title: [Design and validation of a questionnaire for psychosocial nursing diagnosis in Primary Care].
abstract: OBJECTIVE
  To develop a valid, reliable and easy-to-use questionnaire for a psychosocial nursing diagnosis.
  
  
  METHODS
  The study was performed in two phases: first phase, questionnaire design and construction; second phase, validity and reliability tests. A bank of items was constructed using the NANDA classification as a theoretical framework. Each item was assigned a Likert scale or dichotomous response. The combination of responses to the items constituted the diagnostic rules to assign up to 28 labels. A group of experts carried out the validity test for content. Other validated scales were used as reference standards for the criterion validity tests. Forty-five nurses provided the questionnaire to the patients on three separate occasions over a period of three weeks, and the other validated scales only once to 188 randomly selected patients in Primary Care centres in Tenerife (Spain).
  
  
  RESULTS
  Validity tests for construct confirmed the six dimensions of the questionnaire with 91% of total variance explained. Validity tests for criterion showed a specificity of 66%-100%, and showed high correlations with the reference scales when the questionnaire was assigning nursing diagnoses. Reliability tests showed agreement of 56%-91% (P<.001), and a 93% internal consistency. The Questionnaire for Psychosocial Nursing Diagnosis was called CdePS, and included 61 items.
  
  
  CONCLUSIONS
  The CdePS is a valid, reliable and easy-to-use tool in Primary Care centres to improve the assigning of a psychosocial nursing diagnosis.
