This chapter explores the assessment of personality—the enduring patterns of thinking, feeling, relating, and behaving that shape how individuals experience themselves and the world around them. While psychiatric symptoms may fluctuate across time, personality provides the deeper framework through which those experiences are interpreted and expressed.
Personality assessment seeks to understand the characteristic ways people perceive reality, regulate emotions, form relationships, respond to stress, and construct their identities. It moves beyond diagnosis alone, asking not simply what disorder is present, but who the person is.
The chapter examines the major approaches to personality assessment, including clinical interviews, behavioural observation, self-report measures, structured personality inventories, and projective techniques. Each method provides a different perspective on the individual’s psychological functioning, strengths, vulnerabilities, and interpersonal style.
A central theme is that personality exists along dimensions rather than rigid categories. Traits such as emotional stability, conscientiousness, openness, agreeableness, and extraversion vary across individuals and influence how people adapt to life’s challenges. Personality pathology often reflects extreme, inflexible, or maladaptive expressions of otherwise normal traits.
The chapter also highlights the importance of understanding personality in clinical practice. Personality influences symptom presentation, treatment engagement, therapeutic alliance, coping strategies, resilience, and long-term outcomes. Two individuals with the same diagnosis may have profoundly different experiences because of differences in personality structure.
Importantly, personality assessment seeks not only to identify dysfunction but also to uncover strengths. Adaptive traits, coping capacities, values, motivations, and relational resources often become crucial foundations for recovery and growth.
Ultimately, this chapter reminds us that effective psychiatry requires more than identifying illness. It requires understanding the unique psychological architecture of the person who carries it.
