Development of the Sphere Overlap Scale (SOS) : compartmentalization and the spillover hypothesis

The purpose of this study was to create a scale that could measure compartmentalization. In the first of two studies 311 working undergraduates were asked to indicate agreement with 119 items that measured compartmentalization. The resulting scale's reliability and validity were evaluated by having a second sample of 312 working students complete the items that comprise a sphere overlap scale, two measures of spillover, and a measure of personality, coping, and demoralization. Although the study's original goal was not realized, its procedures were successful in developing a short (10-item) measure of work-to-home spillover whose items loaded on a single factor. Structural equation modeling indicated that SOS items were correlated with existing measures of spillover and could be discriminated from related concepts of personality and coping. The SOS was also more highly correlated with demoralization than existing measures of spillover in hierarchical analyses that controlled for demographic factors, personality characteristics, and coping style. It is concluded that the SOS shows enough promise to warrant the cost of its appraisal as an alternative measure of spillover in a longitudinal study.

Relations Between Acculturation And Alcohol Use Among International Students

In the current study, 226 international students attending Florida International University responded to an Web-based questionnaire that assessed self-reported scores for: acculturation, acculturative stress, alcohol use patterns, perceived peer alcohol use, and perceived injunctive social norms for alcohol use. The purpose of the study was to evaluate structural relations among this set of variables using Structural Equation Modeling (SEM) via AMOS 17.0. The results of SEM analyses documented acceptable fit of a model which hypothesized that relations between acculturation and alcohol use variables are mediated partially by acculturative stress, perceived peer alcohol use, and perceived injunctive social norms. While significant path coefficients were documented for paths between (a) acculturation and acculturative stress and (b) acculturative stress and alcohol use, the coefficients had negative signs, contrary to existing studies investigating these relations among immigrant youth. While paths between (a) perceived peer alcohol use or (b) perceived injunctive social norms and participants’ alcohol use were significant, path coefficients between acculturation and either (a) perceived peer alcohol use or (b) perceived injunctive social norms were not statistically significant. In addition, multiple-group comparisons suggested that social support had a significant moderating influence on several significant paths in the structural model. Specifically, international students reporting higher social support reported lower scores for acculturative stress and alcohol use, in contrast to their counterparts who reported lower scores for social support.

A model of self-transformative identity development in troubled adolescent youth

Within the Stage II program evaluation of the Miami Youth Development Project's (YDP) Changing Lives Program (CLP), this study evaluated CLP intervention effectiveness in promoting positive change in emotion-focused identity exploration (i.e. feelings of personal expressiveness; PE) and a "negative" symptom of identity development (i.e. identity distress; ID) as a first step toward the investigation of a self-transformative model of identity development in adolescent youth. Using structural equation modeling techniques, this study found that participation in the CLP is associated with positive changes in PE (path = .841, p < .002), but not changes in ID. Increase in ID scores was found to be associated with increases in PE (path = .229, p < .002), as well. Intervention effects were not moderated by age/stage, gender, or ethnicity, though differences were found in the degree to which participating subgroups (African- American/Hispanic, male/female, 14-16 years old/17-19 years old) experience change in PE and ID. Findings also suggest that moderate levels of ID may not be deleterious to identity exploration and may be associated with active exploration.

Antecedentes da intenção de uso de comentários de viagem on-line na escolha de um meio de hospedagem

The Internet is present in each step of a trip planning. The constant technological advances has made major changes in the tourism industry. This is noticeable by the growing number of people who share their travel experiences on the Internet. This study has aimed to analyze the factors that influence the use of the Online Travel Reviews (OTR) in choosing an accommodation. It was done an investigation into the comments available on the internet about information on touristic products and services, specifically about accommodations. The research proposed to understand the influencing factors of OTR, in the Brazilian context, through the Technology Acceptance Model, Motivational Theory, Similarity, and Trustworthiness. The methodology used was a descriptive-exploratory study, with a quantitative approach, and bibliographic research. The study used a Structural Equation Modeling technique called Partial Least Squares (PLS), to test and evaluate the proposed research model. Data collection was performed with 308 guests hosted in five hotels in Ponta Negra (Natal/RN), who have used the OTRs in choosing an accommodation. The research tested fifteen hypotheses, where nine were confirmed, and six were rejected. The results showed that guests have attitude and intention to use the OTRs to choose an accommodation.

