Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized controlled trial for which the primary objective is to evaluate the effects of an online training program on physiotherapist's self-reported confidence in knowledge about weight management for people with osteoarthritis. 80 physiotherapists will be recruited into the study and randomized to one of two arms a) online training program (access to training program for 6 weeks) or b) control group (no access to online training program during the study). Questionnaires will be completed by all participants at baseline, and again at the end of the 6 week intervention period. A biostatistician will analyse blinded, de-identified data.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Centre for Health Exercise and Sports Medicine at the University of Melbourne have developed a 6-module online training program designed to up-skill physiotherapists in weight management for osteoarthritis patients. This is a randomised controlled trial evaluating the effectiveness of the training program on physiotherapist's confidence in weight management for osteoarthritis patients. After providing informed consent and baseline data, physiotherapists will be randomized to either a) an online training program or b) control group. Those randomized to the online training group will be provided access to the a 6-module weight management training program and have six weeks to complete all the modules. Those randomized to the control group will receive no intervention. At baseline and six weeks, primary and secondary outcome measures will be completed in both groups.

The research question is: What are the effects of an online training program designed to up-skill physiotherapists in weight management for people with osteoarthritis? The primary objective is to evaluate the effects of an online training program on physiotherapist's self-reported confidence in knowledge about weight management for people with osteoarthritis.

80 participants will be recruited and randomization into the two study groups. To detect an effect size of 0.8 with 80% power and two sided significance level of 5%, 26 participants are required per group. Assuming a 35% loss to follow up, this will increase the same size to 40 per group (80 in total). The study will be conducted through The University of Melbourne. Participants will be able to access the training remotely in their own time and access all outcome measures online.

A biostatistician will analyse blinded, de-identified data. Analyses will be conducted with participants in assigned groups, with multiple imputation to account for missing data if required. Changes in self-reported confidence scores (primary outcome) will be compared between groups at 6 weeks using linear regression (with group as a factor) adjusting for baseline scores and the stratifying variables. Similar analyses will be conducted for secondary outcomes measured at baseline and 6 weeks. Process measures will be described in terms of mean (SD)/median (IQ range) or number (frequency). Standard diagnostic plots will be used to verify model assumptions.

If an imbalance is noted between groups for relevant baseline characteristics, sensitivity analyses will be conducted including these characteristics as covariates in the models assessing treatment effects.

The biostatistician will also conduct planned exploratory analyses to investigate potential moderators that could influence the effect of the training at 6 weeks. Pre-identified potential moderators include practice location (predominantly private vs predominantly public), baseline self rated confidence in weight management and years of clinical experience. To assess the moderation of the effect of randomised treatment group by the binary potential moderator (practice location), an interaction term between randomised group and the potential moderator, as well as terms for the randomised group and the potential moderator, will be included in the outcome regression model. To assess the moderation of the effect of randomised treatment group by continuous potential moderators (self rated confidence in weight management and years of clinical experience), the multivariable fractional polynomial interaction approach will be applied. This approach allows for nonlinear functional forms of the continuous potential moderator to be included in the regression model for outcomes, with the potential for separate nonlinear functional forms in each treatment group.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

online training program

online training program Participants receive access to online training program consisting of 6 e-learning modules on topics of weight management in osteoarthritis, which they will be instructed to and encourage to complete over the 6 intervention period.

Group Type EXPERIMENTAL

Online training program in weight management for osteoarthritis

Intervention Type OTHER

An evidence based online education training program for physiotherapists in weight management for osteoarthritis. Training modules cover the following topic areas:

1. Overweight and obesity and osteoarthritis
2. Overview of weight regulation, overweight and obesity
3. Examining weight stigma in physiotherapy and personal beliefs about weight
4. Communication approach for addressing weight management
5. Interventions for weight management
6. Health behaviour change support

These 6 e-learning modules comprise the online training program, access to which comprises the study intervention.

control group

control group Participants do NOT receive access to the online training program consisting of 6 e-learning modules on topics of weight management in osteoarthritis during the intervention period.
