The purpose of this study was to test a motivational model of the coach-athlete relationship, based on self-determination theory and on the hierarchical model of intrinsic and extrinsic motivation. The sample comprised of 608 athletes (ages of 12-17 years) completed the following measures: interest in athlete's input, praise for autonomous behavior, perceived autonomy, intrinsic motivation, and the intention to be physically active. Structural equation modeling results demonstrated that interest in athletes' input and praise for autonomous behavior predicted perceived autonomy, and perceived autonomy positively predicted intrinsic motivation. Finally, intrinsic motivation predicted the intention to be physically active in the future. The results are discussed in relation to the importance of the climate of autonomy support created by the coach on intrinsic motivation and adherence to sport by adolescent athletes. Further, the results provide information related to the possible objectives of future interventions for the education of coaches, with the goal of providing them with tools and strategies to favor the development of intrinsic motivation among their athletes. In conclusion, the climate of autonomy support created by the coach can predict the autonomy perceived by the athletes which predicts the intrinsic motivation experienced by the athletes, and therefore, their adherence to athletic practice.

Given the high prevalence of overweight and low levels of physical activity among children, a better understanding of physical activity behaviour is an important step in intervention planning. This study, based on the theory of planned behaviour, was conducted among 313 fifth graders and their parents. Children completed a computer-based questionnaire to evaluate theoretical constructs and behaviour. Additional information was obtained from parents by means of a questionnaire. Correlates of children's physical activity were intention and self-identity. Determinants of intention were self-efficacy, self-identity, and attitude. Parental variables were mediated through cognitions. Among girls, practicing sedentary activities was an additional negative determinant of intention. Key beliefs of boys and girls were related to time management and difficulties associated with physical activity. For girls, social identification as an active girl was another important belief related to positive intention. This study provides theory-based information for the development of more effective interventions aimed at promoting physical activity among children.
The aim of this study was to establish motivational profiles for doing physical activity according to the variables from the theory of planned action in a sample of 698 students aged 14 to 16. The instruments used were the Questionnaire of Behavioral Regulation in Sport (BRQ-R) and the Questionnaire of the Theory of Planned Behavior (TCP). Cluster analysis revealed two motivational profiles: a “self-determined ”profile with high scores in intrinsic motivation and low scores in extrinsic motivation and amotivation, and a “non self- determined ”profile with low scores in intrinsic motivation and high scores in extrinsic motivation and amotivation. Positive significant differences in attitudes, norms, and intent to control were found for the self-determined profile related to “non self-determined ”profile.
A “self-determined ”profile was found with higher scores for the four types of intrinsic motivations (general, knowledge, stimulation and achievement) and identified regulation than for introjected and external regulation.
A “non self-determined ”profile was found with higher scores for external, introjected regulation and amotivation than for the four types of intrinsic motivation (general, knowledge, stimulation and achievement).
In the context of the “non self-determined profile ”we could encourage programs that adapt to these needs in such a way that they contribute to increasing the rates of doing physical activity in the population.

Both habit strength and action planning have been found to moderate the intention-exercise behaviour relationship, but no research exists that has investigated how habit strength and action planning simultaneously influence this relationship. The present study was designed to explore this issue in a prospective sample of undergraduate students (N = 415): action planning, habit strength, intention, attitudes, subjective norms and perceived behavioural control were assessed at baseline and exercise behaviour was assessed 2 weeks later. Both habit strength and action planning moderated the intention-exercise relationship, with stronger relationship at higher levels of planning or habit strength. Decomposing a significant action planning × habit strength × intention interaction showed that the strength of the intention-exercise relationship progressed linearly through levels of action planning and habit strength. These novel results show that action planning strengthens the intention-habit strength interaction in the exercise domain: exercise interventions should therefore focus on simultaneously bolstering action planning and habit strength.

