Abstract
A total of 1,661 respondents contributed to the development of the , which includes 23 items across two subscales.
- The Psychological Insight Questionnaire features two subscales: Avoidance and Maladaptive Patterns Insights, and Goals and Adaptive Patterns Insights.
- Strong correlations were found between the Psychological Insight Questionnaire scores and the insight subscale of the Session Impacts Scale.
- Weak-to-moderate correlations were observed with the Mystical Experiences and Challenging Experiences Questionnaires.
- Scores on the Psychological Insight Questionnaire were moderately-to-strongly associated with reported increases in psychological flexibility and life satisfaction following a psychedelic experience.
- Incremental validity was demonstrated, showing that the questionnaire predicts unique changes in psychological flexibility and well-being beyond existing measures of mystical-type and challenging effects.
