The validity of the family relationships index as a screening tool for psychological risk in families of cancer patients.

摘要

The Family Relationships Inventory (FRI) has been proposed as a measure of psychological risk however its validity has only been tested in one cross-sectional study against another measure of family functioning where patients had less than six months to live. The current study presented longitudinal data on the validity of the FRI in identifying family dysfunction, and clinical levels of depression and anxiety in 48 families where the patient had been recently diagnosed. Over the three phases, the FRI identified all families at risk of family dysfunction, 88% or more families with one or more members with clinical depression and 78% or more with a member with clinical levels of anxiety. The FRI was also far more sensitive in identifying families with a member with clinical levels of depression and anxiety than the General Functioning (FAD-GF) scale of the Family Assessment Device. Although other measures of screening adequacy (such as specificity), suggested that the FRI identified too many false positives, the higher sensitivity of the FRI makes it preferable to the FAD-GF as a screening measure for families at risk of a poor psychological outcome in the oncology setting. However, because of the FRI's poor specificity, further follow-up of those families that are identified as being at some risk of a poor psychological outcome should be undertaken before referral to a mental health professional is warranted.
