Differences in psychosocial factors and fat consumption between stages of change for fat reduction

Abstract

Differences in fat consumption and psychosocial factors between subjects in different trans-theoretical stages of change for fat reduction were studied. Data on fat consumption, self-rated fat intake, attitudes, social support and self-efficacy were collected among a sample of 507 adults. Analysis of variance with Scheffe's multiple-comparison test was used to study differences in these factors between stages of change. Attitudes and social support were most positive among subjects in preparation and action. Self-efficacy expectations were lowest among subjects in contemplation and preparation. Fat consumption was highest among precontemplators hut no substantial differences between other stages were found. It is concluded that subjects in different stages of change differ in psychosocial factors that are regarded as important determinants of behavioral change. Based on these differences it is recommended to develop stage-tailored nutrition education. A majority of subjects in maintenance consumed more fat than is recommended. Therefore, it is suggested that the usually applied staging algorithms might need adjustment for a valid application in nutrition research.     

A Change is Gonna Come: Generational Membership and White Racial Attitudes in the 21st Century

The election of President Barack Obama offers a unique opportunity to test the impressionable‐years hypothesis—the theory of political socialization that predicts that widely experienced political events can have a lasting impact on the political attitudes of individuals who experience that event in their youth, thereby creating a generational distinction. Using data from an original survey embedded in the 2010 Cooperative Congressional Election Study, we examine the racial attitudes of White youth who came of age during Barack Obama's presidential campaign and election to see if those individuals are significantly more liberal on racial attitudes than older generations of Whites. In other words, we look for early evidence that an “Obama generation” has emerged. We find there are indeed early signs of a generational distinction. Members of the “Obama generation” are more strongly opposed to racial resentment, but they exhibit similar levels of opposition to old‐fashioned racism as older cohorts. Additionally, we uncover that the factors that traditionally structure racial attitudes among Whites, most notably contact, education, and residential proximity, work quite differently for members of this generation. We take these findings as initial evidence that Barack Obama's presidency will have a lasting impact on the racial views of a generation of Americans.     

Person–organization (culture) fit and employee commitment under conditions of organizational change: A longitudinal study

This longitudinal study examines how person–organization fit, operationalized as congruence between perceived and preferred organizational culture, relates to employees’ affective commitment and intention to stay with an organization during the early stages of a strategic organizational change. Employees in a large energy company completed surveys before (N = 687) and after (N = 627) the change. We measured perceptions and preferences with regard to four components of organizational culture (human relations, open systems, internal process, and rational goal) derived from the Competing Values Model (Quinn, 1988), as well as affective commitment to the organization and intention to stay. Using polynomial regression and response surface analyses, we found that both perceived culture and culture fit related positively with the criterion variables within and across time. The strongest evidence for relations involving fit was obtained for those components of culture specifically targeted for change. Implications for future research and the management of organizational change are discussed.     

To watch or not to watch: Infants and toddlers in a brave new electronic world

For some time now, questions have been asked about the impact of television and video materials on the cognitive and social development of preschoolers and older children. More recently, these same questions have been asked in relation to the extensive exposure to these media that infants and toddlers are currently experiencing. To answer these questions, we review current research that explicitly targets these concerns and provide new insights into the role these media play in early development.

Stability and predictors of psychopathic traits from mid‐adolescence through early adulthood

High levels of psychopathic traits in youth are associated with multiple negative outcomes including substance misuse, aggressive behavior, and criminality. Evidence regarding stability of psychopathic traits is contradictory. No previous study has examined long‐term stability of psychopathic traits assessed with validated clinical measures. The present study examined the stability of psychopathic traits from mid‐adolescence to early adulthood and explored adolescent factors that predicted psychopathic traits five years later. The sample included 99 women and 81 men who had consulted a clinic for substance misuse in adolescence. At an average age of 16.8 years, the adolescents were assessed using the Psychopathy Checklist: Youth Version (PCL: YV) and five years later using the PCL‐Revised (PCL‐R). Additionally, extensive clinical assessments of the adolescents and their parents were completed in mid‐adolescence. Among both females and males, moderate to high rank‐order stability was observed for total PCL and facet scores. Among both females and males, there was a decrease in the mean total PCL score, interpersonal facet score, affective facet score, and lifestyle facet score. However, the great majority of females and males showed no change in psychopathy scores over the five‐year period as indicated by the Reliable Change Index. Despite the measures of multiple family and individual factors in adolescence, only aggressive behavior and male sex predicted PCL‐R total scores in early adulthood after taking account of PCL:YV scores. Taken together, these results from a sample who engaged in antisocial behavior in adolescence suggest that factors promoting high psychopathy scores act early in life.     

The motivation and inhibition of breaking the rules: Personal values structures predict unethicality

We theorized and tested the relationship of personal value systems with unethical attitudes and behavior. Results from three studies using 16 diverse multi-national samples (N = 107,087) demonstrated the complexity of motivations underlying unethicality. Across contexts and cultures, for attitudes (Study 1 meta-analysis) and behaviors in the lab (Study 2) and in real-life (Study 3), we consistently found that the values theory circumplex structure predicted the inhibition and motivation of unethicality. Unethicality was positively associated with self-enhancement values and negatively associated with self-transcendence and conservation values. However, self-transcendence and conservation values were associated with the inhibition of different types of unethicality. The relationship of openness-to-change values with unethicality was generally positive but the effect size varied depending on context.     

Differential attrition in health behaviour change trials: A systematic review and meta-analysis

Objective: Attrition is a common problem in health behaviour change (HBC) trials. When the degree of attrition differs between treatment conditions, then this is called differential attrition and is regarded as a major threat to internal validity. The primary research question of this study was: how often and to what degree does differential attrition occur in HBC trials?

Design: A systematic review and meta-analysis of a random selection of HBC trials (k = 60). We meta-analysed the relative attrition rates using a random-effects model and examined the relationship between the relative attrition rates and the potential moderators: the amount of human contact in delivery and the intensity of the intervention/control condition, the type of control condition, and the follow-up intensity and duration.

Main outcome measures: Relative attrition rates.

Results: The average attrition rate was 18% (SD = .15; M = .15) in the intervention and 17% (SD = .13; M = .13) in the control conditions. The estimated average relative attrition rate was 1.10 (95% CI: 1.01–1.20, p = .02), suggesting an overall higher attrition rate of 10% in the intervention conditions. This relative attrition rate was not related to any of the potential moderators.

Conclusion: There is indication of a slightly higher amount of attrition on average in the intervention conditions of HBC trials.
