Tobacco kills nearly 6 million people worldwide, and causes hundreds of billions of dollars of economic damage each year [1]. New Zealand (NZ) has had a progressive tobacco control programme since 1994 with sustained strong tobacco control policies, for example smoke-free environments, increasing tax on tobacco, and public health programmes, and since 2000 an increasing range of cessation support, such as, the national Quitline [2]. This comprehensive programme has led to a drop in daily smoking prevalence from 26.6% in 1997 to 19.2% in 2009 [3, 4]. However, each year 4500-5000 people are still killed by smoking or exposure to second-hand smoke [3]. Considerable inequity exists across the population with smoking prevalence among Māori at 45.1% and Pacific Island people at 30.3% compared to New Zealand European at 19.7% rates [3].
The government of New Zealand has set an ambitious goal for the country to be smokefree, defined as “a smoking prevalence of less than 5%, with tobacco being difficult to obtain and children not exposed to smoking”, by 2025. To achieve this, new and innovative strategies are needed to bring about rapid reduction in smoking prevalence. Generic population tobacco control programmes, however, have increased the gap between different SES groups and ethnic groups [5]. Therefore there is a need for programmes specifically focused on disadvantaged population groups.
Interventions that have shown promise internationally are stop smoking competitions where usually individuals who smoke stop for a chance to win a prize of cash or products. Quit and win competitions have run all over the world since the early 1980s [6] with long term quit rates ranging from 8% to 20% at 12-months [7]. Short term quit rates at the end of the competition have been as high as 66% [8]. Only a few quit and win competitions have focused on disadvantaged population groups. However, one quit and win competition aimed at low-income smokers in the United States had significantly higher overall quit rates in the treatment group with 23% (compared to 9% in the control group) still quit at 12-months [9]. Māori and Pacific Island people in NZ are overrepresented among lower socio-economic groups [10, 11]. A quit and win competition was piloted in 2000 in the Hawke’s Bay region of New Zealand and achieved quit rates of 40% at 12 months follow-up [12]. The competition included a high proportion of Māori (32% compared to 22% of the total Hawkes Bay population).
Given NZ’s heightened urgency to increase quitting on a mass scale, and the positive potential for quit and win competitions to be attractive to and more effective at bringing about cessation among smokers from lower socio-economic groups it is time to test quit and win competitions for Māori and Pacific Island people [13]. We propose a quit and win competition which is aligned more with Indigenous people’ cultural principles and beliefs. The main aim of this paper is to describe how knowledge of Indigenous people’s practices and principles can be incorporated with proven effective smoking cessation support into a culturally appropriate cessation intervention WERO (WERO in the Māori language means challenge). Included in the aim is describing identified cultural principles and practices that can be used in a cessation competition and describing identified effective cessation elements that could be incorporated. A final aim of the paper is to describe the WERO study protocol.
Cultural principles and practices
Designing public health interventions consistent with the cultural beliefs and practices of target populations is believed to lead to better receptivity, acceptance and salience of health information and programs [14].
Competitiveness
The indigenous people of NZ are collectively called Māori but there are many tribes within the Māori nation. Tribal identity is strong and historically marked by inter-tribal rivalry and competition, which carries on in modern times [15, 16]. This rivalry and competition is not a means of excluding others, rather it develops and maintains a sense of collective unity, loyalty and belonging within the group [16]. Kapa haka (traditional Māori performing arts) regional and national competitions are an important way to construct a secure Māori identity and the skills learned can be transferred into other areas of life [17]. Māori and Pacific Island peoples have higher participation rates in sport, recreation and physical activities than other ethnic groups in NZ [18]. For instance, kapa haka contests are well-attended and popular. Te Matatini National Festival which is held every two years attracts up to 30,000 participants and visitors [19]. Other group competitions include Top Town, where communities compete for their town, and inter-marae (traditional tribal meeting place) sports events, to celebrate family values, strengthen kinship and assist in maintaining cultural values and knowledge in an atmosphere of friendly competition and healthy lifestyles [20]. Among Pacific Island people, competitive sports such as kilikiti (a Samoan form of cricket) are popular, with high participation rates [21]. These contests incorporate competitiveness with cultural elements and encourage community participation, all of which are key components for effective health interventions for Indigenous people [22]. Furthermore, competitions have also been used to encourage behaviour changes, such as weight loss (for example [23]) and seatbelt usage among teenagers (for example [24]).
