What are the 3 SDT constructs?

What are the 3 SDT constructs?

• A. Attitude, subjective norms and perceived behavioural control.
• B. Perceived susceptibility, severity and barriers.
• C. Competence, autonomy and relatedness.
• D. Pros and cons of behaviour change.

Answer: (C)

Self-Determination Theory centers on three basic psychological needs that drive motivation: autonomy, competence, and relatedness. Autonomy is the sense of choice and volition in what you do; autonomy support helps people feel they are in control of their actions. Competence is feeling capable and effective, confidently meeting challenges. Relatedness is feeling connected and cared for by others. When these needs are satisfied, people are more intrinsically motivated to engage in healthy behaviors because the action aligns with their internal values and sense of self, not just external pressure. The option that lists competence, autonomy, and relatedness is the one that matches SDT. The other groups reflect constructs from different theories—for example, attitudes, norms, and perceived control come from the Theory of Planned Behavior; perceived susceptibility, severity, and barriers come from the Health Belief Model; and discussing the pros and cons of behavior change aligns with decisional balance from other behavior-change frameworks.
