SOLACE Spectrum: A Personality Assessment for Personal Growth in Therapy.

Personality assessment has long been recognized as a valuable tool for understanding individual differences with implications for self-understanding and growth-related processes. Building on the development of the Personality Spectrum Analysis (PSA), the present study evaluated the SOLACE Spectrum, a revised and expanded measure designed to provide a reliable and accessible framework for understanding personality in therapeutic and relational contexts. Data were collected from 1021 adults through online administration, and exploratory factor analysis revealed six components: Stability, Optimism, Leadership, Achievement, Compassion, and Extroversion. The instrument demonstrated strong internal consistency (α = 0.91) and robust test-retest reliability (0.851-0.922), indicating stability over time. Findings support the SOLACE Spectrum as a psychometrically sound measure that can inform understanding of personality traits, relationship processes, and personal growth processes. Its application may assist professionals in therapy, counseling, and educational or organizational settings by providing descriptive feedback on personality dimensions, highlighting areas of strength, and identifying potential areas for reflection and personal insight.
