Occupational attainment, smoking, alcohol intake, and marijuana use: ethnic-gender differences in the CARDIA study

OBJECTIVES

To evaluate the prospective interrelationship of smoking, alcohol intake, marijuana use, and educational and occupational attainment of Black and White young adults.

METHODS

Logistic or mixed model linear regression were used to evaluate relationships between self-reported substance use, ethnicity, gender, college graduation, and four measures of occupational attainment.

RESULTS

College graduation in the next 10 years was negatively associated with smoking and marijuana use, but not daily alcohol consumption in all ethnic and gender groups. In Whites, marijuana use was associated with less prestigious occupations and lower family income, while smoking was unrelated and moderate daily drinking was positively associated. In Blacks, marijuana use was generally unrelated to occupational measures, while smoking and daily alcohol consumption were negatively associated.

CONCLUSIONS

Relationships between smoking, marijuana use, daily drinking, and occupational attainment were not universally negative in this age group. Substance use, particularly smoking, is associated with reduced occupational attainment in Blacks compared with Whites after considering sociodemographic factors potentially limiting educational progression and occupational attainment.

On the reliability of implicit and explicit memory measures

Functional dissociations between implicit and explicit memory tests often take the form of large differences between groups or experimental conditions (e.g., amnesics and controls, elderly and younger persons, or persons learning with and without a distracting secondary task) when performance is assessed using explicit memory tests, whereas no difference is observed with implicit memory tests. We argue that the interpretation of such dissociations in terms of the memory processes or systems involved in performance is problematic because the same data pattern would emerge as a result of a mere methodological artifact, that is, the situation that implicit memory tests have low reliability whereas explicit memory tests are fairly reliable measurement instruments. We present reasons for such a reliability difference, and we demonstrate it empirically in Experiments 1a, 1b, and 2. However, our analysis also shows, and Experiment 3 confirms empirically, that implicit memory tests need not necessarily be less reliable measurement instruments than explicit memory tests.

Methodological issues in workplace substance abuse prevention research

Substance abuse among working adults represents billions of dollars in preventable health care costs and industry financial loss. Therefore, it is imperative to develop and test effective substance abuse prevention programs for the workplace. However, applied workplace substance abuse prevention research is fraught with numerous methodological challenges. This article highlights a number of these challenges, which include (1) reaching a broad audience with prevention messages, (2) handling the concerns of the employer, (3) collecting substance use data in the workplace, (4) accessing and using records-based data, and (5) linking survey and records-based data. Using examples from the authors' ongoing research assessing a workplace health promotion and substance abuse prevention program, funded by the Substance Abuse and Mental Health Services Administration's Center for Substance Abuse Prevention, the authors address these challenges.

Integration of computer-assembled digital images and text data as evidence for the oncological record

Digitally created visual images of pertinent patient data have been integrated with text information to formulate a visual evaluation and summary sheet (VESS) using computer processing. The VESS incorporates images of a patient's physical appearance, radiological images, pharmacokinetic graphs, and text information into a 1-page document of the patient's condition. Thus, computer processing of digital images and other information helps to refine patient data presentation, analysis, interpretation, and communication. This form of data management is especially valuable in oncological research, where clinical trials demand rapid, ongoing assessment of results and analysis of large amounts of data. The VESS is an effective mechanism for monitoring both the progress of individual patients and the endpoints of the overall clinical trial.

Job strain, effort-reward imbalance and employee well-being: a large-scale cross-sectional study

