Psychometric Properties of the Interpersonal Style Questionnaire (ISQ) and the Patterns of Thinking Survey (POTS)

Self-regulation is a complex concept that includes multiple interacting factors, and it is studied across multiple fields of psychological research. Various theoretical models have been offered to explain this concept. Although models differ in their definitions of self-regulation, all consistently posit that it consists of emotional, behavioral, interpersonal, and cognitive domains. The current study examined the psychometric properties of two novel measures – 1) McVay and Stinson Interpersonal Style Questionnaire (ISQ) and 2) Stinson and McVay Patterns of Thinking Survey (POTS) – utilizing both a clinical and nonclinical sample. Results indicate that these measures are comprised of three factors across both samples. Validity was analyzed by using already existing measures of emotion regulation and associated psychiatric symptoms. Results from the validity analyses were examined from a theoretical perspective and highlight the complexity and interconnectedness of self-dysregulation as a concept, in addition to the domains it is comprised of. Although there were limitations that are specific to each sample, this study on self-dysregulation provides preliminary results as to the structure, validity, and internal consistency of two novel instruments.
