Integration of two models, or dominance of one?

Hobbis and Sutton attempted to integrate Cognitive Behavior Therapy (CBT) with the Theory of Planned Behavior (TPB). The possibility of such an integration portends exciting opportunities since behavioral interventions have had limited impact on behavior change. The integration, however, may more easily occur if Hobbis and Sutton had selected a formulation of the TPB that incorporated emotional variables, which is a primary focus of CBT. Furthermore, more work may be necessary to integrate the specific cognitive constructs between CBT and the TPB. Empirical research will be necessary to validate that the integration occurred in a meaningful way.

A physician fitness program: enhancing the physician as an "exercise" role model for patients.

BACKGROUND: Physically active physicians are more apt to counsel patients about exercise. PURPOSES: The purpose of this study was to determine the effect of a physician fitness program on resident physician cardiovascular fitness, physical activity behavior/stage of change, and physical activity counseling behavior/attitudes. METHODS: A prospective, intervention study with measurements at baseline (before intervention), 3 months (immediately after intervention), and 6 months (3 months after intervention) evaluated a multifaceted exercise program for 48 internal medicine residents. Resident physician cardiovascular fitness, energy expenditure, physical activity stage of change, knowledge, attitudes, and counseling behavior were measured. RESULTS: Resident physician fitness significantly declined over time (baseline VO(2)-170 = 29.1 ml/kg/min, first follow-up VO(2)-170 = 27.3 ml/kg/min, and second follow-up VO(2)-170 = 26.2 ml/kg/min; p = .001). Although there was no change in overall energy expenditure, the number of resident physicians in the precontemplation or contemplation stage of change significantly declined with a corresponding increase in the number in a "higher" stage of change at first (p = .0034) and second follow-up (p = .024). There was a nonsignificant increase in self-reported patient counseling. Resident physician counseling confidence and perceived success significantly improved at first follow-up only (p = .01 and p = .03, respectively). CONCLUSION: Although resident physician fitness and energy expenditure did not improve after intervention, a significant improvement in resident physician physical activity stage of change and attitudes toward patient counseling was noted. Randomized controlled trials are needed to confirm whether these changes are attributable to the intervention.

Physical activity and health enhancing dietary behaviors in young adults: Bogalusa Heart Study.

BACKGROUND: Obesity results from energy imbalance. This study used data from the Bogalusa Heart Study to examine relationships between the dietary and physical activity behaviors of young adults. METHODS: One thousand one hundred ninety-one young adults (76% Euro-American, 24% African-American, 61% female) completed a food frequency questionnaire and reported the location of meals consumed. Physical activity outside of work was assessed using a 5-item Likert scale. Analyses of covariance were used to determine if dietary consumption differed by physical activity level after controlling for ethnicity, BMI, age, and gender. Regression models were used to explore two- and three-way diet, gender, and ethnicity interactions. RESULTS: Consumption of fruit and dairy foods significantly differed (P < 0.05) by activity level with the most active group consuming 0.4 more servings per day for both fruit/fruit juices and dairy. Increased physical activity was significantly associated (P < 0.05) with decreased dietary fat. Increased physical activity was associated with increased consumption of fat among African-American males and decreased consumption of fat among Euro-American males. Euro-American females consumed less energy than the three other ethnic/gender groups. CONCLUSIONS: Increased consumption of fruit, dairy foods, and reduced energy from fat were related with increased physical activity with this relationship differing by gender and ethnicity.

Why combine diet and physical activity in the same international research society?

Research in diet and physical activity in the U.S. started in very different traditions, with behavioral science input being uneven in their development. Investigators and policy makers in Europe have recognized the complementarity of diet and physical activity and incorporated them both under the label Public Health Nutrition. Joining these disciplines internationally offers the opportunity to benefit all, since the problems addressed are human, not specific to any one country.In regard to why combine diet and physical activity, at the biological level, there is reason to believe that diet and physical activity working in concert can remodel physiological structures and processes toward healthful ends. The diet and physical activity behaviors themselves vary in characteristics and are similar in others. The behavioral science components of these two disciplines face similar problems, and can learn from the advances made by the other, in the areas of measurement, correlates and intervention. By working together, knowledge will be enhanced from uncovering complementary and interactive relationships between diet and physical activity, and in relation to disease risks, that may result in designing more effective and efficient interventions and policies.Since the behavioral sciences are at a disadvantage in comparison to the biological sciences in terms of scientific advances and thereby capturing the popular imagination for solutions to health problems, we must redouble our efforts to enhance funding for behavioral research in regard to diet and physical activity and to make the research advances necessary to prevent the medicalizing of essentially social and behavioral problems. Nutrition and physical activity should most effectively do this together.

