Étude sur les déterminants psychosociaux de la vaccination contre le virus A(H1N1) auprès des parents d’enfants qui fréquentent des services de garde éducatifs de Montréal

Introduction En juin 2009, l’Organisation Mondiale de la Santé (OMS) a déclaré l’état de pandémie pour le nouveau virus influenza A(H1N1). Malgré les recommandations des autorités de santé publique, lors de la mise en place de la campagne de vaccination de masse au Québec contre ce virus pandémique, certains groupes de la population ont été plus enclins à être vaccinés que d’autres groupes. Ceci souligne l’importance des déterminants psychosociaux du comportement humain, sujet qui a donné cadre à notre étude. Objectifs Le but de cette étude a été de documenter les attitudes, les connaissances et les influences sociales des parents dont les enfants fréquentent des services de garde éducatifs (SGE) vis-à-vis la vaccination contre la pandémie ainsi que la couverture vaccinale. Méthodologie Un questionnaire auto-administré et anonyme basé sur la théorie des comportements interpersonnels de Triandis a été distribué aux parents d’enfants âgés de 0-59 mois de neuf centres de la petite enfance sur l’île de Montréal. Résultats Le taux de réponse de l’enquête a été de 32,0% (N=185). Le taux de vaccination des enfants s’est retrouvé à 83,4%; ceci représente une couverture plus élevée que la moyenne régionale et nationale. Toutefois, à une question sur l’intention des parents face à une autre pandémie, seuls 46% des parents feraient vacciner leur enfant. Les facteurs les plus significatifs associés à la vaccination de leur enfant ont été les croyances personnelles positives, de bonnes habitudes vaccinales et l’influence des média, tous mesurés par plusieurs indicateurs (RC respectifs de 7,7, 3,1 et 4,2, p<0,05). Conclusion Pour la grippe A(H1N1), plusieurs facteurs contextuels ont joué en faveur des taux de vaccination acceptables chez les enfants. Toutefois, la mise en place d’une campagne de la vaccination par les instances gouvernementales et de santé publique en utilisant divers média pourraient contribuer à un taux de vaccination encore plus élevé en cas d’épidémie ou de pandémie.

Utilisation des connaissances issues de la recherche en éducation Validation d’un questionnaire et proposition d’un modèle

La recherche sur l’utilisation des connaissances issues de la recherche (CIR) est en pleine expansion. Plusieurs études ont montré que l’utilisation des CIR contribue à améliorer la réussite scolaire des élèves. Toutefois, il semble que les enseignants les utilisent très peu. Pour améliorer cette utilisation, il est nécessaire de développer un modèle explicatif de l’utilisation des connaissances issues de la recherche. Ce modèle permet de rendre compte des mécanismes menant à l’utilisation des connaissances issues de la recherche en milieu de pratique. Il permet également de mettre en évidence les facteurs les plus influents et l’agencement de ces différents facteurs dans le but de favoriser une meilleure utilisation des connaissances issues de la recherche. Ce dernier aspect constitue l’objectif principal de cette thèse pour le domaine spécifique de l’éducation. Pour ce faire, un questionnaire sur l’utilisation des connaissances issues de la recherche (QUC) est validé et un modèle est proposé. Le premier article de la thèse examine la fiabilité, la validité et la structure factorielle du QUC avec un échantillon francophone et anglophone d’un milieu défavorisé. Le QUC, composé de 43 items, mesure six dimensions, soit : l’utilisation des connaissances issues de la recherche, le contexte organisationnel, la stratégie de soutien, l’opinion des utilisateurs et leur expertise ainsi que la fréquence d’accès aux sources des connaissances issues de la recherche. Au total, 2270 enseignants ont complété le questionnaire. Les résultats des différentes analyses montrent que le QUC doit être réduit à 20 items regroupés en cinq facteurs : l’utilisation des connaissances issues de la recherche, l’opinion des utilisateurs, la stratégie de soutien, l’expertise des utilisateurs et les facteurs organisationnels. Le second article de cette thèse examine quel modèle permet de mieux expliquer l’utilisation des CIR. Pour ce faire, deux modèles sont testés avec le même échantillon que dans le premier article, soit un modèle de liens directs et un modèle avec médiation. Pour le premier modèle, un lien direct entre l’utilisation des connaissances issues de la recherche et les facteurs qui favorisent cette utilisation est postulé : l’expertise, l’opinion, la stratégie de soutien et le facteur organisationnel auront des liens directs avec l’utilisation des connaissances issues de la recherche. Le second modèle (modèle avec médiation) se base quant à lui sur les théories de l’action raisonnée et du comportement planifié et postule que le lien entre les facteurs et l’utilisation n’est pas direct; certains facteurs ont des effets directs et d’autres des effets indirects. Concrètement, ce second modèle postule que l’expertise et l’opinion agissent comme médiateurs entre, d’une part, les deux variables indépendantes (le facteur organisationnel et la stratégie de soutien), et, d’autre part, la variable dépendante (l’utilisation des connaissances issues de la recherche). Les résultats des analyses montrent que le modèle avec médiation permet de mieux comprendre l’utilisation des connaissances issues de la recherche. Cette étude a permis de valider un questionnaire sur l’utilisation des connaissances issues de la recherche et aboutit à la proposition d’un modèle qui permet d’expliquer l’utilisation des connaissances issues de la recherche spécialement conçu pour le domaine de l’éducation. Elle fournit des outils (un questionnaire validé et un modèle) qui permettent de mieux cerner le paradigme de l’utilisation des connaissances issues de la recherche, ce qui pourrait favoriser une plus grande utilisation des CIR par les intervenants scolaires. En effet, les résultats de cette recherche peuvent guider les décideurs dans l’implantation des programmes menant à l’utilisation des connaissances issues de la recherche qui s’adressent aux enseignants. Ces résultats indiquent sur quels facteurs agir en premier lieu afin d’améliorer l’utilisation des CIR chez les enseignants du secondaire dans les milieux défavorisés. Le présent modèle pourrait être utilisé dans d’autres milieux scolaires (par exemple les milieux non défavorisés ou les milieux scolaires primaires) après validation.

