    Abstract

    A systematic review and meta-analysis was conducted of the techniques
    used to promote psychological need satisfaction and motivation within
    health interventions based on self-determination theory (SDT; Ryan &
    Deci, 2017. Self-determination theory: Basic psychological needs in motivation, development, and wellness.
    New York, NY: Guilford Press). Eight databases were searched from 1970
    to 2017. Studies including a control group and reporting pre- and
    post-intervention ratings of SDT-related psychosocial mediators (namely
    perceived autonomy support, need satisfaction and motivation) with
    children or adults were included. Risk of bias was assessed using items
    from the Cochrane risk of bias tool. 2496 articles were identified of
    which 74 met inclusion criteria; 80% were RCTs or cluster RCTs.
    Techniques to promote need supportive environments were coded according
    to two established taxonomies (BCTv1 and MIT), and 21 SDT-specific
    techniques, and grouped into 18 SDT based strategies. Weighted mean
    effect sizes were computed using a random effects model; perceived
    autonomy support g = 0.84, autonomy g = 0.81, competence g = 0.63, relatedness g = 0.28, and motivation g = 0.41. One-to-one interventions resulted in greater competence satisfaction than group-based (g = 0.96 vs. 0.28), and competence satisfaction was greater for adults (g = 0.95) than children (g = 0.11).
    Meta-regression analysis showed that individual strategies had limited
    independent impact on outcomes, endorsing the suggestion that a need
    supportive environment requires the combination of multiple co-acting
    techniques.