Relationships between maternal and child cardiovascular risk factors: ethnic differences and lack of influence of physical activity.

OBJECTIVES: To obtain information about the relationship between cardiovascular and diabetic risk factors of mothers and their children and to determine whether these relationships differ by physical activity or ethnicity. DESIGN: Prospective study. SETTING: The Texas site of the Studies of Child Activity and Nutrition Program. PATIENTS: A 1986 to 1989 triethnic sample (European American, African American, and Hispanic) of 133 mothers and their 6- to 7-year-old children. MAIN OUTCOME MEASURES: Maternal and child fasting insulin levels; total, high-density lipoprotein, and low-density lipoprotein cholesterol levels; triglyceride levels; waist circumference; systolic and diastolic blood pressures; height; weight; and body mass index. Maternal physical activity was assessed by means of a 7-day recall. Child physical activity was assessed by heart rate monitoring. Correlational methods were used to describe the relationships among metabolic risk factors and physical activity; chi2 tests of independence were used to examine the relationships between ethnic groups. RESULTS: Body mass index and waist circumference were significantly (P<.05) associated among Hispanic mothers and their children, but not in other ethnic groups. Insulin, high-density lipoprotein, and low-density lipoprotein levels were significantly associated among African American mothers and their children, but not in other ethnic groups. Maternal and child physical activity were not significantly associated with any of the risk variables or each other. CONCLUSION: The relationships between the risk factors of mothers and children differed by ethnicity, but not by physical activity.

Children's meal patterns have changed over a 21-year period: the Bogalusa Heart Study.

OBJECTIVE: The objective of this study was to analyze children's meal patterns over 2 decades. DESIGN: One 24-hour dietary recall was collected on each child who participated in one of seven cross-sectional surveys. SUBJECTS/SETTING: Dietary intake data were collected on 1,584 10-year-old children (65% white, 35% African American), in Bogalusa, LA, from 1973 to 1994. STATISTICAL ANALYSES: Descriptive statistics and one-way analysis of variance adjusting for gender and ethnicity. RESULTS: From 1973 to 1978, there was a marked increase (P<.0001) in the percentage of children who skipped breakfast, from 8.2% to 29.6%. When school breakfast was introduced in 1981, the proportion of children skipping breakfast declined to 12.5% (P<.01). From 1973-1974 to 1993-1994, the percentage of children eating a school lunch declined from 89.7% (1973-1974) to 78.2% (1993-1994) (P<.001); eating lunch brought from home increased from 5.9% to 11.1% (P<.01); consuming a home dinner decreased from 89.2% to 75.9% (P<.01); eating a dinner prepared outside the home increased from 5.4% to 19.0% (P<.01); consuming a meal at a restaurant increased from 0.3% to 5.4% (P<.0001); consuming snacks decreased (P<.0001); total eating episodes decreased from 6.6 to 5.2 (P<.0001); and eating time span significantly decreased from 12.4 hours to 11.5 hours (P<.0001). Despite these changes in meal patterns, no associations were found between meal patterns and overweight status. CONCLUSIONS: Striking alterations in the meal patterns of children occurred over the 2-decade period. These changes may have implications for the changes in the dietary intakes of children during the same time. However, data from this study do not support an association between meal patterns and children's overweight status. Further research with multiple days of assessment is needed to better understand the complexity of diet as it relates to childhood obesity.

Children's food consumption patterns have changed over two decades (1973-1994): The Bogalusa heart study.

