A Goal Setting Intervention Positively Impacts Adolescents’ Dietary Behaviors and Physical Activity Self-Efficacy

The efficacy of a youth development intervention on improving eating and physical activity(PA) self-efficacy, goal attainment scaling, goal effort, and behaviors was examined in a repeated measures, quasi-experimental field trial. Ethnically diverse students (n=64) from a low-income middle school participated in the 10-session intervention driven by the Social Cognitive Theory with a Goal Setting Theory emphasis. Participants, 13-14 years old, made significant changes in dietary behaviors (P=0.03) and PA self-efficacy (P=0.02) after receiving the intervention. Self-efficacy did not mediate dietary behavior change but did mediate the small changes made in PA. Goal effort was not a mediator of behavior change. After the intervention, more participants rated themselves as making one lasting improvement in eating (

Assessing factorial and convergent validity and reliability of a food behaviour checklist for Spanish-speaking participants in US Department of Agriculture nutrition education programmes

Objective—To assess convergent validity, factorial validity, test–retest reliability and internal consistency of a diet quality food behaviour checklist (FBC) for low-literate, low-income Spanish speakers. Design—Participants (n 90) completed three dietary recalls, the Spanish-language version of the US Department of Agriculture (USDA) Household Food Security Survey Module (HFSSM) and the Spanish-language FBC. Factor structure was examined using principal component analysis. Spearman correlation coefficients between FBC item responses and nutrient intakes from 24 h recalls were used to estimate convergent validity. Correlation coefficients were also calculated between FBC item responses at two time points in another group of participants (n 71) to examine test–retest reliability. Cronbach's α coefficient was determined for items within each sub-scale. Setting—Non-profit community agencies serving low-income clients, migrant farm worker camps and low-income housing sites in four California counties. Subjects—Spanish-speaking women (n 161) who met income eligibility for the SNAP-Ed (Supplemental Nutrition Assistance Program–Education). Results—Factor analysis resulted in six sub-scales. Responses to nineteen food behaviour items were significantly correlated with hypothesized 24 h recall data (with a maximum correlation of 0·44 for drinking milk and calcium) or the USDA HFSSM (0·42 with the food security item). Coefficients for test–retest reliability ranged from 0·35 to 0·79. Cronbach's α ranged from 0·49 for the diet quality sub-scale to 0·80 for the fruit and vegetable sub-scale. Conclusions—The twenty-two-item FBC and instruction guide will be used to evaluate USDA community nutrition education interventions with low-literate Spanish speakers. This research contributes to the body of knowledge about this at-risk population in California

Misreporting of Dietary Intake Affects Estimated Nutrient Intakes in Low-Income Spanish-Speaking Women

Misreporting of dietary intake affects the validity of data collected and conclusions drawn in studies exploring diet and health outcomes. One consequence of misreporting is biological implausibility. Little is known regarding how accounting for biological implausibility of reported intake affects nutrient intake estimates in Hispanics, a rapidly growing demographic in the United States. Our study explores the effect of accounting for plausibility on nutrient intake estimates in a sample of Mexican-American women in northern California in 2008. Nutrient intakes are compared with Dietary Reference Intake recommendations, and intakes of Mexican-American women in a national survey are presented as a reference. Eighty-two women provided three 24-hour recalls. Reported energy intakes were classified as biologically plausible or implausible using the reported energy intakes to total energy expenditure cutoff of 1.24, with low-active physical activity levels used to estimate total energy expenditure. Differences in the means of nutrient intakes between implausible (n=36) and plausible (n=46) reporters of energy intake were examined by bivariate linear regression. Estimated energy, protein, cholesterol, dietary fiber, and vitamin E intakes were significantly higher in plausible reporters than implausible. There was a significant difference between the proportions of plausible vs implausible reporters meeting recommendations for several nutrients, with a larger proportion of plausible reporters meeting recommendations. Further research related to misreporting in Hispanic populations is warranted to explore the causes and effects of misreporting in studies measuring dietary intake, as well as actions to be taken to prevent or account for this issue

Assessing Face Validity of a Physical Activity Questionnaire for Spanish-Speaking Women in California

To create a culturally appropriate assessment, the study reported here developed and evaluated the face validity of a visually enhanced Spanish-language physical activity questionnaire. A professional translated the English version of the International Physical Activity Questionnaire (IPAQ), and an expert panel subsequently reviewed it. Photos of individuals engaged in physical activity behaviors were added. Cognitive interviews were completed with low-income Spanish-speaking women in California (n=20). Questionnaire text was modified and then reviewed by translation experts (n=7). With a high readability score of 98, the questionnaire demonstrates adequate face validity and is ready for further validation

Acculturation, physical activity and television viewing in Hispanic women: findings from the 2005 California Women's Health Survey

