Mediating Variables (mediating + variable)
Selected AbstractsChild Weight Status and Young Adult Quality of Life: Is There a Reason for Concern?FAMILY & CONSUMER SCIENCES RESEARCH JOURNAL, Issue 1 2008Holly S. Kihm The purpose of the study was to examine the relationship between child weight status and young adult quality of life. One hundred sixty-four college students participated in the study. Students completed four questionnaires that were used to assess physical and psychosocial variables. Several statistical analyses, including correlations and hierarchal regression models, were employed to test the study's hypotheses. Results from the study showed that child weight status was negatively associated with adult quality of life, and child self-concept was a mediating variable within the relationship. Recognizing the relationship between child weight status and young adult quality of life stresses the importance of addressing psychosocial concerns related to weight status during childhood in efforts to achieve a greater quality of life in adulthood. [source] The effect of learning organization culture on the relationship between interpersonal trust and organizational commitmentHUMAN RESOURCE DEVELOPMENT QUARTERLY, Issue 2 2009Ji Hoon Song The primary purpose of this research was to assess the effect of learning organization culture on the linkage between interpersonal trust and organizational commitment. The study sample was obtained from employees of two major Korean conglomerates. Online questionnaires were completed by 321 respondents. Structural equation modeling (SEM) was used to detect the effects of learning organization culture on the basis of the model fit to data comparisons and the significance of path coefficient estimates in the hypothesized model. The results suggest that learning organization culture works as a mediating variable to explain the association between interpersonal trust and organizational commitment. Recommendations for future research and implications for human resource development research and practice are discussed. [source] An Examination of the Effects of WebTrust and Company Type on Consumers' Purchase IntentionsINTERNATIONAL JOURNAL OF AUDITING, Issue 2 2003Steven E. Kaplan This study examines the effects of both WebTrust and company type on purchasing intentions in a B2C E-commerce setting. While past studies have focused on the incremental effects of Web assurance services on Web sites, this study extends research by exploring whether WebTrust strengthens purchasing intentions for both known, and unknown, companies. Professional literature suggests that Web assurance seals such as WebTrust will primarily benefit unknown companies. A second contribution of the paper is to propose and test a model of how WebTrust and company type each lead to greater purchasing intentions. Based on a mediation model, WebTrust is expected to influence purchasing intentions through assurance beliefs. Alternatively, company type is expected to influence purchasing intentions through the formation of trusting beliefs. Under our model, because each works through a separate mediating variable, WebTrust and company type are not substitutes for each other. The results support the proposed model showing that WebTrust is mediated by assurance beliefs and company type is mediated by trusting beliefs. These results have important practical implications as they show that all companies, not just the unknown, can benefit from displaying a WebTrust seal. Thus, the results from our study suggest that the potential market for Web assurance services should include all B2C E-commerce companies. [source] Self-Objectification and Exercise Behaviors: The Mediating Role of Social Physique AnxietyJOURNAL OF APPLIED BIOBEHAVIORAL RESEARCH, Issue 3-4 2007Lise Melbye Self-objectification (SO) and Social Physique Anxiety (SPA) were investigated in relation to reported exercise behaviors (EBs). A conceptual model was used in which SPA was posited as a mediating variable between SO and EBs categorized as protective or permissive. Two hundred and ninety-one women (age range = 18,74 years) completed the SO, SPA, and EB questionnaires. Women lower in SO reported exercising more, wearing more concealing exercise apparel, and preferring outdoors locations. The models were found to fit the data adequately, but only the path from SO to SPA was significant. These results reaffirm the relationship between SO and SPA, but further understanding of the potential effects of SO on behaviors involving health, body, and exercise is required. [source] An investigation of the correlations between aggression, impulsiveness, social problem-solving, and alcohol useAGGRESSIVE BEHAVIOR, Issue 6 2002Mary McMurran Abstract Impulsivity has been shown to predict aggression and heavy drinking in males, and poor social problem-solving has been identified as a potential mediating variable in this relationship. We set out to investigate the inter-relationships among impulsiveness, social problem-solving, aggression, and alcohol use in a non-offender sample of British males (N=70). Of our proposed relationships, only two were significant: higher impulsivity was related to poorer social problem-solving, and poorer social problem-solving was related to greater aggression. Combining impulsivity and social problem-solving indicated that poor social problem-solving, not impulsivity, was what exerted the influence over aggression in this sample. Impulsivity perhaps presents an obstacle to learning in the early developmental years, and the legacy of poor problem-solving is what later contributes to aggression. Aggr.

