Development of Food Safety Psychosocial Questionnaires for Young Adults

Journal of Food Science Education 03/2007; 6(2):30 - 37.

ABSTRACT   Food mishandling is thought to be more acute among young adults; yet little is known about why they may engage in risky food handling behaviors. The purpose of this study was to create valid, reliable instruments for assessing key food safety psychosocial measures. Development of the measures began by examining published studies and behavior change theories to identify the psychosocial factors associated with personal health choices and 3 psychosocial factors were identified: beliefs, locus of control, and self-efficacy. Development of items for the belief questionnaire began by identifying the belief constructs that could provide insight into how food safety behavior change programs should be framed to evoke improved behaviors and drafting items. The locus of control questionnaire was modeled after the Health Locus of Control Questionnaire. Self-efficacy questionnaire development included defining self-efficacy, identifying environmental contexts affecting self-efficacy, and constructing an item pool. The questionnaires were pretested with young adults (n= 180) and refined. A pilot test (n= 77) was conducted to further refine the beliefs and self-efficacy questionnaires. Finally, young adults (n= 4343, mean age 19.9 ± 1.7 SD y) from 21 universities and colleges across the country completed the questionnaires. Analysis of their responses revealed that these questionnaires met or exceeded standards indicative of high-quality psychosocial food safety measures. These questionnaires should be useful in generating baseline data from adults as well as establishing the value of these measures in assessing the effectiveness of food safety interventions.

    ABSTRACT: Foodborne diseases represent a widespread and growing public health problem worldwide. The global occurrence of these diseases is difficult to calculate, but high levels of mortality have been reported. The aim of this study was to investigate the knowledge of food handler's and consumers concerning foodborne diseases, personal hygiene, risk groups, temperature control, cross-contamination and cleaning in the municipality of Mirandela, northeastern Portugal. Data were collected through a self-administered questionnaire from a convenience sample of 400 adults aged 18 years or older. The majority of respondents had a level of knowledge regarded as sufficient about the control of temperature in food. In addition, participants also demonstrated to be well informed on measures of hygiene. Most of the participants correctly answered questions about knowledge related to cross-contamination.This survey showed that there is a gap in the consumers' knowledge on foodborne microbiological and parasitological agents. The respondents with a lower level of public education presented significantly higher knowledge than participants with an academic degree. In conclusion, in order to reduce occurrence, it is necessary to continue improving the knowledge on foodborne diseases, not only for the final consumer but also throughout of the whole production and distribution chain, as well as in restaurants.

    ABSTRACT: form only given. The new conjugated polymer poly(tetraphenylquinodimethans) (PTPhQ) with degenerate ground state has been obtained in linear (presumably 10) and not-work (presumably 2D) modification by the method of oxidative condensation of diphenylmethane or its chlorine derivatives in the presence of Lewis acids. The PTPhQ has all properties characteristic for conjugated polymers. The neutral form of 1D PTPhQ is soluble and films can be obtained from solutions. Transformation of PTPhQ from neutral to doped form is accompanied by changes in optical spectra and increasing of its conductivity. The doping of PTPhQ by Lewis acids is accompanied by appearance and growth of ESR signal. For example when the 1D PTPhQ is doped by SbCl/sub 5/ the ESR signal with g - value about 2, /spl Delta/ H = 7,2/sup 5/ - 7,9 Gauss and spin concentration more than 10/sup +22/ spins/mo] is observed. The very wide line ( > 5000 Gauss) without fine structure in spectra ESR is also observed.

    ABSTRACT: This study examined engineering student's self reported intention and behaviour in practising safety at workshops and laboratories by using the Theory of Planned Behaviour (TPB) with extension of Safety Knowledge as research framework. Eighty eight (n=88) participants from three engineering departments of a completed a survey questionnaire measuring their responses to five constructs of the framework. The multiple regressions results show that subjective norms were the most significant predictors of behavioural intention towards practising safety followed by perceived behavioural control and safety attitude. The second block of multiple regressions found that safety behaviour can be significantly explained by using the constructs of safety knowledge and behavioural intention. Overall, this study has shown that three explanatory variables in the TPB can explain behavioural intention of practising safety with 52% of variance and safety knowledge as an extension construct of the TPB model with behavioural intention can explain the young adult's safety behaviour in the laboratories and workshops with the variance of 40%.
