Chan DK, Lonsdale C, Ho PY, Yung PS, Chan KM. Patient motivation and adherence to postsurgery rehabilitation exercise recommendations: the influence of physiotherapists' autonomy-supportive behaviors.

OBJECTIVE

To investigate the impact of physiotherapists' autonomy-supportive behaviors on patients' motivation and rehabilitation adherence after anterior cruciate ligament (ACL) reconstruction surgery.

DESIGN

Retrospective study.

SETTING

Outpatient orthopedic clinic of a university medical center.

PARTICIPANTS

Postsurgery ACL reconstruction patients (N=115; minimum postsurgery interval, 6mo; mean +/- SD postsurgery interval, 1.77+/-0.8y).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Questionnaires measuring autonomy support from physiotherapists (Health Care Climate Questionnaire), treatment motivation (Treatment Self-Regulation Questionnaire), and rehabilitation adherence (adapted from the Sport Injury Rehabilitation Adherence Scale and the Patient Self-Report Scales of Their Home-Based Rehabilitation Adherence).

RESULTS

Structural equation modeling analyses revealed that patients' treatment motivation mediated the relationship between physiotherapists' autonomy-supportive behaviors and rehabilitation adherence. Autonomy-supportive behavior positively predicted autonomous treatment motivation (beta=.22, P<.05). Rehabilitation adherence (R(2)=.28) was predicted positively by autonomous motivation (beta=.64, P<.05) and negatively predicted by controlled motivation (beta=-.28, P<.05).

CONCLUSIONS

These preliminary findings are promising and provide an empirical basis for further research to test the efficacy of autonomy support training designed to increase patients' rehabilitation adherence.