Norberg Background:, Many studies have found that earlier drinking initiation predicts higher risk of later alcohol and substance use problems, but the causal relationship between age of initiation and later risk of substance use disorder remains unknown. Method:, We use a "natural experiment" study design to compare the 12-month prevalence of Diagnostic and Statistical Manual, Fourth Edition, alcohol and substance use disorders among adult subjects exposed to different minimum legal drinking age laws minimum legal drinking age in the 1970s and 1980s. The sample pools 33,869 respondents born in the United States 1948 to 1970, drawn from 2 nationally representative cross-sectional surveys: the 1991 National Longitudinal Alcohol Epidemiological Survey (NLAES) and the 2001 National Epidemiological Study of Alcohol and Related Conditions. Analyses control for state and birth year fixed effects, age at assessment, alcohol taxes, and other demographic and social background factors. Results:, Adults who had been legally allowed to purchase alcohol before age 21 were more likely to meet criteria for an alcohol use disorder [odds ratio (OR) 1.31, 95% confidence intervals (95% CI) 1.15 to 1.46, p < 0.0001] or another drug use disorder (OR 1.70, 95% CI 1.19 to 2.44, p = 0.003) within the past-year, even among subjects in their 40s and 50s. There were no significant differences in effect estimates by respondent gender, black or Hispanic ethnicity, age, birth cohort, or self-reported age of initiation of regular drinking; furthermore, the effect estimates were little changed by inclusion of age of initiation as a potential mediating variable in the multiple regression models. Conclusion:, Exposure to a lower minimum legal purchase age was associated with a significantly higher risk of a past-year alcohol or other substance use disorder, even among respondents in their 40s or 50s. However, this association does not seem to be explained by age of initiation of drinking, per se. Instead, it seems plausible that frequency or intensity of drinking in late adolescence may have long-term effects on adult substance use patterns. [source] Trust in digital informationJOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 3 2008Kari Kelton Trust in information is developing into a vitally important topic as the Internet becomes increasingly ubiquitous within society. Although many discussions of trust in this environment focus on issues like security, technical reliability, or e-commerce, few address the problem of trust in the information obtained from the Internet. The authors assert that there is a strong need for theoretical and empirical research on trust within the field of information science. As an initial step, the present study develops a model of trust in digital information by integrating the research on trust from the behavioral and social sciences with the research on information quality and human, computer interaction. The model positions trust as a key mediating variable between information quality and information usage, with important consequences for both the producers and consumers of digital information. The authors close by outlining important directions for future research on trust in information science and technology. [source] Capability, Quality, and Performance of Offshore IS Vendors: A Theoretical Framework and Empirical InvestigationDECISION SCIENCES, Issue 2 2010Prashant C. Palvia ABSTRACT Information systems (IS) offshoring has become a widespread practice and a strategic sourcing choice for many firms. While much has been written by researchers about the factors that lead to successful offshoring arrangements from the client's viewpoint, the vendor's perspective has been largely scarce. The vendor perspective is equally important as offshore IS vendors need to make important decisions in terms of delivering operational and strategic performance and aligning their resources and processes in order to meet or exceed targeted outcomes. In this article, we propose and test a three-level capability,quality,performance (CQP) theoretical framework to understand vendor outcomes and their antecedents. The first level of the framework represents three vendor capabilities: relationship management, contract management, and information technology management. The second level has three mediating variables representing process quality: partnership, service, and deliverable quality. The third level has three dependent variables representing vendor outcomes: operational performance, strategic performance, and satisfaction. The model was tested with 188 vendor firms from India and China, the two most popular destinations for IS offshoring. Results support the CQP framework; vendor capabilities are significant predictors of intermediate quality measures, which in turn affect vendor outcomes. Implications of the study findings to both theory development and IS offshore vendor strategic decision making are discussed. [source] Early pubertal maturation in the prediction of early adult substance use: a prospective studyADDICTION, Issue 1 2009Mohammad R. Hayatbakhsh ABSTRACT Aims To examine whether self-reporting a later stage of pubertal development in early adolescence predicts young adults' use of illicit drugs. Design Population-based prospective birth cohort study. Setting Follow-up of a cohort of mothers and their children, recruited between 1981 and 1983. Participants Cohort of 2710 young adults who completed a self-report questionnaire about their use of cannabis and amphetamines at the 21-year follow-up. Measurements Young adults' use of cannabis and amphetamines were measured at the 21-year follow-up. Stage of pubertal development was assessed at the 14-year follow-up. Potential confounding and mediating variables were assessed between birth and when the child was 14 years. Findings Of 2710 young adults, 49.9% (47.3 females and 52.7% males) reported that they had used cannabis and 21.0% (18.9% females and 23.3% males) reported that they had used amphetamines and cannabis by 21 years. In multivariate analyses, adolescents with a