[Smoking Behaviour after Partial Resection of the Larynx: The Role of Causal Attribution]. / Rauchverhalten von Krebspatienten nach Kehlkopfteilresektion: Welche Bedeutung hat die Kausalattribution?

OBJECTIVE: The aim of our study was to examine how different causal attributions in patients with laryngeal cancer are associated with smoking behaviours (smoking cessation rates and amount of cigarettes per day) after partial resection of the larynx. METHODS: Multicentre prospective cohort study including 4 interviews: between diagnosis and partial resection of larynx (t1), one week (t2), 3 months (t3) and 12 months (t4) after surgery. Presented in this study are t1 and t4. A total of 134 patients (mean age 62 years, 93% male) were interviewed at t1 and t4 between 2007 and 2013. Key items were causal attribution as well as previous and current smoking behaviour. Patients were grouped according to the subjectively stated causal attribution. Results were analysed descriptively and group as well as mean value comparisons were conducted. RESULTS: Smoking was the most commonly stated causal attribution (43.3%). The quantity of cigarettes decreased significantly by about 6 cigarettes from 17 (range 3-40) to 11 (range 2-30) cigarettes per day in this group (p=0.001). 25% of patients did not recognize a reason for their illness. In longitudinal analyses of all groups of different causal attributions, there was a non-significant decrease in the percentage of smokers. CONCLUSION: We show that causal attribution does not affect smoking cessation rate significantly in a positive way. But active smokers after PRL reduce their quantity of cigarettes per day significantly. This impact is more noticeable in patients who were able to define a causal attribution. Psycho-oncological care, information services and smoking cessation programs could contribute to this effect by making the causal attribution a subject of discussion.

Efficacy of the Managing Cancer and Living Meaningfully (CALM) individual psychotherapy for patients with advanced cancer: A single-blind randomized controlled trial.

OBJECTIVE: We aimed to determine whether the Managing Cancer and Living Meaningfully (CALM) therapy is superior to a non-manualized supportive psycho-oncological counselling intervention (SPI). METHODS: Adult patients with advanced cancer and ≥9 points on the PHQ-9 and/or ≥5 points on the DT were randomized to CALM or SPI. We hypothesized that CALM patients would report significantly less depression (primary outcome) on the BDI-II and the PHQ-9 6 months after baseline compared to SPI patients. RESULTS: From 329 eligible patients, 206 participated (61.2% female; age: M = 57.9 [SD = 11.7]; 84.5% UICC IV stage). Of them, 99 were assigned to CALM and 107 to SPI. Intention-to-treat analyses revealed significantly less depressive symptoms at 6 months than at baseline (P < .001 for BDI-II and PHQ-9), but participants in the CALM and SPI group did not differ in depression severity (BDI-II: P = .62, PHQ-9: P = .998). Group differences on secondary outcomes were statistically not significant either. CONCLUSIONS: CALM therapy was associated with reduction in depressive symptoms over time but this improvement was not statistically significant different than that obtained within SPI group.

Spiritual well-being mediates the association between attachment insecurity and psychological distress in advanced cancer patients.

PURPOSE: The diagnosis of a terminal disease bears existential challenges, which activate the attachment system. Attachment insecurity, as well as existential resources, such as spiritual well-being, influences patients' extent of psychological distress. Knowledge about the interrelation of these constructs is limited. Based on current research, we assume spiritual well-being to mediate the association of attachment insecurity and psychological distress. METHODS: We obtained data from the baseline measurement of a randomized controlled trial in advanced cancer patients. Patients were sampled from the University Medical Centers of Hamburg and Leipzig, Germany. Main outcome measures included the Patient Health Questionnaire (PHQ-9), the Death and Dying Distress Scale (DADDS), the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp), and the Experience in Close Relationships Scale (ECR-M16) for assessing attachment insecurity. We tested the mediation hypothesis with two regression analyses using bootstrapping procedure. RESULTS: A total of 190 patients were included. Spiritual well-being mediated the association of attachment insecurity and depression (R2 = 11%), as well as death anxiety (R2 = 15%), in fearful-avoidant attached patients. Neither dismissingly nor preoccupied attached patients differ in terms of spiritual well-being and psychological distress in comparison with secure attached patients. CONCLUSION: Spiritual well-being plays a relevant role in advanced cancer patient's mental health through mediating the association of attachment and psychological distress. Developing a better understanding of the interdependency of the constructs of spiritual well-being and attachment can help to develop individually tailored advanced cancer care programs and psychotherapeutic interventions.

