Dietary Planning as a Mediator of the Intention,Behavior Relation: An Experimental-Causal-Chain Design

APPLIED PSYCHOLOGY, Issue 2008
Tabea Reuter
Health behavior change is seen as a self-regulatory process that consists of a motivation phase of goal setting and a volition phase of goal pursuit. Previous studies suggest that the intention,behavior association is mediated by planning. However, evidence is based on observational studies rather than on experimental designs. To validate the causal assumptions, an experimental-causal-chain design was employed. Study 1 (n= 145) examined whether changing dietary intentions by a motivational intervention engenders changes in planning activities 1 month later. Study 2 (n= 115) examined, in a different sample, whether a volitional planning intervention engenders changes in dietary behavior 1 month later. In both studies, repeated measures ANOVAs revealed a significant Time × Condition interaction. Changes in intention mediated the effects of the motivational intervention on planning activities (Study 1). Changes in planning mediated the effect of a planning intervention on dietary behavior (Study 2). Previous observational findings on planning as a mediator in the intention,behavior association were supported by the two experiments. The findings might help to identify points of intervention in the process underlying health behavior change. Le changement de comportement au plan de la santé est considéré comme un processus d'auto-régulation qui se compose d'une phase de motivation (fixation des buts) et d'une phase de volition (poursuite des buts). Des études précédentes suggèrent que le passage de l'intention au comportement est médiatisé par la planification. Ces résultats sont obtenus par voie d'observations plutôt que par expérimentations. Pour valider les hypothèses de causalité, un modèle de chaîne-causale-expérimentale a été employé. L'étude 1 examine si, en changeant les intentions alimentaires par une intervention motivationnelle, on obtient des changements dans la planification des activités un mois après (n= 145). L'étude 2 examine, sur un échantillon différent, si la planification d'une intervention engendre des changements du comportement alimentaire un mois plus tard (n= 115). Pour ces deux études, des ANOVA à mesures répétées révèlent une interaction significative entre le temps et la condition étudiée. Les changements de l'intention influencent les effets de l'intervention motivationnelle sur la planification des activités (étude 1). Les changements de la planification influencent les effets de l'intervention de la volition sur le comportement alimentaire (Etude 2). Les résultats obtenus par observation sur la planification comme lien entre l'intention et le comportement sont confirmés par les expérimentations. Les résultats peuvent permettre d'identifier les modalités d'interventions relatives au processus sous-tendant le changement du comportement de santé. [source]

Self-Efficacy and Planning Predict Dietary Behaviors in Costa Rican and South Korean Women: Two Moderated Mediation Analyses

APPLIED PSYCHOLOGY: HEALTH AND WELL-BEING, Issue 1 2009
Benicio Gutiérrez-Doña
Dietary planning is supposed to mediate between intentions and dietary behaviors. However, if a person lacks self-efficacy, this mediation might fail. A cross-sectional study in Costa Rica and a longitudinal study in South Korea were designed to examine the moderating role of self-efficacy in the intention,planning,behavior relationship. Intentions, planning, self-efficacy, dietary behaviors, and baseline diet were assessed. Study 1 included 245 women; Study 2 included 358 women. Moderated mediation models were specified in which planning served as a mediator between intentions and behavior. Self-efficacy was specified as a moderator of the intention,planning,behavior relationship. Intentions were translated into dietary behavior by planning. However, levels of self-efficacy moderated this mediation process: The strength of the mediated effect increased along with levels of self-efficacy, even when accounting for baseline dietary behaviors. For planning to mediate the intention,behavior relation, people must harbor sufficient levels of self-efficacy. If they lack self-efficacy, either intentions are not well translated into planning, or planning is not well translated into behavior. Further research needs to clarify under which circumstances the moderator effect of self-efficacy operates in the first phase or the second phase of the mediation process. [source]

Imaging the developing brain with fMRI

DEVELOPMENTAL DISABILITIES RESEARCH REVIEW, Issue 3 2003
M.C. Davidson
Abstract Advancements in magnetic imaging techniques have revolutionized our ability to study the developing human brain in vivo. The ability to noninvasively image both anatomy and function in healthy volunteers, including young children, has already enhanced our understanding of brain and behavior relations. The application of these techniques to developmental research offers the opportunity to further explore these relationships and allows us to ask questions about where, when and how cognitive abilities develop in relation to changes in underlying brain systems. It is also possible to explore the contributions of maturation versus learning in the development of these abilities through cross-sectional and longitudinal research involving training and intervention procedures. Current imaging methodologies, in conjunction with new and rapidly evolving techniques, hold the promise of even greater insights into developmental issues in the near future. These methodologies and their application to development and learning are discussed in the current paper. MRDD Research Reviews 2003;9:161,167. © 2003 Wiley-Liss, Inc. [source]

Practitioner Review: Computerized assessment of neuropsychological function in children: clinical and research applications of the Cambridge Neuropsychological Testing Automated Battery (CANTAB)

THE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 5 2003
Monica Luciana
Background: Computers have been used for a number of years in neuropsychological assessment to facilitate the scoring, interpretation, and administration of a variety of commonly used tests. There has been recent interest in applying computerized technology to pediatric neuropsychological assessment, which poses unique demands based on the need to interpret performance relative to the child's developmental level. Findings: However, pediatric neuropsychologists have tended to implement computers in the scoring, but not administration, of tests. This trend is changing based on the work of experimental neuropsychologists who frequently combine data obtained from test batteries with lesion or neuroimaging data allowing descriptions of brain,behavior relations to be made with increasing confidence. One such battery is the Cambridge Neuropsychological Testing Automated Battery (CANTAB), and current studies in which the CANTAB has been used to measure executive functions in children are reviewed. Conclusions: Computerized batteries of this type can record aspects of performance that are difficult for psychometrists to achieve, and these may reflect activity in developing neural networks with more sensitivity than can be achieved with traditional tests. However, before computerized test administration becomes a routine part of pediatric neuropsychological assessment, several obstacles must be overcome. Despite these limitations, it is concluded that computerized assessment can improve the field by facilitating the collection of normative and clinical data. [source]