This study explored the extent to which trait aggression is associated with suicidal behavior in a nationwide school-based sample of adolescents.
A nationwide sample of 14,537 high school students in urban areas of China was recruited. Information concerning suicide ideation, plans, attempts, trait aggression and other risk factors was collected by a self-reported questionnaire. Multivariate regression analyses were employed to predict suicidal behavior.
Approximately 18.5% of students reported suicide ideation, 8.7% reported suicide plans, and 4.1% reported attempts during the past one year. Hostility and trait anger had a significant positive association with suicidal ideation. Hostility and physical aggression were positively related to suicide plans. Hostility had a positive correlation with suicide attempts, while trait anger was inversely associated with suicide attempts.
This study suggests that hostility, physical aggression and trait anger may be able to be used to predict suicidal behavior among adolescents. Suicide prevention programs should target at attenuating the severity of hostility, anger and physical aggression. But teachers and parents should also give close attention to students with low trait anger.
Greek-affiliated college students have been found to drink more heavily and frequently than other students. With female student drinking on the rise over the past decade, sorority women may be at particular risk for heavy consumption patterns. The current study is the first to apply the Theory of Planned Behavior (TPB) to examine drinking patterns among a sorority-only sample. Two-hundred and forty-seven sorority members completed questionnaires measuring TPB variables of attitudes, norms, perceived behavioral control, and intentions, with drinking behaviors measured one month later. Latent structural equation modeling examined the pathways of the TPB model. Intentions to drink mediated the relationship between attitudes and norms on drinking behavior. Subjective norms predicted intentions to drink more than attitudes or perceived behavioral control. Perceived behavioral control did not predict intentions but did predict drinking behaviors. Interpretation and suggestions from these findings are discussed.

To test self-regulation concepts in relation to dietary intake and physical activity patterns in adolescence, which we predicted to be influenced by components of a self-control model.
A survey was conducted with a multiethnic sample of 9th grade public school students in a metropolitan area (N = 539). Confirmatory analysis tested the measurement structure of self-control. Structural equation modeling tested the association of self-control constructs with measures of fruit and vegetable intake, saturated-fat intake, physical activity, and sedentary behavior.
Confirmatory analysis of 14 indicators of self-control showed best fit for a two-factor structure, with latent constructs of good self-control (planfulness) and poor self-control (impulsiveness). Good self-control was related to more fruit and vegetable intake, more participation in sports, and less sedentary behavior. Poor self-control was related to more saturated-fat intake and less vigorous exercise. These effects were independent of gender, ethnicity, and parental education, which themselves had relations to diet and exercise measures. Multiple-group modeling indicated that effects of self-control were comparable across gender and ethnicity subgroups.
Self-control concepts are relevant for patterns of dietary intake and physical activity among adolescents. Attention to self-control processes may be warranted for prevention programs to improve health behaviors in childhood and adolescence.

