Development and Implementation of a Food Safety Knowledge Instrument

ABSTRACT:  Little is known about the food safety knowledge of young adults. In addition, few knowledge questionnaires and no comprehensive, criterion-referenced measure that assesses the full range of food safety knowledge could be identified. Without appropriate, valid, and reliable measures and baseline data, it is difficult to develop and implement effective education efforts. Thus, the purpose of this study was to develop a comprehensive, valid, reliable food safety knowledge questionnaire. Questionnaire development followed this process: 1) use of published reports and input from experts in food safety and sanitation (n = 7) to identify key food safety concepts; 2) development of a question bank (n = 101) assessing knowledge of key concepts (i.e., cross contamination prevention'disinfection procedures; safe times/temperatures for cooking/storing foods; groups at greatest risk for foodborne disease; foods that increase risk of foodborne disease; and foodborne disease pathogens); 3) refinement of initial questions by experts; 4) questionnaire pretest with young adults (n = 180) and refinement; 5) questionnaire pilot test (n = 126) and refinement; 6) final expert review and refinement; and 7) conversion into an online survey. Young adults (n = 4343, mean age 19.9 ± 1.7SD years) from 21 universities and colleges across the country completed the questionnaire. Item analysis was used to determine the overall quality of the test and identify improvements needed. Livingston's coefficient of reliability for criterion-referenced tests was 0.92. The questionnaire met or exceeded generally recognized standards of reliability and validity. This questionnaire could be useful in baseline assessment of food safety knowledge and measurement of knowledge gained after an educational intervention in adults.     

Using the theory of planned behaviour to develop a questionnaire on teachers' beliefs about teaching cancer education

This study explored methodological challenges related to eliciting and assessing teachers’ beliefs about teaching cancer education. We aimed to develop reliable belief scales, a methodological innovation in the context of the theory of planned behaviour (TPB), as single belief items are typically used as predictors for direct measures. The expectancy-value product proved useful for identifying categories of teachers’ beliefs about cancer education. Six reliable belief scales emerged, for example, control beliefs about external emotional and non-emotional inhibitors and internal facilitators. We also discuss methodological issues related to eliciting beliefs and forming reliable belief scales.     

The social conflict inventory (SCI): A measure of beliefs about classroom peer conflicts

Abstract

This study describes the development of the Social Conflict Inventory (SCI), a self‐report teacher belief scale for assessing beliefs about young children's classroom peer conflicts. Three phases were involved in the construction of the SCI: item development, initial testing with one sample (n = 218), and follow‐up field test with a second sample (n = 395) that also addressed the convergent and concurrent validity of the instrument. Reliability and factor analyses conducted during the initial field test resulted in a reduction to 20 items (Cronbach’ s α = .87) with three subscales: General Orientation to Peer Conflict (α = .81), Cessation (α = .84), and Facilitation (α = .65). Similar patterns of factor loadings and reliabilities resulted from analyses of the follow‐up field test data. Overall, the SCI proved to be a reliable instrument for assessing the beliefs concerning the role of classroom conflicts in children's development and for differentiating among groups of teachers. Further use of the SCI in conjunction with other measures of teacher beliefs will contribute to a better understanding of its concurrent validity. Finally, the potential for its use in future studies to clarify the relationship between beliefs and actual classroom practices and as an instrument for assessing the effectiveness of specific classroom management training programs is discussed.     

Self-efficacy as a predictor of commitment to the teaching profession: A meta-analysis

This meta-analysis examined research on the effects of preservice and inservice teachers' self-efficacy beliefs on commitment to the teaching profession. Unlike previous studies on self-efficacy and commitment, this review systematically examines the effects found within the literature and highlights important theoretical and methodological issues. A total of 33 qualified studies were included in the final analysis, including 16,122 preservice and inservice teachers. Findings suggest that preservice and inservice teachers' self-efficacy beliefs influence their commitment to the teaching profession (ES = +0.32). However, these effects vary based upon the conceptual accuracy of the self-efficacy measure and the origin of data. Conceptually accurate self-efficacy measures resulted in significantly higher effect sizes. Additionally, the specificity of questionnaire items and conceptual accuracy of the self-efficacy measure positively predicted the relationships between self-efficacy beliefs and commitment to teaching. Implications for the measurement of self-efficacy and interpretation of preservice and inservice teacher self-efficacy beliefs are presented.

