Cognitive control and consistency in compliance

Abstract

The purpose of this prospective study was two-fold. First, three modes of compliance assessment were used to examine whether renal dialysis patients comply consistently across medical regimens (fluid, potassium, phosphorous, protein) and whether compliance is consistent across mode of assessment (patient self assessment, medical staff ratings, physiological data). Second. a cognitive model predicting fluid compliance was tested to see if it would generalize to predict dietary compliance and medication taking. Patients' self-control perceptions of compliance, staff assessments of compliance, and physiological data were collected prospectively for 85 end-stage renal disease (ESRD) patients. Results indicated substantial consistency across medical regimen depending on the mode of assessment; staff assessment showed the most consistency, followed by patients' self-assessments and lastly by physiological data. Despite this consistency across medical regimens, the cognitive-control model only predicted fluid compliance; the model failed to explain dietary and medication compliance. Reasons and implications for these results are discussed.     

Social support and cardiovascular responding to laboratory stress: Moderating effects of gender role identification,sex, and type of support

The objective of the present study was to examine moderating effects of gender role identification, sex, and type of support on the buffering role of social support on cardiovascular responses. We hypothesized that (a) gender role identification, more than sex, would moderate the effect of social support and (b) to obtain optimal attenuating effects of social support, type of support provided should match type of support preferred in terms of one's gender role identification. That is, feminine participants would benefit more from relatively direct support, whereas masculine participants would benefit more from indirect support. Healthy participants (N = 100) performed a psychological stressor in the presence of a friend, after mental activation of a friend, or alone. Results revealed no moderating effects of gender role identification whether or not in combination with type of support. Nevertheless, results demonstrated an attenuating effect of mental support on heart rate and cardiac output in men. It is concluded that pathways linking social relationships and health may differ between women and men.     

The Test of Variables of Attention (TOVA): Internal Consistency (Q1 vs. Q2 and Q3 vs. Q4) in Children with Attention Deficit/Hyperactivity Disorder (ADHD)

The internal consistency of the Test of Variables of Attention (TOVA) was examined in a cohort of 6- to 12-year-old children (N = 63) strictly diagnosed with ADHD. The internal consistency of errors of omission (OMM), errors of commission (COM), response time (RT), and response time variability (RTV) of different test conditions (stimulus infrequent condition [Q₁ vs. Q₂] and stimulus frequent condition [Q₃ vs. Q₄]) was assessed via correlation analyses. All TOVA index scores under investigation assessing its internal consistency exhibited statistically significant correlations. All correlations fell in the moderate-high range.     

Cronbach's Alpha: Review of Limitations and Associated Recommendations

This paper discusses the limitations of Cronbach's alpha as a sole index of reliability, showing how Cronbach's alpha is analytically handicapped to capture important measurement errors and scale dimensionality, and how it is not invariant under variations of scale length, interitem correlation, and sample characteristics. In addition, the limitations and strengths of several recommendations on how to ameliorate these problems were critically reviewed. It was shown that the reliance on Cronbach's alpha as a sole index of reliability is no longer sufficiently warranted. This requires that other indices of internal consistency be reported along with alpha coefficient, and that when a scale is composed of large number of items, factor analysis should be performed, and appropriate internal consistency estimation method applied. This approach, if adopted, will largely minimize and guard against uncritical use of Cronbach's alpha coefficient.     

Causal Attribution: Analysis of Patterns and Influencing Factors Among Learners at a Higher Education Institution

The study explored the academic patterns and implications of academic attributions made by students who had been given test feedback at a higher learning institution in Zimbabwe. A random sample of 8 (female = 4; male= 4; mean age = 21.9, passed a test = 4; failed the test = 4) participants was purposefully selected from a class of second year students majoring in psychology and human resources management. Audio-taped semi-structured interviews were conducted to collect data. Thematic content analysis was used to analyse data. Results indicate that culture and gender moderate academic causal attributions.     