OBJECTIVE: To evaluate types of foods and amounts consumed by 10-year-old children during the period from 1973 to 1994. DESIGN: One 24-hour dietary recall was collected on each child who participated in one of seven separate cross-sectional surveys of 10-year-olds.Subjects/Setting Dietary intake data was collected on 1,584 10-year-old children (65% Euro American, 35% African American), in Bogalusa, LA, from 1973 to 1994 using SAS 8.0 (1999, SAS Institute Inc, Cary, NC). Statistical analyses performed Data were analyzed to calculate descriptive statistics. Pearson's chi(2) test was used for testing equality of percentage of each food group consumed across the seven surveys. Cochran-Armitage trend test and general linear models were used to test for trends, adjusting for total energy intake, ethnicity, and sex. RESULTS: The percentage of children consuming, and the mean gram amount consumed, significantly decreased for fats/oils (P<.0001), desserts (P<.0001), candy (P<.0001), eggs (P<.001), and milk (P<.0001). In contrast, the percentage of children consuming, and the mean gram amount consumed, significantly increased for fruits/fruit juices (P<.01), mixed meats (P<.01), poultry (P<.0001), and cheese (P<.0001). Despite a significant decrease in the percentage of children consuming vegetables (P<.01) and beef (P<.01), the mean gram amount consumed did not change. The percentage of children consuming breads/grains, pork, and snacks did not change, but the mean gram amount of salty snacks (P<.001) significantly increased and the amount of breads/grains (P<.01) and pork (P<.01) significantly decreased. The percentage of children consuming sweetened beverages (P<.01) and condiments (P<.001) decreased while the mean gram amount consumed increased (P<.05) and (P<.0001). The mean gram amount of lunch and dinner consumed increased (P<.0001) but snacks decreased (P<.0001), resulting in no change in total gram amount consumed in a 24-hour period. CONCLUSIONS: Trends in food consumption patterns of children should be considered in the design and implementation of population-based behavior strategies for the promotion of health and prevention of chronic diseases beginning in childhood.

Changes in food group consumption patterns from childhood to young adulthood: the Bogalusa Heart Study.

OBJECTIVE: The objective of this study was to assess changes in food group consumption patterns from childhood to young adulthood. DESIGN: Twenty-four-hour dietary recalls were collected on a longitudinal sample of young adults. SUBJECTS/SETTING: Dietary intake data were collected on 246 young adults (70% European American, 30% African American) aged 19 to 28 years who participated in a previous cross-sectional survey when they were 10-year-olds. STATISTICAL ANALYSES: Descriptive statistics and linear mixed models adjusting for study time (age), sex, and ethnicity. RESULTS: In childhood, consumption of fruits/fruit juice and mixed meats ( P </=.05), desserts, candy, and milk ( P </=.0001) were greater than in young adulthood. Young adulthood consumption was greater for sweetened beverages, poultry and seafood ( P </=.001), salty snacks ( P </=.05), and beef ( P </=.01) compared to childhood. Milk consumption decreased, but the decrease was greater among males ( P </=.0001). Sweetened beverage consumption increased, but the increase was greater for European Americans ( P </=.0001). Candy consumption decreased, but the decrease was greater for African Americans ( P </=.05). CONCLUSIONS: Changes occur in food group consumption patterns from childhood to young adulthood. Overall, there was a decrease in diet quality during this age transition. Understanding eating habits of children early in life is important for planning effective intervention strategies.

Physical activity self-report and accelerometry measures from the Girls health Enrichment Multi-site Studies.

BACKGROUND: Valid and reliable physical activity checklists are needed to assess effectiveness of interventions. This study tested the validity and reliability of the Girls health Enrichment Multi-site Studies (GEMS) Activity Questionnaire. METHODS: Two-hundred and ten African-American girls completed the GEMS Activity Questionnaire (GAQ), a checklist of 28 physical and 7 sedentary activities, including TV viewing, inquiring whether performed on the previous day ("yesterday"), and whether usually performed ("usual"). The girls wore an accelerometer (used as the criterion for validity) for three consecutive days at baseline and after a 12-week pilot intervention. Data from 172 girls at baseline and follow-up were usable for this report. RESULTS: Girls were (mean +/- SD) 8.8 +/- 0.8 years old with a BMI of 22.3 +/- 5.9 kg/m2. The intraclass correlation (ICC) examining reliability for the accelerometer across 3 days at baseline for the combined group was fair (ICC = 0.33, P < 0.21). The test-retest reliability coefficient for the 18-item MET-weighted GAQ yesterday scores for the comparison group of girls was 0.57 (P < 0.001). At baseline and follow-up, nonsignificant correlations were observed between 3-day accelerometer counts/minute and GAQ 18-item usual score for both comparison and intervention groups. A significant correlation was found between change in accelerometer minutes of moderate-to-vigorous activity (MVPA) between 12 noon and 6 PM and change in GAQ physical activities in the comparison girls (R = 0.35, P < 0.01). The TV-usual score was correlated with 3-day accelerometer counts/minute (R = -0.19, P = 0.02) at baseline for the total sample. CONCLUSIONS: Correlations between the GAQ and accelerometer were low, indicating low validity. Although the GAQ may be helpful in describing types of physical activities performed, it needs further development to improve its psychometric properties.

