Abstract

The current study aimed to assess the components of the intervention program “Aquatic”, targeted at the reduction of bottled water use in adolescence. The Comprehensive Action Determination Model was chosen as a theory of change for the development and evaluation of pro-environmental behavior intervention. We examined the impact of five experimental intervention factors (water bottles, promo video, prompts, goal setting, and feedback) on eight intervention program outcomes: Perceived behavioral control, Social norm, Habit, Awareness of need, Awareness of consequence, Personal norm, Intention, and Behavior. The study sample consisted of 419 adolescents (52.8% girls, Mage = 15.21, SDage = .64) from Lithuania. A factorial experimental study design was used, and a Latent change modeling approach was applied for the evaluation of individual and combined effects of intervention components. Promo video, Prompts, and Goal setting had a positive effect on Awareness of consequence, Social norm, and Awareness of need, respectively. Receiving a Water bottle in combination with the Promo video had a positive effect on Perceived behavioral control and in combination with Prompts as well as Goals – on Awareness of need. Water bottles, Promo-video, Prompts, and Goals, but not Feedback, had value in the promotion of targeted pro-environmental outcomes.
