Does screening for distress efficiently uncover meetable unmet needs in cancer patients

Objectives: We evaluated screening for distress in terms of its ability to uncover unmet need for psychosocial services in cancer patients. Correlates of distress, need for services and met and unmet need for services were investigated.

A Reconsideration of the Self-Compassion Scale's Total Score: Self-Compassion versus Self-Criticism.

The Self-Compassion Scale (SCS) is currently the only self-report instrument to measure self-compassion. The SCS is widely used despite the limited evidence for the scale’s psychometric properties, with validation studies commonly performed in college students. The current study examined the factor structure, reliability, and construct validity of the SCS in a large representative sample from the community. The study was conducted in 1,736 persons, of whom 1,643 were included in the analyses. Besides the SCS, data was collected on positive and negative indicators of psychological functioning, as well as on rumination and neuroticism. Analyses included confirmatory factor analyses (CFA), exploratory factor analyses (EFA), and correlations. CFA showed that the SCS’s proposed six-factor structure could not be replicated. EFA suggested a two-factor solution, formed by the positively and negatively formulated items respectively. Internal consistency was good for the two identified factors. The negative factor (i.e., sum score of the negatively formulated items) correlated moderately to strongly to negative affect, depressive symptoms, perceived stress, as well as to rumination and neuroticism. Compared to this negative factor, the positive factor (i.e., sum score of the positively formulated items) correlated weaker to these indicators, and relatively more strongly to positive affect. Results from this study do not justify the common use of the SCS total score as an overall indicator of self-compassion, and provide support for the idea, as also assumed by others, that it is important to make a distinction between self-compassion and self-criticism.

Personal control after a breast cancer diagnosis : stability and adaptive value

Objective: This longitudinal study aims to gain more insight in both the changes in personal control due to a breast cancer diagnosis, as well as in the stress‐buffering effect of personal control.

Personal control over the cure of breast cancer: adaptiveness, underlying beliefs and correlates

Objectives: Although cognitive adaptation theory suggests that personal control acts as a stress buffer when facing adversity, maladaptive outcomes might occur when control is disconfirmed. The moderating effect of disappointing news on the adaptiveness of personal control over cure in women with breast cancer was examined and contrasted with the effect on the adaptiveness of general control over life. Additionally, the underlying beliefs and correlates of control over cure were explored.

The Tenacious Goal Pursuit and Flexible Goal Adjustment Scales: A Validation Study

The flexible goal adjustment (FLEX) and tenacious goal pursuit (TEN) scales are used regularly in aging research. The current study examined their validity in a sample of 517 women (30-75 years) in multiple ways. Overall, the findings show that the scales do not clearly distinguish between FLEX and TEN. The direction in which the items were formulated was just as important as what was being measured. Moreover, face validity of the inversely phrased items in particular appeared to be weak. On the basis of these findings, the authors recommend a revision of the concept definitions as well as of the items.

Is implementing screening for distress an efficient means to recruit patients to a psychological intervention trial

Psychological interventions show greater efficacy when evaluated with distressed patients. We report on the feasibility of implementing screening for recruiting distressed cancer patients to a randomized controlled trial of problem‐solving therapy (PST), characteristics associated with enrolment, and time investment and challenges of implementing screening.

Immunological Challenges Facing Translation of Alginate Encapsulated Porcine Islet Xenotransplantation to Human Clinical Trials

Transplantation of alginate-encapsulated islets has the potential to treat patients suffering from type I diabetes, a condition characterized by an autoimmune attack against insulin-secreting beta cells. However, there are multiple immunological challenges associated with this procedure, all of which must be adequately addressed prior to translation from trials in small animal and nonhuman primate models to human clinical trials. Principal threats to graft viability include immune-mediated destruction triggered by immunogenic alginate impurities, unfavorable polymer composition and surface characteristics, and release of membrane-permeable antigens, as well as damage associated molecular patterns (DAMPs) by the encapsulated islets themselves. The lack of standardization of significant parameters of bioencapsulation device design and manufacture (i.e., purification protocols, surface-modification grafting techniques, alginate composition modifications) between labs is yet another obstacle that must be overcome before a clinically effective and applicable protocol for encapsulating islets can be implemented. Nonetheless, substantial progress is being made, as is evident from prolonged graft survival times and improved protection from immune-mediated graft destruction reported by various research groups, but also with regard to discoveries of specific pathways involved in explaining observed outcomes. Progress in the latter is essential for a comprehensive understanding of the mechanisms responsible for the varying levels of immunogenicity of certain alginate devices. Successful translation of encapsulated islet transplantation from in vitro and animal model testing to human clinical trials hinges on application of this knowledge of the pathways and interactions which comprise immune-mediated rejection. Thus, this review not only focuses on the different factors contributing to provocation of the immune reaction by encapsulated islets, but also on the defining characteristics of the response itself.

