In this project we tested the effectiveness of a theory-based intervention (video, pamphlets, and guided practice session) to increase the use of hearing protection devices (HPDs) among Midwestern construction workers and a national group of plumber/pipefitter trainers. Posttest measures were collected 10-12 months following this intervention. Pender's Health Promotion Model (1987) provided the conceptual basis for development of the training program. A total of 837 high-noise-exposed workers were included in the analysis: 652 regional Midwestern construction workers and 185 national plumber/pipefitter trainers. Effectiveness of the intervention was determined through the sequence of analyses recommended by Braver and Braver (1988) for the Solomon Four-Group Design. Analysis of variance and covariance of postintervention use and intention to use HPDs and a meta-analytic test were done. These analyses indicated that the intervention significantly increased use of HPDs but had no effect on intention to use HPDs in the future. Pretesting had no effect on use. Actual or potential applications of this research include guidance in the development of successful theory-based interventions to increase use of HPDs. [ABSTRACT FROM AUTHOR]

The purpose of this study was to compare multiple indicators of behavior and identify the most viable measure of blue-collar workers' use of hearing protection. Three measures of use were employed: observations, supervisor report, and self-report. Supervisor report was highly discrepant from both self-report and observed use; self-report and observations were highly correlated, and discrepancies between the two were slight. These results suggest that, for this type of measurement, self-report is an appropriate measure and may be the best choice when time and monetary resources restrict measurement to one indicator.

This cross-sectional study examined the association of self-efficacy with neighborhood walking in older adult (mean age = 76.1, SD = 8.34) fallers (n = 108) and nonfallers (n = 217) while controlling for demographic characteristics and mobility. Hierarchical multiple regression indicated that the full model explained 39% of the variance in neighborhood walking in fallers (P < .001) and 24% in nonfallers (P < .001). Self-efficacy explained 23% of the variance in fallers (P < .001) and 11% in nonfallers (P < .001). Neighborhood walking was significantly associated with self-efficacy for individual barriers in both groups. Self-efficacy for neighborhood barriers trended toward significance in fallers (β = .18, P = .06). Fall history did not moderate the relationship between self-efficacy and neighborhood walking. Walking interventions for older adults should address self-efficacy in overcoming individual walking barriers. Those targeting fallers should consider addressing self-efficacy for overcoming neighborhood barriers.

Objective: To determine the extent to which prenatal post-traumatic stress disorder (PTSD) is associated with lower birthweight and shorter gestation, and to explore the effects of childhood maltreatment as the antecedent trauma exposure., Design: Prospective three-cohort study., Setting: Ann Arbor and Detroit, Michigan, United States., Sample: In all, 839 diverse nulliparas in PTSD-positive (n = 255), trauma-exposed, resilient (n = 307) and non-exposed to trauma (n = 277) cohorts., Methods: Standardised telephone interview before 28 weeks of gestation to ascertain trauma history, PTSD, depression, substance use, mental health treatment history and sociodemographics, with chart abstraction to obtain chronic condition history, antepartum complications and prenatal care data, as well as outcomes., Main Outcome Measures: Infant birthweight and gestational age per delivery record., Results: Infants born to women with PTSD during pregnancy had a mean birthweight 283 g less than infants of trauma-exposed, resilient women and 221 g less than infants of non-exposed women (F(3,835) = 5.4, P = 0.001). PTSD was also associated with shorter gestation in multivariate models that took childhood abuse history into account. Stratified models indicated that PTSD subsequent to child abuse trauma exposure was most strongly associated with adverse outcomes. PTSD was a stronger predictor than African American race of shorter gestation and a nearly equal predictor of birthweight. Prenatal care was not associated with better outcomes among women abused in childhood., Conclusions: Abuse-related PTSD may be an additional or alternative explanation for adverse perinatal outcomes associated with low socio-economic status and African American race in the USA. Biological and interventions research is warranted along with replication studies in other nations., (© 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.)