Internet Banking and Customer Acceptance: The Indian Scenario

Indian economy is witnessing stellar growth over the last few years. There have been rapid developments in infrastructural and business front during the growth period.Internet adoption among Indians has been increasing over the last one decade.Indian banks have also risen to the occasion by offering new channels of delivery to their customers.Internet banking is one such new channel which has become available to Indian customers.Customer acceptance for internet banking has been good so far.In this study the researcher tried to conduct a qualitative and quantitative investigation of internet banking customer acceptance among Indians. The researcher tried to identify important factors that affect customer's behavioral intention for internet banking .The researcher also proposes a research model which has extended from Technology Acceptance Model for predicting internet banking acceptance.The findings of the study would be useful for Indian banks in planning and upgrading their internet banking service.Banks could increase internet banking adoption by making their customer awareness about the usefulness of the service.It is seen that from the study that the variable perceived usefulness has a positive influence on internet banking use,therefore internet banking acceptance would increase when customers find it more usefulness.Banks should plan their marketing campaigns taking into consideration this factor.Proper marketing communications which would increase consumer awareness would result in better acceptance of internet banking.The variable perceived ease of use had a positive influence on internet banking use.That means customers would increase internet banking usage when they find it easier to use.Banks should therefore try to develop their internet banking site and interface easier to use.Banks could also consider providing practical training sessions for customers at their branches on usage of internet banking interface.

A aprendizagem cooperativa como estratégia de inclusão no 1º ciclo

O presente projecto teve como objectivo a realização de uma intervenção, junto de uma turma onde está inserida uma aluna considerada com Necessidades Educativas Especiais, com um diagnóstico de Perturbação por Hiperactividade e Défice de Atenção. No nosso caso, esta intervenção teve lugar numa turma de 1º ciclo constituída por uma diversidade de anos de escolaridade, sendo assim um grupo-turma bastante heterogéneo tanto a nível de aprendizagens como faixas etárias. Esta escola pertence a um agrupamento situado no Norte Alentejano. Tendo em conta que a intervenção necessita de ser adequada, fundamentada e reflectida ao longo de todo o processo, optou-se pela metodologia de investigaçãoacção. Para a recolha e análise de dados preferimos as seguintes técnicas: pesquisa documental, entrevista semi-directiva, observação naturalista e sociometria. Pretendemos, com a nossa intervenção, criar um trabalho de cooperação e colaboração na turma em questão, para que se alcance uma situação de inclusão educativa, em que os alunos aprendem todos e com todos, alcançando assim o sucesso educativo. O nosso trabalho de intervenção, ao basear-nos em práticas de educação inclusivas, permitiu-nos alcançar os objectivos nele propostos.

