Building a Scale for Obsessive-Compulsive Personality Disorder (OCPD) Among Students at the University of Mosul

The current research aimed to develop a scale for Obsessive-Compulsive Personality Disorder (OCPD) among students at the University of Mosul, The study population consisted of students at the University of Mosul during the academic year 2023/2024, totalling (44,333) students distributed across (24) colleges. To select the research sample, the researchers employed the stratified random sampling method, selecting (1800) students from ten colleges, distributed across five scientific disciplines and five humanities disciplines.
The researchers developed the scale in its initial form, which consisted of (56) items distributed across eight criteria: (preoccupation with details, organization, and order; perfectionism; excessive devotion to work; rigid conscience and morals; hoarding; self-centred approach to work; frugality in spending; rigidity and stubbornness). The items were presented with a five-point Likert scale (Always applies to me - Often applies to me - Sometimes applies to me - Rarely applies to me - Never applies to me).
The validity of the tool was established through face validity by presenting it to (33) experts from Iraqi universities. Additionally, construct validity and item discrimination were calculated, leading to the removal of (10) non-discriminatory items. Consequently, the final version of the scale consisted of (46) items. The reliability of the scale was assessed using the test-retest method, yielding a reliability coefficient of (0.83), and Cronbachs Alpha method, which resulted in a value of (0.86). The results concluded with the successful development of a scale for Obsessive-Compulsive Personality Disorder among students at the University of Mosul, ready for application.