Antecedentes do engajamento em boca a boca eletrônico positivo entre turistas

This study examined the influence of the tourism destination image as well as satisfaction and motivation in the intention of engaging in a positive electronic word of mouth (eWOM) by tourists through Facebook. In addition, it was also specifically expected to assess the sociodemographic profile and frequency of eWOM publications from those who answered the questions; it also assessed the adequacy of the manifested variables for composition of the following dimensions: Quality, Satisfaction, Image, Motivations and Positive Electronic Word of Mouth (eWOM). And finally, it analyzed a relational model where there are relationships between Quality, Satisfaction, Image and Motivations in the explanation of engagement in the Positive Electronic Word of Mouth (eWOM). With this aim it was conducted a study, based on a hypothetical-deductive logic, which was descriptive in relation to its goals. The analytical approach was quantitative (a survey). The sampling procedure was non-probabilistic, by the convenience method of sampling specifically, having the choice of the subject been made through the probabilistic systematic method, and using time as a factor of systematization in an attempt of making randomly the selection of the interviewed people. The study sample consisted of 355 tourists. The used instrument to collect information was the structured questionnaire whose answers were collected in the main points of entry, exit and rides of tourists on the Pipa’s Beach/RN. Data analysis was carried out using descriptive and multivariate statistics, mainly exploratory and confirmatory factor analysis and structural equation modeling. Among the main results, it was possible to confirm that the Motivations, Satisfaction and Image strongly affect the intention of engaging in positive electronic word of mouth (eWOM). Emphasis is given to the motivations, as they demonstrate bigger impact in explaining the dependent variable; they are followed by the satisfaction and the image. The latter, however, is inversely proportional. Among the motivations, the one with the highest percentage of variance were the social benefits sought by tourists; and presenting the same percentage appears the desire to help other tourists and to vent Positive Emotions. The manifested variables demonstrate to be fully acceptable to be taken as reflexes of their respective factors.

Is socioeconomic position early in life associated with physical activity during adulthood following the accumulation of risk model with additive effects?

L'activité physique améliore la santé, mais seulement 4.8% des Canadiens atteignent le niveau recommandé. La position socio-économique est un des déterminants de l'activité physique les plus importants. Elle est associée à l’activité physique de manière transversale à l’adolescence et à l’âge adulte. Cette thèse a tenté de déterminer s'il y a une association à long terme entre la position socio-économique au début du parcours de vie et l’activité physique à l’âge adulte. S'il y en avait une, un deuxième objectif était de déterminer quel modèle théorique en épidémiologie des parcours de vie décrivait le mieux sa forme. Cette thèse comprend trois articles: une recension systématique et deux recherches originales. Dans la recension systématique, des recherches ont été faites dans Medline et EMBASE pour trouver les études ayant mesuré la position socio-économique avant l'âge de 18 ans et l'activité physique à ≥18 ans. Dans les deux recherches originales, la modélisation par équations structurelles a été utilisée pour comparer trois modèles alternatifs en épidémiologie des parcours de vie: le modèle d’accumulation de risque avec effets additifs, le modèle d’accumulation de risque avec effet déclenché et le modèle de période critique. Ces modèles ont été comparés dans deux cohortes prospectives représentatives à l'échelle nationale: la 1970 British birth cohort (n=16,571; première recherche) et l’Enquête longitudinale nationale sur les enfants et les jeunes (n=16,903; deuxième recherche). Dans la recension systématique, 10 619 articles ont été passés en revue par deux chercheurs indépendants et 42 ont été retenus. Pour le résultat «activité physique» (tous types et mesures confondus), une association significative avec la position socio-économique durant l’enfance fut trouvée dans 26/42 études (61,9%). Quand seulement l’activité physique durant les loisirs a été considérée, une association significative fut trouvée dans 21/31 études (67,7%). Dans un sous-échantillon de 21 études ayant une méthodologie plus forte, les proportions d’études ayant trouvé une association furent plus hautes : 15/21 (71,4%) pour tous les types et toutes les mesures d’activité physique et 12/15 (80%) pour l’activité physique de loisir seulement. Dans notre première recherche originale sur les données de la British birth cohort, pour la classe sociale, nous avons trouvé que le modèle d’accumulation de risque avec effets additifs s’est ajusté le mieux chez les hommes et les femmes pour l’activité physique de loisir, au travail et durant les transports. Dans notre deuxième recherche originale sur les données canadiennes sur l'activité physique de loisir, nous avons trouvé que chez les hommes, le modèle de période critique s’est ajusté le mieux aux données pour le niveau d’éducation et le revenu, alors que chez les femmes, le modèle d’accumulation de risque avec effets additifs s’est ajusté le mieux pour le revenu, tandis que le niveau d’éducation ne s’est ajusté à aucun des modèles testés. En conclusion, notre recension systématique indique que la position socio-économique au début du parcours de vie est associée à la pratique d'activité physique à l'âge adulte. Les résultats de nos deux recherches originales suggèrent un patron d’associations le mieux représenté par le modèle d’accumulation de risque avec effets additifs.

