Based on self-regulation and self-efficacy theories, the Cancer Behavior Inventory (CBI; Heitzmann et al., 2011; Merluzzi & Martinez Sanchez, 1997; Merluzzi, Nairn, Hegde, Martinez Sanchez, & Dunn, ...2001) was developed as a measure of self-efficacy strategies for coping with cancer. In the latest revision, CBI-V3.0, a number of psychometric and empirical advances were made: (a) the reading level was reduced to 6th-grade level; (b) individual interviews and focus groups were used to revise items; (c) a new spiritual coping subscale was added; (d) data were collected from 4 samples (total N = 1,405) to conduct an exploratory factor analysis with targeted rotation, 2 confirmatory factor analyses, and differential item functioning; (e) item trimming was used to reduce the total number to 27; (f) internal consistency and test-retest reliability were computed; and (g) extensive validity testing was conducted. The results, which build upon the strengths of prior versions, confirm a structurally and psychometrically sound and unbiased measure of self-efficacy strategies for coping with cancer with a reduced number of items for ease of administration. The factors include Maintaining Activity and Independence, Seeking and Understanding Medical Information, Emotion Regulation, Coping With Treatment Related Side Effects, Accepting Cancer/Maintaining a Positive Attitude, Seeking Social Support, and Using Spiritual Coping. Internal consistency (α = .946), test-retest reliability (r = .890; 4 months), and validity coefficients with a variety of relevant measures indicated strong psychometric properties. The new 27-item CBI-V3.0 has both research utility and clinical utility as a screening and treatment-planning measure of self-efficacy strategies for coping with cancer.
Public Significance Statement
This study describes a comprehensive revision of the Cancer Behavior Inventory (CBI), a 27-item self-report survey that assesses strategies for coping with cancer. Higher scores on the CBI are associated with better adjustment to cancer, higher quality of life, and lower levels of emotional distress. The revised CBI may be useful in research (e.g., clinical trials) and in clinical settings to tailor therapies for patients and survivors based on the assessment of strengths and weaknesses in coping strategies.
ABSTRACT
Discovering exoplanets orbiting young Suns can provide insight into the formation and early evolution of our own solar system, but the extreme magnetic activity of young stars obfuscates ...exoplanet detection. Here we monitor the long-term magnetic field and chromospheric activity variability of the young solar analogue V889 Her, model the activity-induced radial velocity variations, and evaluate the impacts of extreme magnetism on exoplanet detection thresholds. We map the magnetic field and surface brightness for 14 epochs between 2004 and 2019. Our results show potential 3–4 yr variations of the magnetic field that evolves from weak and simple during chromospheric activity minima to strong and complex during activity maxima but without any polarity reversals. A persistent, temporally varying polar spot coexists with weaker, short-lived lower-latitude spots. Due to their different decay time-scales, significant differential rotation, and the limited temporal coverage of our legacy data, we were unable to reliably model the activity-induced radial velocity using Gaussian Process regression. Doppler Imaging can be a useful method for modelling the magnetic activity jitter of extremely active stars using data with large phase gaps. Given our data and using Doppler Imaging to filter activity jitter, we estimate that we could detect Jupiter-mass planets with orbital periods of $\sim$3 d. A longer baseline of continuous observations is the best observing strategy for the detection of exoplanets orbiting highly active stars.
Abstract
Background
Comorbid disease in cancer patients can substantially impact medical care, emotional distress, and mortality. However, there is a paucity of research on how coping may affect the ...relationship between comorbidity and emotional distress.
Purpose
The current study investigated whether the relations between comorbidity and emotional distress and between functional impairment and emotional distress were mediated by three types of coping: action planning (AP), support/advice seeking (SAS), and disengagement (DD).
Methods
Four hundred and eighty-three persons with cancer completed a measure of functional impairment (Sickness Impact Profile), the Checklist of Comorbid Conditions, the Brief COPE, the Hospital Anxiety and Depression Scale, the Quality of Life Assessment for Cancer Survivors (Negative Feelings Scale), and the Distress Screening Schedule (Emotional Distress Scale). The latter three measures were used to form a latent construct representing the outcome, emotional distress.
Results
Model comparison analysis indicated that the model with DD as a mediator had a better fit than models containing AP and SAS. DD mediated the relationship between functional impairment and emotional distress, so that engaging in DD was associated with greater distress. In addition, comorbidity and functional impairment were directly and positively related to emotional distress, but the relation between comorbidity and distress was not mediated by coping type.
Conclusions
Both comorbidity and functional impairment may be associated with distress, but disengagement coping only mediated the relation involving functional impairment and was positively associated with distress. Future studies can investigate whether teaching active coping or adaptive coping (e.g., through mindfulness exercises) can decrease distress in cancer patients, despite functional impairments.
In persons with cancer, having serious comorbid diseases and physical functional impairment was related to emotional distress; in addition, disengagement, the only coping mechanism used for dealing with functional impairment, was also associated with emotional distress.
