Spanish Validation of the “Life Snapshot Inventory”

Abstract

Introduction: The Life Snapshot Inventory (LSI) is a self-report instrument to measure the meaningful vital, personal, and social directions. It was created in the Functional Analytic Psychotherapy as a continuous evaluation of vital changes in areas of life (family, work, love, spirituality, sexuality, health, etc.). Objective: The aim was to validate its psychometric characteristics for the first time. Method: This study involved 530 participants (average age 33 years), in a Spanish sample. The questionnaire has been compared with the Rosenberg Self-Esteem Scale (RSES) to obtain convergent validity. Results: The results showed a high internal consistency (α=.93) and a correlation of .61, both statistically significant. The factorial analysis showed only one factor (43.56% of variance). In addition, it was sensitive to changes due to interventions, and made it possible to differentiate those people with vital problems. Conclusion: This questionnaire could be a helpful measure for healthcare and clinical contexts.