This study investigated the effects of the Job Demand-Control (JD-C) Model and the Effort-Reward Imbalance (ERI) Model on employee well-being. A cross-sectional survey was conducted comprising a large representative sample of 11,636 employed Dutch men and women. Logistic regression analyses were used. Controlling for job sector, demographic characteristics (including educational level) and managerial position, employees reporting high job demands (i.e. psychological and physical demands) and low job control had elevated risks of emotional exhaustion, psychosomatic and physical health complaints and job dissatisfaction (odds ratios ranged from 2.89 to 10.94). Odds ratios were generally higher in employees reporting both high (psychological and physical) efforts and low rewards (i.e. poor salary, job insecurity and low work support): they ranged from 3.23 to 15.43. Furthermore, overcommitted people had higher risks of poor well-being due to a high effort-low reward mismatch (ORs: 3.57-20.81) than their less committed counterparts (ORs: 3.01-12.71). Finally, high efforts and low occupational rewards were stronger predictors of poor well-being than low job control when both job stress models were simultaneously adjusted. In conclusion, our findings show independent cumulative effects of both the JD-C Model and the ERI Model on employee well-being and are not significantly different in men and women as well as in young and old people. In particular, high (psychological and physical) efforts and low rewards adversely affected employee well-being. Preliminary findings also indicate excess risks of poor well-being in overcommitted persons suffering from high cost--low gain conditions at work.

Effects of color temperature of fluorescent lamps on body temperature regulation in a moderately cold environment

A study on the effects of different color temperatures of fluorescent lamps on skin and rectal temperatures in a moderately cold environment involving (i) changes in skin temperature of 7 male subjects exposed to an ambient temperature ranging from 28 degrees C to 18 degrees C (experiment I) and (ii) changes in skin and rectal temperatures and metabolic heat production of 11 male subjects exposed to ambient temperature of 15 degrees C for 90 min (Experiment II) was conducted. In Experiment I, the reduction of mean skin temperature from the control value was significantly greater under 3000 K than under 5000 K or 7500 K lighting. In Experiment II, the reductions in mean skin temperature and rectal temperature were respectively greater and smaller under 3000 K than those under 5000 K or 7500 K lighting. However, metabolic heat production was not affected by color temperature conditions. The relationships between morphological and physiological parameters revealed that no significant relation of rectal temperature to body surface area per unit body weight was found only under 3000 K. Furthermore, while the mean skin temperature was independent on the mean skinfold thickness under 3000 K, a significant negative correlation between the rectal and mean skin temperatures was observed. Therefore, body heat loss might be suppressed effectively by increasing the vasoconstrictor tone under a color temperature of 3000 K, and the body shell was dependent only on morphological factors under 5000 K and 7500 K lighting.

The behavioural outcomes of quality improvement teams: the role of team success and team identification

This study investigates the relationship between hospital quality improvement (QI) team success and changes in empowerment, 'organizational commitment, organizational citizenship behaviour' (OCB) and job behaviour related to QI. Data were collected from administrative staff, healthcare professionals and support staff from four community hospitals. The study involved a field investigation with two data collection points. Structured questionnaires and interviews with hospital management were used to collect data on the study variables. High scores were observed for organizational commitment, OCB and job behaviour related to QI when individuals identified with teams that were successful. Low scores were observed when individuals identified with teams that were unsuccessful. Empowerment was positively related to job behaviour associated with QI. It is concluded that participation on QI teams can lead to organizational learning, resulting in the inculcation of positive 'extra-role' and 'in-role' job behaviour.

Reconciling conflicting findings regarding postcessation weight concerns and success in smoking cessation

Correlates of concern about weight gain following smoking cessation and self-efficacy about controlling weight gain were examined in 940 men and 1,166 women who were surveyed on 2 occasions as part of a randomized trial of work-site interventions for smoking cessation. Weight concerns were positively associated with female sex, body weight, dieting for weight control, nicotine addiction, and social encouragement to quit. Bivariate analyses replicated prior findings that elevated weight concerns are associated with a reduced likelihood of quitting smoking, at least in women. Analyses controlling for demographics, nicotine dependence, and social factors replicated prior findings that weight concerns are not negatively related to smoking cessation and that some measures of concern are positively related to cessation. These analyses suggest that conflicting findings found in this literature are due primarily to how weight concerns are defined and whether covariates like nicotine addiction are used in data analyses.

Developing occupational standards: a learning disabilities project

Occupational standards are often seen as cumbersome and inappropriate to a vocational curriculum such as nursing. However, the term fitness for practice is once more being used to focus the minds of educationalists and practitioners in healthcare delivery on the goal in preparing practitioners for the future. The project reported here was guided jointly by staff from a higher education institution and an NHS trust and involved practitioners in designing occupational standards with a view to using them in practice and incorporating them into the preregistration curriculum. The pivotal structure in this process was the focus group which, with tenacity and commitment, designed, developed and structured standards which were realistic and relevant to healthcare delivery.