Information is limited about the effects of the availability of over the counter medicines (OTCs) at a worksite on workers' ability to remain at work and the effect on health care utilization. The purpose of this preliminary study was to assess workers' perceptions related to the benefits of having a nurse directed over the counter medication dispensing system (OTCMS) at an automotive manufacturing plant. Fifty-six percent of 257 randomly selected workers who participated in semistructured interviews indicated they used OTCs as the first intervention when at home, and 88% had obtained OTCs from the plant's medical department. The workers were overwhelmingly positive about having an OTCMS available at their worksite. Eighty-nine percent indicated that having OTCs available from the occupational health nurse made it possible for them to stay at work and complete their shift. Not only did the workers find the OTCMS to be an asset in their worksite, but they also highly recommended having an OTCMS available in work settings that do not presently have one in place.

Background: The cognitive capacity to direct attention (CDA) is essential for self-care and independent functioning. Older women may be more vulnerable to fatigue-related losses in CDA following surgery for breast cancer. Normal functional variations in CDA associated with aging might affect attentional responses in older women newly diagnosed with breast cancer, and factors such as extent of surgery or symptom distress might influence CDA over time., Objectives: To examine (a) differences in CDA and symptom distress in older women newly diagnosed with breast cancer as compared to a control group of older women without breast cancer; (b) the pattern of change in CDA and symptom distress from the pretreatment period to 3 months after surgery; and (c) to examine the relationship of CDA with symptom distress and extent of surgery over time., Methods: Women, 55 to 79 years of age, newly diagnosed with breast cancer (N = 47), were assessed with measures of CDA and symptom distress: (a) before surgery, (b) at 2 weeks postsurgery, and (c) 3 months postsurgery. To account for normal variations associated with aging, 48 women of similar age without breast cancer were assessed following a routine screening mammogram and 3 months later., Results: Before treatment, the breast cancer group scored significantly lower than the control group (p < .05) on measures of CDA and higher on symptom distress. Repeated measures ANOVA showed significant main effects of group, but not time, for the measures of CDA and symptom distress with the breast cancer group having worse status than the control group. For CDA only, there was a significant group by time interaction effect (p = .005) so that the breast cancer group showed a gradual gain in CDA over time., Conclusions: Reduced performance in a cognitive function was observed before treatment and found to persist over an extended interval in older women newly diagnosed with breast cancer.

Objective: To prospectively determine whether moderate exercise during pregnancy lowers blood pressure., Study Design: A randomized, controlled trial with one test group and one control group. All subjects have a history of mild hypertension, gestational hypertensive disorders or a family history of hypertensive disorders. Subjects were recruited before 14 weeks' gestation. After four weeks of observation, the subjects were randomly assigned to either the exercise or control group. The exercise group visited the laboratory three times a week for 10 weeks (18-28 gestation weeks) to perform 30 minutes of exercise at Rating of Perceived Exertion level 13., Results: A total of 16 pregnant women (mean age, 30 years) participated. The mean metabolic equivalent during exercise sessions was 4.7 (SD = 0.8). Blood pressure measurements were compared before and after the 10-week exercise period in the two groups. Systolic blood pressures did not change significantly, but diastolic blood pressure (DBP) in the exercise group decreased by 3.5 mm Hg, while that in the control group increased by 1.1 mm Hg. Thus, the pre-post change in DBP differed by 4.6 mm Hg between groups. Exercise treatment reduced the diastolic blood pressure to a near-significant level in the exercise group (t = 2.34, df = 7, P = .052). Percent body fat did not differ between the exercise and control groups either before or after exercise treatment. ANOVA revealed that pregnancy had a significant effect (F(1, 14) = 5.7, P = .03) on increasing the percentage of fat, but exercise treatment did not (F(1, 14) = .18, P = .68). Estimated energy expenditure in overall daily physical activities during the intervention did not differ between the two groups despite the inclusion of exercise., Conclusion: This study detected a strong trend that 10 weeks of moderate exercise lowered the diastolic blood pressure among pregnant women at risk of hypertensive disorders. The reductions were probably due to the effect of exercise itself, not to weight or overall daily physical activity levels.