Spontaneity and international marketing performance

Purpose: The purpose of this paper is to ascertain how today’s international marketers can perform better on the global scene by harnessing spontaneity. Design/methodology/approach: The authors draw on contingency theory to develop a model of the spontaneity – international marketing performance relationship, and identify three potential moderators, namely, strategic planning, centralization, and market dynamism. The authors test the model via structural equation modeling with survey data from 197 UK exporters. Findings: The results indicate that spontaneity is beneficial to exporters in terms of enhancing profit performance. In addition, greater centralization and strategic planning strengthen the positive effects of spontaneity. However, market dynamism mitigates the positive effect of spontaneity on export performance (when customer needs are volatile, spontaneous decisions do not function as well in terms of ensuring success). Practical implications: Learning to be spontaneous when making export decisions appears to result in favorable outcomes for the export function. To harness spontaneity, export managers should look to develop company heuristics (increase centralization and strategic planning). Finally, if operating in dynamic export market environments, the role of spontaneity is weaker, so more conventional decision-making approaches should be adopted. Originality/value: The international marketing environment typically requires decisions to be flexible and fast. In this context, spontaneity could enable accelerated and responsive decision-making, allowing international marketers to realize superior performance. Yet, there is a lack of research on decision-making spontaneity and its potential for international marketing performance enhancement.

Climat motivationnel en éducation physique et besoins psychologiques : impact sur les buts d’accomplissement, les attitudes et les habitudes des élèves

Pour permettre de mieux comprendre la problématique du désengagement des adolescents en éducation physique et aussi à l’endroit de l’activité physique en général, la présente étude avait pour objectif d’examiner les liens entre, d’une part, le climat motivationnel en classe d’éducation physique (maîtrise et performance) et les besoins psychologiques des élèves des deux sexes (compétence, autonomie et appartenance) et, d’autre part, les buts d’accomplissement (maîtrise, performance-approche et performance-évitement) poursuivis en éducation physique. Elle visait aussi à examiner l’impact des buts d’accomplissement sur les attitudes et habitudes des adolescents à l’endroit de l’activité physique en général. Pour atteindre ces objectifs, 909 élèves (âge moyen = 13,87[0,94]) ont rempli des questionnaires à items auto-révélés à trois reprises pendant l’année scolaire. Des modèles d’équations structurelles (AMOS 22), des analyses d’invariance ainsi que l’approche sans contrainte ont servi à analyser les données. Les résultats indiquent que les buts d’accomplissement des élèves varient en fonction du climat motivationnel perçu et que le sentiment de compétence entretient une relation positive avec les trois buts d’accomplissement. Ces relations étaient invariantes selon le sexe des élèves. Par ailleurs, une seule interaction climat-besoin s’est avérée significative : l’interaction entre le climat de maîtrise et le sentiment d’autonomie prédit négativement l’adoption de buts de performance-évitement. Cela signifie que la perception d’un climat de maîtrise réduit l’adoption de buts de performance-évitement par les élèves, mais seulement lorsque ceux-ci affichent un fort sentiment d’autonomie. Finalement, l’adoption de buts de maîtrise et de buts de performance-approche en éducation physique exerce une influence positive sur les attitudes des élèves qui, à leur tour, influencent leurs habitudes en activité physique. Seule l’adoption de buts de performance-approche entretient une relation positive directe avec les habitudes des élèves. En conclusion, l’enseignant d’éducation physique peut agir sur la motivation et l’engagement des élèves en classe, mais aussi à l’extérieur des cours, en instaurant un climat motivationnel de maîtrise et en aidant les élèves à satisfaire leur besoin de compétence.