Evaluating worksite-based interventions that promote safety belt use

OBJECTIVE

The objective of this study was to evaluate the effectiveness of worksite-based interventions in increasing the use of safety belts among employees.

SEARCH STRATEGIES

Using the Cochrane Collaboration search strategy, we searched in electronic databases, review articles, U.S. government documents, and reports of research agencies.

SELECTION CRITERIA

Studies had to be evaluations of worksite-based interventions with a clear description of the program. The outcomes evaluated were the percentage of drivers using their safety belts before and after the intervention and (when possible) after a follow-up period. Safety belt use had to be measured in an objective manner, and a comparison group was necessary.

RESULTS

Forty-eight interventions met the selection criteria. All interventions increased safety belt use among employees, and in 16 the increases were significant (p<0.05). In 15 of the 33 interventions in which follow-up observations were reported, safety belt use continued significantly higher than at baseline. Different strategies (and combinations of strategies) were used across interventions. Interventions incorporating incentives seemed to have stronger effects in increasing safety belt use.

CONCLUSIONS

All reviewed interventions had a positive impact on increasing driver use of safety belts. However, it is important to note the low baseline safety belt use existing at the time when the studies took place, the short-term duration of most interventions, and the short-term follow-up reported (if any). More rigorous research in contemporary worksites is needed.

Substance abuse intervention for health care workers: a preliminary report

The Workplace Managed Care Cooperative Agreement project targets 3,300 health care professionals in hospital, specialty clinic, and primary care settings located in metropolitan New Mexico communities. This project will evaluate whether enhancements to existing substance abuse prevention/early intervention programs can prevent the onset of risky drinking, reduce prevalence of risky drinking, better identify employees who abuse alcohol and drugs, and improve employee wellness. This article describes one such enhancement (Project WISE [Workplace Initiative in Substance Education]), implemented at Lovelace Health Systems. Project WISE includes relatively low-cost elements such as substance abuse awareness training, information on how to reduce drinking, and brief motivational counseling. Evaluation will consist of baseline comparisons of the intervention and comparison sites, a process evaluation, a qualitative analysis using focus groups, and an outcome evaluation using health and work records. Methodological challenges, solutions, and implications for researchers undertaking similar projects are presented.

Machiavellianism: dimensionality of the Mach IV and its relation to self-monitoring in a Spanish sample

The aim of this study was to assess the measurement model of a Spanish version of the Mach IV Scale (Christie, 1970b), used to measure Machiavellianism, and its relation with the Self-Monitoring Scale (Snyder & Gangestad, 1986). 346 undergraduate students (70 males and 276 females) filled in both scales. The results of confirmatory factor analyses showed a four-factor structure to be the most adequate model for the Mach IV, with the following factors: Positive Interpersonal Tactics, Negative Tactics, Positive View of Human Nature, and Cynical View of Human Nature. These results are not in accordance with the original factor structure but are consistent with other authors' findings. A structural model between Machiavellianism and self-monitoring was tested, showing statistically significant paths between interpersonal tactics and one self-monitoring subscale.

Registered nurses, unlicensed assistive personnel, and organizational culture in hospitals

OBJECTIVE

This study investigated "thinking and behavioral" styles that are used to measure the concept of organizational culture among registered nurses (RNs) and unlicensed assistive personnel (UAPs) in acute care hospitals.

BACKGROUND

The Organizational Culture Inventory has been used in numerous industries, including hospitals, to describe aspects of organizational culture in order to better understand and manage change. Evidence shows that nursing unit and hospital culture tends to be "constructive" but little evidence indicates whether workers in different job categories influence the culture differently.

METHOD

This survey was conducted in five tertiary care hospitals on the west coast of the United States. The design is cross-sectional and analytic. A convenience sample was recruited from staff members working at least 20 hours per week in the adult medical-surgical and specialty nursing units. Analyses include descriptive statistics and multiple regression.