Development and Validation of the Xhosa Translations of the Beck Inventories: 2. Item Analysis,Internal Consistency and Factor Analysis

The Beck Depression Inventory-II (BDI-II), the Beck Anxiety Inventory (BAI), and the Beck Hopelessness Scale (BHS) were translated into Xhosa, a language widely spoken in South Africa to yield translated scales referred to as the XBDI-I (Xhosa BDI-II), the XBAI (Xhosa BAI) and the XBHS (Xhosa BHS). These scales were administered to a sample of 122 Xhosa respondents which included students and patients. The psychometric properties of the translated scales were comparable to those of the original English versions. Measures of internal consistency were as high as those for the validation studies in the USA and good item-scale correlations were obtained. This suggests that the translation yielded clinically useful scales which tap symptoms that are largely culturally universal.     

An analysis of coping profiles and adjustment in persons with rheumatoid arthritis

This study examined dispositional and situative antecedents of vigilant and avoidant coping behavior. Seventy-two subjects were classified in coping style on the basis of their responses to the vigilance and cognitive avoidance scales of the Mainz Coping Inventory (MCI, Krohne, 1989), and alternatively, on their trait anxiety and defensiveness scores (cf. Weinberger, Schwartz, & Davidson, 1979). In a subsequent laboratory task, subjects were exposed to various conditions of predictability of an aversive event. In anticipation of an aversive loud tone, coping behavior was operationally defined as choosing to listen either to a warning channel (i.e., vigilance) or instead to music (i.e., avoidance). Probability of occurrence of a warning signal while listening to the warning channel varied across trials, being either 0%, 33%, 66%, or 100%. Subjects were exposed to each level and were informed about the respective probability in advance. In general, listening to the warning channel increased with an increase in the probability of the warning signal. However, four groups of subjects who differed in their pattern of coping behavior across trials were observed: rigid-avoidant copers (always listening to music), rigid-vigilant copers (always monitoring the warning channel), flexible copers (switching from music to warning channel with increasing probability of warning), and inconsistent copers (vacillating between music and warning channel regardless of probability of warning). Coping style classifications did not show substantial associations with coping behavior. However, subjects demonstrating the inconsistent coping pattern scored high on trait anxiety.     

Coherence and transituational generality in coping: The unity and the diversity

Abstract

We investigated the transituational coherence of coping strategy use by collecting coping data on multiple occasions, and assessing the effects of aggregation over varying numbers of occasions. Study 1 examined the effects of aggregating daily coping reports over three- and six-day periods. Study 2 extended the results of Study 1 by assessing the extent to which aggregation increased the correlation between a dispositional coping measure and daily coping reports. Both studies strongly supported the hypothesis that aggregation would enhance the consistency of coping preferences, suggesting some degree of coherence within the domain of coping strategy used. Aggregated coping reports correlated with each other at significantly higher levels (ranging from 0.46 to 0.77 in Study 1 and from 0.65 to 0.95 in Study 2), than unaggregated coping reports (ranging from ?0.12 to 0.30 in Study 1 and from 0.12 to 0.53 in Study 2). Study 2 also showed that aggregated daily reports were better predictors of subsequent coping than scores derived from a standard dispositional coping survey.

This is a study which investigates some difficulties people with schizophrenia have in the long term; looks at some of the psychoanalytical theories concerning the difficulties they have in keeping an internal caring maternal imago; the consequences for them; how the NHS can help by providing an external caring maternal imago.     

The Role of Schools in Building the Resilience of Youth Faced with Adversity

This study explored factors related to risk, resilience and health amongst South African teenagers. Grade nine students (N = 472; males = 210, females = 262, age range = 12 to 18 years) at seven schools in the Western Cape participated in the study. The California Healthy Kids Survey, which includes risk and resilience modules, was utilized. Focus group interviews were also conducted with the students to determine their needs and support at school. Questionnaires relating to the health promoting schools framework were administered to teachers. Quantitative and qualitative research methodologies were employed. The results indicated that the students were engaged in a variety of risk behaviors that threatened their well-being and that their external and internal assets were limited. A multi-faceted approach to reducing risk and enhancing resilience, involving family, peer, school and community support within a health promoting schools framework, is advocated.