Farmers' attitudes towards techniques for improving oestrus detection in dairy herds in South West England

Unidentified heats contribute to declining fertility rates in English dairy herds. Several techniques have been advocated to improve heat detection rates. Despite demonstrable technical efficacy and cost-effectiveness, uptake is low. A study in South West England used the Theory of Reasoned Action (TORA) to explore dairy farmers' attitudes and beliefs towards heat detection techniques. Few farmers were convinced that following prescribed observation times, milk progesterone testing and using pedometers would fit their system or improve on their current heat detection practices. Perceived difficulty of using a technique was not a constraint on adoption. Without promotion that addresses identified barriers and drivers to adoption, little change in current practice can be expected. (c) 2006 Elsevier B.V. All rights reserved.

Factors influencing adoption of improved grassland management by small-scale dairy farmers in central Mexico and the implications for future research on smallholder adoption in developing countries

There have been limited recent advances in understanding of what influences uptake of innovations despite the current international focus on smallholder agriculture as a means of achieving food security and rural development. This paper provides a rigorous study of factors influencing adoption by smallholders in central Mexico and builds on findings to identify a broad approach to significantly improve research on and understanding of factors influencing adoption by smallholders in developing countries. Small-scale dairy systems play an important role in providing income, employment and nutrition in the highlands of central Mexico. A wide variety of practices and technologies have been promoted by the government public services to increase milk production and economic efficiency, but there have been very low levels of uptake of most innovations, with the exception of improving grassland through introduction of grass varieties together with management practices. A detailed study was conducted with 80 farmers who are already engaged with the use of this innovation to better understand the process of adoption and identify socioeconomic and farm variables, cognitive (beliefs), and social–psychological (social norms) factors associated with farmers' use of improved grassland. The Theory of Reasoned Action (TRA) was used as a theoretical framework and Spearman Rank Order correlation was conducted to analyse the data. Most farmers (92.5%) revealed strong intention to continue to use improved grassland (which requires active management and investment of resources) for the next 12 months; whereas 7.5% of farmers were undecided and showed weak intention, which was associated with farmers whose main income was from non-farm activities as well as with farmers who had only recently started using improved grassland. Despite farmers' experience of using improved grassland (mean of 18 years) farmers' intentions to continue to adopt it was influenced almost as much by salient referents (mainly male relatives) as by their own attitudes. The hitherto unnoticed longevity of the role social referents play in adoption decisions is an important finding and has implications for further research and for the design of extension approaches. The study demonstrates the value and importance of using TRA or TPB approaches to understand social cognitive (beliefs) and social–psychological (social norms) factors in the study of adoption. However, other factors influencing adoption processes need to be included to provide fuller understanding. An approach that would enable this, and the development of more generalisable findings than from location specific case studies, and contribute to broader conceptualisation, is proposed.

Workaround motivation model (WAMM): an adaptation of the Theory of Interpersonal Behaviour

The study of workarounds (WA) has increased in importance due to their impact on patient safety and efficiency. However, there are no adequate theories to explain the motivation to create and use a workaround in a healthcare sitting. Although theories of technology acceptance help to understand the reasons to accept or reject technology, they fail to explain drivers for alternatives. Also workarounds involve creators and performers that have different motivations. Models such as Theory of Planned Behaviour (TPB) or Theory of Reasoned Action (TRA) can help to explain the role of workaround users, but lack explanation of workaround creators’ dynamics. Our aim is to develop a theoretical foundation to explain workaround motivation behaviour models with norms that relate to sanctions to provide an integrated Workaround Motivation Model; WAMM. The development of WAMM model is explained in this paper based on workaround cases as part of further research to establish the model.

Valores, atitudes e intenção empreendedora: um estudo com universitários brasileiros e cabo-verdianos

A presente pesquisa apresentou como seu objetivo principal verificar as relações entre valores, atitude em relação ao empreendedorismo (AE) e intenção empreendedora (IE) em um estudo comparativo com universitários de graduação em Administração das Cinco Regiões Brasileiras e Cabo Verde. O instrumento de pesquisa foi composto por um questionário sócio demográfico, a escala de Valores Humanos – Questionário de Perfis de Valores de Schwartz(2001) e o Questionário de Intenção Empreendedora de Liñán & Chen (2009). Após o consentimento livre e informado, os alunos responderam o instrumento de pesquisa, perfazendo um total de 1561 respostas válidas. Os dados foram tabulados e analisados nos Softwares: SPSS 21 e AMOS 21 para a produção de Estatísticas Descritivas, Análises de Confiabilidade, Análises de Correlação, Análise de Variância (ANOVA), Gráficos, Análise Fatorial Confirmatória e Modelagem de Equações Estruturais (SEM). Os modelos utilizaram a Teoria de Ação Racional (FISHBEIN & AJZEN,1971) e Teoria do Comportamento Planejado(AJZEN,1991), testando o impacto dos valores nas atitudes e intenções. Os resultados indicaram que os valores de Estimulação, Poder e Hedonismo foram tiveram os maiores efeitos na IE e na AE. Diferenças significativas foram encontradas entre os gêneros, com os homens apresentando maior IE e AE. Diferenças regionais foram encontradas. Limitações, implicações práticas e teóricas, além de sugestões para pesquisas futuras são apresentadas.