RESULTS

Staff members of color, regardless of position, scored higher on the thinking and behavioral styles of approval, avoidance, and competitiveness. Unlicensed assistive personnel, regardless of race or ethnicity, scored higher on the thinking and behavioral styles dependence and opposition.

CONCLUSION

Nurse administrators and managers should be aware of how the addition of unlicensed assistive personnel or people of color can change the culture of the nursing unit or hospital. Explicit management strategies may be necessary to promote employee behaviors that are desirable for patient care and for the organization.

The effects of hand preference and gender on finger tapping performance asymmetry by the use of an infra-red light measurement device

We used an infra-red device to study the effects of gender and handwriting preference on manual asymmetry in tapping rate and intertap variability. Our sample (n=102) consisted of approximately equal number of subjects with respect to gender (52 women and 50 men) and handedness (52 right-handers and 50 left-handers). Data on overall performance indicated that men performed more quickly and regularly than women. The index used for measuring manual asymmetry was the difference between the hands as a proportion of the total. Therefore, the asymmetry index was adjusted to remove the influence of overall performance. The analyses based on asymmetry scores indicated a significant handedness effect: right-handers showed greater manual asymmetries than left-handers for both tapping rate and intertap variability. In addition, right handers exhibited a significant greater asymmetry for intertap variability than tapping rate. Taken together, these data may reflect greater hemispheric differences in right-handers, specially for intertap variability.

Socioeconomic status, hostility, and risk factor clustering in the Normative Aging Study: any help from the concept of allostatic load?

OBJECTIVE

To examine the relationships between socioeconomic status (SES), psychosocial vulnerability (hostility), and allostatic load. Allostatic load refers to the cumulative physiological cost of adaptation to stress.

METHOD

We examined the relationships between SES (as measured by educational attainment), hostility, and allostatic load in the Normative Aging Study, a longitudinal study of community-dwelling men aged 21 to 80 years and free of known chronic medical conditions at entry in the 1960s. In 1986, the revised Minnesota Multiphasic Personality Inventory was administered by mail, from which a hostility measure was derived by summing the scores from three Cook-Medley subscales: Hostile Affect, Hostile Attribution, Aggressive Responding. An index of allostatic load was constructed from data collected during physical exams conducted between 1987 and 1990 (i.e. measures reflecting "wear and tear" on the cardiovascular, endocrine, and metabolic systems). Cross-sectional relationships between education, hostility, and allostatic load were examined in 818 men.

RESULTS

Separate linear regression analyses indicated that lower levels of educational attainment and greater hostility were both associated with higher allostatic load scores (p < .05 and p < .01, respectively). Less education was also associated with higher hostility (p < .001). When allostatic load was regressed simultaneously on education and hostility, the effect of education was attenuated, while hostility (p < .05) maintained an independent effect.

CONCLUSIONS

Our findings suggest that lower levels of education and greater hostility are associated with greater "wear and tear" on the body. The effects of education on allostatic load may be mediated by hostility.

Factors underlying the effect of organisational downsizing on health of employees: longitudinal cohort study

OBJECTIVE

To explore the underlying mechanisms between organisational downsizing and deterioration of health of employees.

DESIGN

Longitudinal cohort study. Data were assembled from before downsizing (time 1); during major downsizing affecting some job categories (time 2); and after downsizing (time 3). Contributions of changes in work, support, and health related behaviours between time 1 and time 2 to the relation between downsizing and sickness absence at time 3 were assessed by multilevel modelling. Mean length of follow up was 4.9 years.

SETTING

Raisio, a town in Finland.

SUBJECTS

764 municipal employees who remained in employment after downsizing.

MAIN OUTCOME MEASURES

Records of absences from work from all causes with medical certificate.

RESULTS

Downsizing was associated with negative changes in work, impaired support from spouse, and increased prevalence of smoking. Sickness absence rate from all causes was 2.17 (95% confidence interval 1.54 to 3.07) times higher after major downsizing than after minor downsizing. Adjustment for changes in work (for instance, physical demands, job control, and job insecurity) diminished the relation between downsizing and sickness absence by 49%. Adjustments for impaired social support or increased smoking did not alter the relation between downsizing and sickness absence. The findings were unaffected by sex and income.

