Cancer-coping profile predicts long-term psychological functions and quality of life in cancer survivors.

PURPOSE: Cancer survivors experience significant psychosocial distress even after completion of cancer treatment. The association between cancer coping and cancer recovery is not well established. The present study investigated the cancer-coping profile and cancer outcomes in breast cancer survivors. METHODS: A three-wave longitudinal study was conducted. In 2009 (wave 1), 248 breast cancer survivors completed a package of psychological inventories to evaluate cancer copying style, psychological distress, anxiety and depression, and quality of life. They received follow-up survey in 2012 (wave 2) and 2016 (wave 3). A latent profile analysis (LPA) was conducted among participants in wave 1 to identify cancer-coping class. Identified cancer-coping class was used to predict psychological and survival outcomes in waves 2 and 3. RESULTS: Two cancer-coping classes were identified through LPA, namely adaptive cancer coping (class I; 52%) and maladaptive cancer coping (class II; 47.8%). Demographic and clinical factors did not differ significantly between the two classes. Subsequent analyses demonstrated that the cancer-coping style in wave 1 predicted the psychological symptoms and quality of life outcomes at the two follow-ups (waves 2 and 3). Survivors in the adaptive group (class I) exhibited lower cancer distress, anxiety and depression scores, and higher quality of life scores than those in the maladaptive group did. Cancer coping were not found to be significantly associated with cancer survival or recurrence. CONCLUSIONS: The identified cancer-coping styles were predictive of the survivors' psychological symptoms, psychological well-being, and health-related quality of life but not cancer survival or recurrence.

Revisiting the Continuing Bonds Theory: The Cultural Uniqueness of the Bei Dao Phenomenon in Taiwanese Widows/Widowers.

In the present study, we used the phenomenological approach to rediscover the ontological meaning of relationships with the deceased in Taiwanese widows/widowers. We first revised the original Western definitions of grief, bereavement, and mourning to fit Taiwanese culture. We used the word bei dao to indicate the mixed nature of grief and mourning in the Taiwanese bereavement process. Then we reanalyzed data from a previous study, which was conducted in 2006. In the previous qualitative research, each subject was interviewed 3 to 4 times in the mourning state over an 18-month interval that began at the point of the spouse's death. Results showed that two main themes emerged in the present analysis: (a) a blurred boundary of life and death and (b) a transformation of ethical bonds. The present study reveals the culturally unique aspects of the Taiwanese bei dao process. Limitations of the present study and future directions are discussed and reflected.

Prevalence, risk factors, and the desire for help of distressed newly diagnosed cancer patients: A large-sample study.

OBJECTIVE: Beginning in 2007, all newly diagnosed cancer patients at the Koo Foundation Sun Yat-Sen Cancer Center (KF-SYSCC) were screened for psychosocial distress. Our social workers, as part of the psychosocial care team (PCT), have engaged in proactive outreach with patients identified as distressed. The goal of the present study was to assess the prevalence of psychosocial distress and the extent of contact between the PCT and distressed patients. METHOD: Newly diagnosed patients who were treated at KF-SYSCC between 2007 and 2010 for cancer were eligible if there were at least 100 patients with the same type of cancer. Before treatment began, they were screened with the Pain Scale and the Distress Thermometer (DT) and had the option to specify a desire for help. The rates of distress were analyzed by cancer type and by probable related factors. Information regarding contact with the PCT was retrieved from computerized databases. RESULTS: Overall, some 5,335 cancer patients representing 12 major cancer types were included in our study. Of these, 1,771 (33.20%) were significantly distressed. By multivariate logistic regression, younger age, female gender, higher pain score, and disease stage, but not cancer type, were found to be associated with higher rates of distress. Among these distressed patients, 628 (36%) had some contact with the PCT. SIGNIFICANCE OF RESULTS: This Taiwanese study with a large sample size revealed a prevalence rate of psychosocial distress similar to rates found in Western countries. Contact with the PCT was established in only 36% of significantly distressed patients, despite a proactive outreach program. It is very important to have screening results made available in a timely fashion to the psycho-oncology team so that appropriate care can be offered promptly.