[Assessment of Couples' Communication in Patients with Advanced Cancer: Validation of a German Version of the Couple Communication Scale (CCS)]. / Die Erfassung der Paarkommunikation bei Patienten mit einer fortgeschrittenen Krebserkrankung: Validierung einer deutschen Version der Couple Communication Scale (CCS).

BACKGROUND: There are only a few valid instruments measuring couples' communication in patients with cancer for German speaking countries. The Couple Communication Scale (CCS) represents an established instrument to assess couples' communication. However, there is no evidence regarding the psychometric properties of the German version of the CCS until now and the assumed one factor structure of the CCS was not verified for patients with advanced cancer yet. METHOD: The CCS was validated as a part of the study "Managing cancer and living meaningfully" (CALM) on N=136 patients with advanced cancer (≥18 years, UICC-state III/IV). The psychometric properties of the scale were calculated (factor reliability, item reliability, average variance extracted [DEV]) and a confirmatory factor analysis was conducted (Maximum Likelihood Estimation). The concurrent validity was tested against symptoms of anxiety (GAD-7), depression (BDI-II) and attachment insecurity (ECR-M16). RESULTS: In the confirmatory factor analysis, the one factor structure showed a low, but acceptable model fit and explained on average 49% of every item's variance (DEV). The CCS has an excellent internal consistency (Cronbachs α=0,91) and was negatively associated with attachment insecurity (ECR-M16: anxiety: r=- 0,55, p<0,01; avoidance: r=- 0,42, p<0,01) as well as with anxiety (GAD-7: r=- 0,20, p<0,05) and depression (BDI-II: r=- 0,27, p<0,01). CONCLUSION: The CCS is a reliable and valid instrument measuring couples' communication in patients with advanced cancer.

Perceived doctor-patient relationship and its association with demoralization in patients with advanced cancer.

BACKGROUND: Advanced diseases pose a great burden on patients and go hand in hand with existential concerns. Demoralization is considered as a syndrome of existential distress with a perceived inability to cope with loss of meaning in life and feelings of helplessness and hopelessness. Professional health care providers play an important role in providing support for patients and unfavorable conversational styles in their relationship can increase patient's distress. In this study, we examine the association between the patient's perceived relationship to health care providers and demoralization. METHODS: We used baseline data of a randomized control trial intervention study for advanced cancer patients (UICC-Stage ≥ III; PHQ ≥ 9 and/or Distress-Thermometer ≥5). We used a subscale of the QUAL-EC-P for assessing doctor-patient relationship, Beck Depression Inventory-II for depressive symptoms, a modified version of the MSAS as physiological symptom checklist, and the Demoralization Scale to assess demoralization. A hierarchical regression analysis was calculated. RESULTS: In our sample of 187 patients with stage III or IV cancer (62% women), demoralization was present in 53.4% (16% moderate demoralization; 37.4% high demoralization) of the patients. Relationship to health care provider was an independent predictor (ß = -.33, t(186) = -6.70, P < .001) of demoralization. CONCLUSIONS: Our findings underline the importance of the physician-patient relationship in the context of coping with existential challenges in advanced cancer patients. Trainings on how to communicate and build a sustainable relationship with patients and their specific needs may increase the buffering effect of social support by the physicians on patient's existential distress.

Insecure attachment predicts depression and death anxiety in advanced cancer patients.

ABSTRACTObjective:The prevalence of depression as well as adjustment and anxiety disorders is high in advanced cancer patients, and research exploring intraindividual factors leading to high psychological distress is underrepresented. Cancer patients' feelings about security and trust in their healthcare providers have a significant influence on how they deal with their disease. The perception of social support is affected by patients' attachment styles and influences their reactions to feelings of dependency and loss of control. We therefore aimed to explore attachment and its association with psychological distress in patients with advanced cancer. METHOD: We obtained data from the baseline measurements of a randomized controlled trial in advanced cancer patients. Patients were sampled from the university medical centers of Hamburg and Leipzig, Germany. The main outcome measures included the Patient Health Questionnaire, the Death and Dying Distress Scale, the Memorial Symptom Assessment Scale, and the Experience in Close Relationships Scale for assessing attachment insecurity. RESULTS: A total of 162 patients were included. We found that 64% of patients were insecurely attached (fearful-avoidant 31%, dismissing 17%, and preoccupied 16%). A dismissing attachment style was associated with more physical symptoms but did not predict psychological distress. A fearful-avoidant attachment style significantly predicted higher death anxiety and depression, whereas preoccupied attachment predicted higher death anxiety only. Overall, insecure attachment contributed to the prediction of depression (10%) and death anxiety (14%). SIGNIFICANCE OF RESULTS: The concept of attachment plays a relevant role in advanced cancer patients' mental health. Healthcare providers can benefit from knowledge of advanced cancer patients' attachment styles and how they relate to specific mental distress. Developing a better understanding of patients' reactions to feelings of dependency and distressing emotions can help us to develop individually tailored advanced cancer care programs and psychotherapeutic interventions.

