title: [Development and evaluation of the reliability and validity of an empowerment scale for health promotion volunteers].
abstract: OBJECTIVE
  This qualitative and quantitative research was conducted to develop an empowerment scale for health promotion volunteers (hereinafter referred to as the ESFHPV), key persons responsible for creating healthy communities.
  
  
  METHODS
  A focus group interview was conducted with four groups of health promotion volunteers from two cities in S Public Health Center of N Prefecture. A qualitative analysis was employed and a 32-item draft scale was created. The reliability and validity of this scale were then evaluated using quantitative methods. A questionnaire survey was conducted in 2009 for all 660 health promotion volunteers across the 2 cities. Of 401 respondents (response rate, 60.8%), 356 (53.9%) provided valid responses and were thus included in the analysis.
  
  
  RESULTS
  1) Internal consistency was confirmed by item-total correlation analysis (I-T analysis), assessment of Cronbach's coefficient alpha for all except one item and good-poor analysis (G-P analysis). Four items were excluded from the 32-item draft scale because of correlation coefficients more than 0.7, leaving 28 items for analysis. 2) Based on the results obtained from the factor analysis performed on the 28 provisional empowerment questions, 28 items were chosen for inclusion in the ESFHPV. These items consisted of four sub-scales, namely 'activity for healthy community' (10 items), 'intention for solving health problems of the community' (10 items), 'democratic organization activity' (four items) and 'growth as individual health promotion volunteers' (four items). 3) The Cronbach's coefficient alpha for the ESFHPV and its four sub-scales were 0.93, 0.88, 0.89, 0.84 and 0.79 respectively. The coefficients of I-T analysis were between 0.33 and 0.69. 4) The health promotion volunteers who attended other community activities demonstrated significantly high scores for the ESFHPV and the four sub-scales. Persons who were above 60 years, had a longer duration of activity as a health promotion volunteer and were housewives showed significantly high scores on the first sub-scale, 'growth as individual health promotion volunteers'
  
  
  CONCLUSIONS
  To measure the empowerment levels of health promotion volunteers, a 28-item scale was developed and its reliability and validity were confirmed. Health promotion volunteers as well as the public health nurses who assist them can use this scale to assess the empowerment levels of other health promotion volunteers.