Family centred
Like many other Indigenous people, Māori and Pacific Island peoples are whānau (family) centred, where the wellbeing of the family, church, extended family and culture is often placed above personal health. The NZ government Whānau Ora policy was developed to establish and recognise the centrality of the family in the delivery of health and social services. Recently, health provider organisations with a sole focus on Pacific Island peoples have been included in the Whānau Ora programme [25]. Whānau Ora is an inclusive approach to providing health services to families across New Zealand. It builds on the strengths and capabilities present in families as a whole, rather than focusing separately on individual members and their problems [25, 26].
A smoker’s motivation to smoke is affected by environmental, social, economic and personal determinants [27]. Māori smoking cessation services provide support to individuals and families to quit together. Support is typically extended to other smokers in the presenting individuals’ friendship network, household or work environment [28]. Group cessation approaches therefore align with Māori and Pacific Island whānau centred values and practices and increase the number of smokers assisted at a time.
Fundraising
Another common Indigenous culturally embedded practice is fundraising. Both Māori and Pacific Island cultures organise and participate in fundraising for schools, churches, cultural events and competitions, sports, marae and family reunions [29]. Voluntary activity, fundraising, is for many Māori and Pacific Island people an act of service to their whānau, and iwi (tribe) and one way of fulfilling family and social obligations and responsibilities. This activity is central to identity and to the maintenance of culture and traditions. In 2001, Māori were more likely than non-Māori to have been involved in unpaid activities outside the household [30]. Many Pacific Island people see volunteering as a moral and ethical responsibility, and a cultural duty that is passed on through traditional roles and responsibilities to the collective group and their family [30, 31].
Effective elements of smoking cessation competitions
Most quit and win contests include a cessation support programme in addition to the contest [32]. A few quit and win studies have investigated the effectiveness of general cessation support, such as pharmacological support, social support, use of incentives, and technology, in a quit and win context [33–36]. Elements of a smoking cessation competition are considered effective when they significantly impact the chances of short-term and/or long-term abstinence.
Pharmacological support
In general, the use of any type of pharmacological support is likely to increase cessation rates [32, 33, 37–39]. Nicotine Replacement Therapy (NRT) increases the chances of successfully stopping smoking by 50% to 70% [39]. Similar findings have been found for Māori: smokers who took bupropion doubled their cessation rates in comparison with the placebo group [40].
When comparing NRT use with or without competition, Maheu et al. [41] found that combining contest and NRT led to a significant increase in number of smokefree weeks, in comparison with NRT without contest. However, another study found that there was no significant long-term difference in cessation rates between those quitters who used no pharmacological support and those who did [8].
Social support
Social support, given by family, friends and co-workers, has a positive influence on smoking cessation in general [42, 43] and has a particularly significant impact when combined with quit and win competitions [33, 34, 37, 44, 45]. Cessation rates are higher for contestants with a designated support person compared with those without [34, 44]. One study found that 60% of their contestants utilised a designated support person, which reflects the importance of this type of support [44]. The type of relationship that the support person had with their smoker has an influence as well where having a spouse or partner as a buddy was most effective [37].
Incentives
Cash incentives have been shown to boost motivation to quit [45, 46]. Although the effects on long-term abstinence are not yet clear, there is a short-term effect [32]. For example, in one study 57% of the participants stated that the chance of winning a cash prize had helped them to remain abstinent [46].
Technology to support quitting
There has been a rise in use of e-Health, such as internet, smartphone and tablet PC applications (apps), to prompt and support behaviour change to improve health. Such technologies have the potential to reach large numbers of people [47, 48]. Internet-based social support groups can connect people in disparate locations and can provide support at all times of the day, at a minimal cost [47, 49]. Often posts on website message boards allow quick responses by peers, indicating that social networking may be beneficial to prevent relapse by smokers trying to quit, especially in comparison to the time it may take to seek professional help [49].
