Late adolescent risk-taking: effects of perceived benefits and perceived risks on behavioral intentions and behavioral change.

To assess the predictive utility of perceived benefits and risks of risk-taking behaviors (RTBs) on behavioral intentions and behavioral change, data were collected from 187 male and female late adolescent college students (ages 17-20). Perceived benefits, perceived risks, behavioral intentions, and involvement for 18 RTBs were assessed at T1 and T2 (3 months later). Factor analyses were performed on T1 involvement data, and six RTB factors emerged: Alcohol RTBs, Illegal Drug RTBs, Stereotypic Male RTBs, Social RTBs, Sex RTBs, and Imprudent RTBs. Regression analyses indicated that perceived benefits accounted for significant variance in behavioral intentions for each of the six factors and Overall RTB; perceived risks accounted for significant variance in behavioral intentions for five of the factors. Similar regression analyses indicated that perceived benefits accounted for significant variance in behavior change (over a 3 month period) for each of the six factors and the Overall RTB score, whereas perceived risks accounted for significant variance for only one factor (Illegal Drug RTBs). The result suggest that, among late adolescents, perceived benefits are better determinants of behavior change for RTBs than are perceived risks. Both perceived benefits and perceived risks, however, are important determinants of behavioral intentions. These findings support previous work identifying adolescents as "sensation seekers". Interventions should address perceived benefits of RTB, rather than relying solely on promoting knowledge of the risks. Assessment of adolescent RTB should continue to use multi-item measures to obtain a broad picture of the variety of behaviors commonly endorsed by adolescents.

The development of health knowledge in low-income Mexican-American children.

Children growing up in poverty are at risk for various health problems. For low-income, Mexican-American children, these risks include obesity, diabetes, and accidental injuries, 3 conditions that can largely be prevented by healthy life-styles. Despite the potential for prevention through education leading to health-promoting behaviors, very little is known about the development of health knowledge in this population. The present study examined low-income, Mexican-American children's understanding of the relation between health behavior and health status in 3 areas: nutrition, hygiene, and safety. 79 children (41 boys, 38 girls) ages 4 to 8 years participated. Children's knowledge was assessed in a structured play situation conducted in a laboratory setting. Results revealed that children knew the least about the relation between food consumption and their health, and knew the most about beneficial and harmful practices in the areas of safety and hygiene. Age and gender differences were also significant, with girls and older children more likely to provide elaborate and complex rationales for their responses. Implications of the findings for understanding the role of cognitive development and experience in the development of health knowledge are considered.

Mexican-American mothers' socialization strategies: effects of education, acculturation, and health locus of control.

The present study examined maternal education, acculturation, and health locus of control beliefs in relation to parenting strategies that promote the internalization of healthy eating habits in Mexican-American children. Eighty low-income Mexican-American mothers and their 4- to 8-year-old children participated in the study. Mother-child interactions during dinner were observed, and mothers were interviewed about the socialization strategies they used to influence their children's food consumption. Results indicated that mothers with more external health locus of control beliefs were less likely to use socialization techniques associated with internalization. Acculturation was negatively related to the use of internalization techniques, with less traditional mothers using more directive strategies. Education did not predict maternal behavior after controlling for health locus of control beliefs.

Adolescent risk-taking: an analysis of problem behaviors in problem children.

In this study adolescent risk-taking is explored from several theoretical positions: Jessor's problem-behavior perspective, risk-taking as normal and adaptive, adolescent egocentrism, and a decision-making perspective. Adolescents (ages 11-17) referred to mental health clinics (N = 80) completed a risk involvement and perception questionnaire, the Jesness Personality Inventory, and a measure of adolescent egocentrism. For purposes of concurrent validity, a diagnosis was completed by the subject's clinic therapist. As predicted, both Benefit and Risk Perception were significantly correlated with Involvement (in opposite directions), supportive of a decision-making perspective. A configuration of social maladjustment personality correlates in conjunction with a diagnosis of Conduct Disorder showed a strong, positive correlation with Involvement, supporting a problem-behavior perspective. Egocentrism measures were not significantly related to Risk Involvement or Risk and Benefit Perceptions. Adolescent risk-taking is argued to be a multidimensional phenomenon involving personality correlates and cognitive aspects of decision-making.

Cuidando El Corazon--a weight-reduction intervention for Mexican Americans.

Cuidando El Corazon (CEC; Taking Care of Your Heart) was designed to assess the effectiveness of a culturally adapted weight-reduction and exercise program for achieving long-term weight loss in Mexican Americans. CEC used a family-oriented approach to achieve lifestyle change in behavior. Participants were assigned to 1) a booklet-only comparison group that received a manual including behavior change, nutrition, and exercise information and traditional recipes modified in fat content; 2) an individual group that received the same manual and attended year-long classes; or 3) a family group that received a manual and attended classes that emphasized techniques for making changes in the family's eating and exercising habits. The family and individual groups had significantly greater weight losses than the information-only group. Weight loss was greatest in the family-involvement group and least in the information-only comparison group.

