Purpose: Based on the self-determination theory and the model of action phases, the present study aims to provide insight into motivational factors that are important for training initiation. It investigates the relations between three types of motivation (intrinsic, extrinsic and amotivation) and training initiation: intention to initiate new training and plan formulation. Design/methodology/approach: Data were collected from 155 employees using the Motivation for Training Initiation Scale and the Training Intention and Training Planning Scales. Findings: The results of hierarchical regression analyses show that intrinsic and extrinsic motivation are positively, while amotivation is negatively, related to intention to start new training. Intrinsic motivation is a significant predictor of training plan formulation. The stronger is the intention, the more precise are plans to undertake training. Research limitations/implications: The cross-sectional study design limits causal conclusions concerning actual training action. This, therefore, encourages the validation of study hypotheses in a longitudinal manner. Practical implications: The results offer suggestions on how to foster training initiation taking into account types of motivation. Originality/value: The study for the first time combines the model of action phases with the self-determination theory.