Validity and reliability of a behavior-based food coding system for measuring fruit, 100% fruit juice, vegetable, and sweetened beverage consumption: results from the Girls Health Enrichment Multisite Studies.

BACKGROUND: This paper presents the rationale, reliability, and validity of a behavior-based food coding system for measuring fruit (F), juice (J), vegetable (V), sweetened beverage, and water consumption in children. METHODS: Coding algorithms for FJV, sweetened beverages, and water were developed for use with the Nutrition Data System for Research (NDS-R). Two hundred and ten 8- to 10-year-old African American girls at four field centers completed two 24-h dietary recalls at baseline and at 12 weeks follow-up after a weight gain prevention intervention. Differences in mean baseline consumption of selected food variables and other selected nutrients across the four field centers were analyzed. Intraclass correlation coefficients (ICCs) for reliability across 2 days of food recalls and 12-week test-retest reliability correlations were calculated. For the purposes of this paper, nutrient intake estimates were considered construct validators of food intake, and validity was assessed by correlating the coded food variable servings with nutrient intake. RESULTS: ICCs varied from zero (0.001 for beta carotene equivalents) to moderate (0.44 for sucrose), indicating substantial instability in consumption or reporting. Twelve-week test-retest correlations were slight to moderate (0.09 for lycopene to 0.49 for folate). FJV consumption was negatively related to percent energy from fat (r = -0.28; P = 0.001) and positively related to other nutrients. Sweetened beverage consumption was positively related to energy, sucrose, fructose, and vitamin C consumption. CONCLUSIONS: This behavior-based food coding system demonstrated construct validity among 8- to 10-year-old African American girls and can measure the desired food groups.

Measurement characteristics of diet-related psychosocial questionnaires among African-American parents and their 8- to 10-year-old daughters: results from the Girls' health Enrichment Multi-site Studies.

OBJECTIVE: This paper presents the reliability and validity of several diet-related psychosocial questionnaires. METHODS: At baseline and 12 weeks follow-up, parents/caregivers of one hundred fifty 8- to 10-year-old African-American completed questionnaires on food preparation habits for their daughter, perceived home barriers to healthy eating, and fruit, juice, vegetable (FJV), low-fat and high-fat food availability. Girls completed a sweetened beverage preferences questionnaire and two 24-h dietary recalls to assess intake. Principal components analyses were conducted for two newly designed measures. Internal consistency was calculated and construct validity was assessed between the psychosocial scales and obesity-related dietary variables. RESULTS: Low-fat and high-fat food preparation for daughters, and perceived home barriers to eating low-fat food and FJV subscales were derived from the new questionnaires. Internal consistency reliabilities were moderate (0.58) to substantial (0.80) across all new and existing scales. Test-retest reliabilities were moderate (0.44) to substantial (0.79). Girls' intake of fat as a percentage of energy was positively related to parental high-fat food preparation for daughters (P < 0.01) and negatively related to parental low-fat food preparation practices for daughters (P < 0.05). CONCLUSIONS: Measures of family influences on FJV, fat, and sweetened beverage consumption were internally consistent with moderate to substantial stability. Scales for low-fat and high-fat food preparation practices for daughters achieved construct validity with fat consumption in the hypothesized direction. Family food preparation habits appear to be important targets for future interventions.

Social desirability bias in self-reported dietary, physical activity and weight concerns measures in 8- to 10-year-old African-American girls: results from the Girls Health Enrichment Multisite Studies (GEMS).

BACKGROUND: Social desirability (SocD) may bias children's self-reported health behaviors and attitudes and confound relationships with health outcome measures. METHODS: Ninety-five, 8- to 10-year-old African-American girls completed dietary recalls, a physical activity checklist, psychosocial questionnaires related to diet, and physical activity; and 3 days of physical activity monitoring. Potential SocD construct bias was investigated by comparing designated criterion measures of physical activity, beverage intake, and body mass index (BMI) with respective self-reported measures related to activity, beverage preferences, and body image and weight concerns in cross-sectional regression models. Potential confounding by SocD of associations between self-reported behaviors with BMI was assessed using change-in-coefficient regression analyses. RESULTS: Controlling for age and BMI, overestimates of self-reported activity (P = 0.02), underestimates of sweetened beverage preferences (P = 0.02), and lower ratings of weight concerns and dieting behaviors (P's < 0.05) were related to SocD. Confounding by SocD of associations between self-reported physical activity and energy intake with BMI was found. CONCLUSIONS: In 8- to 10-year-old African-American girls, SocD was found to bias self-reports of diet and physical activity and confound associations between BMI and self-reported physical activity and energy intake. Methods to measure and control SocD bias are needed to reduce potential distortion of relationships between diet and physical activity and health outcomes.

