Disentangling social selection and social influence effects on adolescent smoking: the importance of reciprocity in friendships

ADDICTION, Issue 9 2007
Liesbeth Mercken
ABSTRACT Aims The goal of this study was to examine social selection and social influence within reciprocal and non-reciprocal friendships, and the role of parents and siblings, as factors explaining similarity of smoking behaviour among adolescent friends. A new social selection,social influence model is proposed. Design Longitudinal design with two measurements. Setting Data were gathered among Dutch high school students in the control group of the European Smoking prevention Framework Approach (ESFA) study. Participants The sample consisted of 1886 adolescents with a mean age of 12.7 years. Measurements The main outcome measures were the smoking behaviours of the respondents, best friends, parents and siblings. We tested the social selection,social influence model with structural equation modelling techniques. Findings Social selection and social influence both played an important role in explaining similarity of smoking behaviour among friends. Within non-reciprocal friendships, only social selection explained similarity of smoking behaviour, whereas within reciprocal friendships, social influence and possibly also social selection explained similarity of smoking behaviour. Sibling smoking behaviour was a more important predictor of adolescent smoking behaviour than parental smoking behaviour. Conclusions Social selection and social influence both promote similarity of smoking behaviour, and the impact of each process differs with the degree of reciprocity of friendships. These insights may contribute to further refinement of smoking prevention strategies. [source]

Exploring the relationship between consumer knowledge and purchase behaviour of value-based labels

INTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 5 2008
Morven G. McEachern
Abstract Despite an increasing market presence, little research has been conducted regarding consumer-purchase behaviour of food products bearing ,value-based' labels. Moreover, as the effectiveness of these labelling formats is dependent upon consumer's knowledge of their existence, this paper aims to explore the relationship between knowledge, openness to experience (i.e. validated personality trait related to intellectual capability) and purchase behaviour upon consumer behaviour in this context. Using structural equation modelling techniques, causal influences on purchases of fresh meat bearing ,value-based' labels are identified and three multi-attribute attitude models are proposed. The paper concludes that these labels are of value to consumers and that product knowledge plays a significant role in aiding purchase decisions. Consequently, marketing communication implications arising from the proposed multi-attribute attitude models are discussed. [source]

Organizational Justice and Individuals' Withdrawal: Unlocking the Influence of Emotional Exhaustion

JOURNAL OF MANAGEMENT STUDIES, Issue 3 2010
Michael S. Cole
abstract This study examined the relationships between organizational justice and withdrawal outcomes and whether emotional exhaustion was a mediator of these linkages. Data were obtained from 869 military personnel and civil servants; using structural equation modelling techniques, we examined an integrative model that combines justice and stress research. Our findings suggest that individuals' justice perceptions are related to their psychological health. As predicted, emotional exhaustion mediated the linkages between distributive and interpersonal (but not procedural and informational) justice and individuals' withdrawal reactions. Results showed that distributive and interpersonal justice negatively related to emotional exhaustion and emotional exhaustion negatively related to organizational commitment which, in turn, negatively influenced turnover intentions. These findings were observed even when controlling for the presence of contingent-reward behaviours provided by supervisors and individuals' psychological empowerment. [source]

The impact of case specificity and generalisable skills on clinical performance: a correlated traits,correlated methods approach

MEDICAL EDUCATION, Issue 6 2008
Paul F Wimmers
Context, The finding of case or content specificity in medical problem solving moved the focus of research away from generalisable skills towards the importance of content knowledge. However, controversy about the content dependency of clinical performance and the generalisability of skills remains. Objectives, This study aimed to explore the relative impact of both perspectives (case specificity and generalisable skills) on different components (history taking, physical examination, communication) of clinical performance within and across cases. Methods, Data from a clinical performance examination (CPX) taken by 350 Year 3 students were used in a correlated traits,correlated methods (CTCM) approach using confirmatory factor analysis, whereby ,traits' refers to generalisable skills and ,methods' to individual cases. The baseline CTCM model was analysed and compared with four nested models using structural equation modelling techniques. The CPX consisted of three skills components and five cases. Results, Comparison of the four different models with the least-restricted baseline CTCM model revealed that a model with uncorrelated generalisable skills factors and correlated case-specific knowledge factors represented the data best. The generalisable processes found in history taking, physical examination and communication were responsible for half the explained variance, in comparison with the variance related to case specificity. Conclusions, Pure knowledge-based and pure skill-based perspectives on clinical performance both seem too one-dimensional and new evidence supports the idea that a substantial amount of variance contributes to both aspects of performance. It could be concluded that generalisable skills and specialised knowledge go hand in hand: both are essential aspects of clinical performance. [source]