The purpose of this study was to test a model drawn from the modeling and role-modeling theory depicting relationships among psychosocial resources, perceived stress, and health for undereducated adults. A purposive sample of 171 adults enrolled at an urban adult education center completed several self-report measures: Modified Erikson Psychological Stage Inventory, Basic Need Satisfaction Inventory, Perceived Stress, and Positive Health Index. Based on a structural equation modeling analysis, psychosocial development and basic need satisfaction had significant direct effects on health, with the expected positive signs. Psychosocial development had the strongest direct effect on health and also had a strong direct effect on basic need satisfaction and an indirect effect on health. Support for the hypothesized model has important implications for nursing and other community-based care provider interventions regarding health, including strengthening psychosocial resources., (Copyright 2000 John Wiley & Sons, Inc.)

Background: The authors assessed the dental checkup frequency of adults living in the Detroit tricounty area and identified demographic, access and subjective factors associated with visits to a dentist made not because of a dental problem., Methods: Data are from a 1994 probability-based sample of adults who were interviewed and received an in-home oral examination. The authors used the variables of age, sex, education level, income level, dental insurance status, usual place for care, objective measures of oral health, and subjective assessments of health, pain and dental anxiety to predict the frequency of dental checkups., Results: The authors found that differences in dental checkup behavior were related to demographics, access to dental care, subjective ratings of oral and general health and other self-assessments, and clinical parameters of oral health. In multiple logistic regression analysis considering all variables simultaneously, sex, income, having a usual place for care and level of dental care anxiety were found to be associated with having dental checkups. The authors determined the statistical significance level at P < .05., Conclusions: A total of 69.7 percent of the study population reported having had a dental checkup at least once a year in the past five years. The authors found that four factors associated with infrequent dental checkups: being male, having lower income levels, not having a usual place for care and being anxious about receiving dental care., Practice Implications: Dental health professionals should consider the correlates of dental checkup frequency identified in this study and the usefulness of proposed strategies to increase and sustain regular preventive visitation patterns in their own patient populations.

The purpose of this study was to analyze changes in early adolescents' intimate behaviors and the initiation of sexual intercourse over a one-year time period. The changes are interpreted within the context of recent progress in understanding the development of early adolescents. Public school students in sixth and ninth grades of selected schools in a midwestern industrial city were studied in two waves of data collection. A total of 106 students provided data for the second year, allowing comparisons of their Time 2 with their Time 1 responses. Five of eight intimate behaviors studied increased in frequency during the year. Also, the adolescents' perceived benefits of having sexual intercourse increased and perceived costs decreased during the follow-up year. Increases in the frequency of intimate behaviors but not changes in their perceptions of the benefits and costs predicted whether or not students had initiated sexual intercourse during the follow-up period. These findings support current understanding of early adolescence as a time of incremental learning about intimacy and about sexual relationships. The findings suggest that preventing early sexual intercourse may require understanding the specific behavioral competencies related to healthful development of intimacy. Pediatric nurses can be leaders in providing the necessary counseling and education to young adolescents, their families, and their communities.

Introduction: Consistent use of hearing protection devices (HPDs) decreases noise-induced hearing loss, however, many workers do not use them consistently. Past research has supported the need to use a conceptual framework to understand behaviors and guide intervention programs; however, few reports have specified a process to translate a conceptual model into an intervention., Purpose: The strongest predictors from the Health Promotion Model were used to design a training program to increase HPD use among construction workers., Subjects/setting: Carpenters (n = 118), operating engineers (n = 109), and plumber/pipefitters (n = 129) in the Midwest were recruited to participate in the study., Design: Written questionnaires including scales measuring the components of the Health Promotion Model were completed in classroom settings at worker trade group meetings., Measures: All items from scales predicting HPD use were reviewed to determine the basis for the content of a program to promote the use of HPDs. Three selection criteria were developed: (1) correlation with use of hearing protection (at least .20), (2) amenability to change, and (3) room for improvement (mean score not at ceiling)., Results: Linear regression and Pearson's correlation were used to assess the components of the model as predictors of HPD use. Five predictors had statistically significant regression coefficients: perceived noise exposure, self-efficacy, value of use, barriers to use, and modeling of use of hearing protection. Using items meeting the selection criteria, a 20-minute videotape with written handouts was developed as the core of an intervention. A clearly defined practice session was also incorporated in the training intervention., Conclusion: Determining salient factors for worker populations and specific protective equipment prior to designing an intervention is essential. These predictors provided the basis for a training program that addressed the specific needs of construction workers. Results of tests of the effectiveness of the program will be available in the near future.

