title: [Reliability and construct validity of an instrument to asses the Self-perception of Family Health Status].
abstract: BACKGROUND
  Family health determines and it is determined by family´s capacity to function effectively as a biosocial unit in a given culture and society. The main of study has been to test reliability and construct validity of an instrument to asses the Self-perception of Family Health Status.
  
  
  METHODS
  We validated its content by an on-line Dephi panel with experts. We surveyed 258 families in them homes or in primary health centres from Seville, Spain. We administered the instrument that has five Likert scales: Family climate, Family integrity, Family functioning, and Family resistance. We tested reliability by Cronbach Alpha and construct validity by exploratory factor analysis.
  
  
  RESULTS
  The five scales obtained values α between 0.73 for the Family Climate and 0.89 for Family Integrity. They showed evidence of one-dimensional interpretation after factor analysis, a) all items got weights r>0.30 in first factor before rotations, b) the first factor explained a significant proportion of variance before rotations, and c) the total variance explained by the main factors extracted was greater than 50%.
  
  
  CONCLUSIONS
  The scales showed their reliability and validity. They could be employed to assess the self-perception of family health status.
