Physical activity (PA) benefits both physical and psychological health, yet the majority of UK adults are physically inactive. "Exercise for Health" (EFH) is a General Practitioner (GP) exercise referral scheme run in Liverpool for people who are inactive with a medical condition. Patients are referred by their GP practice, where they receive 12 weeks of subsidised exercise classes at their local leisure or community centre.
In 2012, one of the thirteen EFH centres (Centre A) introduced some changes to try and improve EFH at their centre. These changes included:
This non-randomised study will compare the effectiveness of the adapted EFH (Centre A) with standard EFH delivery (Centre B). All participants referred to centre A (n=100 approx) or centre B (n=100 approx) during the study period will be invited to take part. Changes in self-reported PA, PA self-efficacy and psychological wellbeing will be measured at the end of EFH (12 weeks) and at 12-month follow-up. A subsample of participants (n=15 from each centre) will take part in qualitative interviews to explore the factors that contribute to effectiveness.
A secondary aim is to explore psychological factors contributing to any differences between the two centres. Self-determination theory suggests that where participants feel they are offered choice, feel they are competent at exercise, and feel connected to people they exercise with, they will be more intrinsically motivated and more likely to continue exercising. Therefore it is hypothesised that participants attending the adapted EFH will be more motivated and more likely to continue exercising.
This mixed-method observational study will compare the short- and long-term effectiveness of two different delivery approaches of an exercise referral scheme (Exercise for Health, EFH). As the intervention is already in widespread use randomisation is not feasible, therefore a case control design is adopted to compare the effectiveness of an adapted EFH scheme (delivered at centre A) with the standard EFH scheme (delivered at centre B). Centre B is selected as the comparison centre due to its similarity to centre A on socio-demographic markers (e.g. number of EFH referrals, socioeconomic make-up of local population).
Although the adapted scheme has not drawn overtly from Self-determination Theory (SDT), it is hypothesised that the adapted scheme promotes greater environmental support of SDT-based psychological needs for participants than the standard EFH scheme. Autonomy is promoted through the increased choice offered through daily sessions and the involvement of the patient in their decision whether to take up the scheme, competence is encouraged through the tailoring of classes to the ability of EFH participants and the opportunity to observe similar others, and relatedness is supported through the social assimilation of participants through regular group activities.
It is hypothesised that:

| Adapted Exercise for Health (EFH) scheme | Behavioral | 12-week subsidised exercise programme at local authority-run leisure centres. Each participant receives a programme of activities tailored to their needs, based on a standard recommendation of two exercise sessions per week. In February 2012, Centre A introduced some changes to the EFH scheme as follows:
Although subsidised access to mainstream group classes and swim sessions (i.e. includes all leisure centre members) is also available, this option is not openly advertised on the adapted scheme. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in self-reported physical activity (PA) | Self-reported PA will be measured using the vigorous PA, moderate PA and walking items of the short version of the International Physical Activity Questionnaire (IPAQ). The short-IPAQ is a 7-day recall self-administered tool that measures intensity, frequency and duration of PA and provides a total estimate of energy expenditure. A total score of MET-minutes/week will be calculated according to the IPAQ scoring protocol, which is available to download from http://www.ipaq.ki.se/ipaq.htm | Baseline, 12 weeks, 12 months |
| Measure | Description | Time Frame |
|---|---|---|
| Change in physical activity self-efficacy | A two-item measure of PA self-efficacy (SE) was developed to reflect the intervention aims. Item one measures self-efficacy to adhere to the Exercise for Health programme ("how confident are you that you can attend exercise sessions twice a week?"); item two measures self-efficacy to adhere to a physically active lifestyle in general ("how confident are you that you can be moderately physically active for at least 30 minutes on 5 days of the week?"). Participants are asked to rate their confidence on a scale of 0 (not at all confident) to 10 (extremely confident). |
| Measure | Description | Time Frame |
|---|---|---|
| Self-determination theory variables | Needs support (4 weeks and 12 weeks only) will be measured using a 15-item needs support (NS) tool that assesses participant perceptions of the extent to which their exercise referral instructors provide support for autonomy, structure (linked to competence) and involvement (linked to relatedness). Psychological needs satisfaction will be measured using the Psychological Need Satisfaction in Exercise Scale (PNSE). The PNSE is an 18-item tool designed to measure participants' perceived autonomy, competence and relatedness in an exercise context. Behavioural regulation of exercise will be measured using the revised Behavioural Regulation in Exercise Questionnaire (BREQ-2), which contains 19 items exploring reasons why people exercise. The scale includes items measuring amotivation, external regulation, introjected regulation, identified regulation and intrinsic motivation of exercise behaviour. Four additional items will be included to assess integrated regulation. |

| Standard Exercise for Health (EFH) scheme | Behavioral | 12-week subsidised exercise programme at local authority-run leisure centres. Each participant receives a programme of activities tailored to their needs, based on a standard recommendation of two exercise sessions per week. The scheme includes exclusive EFH gym sessions (i.e. includes EFH participants only) on two to three days of the week, plus subsidised access to mainstream group classes and swim sessions (i.e. includes all leisure centre members). |

| Baseline, 12 weeks, 12 months |
| Change in psychological wellbeing | Psychological wellbeing will be measured using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). WEMWBS is a 14-item positively worded measure containing items related to psychological functioning (e.g. "I've been thinking clearly") and subjective well-being (e.g. "I've been feeling cheerful"). Participants are asked to rate on a likert scale of 1 (none of the time) to 5 (all of the time) how well each statement describes their experiences over the last two weeks. | Baseline, 12 weeks, 12 months |
| Adherence to the Exercise for Health programme | Adherence will be expressed as a percentage of the recommended twice weekly leisure centre attendance over 12 weeks. | Between baseline and 12 weeks |
| Post-intervention leisure centre attendance | The number of occasions participants attend either gym sessions, classes or swim sessions between 12 weeks and 12 months will be obtained from computerised attendance records. Two measures will be taken: the absolute number of attendances (regardless of when these occur) and regularity of attendance (i.e. number of months in which participants attend at least once). | Between 12 weeks and 12 months |
| 4 weeks, 12 weeks and 12 months |
| Qualitative interviews | Qualitative interviews with a randomly-selected subsample of participants (15 per centre) will explore the following research questions:
| 4 weeks and 12 months |