Objective. This study was conducted to identify some factors (beliefs and norms) which are related to fast food consumption among high school students in Isfahan, Iran. We used the framework of the theory planned behavior (TPB) to predict this behavior. Subjects & Methods. Cross-sectional data were available from high school students (n = 521) who were recruited by cluster randomized sampling. All of the students completed a questionnaire assessing variables of standard TPB model including attitude, subjective norms, perceived behavior control (PBC), and the additional variables past behavior, actual behavior control (ABC). Results. The TPB variables explained 25.7% of the variance in intentions with positive attitude as the strongest (β = 0.31, P < 0.001) and subjective norms as the weakest (β = 0.29, P < 0.001) determinant. Concurrently, intentions accounted for 6% of the variance for fast food consumption. Past behavior and ABC accounted for an additional amount of 20.4% of the variance in fast food consumption. Conclusion. Overall, the present study suggests that the TPB model is useful in predicting related beliefs and norms to the fast food consumption among adolescents. Subjective norms in TPB model and past behavior in TPB model with additional variables (past behavior and actual behavior control) were the most powerful predictors of fast food consumption. Therefore, TPB model may be a useful framework for planning intervention programs to reduce fast food consumption by students.
Intention is a key determinant of action. However, there is a gap between intention and behavioural performance that remains to be explained. Therefore, the aim of this study was to identify moderators of the intention-behaviour and perceived behavioural control (PBC)- behaviour relationships for leisure-time physical activity.
This was tested in reference to Ajzen's Theory of Planned Behaviour. A sample of 300 volunteers, 192 women and 108 men, aged 18 to 55, participated in the study. At baseline, the participants completed a self-administrated psychosocial questionnaire assessing Ajzen's theory variables (i.e., intention and perceived behavioural control). The behavioural measure was obtained by mail three months later.
Multiple hierarchical regression analyses indicated that age and annual income moderated the intention-behaviour and PBC-behaviour relationships. However, in the final model predicting behaviour (R2 = .46), only the interaction term of PBC by annual income (β = .24, p = 0.0003) significantly contributed to the prediction of behaviour along with intention (β = .49, p = 0.0009) and past behaviour (β = .44, p < 0.0001).
Physical activity promotion programs would benefit not only from focusing on increasing the intention of low intenders, but also from targeting factors that moderate the perceived behavioural control-behaviour relationships.
Although the Internet has become an important avenue for disseminating health information, theory-driven strategies for aiding individuals in changing or managing health behaviors are lacking. The eHealth Behavior Management Model combines the Transtheoretical Model, the behavioral intent aspect of the Theory of Planned Behavior, and persuasive communication to assist individuals in negotiating the Web toward stage-specific information. It is here — at the point of stage-specific information — that behavioral intent in moving toward more active stages of change occurs.
The eHealth Behavior Management Model is applied in three demonstration projects that focus on behavior management issues: parent-child nutrition education among participants in the U.S. Department of Agriculture Special Supplemental Nutrition Program for Women, Infants and Children; asthma management among university staff and students; and human immunodeficiency virus prevention among South African women. Preliminary results have found the eHealth Behavior Management Model to be promising as a model for Internet-based behavior change programming. Further application and evaluation among other behavior and disease management issues are needed.
Little information describes how adolescents change their smoking behavior. This study investigated the role of gender in the relationship of motivation and cognitive variables with adolescent smoking self-change efforts. Self-report and semi-structured interview data from a prospective study of smoking self-change efforts were examined among 98 adolescent smokers ages 14–18 (55% female). Social disapproval motives and short-term consequence reasons for quitting, quit self-efficacy and intentions to quit were modeled in relation to prospective self-quit attempts assessed at a 6-month follow-up, separately by gender. Hypothesized mediating relationships were not supported although gender differences were noted. Social influence motives related to intention to quit and prospective self-quit attempts among girls. For boys, intention to quit predicted making a self-quit attempt. Findings emphasize the importance of examining adolescent models separately by gender and contribute to understanding of mechanisms involved in adolescent smoking change efforts.

The aim of this study was to examine the physical activity of children with and without asthma in Greece, the factors affecting their intention to exercise, and the influence of gender.
The study involved 50 children with asthma and 50 children without asthma, aged 9–14-years old. We used the leisure time exercise questionnaire to assess the frequency and intensity of exercise. The planned behavior scale examined seven factors affecting physical activity: attitude, intention, self-identity, attitude strength, social role model, information, and knowledge.
Asthmatic children did not differ significantly in mild, moderate, and overall level of physical activity from children without asthma but they participated less in intense and systematic exercise. The two asthmatic groups did not differ in any of the planned behavior factors. Significant differences between genders occurred with respect to self-identity and social role model. Boys appeared to exercise more regularly and intensely compared to girls.
Asthmatic children did not systematically participate in physical activity, preferring mostly mild and moderate intensity activities. Children with and without asthma had comparable positive attitudes and intentions toward exercise.