Teachers’, school staff’s and parents’ efficacy beliefs as determinants of attitudes toward school

Self- and collective efficacy beliefs were examined as correlates of attitudes toward school of teachers, school staff, and parents. 726 teachers, 387 staff members, and 1994 parents from 18 junior high schools in Milan and Rome, Italy, were administered questionnaires assessing self-efficacy beliefs, perceptions about colleagues’ bahavior, collective efficacy beliefs, affective commitment and job satisfaction of teachers and school staff and parents satisfaction with school. Path analyses corroborated a conceptual model in which self- and collective efficacy beliefs represent, respectively, the distal and proximal determinants of affective commitment and job satisfaction for teachers and staff and of satisfaction with school for parents. Perceptions that teachers, staff and parents hold about the behavior of their colleagues largely mediated the links between self- and collective efficacy beliefs. collective efficacy beliefs, in turn, largely mediated the influence that self-efficacy beliefs and perceptions of school constituencies’ behaviors exert on attitudes toward school of teachers, staff and parents.     

An Assessment of the HIV Prevention Needs of Young Minority Women

This study tested the reliability of nine scales assessing psychosocial mediators of HIV-risk and protective behaviors of young minority women in New York City. Sixty-nine age-eligible women were approached during clinical sessions, 90% (n = 62) agreed to participate, and 83% (n = 57) completed a web-based survey. With one exception, scale measures were reliable. The exception was the scale assessing frequency of sexual communication with partners. This scale did not demonstrate adequate interitem reliability for Black women. Findings provide program planners with a reliable set of measures that may be useful for preintervention needs assessments of young minority women at-risk of acquiring HIV.     

Changes in the relation of self-efficacy beliefs and behaviors across development

Many social science theories that examine the connection between beliefs and behaviors assume that belief constructs will predict behaviors similarly across development. Converging research implies that this assumption may not be tenable across all ages or all belief constructs. Thus, to test this implication, the relation between behavior and beliefs about the self was examined in 2 independent data sets with 2 different constructs: aggression and achievement. The respondents were 6-18 years of age and predominately Caucasian. Results using quasi-simplex structural equation models suggest that self-beliefs become more strongly related to behavior as children grow older independent of the reliability of the measures used. Possible limitations in the use of self-report methodology with young children are discussed.     

LIST FORMATS IMPROVE MEDICATION INSTRUCTIONS FOR OLDER ADULTS

We conducted a survey to compare a group of older adults’ and a group of younger adults’ beliefs regarding their own and each other's memory abilities. We also asked both age groups to identify items they believed older adults remember well. The survey was returned by 185 older (ages 60‐92) and 184 younger (ages 17‐39) participants. Of the 30 items we generated older adults reported that they would remember 23 better than younger adults would and 7 worse than younger adults would, and younger adults reported that they would remember 12 of the items better and 18 of them worse than older adults. Both age groups also generated many items that they believed older adults remember better than younger adults do. Finally, respondents generated items that they believed adults in their own age group had to remember routinely that adults in the other age group did not. The two groups agreed that older adults would spend more time and have more difficulty learning lines for presentation to an audience than would younger adults. Most of the older adults reported that their memories had changed; most of the younger adults reported that their memories had not changed. The belief that although older adults’ memory is worse than young adults’ they still remember some things better than the young is viewed as a realistic assessment, and implications for future research are discussed.     

Scientific epistemic beliefs, conceptions of learning science and self-efficacy of learning science among high school students

This study examined the relationships among Taiwanese high school students’ scientific epistemic beliefs, conceptions of learning science, and self-efficacy of learning science. The questionnaire responses gathered from 377 high school students in Taiwan were utilized to elicit such relationships. The analysis of the structural equation model revealed that students’ absolutist scientific epistemic beliefs led to lower-level conceptions of learning science (i.e. learning science as memorizing, preparing for tests, calculating, and practicing) while sophisticated scientific epistemic beliefs might trigger higher-level conceptions of learning science (i.e. learning science as increase of knowledge, applying, and attaining understanding). The students’ lower-level conceptions of learning science were also found to negatively associate with their self-efficacy of learning science, while the higher-level conceptions of learning science fostered students’ self-efficacy. However, this study found that students who viewed scientific knowledge as uncertain (advanced epistemic belief) tended to possess lower self-efficacy toward learning science.     

The Multivariate Dimensionality of Personal Control and Future Time Perspective Beliefs in Achievement and Self-Regulation

We examined the relations between college students' control beliefs and future time perspective (FTP) and their academic achievement and studying using canonical correlation. We identified two statistically significant canonical correlations. One associated primarily competency belief, as reflected by self-efficacy, and FTP connectedness with grades. The other associated primarily contingency beliefs, as reflected by locus of control and causal attributions, and FTP connectedness and valence with studying. Results support a distinction between competency and contingency in personal control beliefs and suggest that these have somewhat different motivational consequences. Results also indicate that future time perspective beliefs play a role in motivating achievement and studying.     

