Development and testing of a family nursing scale.

A methodological study was conducted to test the psychometric properties of the Family Functioning, Health, and Social Support (FAFHES) Instrument to be used with families of heart patients. A total of 109 initial items were developed based on knowledge generated by three Finnish academic dissertations concerning family functioning, health, and social support provided by nurses. Data were collected from family members of 161 heart patients. Principal component analysis was performed in each of three total scales: family functioning, family health, and social support. The scales had acceptable reliability (alpha coefficients ranged from .73 to .95). Internal consistency reliability and content validity of the FAFHES have initial support. Results obtained from this study support that this instrument is ready for use in research in which the investigator wishes to measure social support associated with family functioning and the health of families of heart patients.