The aim of this study was to develop a scale for assessing and predicting adolescents’ physical activity behavior in Spain and Luxembourg using the Theory of Planned Behavior as a framework. The sample was comprised of 613 Spanish (boys = 309, girls = 304; M age =15.28, SD =1.127) and 752 Luxembourgish adolescents (boys = 343, girls = 409; M age = 14.92, SD = 1.198), selected from students of two secondary schools in both countries, with a similar socio-economic status. The initial 43-items were all scored on a 4-point response format using the structured alternative format and translated into Spanish, French and German. In order to ensure the accuracy of the translation, standardized parallel back-translation techniques were employed. Following two pilot tests and subsequent revisions, a second order exploratory factor analysis with oblimin direct rotation was used for factor extraction. Internal consistency and test-retest reliabilities were also tested. The 4-week test-retest correlations confirmed the items’ time stability. The same five factors were obtained, explaining 63.76% and 63.64% of the total variance in both samples. Internal consistency for the five factors ranged from α = 0.759 to α = 0. 949 in the Spanish sample and from α = 0.735 to α = 0.952 in the Luxembourgish sample. For both samples, inter-factor correlations were all reported significant and positive, except for Factor 5 where they were significant but negative. The high internal consistency of the subscales, the reported item test-retest reliabilities and the identical factor structure confirm the adequacy of the elaborated questionnaire for assessing the TPB-based constructs when used with a population of adolescents in Spain and Luxembourg. The results give some indication that they may have value in measuring the hypothesized TPB constructs for PA behavior in a cross-cultural context.
When using the structured alternative format, weak internal consistency was obtained. Rephrasing the items and scoring items on a Likert-type scale enhanced greatly the subscales reliability.
Identical factorial structure was extracted for both culturally different samples.
The obtained factors, namely perceived physical competence, parents’ physical activity, perceived resources support, attitude toward physical activity and perceived parental support were hypothesized as for the original TPB constructs.

Background: Regular physical activity is ranked as a leading health indicator. Despite the extensive benefits of physical activity, elder people are much less active than desired. Using Theory of Planned Behavior (TPB) and the self-efficacy construct, this study examined the prediction of physical activity intention and behavior in a sample of elderly male resident of a nursing home.
Methods: In a cross-sectional study of the residents of Kahrizak Nursing Home in Tehran, Iran, elderly men who were 60 years or older, capable of independent living, mobility, and verbal communication were asked to complete measures of the TPB, self-efficacy and physical activity behavior.
Results: A hierarchical step-wise multiple regression analysis indicated that affective/instrumental attitude, subjective norm, and perceived behavioral control (PBC) explained 32.8% of the variance in physical activity intention, and self-efficacy provided an additional 2.7%. In a reverse step regression, the TPB variables explained an additional 12.2% of physical activity intention. In a multiple regression analysis on physical activity behavior, affective/instrumental attitude, subjective norm, perceived behavioral control (PBC) and intention explained 15.7% of the variance in physical activity behavior while self-efficacy contributed an additional 5.6%. In the reverse step regression, TPB predictors contributed an additional 3.0% in explaining the variance in physical activity behavior.
Conclusion: The results indicate that in addition to the TPB, self-efficacy may also play an important role in the prediction of behavior, and should be included in the design of physical activity programs for elderly men of nursing home residents.