Reading and writing self-efficacy of incarcerated adults

This paper is the first to examine the Reading and Writing Self-Efficacy Scale among incarcerated adults. The aim was to examine whether performance of reading and spelling tests (Reading Speed, Nonsense Words and Spelling) explained individual differences in the participants' efficacy beliefs in reading and writing. Six hundred subjects rated their efficacy beliefs in reading and writing, and 92 of them were also sampled for a reading and spelling test. Factor analysis yielded a two-factor solution dividing the reading items and writing items into separate factors and hierarchical regression analysis revealed that education level and test performance accounted for 36.9% and 34.9% of the statistical variance in reading self-efficacy and writing self-efficacy, respectively. The results suggest that assessment of self-efficacy in reading and writing should be included in a screening procedure of reading and spelling difficulties.     

Heterogeneity and Change in the Patterning of Adolescents' Perceptions of the Legitimacy of Parental Authority: A Latent Transition Model

Changes in the patterning of adolescents' beliefs about the legitimate domains of parental authority were modeled in 2,611 Chilean adolescents, 11–16 years old. Transitions in adolescents' belief patterns were studied over 3 years. Latent transition analysis (LTA) revealed 3 distinct patterns of beliefs— parent control , shared control , and personal control— that differed in the extent to which adolescents believed that parents had legitimate authority over personal, prudential, and multidomain issues. Younger adolescents with fewer problem behaviors, higher self-efficacy, and more parental rules were more likely to espouse the parent control belief pattern. Adolescents' patterning of beliefs was relatively stable over time. Older adolescents with more problem behaviors and fewer parental rules were most likely to move away from the parental control status.     

Assessing Early Childhood Teachers' Beliefs About Emotions: Content, Contexts, and Implications for Practice

This study aimed to develop a measure of early childhood practitioners' beliefs about emotions and to use this measure to examine the structure and correlates of these beliefs. A 40-item emotion beliefs measure was administered to 279 American practitioners. Internal consistency for each of 10 emotion belief areas was weak to moderate. In revising the measure, emotion belief areas with the lowest internal consistency were deleted and items were added to the 6 remaining areas to strengthen their reliability. The resulting 23-item revised measure had internal consistencies of .41 to .62 for each of 6 emotion belief areas. Participants' emotion beliefs were related to their level of education and background in early childhood education. A 4-factor solution provided the best fit to the data, explaining 40% of the variance in the U.S. teachers' emotion beliefs. This factor structure was similar to that of the conceptually derived belief scales. Cultural patterns were examined by comparing beliefs of Korean and American teachers of 4-6-year-olds, using t-tests and factor analyses. Although the structure of emotion beliefs was similar, differences appeared in the level of agreement with many items, reflecting culturally specific expectations a b u t young children's emotional vulnerability and about the nature of emotional bonds and emotion socialization in early childhood programs.     

Exploring Self-Efficacy among Entry-Level and Advanced BSW Students

This study compared a sample of entry-level and advanced BSW students, who completed pretest and posttest self-efficacy measures, to assess their level of confidence in performing social work tasks after 15 weeks of instruction. By the end of the semester, only advanced students made significant gains in self-efficacy beliefs, and they showed a significantly higher self-efficacy belief than entry-level students. Results suggest that increased mastery experiences, as found in the advanced social work curriculum, may help students develop confidence in their ability to practice as professional social workers.     

Assessing Teachers' Beliefs about Their Science Teaching Context

The primary purpose of this study was to develop and apply a method for assessing teachers' context beliefs about their science teaching environment. Interviews with 130 purposefully selected teachers resulted in 28 categories of environmental factors and/or people who were perceived to influence science teaching. These categories were used to develop items for the Context Beliefs about Teaching Science instrument and provided evidence for content validity. Construct validity was partially confirmed through factor analysis that resulted in 26 items and two subscales on the final instrument. Using Ford's Motivation Systems Theory and Bandura's Theory of Collective Efficacy, additional evidence for construct validity was found in the modest correlation of context beliefs with outcome expectancy beliefs and the low correlation with science teaching self‐efficacy beliefs. The instrument was tested using 262 teachers participating in long‐term science professional development programs. These teachers possessed fairly positive context beliefs and, according to Ford's theory, should be capable of effective functioning in the classroom. It was concluded that the assessment of context beliefs would complement current science teacher self‐efficacy measures, thereby allowing researchers to develop profiles of science teachers' personal agency belief patterns. It could also be used to determine the factors which predict particular personal agency belief patterns, and assess teachers' perceptions of the strengths and weaknesses of school science programs, and could be used in planning and monitoring professional development experiences for science teachers. © 2000 John Wiley & Sons, Inc.

