Abstract

BackgroundThe Mental Health Optimization Checklist (MHOC) is a proposed measure which utilizes the theory of optimization science to improve mental health outcomes. Psychopathology is typically viewed dichotomously (i.e., does or does not have a disorder) or through cut-off criterion (i.e., 4 out of 5 symptoms, total scores), whereas optimization views psychopathology on a continuum on which patients can optimize factors impacting their mental health. Optimization theory is important for reducing stigma around mental health treatment and the MHOC offers itself as an informative psycho-diagnostic tool. Methods An undergraduate student sample (n = 682) completed the MHOC and the Symptom Checklist 90 Revised (SCL-90-R) via Qualtrics. This study evaluated the content and structure of the MHOC and compared it to a traditional measure of psychopathology, the SCL-90-R (Derogatis & Savitz, 1999). Specifically, researchers (1) examined the LPOC’s internal consistency, (2) examined its validity, (3) conducted item analyses in order to determine how the internal consistency and validity of the MHOC could be improved, and (4) conducted an item- level factor analysis. Results The MHOC was found to have high internal consistency with a coefficient alpha of .96. Convergent validity between the SCL90-R and the LPOC was moderate, r(680) = -.40, p < .001, 95% CI [-.46, -.33]. In item analyses, all values of alpha-if-item-deleted were .96. The scree test, the MAP test, and parallel analysis suggested three to five factors, and four factors were extracted and interpreted as Emotional and Cognitive Resiliency, Relationships, Habits, and Self- Discipline. Conclusions The MHOC was evaluated for its utility as a clinical measure to identify psychopathology. It was found to have good reliability and validity, and it is expected to be an effective tool for measuring psychopathology using an optimization model.
