a meta analysis of self determination theory informed intervention studies in the health domain effects on motivation health behavior physical and psychological health
Health Psychology Review, 2020Co-Authors: Nikos Ntoumanis, Andrew Prestwich, Eleanor Quested, Jennie E Hancox, Cecilie Thogersenntoumani, Edward L Deci, Richard M Ryan, Chris Lonsdale, Geoffrey C WilliamsAbstract:There are no literature reviews that have examined the impact of health-domain interventions, informed by self-determination theory (SDT), on SDT Constructs and health indices. Our aim was to meta-analyse such interventions in the health promotion and disease management literatures. Studies were eligible if they used an experimental design, tested an intervention that was based on SDT, measured at least one SDT-based Motivational Construct, and at least one indicator of health behaviour, physical health, or psychological health. Seventy-three studies met these criteria and provided sufficient data for the purposes of the review. A random-effects meta-analytic model showed that SDT-based interventions produced small-to-medium changes in most SDT Constructs at the end of the intervention period, and in health behaviours at the end of the intervention period and at the follow-up. Small positive changes in physical and psychological health outcomes were also observed at the end of the interventions. Increases in need support and autonomous motivation (but not controlled motivation or amotivation) were associated with positive changes in health behaviour. In conclusion, SDT-informed interventions positively affect indices of health; these effects are modest, heterogeneous, and partly due to increases in self-determined motivation and support from social agents.

disentangling motivation intention and planning in the physical activity domain
Psychology of Sport and Exercise, 2006Co-Authors: Ryan E Rhodes, Chris M Blanchard, Deborah Hunt Matheson, James D CobleAbstract:Abstract Objectives Planning/implementation intentions has received support as a post-Motivational Construct across many behavioural domains but limited research has integrated the Construct into a theoretical structure. The theory of planned behaviour (TPB) seems most suited to integrate implementation intentions into its structure because it lacks a planning Construct. Still, semantic ambiguities between intention and planning may make the measurement domains of these proposed Constructs similar even if the two Constructs are conceptually different. The purpose of this study was (1) to evaluate the discriminant validity of motivation items (e.g. exert effort, try hard), intention items (e.g. intend, plan), and implementation intention/planning items (e.g. specific plans), and (2) to then integrate distinct motivation and planning Constructs into the TPB model. Design The study followed a prospective survey design where TPB and related variables were measured at baseline and physical activity was measured two weeks later. Methods Participants were 230 undergraduate students (70% female) who completed measures of the TPB and self-reported physical activity. Results Structural equation modelling showed that motivation and planning items possessed discriminant validity ( p p >0.05). Still, planning did not augment motivation-physical activity relations ( p >0.05). Conclusions Intention items appear to straddle the measurement domains of planning and motivation. Careful item choices should be made when researchers wish to incorporate motivation and planning Constructs in the same model. Planning did not add to the TPB model when predicting physical activity. The discrepancy between these results and prior research is discussed in terms of the differences between experimental and survey designs, and behaviour adoption versus maintenance.

an analysis of hope as a psychological strength
Journal of School Psychology, 2006Co-Authors: Michael F Valle, Scott E Huebner, Shannon M SuldoAbstract:Abstract Psychologists have placed an increased emphasis on identifying psychological strengths that foster healthy development. Hope, as operationalized in Snyder's hope theory Snyder, C. R., Hoza, B., Pelham, W. E., Rapoff, M., Ware, L., & Danovsky, M., et al. (1997). The development and validation of the children’s hope scale. Journal of Pediatric Psychology , 22, 399–421], is one such cognitive-Motivational Construct that has received recent attention as a potential psychological strength that may serve as a protective factor for adolescents in the face of adverse life events. This longitudinal study, involving middle and high school students, provided evidence of (1) stability of hope reports of adolescents over a 1-year period, (2) predictive validity of adolescent hope reports, and (3) hope's functional role as a moderator in the relationship between stressful life events and adolescent well-being. Taken together, the results provide support for consideration of hope as a key psychological strength in youth. The findings are consistent with theories of motivation in which individual differences in hopeful thinking are conceptualized to play a functional role in linking life events and psychological well being.

Role of food neophilia in food market tourists’ Motivational Construct: The case of La Boqueria in Barcelona, Spain
Journal of Travel & Tourism Marketing, 2016Co-Authors: Darko Dimitrovski, Montserrat Crespi-vallbonaAbstract:ABSTRACTIn this paper we advocate the study of local food markets to explore fundamental issues about the relationship between these urban tourist attractions and visitors’ motivation and satisfaction. Based on a survey in La Boqueria Market in Barcelona, Spain, we test the direct effect of escape from routine, cultural experience, prestige, and food market involvement on satisfaction, and also the moderator role of food neophilia in this relationship. We conclude that tourists visiting food markets are motivated mainly by cultural experience and interaction with local producers, while food neophilia plays a significant moderator role.
