- Step 3 (final item selection and psychometric evaluation): Patients and family members complete the FQOL questionnaire developed in previous steps and other questionnaires with proven reliability and validity at baseline. Other questionnaires include the SF-36 (general QOL survey that is used widely in general population samples and patients, including cancer patients), the FACT-G for patients (instrument used to assess health-related QOL in cancer patients), with the version of the FACT-G modified by Northouse for the family member, the Family Interaction and Emotional Well-Being subscales (to examine family interaction and family emotional support of cancer families) of the Beach Center Family Quality of Life Scale (FQOL measure for families with a disabled child), the Balanced Cohesion subscale (to examine family interaction of cancer families) of the FACES IV (that assesses balanced and unbalanced family cohesion and family flexibility in general population), and the Family Communication Scale (a general survey used to assess family communication in the general population). Patients and family members complete the FQOL again 2 weeks after the initial assessment.
