Examining the Role of Resilience, Posttraumatic Growth, and Quality of Life in Women with Breast Cancer: A Serial Multiple Mediator Model Approach.

OBJECTIVES: It is unclear how resilience and posttraumatic growth help women with breast cancer face cancer-related symptom distress. This study included both resilience and posttraumatic growth as mediators in a serial multiple mediator model to examine changes in the relationship between symptom distress and quality of life among women with breast cancer. DATA SOURCES: We conducted the descriptive, cross-sectional study in Taiwan. Data were collected using a survey that assessed symptom distress, resilience, posttraumatic growth, and quality of life. A serial multiple mediator model examined one direct and three specific indirect effects of symptom distress on quality of life through resilience and posttraumatic growth. All 91 participants reported the presence of symptom distress and moderate levels of resilience. Quality of life was significantly associated with symptom distress (b = -1.04), resilience (b = 0.18), and posttraumatic growth (b = 0.09). The indirect effect of symptom distress on quality of life through resilience alone was statistically significant (b = -0.23, 95% CI -0.44 to -0.07) and statistically greater than the specific indirect effect through resilience and posttraumatic growth combined (b = -0.21, 95% CI -0.40 to -0.05). CONCLUSION: Resilience plays a unique role in reducing the impact of symptom distress on the quality of life among women with breast cancer. IMPLICATIONS FOR NURSING PRACTICE: Given the importance of resilience to quality of life, oncology nurses can assess the resilience of women with breast cancer and help identify available internal, external, and existential resources to strengthen their resilience.

Examining the Psychometric Properties of the Taiwanese Version of the Hospice Quality of Life Index.

Quality of life is an important outcome for people with cancer throughout their cancer trajectory. Having a valid and reliable instrument to measure the quality of life is critical. This cross-sectional study examined the psychometric properties of the Taiwanese version of the Hospice Quality of Life Index among patients with advanced cancer in Taiwan. There were 3 phases: (1) translation of the Hospice Quality of Life Index from English to Mandarin, (2) pilot testing among 30 targeted participants, and (3) field testing to examine validity and reliability. The results of confirmatory factor analysis indicated that the original factor structure of the Hospice Quality of Life Index did not fit the data. After 5 items were deleted from the original questionnaire, principal factor extraction with oblique rotation for exploratory factor analysis yielded 3 subscales: Social/Spiritual Well-Being, Psychological Well-Being, and Functional/Physiological Well-Being. For convergent validity, the small to moderate strength of associations showed shared variance with the Memorial Symptom Assessment Scale. The internal consistency was supported by Cronbach α ranging from 0.77 to 0.86. This study shows early evidence that the quality of life of people with advanced cancer can be appropriately assessed by the Taiwanese Hospice Quality of Life Index.

Measurement Invariance of the Hospice Quality of Life Index-14 in Lung Cancer and Nonlung Cancer Patients Admitted to Hospice.

Background and Purpose: Establishing measurement invariance (MI) is important in the questionnaire validation process. This study examined the MI of the Hospice Quality of Life Index-14 (HQLI-14) when comparing hospice patients with lung cancer and those with non-lung cancers. Methods: The HQLI-14 contains 14 items to measure multidimensional concepts of quality of life. A series of confirmatory factor analyses were performed to test configural, metric, and scalar invariance. Results: The MI of the HQLI-14 was supported by increasing equality constraints on item parameters between groups. Although the configural and metric invariances were both supported, one item regarding breathlessness was noninvariant between the groups with lung and nonlung cancers. Conclusions: The HQLI-14 shows early evidence of meeting the requirements for configural, metric, and partial scalar invariance. It may be used to make meaningful comparisons between patients with lung cancer and nonlung cancers.

Symptom Distress and Quality of Life in Women With Newly Diagnosed Ovarian Cancer Undergoing Chemotherapy: A Longitudinal Approach.

BACKGROUND: Women with newly diagnosed ovarian cancer who receive chemotherapy experience distressing symptoms and reduced quality of life (QOL). Previous study results identifying changes in symptom distress and QOL over time are limited. OBJECTIVES: This study examined the trajectory of symptom distress and QOL among women with newly diagnosed ovarian cancer from before their first chemotherapy appointment to two weeks after completing six cycles of chemotherapy. METHODS: A longitudinal design was used to examine symptom distress and QOL in 36 participants across eight time points. Generalized estimating equation analyses identified how participants' symptom distress and QOL changed over time. FINDINGS: Psychological symptom distress was highest at baseline and then decreased. Physical symptom distress increased at the second chemotherapy cycle. Similar results were found for QOL, with the lowest QOL reported after the fifth cycle.
