ABSTRACT
INTRODUCTION: Cancer survivors have reduced health-related quality of life (HRQOL) due to impaired daily functioning. In addition, daily stress leads to worsening oxidative stress. The purpose of this study is to investigate the efficacy of laughter therapy on HRQOL and oxidative stress in cancer survivors. METHODS: This before-and-after study asked cancer survivors to watch a 15-minute or longer comedy video over a four-week period to assess the Functional Assessment of Cancer Therapy-General (FACT-G), EuroQOL 5 dimension 3-level (EQ-5D-3L), Hospital Anxiety and Depression Scale (HADS), biological Antioxidant Potential (BAP), Reactive Oxygen Metabolites-derived compounds (d-ROMs), Oxidative Stress Index (OSI), and the antioxidant/oxidative stress ratio. RESULTS: The nonparametric Friedman test showed significant increases from baseline in FACT-G and EQ-VAS scores and significant decreases in HADS-Anxiety and HADS-Depression scores. Post hoc analyses showed that these items commonly differed significantly at baseline versus three and four weeks after Bonferroni correction. T-test results in the biological analysis revealed small and moderate effects with significant differences in BAP (p < 0.01, d = 0.49), OSI (p = 0.03, d = 0.33), and BAP/d-ROMs (p < 0.01, d = 0.51). CONCLUSION: These results suggest that daily comedy viewing may be an effective intervention to improve quality of life and antioxidant capacity in cancer survivors. Considering its safety, convenience, and low cost, it should be considered a high-value intervention for cancer survivors.
ABSTRACT
OBJECTIVE: The current report provides the result of a Phase II clinical trial regarding the effectiveness and feasibility of problem-solving therapy for psychological distress experienced by Japanese early-stage breast cancer patients. METHODS: Participants were 36 post-surgery Japanese breast cancer patients in a university hospital located in Osaka Prefecture, Japan. After screening for psychological distress using the Distress and Impact Thermometer and the Hospital Anxiety and Depression Scale, highly distressed patients were exposed to 5 weekly sessions of the problem-solving therapy program. RESULTS: Nineteen patients completed the intervention and follow-up. There was a significant difference between the pre-intervention and the 3-month follow-up in the total Hospital Anxiety and Depression Scale score (P = 0.02), and the mean change score from the pre-intervention to the follow-up was 6.05 (SD = 1.94). The intervention had a large effect size (d = 0.82). There were also significant changes in worry, self-efficacy and quality of life measures. CONCLUSIONS: The findings of our study suggest that the problem-solving therapy program has potential to be effective for alleviating psychological distress experienced by Japanese early-stage breast cancer patients. The true effectiveness of the program should be confirmed by a future randomized control trial.

Problem-solving therapy (PST) is a brief, structured psychological treatment. Preliminary clinical findings regarding the effectiveness of PST for treating psychological distress experienced by Japanese cancer patients are presented. Our actual clinical experience in administering PST to four consecutive distressed cancer patients was reviewed. All of the patients were breast cancer survivors who were referred to us after undergoing surgery. Three cases received six PST sessions each and one case received three PST sessions. The depression and anxiety scores decreased after PST. Our preliminary experience suggests that PST is an effective treatment for alleviating psychological distress in Japanese cancer patients and that this treatment should be further examined in a clinical trial.

OBJECTIVES: A psychometric scale for assessing cancer-related worry among cancer patients, called the Brief Cancer-Related Worry Inventory (BCWI), was developed. METHODS: A cross-sectional questionnaire survey for item development was conducted of 112 Japanese patients diagnosed with breast cancer, and test-retest validation analysis was conducted using the data from another prospective study of 20 lung cancer patients. The questionnaire contained 15 newly developed items for cancer-related worry, the Hospital Anxiety and Depression Scale, The Impact of Event Scale Revised, and the Medical Outcomes Study Short Form-8. RESULTS: Exploratory factor analysis of the 15 items yielded a 3-factor structure including (1) future prospects, (2) physical and symptomatic problems and (3) social and interpersonal problems. A second-order confirmatory factor analysis identified a second-order factor called cancer-related worry and confirmed the factor structure with an acceptable fit (chi-square (df=87)=160.16, P=0.001; GFI=0.83; CFI=0.92; RMSEA=0.09). The internal consistency and test-retest reliability were confirmed with the lung cancer sample. Multidimensional scaling found that cancer-related worry is separate from anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms. CONCLUSION: Our study succeeded in developing and confirming the validity and reliability of a BCWI. The study also confirmed the discriminable aspects of cancer-related worry from anxiety, depression, and PTSD symptoms.