This study assessed dental anxiety in adults living in the Detroit tricounty area and identified factors associated with it. The prevalence of dental anxiety was 10.0 percent. Regression analysis revealed six factors associated with dental anxiety: unfavorable attitudes toward dentists, infrequent checkups, dissatisfaction with one's month, small numbers of filled surfaces, being female and lower income. Dentists should be aware of these factors when assessing dental anxiety in their patient populations.

Objective: This study compared the preventive oral health behaviors of African-Americans and whites., Methods: Face-to-face interviews were conducted with a probability sample of 384 African-American and 358 white adults living in the greater Detroit area. Questions focused on brushing, flossing, and dental visits., Results: More than 95 percent of both groups reported brushing daily; however, whites were more likely to brush all teeth, including parts that do not show. Frequency of flossing did not differ between groups. African-Americans, however, were less likely to floss all of their teeth. Whites were more likely than African-Americans to get dental check-ups at least once a year and much less likely to indicate they had never had a dental check-up. African-Americans tended to have less education and lower family income than whites and were more likely than whites to have Medicaid. Race differences in brushing thoroughness and annual check-ups were greatly reduced when income, education, and insurance were controlled statistically., Conclusions: African-Americans are less likely than whites to brush thoroughly, floss thoroughly, and get dental check-ups. These differences are partly traceable to differences in socioeconomic status and access to professional oral health care.

Objectives: The goals of this investigation were (1) to evaluate the Oral Health Status Index in relation to demographic characteristics, socioeconomic status, and preventive behaviors of an adult population; and (2) to understand how individual index components performed as indicators of oral health status compared to the composite index., Methods: The Oral Health Status Index (OHSI) was used on a probability sample of adults, aged 18-93 years, living in the Detroit tricounty area. Data were collected on 509 subjects via in-home dental examinations. Bivariate and multivariate analyses were used to compare the OHSI and its components, including decayed, missing, and replaced teeth, free ends, and moderate and severe periodontal disease measures., Results: The mean OHSI score for subjects was 77.3 (SE = 1.83) with a range of -8.0 to 100.0. In regression analyses, OHSI scores were positively correlated with subjects' education level, self-rated oral health scores, and frequency of dental checkups and negatively correlated with age, nonwhite race, and smoking. Of the index components, missing teeth performed well as an indicator of oral health status. Missing teeth were positively correlated with age, nonwhite race, and smoking and negatively correlated with education level, self-rated oral health, and use of Medicaid. About 53 percent of variance in OHSI scores was explained by the multivariate models, compared to 46 percent for missing teeth., Conclusions: Choosing an indicator of oral health status likely will depend upon the characteristics of the population to be studied. As a composite measure of oral health status, the OHSI performed acceptably; however, missing teeth, an index component, also worked well. Continued evaluation of the OHSI is warranted.

The health promotion model (HPM) was tested as a causal model of construction workers' use of hearing protection (N = 359). Theoretical and exploratory models fit well, with the theoretical model accounting for 36.3% of variance and the exploratory model accounting for 50.6% of variance in hearing protection use. Value of use (benefits of using hearing protection), barriers to use, and self-efficacy were significant predictors in both the theoretical and exploratory models, but perceived health status was a predictor only in the theoretical model. In the exploratory model, where modifying factors were allowed direct relationships with use of hearing protection, two modifying factors--noise exposure and interpersonal influences-modeling--were significant predictors. Results of this test of the HPM are consistent with the revised HPM (Pender, 1996). There were significant direct paths from modifying factors to behaviour. Use of hearing protection was best predicted by behavior-specific predictors, such as perceived barriers to use of hearing protection. Results support the use of the HPM to predict use of hearing protection.

