The relationship between negative emotions and avoidance is widely theorized as a bidirectional cycle implicated in a range of psychopathology. Historically, research on this cycle has examined one type of negative emotion: anxiety. Yet, a broader range of internal experiences may be implicated in the maintenance of unhealthy avoidance cycles in psychopathology. This study examines prospective relationships among anxiety, guilt, physical discomfort, and experiential avoidance during mealtimes for individuals with eating disorders (EDs). Participants (N = 108) completed ecological momentary assessments four times a day for 25 days. We computed multilevel models to examine between- and within-person effects of negative emotions and physical discomfort on experiential avoidance. When including guilt and anxiety in one model, guilt, but not anxiety, explained the significant variance in experiential avoidance at the next meal. Mealtime physical discomfort and experiential avoidance evidenced reciprocal prospective relationships. Future research should test whether interventions targeting experiential avoidance and physical discomfort at mealtimes disrupt guilt.
Meaning-centered psychotherapy (MCP) has been found to be effective in improving meaning in life and increasing fulfillment in participants with cancer. However, to date, no previous studies have compared MCP with evidence-based treatments such as cognitive behavioral therapy (CBT). The aim of this study was to analyze the differential efficacy of MCP, compared to CBT, in participants with cancer. The study is a randomized controlled trial with 76 participants, n = 41 (MCP) and n = 35 (CBT). At posttreatment, the MCP intervention for cancer survivors was more effective than CBT in increasing the presence of meaning in life, purpose and meaning in life, and life goals. Moreover, our results showed that, at posttreatment and the 6-month follow-up, MCP and CBT were similarly effective in improving depression and developing posttraumatic growth. This study suggests that MCP could be more effective than CBT in improving meaning in life, purpose, and life goals, and equally effective as CBT in improving depression and posttraumatic growth, in cancer survivors.