Regular physical activity has positive effects on physical, mental and social aspects of individual and community health. Considering the prevalence of noncommunicable diseases such as primary hypertension, osteoporosis and cardiovascular diseases for which sedentary lifestyle is a responsible factor, health policy makers have planned to encourage people to do more physical activities. Development of beneficial health habits during childhood and early adolescence are very important because the behaviors, which start at adolescence tend to continue into adulthood, too. This study aimed to determine the effect of educational intervention on physical activity-related knowledge, attitude and behavior of the first grade students in male high schools of Bavanat in 2010.
Materials and Methods:
In this prospective experimental study, after selecting two qualified schools from five high schools, all students of one school (two classes including 42 individuals) were randomly assigned to the experimental group and all the students of another high school (two classes including 43 individuals) were randomly assigned to the control group. The data gathering tool was a 4-section questionnaire which included demographic questions, knowledge- and attitude-related questions and the questionnaire of physical activity performance. The first three sections of the questionnaire were the researcher-designed and validated by face and content validity. Test-retest and internal consistency (Cronbach's Alpha) methods were used to determine the reliability of knowledge questionnaire and attitude questionnaire, respectively. For the measurement of physical activity behavior, a self-reporting questionnaire (valid and reliable Garcia scale) was used in this study. After conducting the pretest, the educational intervention was done for the experimental group. Post-tests were conducted immediately and 1 month after intervention. The collected data were analyzed using SPSS18 statistical software (independent t-test, paired t-test, chi-square, Mann-Whitney test and repeated measures ANOVA). The participants voluntarily and consciously participated in this study.
The findings indicated no significant differences between the groups in terms of mean scores of knowledge (P = 0.934), attitude (P = 0.155) and behavior (P = 0.387) before the intervention. There was a significant difference between mean scores of knowledge in the immediate follow-up (P< 0.001) and 1 month after intervention follow-up (P < 0.001), and also between mean scores of attitude immediately (P < 0.001) and 1 month after intervention (P = 0.01) follow-ups in the experimental group compared with the control one. Mean scores of physical activity 1 month after the intervention in both experimental and control groups significantly increased (P < 0.001, P = 0.01, respectively), but the mean scores of physical activity between two groups were not significantly different (P = 0.390).
Discussion and Conclusion:
The results indicated the effectiveness of educational intervention, consequently increased knowledge and improved attitude of students, in the experimental group compared with the control one in terms of physical activities; thus, physical activity behavior of intervention group increased. Although the mean scores of physical activity in the control group significantly increased, other studies should be done which can control and consider confounding variables.

(a) To examine different methods of assessing pregnancy intention; (b) to identify psychosocial differences between those who indicate pregnancy intentions and those who do not; and (c) to examine the relationship between pregnancy intentions and subsequent pregnancy at 6-month follow-up in nonpregnant (at baseline), sexually experienced adolescent females.
Longitudinal cohort study of 354 sexually experienced female adolescents attending either a STD clinic or HMO adolescent medicine clinic in northern California. Student’s t-tests and regressions examined psychosocial differences between females who reported “any” and “no” pregnancy intentions. ANOVAs examined differences among different combinations of pregnancy plans/likelihood. Chi-square analyses assessed associations between baseline pregnancy intentions and subsequent pregnancy.
Adolescents’ reports of their pregnancy plans and their assessments of pregnancy likelihood differed from one another (χ2 = 50.39, df = 1, p < .001). Pregnancy attitudes and baseline contraceptive use differentiated those with inconsistent pregnancy intentions (Not Planning, but Likely) from those with clear pregnancy intentions (Planning and Likely, and Not Planning and Not Likely) (Pregnancy Attitudes: F [2,338] = 68.96, p < .0001; Contraceptive Use: F [2,308] = 14.87, p < .0001). Suspected pregnancies and positive pregnancy test results were associated with baseline pregnancy intentions (Suspected: χ2 = 19.08, df = 2, p < .01; Positive Results: χ2 = 8.84, df = 2, p = .015).
To reduce adolescent childbearing we must assess pregnancy intentions in multiple ways. Information/education might benefit those female adolescents with inconsistent reports of pregnancy intentions.

To identify psychosocial differences between sexually experienced male adolescents who indicate intentions to get someone pregnant and those who do not.
Cross-sectional study of 101 sexually experienced adolescent males recruited from an STD clinic in northern California. Student’s t-tests and regressions examined psychosocial differences between males who reported any intention versus no intention to get someone pregnant in the next six months. ANOVAs examined differences among different combinations of pregnancy plans/likelihood.
Adolescents’ reports of their plans for getting someone pregnant differed from their assessments of the likelihood that they would do so (χ2 = 24.33, df = 1, p < .0001). Attitudes toward pregnancy and participants’ mothers’ educational attainment differentiated those with clear pregnancy intentions (Planning, and Likely) from those with clear intentions to avoid pregnancy (Not Planning & Not Likely)
To reduce the rates of adolescent childbearing, males’ pregnancy intentions must be assessed and asked about in multiple ways.

