Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The participants who are randomly allocated to receive the Motivational Interviewing intervention will receive usual care they would receive in the community plus the 8 weekly 30-minute sessions of motivational interviewing (Miller & Rollnick, 2002, 2013) over the telephone for 8 weeks. This intervention is a directive style of communication in which the person delivering the intervention works collaboratively with the client to assist the client to increase his/her motivation to change their behaviour (in this case physical activity). This is done through a process of clients forming their own arguments for change which builds the clients importance and confidence of change (Miller & Rollnick, 2002, 2013). Motivational Interviewing has been demonstrated to lead to health behaviour change, in non-hip fracture populations, in several large meta-analytic studies (Hettema et al., 2005; Rubak et al., 2005; Lundahl et al., 2010).

Eligibility
Key inclusion criteria
1. They have had a hip fracture and are now living at home independently within 6 months of discharge
2. They are aged over 65 years
3. They speak conversational English
4. They are currently insufficiently active – as defined by obtaining less than 30 minutes of activity most days of the week
Minimum age
65 Years
Maximum age
89 Years
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. They have a cognitive impairment of any kind – this is because the Motivational Interviewing intervention is a talking intervention that requires people to be able to think clearly and generate their own ideas of how they can change their behaviour
2. They score in the severe range of depression or anxiety as measured by the Depression Anxiety and Stress Scale (DASS: Lovibond & Lovibond, 1995)
3. They do not speak conversational English - this is because the Motivational Interviewing intervention is a talking intervention and the person delivering the intervention only speaks English and there are not sufficient funds to employ another person who is able to speak in other languages
4. They are less than 65 years of age – this is because the population of interest for the current study is people 65+, because this is the group who is most likely to experience problems with reduced mobility following a hip fracture
5. They are highly dependent on medical care, in either high level or low level care – this is because the population of interest is people living independently in the community who are capable of becoming more active
6. They are already sufficiently active, as defined as obtaining at least 30 minutes of activity most days of the week

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Method of randomisation - Participants will be allocated to the intervention or usual care group based on a random number sequence produced by a random number generator produced by MS excel. Specific details about group allocation for each participant will be sealed in sequentially numbered opaque envelopes prepared by an independent researcher.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
the use of a random number generator produced by MS excel

Statistical methods / analysis
Data on outcome measures will be analysed on an intention-to-treat basis. Groups will be compared on primary and secondary outcomes using Analysis of Covariance (ANCOVA) which will compare the group means at week 8 using baseline scores as covariates. Effect sizes will be calculated, by calculating Hedges g, in order to be able to obtain a measure of the magnitude of the impact of the intervention.

Summary
Brief summary
The primary aim of the study is to examine if a telephone based intervention designed to increase confidence and motivation (i.e. Motivational Interviewing) increases physical activity in people living in the community following a hip fracture. Secondary aims relate to the effect of this intervention on confidence, quality of life, mental health and mobility.
