Physical activity levels in young adult Hispanics and Whites: Social cognitive theory determinants

The psychosocial determinants of health-impairing physical inactivity among Hispanic populations have not been well explored nor have systematic comparisons been made with White populations using Social Cognitive Theory (SCT) measures. Three exercise-relevant efficacy measures (task, scheduling, and response efficacy), three exercise-relevant expectancy measures (physical health, psychological health, and self-evaluative), and self reports of activity levels were obtained from 20-year-old male and female Hispanics (n?=?94) and Whites (n?=?94). Activity levels for the two groups were analyzed in separate regression analyses that included the six SCT measures and gender as predictors. The set of seven predictors accounted for 51% of the variance in self-reported activity levels in each analysis. For young adult Hispanics, task efficacy, response efficacy, mental-health expectancies, and self-evaluative expectancies predicted activity level. For young adult Whites, scheduling efficacy and self-evaluative expectancies predicted activity level. Gender was not a significant predictor of activity level for either group. A multivariate analysis of variance indicated that the only SCT predictor on which Hispanics and Whites significantly differed was mental-health expectancies. The results of this study indicate that the psychosocial determinants of exercise are qualitatively different for the two groups and that the determinants of physical activity levels for young adult Hispanics may not be as effective as those of young adult Whites in sustaining lifelong exercise habits. Thus the present study offers a promising strategy for detecting inactivity-related physical- and mental-health risks at an age when lifelong habits of physical activity are still being formed.     

Biases in intuitive reasoning and belief in complementary and alternative medicine

Very little is known about the reasoning underlying beliefs in complementary and alternative medicine (CAM). This study examined whether CAM beliefs can be better explained with intuitive reasoning, paranormal beliefs and ontological confusions of physical, biological and mental phenomena than with 12 variables that have typically been used to explore the popularity of CAM, namely gender, education, income, age, health, desire to control treatment, satisfaction with conventional medicine and world view (unconventional, feministic, environmentalist, exotical and natural). A representative sample of Finnish people (N = 1092) participated in the study. The results showed that intuitive thinking, paranormal beliefs and ontological confusions predicted 34% of the variation in CAM beliefs, whereas the 12 other variables increased the prediction only by 4%. The results help to explain individual, cultural and situational differences in the popularity of CAM and to differentiate between CAM statements that can be scientifically examined from those that cannot.     

Resolving the theory of planned behaviour's ‘expectancy-value muddle’ using dimensional salience

The theory of planned behaviour is one of the most widely used models of decision-making in the health literature. Unfortunately, the primary method for assessing the theory's belief-based expectancy-value models results in statistically uninterpretable findings, giving rise to what has become known as the ‘expectancy-value muddle’. Moreover, existing methods for resolving this muddle are associated with various conceptual or practical limitations. This study addresses these issues by identifying and evaluating a parsimonious method for resolving the expectancy-value muddle. Three hundred and nine Australian residents aged 18–24 years rated the expectancy and value of 18 beliefs about posthumous organ donation. Participants also nominated their five most salient beliefs using a dimensional salience approach. Salient beliefs were perceived as being more likely to eventuate than non-salient beliefs, indicating that salient beliefs could be used to signify the expectancy component. The expectancy-value term was therefore represented by summing the value ratings of salient beliefs, an approach that predicted attitude (adjusted R ²?=?0.21) and intention (adjusted R ²?=?0.21). These findings suggest that the dimensional salience approach is a useful method for overcoming the expectancy-value muddle in applied research settings.

Abstract

Recent theoretical and empirical research has challenged the assumption of health psychologists employing social cognitive models that beliefs can confidently be inferred on the basis of questionnaire responses. It is charged that responses to questionnaires are a function of the intelligibility of the items, constructs and theoretical framework to survey participants. To investigate this contention, cognitions specified by Protection Motivation Theory (PMT) were measured with respect to intentions to use a condom and intentions to use dental floss. Three alternative formats of a questionnaire which varied the order of presentation of PMT items were distributed to student samples. Analyses showed that while questionnaire format did not affect the reliability of cognition measures, there was some variation in the significance and strength of correlations between PMT cognitions across formats. Individual differences in social desirability and salience of the target behaviour had small and predictable effects upon reliabilities and intercorrelations. Implications for the measurement of health beliefs and the status of questionnaire responses are outlined and suggestions are made for controlling bias associated with respondents' capacity to “read” a questionnaire.     

Do Cognitive Interview Instructions Contribute to False Beliefs and Memories?

To examine whether exposing people to false events using instructions taken from the cognitive interview creates false beliefs and false memories, we conducted an experiment where participants took part in two sessions. First, they rated how confident they were that they had experienced certain childhood events and their memories of those events; they also rated how plausible they thought the events were. Second, 2 weeks later, participants were exposed to two of three false target events: one high, one moderate, and one low plausibility. For the first event, participants were instructed to either report everything or mentally reinstate the event context. For the second event, participants received both instructions. The third event was the control event about which participants received no instructions. Finally, participants rated their confidence and memories the second time. The results showed that the cognitive interview instructions had little to no effect on the development of false beliefs and false memories. Copyright © 2012 John Wiley & Sons, Ltd.     

Spiritual Development in the Fourth Quarter of Life

SUMMARY

Spirit, the activating or essential principle influencing a person, and body interpenetrate each other but do not dominate each other in predictable ways. Normal aging is neither a failure of the human spirit nor a failure in the body's Biology. The spirit becomes more apparent as a result of spiritual development.