The purpose of this study was to determine how the components of psychosocial adjustment to diabetes predict adherence to nutrition recommendations based on self-reported successful completion of contingency contracts. The relationships between the components of psychosocial adjustment and adherence to nutrition recommendations were examined in a convenience sample of patients with non-insulin-dependent diabetes mellitus participating in a contingency contracting intervention with nurses. Patients completed a standardized instrument, the Diabetes Care Profile, at the time they were enrolled into this randomized clinical trial. High and low levels of adherence to nutrition recommendations were identified by a median split of the number of contingency contracts completed for adherence to nutrition recommendations. Subjects who reported higher regimen adherence and a higher support ratio (received more diabetes-specific social support than desired) were significantly less likely to engage in contingency contracting for adherence to nutrition recommendations.

In this study, the Health Promotion Model (HPM) was used as the basis for a structural equation model of male and female blue collar workers' self-reported use of hearing protection devices (HPDs). Overall use did not differ by gender; in addition, self-efficacy and barriers to use of HPDs were the two best predictors of this behavior for both men and women. Despite the similarities in HPD use and the most important predictors of that use between men and women, the predictive models differed by gender in several ways. Significant predictors of use among men also included age and value of use of HPDs. For women, ethnic status and plant site were additional significant predictors of use. Because the influences of plant site and gender on self-reported use of HPDs could not be separated in this study, further research should address worksite culture and assess differences by gender. Knowledge of these differences will aid development of more effective interventions and may increase the use of hearing protection.

Canonical correlation analyses of a previous dental survey suggested that dental checkups, flossing, and tooth brushing could all be predicted from a single equation. Most theories and research about the influence of beliefs on behavior, however, suggest different behaviors will be best predicted by different behavior-specific measures. The current survey investigated influences on brushing, flossing, and dental checkups in a probability sample of adults in the Detroit tri-county area. Both behavior-specific variables, such as perceived benefits and costs of flossing, and general variables, such as gender, were included as predictors. Canonical correlation analysis indicated three equations were needed to predict the three oral health behaviors. Flossing frequency, for example, was best predicted by confidence in flossing ability and beliefs about the benefits of and barriers to flossing. The results suggest that even these closely related behaviors are best predicted using separate equations that include mostly behavior-specific predictors.

This study assessed patterns of mental health service use over time by patients with posttraumatic stress disorder (PTSD) - as compared with patients with schizophrenia and major depression - with emphasis on the persistence and episodic versus continuous nature of use. Data on utilization were extracted from Veterans Health Administration (VA) administrative data bases. Temporal patterns of use were categorized into intervals of inpatient, outpatient, and no use. PTSD patients used substantial amounts of mental health services, but averaged 2.2 nonuse intervals lasting more than 100 days each, implying that use was episodic. Use of mental health services by patients with PTSD is substantial, persistent, and quite episodic. To the extent that use of services reflects the course of the disorder, the results suggest that remissions are usually followed by relapse, and that absence of symptoms does not mean that the disorder has run its course.

The purposes of this study were to explore the differences between fifth and eighth graders' self-reports of having initiated sexual intercourse and the factors related to their early sexual debuts. The urban sample consisted of African American and white fifth (n = 59) and eighth (n = 169) graders. Among fifth graders 46% and among eighth graders 55% reported they had initiated sexual intercourse. Sexual intercourse was more common than other risk behaviors such as cigarette smoking and drinking. The multivariate analyses indicated that the influences on the early initiation of sexual intercourse were complex. Specifically, gender, use of alcohol, costs (i.e., perceptions of negative consequences), and personal norms (i.e., beliefs about when to initiate sexual intercourse) had no direct influence on having initiated sexual intercourse, but indirectly affected the initiation of sexual intercourse through the frequency of other intimate behaviors. The findings are discussed in terms of gender-specific socialization into sex roles and the need to design risk reduction interventions that incorporate messages from multiple social sources.

