Study Purpose

To determine whether a therapist-led psychoeducational intervention is effective in reducing anxiety, depression, and radiation therapy-related patient concerns

Intervention Characteristics/Basic Study Process

Patients in the control group received usual care. The intervention group received two face-to-face therapist consultations, one prior to radiation planning and one prior to treatment. Therapists received training in how to prepare patients for radiotherapy planning and treatment, focusing on procedure and sensory and side effect information, as well as training in eliciting and responding to emotional cues. Study measures were obtained at baseline and after each intervention time point. Intervention delivery was recorded, and content analysis was completed to determine intervention fidelity by two reviewers from a randomly selected set of 40 recorded sessions.

Sample Characteristics

  • N = 102
  • MEAN AGE = 54.6 years
  • FEMALES: 100%
  • KEY DISEASE CHARACTERISTICS: All participants were diagnosed with breast cancer and were receiving radiation therapy. About 73% of participants were receiving concomitant chemotherapy.
  • OTHER KEY SAMPLE CHARACTERISTICS: Slightly greater than half of participants were employed part- or full-time, 25% had some college-level education, and one third had less than 10 years of formal education. The majority of participants were married.

Setting

  • SITE: Single-site  
  • SETTING TYPE: Outpatient  
  • LOCATION: Australia

Phase of Care and Clinical Applications

  • PHASE OF CARE: Active antitumor treatment

Study Design

Randomized, controlled trial

Measurement Instruments/Methods

  • Hospital Anxiety and Depression Scale (HADS)
  • Concerns about radiotherapy scale (reliability = .91)
  • Knowledge of radiotherapy scale (reliability = .86)
  • Patient preparedness and understanding index: Single-item Visual Analog Scale (VAS) 

Results

Analysis showed statistically significant intervention effects for anxiety after the first intervention, (p = .0009) but a small size of effect (beta coefficient = –.145). There was no significant effect seen after the second intervention session. There was no effect on depression scores. Knowledge scores increased more on average for the intervention group between baseline and the first intervention session (p < .05) and related concerns dropped more in the intervention group over the same time period (p < .01).

Conclusions

The provision of a psychoeducational intervention was effective in increasing patients’ knowledge, reducing radiation therapy-related concerns, and reducing anxiety in women receiving radiation therapy for breast cancer.

Limitations

  • Risk of bias (no blinding)
  • Risk of bias (no appropriate attentional control condition)
  • Other limitations/explanation: Baseline HADS scores were not provided, so it is not clear whether any patients had clinically-relevant anxiety or depression or if there was a floor effect in measurement.  Usual care was not well-described, so it is not clear how much or what type of information usual care patients received.

Nursing Implications

The provision of this type of education and supportive intervention may reduce anxiety and improve patient knowledge prior to beginning radiation therapy.