An Examination of Race, Socioeconomic Status, and Individualism-Collectivsm as Moderators of the Work/Family Antecedent and Work-Family Conflict Relationship

This study examines the role of race, socioeconomic status, and individualism-collectivism as moderators of the relationship between selected work and family antecedents and work-family conflict and evaluates the contribution of energy-based conflict to the work-family conflict (WFC) research. The study uses data obtained from a survey questionnaire given to 414 participants recruited from an online labor market. Study hypotheses were tested through structural equation modeling. The results indicate that while moderating effects were slight, a proposed model where energy-based conflict is included outperforms traditional time/strain/behavior-based models and that established variables may drop to non-significance when additional variables are included in prediction. In addition, novel individual difference variables such as individualism and collectivism were demonstrated to have effects beyond moderating antecedent-outcome relationships in the model. The findings imply that WFC models would benefit from the inclusion of variables found in the current study.

Identity, Purpose, and Well-Being Among Emerging Adult Hispanic Women

Few studies apply the Eriksonian model of identity formation to cross-cultural samples (3), even though issues of ethnicity and culture may inform a Hispanic woman’s self-concept (Phinney, 1996). Hispanic women may also be influenced by traditional gender role behaviors such as passivity or dependence that are outlined by marianismo (Stevens, 1973). A recent study of a multiethnic sample of emerging adult women and men found that purpose commitment mediated the effects of identity commitment on hope and life satisfaction (Burrow & Hill, 2011). The current research consists of two studies that replicate and expand upon the work of Burrow and Hill (2011). Study I replicated the work of Burrow and Hill (2011) among a sample of emerging adult Hispanic women, in order to assess the extent to which the original findings would replicate in a culturally distinct sample. Study II examined the role of marianismo, ethnic identity, and acculturation on identity commitment among emerging adult Hispanic women. Both studies utilized a sample of 532 female undergraduate psychology students, age 18 to 25, who self-identified as Hispanic and submitted data via online surveys. Both studies used self-report, quantitative data, which was analyzed using structural equation modeling. Results from Study I indicated good model fit and replicated the findings from Burrow and Hill (2011). Specifically, the direct effect of identity commitment on hope was fully contingent upon an individual’s level of purpose commitment, while the effect of identity commitment on life satisfaction was not contingent upon an individual’s level of purpose commitment. Results from Study II indicated that marianismo, Spanish proficiency, familiarity with Latino culture, and familiarity with American culture demonstrated statistically significant direct effects on identity commitment among emerging adult Hispanic women. Results indicated cultural convergence regarding the association of an individual’s identity with well-being through a sense of purpose. Findings also revealed the role of cultural factors in the extent to which Hispanic women commit to a personal identity. Future studies should employ mixed method research designs as a means to better ascertain implications of findings.

Extending the Theory of Planned Behavior in the Exercise Domain: A Study of Community College Students in an Urban Multicultural Setting