Evaluation of quality control procedures for 24-h dietary recalls: results from the Girls Health Enrichment Multisite Studies.

BACKGROUND: Quality control methods are key components of dietary assessment, but have rarely been evaluated. METHODS: One hundred forty-four 8-10-year-old African-American girls at three field centers completed two 24-h dietary recalls at baseline before a pilot weight gain prevention intervention (one recall collected in-person and one by telephone). The dietary recall data were initially reviewed by the dietary interviewer (Phase 1), then by a local lead nutritionist at the field center (Phase 2), and then by the Nutrition Coordinating Center (NCC) (Phase 3); any differences identified by NCC were reconciled (Phase 4). Bland-Altman and generalizability theory methods were used to assess agreement of consumption for selected food variables and nutrients between phases. RESULTS: Only small differences occurred. Quality control procedures primarily reduced the variances of nutrients rather than caused the means to shift. Most of the variability among phases was due to individual level variability in dietary intake. CONCLUSIONS: Decisions to review dietary recall data beyond local review should be based on the level of precision and accuracy required for the study outcomes and the availability of financial resources.

Psychometric properties of optimism and pessimism: results from the Girls' Health Enrichment Multisite Studies.

UNLABELLED: Background. This study investigated the relationships among optimism, pessimism, physical activity, and dietary behaviors among 8- to 10-year-old African-American girls in the Girls' Health Enrichment Multisite Studies (GEMS). Methods. Ninety-two girls were randomly assigned to a 12-week physical activity and diet intervention or comparison group and completed psychosocial assessments including the Youth Life Orientation Test (YLOT) of optimism and pessimism, physical performance self-concept, physical activity self-efficacy, physical activity outcome expectancies, and physical activity and sedentary preferences. Also, preferences for bottled water and sweetened beverages were assessed. Physical activity and dietary intake were assessed by self-report and parent-report at baseline and follow-up. Also, physical activity was objectively assessed by wearing an accelerometer for 3 days. The psychometric properties of the optimism-pessimism subscales were analyzed. Results. The measures of optimism and pessimism in children were reliable (r = 0.75-0.82). In the multiple regression analyses without the intervention interaction terms, pessimism was positively and significantly related to increases in MET-adjusted usual activity (P = 0.008) and sedentary behaviors (P = 0.0004). Additionally, a negative (P = 0.026) pessimism by intervention interaction term for MET-adjusted usual activity was found such that the intervention group had a lower change in physical activity per unit increase in pessimism compared to the control group. CONCLUSIONS: Among 8- to 10-year-old African-American girls, pessimism was related to increased sedentary behaviors and usual activity. Previous studies have reported relationships between optimism and health-compromising behaviors. This study found that pessimism may positively or negatively influence efforts to increase health-promoting behaviors. Future research should confirm and clarify the meaning of these findings.

Measurement of outcomes, mediators, and moderators in behavioral obesity prevention research.

BACKGROUND: Measurement enables intervention scientists to determine whether their interventions had the intended outcome effects and the expected pathways of effects across mediating variables. Low reliability of measurement (i.e., substantial random error) attenuates the relationships of these measures to other variables, including treatment effects. This attenuation may indicate that interventions were not effective, when in truth they were. There has been little assessment of the quality of measurement in obesity prevention trials. METHOD: A brief review is provided of measurement issues within classical test theory. Seventeen obesity prevention trials were then identified in the literature. The extent to which the reliability and validity of the measures were reported in the articles was assessed. RESULTS: With few exceptions reliability coefficients of measures were not reported in the obesity prevention literature. When they were reported, there was evidence that low reliability attenuated reported intervention outcome relationships. CONCLUSIONS: The quality of measurement is important in intervention science and consequently should be clearly presented in scientific reports of outcomes. Better measures are needed in obesity prevention to provide appropriate tests of state of the art interventions. A brief overview is provided of each of the articles in this special issue on measurement in the Girls health Enrichment Multisite Studies (GEMS).

Measurement characteristics of activity-related psychosocial measures in 8- to 10-year-old African-American girls in the Girls Health Enrichment Multisite Study (GEMS).

