Working mechanisms of a web-based self-management intervention for cancer survivors: a randomised controlled trial

Objective: The aim of this study was to investigate whether problem-solving skills and perceived personal control over cancer recovery mediated the intervention effects on depression and fatigue of a web-based computer-tailored intervention for cancer survivors – the Kanker Nazorg Wijzer (Cancer Aftercare Guide).

Design: Patients were recruited through 21 Dutch hospitals (November 2013–June 2014). The mediation model was tested in a randomised controlled trial with an intervention group (n = 231) and a waiting list control group (n = 231).

Main outcome measures: Hypothesised mediators problem-solving skills (SPSI-R) and personal control (IPQ-R) were measured at baseline and 3 months from baseline. Outcomes depression (HADS) and fatigue (CIS) were measured at baseline and 6 months from baseline.

Results: The intervention effects in decreasing depression and fatigue were mediated by personal control. Problem-solving skills did not mediate the intervention effects on depression and fatigue.

Conclusion: While personal control in the control group decreased in the first three months after baseline, levels of personal control within the intervention group were maintained. This effect partially explained the intervention effects on depression and fatigue. The results provide evidence for the relevance of addressing personal control in web-based interventions in order to improve psychosocial well-being in early cancer survivors.     

Statistical Bias and Endorsement of Conspiracy Theories

Previous research proposes that endorsement of anomalous beliefs is associated with proneness to conjunction error. This supposition ignores important differences between belief types. Correspondingly, the present study examined the degree to which components of statistical bias predicted conspiratorial ideation and belief in the paranormal. Confirmatory factor analysis and structural equation modelling revealed that conjunction error was associated with conspiratorial ideation, whilst perception of randomness most strongly predicted belief in the paranormal. These findings opposed the notion that anomalous beliefs, by virtue of possession of common characteristics, relate similarly to conjunction error. With regard to conspiracy, conjunction‐framing manipulations produced only minor variations in relationship strength. This supported the notion that conspiratorial ideation was associated with a domain‐general susceptibility to conjunction error. Framing, however, did influence the relationship between belief in the paranormal and conjunction; whilst paranormal conjunctions were generally easier to solve, performance declined as level of paranormal belief increased.Copyright © 2017 John Wiley & Sons, Ltd.     

Discriminatory Capacities,Russell's Principle,and the Importance of Losing Sight of Objects

What capacities for discrimination must a subject possess in order to entertain singular thoughts? Evans has suggested that a subject must be able to discriminate his referent from all other entities in order to be able to do so; what he calls Russell's Principle. Evans' view has few followers, and he has been repeatedly accused of presenting no argument in its favour. In this paper I present what I take to be Evans' argument. I suggest that he has been misinterpreted as introducing Russell's Principle for the purpose of fixing reference. Rather, he introduces it in order to ensure that our conceptual capacities have the functional complexity to allow for objective thought. I suggest that the logical types of our thought are constituted by their inferential potential and argue that, even though singular thought may be possible without the satisfaction of Russell's Principle, singular thought that forms part of an objective world view is not.     

A “Healthy-Contingencies” Behavioral Intervention

Interventions based on functional analyses may result in better treatment outcomes than those using arbitrary reinforcers. However, functional analyses may be impractical in some situations, or an immediate intervention may be necessary while a functional analysis is being conducted. In these situations, delivering the social reinforcers most commonly identified by functional analyses (attention, access to tangibles, and escape from demands) following appropriate behavior and withholding these events following problem behavior may improve behavior. We assessed the extent to which this type of intervention would improve child behavior with three participants. All participants engaged in moderate to high rates of problem behavior and very little appropriate requesting during baseline, and high rates of appropriate requests and reduced rates of problem behavior during treatment.     

Parents’ Understanding of Genetics and Heritability

Parents have the opportunity to educate their children to facilitate behaviours and lifestyle habits that may prevent or delay genetic disease, or mitigate predispositions within the family. We sought to determine parents’ understanding of genetic knowledge and heritability. Using a quantitative survey methodology 108 volunteer participants were surveyed from a convenience sample of all parents/caregivers within the waiting room of a general children’s outpatient clinic. Results indicated that average genetic knowledge levels were fairly high, with the majority of participants scoring 70–80 % correct on knowledge-based questions. Further, scores were found to be positively correlated with education, but inversely correlated with self-perceived knowledge. This finding suggests that participants with less experience tended to overestimate their knowledge. We suggest that gaps in knowledge of genetics and heritability could be improved by using educational interventions such as media campaigns, provision of informational brochures, or changes to current high school curriculum which would increase exposure to genetics and heritability for both parents and children.     

Black Applicants’ Reactions to Affirmative Action Plans: Influence of Perceived Procedural Fairness,Anticipated Stigmatization,and Anticipated Remediation of Previous Injustice1

This research was conducted to understand why Black applicants might react negatively to affirmative action plans (AAPs) designed to benefit them. Black engineering students (N= 2,480) reacted to 1 of 8 AAPs, to which they were randomly assigned. Two manipulations were used to form the 8 different plans: plan content (eliminate discrimination, recruitment, training, weak preferential treatment) and plan frame (affirmative action vs. diversity). The effect of plan content on job‐pursuit intentions was mediated by perceived procedural fairness, anticipated remediation of injustice, and anticipated stigmatization. Job‐pursuit intentions were related to interactions between perceived fairness and anticipated remediation, between perceived fairness and anticipated stigmatization, and between plan content and respondent experiences with discrimination and racism. Plan frame affected only anticipated remediation of previous injustice. Theoretical and practical implications of these findings are discussed.     

Promiscuous or Confident? Attitudinal Ambivalence Toward Condom Purchase1

This research examined attitudes toward condom purchase. Recent evidence is mixed. While some studies show attitudes have become more positive, other studies suggest that negative attitudes still dominate. Our own research examined the possibility that such attitudes may be ambivalent, meaning that the same individuals may simultaneously hold both positive and negative beliefs about condom purchase. The results confirmed this prediction. Study 1 showed that condom purchase evoked a combination of both negative beliefs about lifestyles and positive beliefs concerning the personal confidence of the consumer. These beliefs had competing effects on more global attitudes toward condom purchase. Specific beliefs about condoms were shown to provide the best indication of. whether participants actually used condoms. Study 2 employed standard measures of attitudinal ambivalence. The results conceptually replicated the finding that ambivalence was greater for those who purchased condoms compared to controls.     

A model to coordinate understanding of active autonomous learning

Family therapy has enthusiastically taken up certain concepts for adult education but has not benefited from the full range of ideas that are now both available and compatible with current epistemologies. Good practice in formulating learning objectives is discussed and the objectives of this article are specified. Areas of psychology that are relevant to adult learning are reviewed, and concepts of adult education that are important in the training of family therapists are considered. A model of a spiral process of learning that has been developed within the Leeds Family Therapy and Research Centre is proposed. The model coordinates the principles of adult learning described in the article and may be used as a framework for considering whether training will achieve its learning objectives as well as allowing people engaged in learning to gain further insight into how they learn. Readers are encouraged to use the principles of active reflective learning during their processing of the article.
