Measures satisfaction of the three universal psychological needs posited by Self-Determination Theory (SDT): Autonomy (feeling that one's actions are self-chosen and volitional), Competence (feeling effective and capable in one's activities), and Relatedness (feeling connected to and cared for by important others). Basic need satisfaction is SDT's central explanatory mechanism for psychological wellbeing, intrinsic motivation, and flourishing — when these three needs are satisfied, people function optimally and experience vitality and wellbeing; when thwarted, they experience ill-being and controlled motivation. The BPNS is adapted from Ilardi, Leone, Kasser & Ryan (1993) for general life contexts and is the most widely used general-context needs satisfaction scale in SDT research. Foundational to research on employee wellbeing, consumer autonomy, healthcare self-management, and educational motivation.
Likert (1–7, not at all true to very true)
Three subscale scores. Autonomy satisfaction is the most potent predictor of psychological wellbeing and autonomous motivation; Relatedness is the strongest predictor of social functioning. The Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS; Chen et al., 2015, Journal of Research in Personality) is the most current psychometrically rigorous version, adding need frustration subscales alongside satisfaction. The BPNS has been adapted for dozens of life domains including consumer choice, healthcare, education, and sport.
