RESUMEN
PURPOSE/OBJECTIVES: Adolescent and young adults who have survived cancer are at an increased risk of psychological distress. This study investigated whether metacognitive beliefs are associated with emotional distress and trauma symptoms in adolescent and young adult (AYA) survivors of cancer independent of known covariates, including current physical health difficulties. DESIGN: Cross-sectional survey using multiple self-report measures. SAMPLE AND METHODS: Eighty-seven AYA survivors of cancer were recruited from follow-up appointments at an oncology unit and completed self-report questionnaires measuring emotional distress, posttraumatic stress symptoms, metacognitive beliefs, demographic information, and current physical health difficulties. Data were analysed using correlational and hierarchical multiple regression analyses. FINDINGS: Metacognitive beliefs explained an additional 50% and 41% of the variance in emotional distress and posttraumatic stress symptoms, respectively, after controlling for known covariate effects, including current physical health difficulties. Conclusions/Implications for Psychosocial Providers or Policy: The metacognitive model of psychopathology is potentially applicable to AYA survivors of cancer who present with elevated general distress and/or posttraumatic stress symptoms. Prospective studies are required to determine whether metacognitive beliefs and processes have a causal role in distress in AYA survivors of cancer.

OBJECTIVE: Systematic reviews highlight a broad range of cancer-related post-traumatic stress disorder (CR-PTSD) prevalence estimates in cancer survivors. This meta-analysis was conducted to provide a prevalence estimate of significant CR-PTSD symptoms and full diagnoses to facilitate the psychological aftercare of cancer survivors. METHODS: A systematic literature search was conducted for studies using samples of cancer survivors by using validated clinical interviews and questionnaires to assess the prevalence of CR-PTSD (k = 25, n = 4189). Prevalence estimates were calculated for each assessment method using random-effects meta-analysis. Mixed-effects meta-regression and categorical analyses were used to investigate study-level moderator effects. RESULTS: Studies using the PTSD Checklist-Civilian Version yielded lower event rates using cut-off [7.3%, 95% confidence intervals (CI) = 4.5-11.7, k = 10] than symptom cluster (11.2%, 95% CI = 8.7-14.4, k = 9). Studies using the Structured Clinical Interview for Diagnostic and Statistical Manual, Fourth Edition (SCID), yielded low rates for lifetime (15.3%, 95% CI = 9.1-25, k = 5) and current CR-PTSD (5.1%, 95% CI = 2.8-8.9, k = 9). Between-study heterogeneity was substantial (I(2) = 54-87%). Studies with advanced-stage samples yielded significantly higher rates with PTSD Checklist-Civilian Version cluster scoring (p = 0.05), and when assessing current CR-PTSD on the SCID (p = 0.05). The effect of mean age on current PTSD prevalence met significance on the SCID (p = 0.05). SCID lifetime prevalence rates decreased with time post-treatment (R(2) = 0.56, p < 0.05). DISCUSSION: The cancer experience is sufficiently traumatic to induce PTSD in a minority of cancer survivors. Post-hoc analyses suggest that those who are younger, are diagnosed with more advanced disease and recently completed treatment may be at greater risk of PTSD. More research is needed to investigate vulnerability factors for PTSD in cancer survivors. © 2014 The Authors. Psycho-Oncology published by John Wiley & Sons Ltd.

BACKGROUND: Cognitive Behavioural Therapy (CBT) is not primarily conceptualized as operating via affective processes. However, there is growing recognition that emotional processing plays an important role during the course of therapy. AIMS: The Emotional Processing Scale was developed as a clinical and research tool to measure emotional processing deficits and the process of emotional change during therapy. METHOD: Fifty-five patients receiving CBT were given measures of emotional functioning (Toronto Alexithymia Scale [TAS-20]; Emotional Processing Scale [EPS-38]) and psychological symptoms (Brief Symptom Inventory [BSI]) pre- and post-therapy. In addition, the EPS-38 was administered to a sample of 173 healthy individuals. RESULTS: Initially, the patient group exhibited elevated emotional processing scores compared to the healthy group, but after therapy, these scores decreased and approached those of the healthy group. CONCLUSIONS: This suggests that therapy ostensibly designed to reduce psychiatric symptoms via cognitive processes may also facilitate emotional processing. The Emotional Processing Scale demonstrated sensitivity to changes in alexithymia and psychiatric symptom severity, and may provide a valid and reliable means of assessing change during therapy.

Background: Adult cancer survivors often experience substantial psychological morbidity following the completion of acute cancer treatment. Unfortunately, current psychological interventions are of limited efficacy. This study explored if metacognitive therapy (MCT); a brief transdiagnostic psychological intervention was potentially efficacious and could be delivered effectively to adult cancer survivors with psychological morbidity. Methods: An open trial with 3- and 6-month follow-up evaluated the treatment effects of MCT in 27 consecutively referred individuals to a clinical psychology health service specializing in psycho-oncology. Each participant received a maximum of six 1-hour sessions of MCT. Levels of anxiety, depression, fear of cancer recurrence, post-traumatic stress symptoms, health related quality of life, and metacognitive beliefs and processes were assessed using self-report questionnaires. Results: MCT was associated with statistically significant reductions across all outcome measures which were maintained through to 6-month follow-up. In the ITT sample on the primary treatment outcome measure, the Hospital Anxiety and Depression Scale-Total, 59% of participants met recovery criteria at post-treatment and 52% at 6-month follow-up, respectively. No participants significantly deteriorated. In the completer sample (N = 20), 80% recovered at post-treatment and 70% at 6-month follow-up. MCT was acceptable to patients with approximately 75% of patients completing all treatment sessions. Conclusion: MCT, a brief transdiagnostic psychological intervention can be delivered effectively to a heterogenous group of cancer survivors with promising treatment effects. Examining the efficacy of brief MCT against the current gold standard psychological intervention would be a valuable advance toward improving the quality of life of cancer survivors.
RESUMEN
BACKGROUND: Preliminary evidence suggests that metacognitive therapy (MCT), a brief, process-focused psychological intervention, alleviates distress in cancer survivors. In a longitudinal qualitative study nested in an open trial of MCT for cancer survivors, we explored how patients understood, experienced and applied MCT. METHODS: Patients received six MCT sessions. Consenting patients provided semi-structured interviews post-intervention (n = 19), and at 3- and 6-months follow-up (n = 14 and 10 respectively). Interviews were audio-recorded and transcribed. Analysis followed a constant comparison approach. RESULTS: Participants felt "overwhelmed" by worry before starting MCT and doubted that such brief therapy could help. Their accounts focused on feeling "challenged" to think differently by the psychologist. Those completing therapy were enthusiastic about it. They described having learned that thoughts are "only thoughts," that feelings of worry or sadness are a normal part of life, and that they were in control of whether and how they engaged with thoughts. Consequently, most described a sense of freedom to live free from worry. A minority described being unable to apply MCT to certain thoughts. Two patients who withdrew before completing MCT did not describe having learned what MCT was intended to achieve. CONCLUSION: MCT is an acceptable brief intervention for distressed cancer survivors. Feeling challenged to understand the processes maintaining their distress was central to their enthusiasm for it, irrespective of their presenting difficulties. IMPLICATIONS FOR CANCER SURVIVORS: The complexity of emotional distress in cancer survivors can potentially be addressed using a transdiagnostic model which focuses on the psychological processes which maintain distress.
