Abstract

OBJECTIVE:

To explore the structure of symptom distress in women with advanced lung cancer.

DESIGN:

Descriptive.

SETTING:

Oncology clinics and private offices.

SUBJECTS:

Sixty women with advanced lung cancer (71% non-small-cell); the majority received palliative treatment (88%).

OUTCOME MEASURES:

Symptom Distress Scale and Karnofsky Performance Status Scale.

METHOD:

Factor analytic techniques (principal components, varimax rotation) to investigate combinations of all symptoms in the Symptom Distress Scale and combinations of serious symptoms.

RESULTS:

Fatigue, disruptions in outlook, frequent pain, and difficulties in sleeping were rated the most distressing and were the most prevalent serious disruptions. A four-factor solution for the symptom distress ratings explained 63.3% of the variance and revealed groups of items representing emotional and physical suffering, gastrointestinal distress, respiratory distress, and malaise. Symptoms with a rating of serious distress were represented by five factors with emotional and physical suffering as separate factors. Symptoms were significantly related to Karnofsky Performance Status.

CONCLUSIONS:

Multiple symptoms formed distinct congregations of distress. Symptom control requires consideration as a multivariate approach.
