What type of assessment involves questionnaires completed to determine the degrees of various personality traits?

Self-report inventories are assessments wherein individuals complete questionnaires designed to evaluate the presence and intensity of various personality traits. These instruments allow respondents to convey their thoughts, feelings, and behaviors, which are then analyzed to provide insights into their personality characteristics.

The structured format of self-report inventories enables researchers and psychologists to quantify traits across a range of factors, facilitating a systematic understanding of personality. Such assessments can cover a myriad of dimensions, including but not limited to extraversion, agreeableness, conscientiousness, and emotional stability, making them a fundamental tool in both clinical and organizational settings. The reliance on the individual's self-knowledge and introspection in self-reporting differentiates this method from other forms of assessment, providing a unique perspective on personality.

In contrast, interviews involve direct interaction and discussion between a trained individual and the respondent, which might yield qualitative insights but lack the standardized measurement that questionnaires provide. Observations focus on assessing behavior in real-time situations and may miss internal thought processes or self-perceptions. Performance evaluations assess how well an individual performs certain tasks, typically in a work or educational context, without necessarily analyzing underlying personality traits.

Thus, self-report inventories stand out as a robust method specifically aimed at measuring personality traits through direct self-assessment.
