Abstract

Objectives

For patients’ entire families, it can be challenging to live with cancer during the palliative stage. However, a sense of coherence buffers stress and could help health professionals identify families that require support. Therefore, the short version of the Family Sense of Coherence Scale (FSOC-S) was translated, culturally adapted, and validated in a Swedish sample.

Methods

Translation and cross-cultural adaptation of the FSOC-S into Swedish was conducted in accordance with the World Health Organization's Process for Translation and Adaptation of Research Instruments guidelines. Participants were recruited from two oncology clinics and two palliative centers in Sweden.

Results

Content validity was supported by experts (n = 7), persons with cancer (n = 179), and family members (n = 165). Homogeneity among items was satisfactory for persons with cancer and family members (item-total correlations were 0.45‒0.70 and 0.55‒0.72, respectively) as well as internal consistency (ordinal alpha = 0.91 and 0.91, respectively). Factor analyses supported unidimensionality. FSOC-S correlated (rs > 0.3) with hope, anxiety, and symptoms of depression, which supported convergent validity. The test-retest reliability for items ranged between fair and good (kw = 0.37‒0.61).

Significance of Results

The FSOC-S has satisfactory measurement properties to assess family sense of coherence in persons with cancer and their family members. FSOC-S could be used to identify family members who experience low levels of perceived family sense of coherence which provides health care professionals with insight into families’ needs and ability to live with cancer in the palliative stage.
