Abstract

Objective: This study examined relations between acceptance and commitment therapy (ACT) constructs and symptom-based subgroups of advanced cancer patients.

Methods: Patients with advanced breast, gastrointestinal, lung, and prostate cancer (N = 201) completed questionnaires assessing five common symptoms and ACT variables (i.e., psychological inflexibility, cognitive fusion, values obstruction and progress, peaceful acceptance, mindfulness, and activity engagement) on one occasion.

Results: Latent profile analysis showed three patient classes: (1) normal levels of all symptoms (32%); (2) normal levels of all symptoms except for mild sleep problems and moderate fatigue (19%); and (3) normal pain, mild levels of sleep problems, anxiety, and depressive symptoms, and moderate fatigue (48%). Controlling for demographic covariates, lower psychological inflexibility, cognitive fusion, and values obstruction were associated with a higher likelihood of being in classes 1 or 2 than class 3. In addition, greater values progress, peaceful acceptance, mindfulness, and activity engagement were associated with a higher likelihood of being in class 1 than class 3. Of these four factors, only greater mindfulness and activity engagement were associated with a higher likelihood of being in class 2 than class 3.

Conclusions: Advanced cancer patients show heterogeneous symptom profiles, and even mild to moderate symptom levels are related to greater withdrawal from personally meaningful activities and less acceptance of cancer and internal experiences (e.g., symptoms, thoughts, feelings). Findings are consistent with the ACT model and support further testing of ACT to address symptom interference with functioning in advanced cancer patients.
