Analysis

The PCS consists of a series of statements to which participants are asked to respond using a Likert scale, usually 5 or 7 points, where the scale anchors may be defined as “Strongly Disagree” and “Strongly Agree.” These statements relate to the individual’s self-perception regarding their ability to perform specific activities or achieve goals.

Purpose

The purpose of the PCS is to assess an individual’s self-esteem and self-confidence in specific domains. It can be used for:
Educational Assessment: Determining students’ or learners’ self-perception regarding their academic abilities.
Sports Psychology: Evaluating athletes’ self-esteem in relation to their ability in athletic activities.
Psychological Research: Studying the relationship between self-esteem and other psychological or social variables.
Workplace Assessment: Understanding employees’ self-confidence in relation to their professional performance.

Scoring

The scoring of the PCS is carried out by analyzing the responses given to each statement. Each statement is rated according to the Likert scale used, and the scores are summed to yield a total score for perceived competence. Higher scores indicate greater perceived competence, while lower scores indicate lower self-esteem regarding ability.
The reliability and validity of the questionnaire are evaluated using statistical methods such as internal consistency (Cronbach’s Alpha) and factor analysis. Ensuring the reliability and validity of the tool is critical for the accurate measurement of perceived competence.
