To explore the effectiveness of psycho-oncologic interventions for patients and partners on anxiety, depression, psychopathology, and distress
Patients and partners who had been referred for psycho-oncologic service were recruited. Common interventions were psychoeducation, cognitive restructuring, behavior control techniques, guided imagery, relaxation, couples communication training, and other types of counseling in an individualized, nonstandard fashion. Patients and partners were grouped according to propensity scores calculated from variables shown to be significant in regression analysis for outcomes of interest, including gender, age, cancer site, stage of disease, baseline anxiety, and depression. Propensity matched control patients, and partners who did not receive the intervention were identified and used as control comparisons. Analysis was done in groupings according to the level of distress with propensity scores as low-, moderate-, or high-distress.
Time effects within patient groups showed significant decreases over time in depression and distress (p ≤ .05), but not for anxiety and psychopathology. No group effects were seen on outcomes over time. Among partners, no changes were seen over time and no significant effects of the intervention were seen on outcomes. The same pattern was seen in completer and intent to treat analysis. Pre- and post-intervention data showed that patients had significant declines in anxiety (effect size Cohen’s d = 0.32, p = .01), distress (d = .46, p = .001), and depression (d = 0.52, p = .001) at 12 months, and partners had significant declines in anxiety (d = 0.45, p = .01) and distress (d = .42, p = .02) within the highly distressed group. No significant differences were seen in the less distressed group over time.
Findings suggest that psychotherapeutic interventions can reduce anxiety, distress, and depression among patients and partners who are highly distressed. Little benefit may exist for individuals who are less anxious or distressed at baseline.
Psychotherapeutic interventions may be beneficial for patients and caregivers who are highly distressed. Nurses need to be aware of the overall level of patient and caregiver distress and identify those who are likely to benefit from referral for therapy.