Objective—To assess the relationship of acculturation with physical activity and sedentary behaviours among Hispanic women in California. Design—Data from the 2005 California Women's Health Survey (CWHS) – a cross-sectional telephonic survey of health indicators and health-related behaviours and attitudes – were used. Setting—Using a random-digit dialling process, data were collected monthly from January to December 2005. Subjects—A total of 1298 women aged ≥18 years in California who self-identified as Hispanic. Results—Of the participants included in the analysis, 49% were adherent to physical activity recommendations (with 150 min of weekly activity signifying adherence). There was no significant association between language acculturation and moderate or vigorous physical activity after controlling for potential confounders such as smoking, age and employment status. There was also no association between duration of residence in the USA and moderate or vigorous physical activity. Language acculturation was positively associated with television (TV) viewing, with highly acculturated women reporting more hours of TV viewing compared with women with an intermediate acculturation score (P=0.0001), and those with an intermediate score reporting more hours of TV viewing compared with those with a low score (P=0.003). This relationship persisted after inclusion of smoking, employment status, age and education in the model. Conclusions—Higher levels of language acculturation may be associated with increased sedentary behaviours because of the influence of US culture on those women who have assimilated to the culture. Acculturation is an important factor to be taken into account when designing health education interventions for the Hispanic female population

Guided Goal Setting: A Feasible Obesity Prevention Behavior Change Strategy for Low-Income Parents with Young Children

To reduce the risk of pediatric obesity, behaviorally-focused parental education is needed. This study examined the feasibility of guided goal setting in a pediatric obesity prevention intervention for low-income parents of young children. Parents from Head Start participated in a six-week nutrition, activity, and parenting intervention that included guided goal setting (N = 47). At each session, data were collected on goal selection, effort, and attainment. Pre- and postintervention data were collected on nutrition, activity, and child feeding behaviors (n = 24). A subset of parents completed in-depth interviews (n = 20). Parents reported a high level of goal effort (88%) and achievement (79%) and a preference for goal personalization and a list of goals from which to choose. In general, parents did not find the goal contract or weekly tracking as motivating as goal personalization. Pre- and postintervention assessment showed significant changes in the dietary energy density (p = .008) and vegetable behavior (p = .04) subscales with a marginal change in the snacking subscale (p = .08). Guided goal setting was a feasible behavioral strategy for the parents in this study since parents engaged in the process and demonstrated changes in serving more vegetables and fewer energy-dense foods

A Goal Setting Intervention Positively Impacts Adolescents’ Dietary Behaviors and Physical Activity Self-Efficacy

After the intervention, more participants rated themselves as making one lasting improvement in eating (

Using Qualitative Methods to Improve Questionnaires for Spanish Speakers: Assessing Face Validity of a Food Behavior Checklist

Development of outcome measures relevant to health nutrition behaviors requires a rigorous process of testing and revision. Whereas researchers often report performance of quantitative data collection to assess questionnaire validity and reliability, qualitative testing procedures are often overlooked. This report outlines a procedure for assessing face validity of a Spanish-language dietary assessment tool. Reviewing the literature produced no rigorously validated Spanish-language food behavior assessment tools for the US Department of Agriculture’s food assistance and education programs. In response to this need, this study evaluated the face validity of a Spanish-language food behavior checklist adapted from a 16-item English version of a food behavior checklist shown to be valid and reliable for limited-resource English speakers. The English version was translated using rigorous methods involving initial translation by one party and creation of five possible versions. Photos were modified based on client input and new photos were taken as necessary. A sample of low-income, Spanish-speaking women completed cognitive interviews (n=20). Spanish translation experts (n=7) fluent in both languages and familiar with both cultures made minor modifications but essentially approved client preferences. The resulting checklist generated a readability score of 93, indicating low reading difficulty. The Spanish-language checklist has adequate face validity in the target population and is ready for further validation using convergent measures. At the conclusion of testing, this instrument may be used to evaluate nutrition education interventions in California. These qualitative procedures provide a framework for designing evaluation tools for low-literate audiences participating in the US Department of Agriculture food assistance and education programs

Evidence to Support the Use of the Retrospective Pretest method to Measure Dietary and Physical Activity Behavior and Self-Efficacy in Adolescents

This study compared the retrospective pretest-posttest method to the traditional prospective pretest-posttest method assessing adolescents’ dietary and physical activity, self-efficacy and behaviors. Participants were 7th and 8th grade students at a rural K-8th grade elementary school in Northern California (n=188). All participants completed an evaluation instrument (traditional pretest), followed by a 9-lesson dietary and physical activity intervention. Upon completion of the intervention, participants completed a second and identical evaluation instrument which served as a traditional posttest. The following day, participants completed another evaluation tool, this time formatted as a retrospective pretest. Analysis included sample t tests comparing the means of each method. Participants (n = 154) with a mean age of 13 ± .7 years old were included in the analyses (52% female). Paired sample t tests reported non-significant differences between the two methods for dietary behavior and dietary self-efficacy, yet significant differences were found for physical activity behavior (p < .05) and physical activity self-efficacy (p < .01). We conclude that the retrospective pretest-posttest method was as good a measure of dietary self-efficacy and behavior as the traditional prospective pretest-posttest method and may be better at attenuating response-shift bias when assessing physical activity self-efficacy and behavior