Self-concept and perceptions of attractiveness and body size among Mexican-American mothers and daughters.

The socialization of physical attractiveness stereotypes and its relationship to self-concept among parent/child dyads has not been previously examined. This study examined the relationship between mothers' and daughters' judgements of body size and the impact of size on subjects' judgements of attractiveness. Mexican-American mothers and their 7-12-year-old daughters completed attractiveness ratings of five figures of girls varying in body size and indicated which of these figures were closest to the perceived and ideal sizes of the daughter. One-half of the mothers were obese and had participated in a behavioral weight loss program, while the other half served as normal weight controls. Self-concept measures were also completed by all subjects. Daughters tended to prefer a thinner figure than did mothers. The control mothers indicated almost no preference for body size, with nearly uniform rankings for obese, normal and thin figures. The daughters ranked their own ideal figures as thinner than their perceived figures, but mothers' rankings of their daughters' ideal and actual sizes were congruent. Daughter's overall self-concept was predicted by age, their own size and their mother's size. Control but not intervention mothers' self-concept was negatively correlated with their size.

Maternal socialization of children's eating habits: strategies used by obese Mexican-American mothers.

Mexican-Americans are more likely to be obese than the general population, yet little research has been conducted on the socialization of eating habits in Mexican-American children. 38 obese mothers enrolled in a weight-loss program and their 4-8-year-old children were observed during mealtime and the mothers interviewed about their socialization practices. Mothers relied primarily on nondirective verbal control strategies during the observation. Child compliance was more likely to follow a maternal serving or command than a nondirective behavior. Mothers encouraged sons to eat more than did mothers of girls. Child age was negatively correlated with mother's use of commands, reasoning, threats, and bribes, and positively correlated with maternal nondirectives, servings, and child compliance. Mothers with more years of formal education served healthier foods and were more likely to report using reasoning strategies, prohibiting consumption of unhealthy food, monitoring child food consumption away from home, and allowing child input into the eating situation than were less educated mothers.

Way finding and cognitive mapping in large-scale environments: a test of a developmental model.

First, fourth, and seventh graders (7, 10, and 13 years of age, respectively) were given a series of tasks to assess their spatial competency in and their cognitive mapping of their school campus. Measures of way-finding, landmark, route, and configurational knowledge were obtained and analyzed to (1) assess way-finding skills in the same environment as that in which their cognitive representations were inferred and assessed; (2) determine the validity of the hierarchical model of cognitive mapping development proposed by Siegel and White by examining individual children's performance patterns as well as between-group performance; and (3) investigate the relationship between grade level and familiarity within an environment where familiarity within subsets of the environment varied by grade. Subjects were asked to create and walk three novel and efficient routes, to select photographs of scenes belonging to the three routes, to correctly order and metrically relate those scenes, and to make bearing and distance estimates from four sighting locations to six targets within the environment. Results indicated that all children were extremely competent way finders. Guttman scale analysis revealed that 93% of all children exhibited performance patterns predicted by the proposed model. Further support of the model was found in grade level differences on cognitive mapping measures. Reversals in the developmental trend were found, however, on some portions of the route and configuration measures, and were significantly related to degree of familiarity within the environment.

Family versus individually oriented intervention for weight loss in Mexican American women.

Mexican Americans are more likely to be obese than non-Hispanic whites, yet little research has been conducted on the treatment of obesity in Mexican Americans. The purpose of this study was to compare a family-based intervention with a traditional program oriented to the individual for achieving weight loss by obese Mexican American women. A total of 168 obese women were randomly assigned to one of three groups. Group 1 served as a comparison group and received only printed materials on nutrition, exercise, and behavioral principles for weight loss. Subjects in the individual group (group 2) received the same printed information, but they also attended classes led by bilingual registered dietitians. Subjects in the family group (group 3) received materials and attended classes that emphasized a family-oriented approach to making changes in eating habits and exercise behavior. Spouses and children attended classes with subjects in this group. Results revealed a significant linear trend in both body mass index and weight reduction across the groups, with losses greatest in the family group, followed by the individual group, and least in the comparison group. Both the individual and the family groups lost significantly more weight than the comparison group, although the difference between these two groups was not statistically significant. The results suggest that a culturally and linguistically appropriate program can achieve significant weight reduction among Mexican Americans. More research should be conducted on the effects of family and other types of social support on weight loss by Mexican Americans.
