Noncompliance in hemodialysis patients as measured with the MBHI

Abstract

Fifteen patients beginning maintenance hemodialysis due to renal failure were administered the Millon Behavioral Health Inventory, the Family Environment Scale and Beck Depression Inventory at the outset of treatment. They were then followed regarding their compliance with fluid, diet and medication, using weight change and serum potassium and phosphorus levels. Statistically significant differences were found on independence/dependence conflicts and between patients showing at least moderate noncompliance with weight and/or phosphorus limitations. Significantly higher levels of depression were associated with consistently poorer compliance patterns.     

Perfectionism and health: A mediational analysis of the roles of stress,social support and health-related behaviours

This study tested a model derived from personality theory in which perceived stress, perceived social support, health-risk and health-promotion behaviours mediate the relationship between perfectionism and perceived physical health. A sample of 538 undergraduate students completed a web-based survey assessing multi-dimensional perfectionism, perceived stress, perceived social support, health behaviours, physical health and a scale tapping elements of the five-factor model of personality. Analyses that account for the effects of traits from the five-factor model (e.g., neuroticism, conscientiousness and extraversion) indicated that socially prescribed perfectionism was associated with poorer physical health and this association was fully mediated by higher levels of perceived stress and lower levels of perceived social support. Self-oriented perfectionism was related complexly to health such that it was related to poorer health via higher levels of perceived stress, but was also related to better health via higher levels of perceived social support. Our findings illustrate the need for considering key mediators of the link between perfectionism and poor health outcomes.     

Word Memory Test Performance in Children

One-hundred and thirty-five children between the ages of 7 and 18 years were evaluated clinically. Their diagnoses included Fetal Alcohol Syndrome (FAS) or Effects, Schizophrenia, Bipolar Mood Disorder, various neurological diseases, Attention Deficit Hyperactivity Disorder (ADHD), Conduct Disorder, Oppositional-Defiant Disorder and learning disabilities. As part of a comprehensive neuropsychological assessment, the children were given the Word Memory Test (WMT; Green, Allen, & Astner, 1996; Green & Astner, 1995), containing various subtests which measure, respectively, effort and verbal memory. Although age and verbal intelligence are known to affect scores on most ability tests, they were not found to be significant determinants of WMT effort scores. Younger children did not score any lower on the effort subtests than older children. The children scored as well as a group of parents seeking custody of their children and they scored higher than adult patients with mild head injuries. The computerized WMT requires some basic reading skills and some children with lower than a grade 3 reading level scored at a relatively low level on the effort subtests. The current data suggest that most children with at least a grade 3 reading level can pass the WMT using the adult criteria. It is concluded that the WMT is potentially useful in the evaluation of effort during pediatric neuropsychological evaluations. Further research is needed to replicate these findings and to develop child norms for the memory subtests.

Miller's reply to Nelson misses the point because it does not attend to the difference between identifying the truth conditions for a proposition and explaining why those conditions are the ones in which the proposition is true.     

Addressing the struggle to link form and understanding in fractions instruction

Background. Although making explicit links between procedures and concepts during instruction in mathematics is important, it is still unclear the precise moments during instruction when such links are best made. Aims. The objective was to test the effectiveness of a 3‐week classroom intervention on the fractions knowledge of grade 5/6 students. The instruction was based on a theory that specifies three sites during the learning process where concepts and symbols can be connected ( Hiebert, 1984 ): symbol interpretation, procedural execution, and solution evaluation. Sample. Seventy students from one grade 5/6 split and two grade 6 classrooms in two public elementary schools participated. Method. The students were randomly assigned to treatment and control. The treatment (Sites group) received instruction that incorporated specific connections between fractions concepts and procedures at each of the three sites specified by the Sites theory. Before and after the intervention, the students’ knowledge of concepts and procedures was assessed, and a random subsample of 30 students from both conditions were individually interviewed to measure their ability to make specific connections between concepts and symbols at each of the three sites. Results. While all students gained procedural skill (p < .001), the students in the Sites condition acquired significantly more knowledge of concepts than the control group (p < .01) and were also better able to connect fractions symbols to conceptual referents (p < .025). Conclusions. The current study contributes to the literature because it describes when it might be important to link concepts and procedures during fractions instruction.     

The role of outcome inhibition in interference between outcomes: A contingency‐learning analogue of retrieval‐induced forgetting

Current associative theories of contingency learning assume that inhibitory learning plays a part in the interference between outcomes. However, it is unclear whether this inhibitory learning results in the inhibition of the outcome representation or whether it simply counteracts previous excitatory learning so that the outcome representation is neither activated nor inhibited. Additionally, these models tend to conceptualize inhibition as a relatively transient and cue‐dependent state. However, research on retrieval‐induced forgetting suggests that the inhibition of representations is a real process that can be relatively independent of the retrieval cue used to access the inhibited information. Consistent with this alternative view, we found that interference between outcomes reduces the retrievability of the target outcome even when the outcome is associated with a novel (non‐inhibitory) cue. This result has important theoretical implications for associative models of interference and shows that the empirical facts and theories developed in studies of retrieval‐induced forgetting might be relevant in contingency learning and vice versa.     

Measuring Narrative Engagement

Research indicates that the extent to which one becomes engaged, transported, or immersed in a narrative influences the narrative's potential to affect subsequent story-related attitudes and beliefs. Explaining narrative effects and understanding the mechanisms responsible depends on our ability to measure narrative engagement in a theoretically meaningful way. This article develops a scale for measuring narrative engagement that is based on a mental models approach to narrative processing. It distinguishes among four dimensions of experiential engagement in narratives: narrative understanding, attentional focus, emotional engagement, and narrative presence. The scale is developed and validated through exploratory and confirmatory factor analyses with data from viewers of feature film and television, in different viewing situations, and from two different countries. The scale's ability to predict enjoyment and story-consistent attitudes across different programs is presented. Implications for conceptualizing engagement with narratives as well as narrative persuasion and media effects are discussed.     

Distracted by Details: Narrative Influence Following Conflicting Stories

Work on narrative influence has demonstrated that stories can have a strong effect on people's thoughts and attitudes. However, existing research has not addressed how people respond to multiple stories endorsing different conclusions. The current studies examined how reading two conflicting narratives influences people's decisions about a subsequent situation, with particular emphasis on how resemblances between the narratives and the situation moderate the effects. Across two studies, participants read two testimonials that described the successful use of different treatments for a medical disorder. Participants subsequently made treatment recommendations for a patient who resembled one of the testimonials in treatment-relevant ways. The key manipulation was whether the patient also resembled the other testimonial in treatment-irrelevant ways. Both studies found that these distracting, irrelevant similarities led to less appropriate treatment recommendations. The effect on decision confidence, however, was less clear, with some suggestion of both an increase (Study 1) and a decrease (Study 2) in confidence.     

The Role of Cognitive Flexibility in the Spatial Representation of Children's Drawings

Representing the spatial appearance of objects and scenes in drawings is a difficult task for young children in particular. In the present study, the relationship between spatial drawing and cognitive flexibility was investigated. Seven- to 11-year-olds (N = 60) were asked to copy a three-dimensional model in a drawing. The use of depth cues as an indicator of spatial drawing was examined. Furthermore, cognitive flexibility was assessed by three measures: the Wisconsin Card-Sorting Test 64 (reactive flexibility), the Five-Point Test (spontaneous flexibility), and omission/inclusion (representational flexibility). The results revealed significant relationships between all measures of flexibility and the depth cues in children's drawings. However, only spontaneous and representational flexibility turned out to be significant predictors of the spatial drawing score. The results are discussed in light of the specific requirements of spatial representations in drawings.
