There were no effects of the planning constructs. Attitudes, subjective norm, and, indirectly, autonomous motivation to reduce sugar consumption predicted intentions. A structural equation model revealed that intentions, implicit attitudes, and, indirectly, autonomous motivation to reduce sugar consumption had small, significant effects on sugar consumption. Self-reported sugar consumption was measured two weeks later.

Using a prospective design, university students (N = 90) completed initial measures of the reflective (autonomous and controlled motivation, intentions, attitudes, subjective norm, perceived behavioral control), impulsive (implicit attitudes), volitional (action and coping planning), and behavioral (past sugar consumption) components of the proposed model. We tested the efficacy of an integrated dual-process, dual-phase model derived from multiple theories to predict sugar consumption.

Identifying the modifiable social cognitive and motivational constructs that predict sugar consumption is important to inform behavioral interventions aimed at reducing sugar intake. 5 School of Psychology and Speech Pathology, Health Psychology and Behavioural Medicine Research Group, Curtin University, Perth, Western Australia, Australia School of Applied Psychology and Menzies Health Institute Queensland, Griffith University, Brisbane, Queensland, Australia.Įxcess consumption of added dietary sugars is related to multiple metabolic problems and adverse health conditions.4 School of Public Health, University of Hong Kong, Hong Kong.3 School of Applied Psychology and Menzies Health Institute Queensland, Griffith University, Brisbane, Queensland, Australia.Electronic address: 2 School of Psychology and Speech Pathology, Health Psychology and Behavioural Medicine Research Group, Curtin University, Perth, Western Australia, Australia Faculty of Health, Medicine, and Life Sciences, Maastricht University, Maastricht, The Netherlands. 1 School of Psychology and Speech Pathology, Health Psychology and Behavioural Medicine Research Group, Curtin University, Perth, Western Australia, Australia School of Applied Psychology and Menzies Health Institute Queensland, Griffith University, Brisbane, Queensland, Australia Faculty of Sport and Health Sciences, University of Jyväskylä, Jyväskylä, Finland Department of Physical Education, Hong Kong Baptist University, Hong Kong.
