Development of a brief version of the Pathological Narcissism Inventory.

ABSTRACT: With theoretical and empirical interest in narcissism growing, there is a need for brief measures of pathological narcissism that can be used more practically while assessing the construct comprehensively. Data from four samples (total N = 3,851) collected across two separate research groups and representing undergraduate, community, and clinical populations were used to establish the reliability, validity, and utility of the Brief-Pathological Narcissism Inventory (B-PNI). Item response theory and confirmatory factor analyses were used to determine the best-performing 28 items from the original PNI and ensure that the B-PNI exhibited a factor structure consistent with the original PNI. Items were retained for all seven pathological narcissism facet scales. Additional results also support the criterion validity of the B-PNI, suggesting that it can be used in place of the original PNI to assess the various facets of pathological narcissism effectively and without loss of information, which may enhance the ability of researchers to investigate pathological narcissism in future work.

Project description:BackgroundKnee osteoarthritis (KOA) primarily presents with symptoms of pain and compromised functionality. Pain is a subjective manifestation that necessitates the employment of reliable evaluation tools for practical assessment, thereby enabling the formulation of appropriate interventional strategies. The Brief Pain Inventory (BPI) is a widely utilized questionnaire for evaluating the status of chronic pain. The purpose of the present study is to translate the short form of BPI into Chinese version (BPI-CV) and conduct cross-cultural adaptation to evaluate the psychometric characteristics of BPI-CV in KOA patients.MethodsBPI-CV was translated and cross-culturally adapted according to internationally recognized guidelines. A cohort comprising 150 patients diagnosed with KOA successfully completed the demographic questionnaire, BPI-CV, Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and the EuroQoL Group's five-dimension questionnaire (EQ-5D). Internal consistency and test-retest analysis were used to evaluate the reliability. The internal consistency of the scale items was evaluated by calculating the Cronbach's α value (> 0.7). We chose to employ two scales commonly used in the evaluation of KOA patients: the disease-specific WOMAC scale and the universal EQ-5D scale. Construct validity was determined through Pearson correlation analysis, comparing BPI scores with those obtained from the WOMAC and EQ-5D scales. Exploratory factor analysis was used to structural validity.ResultsThe BPI-CV was well accepted with no ceiling or floor effect. Cronbach's α for assessing internal consistency was 0.894. Test-retest reliability was excellent with an ICC of 0.852 (95%CI 0.785-0.905). The BPI-CV showed moderate to strong correlations with the pain dimension (r = 0.496-0.860) and the functional interference dimension (r = 0.517-0.712) of the WOMAC and the EQ-5D (r = 0.527-0.743). Three factors resulted using exploratory factor analysis: pain severity, activity interference, and emotional interference, accounting for 79.0% of the total variance. Standard error of measurement was 0.539.ConclusionBPI-CV has good feasibility, reliability, and validity. It can be recommended for KOA patients in mainland China.
