title: The psychometric properties of the Barkin Index of Maternal Functioning.
abstract: OBJECTIVE
  To evaluate the psychometric properties of the Barkin Index of Maternal Functioning (BIMF).
  
  
  METHODS
  Principal component factor rotation was used to conduct an exploratory factor analysis of the BIMF to determine if more concise versions exist.
  
  
  METHODS
  Patients were recruited from a large, urban medical center in the Northeast.
  
  
  METHODS
  The BIMF was administered at an initial home visit along with several other self-report and clinical assessments to women who scored ≥ 10 on the Edinburgh Postnatal Depression Scale during the 4- to 6-week postpartum period.
  
  
  METHODS
  The BIMF was administered between October 2008 and September 2010. The distribution of BIMF item responses was examined along with interitem correlations. To establish construct validity, correlation coefficients were produced for the BIMF in relation to several other variables or assessments. A factor analysis was performed using principal component factor rotation.
  
  
  RESULTS
  The factor analysis revealed a two-factor solution. The items that loaded on factor 1 gauged the mother's perception of her own competency in the maternal role and the items that made up factor 2 focused on the mother's needs. Items related to judgment from others and anxiety did not load on either factor.
  
  
  CONCLUSIONS
  The BIMF may be administered in its 18-item version, as two separate subscales, or in its original 20-item format. A clinical threshold should be developed to facilitate accurate identification of mothers who are struggling with functioning during the postpartum period.