CONCLUSIONS

The exploration of potential mediating factors provides new information about the possible causal pathways linking organisational downsizing and health. Downsizing results in changes in work, social relationships, and health related behaviours. The observed increase in certificated sickness absence was partially explained by concomitant increases in physical demands and job insecurity and a reduction in job control. A considerable proportion of the increase, however, remained unexplained by the factors measured.

Anonymity and Confidentiality in School Surveys on Alcohol, Tobacco, and Cannabis Use

School surveys are currently the most important method of collecting data on alcohol and drug use among youth. Although methodological studies suggest that school surveys yield reliable and valid estimates of substance use among youth, it has been argued that results will be affected by the level of perceived anonymity. Longitudinal research designs raise an important question in this respect since follow-up makes complete anonymity impossible. In fact, responses to such surveys should be regarded as confidential rather than anonymous. This study compares the reported use of cigarettes, alcohol and cannabis between an anonymous, cross-sectional survey and a confidential, longitudinal survey. Both females and males in the confidential survey have a slightly higher rate of non-response for lifetime cannabis use. Furthermore, females tend to be slightly less likely to admit to any use of alcohol and cannabis in the confidential survey, and those who do admit to having used cigarettes and alcohol, report slightly fewer occasions. The correlations between use of cigarettes, alcohol, and cannabis are not affected by this bias. These results add further support to earlier research that has found school surveys to be a robust method of data collection, and suggests that the bias introduced by identification numbers in longitudinal research has limited practical significance.

Applicant self-selection: correlates of withdrawal from a multiple hurdle process

The authors examined applicant self-selection from a multiple hurdle hiring process. The relationships of the selection status of 3,550 police applicants (self-selected out prior to 1 of the hurdles, passing, or failing) and perceptions of the organization, commitment to a law enforcement job, expectations regarding the job, employment status, the need to relocate, the opinions of family and friends, and perceptions of the hiring process were examined. Differences between those who stayed in the process and those who self-selected out were observed in most areas, and those who self-selected out at early stages differed from those self-selecting out at later stages. African Americans' and women's perceptions also differed from the majority group, indicating some of the difficulties an organization faces in attempting to diversify.

Hypnosis and suggestion-based approaches to smoking cessation: an examination of the evidence

This article reviews 59 studies of hypnosis and smoking cessation as to whether the research empirically supports hypnosis as a treatment. Whereas hypnotic procedures generally yield higher rates of abstinence relative to wait-list and no-treatment conditions, hypnotic interventions are generally comparable to a variety of nonhypnotic treatments. The evidence for whether hypnosis yields outcomes superior to placebos is mixed. In short, hypnosis cannot be considered a specific and efficacious treatment for smoking cessation. Furthermore, in many cases, it is impossible to rule out cognitive/behavioral and educational interventions as the source of positive treatment gains associated with hypnotic treatments. Hypnosis cannot, as yet, be regarded as a well-established treatment for smoking cessation. Nevertheless, it seems justified to classify hypnosis as a "possibly efficacious" treatment for smoking cessation.

The five-factor model and driving behavior: personality and involvement in vehicular accidents

Participants completed both the NEO-PI-R personality measure and measures of prior involvement in driving accidents. Significant negative correlations were found between the factor of Agreeableness and the total number of driving tickets received as well as the sum of combined at-fault accidents, not-at-fault accidents, and driving tickets received by participants. Implications and potential future directions for research are discussed.

Effect of cigarette promotions on smoking uptake among adolescents

BACKGROUND

The purpose of this study was to evaluate the association between receptivity to cigarette promotions and smoking uptake in a cohort of adolescents.

