This study developed and validated the Exercise Behavioral Inconsistency Scale (ExBIS), which measures four facets as a profile rather than a summative trait\u2014intention level (IL), intention-action gap (IAG), emotional dissonance (ED), and internal rationalization (IR). Adults in T\u00fcrkiye (N = 594; 57.9% male; Mage = 21.02 years) completed a 20-item Turkish pool, split into exploratory and confirmatory analyses (n = 297 each); 5 items were removed, yielding 15 items. Parallel analysis and the minimum average partial test supported four factors explaining 67.1% of variance (loadings 0.56\u20130.96). Confirmatory analysis replicated the structure, \u03c72(84) = 187.90, CFI = 0.954, RMSEA = 0.065, SRMR = 0.057, outperforming simpler alternatives. Neither a second-order nor a bifactor model supported a general factor (ECV = 0.37, \u03c9H = 0.30), so scores form a four-facet profile rather than a total, clustering weakly into IL\/ED and IAG\/IR. The McDonald\u2019s omega was 0.78\u20130.90, and full scalar invariance held across gender and exercise-frequency groups. Subscales discriminated frequency groups as hypothesized (\u03c92 = 0.031\u20130.081). These cross-sectional data come from a young Turkish convenience sample surveyed in one language, so replication is required.<\/jats:p>","DOI":"10.3390\/bs16081308","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T01:43:27Z","timestamp":1785721407000},"page":"1308","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Development and Initial Validation of the Exercise Behavioral Inconsistency Scale (ExBIS): Factor Structure, Reliability, Measurement Invariance, and Known-Groups Validity"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3149-6630","authenticated-orcid":false,"given":"Bekir Erhan","family":"Orhan","sequence":"first","affiliation":[{"name":"Faculty of Sports Sciences, Istanbul Ayd\u0131n University, Istanbul 34295, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1016\/0749-5978(91)90020-T","article-title":"The theory of planned behavior","volume":"50","author":"Ajzen","year":"1991","journal-title":"Organizational Behavior and Human Decision Processes"},{"key":"ref_2","unstructured":"American Educational Research Association, American Psychological Association, and National Council on Measurement in Education (2014).