later stage of puberty were more likely to use cannabis or amphetamines in young adulthood. This association was not confounded by mother's education or child's gender and age. Part of the relationship was explained by the higher frequency of child externalizing behaviour at 14 years. Conclusions The findings warrant further attention to puberty as a sensitive period in an individual's development. With regard to prevention, there is a need to understand more about the pathways between pubertal development, child behaviour problems and substance use. [source] Coping with job stress in industries: A cognitive approachHUMAN FACTORS AND ERGONOMICS IN MANUFACTURING & SERVICE INDUSTRIES, Issue 3 2001Sun-Kyu Lee This study examined the roles of the coping strategies used by individuals to cope with job stress. The coping strategy was formed throughout the cognitive appraisal of the stressful events. It was found that direct action coping strategy shows negative relations with job stressors, whereas there are positive relations between stressors and other coping strategies. This implies that direct action coping strategy is used to alleviate the job stress by affirmatively changing the deleterious effects of job stressors in the work environment, while other coping strategies led to the positive impact on job stress or negative impact on job performance. To secure the usability and applicability of the model in practice, more considerations in the future should be made on the mediating variables such as personality type and social support, which are possible variables impacting the selection of coping strategy. © 2001 John Wiley & Sons, Inc. [source] Investigating the relationship between past contraceptive behaviour, self-efficacy, and anticipated shame and guilt in sexual contexts among Norwegian adolescentsJOURNAL OF COMMUNITY & APPLIED SOCIAL PSYCHOLOGY, Issue 1 2007Bente Træen Abstract What are the relationships between self-efficacy when communicating to the partner about use of contraception, stopping undesired intercourse, and perceived self-conscious emotions in sexual contexts? How does past contraceptive behaviour influence perceived self-efficacy? These research questions were studied among 399 10th grade students with coital experience in the county Nordland in Norway. Two dimensions of perceived emotional responses were identified in a hypothetical situation related to communicating to the partner about use of contraception, namely Shame and Emotional intimacy. Two dimensions were also identified with regard to anticipated emotional responses in a hypothetical situation related to stopping undesired intercourse: Guilt and responsibility and Emotional intimacy. Most of the boys and girls reported that they would react with positive emotions in both hypothetical situations. Path models were constructed with the affective dimensions and self-esteem as mediating variables between past contraceptive behaviour and contextual self-efficacy. Past behaviour influenced communication self-efficacy indirectly via Shame, and Shame had a direct effect upon self-efficacy. Guilt and responsibility had a direct effect upon stop-self-efficacy.

[source] Relationship Marketing and Supplier Logistics Performance: An Extension of the Key Mediating Variables ModelJOURNAL OF SUPPLY CHAIN MANAGEMENT, Issue 4 2005Matthew Morris Summary Firms are increasingly relying on relational exchanges to govern buyer,supplier relationships. While the antecedents to these relationships have been studied extensively in the marketing channels and supply chain management literature, relatively little research has considered the performance outcomes of such exchanges. The current study contributes to this stream of research by extending Morgan and Hunt's key mediating variables (KMV) model to examine how the five key endogenous variables from the KMV model affect supplier logistics performance. The findings suggest that cooperation and uncertainty are significantly related to supplier logistics performance, while supplier acquiescence, functional conflict and propensity to leave the relationship have no significant impact. [source] Adherence to treatment in patients with psoriasisJOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 4 2006HL Richards Abstract Non-adherence to medication is a chronic problem that impacts on healthcare professionals and patients alike. In psoriasis, a condition that presents patients with frequent and disabling physical, psychological and social effects, studies consistently suggest that up to 40% of patients do not use their medication as directed. Thus it is probable that poor adherence contaminates the clinical picture of response effectiveness in everyday practice. This educational paper reviews research that investigates adherence to medication in patients with psoriasis. It provides an overview of contributing factors and mediating variables. It is proposed that three specific facets appear to optimize patient adherence: an effective doctor,patient relationship; optimism with the treatment prescribed; and a limited ,nuisance' value of treatment in terms of side-effects and hassle of use. Various strategies to address adherence are suggested and it is argued that in order to enhance our understanding of adherence in patients with psoriasis, there needs to be an increasing focus on patients' beliefs about their condition and its management. [source] Perceived ease of use in prior e-commerce experiences: A hierarchical model for its motivational antecedentsPSYCHOLOGY & MARKETING, Issue 9 2010Tao Sun This study develops and tests a theoretical model to evaluate the motivational factors behind perceived ease of use in prior e-commerce experiences. This hierarchical model includes need for arousal as the independent variable; general self-efficacy, technological innovativeness, and consumer self-determination as the mediating variables; and perceived ease of use in prior e-commerce experiences as the dependent variable. Tested by data generated from a survey of 290 consumers, the model yields satisfactory fit and contributes to