Efficacy of a brief manualized intervention Managing Cancer and Living Meaningfully (CALM) adapted to German cancer care settings: study protocol for a randomized controlled trial.

BACKGROUND: Although psycho-oncological interventions have been shown to significantly reduce symptoms of anxiety and depression and enhance quality of life, a substantial number of patients with advanced cancer do not receive psycho-oncological interventions tailored to their individual situation. Given the lack of reliable data on the efficacy of psycho-oncological interventions in palliative care settings, we aim to examine the efficacy of a brief, manualized individual psychotherapy for patients with advanced cancer: Managing Cancer and Living Meaningfully (CALM). CALM aims to reduce depression and death anxiety, to strengthen communication with health care providers, and to enhance hope and meaning in life. We adapted the intervention for German cancer care settings. METHODS/DESIGN: We use a single-blinded randomized-controlled trial design with two treatment conditions: intervention group (IG, CALM) and control group (CG). Patients in the CG receive a usual non-manualized supportive psycho-oncological intervention (SPI). Patients are randomized between the IG and CG and assessed at baseline (t0), after three (t1) and after 6 months (t2). We include patients with a malignant solid tumor who have tumor stages of III or IV (UICC classification). Patients who are included in the study are at least 18 years old, speak German fluently, score greater than or equal to nine on the PHQ-9 or/and greater than or equal to five on the Distress Thermometer. It is further necessary that there is no evidence of severe cognitive impairments. We measure depression, anxiety, distress, quality of life, demoralization, symptom distress, fatigue as well as spiritual well-being, posttraumatic growth and close relationship experiences using validated questionnaires. We hypothesize that patients in the IG will show a significantly lower level of depression 6 months after baseline compared to patients in the CG. We further hypothesize a significant reduction in anxiety and fatigue as well as significant improvements in psychological and spiritual well-being, meaning and post-traumatic growth in the IG compared to CG 6 months after baseline. DISCUSSION: Our study will contribute important statistical evidence on whether CALM can reduce depression and existential distress in a German sample of advanced and highly distressed cancer patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT02051660.

Death-Related Anxiety in Patients With Advanced Cancer: Validation of the German Version of the Death and Dying Distress Scale.

CONTEXT: Distress and anxiety about issues related to death and dying is commonly experienced in patients with advanced disease and a limited life expectancy. OBJECTIVES: To evaluate the psychometric properties of the German version of the Death and Dying Distress Scale (DADDS-G) in advanced cancer patients. METHODS: We recruited advanced patients with mixed tumor entities (Union for International Cancer Control [UICC] Stage III/IV) treated in two German University Medical Centers during their outpatient treatment. After testing a preliminary version of the state-of-the-art translated original Death and Dying Distress Scale, we analyzed the psychometric properties of the shortened nine-item adapted DADDS-G using validated instruments measuring distress, anxiety, depression, fear of progression, and quality of life. RESULTS: We obtained complete questionnaires from 77 of 93 patients with advanced cancer (response rate: 83%). Participants were mostly married or cohabiting (75%), well-educated, and both sexes were almost equally represented (52% men; mean age 58 years, SD = 12). The total mean DADDS-G score was 13.3 (SD = 8.5). Patients reported to be most distressed by the feeling of being a burden to others. The exploratory factor analysis led to one factor that accounted for more than 59% of the variance. The DADDS-G's internal consistency was excellent with Cronbach alpha = 0.91. The confirmatory factor analysis demonstrated a very good model fit. Death-related anxiety was significantly associated with distress, depression, anxiety, fear of progression, and lower quality of life (P < 0.001). CONCLUSION: Results provide further evidence that the DADDS-G is a valid and reliable instrument of high clinical relevance for use in patients with advanced cancer.
