventory (PEI) is among the most common self-report measures (Burns, Burns, & Ward, 2016). The PEI is a list of 54 questions answered using a 4-point Likert scale: strongly disagree, disagree, agree, & strongly agree. Whenever this kind of measurement is used to assess a person’s self-confidence, it essentially analyses their personality traits. On the other hand, online measures are often used to determine a person’s abilities (Burns, Burns, & Ward, 2016). Online measures tend to be performance-based. The online measures and self-report measures incorporate both behavioral and physiological aspects of an individual. For instance, the behavior of a person among other factors will determine their self-confidence.
Given a scenario where I need to apply one of the measures of self-confidence, I would use the common self-report measure known as the PEI. I would prefer this measure because it has been used in many past studies and proven successful as a measure of self-confidence. Furthermore, its use in the past also points to its validity and reliability (Alhoshan, 2019). Besides, compared to the behavioral measures whereby an observer will conclude on an individual’s behavior by watching them, I find self-reporting a more reliable source since it provides first-hand information. Sometimes observations may be elusive unless one engages with the individual to understand why they behave the way they do.
