The How I Think (HIT) Questionnaire assesses self-serving cognitive distortions to aid in psychological evaluation and treatment. The questionnaire, developed by Dr. Alvaro Q. Barriga, Dr. John C. Gibbs, and Granville Bud Potter, measures four categories of thinking errors: self-centeredness, blaming others, minimizing/mislabeling, and assuming the worst. It is a 54-item measure designed for group or individual administration, requiring only a fourth-grade reading level and taking 5 to 15 minutes to complete. The accompanying 44-page manual provides detailed instructions for administration, scoring, interpretation, and discusses the questionnaire's theoretical basis, development, reliability, and validity.

The HIT questionnaire is presented as a practical tool for psychological assessment and treatment planning, particularly for identifying cognitive distortions. Its design emphasizes ease of use with a low reading level requirement and brief administration time, making it accessible for various clinical and program evaluation purposes. The accompanying manual provides a comprehensive guide to its application, supported by information on its reliability and validity. The tool is intended for professionals involved in assessment and therapeutic interventions.