Service Utilization Patterns of Homeless Youth

Few studies exist on the types of characteristics associated with service utilization (e.g., shelters, food programs) among homeless youth in the U.S. Services are important, however, because without food and shelter, numerous homeless youth resort to trading sex in order to meet their daily survival needs. Access to physical and mental health services gives homeless youth more of an opportunity to integrate into mainstream society than they would otherwise have. To address this gap in our understanding, my study examines what traits (e.g. age, race, abuse history) correlate with the use of shelters, food programs, street outreach, counseling, STD/STI testing, and HIV testing among homeless youth. The Theory of Reasoned Action is used as an ideological framework in conjunction with theoretical constructs of risk, need, and prior service exposure. Data were obtained from the Social Network and Homeless Youth Project (SNHYP), a sample of 249 Midwestern homeless youth ages 14 to 21, which used trained interviewers to conduct structured interviews with youth. Respondents were interviewed in both shelters and on the street over a period of approximately one year. My findings revealed that homeless youth’s service usage varied across gender, sexual orientation, age, having recently held a job, and having ever been physically or sexually abused, in addition to other characteristics. Conversely, service use was not associated with social network size or subjective norms (i.e. attitudes of peers, such as acceptance of condom use) of youths’ social networks. By examining these areas, my study builds on previous research on homeless youth and lays the framework for future research on service utilization by homeless youth.

Behavioral and psychosocial factors associated with sexual risk in a population of crack cocaine users

The purpose of this dissertation was to examine the relationship between key psychosocial and behavioral components of the Transtheoretical Model and the Theory of Reasoned Action for sexual risk reduction in a population of crack cocaine smokers and sex workers, not in drug treatment. ^ The first study examined the results of an analysis of the association between two principal constructs in the Transtheoretical Model, the processes of change and the stages of change for condom use, in a high risk population. In the analysis of variance for all respondents, the overall F-test revealed that people in different stages have different levels of experiential process use, F(3,317) = 17.79, p = 0.0001 and different levels of behavioral process use, F(3,317) = 28.59, p = .0001. For the experiential processes, there was a significant difference between the precontemplation/contemplation stage, and both the action, and maintenance, stages.^ The second study explored the relationship between the Theory of Reasoned Action “beliefs” and the stages-of-change in the same population. In the analysis of variance for all participants, the results indicate that people in different stages did value the positive beliefs differently, F(3,502) = 15.38, p = .0001 but did not value the negative beliefs differently, F(3,502) = 2.08, p = .10. ^ The third study explored differences in stage-of-change by gender, partner type drug use, and HIV status. Three discriminant functions emerged, with a combined χ2(12) = 139.57, p = <.0001. The loading matrix of correlations between predictors and discriminant functions demonstrate that the strongest predictor for distinguishing between the precontemplation/contemplation stage and the preparation, action, and maintenance stages (first function) is partner type (.962). The loadings on the second discriminant function suggest that once partner type has been accounted for, ever having HIV/AIDS (.935) was the best predictor for distinguishing between the first three stages and the maintenance stage. ^ These studies demonstrate that behavioral change theories can contribute important insight to researchers and program planners attempting to alter HIV risk behavior in high-risk populations. ^

Health promotion attitudes and practices of Texas nurse practitioners

The purpose of this descriptive cross-sectional survey was to examine the health promotion attitudes and practices of Texas nurse practitioners and to evaluate the applicability of the Theory of Reasoned Action and the Theory of Planned Behavior as a theoretical model to guide nurse practitioner health promotion research. A questionnaire developed to elicit responses regarding demographic information, practice characteristics, behavior, behavior intention, attitudes toward health promotion, subjective norm and perceived behavioral control for health promotion practices was mailed to the home address of 727 Texas nurse practitioners. The majority of the 442 respondents reported positive attitudes toward health promotion. Texas nurse practitioners provide health promotion for more than 50% of their patients. Significant barriers to the provision of health promotion cited by Texas nurse practitioners were lack of time, lack of reimbursement and lack of patient desire to change behavior. The findings of this study support the use of the Theory of Reasoned Action and the Theory of Planned Behavior in nurse practitioner research. ^