METHODS AND MEASURES

This was a prospective cohort study of 480 4th- to 11th-grade students conducted in three rural Vermont K-12 schools. Cigarette use was determined by self-report at baseline, 12 months (survey 2), and 21 months (survey 3). Proportional odds models were used to evaluate smoking uptake as a function of baseline measures of cigarette use, receptivity to cigarette promotions, and confounding factors, including grade, parental education, peer smoking, and family smoking. Adolescents were receptive to cigarette promotions if they owned or were willing to use a personal item bearing a cigarette brand logo [cigarette promotional item (CPI)]. Smoking status was measured using a 6-point ordinal index that combined experience and attitudes: 0 = never smoker/not susceptible to smoking, 1 = never smoker/susceptible to smoking, 2 = puffer (1 cigarette or less in lifetime), 3 = non-current experimenter (2-99 cigarettes in lifetime/none in past 30 days), 4 = current experimenter, and 5 = smoker (> or =100 cigarettes in lifetime).

RESULTS

The 480 students were equally distributed across grade at baseline. Environmental exposure to smoking was high, and 30% were receptive to cigarette promotions at baseline. Higher levels on the smoking index at baseline were associated with higher grade in school, peer smoking, and receptivity to cigarette promotions. One hundred eighty-five students (38.5%) had moved to a higher category on the smoking index by survey 3, of whom 30 had become smokers. Receptivity to cigarette promotions at baseline was significantly associated with higher smoking uptake, with 48.7% of receptive students moving up one or more categories on the smoking index [adjusted proportional odds 1.9 (95% CI 1.3, 2.9)]. Acquisition of receptivity to cigarette promotions was also associated with increased smoking uptake, with those becoming receptive in surveys 2 or 3 having significantly higher odds of progression [3.6 (1.8, 7.0) and 2.9 (1.5, 5.5), respectively] compared with those who did not change. Conversely, those who were receptive at one point but became non-receptive in surveys 2 or 3 had lower odds of progression [0.4 (0.2, 0.9) and 0.5 (0.3, 1.1), respectively].

CONCLUSIONS

This study supports a close linkage between tobacco promotional activities and uptake of smoking among adolescents beyond baseline descriptions of receptivity to cigarette promotions. Over time, the likelihood of smoking uptake is increased when an adolescent acquires a CPI or becomes willing to use one and is decreased when an adolescent who owns a CPI loses it or becomes unwilling to use it. This provides strong evidence that elimination of cigarette promotional campaigns could reduce adolescent smoking.

Action-state orientation: construct validity of a revised measure and its relationship to work-related variables

Data from 6 studies (N = 945) were combined to examine the factor structure and construct validity of J. Kuhl's (1994a) measure of action-state orientation, the Action Control Scale (ACS). Initial confirmatory factor analysis (CFA) of 4 models showed poor fit with the data. Items that did not perform well were dropped, and the 4 CFA models were retested, resulting in support for a 3-factor solution corresponding to the Preoccupation, Hesitation, and Volatility subscales. Regression analyses demonstrated that the revised ACS subscales measure a construct distinct from cognitive ability and personality. The revised subscales showed differential statistically significant relationships with (a) self-regulatory and self-focus variables and (b) job attitudes and ratings of job performance. The authors conclude that action-state orientation is a construct relevant to applied settings and that future research should further examine this construct.

"I knew we would win": hindsight bias for favorable and unfavorable team decision outcomes

This study examined hindsight bias for team decisions in a competitive setting in which groups attempted to outperform each other. It was anticipated that, because of self-serving mechanisms, individuals would show hindsight bias only when decision outcomes allowed them to take credit for their own team's success or to downgrade another team for being unsuccessful. MBA students playing a market simulation game made hindsight estimates regarding the likelihood that either their own or another team would perform well. Consistent with a self-serving interpretation, when decision outcomes were favorable individuals evaluating their own team, but not those evaluating another, showed hindsight bias. When outcomes were unfavorable individuals evaluating their own team did not show hindsight bias, but those evaluating another team did. Discussion focuses on implications of hindsight bias in team decision-making settings.

The effect of organizational structure on perceptions of procedural fairness

This study explored the relationship between 3 dimensions of organizational structure--centralization, formalization, and size--and perceptions of procedural and interactional fairness. Data from 11 organizations (N = 209) indicated that, as predicted, centralization was negatively related to perceptions of procedural fairness, and organizational size was negatively related to interactional fairness. However, contrary to predictions, formalization was not related to perceptions of procedural fairness. Results suggest that organizational structure and design should play a more prominent role in our thinking about organizational fairness.