The fourth quarter of life covers age 75 to 100 years. Prior to age 75, the human spirit undergoes significant developmental events: a crisis of meaning which may result in conversion or more commonly stripping or shedding; transitions, including loss of clearly defined roles and loss of the sense that the individual's life makes a difference.

One motif applied by our culture to old age is the “iconic illusion”; however, it is evident that in some respects this motif has limited application to the fourth quarter of life. “Meaning making” is, in fact, enhanced in the fourth quarter of life, given reasonable levels of cognitive health. The desire and ability to make sense out of existence, to draw together an understanding of a meaningful life trajectory, is best done in the fourth quarter of life. The dominant sense of time in the fourth quarter of life particularly facilitates spiritual development.     

The Effects On and Of Depression - An Exploratory Study of Rehabilitation and Secondary Prevention in Coronary Artery Disease

Forty consecutive participants in a comprehensive, behaviourally oriented coronary rehabilitation and secondary prevention program were followed for three years. Changes in depression (as measured with the Beck Depression Inventory) as well as the influence of baseline levels of depression on achieved changes in lifestyle behaviour and on rehabilitation and secondary prevention effects were analyzed. Subjects with moderate levels of baseline depression experienced short-term reductions of depression, which was maintained at the 12-month follow-up. Clinically depressed subjects experienced less positive results, with smaller immediate reductions as well as relapse to baseline levels after 12 months, specifically in non-physical, cognitive-affective depression symptoms. There were, however, no differences in lifestyle changes or in hospital treatment between groups with different pre-treatment depression levels. These results are discussed in relation to earlier research on the detrimental effects of depression on the prognosis of coronary artery disease.     

Intolerance of Uncertainty Mediates the Relation Between Generalized Anxiety Disorder Symptoms and Anger

Previous research has shown that individuals with generalized anxiety disorder (GAD) report elevated anger compared with nonanxious individuals; however, the pathways linking GAD and anger are currently unknown. We hypothesized that negative beliefs about uncertainty, negative beliefs about worry and perfectionism dimensions mediate the relationship between GAD symptoms and anger variables. We employed multiple mediation with bootstrapping on cross-sectional data from a student sample (N = 233) to test four models assessing potential mediators of the association of GAD symptoms to inward anger expression, outward anger expression, trait anger and hostility, respectively. The belief that uncertainty has negative personal and behavioural implications uniquely mediated the association of GAD symptoms to inward anger expression (confidence interval [CI] = .0034, .1845, P_M = .5444), and the belief that uncertainty is unfair and spoils everything uniquely mediated the association of GAD symptoms to outward anger expression (CI = .0052, .1936, P_M = .4861) and hostility (CI = .0269, .2427, P_M = .3487). Neither negative beliefs about worry nor perfectionism dimensions uniquely mediated the relation of GAD symptoms to anger constructs. We conclude that intolerance of uncertainty may help to explain the positive connection between GAD symptoms and anger, and these findings give impetus to future longitudinal investigations of the role of anger in GAD.     

具有类属知识性的思维:群体区别判断过程中的复杂性、有效性、有用性和实质性

类属性思维(stereotypes)在一定的程度上是对群体区别正确反映的类属信仰.类属性思维比我们一般假想的更为复杂.首先,我们在本论文中探讨了在立体性的类属性思维EPA理论框架之下的多维度,即类属性思维的三维度:评估、激活和准确度.同时还特别讨论了类属性思维与具体集体共识的表征特点的图腾信仰之间的密切关系.其次,对于作为人类信仰一部分的类属性思维准确性莫衷一是的研究,我们进行了全面综述,并且本文还仔细考查文化类属性思维,个体类属性思维,个体与群体的判断,准确性评判的标准,和原分析的数据等等,同时进一步表明类属性思维和客观现实性有密不可分的关系.最后,我们指出类属性思维对解释群体和民族的区别非常重要,特别是人的感知的实质性寓于实在的客观群体本身(“感知的同一性”).我们认为,类属性思维的过程,对于高度的实体性和感知的实质性的群体来说,具有深刻影响,况且群体或部落(民族)的图腾也是其群体或民族的实体性的外在表现.尽管我们不可能解决同类属性思维的过程有关的所有争论,但我们所强调的观点是:类属性思维是人类相互影响和生存的有效类属性识别.     

The Impact of Childhood Physical Abuse and Age of Sexual Initiation on Women's Maladaptive Posttraumatic Cognitions

Child abuse survivors often exhibit long-standing maladaptive beliefs. Sexual risk-taking could contribute to the maintenance of such beliefs by reinforcing cognitions that originally resulted from child abuse. In this study, 64 community women, most with elevated posttraumatic stress disorder symptoms, completed measures of childhood abuse, sexual risk-taking, and posttraumatic cognitions. Age of first consensual sexual intercourse mediated the relationship between childhood physical abuse and maladaptive posttraumatic cognitions in adulthood. Thus, age of sexual intercourse initiation might play an important role in women's recovery from childhood physical abuse. Clinicians should consider the possible impact of women's sexual history when challenging their cognitions during trauma-based cognitive behavioral therapy. Further, decreasing risky sexual behavior might partially protect against the negative effects of trauma.