Purpose: The Corah Dental Anxiety Scale (DAS) was introduced in 1969 as a brief, valid, and reliable instrument to measure anxiety about dental visits. Since then, changes in language usage and dental practice have rendered the scale outdated. In 1994, Ronis introduced the Dental Anxiety Scale-Revised (DAS-R), a version of the DAS revised to acknowledge the roles of dental hygienists and female dentists in the dental office. The current study was conducted to determine whether the original and revised scales are equivalent., Methods: The study tested the equivalence of the two scales by including both in a questionnaire filled out by 141 male and female college students. Psychometric equivalence was examined by comparing the means, and reliabilities (alphas) of the two scales and by correlating the two scales with each other., Results: Mean scores, variances, and reliabilities of the two versions of the scale did not differ. The Pearson correlation between the two scales was .98., Conclusions: It appears that the DAS-R is psychometrically equivalent to the DAS and can be used in its place whenever more up-to-date wording is desired.

In this study, we used the conceptual Health Promotion Model to identify predictors of hearing protection use among blue-collar workers (N = 504). The strongest predictors were self-efficacy, benefits, value, and barriers. Items in the barriers scale were most strongly correlated with use and had the greatest potential for change. Therefore, items from this scale are being used as the primary basis for development of a training intervention program.

This study examined gender and developmental differences in exercise-related beliefs and exercise behaviors of 286 racially diverse youth and explored factors predictive of exercise. Compared to males, females reported less prior and current exercise, lower self-esteem, poorer health status, and lower exercise self-schema. Adolescents, in contrast to pre-adolescents, reported less social support for exercise and fewer exercise role models. In a path model, gender, the benefits/barriers differential, and access to exercise facilities and programs directly predicted exercise. Effects of grade, perceived health status, exercise self-efficacy, social support for exercise, and social norms for exercise on exercise behavior, were mediated through the benefits/barriers differential. Effect of race on exercise was mediated by access to exercise facilities and programs. Continued exploration of gender and developmental differences in variables influencing physical activity can yield valuable information for tailoring exercise promotion interventions to the unique needs of youth.

The health-promoting lifestyles of blue-collar, skilled trade, and white-collar workers were examined. Specific purposes included determining differences in health-promoting behaviors, especially according to worker category, as well as ethnic identification, age, gender, education, and marital status. A convenience sample of 638 workers in a midwestern automotive components plant completed the Health-Promoting Lifestyle Profile (HPLP) and demographics questionnaire. In a multivariate analysis of variance (MANOVA) including all demographic variables, significant differences were found in the mean scores on subscales of the HPLP by job category (2 subscales), age (3), gender (2), and education (4). Prior to including education in the MANOVA, significant differences were found by job category on 5 subscales of the HPLP. The effects of education eliminated the majority of the effects of job category.

Purpose: The Corah Dental Anxiety Scale was introduced in 1969. Since then, changes in dental practice and language usage have dated the scale. The purposes of this study were to (1) slightly modify the scale, (2) assess its reliability and validity, and (3) develop norms for the revised version. The scale modifications recognized the roles of dental hygienists and female dentists in the dental office. Two variations of the first item also were constructed. One asked about going to the dentist "for a checkup¿; the other asked about going "because of a toothache.", Methods: The revised instrument was included in face-to-face interviews with 662 dentate adults living in the Detroit, Michigan, area. Reliability was estimated by Cronbach's alpha. Validity was examined by correlating the revised scale with another measure of dental anxiety and measures of conceptually related variables., Results: Cronbach's alpha coefficient was 0.82 for the checkup version of the scale, 0.79 for the toothache version, and 0.82 for a scale including both variations of the first item, indicating adequate reliability. Dental anxiety correlated positively with history of dental problems (r = .13, .09, and .10 for the checkup, toothache, and combined versions, respectively), negatively with frequency of preventive dental visits (r = -.28, -.22, and -.25), and positively with another measure of dental anxiety (r = .61, .59, and .62), supporting the validity of the scales., Conclusions: The checkup version of the revised scale is recommended for future use. The Dental Anxiety Scale as modified continues to be a reliable and valid instrument 20 years after its introduction.