BACKGROUND: This paper presents reliability and validity analyses of physical activity-related psychosocial questionnaires completed by 8- to 10-year-old African-American girls at baseline and follow-up assessments of pilot intervention studies in the Girls health Enrichment Multi-site Study (GEMS). METHODS: Two hundred ten girls participated in the GEMS 12-week pilot studies and had their height and weight measured, wore an accelerometer for 3 days and completed a measure of their usual physical activity (PA) at baseline and after the 12-week intervention. Subgroups of girls also completed physical activity-related psychosocial measures at these two time points including: (a) self-concept; (b) self-efficacy; (c) outcome expectancies; and d) preferences. Principal components analysis was conducted on the psychosocial measures obtained at baseline. Cronbach's alpha and test-retest reliability were computed. Convergent validity was assessed by correlating the baseline psychosocial measures with baseline physical activity measures and body mass index (BMI). RESULTS: The following sub-scales were derived: Activity Preference, Positive Expectancies and Negative Expectancies for physical activity. Physical Performance Self-Concept and Self-Efficacy for physical activity were kept as single dimensional scales. Sub-scales, derived from principal components analyses, were Activity Preference, Positive Expectancies, and Negative Expectancies for physical activity. Internal consistency estimates for the various scales were substantial to excellent (0.67-0.85), while test-retest reliability estimates were fair to moderate (0.22-0.56). Correlations between the PA psychosocial sub-scales and measured levels of activity measures showed evidence of convergent validity for the Activity Preference sub-scale, although social desirability may have influenced the significant associations observed. CONCLUSIONS: The Activity Preference was a fairly reliable and valid measure. Further studies are needed to examine the utility of activity-related psychosocial measures in interventions to increase physical activity among preadolescent African-American girls.

Non-curricular approaches for increasing physical activity in youth: a review.

BACKGROUND: To prevent obesity, the physical activity of youth should be increased. Since time for school physical education has declined and curricular interventions have had limited effects, alternative non-curriculum approaches need to be tested. METHODS: A systematic review was conducted to identify research that evaluated the effectiveness of non-curricular interventions on the physical activity of children and adolescents. RESULTS: Results showed that children were active during school break periods and inexpensive interventions further increased activity during these times. Active travel to school offered potential, but its effectiveness was impaired by traffic congestion and parental fears for child safety. Extracurricular, school-based interventions had problems with low attendance, which might be removed if delivered through existing community organizations. Summer day camps offered potential for increasing activity of youth, but research is required to determine how best to convert camp activity into increased post-camp habitual activity. CONCLUSIONS: Physical activity can be increased during school break periods, through existing youth organizations, summer day camps, and possibly through active transportation. Future research should focus on further enhancing the effectiveness of these innovative interventions.

Parental cultural perspectives in relation to weight-related behaviors and concerns of African-American girls.

OBJECTIVE: To determine whether cultural perspectives of parents may influence children's eating and physical activity behaviors and patterns of weight gain. RESEARCH METHODS AND PROCEDURES: African-American girls (ages 8 to 10 years) and their parents (or caregivers) (n = 210) participated at one of four Girls Health Enrichment Multisite Studies Phase 1 Field Centers. At baseline, parents completed questionnaires adapted from the African-American Acculturation Scale (AAAS), the Multiethnic Identity Scale (MEIS), and an original question on Global Cultural Identity. Girls' baseline measures included physical activity assessment by accelerometer, 24-hour dietary recalls, and questionnaires about body image and weight concerns. RESULTS: Principal components analysis indicated the expected AAAS and MEIS factor structures, with moderate to good internal consistency (Cronbach's alpha = 0.61 to 0.82) and some intercorrelation among these measures (r = 0.17 to 0.57). Overall mean (SD) AAAS subscale scores of 4.1 (2.1) and 5.5 (1.8) of a possible 7 and 3.0 (0.9) of a possible 4 on the MEIS indicated, respectively, moderate to high levels of parental African-American cultural orientation and identity with moderate variability. Parental AAAS and MEIS scores were inversely correlated with girls' body image discrepancy and weight concern. One AAAS subscale was positively associated with total energy intake and percentage energy from fat. Overall, however, parental AAAS and MEIS scores were unrelated or inconsistently related to girls' physical activity and diet measures. DISCUSSION: The AAAS and MEIS measures had acceptable psychometric properties, except for weight concern, but did not give a consistent picture of how parental perspectives related to the girls' baseline attitudes and behaviors.