The purpose of this study was to assess the intention to exercise among ethnically and racially diverse community college students using the Theory of Planned Behavior (TPB). In addition to identifying the variables associated with motivation or intention of college students to engage in physical activity, this study tested the model of the Theory of Planned Behavior, asking: Does the TPB model explain intention to exercise among a racially/ethnically diverse group of college students? The relevant variables were the TPB constructs (behavioral beliefs, normative beliefs, and control beliefs), which combined to form a measure of intention to exercise. Structural Equation Modeling was used to test the predictive power of the TPB constructs for predicting intention to exercise. Following procedures described by Ajzen (2002), the researcher developed a questionnaire encompassing the external variables of student demographics (age, gender, work status, student status, socio-economic status, access to exercise facilities, and past behavior), major constructs of the TPB, and two questions from the Godin Leisure Time Questionnaire (GLTQ; Godin & Shephard, 1985). Participants were students (N = 255) who enrolled in an on-campus wellness course at an urban community college. The demographic profile of the sample revealed a racially/ethnically diverse study population. The original model that was used to reflect the TPB as developed by Ajzen was not supported by the data analyzed using SEM; however, a revised model that the researcher thought was theoretically a more accurate reflection of the causal relations between the TPB constructs was supported. The GLTQ questions were problematic for some students; those data could not be used in the modeling efforts. The GLTQ measure, however, revealed a significant correlation with intention to exercise (r = .27, p = .001). Post-hoc comparisons revealed significant differences in normative beliefs and attitude toward exercising behavior between Black students and Hispanic students. Compared to Black students, Hispanic students were more likely to (a) perceive “friends” as approving of them being physically active and (b) rate being physically active for 30 minutes per day as “beneficial”. No statistically significant difference was found among groups on overall intention to exercise.

Cognitive behavior therapy for anxiety disorders in youth: Treatment specificity and mediation effects

The present study investigated the efficacies of Individual CBT (ICBT), Parent Relationship Skill Training (RLST, which targets increasing parental acceptance of youth and increasing autonomy granting) and Parent Reinforcement Skills Training (RLST, which targets increasing parental positive reinforcement and decreasing negative reinforcement). The specific aims were to examine treatment specificity and mediation effects of parenting variables. ICBT was used as a baseline comparison condition. The sample consisted of 253 youth (ages 5-16 years; M = 9.38; SD = 2.42) and their parents. To examine treatment outcome and specificity, the data were analyzed using analysis of variance within a structural equation modeling framework. Mediation was analyzed via structural equation modeling using MPlus. Results indicated that ICBT, RLST, and RFST produced positive treatment outcomes across all indices of change (i.e., clinically significant improvement, anxiety symptom reduction) and across all informants (i.e., youths and parents). RLST was associated with incremental reduction in youth anxiety symptoms beyond ICBT, as per youth report. Treatment specificity effects were found for participants in RFST in terms of parental reinforcement, as per parent report only. Treatment mediation was not found for any of the hypothesized parenting variables (i.e., parental acceptance, parental autonomy granting, parental reinforcement). The results support the use of CBT involving only the youth and the parent and youth together for treating youth anxiety. The findings’ implications are further discussed in terms of the need to conduct further meditational treatment outcome designs in order to continue to advance theory and research in youth anxiety treatment.

The Social Environment in Children’s Sport: Cohesion, Social Acceptance, Commitment, and Enjoyment

The primary purpose of the current study was to determine whether perceptions of cohesion mediated the relationship between social acceptance and individual commitment and enjoyment in children’s sport. A secondary purpose involved the assessment of the temporal nature of cohesion over the course of an athletic season. A total of 209 (Mage = 9.87 years; SD = 1.34) recreational soccer players completed questionnaires at three time points (T1 – social acceptance, cohesion; T2 – cohesion; T3 – commitment, enjoyment, cohesion) during an athletic season. Using structural equation modeling, the results indicated that task cohesion mediated the relationship between social acceptance and commitment and enjoyment, whereas social cohesion did not. In addition, individual perceptions of cohesion did not vary significantly over the course of the season. These results will be discussed in terms of their theoretical and practical implications. As one example, the relative stability in terms of perceptions of cohesion in this population could inform future intervention work aimed at enriching the social environment

The effects of trade show environments on visitors

Tourism trade shows that are open to the public as well as to buyers and sellers are an emerging channel for the promotion of products to potential tourists. However, few studies have explored the influence of environmental stimuli on non-business visitors’ emotions. Moreover, the moderating effect of visitors’ expectations remains under-studied in the context of trade show management. To address this issue, this study reports on research derived from 611 respondents at a Taiwanese tourism trade show through a modified Mehrabian-Russell model. Structural equation modeling of the data shows that positive emotions positively influence behavioral intentions, but negative emotions do not negatively influence behavioral intentions. Among the three stimuli (i.e., information rate, service staff quality, and atmospherics), only information rate and service staff quality positively affect positive emotions and negatively affect negative emotions. The results show that visitors with high and low trade show visit expectations react differently to environmental stimuli at trade shows.