The Health Promotion Model (HPM) was tested as a causal model to predict workers' use of hearing protection (N = 645). Measures indicated an excellent fit of the theoretical model. The exploratory analyses found the same cognitive-perceptual factors most important in predicting use. However, in contrast to the theoretical model, two modifying factors (job category and situational factors) had direct effects on use. The hypothesized model accounted for 49.3% of variance and the exploratory models accounted for 50.7% to 52.7% of variance in hearing protection use. Results of testing the HPM are consistent with the recently proposed revision of the model by Pender, Walker, Frank-Stromborg, and Sechrist (1990a, 1990b). The strongest effects on behavior came from the behavior-specific influences and demographic characteristics. Situational factors had a direct effect on the health behavior.

Purpose: It has been recommended that adults brush and floss their teeth daily and have periodic oral health checkups. A study was conducted to determine if those recommendations are followed., Methods: Data were collected during face-to-face interviews with a probability sample of 662 dentate adults residing in the Detroit metropolitan area from August to November 1989. Participants were asked how frequently they brushed, flossed, and had checkups. They were also asked about the thoroughness with which they brushed and flossed, and about the advantages and disadvantages of all three behaviors. Descriptive statistics were calculated., Results: The response rate was 72%. While 97% of subjects reported brushing at least once a day and 32% reported flossing at least once a day, 13% indicated they did not brush all teeth or all parts of teeth, and one-third of those who said they flossed daily did not floss all teeth. Seventy-three percent of respondents reported getting dental checkups at least once a year. For brushing, insufficient thoroughness was more commonly a problem than insufficient frequency., Conclusions: Patient education efforts related to brushing will probably be more effective if they focus on thoroughness rather than frequency. Interventions to increase flossing should probably focus on overcoming skill deficits.

Current recommendations for periodontal health maintenance emphasize toothbrushing, flossing and periodic dental checkups. The purposes of this study were to examine (1) the effects of these practices on periodontal health and (2) the relationships of demographic and socioeconomic variables with these behaviors and with periodontal health. Adults (n = 319) in the Detroit, Michigan tri-county area were asked how frequently they performed the 3 preventive behaviors. Levels of plaque, gingivitis, calculus, and periodontal attachment were then assessed during in-home dental examinations. There were no statistically significant differences in these health measures between those with acceptable and unacceptable brushing behavior. About 20% of the subjects reported acceptable flossing behavior, and these individuals had significantly less plaque and calculus than other participants. Over 3/4 of subjects reported having a dental checkup at least 1 x a year, and these persons were found to have significantly less plaque, gingivitis, and calculus compared to less frequent attenders. Acceptable brushing behavior was not associated with any particular demographic or socio-economic characteristic, while differences in acceptable flossing behavior were found among age groups. Frequencies of yearly dental checkups varied significantly within every demographic and socioeconomic characteristic.

Measurements of patients' perceptions of the benefits, costs, and risks of orthognathic treatment are needed to assess the utility of alternative treatments, and to assess and improve patient education to make informed decisions. A two-part study was conducted to develop and evaluate measures assessing patients' perceptions of the benefits and risks of orthognathic surgery in comparison to an orthodontics-only approach or no treatment. The first part of this study included 49 patients who had completed orthodontics and orthognathic surgery and 34 patients considering orthognathic surgery. All patients were asked to complete an open-ended telephone questionnaire about their perceptions of the benefits and risks of orthognathic surgery and of alternative options. Patients' answers were sorted into categories, and the second part of this study included a closed-form written questionnaire to assess the perceived likelihood of possible outcomes in each category. Reliability of the questionnaire was assessed using Cronbach's alpha coefficient of internal consistency reliability. Cronbach's alpha ranged from 0.74 to 0.91 when the instrument was used to assess either overall benefits or risks of orthognathic surgery, orthodontics only, or no treatment, indicating acceptable reliability for each of these uses. Subscales concerning more narrowly defined aspects of benefits and risks were less reliable than the overall scales.