Much is known about predictors of risky sexual behaviors in young adults. Little is known; however, about the contribution of temperament and how temperament interacts with context to influence sexual risk intentions and actual behaviors. Since intentions are closely linked to behavior, knowing how temperament influences these decisions is important in planning interventions. The purpose of this quasiexperimental study was to examine the effect of gender, temperament, and context on sexual risk intentions and behaviors among college students (N = 145). Although individual components of temperament were associated with sexual risk intentions, temperament did not predict sexual risk intentions in a safer or risky context or actual behaviors. There were also no differences by gender. In this study, temperament did not interact with context to influence sexual risk intentions or behaviors. According to these results, interventions promoting safer sexual behaviors may not have to be tailored to individuals with different temperament styles.
Bicycle use entails high safety and health risks especially for adolescents. Most safety education programs aimed at adolescents focus on accident statistics and risk perceptions. This paper proposes the investigation of the social-cognitive correlates of risky cycling behaviors of adolescents prior to developing safety education programs.
Secondary school students aged 13 to 18 years (n = 1446) filled out questionnaires regarding bicycle behavior, risky intentions, accident experience, and social-cognitive determinants as suggested by the theory of planned behavior.
Regression analysis revealed that the proximal variables (i.e., self-efficacy, attitudes towards drunk driving, personal norm regarding safekeeping of self and others, and compared risk) were able to predict 17% of the variance of risky behavior and 23% of the variance of risky intentions. The full model explained respectively 29% and 37% of the variance in risky behavior and risky intentions. Adolescents with positive attitudes towards risky behavior and low sense of responsibility report risky behavior, even when having been (close to) an accident.
Adolescents realize whether they are risk takers or not. This implies that the focus of education programs should not be on risk perceptions, but on decreasing positive attitudes towards alcohol in traffic and increasing sense of responsibility instead. Cognitions regarding near accidents should be studied, the role of safe cycling self-efficacy is unclear.
Objective To explain, through mediation analyses, the mechanisms by which ATHENA (Athletes Targeting Healthy Exercise and Nutrition Alternatives), a primary prevention and health promotion intervention designed to deter unhealthy body shaping behaviors among female high school athletes, produced immediate changes in intentions for unhealthy weight loss and steroid/creatine use, and to examine the link to long-term follow-up intentions and behaviors. Methods In a randomized trial of 1668 athletes, intervention participants completed coach-led peer-facilitated sessions during their sport season. Participants provided pre-test, immediate post-test, and 9-month follow-up assessments. Results ATHENA decreased intentions for steroid/creatine use and intentions for unhealthy weight loss behaviors at post-test. These effects were most strongly mediated by social norms and self-efficacy for healthy eating. Low post-test intentions were maintained 9 months later and predicted subsequent behavior. Conclusions ATHENA successfully modified mediators that in turn related to athletic-enhancing substance use and unhealthy weight loss practices. Mediation analyses aid in the understanding of health promotion interventions and inform program development.

This article describes the integrative model of behavioral prediction (IM), the latest formulation of a reasoned action approach. The IM attempts to identify a limited set of variables that can account for a considerable proportion of the variance in any given behavior. More specifically, consistent with the original theory of reasoned action, the IM assumes that intentions are the immediate antecedents of behavior, but in addition, the IM recognizes that environmental factors and skills and abilities can moderate the intention-behavior relationship. Similar to the theory of planned behavior, the IM also assumes that intentions are a function of attitudes, perceived normative pressure and self-efficacy, but it views perceived normative pressure as a function of descriptive as well as of injunctive (i.e., subjective) norms. After describing the theory and addressing some of the criticisms directed at a reasoned action approach, the paper illustrates how the theory can be applied to understanding and changing health related behaviors.

