I-Change Model

    The Integrated Model for explaining motivational and behavioral change, or the I-CHANGE Model, is derived from the Attitude – Social influence – self-Efficacy Model (De Vries et al., 1988; De Vries & Mudde, 1998), that can be considered as an integration of ideas of Ajzen’s Theory of Planned Behavior, Bandura’s Social Cognitive Theory, Prochaska’s Transtheoretical Model, the Health Belief Model, and goal setting theories.

    Previous versions of this model (referred to as the ASE-model) have been used to explain a variety of types of health behaviour.

    The I-Change Model states that covert and overt behaviors are determined by a person’s motivation or intention to carry out a particular type of behavior.

    Behavior is the result of a person’s intentions and abilities. Intentions can range from not contemplating behavioral change to contemplating to change the behavior very rapidly, e.g. within a month.

    A person’s abilities, such as being able to prepare and execute specific plans to reach the goal behaviour (e.g. implementation intentions [30]) as well as actual behavioural skills, will increase the likelihood that intentions will be transferred into actions, while barriers can lower these chances.

    A person’s motivation is determined by three factors: attitudes, social influences, and self-efficacy expectations.

    A person’s attitude consists of the perceived cognitive and emotional advantages and disadvantages of the behavior.

    Social influences consist of the perception of others carrying out this type of behavior (social modeling), the norms that people have with respect to these behaviors (social norms) and the support that they encounter from others in carrying out a particular type of behavir.

    Self-efficacy refers to a person’s perception of his capability to carry out the type of behavior. Recent studies showed that different types of self-efficacy may exist, such as social-, stress-, skills- and routine self-efficacy.

    The I-Change Model assumes these motivational factors are determined by various distal factors such as awareness factors (e.g. knowledge, risk perceptions and cues to action), predisposing factors such as behavioral factors (e.g. life styles), psychological factors (e.g. personality), biological factors (e.g. gender, genetic predisposition), social and cultural factors (e.g. the price of cigarettes, policies), and information factors (the quality of messages, channels and sources used).

    As you can see, you can use two ways to present the I-Change Model as can be seen from the figures. In the version 2.0 the presentation is focusing more on the three phases of behavior change.