Evaluation of the causal pathways through which subjective norms influence mammography intention and stage of change in a national sample of women veterans

Few studies have investigated causal pathways linking psychosocial factors to each other and to screening mammography. Conflicting hypotheses exist in the theoretic literature regarding the role and importance of subjective norms, a person's perceived social pressure to perform the behavior and his/her motivation to comply. The Theory of Reasoned Action (TRA) hypothesizes that subjective norms directly affect intention; while the Transtheoretical Model (TTM) hypothesizes that attitudes mediate the influence of subjective norms on stage of change. No one has examined which hypothesis best predicts the effect of subjective norms on mammography intention and stage of change. Two statistical methods are available for testing mediation, sequential regression analysis (SRA) and latent variable structural equation modeling (LVSEM); however, software to apply LVSEM to dichotomous variables like intention has only recently become available. No one has compared the methods to determine whether or not they yield similar results for dichotomous variables. ^ Study objectives were to: (1) determine whether the effect of subjective norms on mammography intention and stage of change are mediated by pros and cons; and (2) compare mediation results from the SRA and LVSEM approaches when the outcome is dichotomous. We conducted a secondary analysis of data from a national sample of women veterans enrolled in Project H.O.M.E. (H&barbelow;ealthy O&barbelow;utlook on the M&barbelow;ammography E&barbelow;xperience), a behavioral intervention trial. ^ Results showed that the TTM model described the causal pathways better than the TRA one; however, we found support for only one of the TTM causal mechanisms. Cons was the sole mediator. The mediated effect of subjective norms on intention and stage of change by cons was very small. These findings suggest that interventionists focus their efforts on reducing negative attitudes toward mammography when resources are limited. ^ Both the SRA and LVSEM methods provided evidence for complete mediation, and the direction, magnitude, and standard errors of the parameter estimates were very similar. Because SRA parameter estimates were not biased toward the null, we can probably assume negligible measurement error in the independent and mediator variables. Simulation studies are needed to further our understanding of how these two methods perform under different data conditions. ^

The care to share HIV disclosure study - the attitudes toward and beliefs about HIV disclosure among perinatally-infected HIV-positive youth and their caregivers

HIV incidence has not changed since the introduction of the pandemic. Daily 14,000 persons are infected with HIV and 25 to 50% of the HIV-infected population and subgroups respectively are estimated to be unaware of their HIV diagnosis. Perinatally-infected HIV-positive youth, aged 13-24 years, have survived unexpectedly into adulthood, have had unique HIV disclosure experiences and now face HIV disclosure issues of adulthood and perhaps parenthood. Despite new effective HIV therapies, no HIV prevention plan exists that has diminished the rate of new HIV infections. HIV stigma and lack of universal HIV reporting laws dissuade timely HIV disclosure. Missed HIV disclosure perpetuates HIV transmission and infection. Understanding the attitudes and beliefs of HIV disclosure among perinatally-infected HIV-positive youth and their caregivers may uncover reasons to HIV disclosure delays, avoidance and intentions. The Care to Share HIV Disclosure study was designed to identify the attitudes and beliefs of HIV disclosure among HIV-positve youth (aged 13-24 years), who were infected from birth and who knew their HIV diagnosis, along with their caregivers. Twenty-six participants (15 youth and 11 caregivers) completed the theory-based questionnaires of a 21-item multiple choice survey on HIV disclosure framed in the Theory of Reasoned Action and Theory of Planned Behavior and included an additional open-ended survey that applied the Transactional Model of Stress and Coping to address youth's and caregivers' HIV disclosure experiences. Youth were found to have a selective unfavorable HIV disclosure outcome when among referents of close friends. However youth did believe in HIV partner notification. For caregivers, it mattered who disclosed the HIV illness to the youth. HIV stigma was of concern based on the youths' tendency to believe in keeping HIV a secret and their caregivers' ambivalence to HIV secrecy. However, favorable HIV disclosure outcomes were identified for both youth and caregivers the potential for HIV disclosure: when seeking HIV knowledge, when around caregivers and close family and in situations of perceived controllability as when helping others learn about HIV. These findings unveil HIV disclosure attitudes and beliefs within this population and may reveal the attributes that may inhibit or promote HIV disclosure behaviors. HIV disclosure studies that address attitudes and beliefs among larger populations of youth and HIV-infected persons are necessary to identify effective individual, group and society approaches that would promote timely, responsible and meaningful HIV disclosure methods that promote a healthy identity and interrupt HIV transmission.^