A survey was conducted to identify (a) factors that influence preventive dental behaviors and (b) target groups for interventions. Data were collected in face-to-face interviews with a probability sample of 662 dentate adults living in the Detroit tricounty area. The interviews included questions about demographic and socioeconomic variables and about three preventive behaviors: brushing, flossing, and preventive dental visits. All behaviors were positively associated with socioeconomic status. Females were more likely than males to perform each of the behaviors at the recommended frequency. The behaviors were only weakly associated with age. Whites were more likely than nonwhites to make regular dental visits, but frequency of brushing and flossing did not vary substantially across racial groups. The impact of race on frequency of dental visits was reduced when socioeconomic status was statistically controlled. Findings suggest that socioeconomic status, race, and sex remain important considerations when planning dental health education or other interventions.

We combined the health belief model with the theory of subjective expected utility to derive hypotheses about the relations among health beliefs and preventive decisions. The central implication of this combination of theories is the importance of conceptualizing, measuring, and communicating about health threats in ways that are clearly conditional on action. It is important to distinguish, for example, between how susceptible to a disease a person thinks he or she would be if that person were and were not to take a preventive action. An experimental study of judgments about a hypothetical preventive action was conducted to test many of the theoretically derived hypotheses. A correlation study of dental flossing behavior was conducted to test the hypotheses as they apply to overt behavior rather than to judgment. Results of both studies supported most of the tested hypotheses, especially those related to the conditional conceptualization of health threats. Implications for theory, research methods, and practical applications are discussed.

Researchers from the Michigan Health Care Education and Research Foundation, a research affiliate of Blue Cross and Blue Shield of Michigan, compared three focused utilization review (UR) strategies to determine which method most effectively and efficiently identifies nonacute inpatient hospital admissions. Intensity, Severity, Discharge-Appropriateness (ISD-A) criteria were used to identify nonacute admissions in 8,973 cases in 73 Michigan hospitals. Significant proportions of nonacute admissions were found in medical, psychiatric, and substance abuse cases; surgical admissions had the lowest rates. Strategies involving the concentration ratio were most effective at indicating potential efficiency gains. Focused UR on Diagnosis-Related Groups (DRGs) with nonacute rates greater than 15% captured 41% of admissions and accounted for 85% of nonacute admissions, 85% of nonacute days, and 80% of potential dollar savings. This suggests that UR efforts focused primarily on DRGs with high nonacute rates would significantly improve the efficiency and effectiveness of the overall UR process.

Health care costs and utilization by salaried employees and their dependents at a large self-insured midwestern industrial manufacturing corporation were analyzed for the year before employees were first offered a triple option choice. Members had the option of retaining traditional Blue Cross and Blue Shield of Michigan (BCBSM) coverage or switching to either a number of health maintenance organizations (HMOs) or a number of preferred provider organizations (PPOs). Members who switched to HMOs or PPOs were generally younger and had lower average expenses and utilization rates than those who retained the traditional BCBSM plan. The results suggest that a selection bias does occur in this population, as lower cost members were more attracted to the HMOs and PPOs than were more expensive members. Implications for the corporation as well as for the drive toward managed care alternatives are discussed.

A study was conducted to determine which Major Diagnostic Categories (MDCs) accounted for most of the nonessential hospital admissions in 73 Michigan hospitals in 1986. The Intensity, Severity, Discharge-Appropriateness (ISD-A) criteria set was used to identify nonessential admissions. Large concentrations of nonessential admissions were found in medical, psychiatric, and substance abuse cases; surgical admissions had low rates of nonessential hospitalization. Focusing utilization review on MDCs with nonessential rates exceeding 15% results in an examination of 44% of admissions, while capturing 77% of nonessential admissions and 73% of potential dollar savings. Implications for UR activities are discussed.
