|Osteoarthritis Overweight and Obesity||Other: Online training program in weight management for osteoarthritis||Not Applicable|
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.

Experimental: 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.
Other: Online training program in weight management for osteoarthritis
An evidence based online education training program for physiotherapists in weight management for osteoarthritis. Training modules cover the following topic areas:
These 6 e-learning modules comprise the online training program, access to which comprises the study intervention.
No 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.
- Self-reported confidence in knowledge about weight management for patients with osteoarthritis [ Time Frame: Change from baseline at 6 weeks post randomization ]Measured using an expert-developed, customized self-reported questionnaire exploring physiotherapists' perceived confidence in knowledge about weight management in osteoarthritis. Total score out of 70 possible points calculated from the responses to 14 Likert Scale (1-5) questions where higher values indicate higher confidence and lower values lower confidence in knowledge
- Self-reported confidence in clinical skills for weight management for patients with osteoarthritis [ Time Frame: Change from baseline at 6 weeks post randomization ]Measured using an expert-developed, customized self-reported questionnaire exploring physiotherapists' perceived confidence in clinical skills for weight management in osteoarthritis. Total score out of 45 possible points calculated from the responses to 9 Likert Scale (1-5) questions where higher values indicate higher confidence and lower values lower confidence in clinical skills.
- Self-perceived competence in nutrition care to patients with chronic disease [ Time Frame: Change from baseline at 6 weeks post randomization ]Measured using the NUTCOMP Questionnaire, a validated six section questionnaire (four sections scored, two unscored) developed to explore health care professional's perceived competence of the provision of nutrition care. Total score out of 175 possible points calculated from the responses to the Likert Scale (1-5) for each of the 35 questions, where higher values indicate higher confidence and lower values, lower confidence.
- Weight stigmatized attitudes [ Time Frame: Change from baseline at 6 weeks post randomization ]Measured by the Anti-Fat Attitudes questionnaire which comprises 13 statements about beliefs about weight (categorized under Dislike, Fear and Willpower) which respondents answer on a 10 point 0-9 Likert type scale, where 0 = very strongly disagree and 9 = very strongly agree. Total score calculated by response to each statement out of eight. The 3 subscales (dislike, fear and willpower) will also be reported.
- Completion of training modules (process measure) [ Time Frame: Throughout 6 week intervention period ]Data will be collected through the learning management system platform. Completion of module will be categorized by passing end of module quiz with 100%. (Repeat attempts allowed). Number of modules completed reported.
- Usefulness of modules (process measure) [ Time Frame: Throughout 6 week intervention period ]Self-reported using bespoke 4-item questionnaire upon completion of each module. Measured using a 5-point Likert scale from 1= strongly disagree to 5 = strongly agree. Items scored individually, higher scores for each item represent positive impressions towards training
- Structure and content of modules (process measure) [ Time Frame: Throughout 6 week intervention period ]Impressions of module length and module content self reported using two custom questions, each assessed as one of 3 multi-choice options. Results for each multichoice option presented as a percentage for the 2 custom questions
- Time to complete each module (process measure) [ Time Frame: Throughout 6 week intervention period ]Self-reported upon completion of each individual module (built into module quiz). Reported in minutes