ABSTRACT
Short-orbit gas giant planet formation/evolution mechanisms are still not well understood. One promising pathway to discriminate between mechanisms is to constrain the occurrence rate of ...these peculiar exoplanets at the earliest stage of the system’s life. However, a major limitation when studying newly born stars is stellar activity. This cocktail of phenomena triggered by fast rotation, strong magnetic fields, and complex internal dynamics, especially present in very young stars, compromises our ability to detect exoplanets. In this paper, we investigated the limitations of such detections in the context of already acquired data solely using radial velocity data acquired with a non-stabilized spectrograph. We employed two strategies: Doppler Imaging and Gaussian Processes and could confidently detect hot Jupiters with a semi-amplitude of 100 m s−1 buried in the stellar activity. We also showed the advantages of the Gaussian Process approach in this case. This study serves as a proof of concept to identify potential candidates for follow-up observations or even discover such planets in legacy data sets available to the community.
Abstract
In the conflict between lightweight design and crash safety of high-strength steel components failure models for crash simulation have to be calibrated precisely. To predict shear failure ...strains in a wide strain rate range shear experiments must be performed from quasi-static up to crash-relevant strain rates of about 100 s
-1
. In particular, asymmetric notched shear tensile specimens have proven useful for this purpose in previous investigations. Using this type of shear specimen, a characterization concept for shear loading in a wide strain rate range is presented for high strength steel sheets of different strength, ductility and sheet thickness in this contribution. Within a round robin test of different laboratories the influence of the degrees of freedom in the clamping area and the free clamping length on the kinematic of the specimens and on the deformation and failure behavior in the shear zone are investigated in detail. The main outcome is that the disadvantages of a fix clamping in terms of shear deformation, shear fracture and homogeneity of the shear zone can be compensated by a large free clamping length. An evaluation method based on digital image correlation (DIC) is presented, which enables an operator- and laboratory-independent determination of shear strains up to failure.
Summary
The collateral ligaments (CL) of the distal interphalangeal joint (DIPJ) are important structures for DIPJ stability. Collateral ligament injuries must be considered in the differential ...diagnosis of foot pain. An accurate examination of the CL‐DIPJ can be performed with an adequate ultrasonographic technique and equipment. This paper describes the technique and normal ultrasonographic images as reference data for the diagnosis and documentation of CL‐DIPJ desmopathies and enthesopathies.
Objective: Psychological interventions can attenuate distress and enhance coping for those with an initial diagnosis of cancer, but there are few intervention options for individuals with cancer ...recurrence. To address this gap, we developed and tested a novel treatment combining Mindfulness, Hope Therapy, and biobehavioral components. Method: An uncontrolled, repeated measures design was used. Women (N = 32) with recurrent breast or gynecologic cancers were provided 20 treatment sessions in individual (n = 12) or group (n = 20) formats. On average, participants were middle aged (M = 58) and Caucasian (81%). Independent variables (i.e., hope and mindfulness) and psychological outcomes (i.e., depression, negative mood, worry, and symptoms of generalized anxiety disorder) were assessed pre-treatment and 2, 4, and 7 months later. Session-by-session therapy process (positive and negative affect, quality-of-life) and mechanism (use of intervention-specific skills) measures were also included. Results: Distress, anxiety, and negative affect decreased, whereas positive affect and mental-health-related quality-of-life increased over the course of treatment, as demonstrated in mixed-effects models with the intent-to-treat sample. Both hope and mindfulness increased, and use of mindfulness skills was related to decreased anxiety. Conclusions: This treatment was feasible to deliver and was acceptable to patients. The trial serves as preliminary evidence for a multi-component intervention tailored to treat difficulties specific to recurrent cancer. The blending of the components was novel as well as theoretically and practically consistent. A gap in the literature is addressed, providing directions for testing interventions designed for patients coping with the continuing stressors and challenges of cancer recurrence.
Little attention has been given to assessing the importance of self-care and communication in the caregiving setting, especially caregiving for those who are terminally ill. The Caregiver Inventory ...(CGI), a measure of self-efficacy for caregiving that includes these two dimensions, was subjected to psychometric analyses.
One hundred and thirty-three primary caregivers completed the CGI; of those, 81 also completed the Perceived Stress Scale (PSS), Caregiver Burden Inventory (CBI), and a measure of caregiver tasks (ADLR-CG). Based on home visits, social workers also rated the caregiver tasks required (ADLR-SW). Exploratory Factor Analysis, as well as reliability and validity analyses were conducted.
Fit indices in M + I (V. 5.1) indicated a four factors solution: Managing Medical Information (α = 0.64), Caring for Care Recipient (α = 0.78), Caring for Oneself (α = 0.88), and Managing Difficult Interactions/Emotions (α = 0.76). The CGI was highly negatively related to stress (PSS, r = -0.54, p = 0.001) and burden (CBI, p = -0.37, p = 0.001); ADLR-CG was related to burden (r = 0.43, p = 0.001) but not stress. In regression and relative importance analyses, Care of Oneself and Managing Difficult Interactions/Emotions emerged as equal in terms of having the strongest and most robust negative relationships with stress and burden.
Results suggest that the CGI is a reliable and valid measure of self-efficacy for caregiving, and indicate the importance of self-efficacy for self-care and for managing difficult communication in successfully navigating the demands of caregiving for terminally ill persons.
