The
Trial
• The primary aim is to evaluate the efficacy of a community
social service case-worker delivered smoking cessation
intervention for socially disadvantaged smokers
• The study design is a randomised controlled trial
• The primary outcome measure is CO verified continuous
abstinence at 6 months follow-up
3
The Call it Quits smoker (n = 309)

The case-worker delivered intervention:
Key components
•
•
•
•
•
•
•
Delivered by trained volunteer case-workers
Systematically (electronically) assessing and recording smoking status
in client notes
Tailored (based on print-out)
Provision of advice to quit and behavioural counselling, motivational
interviewing if required over two face-to-face sessions
Free nicotine replacement therapy
Buddy system
Flexible follow-up through telephone calls, or drop-ins
But what are our intervention participants really receiving?
5
The aims of the current study
1. Assess volunteer case-worker fidelity to the Call it
Quits intervention manual using BCT analysis
2. Assess the effectiveness of BCT performance
feedback in improving fidelity to intervention manual
6
Methods
•
Pre and post test study embedded in one intervention trial (Call it Quits)
•
6-week pre-test period of recording counselling sessions
•
6-week period post-intervention of recording counselling sessions
•
Main outcome:
– Proportion of each manual specified BCT delivered pre and post
7
Methods
8
Intervention manual coded using BCT smoking
cessation framework
Pre-test: Counselling sessions audio recorded and
transcribed
Code transcriptions - BCTs
Intervention: Volunteer case-workers provided with
BCT performance feedback
Post-test: Counselling sessions audio recorded and
transcribed
Code transcriptions - BCTs
Results: BCTs coded in the manual
Tailor interaction appropriately
Facilitate goal setting
Boost motivation and self efficacy
Prompt review of set goals
Provide feedback on current behaviour and progress
Advise on stop smoking medication
Provide rewards contingent on not smoking
Advise on/facilitate the use of social support
Prompt commitment from the client there and then
Ask about experience of stop smoking medication
that the smoker is currently using
Provide rewards contingent on effort or progress
Give options for additional and later support
Facilitate identification of reasons for wanting and not
wanting to stop smoking
General communication approach
Explain the importance of abrupt cessation
Facilitate relapse prevention and coping
Conduct motivational interviewing
Promote cut-down-quit
Facilitate barrier identification and problem solving
Advise on management of mental health problems
Information gathering and assessment
Assess alcohol or drug use disorder
Facilitate action planning/develop a treatment plan
Arrange follow-up session

BCT Performance feedback intervention
Group feedback session outlining:
– Number of recordings per volunteer
– BCTs specified in manual
– BCTs delivered by each volunteer (anonymous)
– Positive reinforcement
– Discussion of BCTs, identification of aids to help
boost BCT use
Individual performance feedback letters including:
– Length of sessions (in minutes)
– List of BCTs identified and positive reinforcement
– List of BCTs not coded
– Goal setting – increase unused BCTs in 6 months

Desktop checklist with ‘top 5’ BCTs – goal for improvement
In face-to-face sessions
1. Explain the importance of abrupt cessation
2. Prompt commitment from the client there and then
3. Facilitate action planning/develop a treatment plan
4. Facilitate goal setting
5. Advise on stop smoking medication
In telephone follow-up calls
1. Prompt review of set goals
2. Provide feedback on current behaviour and progress
3. Boost motivation and self-efficacy
4. Facilitate relapse prevention and coping
5. Provide rewards contingent on effort or progress
Next steps
•
Continue coding post-test sessions
•
Compare pre and post test use of manual specified BCTs
•
Assess by
– session type (face to face, telephone follow-up)
– duration,
– volunteer
– BCT
•
Assess inter-rater reliability for new BCTs