the literature by adding more intrinsically motivational variables to predict perceived ease of use. Practical and academic implications are also discussed. © 2010 Wiley Periodicals, Inc. [source] The investigation of Chinese consumer values, consumption values, life satisfaction, and consumption behaviorsPSYCHOLOGY & MARKETING, Issue 7 2009Ge Xiao The primary objective of this study was to investigate how the changing value systems of modern Chinese consumers affect their consumption behaviors and life satisfaction through the mediating variables of consumption values. The results of the multivariate data analysis show that three out of four types of consumer values (i.e., functional, emotional, and social) were positively related to foreign brand purchasing. Among all accepted relationships, the one between collectivism and functional value was the highest, whereas the collectivism and epistemic value relationship was the lowest. Individualism and collectivism were both found to be positively related to foreign brand purchasing and life satisfaction. Compared to collectivists, individualists were less satisfied with their current lives, but they held a more favorable attitude toward foreign brands. © 2009 Wiley Periodicals, Inc. [source] A conceptual model of perceived customer value in e-commerce: A preliminary investigationPSYCHOLOGY & MARKETING, Issue 4 2003Zhan Chen This article presents an exploratory study of a conceptual model of perceived customer value in a business-to-consumer e-commerce setting. Key precursors of perceived customer value included in the model are valence of on-line shopping experience, perceived product quality, perceived risk, and product price. Relationships among these variables (as well as mediating variables) and their relationship to on-line shoppers' value perceptions are explored. The theoretical framework proposed in this work expands on previous efforts on perceived customer value by including new variables relevant to an e-commerce setting and by integrating several key variables into one model. The preliminary findings lead to several implications. © 2003 Wiley Periodicals, Inc. [source] Annotation: Childhood Bereavement Following Parental DeathTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 7 2000Linda Dowdney Psychological outcomes in children who have experienced the death of a parent are heterogeneous. One child in five is likely to develop psychiatric disorder. In the year following bereavement, children commonly display grief, distress, and dysphoria. Nonspecific emotional and behavioural difficulties among children are often reported by surviving parents and the bereaved children themselves. The highest rates of reported difficulties are found in boys. This review identifies the moderating and mediating variables that lead to some children being more vulnerable to disturbance than others following parental death. Limitations and gaps in the recent bereavement literature are identified. Theoretical and methodological advances that are necessary for a coherent account of childhood bereavement are outlined. [source] Closeness in relationships as a mediator between sexual abuse in childhood or adolescence and psychopathological outcome in adulthoodCLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 3 2010Nevena Dimitrova Abstract The risk of adverse psychological outcomes in adult victims of childhood and adolescent sexual abuse (CSA) has been documented; however, research on possible mediating variables is still required, namely with a clinical perspective. The attachment literature suggests that secure interpersonal relationships may represent such a variable. Twenty-eight women who had experienced episodes of CSA, and 16 control women, were interviewed using Bremner's Early Trauma Inventory and the DSM-IV Global Assessment of Functioning; they also responded to Collins' Relationship Scales Questionnaire, evaluating adult attachment representations in terms of Closeness, Dependence and Anxiety. Subjects with an experience of severe abuse reported significantly more interpersonal distance in relationships (low index of Closeness) than other subjects. The index of psychopathological functioning was correlated with both the severity of abuse and attachment (low index of Closeness). Regression analysis on the sample of abused women revealed that attachment predicted psychopathology when abuse was controlled for, whereas abuse did not predict psychopathology when attachment was controlled for. Therefore, preserving a capacity for closeness with attachment figures in adulthood appears to mediate the consequences of CSA on subsequent psychopathological outcome. Copyright © 2009 John Wiley & Sons, Ltd. Key Practitioner Message: , The way CSA victims deal with closeness and intimacy in relationships contributes to the quality of psychological outcome in adulthood. , Treatment strategies for CSA victims should emphasize the enhancement of interpersonal experiences and the strengthening of the subject's sense of closeness to others, intimacy in relationships, and confidence in others. [source] Child Sexual Abuse and Sexual RevictimizationCLINICAL PSYCHOLOGY: SCIENCE AND PRACTICE, Issue 2 2002Catalina M. Arata Research identifying rates and effects of adult/adolescent sexual revictimization among child sexual abuse victims was reviewed. Approximately one-third of child sexual abuse victims report experiencing repeated victimization. Child sexual abuse victims have a 2 to 3 times greater risk of adult revictimization than women without a history of child sexual abuse. Physical contact in abuse and revictimization in adolescence were found to lead to the greatest risk of revictimization. Repeated victims had more symptoms of Post Traumatic Stress Disorder (PTSD) and dissociation than women with a history of child sexual abuse alone. Theories of revictimization and mediating variables were also reviewed. Clearer definitions of repeated victimization are needed and future research should include studies that follow child sexual abuse victims prospectively. [source] | ||||||||||||||||