This study compared autonomous self-regulation and negative self-evaluative emotions as predictors of smoking behavior change in college student smokers (N=303) in a smoking cessation intervention study. Although the two constructs were moderately correlated, latent growth curve modeling revealed that only autonomous regulation, but not negative self-evaluative emotions, was negatively related to the number of days smoked. Results suggest that the two variables tap different aspects of motivation to change smoking behaviors, and that autonomous regulation predicts smoking behavior change better than negative self-evaluative emotions.

This paper examined the extent to which assignment to a pay-for-performance (P4P) experimental condition impacted therapists’ intentions to deliver high quality treatment and the extent to which therapists’ intentions could be explained by the theory of planned behavior. Data were collected from 95 therapists who agreed to participate in a P4P experiment related to their implementation of an evidence-based treatment (EBT) for adolescents with substance use problems. Relative to those in the control condition, therapists in the P4P condition reported significantly greater intentions to achieve monthly competence (B = 1.41, p < .001) and deliver a targeted threshold level of treatment to clients (B = 1.31, p < .001). Additionally, therapists’ intentions could be partially explained by the theory of planned behavior. Meta-analyses have found intentions to be one of the best predictors of behavior, thus these findings provide initial support for using P4P approaches as a method of increasing the quality of substance use treatment.

Youths eat fewer fruits and vegetables than recommended. Effective methods are needed to increase and maintain their fruit and vegetable consumption. Goal setting has been an effective behavior change procedure among adults, but has had limited effectiveness among youths. Implementation intentions are specific plans to facilitate goal attainment. Redefining goal setting to include implementation intentions may be an effective way to increase effectiveness. Video games offer a controlled venue for conducting behavioral research and testing hypotheses to identify mechanisms of effect.
This report describes the protocol that guided the design and evaluation of Squire’s Quest! II, a video game aimed to increase child fruit and vegetable consumption.
Squire’s Quest! II is a 10-episode videogame promoting fruit and vegetable consumption to 4th and 5th grade children (approximately 9-11 year old youths). A four group randomized design (n=400 parent/child dyads) was used to systematically test the effect of two types of implementation intentions (action, coping) on fruit and vegetable goal attainment and consumption of 4th and 5th graders. Data collection occurred at baseline, immediately post game-play, and 3 months later. Child was the unit of assignment. Three dietary recalls were collected at each data collection period by trained interviewers using the Nutrient Data System for Research (NDSR 2009). Psychosocial and process data were also collected.
To our knowledge, this is the first research to explore the effect of implementation intentions on child fruit and vegetable goal attainment and consumption.
This intervention will contribute valuable information regarding whether implementation intentions are effective with elementary age children.

The purpose of this research was to investigate how university students' nutrition beliefs influence their health behavioral intention. This study used an online survey engine (Qulatrics.com) to collect data from college students. Out of 253 questionnaires collected, 251 questionnaires (99.2%) were used for the statistical analysis. Confirmatory Factor Analysis (CFA) revealed that six dimensions, "Nutrition Confidence," "Susceptibility," "Severity," "Barrier," "Benefit," "Behavioral Intention to Eat Healthy Food," and "Behavioral Intention to do Physical Activity," had construct validity; Cronbach's alpha coefficient and composite reliabilities were tested for item reliability. The results validate that objective nutrition knowledge was a good predictor of college students' nutrition confidence. The results also clearly showed that two direct measures were significant predictors of behavioral intentions as hypothesized. Perceived benefit of eating healthy food and perceived barrier for eat healthy food to had significant effects on Behavioral Intentions and was a valid measurement to use to determine Behavioral Intentions. These findings can enhance the extant literature on the universal applicability of the model and serve as useful references for further investigations of the validity of the model within other health care or foodservice settings and for other health behavioral categories.
