Study Purpose

To test a telephone-based symptom management (TSM) intervention based on social cognitive theory with patients with lung cancer and their caregivers

Intervention Characteristics/Basic Study Process

The control group received education/support. The goal was to test the effect of TSM on the following patient symptoms: anxiety, pain, breathlessness, fatigue, and depressive symptoms. In caregivers, the focus was on anxiety and depressive symptoms. The intervention group dyads received TSM sessions (each was 45 minutes) for four weeks from a licensed social worker who was trained by a psychologist. The intervention involved giving participants instructions on symptom management, problem solving, cognitive restructuring, emotion focused/self-soothing, communication skills, pleasant activity scheduling, and activity pacing. Participants received identical handouts detailing the points discussed and practice assignment and a CD with instructions for relaxation exercises. The teaching was based on various EB cognitive behavioral and emotion-focused strategies. The sessions focused on both the patient and caregiver.

Sample Characteristics

  • N = 106 patient-caregiver dyads (intervention group = 51 dyads, control group = 55 dyads)   
  • AGE RANGE = TSM group: 20–76 years, control group: 20–80 years
  • MEAN AGe = TSM group: 56.33 years (SD = 14.09), control group: 56.75 years (SD = 13.81)
  • MALES: 27%, FEMALES: 73% of caregivers
  • CURRENT TREATMENT: Other
  • KEY DISEASE CHARACTERISTICS: Caregivers of patients with small and non-small cell lung cancer
  • OTHER KEY SAMPLE CHARACTERISTICS: Dyads were fluent in English, primarily Caucasian, had 13 years of education, and had an average annual household income of $30,000. Sixty-three percent of the caregivers were spouses or partners of the patient. The only difference at baseline between the TSM group and education/support group was caregiver income.

Setting

  • SITE: Multi-site   
  • SETTING TYPE: Outpatient    
  • LOCATION: Indiana

Phase of Care and Clinical Applications

  • PHASE OF CARE: Multiple phases of care
  • APPLICATIONS: Elder care, palliative care 

Study Design

  • Randomized, controlled trial with the intervention group (TSM) compared to education/support group

Measurement Instruments/Methods

Primary outcomes for the caregivers were:

  • Generalized Anxiety Disorder 7-Item Scale (GAD-7) to assess caregiver anxiety symptoms
  • The Patient Health Questionnaire-8 (PHQ-8) to assess for depressive symptoms

Secondary outcomes: 

  • Kilbourn 8-items to assess self-efficacy in managing emotions
  • Social Constraints Scale—5 items to assess perceived social constraints on cancer-related disclosure from the other dyad member

Results

No significant main effects were found for primary outcomes for either patients or caregivers. Small effect size improvement in self-efficacy of caregivers managing their own emotions was observed in the TSM group, while it declined slightly in the education/support group. Also, caregivers in the TSM group reported less perceived social constraints compared to the education/support group. No main effects were noticed in caregivers' self-efficacy in relation to managing patients’ symptoms.

Conclusions

The intervention did not demonstrate a significant effect.

Limitations

  • Small sample (< 100)
  • Risk of bias (no appropriate attentional control condition)
  • Key sample group differences that could influence results
  • Intervention expensive, impractical, or training needs
  • Subject withdrawals ≥ 10%  
  • The intervention included multiple components, so pinpointing cause and effect was difficult.

Nursing Implications

The effect of a nonpharmacological (psychosocial) intervention on the symptoms of patients with lung cancer and their caregivers is inconclusive. Psychosocial interventions improved caregivers’ self-efficacy in managing their emotions and perception of social constraints.