Psychometric analysis of the Chinese version of the Posttraumatic Growth Inventory with cancer patients in Hong Kong and Taiwan.

OBJECTIVE: Cancer patients in Hong Kong and Taiwan share traditional Chinese as a written form of language, but each region has its own sociocultural background. This study examined if the four-factor model (self, spiritual, life orientation, and interpersonal) of the Chinese version of the Posttraumatic Growth Inventory (PTGI-C), developed for Hong Kong cancer survivors, could be applied to cancer survivors in Taiwan. METHODS: Multisample confirmatory factor analyses (MS-CFA) were used to examine the factorial invariance of the PTGI-C among cancer survivors in Taiwan (n = 217) and Hong Kong (n = 223). RESULTS: The goodness-of-fit of the four-factor model was satisfactory, χ²(180) = 372.36 (χ²/df = 2.07), goodness-of-fit index (GFI) = 0.90, adjusted GFI (AGFI) = 0.87, comparative fit index (CFI) = 0.92, Tucker-Lewis index (TLI) = 0.91, root mean square error of approximation (RMSEA) = 0.05, Akaike information criterion (AIC) = 492.36. This result suggests that the factor structure of the PTGI-C developed in Hong Kong could be applied to cancer survivors in Taiwan. The internal reliabilities of the 15-item whole scale, as well as all the subscales, were good and similar to those reported previously. Interregion comparison revealed that the Taiwan sample had higher mean 'spiritual' and 'interpersonal' posttraumatic growth subscale scores than the Hong Kong sample. CONCLUSIONS: The four-factor model of the PTGI-C is invariant among cancer survivors using traditional Chinese as a written form of the language. The differences in the degree of some posttraumatic growth dimensions may be because of differences in cultural factors and in psychosocial support for cancer patients between the two regions.

Constructive, illusory, and distressed posttraumatic growth among survivors of breast cancer: A 7-year growth trajectory study.

A total of 84 breast cancer survivors completed a package of psychological inventories in 2009 (Time 1), 2012 (Time 2), and 2016 (Time 3). Latent class growth analysis revealed three posttraumatic growth trajectory patterns: distressed posttraumatic growth (n = 5, 6.7%), illusory posttraumatic growth (n = 42, 56.0%), and constructive posttraumatic growth (n = 28, 37.3%). Women with more frequent use of helplessness-hopelessness coping and lower depression levels at Time 1 were more likely to display an illusory than a constructive posttraumatic growth trajectory pattern. Illusory posttraumatic growth might represent a form of coping rather than authentic positive changes. Researchers and clinicians should understand different patterns of posttraumatic growth.

Effects of TiO2 and TiC Nanofillers on the Performance of Dye Sensitized Solar Cells Based on the Polymer Gel Electrolyte of a Cobalt Redox System.

Polymer gel electrolytes (PGEs) of cobalt redox system are prepared for dye sensitized solar cell (DSSC) applications. Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) is used as a gelator of an acetonitrile (ACN) liquid electrolyte containing tris(2,2'-bipyridine)cobalt(II/III) redox couple. Titanium dioxide (TiO2) and titanium carbide (TiC) nanoparticles are utilized as nanofillers (NFs) of this PGE, and the effects of the two NFs on the conductivity of the PGEs, charge-transfer resistances at the electrode/PGE interface, and the performance of the gel-state DSSCs are studied and compared. The results show that the presence of TiC NFs significantly increases the conductivity of the PGE and decreases the charge-transfer resistance at the Pt counter-electrode (CE)/PGE interface. Therefore, the gel-state DSSC utilizing TiC NFs can achieve a conversion efficiency (6.29%) comparable to its liquid counterpart (6.30%), and, furthermore, the cell efficiency can retain 94% of its initial value after a 1000 h stability test at 50 °C. On the contrary, introduction of TiO2 NFs in the PGE causes a decrease of cell performances. It shows that the presence of TiO2 NFs increases the charge-transfer resistance at the Pt CE/PGE interface, induces the charge recombination at the photoanode/PGE interface, and, furthermore, causes a dye desorption in a long-term-stability test. These results are different from those reported for the iodide redox system and are ascribed to a specific attractive interaction between TiO2 and cobalt redox ions.