The Impact of Goal Disturbance after Cancer on Cortisol Levels over Time and the Moderating Role of COMT

Due to physical hindrance and time spent in hospital, a cancer diagnosis can lead to disturbance of personally important goals. Goal disturbance in cancer patients has been related to poorer psychological well-being. However, the relation with physiological measures is yet unknown. The purpose of the current study is to examine the impact of goal disturbance on cortisol as a measure of response to stress over time, and a possibly moderating role of a DNA genotype associated with HPA-axis functioning, Catechol-O-Methyl transferase (COMT). We examined the predictive value of goal disturbance on Cortisol Awakening Response (CAR) and Diurnal Cortisol Slope (DCS) over two periods: 1–7 and 7–18 months post-diagnosis, and the moderating role of COMT during these periods. Hierarchical regression analyses showed that goal disturbance 7 months post-diagnosis significantly predicted a steeper CAR a year later. During that period, the slow COMT variant moderated the relation, in that patients reporting high goal disturbance and had the Met/Met variant, had a more flattened CAR. No other significant effects were found. As steeper CARs have been related to adverse health outcomes, and COMT genotype may modify this risk, these results indicate that goal disturbance and genotype may be important factors to consider in maintaining better psychological and physical health in the already vulnerable population of cancer patients.

The reciprocal relationship between daily fatigue and catastrophizing following cancer treatment: Affect and physical activity as potential mediators

Fatigue is a distressing symptom many cancer patients experience even after completion of treatment. Although theory and empirical evidence indicate that negative cognitions perpetuate fatigue after completion of treatment, insight into how this process unfolds in daily life is limited. This study used an intensive longitudinal design to investigate the reciprocal relationship between catastrophizing and fatigue in daily life and whether affective and behavioral processes mediate these relationships.

Associations of daily partner responses with fatigue interference and relationship satisfaction in colorectal cancer patients.

Objective: This study investigates the associations of daily partner responses toward patient’s fatigue and well behavior with patient’s fatigue interference and relationship satisfaction. The moderating effect of fatigue severity was also examined. Method: In an intensive longitudinal design, patients treated for colorectal cancer and their partners (n = 101 dyads) completed diaries for 14 days. Patients and partners reported on partner responses toward patient’s fatigue behavior (e.g., resting), partner responses toward patient’s well behavior (e.g., being active), and fatigue severity. Patients also indicated their fatigue interference and relationship satisfaction. Multilevel modeling was applied to assess within-person main and interaction effects. Results: Patient-reported solicitous responses toward fatigue behavior and negative responses toward well behavior were associated with increases in fatigue interference, while facilitative responses toward well behavior were associated with a decrease in fatigue interference. The latter two associations were intensified on days patients reported relatively high fatigue. Solicitous responses toward fatigue behavior and facilitative responses toward well behavior were also associated with increases in relationship satisfaction. Punishing responses toward fatigue behavior were associated with a decrease in relationship satisfaction, especially on days patients reported higher fatigue. Models using partner reports largely confirmed the main effects of partner responses on fatigue interference and relationship satisfaction but failed to reproduce the moderating effect of fatigue. Conclusions: Daily partner responses appear to impact patients’ fatigue adjustment, especially on days patients experience high fatigue levels. Only facilitative responses toward well behavior seem to benefit both patients’ fatigue interference and relationship satisfaction. Couple interventions should guide partners to encourage patients’ well behavior and aid them to correctly estimate patients’ current fatigue severity.
