The scale of adolescent inactivity gives the question real urgency. The World Health Organization recommends that young people aged 11 to 17 accumulate at least 60 minutes of moderate-to-vigorous physical activity daily, yet roughly 81 percent of adolescents worldwide fall short of that target. In China the picture is starker: national surveillance data cited in the study indicate that only 22.6 percent of Chinese adolescents meet recommended activity levels, with a marked decline during the middle school years. Because parental influence is among the most proximal determinants of youth activity, understanding precisely how parental attitudes become behavior matters for public health.

Most prior research has focused on what parents do, such as providing transport, equipment, or encouragement. This study instead examined what parents expect. Drawing on the Expectancy-Value Model, which holds that parents transmit beliefs about their children’s competence and the value of activities, Feng proposed that expectations function as a socialization signal that adolescents internalize. But expectations alone, the theory suggests, are inert until they pass through the adolescent’s own motivational machinery. That machinery, according to Self-Determination Theory, depends on the satisfaction of three basic psychological needs: autonomy, the sense of volitional engagement; competence, the feeling of being effective; and relatedness, the experience of social connection.

The theoretical sequence is elegant. Parents who communicate expectations in a need-supportive way, acknowledging the adolescent’s perspective, offering meaningful rationales, and providing choices rather than pressure, should foster need satisfaction in the exercise domain. That need satisfaction should then catalyze autonomous motivation, meaning exercise done out of genuine interest or personal valuation rather than guilt or external demand. Autonomous motivation, in turn, is the form of motivation most reliably linked to persistent behavior. The study tested whether this chain, from parental expectation to need satisfaction to autonomous motivation to actual exercise, holds up statistically.

Participants completed validated instruments covering all four constructs. Perceived parental expectations were measured with a six-item scale adapted from Fredricks and Eccles and Trost and colleagues, translated into Chinese through back-translation and showing good internal consistency. Basic psychological need satisfaction was assessed with a 12-item adapted scale covering autonomy, competence, and relatedness, combined into a composite because the three subscales were strongly intercorrelated. Exercise motivation was captured by the Behavioral Regulation in Exercise Questionnaire-2, from which a Relative Autonomy Index was computed, weighting each regulatory style along a continuum from controlled to autonomous. Exercise behavior itself was measured with the International Physical Activity Questionnaire Short Form, log-transformed to handle skewness.

The results supported the chain. Parental expectations predicted exercise behavior directly, with a standardized coefficient of 0.11, and indirectly, with a total indirect effect of 0.13. The sequential pathway through need satisfaction and then autonomous motivation was significant on its own, contributing a standardized indirect effect of 0.04. Taken together, the indirect pathways accounted for 52.6 percent of the total association between parental expectations and exercise behavior, with the full chain-specific route accounting for 15.7 percent. Bootstrap confidence intervals based on 5,000 resamples excluded zero for every pathway tested, and the model explained 17 percent of the variance in exercise behavior overall.

The most striking finding concerned gender. Females in the sample actually reported higher perceived parental expectations and higher autonomous motivation than males, yet the motivational chain linking expectations to behavior was roughly three times stronger among males. The chain-mediated indirect effect was 0.06 for males against 0.02 for females, a between-group difference of 0.04 with a bootstrap confidence interval excluding zero. Two structural paths drove this asymmetry: the link from need satisfaction to autonomous motivation and the link from autonomous motivation to behavior were both significantly stronger for boys. The model also explained more than twice as much variance in exercise behavior for males as for females.

The authors offer a gender-role interpretation. Because exercise is normatively more congruent with the male gender role, boys may have developed stronger cognitive-behavioral links between motivation and action. For girls, competing pressures, perceived barriers such as self-consciousness or safety concerns, body image worries, and academic demands may attenuate the translation of motivation into movement. The study is careful to note that these candidate mechanisms were not directly measured and remain hypotheses for future work. The practical implication, however, is that one-size-fits-all parental messaging is unlikely to succeed, and interventions for girls may need to address barriers and peer support alongside expectations.

The study’s limitations are candidly acknowledged. All data are cross-sectional and self-reported from a single assessment occasion, so the findings represent associations compatible with the proposed theoretical sequence rather than demonstrated causal effects. Because the structural sub-model is just-identified, statistically equivalent orderings of the mediators cannot be ruled out, and longitudinal designs with multiple waves are needed to establish temporal precedence. The sample came from a single city in central China, family socioeconomic status was only roughly proxied, and the three psychological needs were combined into one composite score, potentially masking need-specific processes.

Even with those caveats, the work adds a mechanistic layer to a well-established correlation. The message for parents is not simply to expect more, but to communicate expectations in ways that satisfy adolescents’ needs for autonomy, competence, and connection, thereby letting internal motivation do the work that pressure cannot. For female adolescents in particular, the findings suggest that heightened expectations alone may be insufficient, and that fostering need satisfaction and autonomous motivation may be essential for sustained engagement. As physical inactivity continues to rank among the most tractable modifiable health risks of adolescence, unpacking the family-to-behavior pipeline one psychological link at a time is a step toward interventions that actually move the needle.