Something real: A social marketing approach to smoking prevention among Montevideo youth

Uruguay has some of the strictest tobacco-control laws in Latin America. Despite this, youth smoking rates in Uruguay are amongst the highest in South America. Thus, it is important to identify strategies to prevent youth smoking in Uruguay. The current qualitative research study sought to identify intrapersonal and socioenvironmental factors that are associated with smoking among middle school youth in Uruguay. It also sought to develop potential prevention strategies and media messages that would resonate with youth for a social media campaign. The study was grounded in social cognitive theory and the theory of reasoned action/planned behavior, among other behavioral science theories; anthropological perspectives were also considered. To achieve these goals, 29 group and individual structured interviews were conducted in two private middle schools catering to lower and higher SES youth in Montevideo, Uruguay during the summer of 2012. One hundred and three study participants, including students, parents, and teachers, were interviewed. The structured interviews were recorded, transcribed, translated, back translated, coded and analyzed. The study findings show that positive attitudes towards smoking (i.e. to be seen, to increase status, to ensure women's equality, to looking old, and to service as a rite of passage), delinquent behavior (i.e. transgression/deviant behavior), social norms that support smoking (i.e. peer pressure and modeling, group membership/sense of belonging, parental modeling, and family support), easy access and availability to tobacco (i.e. retails stores) were factors associated with youth smoking. Potential protective factors may include parental support, negative attitudes towards smoking, sports/music, and smoke-free environments. Because study participants are accustomed to government-sponsored strong countermarketing graphic imaging, study participants selected even stronger images and messages as the preferred way to receive tobacco prevention messages. Something Real ("Algo Real") was a theme that resonated with the participants and chosen as the name for the proposed campaign. This campaign was designed as a multiple component intervention that included mass, school base, and family based strategies to prevent tobacco use. Some intervention materials specific to these intervention components were developed to target relevant intrapersonal and socioenvironmental factors identified above. These materials will be tested in future pilot studies and larger scale evaluation with this population, outside the scope of this dissertation. ^

Predicting smokeless tobacco cessation in a blue -collar population

The use of smokeless tobacco products is undergoing an alarming resurgence in the United States. Several national surveys have reported a higher prevalence of use among those employed in blue-collar occupations. National objectives now target this group for health promotion programs which reduce the health risks associated with tobacco use.^ Drawn from a larger data set measuring health behaviors, this cross-sectional study tested the applicability of two related theories, the Theory of Reasoned Action (TRA) and the Theory of Planned Behavior (TPB), to smokeless tobacco (SLT) cessation in a blue-collar population of gas pipeline workers. In order to understand the determinants of SLT cessation, measures were obtained of demographic and normative characteristics of the population and specific constructs. Attitude toward the act of quitting (AACT) and subjective norm (SN) are constructs common to both models, perceived behavioral control (PBC) is unique to the TPB, and the number of past quit attempts is not contained in either model. In addition, a self-reported measure was taken of SLT use at two-month follow-up.^ The study population was comprised of all male SLT users who were field employees in a large gas pipeline company with gas compressor stations extending from Texas to the Canadian border. At baseline, 199 employees responded to the SLT portion of the survey, 118 completed some portion of the two-month follow-up, and 101 could be matched across time.^ As hypothesized, significant correlations were found between constructs antecedent to AACT and SN, although crossover effects occurred. Significant differences were found between SLT cessation intenders and non-intenders with regard to their personal and normative beliefs about quitting as well as their outcome expectancies and motivation to comply with others' beliefs. These differences occurred in the expected direction, with the mean intender score consistently higher than that of the non-intender.^ Contrary to hypothesis, AACT predicted intention to quit but SN did not. However, confirmatory of the TPB, PBC, operationalized as self-efficacy, independently contributed to the prediction of intention. Statistically significant relationships were not found between intention, perceived behavioral control, their interactive effects, and use behavior at two-month follow-up. The introduction of number of quit attempts into the logistic regression model resulted in insignificant findings for independent and interactive effects.^ The findings from this study are discussed in relation to their implications for program development and practice, especially within the worksite. In order to confirm and extend the findings of this investigation, recommendations for future research are also discussed. ^