Behavioral Competence among Mothers of Infants in the First Year: The Mediational Role of Maternal Self-Efficacy

This study tests the idea that mothers' self-efficacy beliefs mediate the effects on parenting behavior of variables such as depression, perceptions of infant temperamental difficulty, and social-marital supports. Subjects were 48 clinically depressed and 38 nondepressed mothers observed in interaction with their 3-13-month-old infants (M = 7.35 months). As predicted, maternal self-efficacy beliefs related significantly to maternal behavioral competence independent of the effects of other variables. When the effects of self-efficacy were controlled, parenting competence no longer related significantly to social-marital supports or maternal depression. In addition, maternal self-efficacy correlated significantly with perceptions of infant difficulty after controlling for family demographic variables. These results suggest that maternal self-efficacy mediates relations between maternal competence and other psychosocial variables and may play a crucial role in determining parenting behavior and infant psychosocial risk.     

Growing up with adversity: From juvenile justice involvement to criminal persistence and psychosocial problems in young adulthood

Several studies have been carried out to investigate the effect of child maltreatment on juvenile justice involvement and future criminal life. However, little is known about the impact of other forms of adversity, beyond abuse and neglect, on juvenile delinquency and criminal persistence. The effect of early adversity on psychosocial problems is underexplored, particularly in juvenile delinquents. This study, using the Childhood Adverse Experiences (ACE) questionnaire, a tool accessing the exposure to different types of abuse, neglect and serious household dysfunction, explored the role of each adverse experience on juvenile justice involvement, persistence in crime and psychosocial problems during young adulthood. A Portuguese sample of 75 young adults with official records of juvenile delinquency in 2010/2011, and 240 young adults from a community sample completed ACE questionnaire and measures of psychosocial adjustment. Seven out of ten adverse experiences were significantly more prevalent in young adults with juvenile justice involvement than in the community sample, after matching the main demographic variables. The strongest predictor of juvenile justice involvement and criminal persistence during early adulthood was sexual abuse. Dimensions of child/adolescent emotional maltreatment and a mental illness in the household predicted a set of psychosocial problems in young adulthood. This study indicates that early adversity is significantly related to juvenile justice involvement, criminal persistence and psychosocial problems. This study also suggests that each experience has a different role in this process. There is an urgent need to screen, prevent and stop serious adversity. Future scientific directions and recommendations for policies are provided.     

High school students’ scientific epistemological beliefs,self-efficacy in learning physics and attitudes toward physics: a structural equation model

Background: There are some theoretical evidences that explain the relationships between core beliefs (i.e., epistemological beliefs) and peripheral beliefs (self-efficacy in learning) in the literature. The close relationships of such type of beliefs with attitudes are also discussed by some researchers. Constructing a model that investigates these relationships by considering theoretical and empirical evidences can empower researchers to discuss these relationships more comprehensively.

Purpose: The purpose of this study is to explore the relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.

Sample: A total of 632 high school students participated in this study; however, 269 female and 229 male (a total of 498) high school students’ data were used.

Design and methods: Three distinct instruments that measure scientific epistemological beliefs, self-efficacy in learning physics and attitudes toward physics were combined into a unique questionnaire form and it was distributed to high school students. To explore the relationships among these variables, structural equation modeling was used.

Results: The results showed that scientific epistemological belief dimensions uncovered by the nature of knowing (source and justification) significantly and positively related to both self-efficacy in learning physics and attitudes toward other important physics dimensions. Additionally, self-efficacy in learning physics significantly and positively predicted attitudes toward multiple physics dimensions (importance, comprehension and requirement). However, epistemological belief dimensions related to the nature of knowledge (certainty and development) did not have significant impact on self-efficacy in learning physics or attitudes toward physics.

Conclusions: This study concludes that there are positive and significant relationships among Turkish high school students’ scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics.     

Examining Determinants of Efficacy Judgments as Factors in Health Promotion Message Design

Self-efficacy is a predictor of behavioral performance across a range of health domains, and research suggests that media messages can effectively boost efficacy; however, much is unknown regarding determinants of self-efficacy, and the message features with the greatest potential to alter efficacy perceptions. The authors of this article examined skill and motivation as determinants of efficacy and tested their effectiveness as message variables. Study 1 identified health behaviors that young adults felt unable to perform, as well as behavior barriers and facilitators. Study 2 isolated one behavior, exercise, and tested messages targeting either skill or motivation as a determinant of self-efficacy to exercise. Matched messages engendered greater general self-efficacy than unmatched messages, though no differences emerged on self-efficacy magnitude and strength measures. Follow-up data indicated that participants low in motivation exercised more than those low in skill regardless of message condition. Implications of these findings for health promotion efforts are discussed.