In the area of smoking cessation, the internet has provided a platform for interactive support. One such social network for tobacco users, QuitNet, has a large number of members who persist over time, even after quitting. This shows that social networking may prevent relapse for a lengthy period of time [48]. The use of the internet for smoking cessation is most effective when there is a high frequency of visits to the website. A randomised controlled trial which tested the effectiveness of internet use, in conjunction with other smoking cessation interventions such as NRT, found that the number of times participants used the website per week was significantly related to abstinence both at the end of the treatment period and at the 6 month follow up; yet purely access to the website was not [50]. Smartphone (mobile phones which can also run computer programmes or apps) and tablet PC apps have also been used to assist with smoking cessation. However, while there is a large amount of research about the use of other types of technology to promote behaviour change, there is very little research in this area, given how recently apps have been introduced.
Integrating cultural and smoking cessation elements into the WERO intervention
Incorporating Māori and Pacific Island people’s inherent interest in competition into a cessation intervention could potentially increase attractiveness of the intervention and thereby increase uptake and retention. However, to the best of our knowledge, no Indigenous-informed quit and win contest has been trialled and published. The vast majority of Quit and Win competitions pitch individuals against each other [7]. But because of the strong family-community centrality of many Indigenous peoples, group-, rather than individual-, based competition may be more appropriate. Therefore, the main part of the intervention was an inter-team contest where the team with the most quitters at end of competition won a prize.
In order to increase the effectiveness of the contest, other cultural and smoking cessation elements were also included. A contest that ties in with Māori and Pacific Island people’s practises of fundraising may be attractive. Benefitting their community may be a stronger motivator to quit than individual benefit. Therefore, in WERO, the winning prize did not go to the team participants, but rather an organisation or charity of their choice. This fundraising aspect is expected to appeal to participants’ existing sense of duty to raise funds for cultural or local community events and other needs. This may provide additional motivation over and above any motivation to quit for their own benefit.
Further, members of each team had their progress displayed on a public website. Lastly, given the substantial and well documented increase in quit success with the use of pharmacological support, these were also included in the intervention.
WERO intervention
WERO participants compete in teams of ten current smokers, the majority of which knew each other prior to the intervention, which boosts peer social support and enable the dynamics of whanaungatanga (a relationship through familial and shared experiences) to operate. Each team appoints a ‘coach’ whose role is to encourage their team and facilitate team meetings and activities. Criteria for the coaches are that they are non-smokers or ex-smokers, and that they are willing to support their team to quit over the contest period.
The team with the most smokefree members at the end of the competition wins. If multiple teams have the same number of smokefree team members, one winner will be randomly drawn by a computer random digit generator. The prize of $5000 goes to their nominated charity or community organisation. If a team member tries to cheat the competition, team members would continue to receive support to quit but they would be excluded from the prize draw.
WERO participants are encouraged and supported to use NRT, such as, nicotine patches, gum or lozenges, which in New Zealand can be obtained using a Quitcard for as little $5 for 8 weeks supply. They are also told about Champix (varenicline) and Zyban (bupropion) which are subsidised, but only available on prescription. The New Zealand smoking cessation guidelines recommend NRT be used for a course of at least 8 weeks [51], thus the WERO competition period will run for 3 months.
An interactive website and iPad app is used to strengthen the sense of team and inter-team competitiveness by making the smoking status of team members and the team as a whole publicly visible. To keep all teams up-to-date on their own and other team’s performances, weekly updates of smoking status are requested from the regional Coordinators. Teams and supporters are also able to post questions, comments or support, to the team page. Frequent interaction with the website should help reduce relapse, and will be encouraged with the use of a prize of $500 for the team that utilises their team page the most. In addition, the website and app provides information in the style of tips on quitting and relapse prevention. Participants’ questions or comments about withdrawal symptoms and trigger situations on their web page can also be answered and commented on by the study’s primary investigator, an expert in smoking cessation.
Although it would be preferable to develop the app for multiple operating systems (OS), in the interests of cost-containment it was decided to develop for one OS and form-factor for this pilot. Further, the study team did not have the capacity to test the performance of an app across the wide range of tablets available. The iPad was chosen over other types of tablets as it has a wide user base and high levels of usability compared to other tablet PC operating systems such as Windows and Android.
