Conclusion
On basis of our results we conclude that improved diseaserelated knowledge may need to be combined with other target variables to induce the desired effect on levels of depression, anxiety and QoL of family members of patients with CHF. Antecedents of depression and anxiety, such as sense of control, may need to be specifically targeted. Our results also suggest that intervention aimed at enhancing social support may be beneficial for family members. Our findings also highlight the importance of assessing the subjective experience of social support of family members to be able to provide appropriate support of family members in their care of close relatives with CHF.
