To examine the extent to which health promotion research is providing an empirical basis for the diffusion and institutionalization of effective interventions, we conducted a systematic audit of all articles in 12 public health and health promotion journals for the 1994 calendar year. We identified empirical/non-empirical and health promotion/non-health promotion articles. For each study, the health behaviours or outcomes studied, the target group, gender and setting were categorized. Each study was also categorized as belonging to one of four stages: basic research and development, innovation development, diffusion research, and research into institutionalization or policy implementation. Of all articles coded (n = 1210), 33.9% were identified as non-research, 39.5% were health promotion research and 26.6% were non-health promotion research. The vast majority of studies fell within the basic research and development stage (89.6%), with less than 1% categorized as diffusion research and only 5% as institutionalization or policy implementation research. The published studies reviewed provide a limited empirical basis for diffusion and institutionalization of health promotion programs. These findings suggest a need to more systematically monitor research input (funding) and research output (publications), and to develop a more explicit focus on the relevance of the stages of research innovation and development, the issues and/or behaviours addressed, the target population, and the research setting.

The benefit of any public health intervention strategy is determined not only by its efficacy and effectiveness, but by the extent to which it is appropriately adopted and implemented, so that there is an impact on the health of individuals, groups of individuals in the community and, ultimately, the population-at-large. In a recent issue of the Canadian Journal of Public Health devoted to an analysis of issues related to dissemination research, Johnson et al. make the observation that despite the mushrooming of knowledge, "the gap between knowledge generation and knowledge use or application remains problematic" (Johnson et al., 1996
While it is clear that the transfer of knowledge into practice is essential in order to improve health promotion practice (Oldenburg et al., 1996
), the availability of relevant research findings does not in itself guarantee good practice. Such knowledge transfer involves the development of formal research policies, formalized organizational and structural support, appropriate and targeted funding, formal monitoring of research activity and its dissemination, and ongoing training for both researchers and practitioners (Nutbeam, 1996
). An important intermediate step, however, is for research findings to be appropriately disseminated, in particular, by their publication in peer-reviewed journals.
Models of health promotion program development, such as those proposed by Greenwald and Cullen (1984), and Flay (1992), identify stages in the development, research and evaluation of interventions for a defined problem. Such models have been useful for conceptualizing the steps involved in developing and researching interventions, and for establishing their efficacy and effectiveness. However, they do not specifically identify links with the subsequent steps involved in planning more widespread program adoption, implementation and sustainability as discussed by a number of researchers (e.g. Parcel et al., 1990
; Kok, 1993
).
We examined health promotion research published during 1994 in 12 peer-reviewed public health and health promotion journals, focussing on their stage from basic research and development, through to diffusion and institutionalization.

Selection of journals
Health promotion research is widely dispersed in the peer-reviewed literature of public health, preventive medicine, behavioural sciences, health education and other areas. To identify a small number of key journals for review, 10 prominent international health promotion researchers and practitioners, with varying areas of interest, were each asked to nominate 10 influential journals in the areas of preventive medicine, health education/promotion and public health. From a list of 48 journals identified, all papers published during the year 1994 for those journals which were nominated by at least three respondents, were included in the current audit. The 12 journals identified, the number of nominations received and their journal impact factors, if available, are listed in Table I
|
For the purposes of this research, we used the more focused definition of health promotion proposed by Green and Kreuter (1979, p. 161), i.e. "health promotion is any combination of health education and related organizational, political and economic interventions designed to facilitate behavioural and environmental changes conducive to health". This definition was operationalized to include:
- Intervention and non-intervention research which involved measurement of health-related behaviours or outcomes identified as national health promotion priorities for Australia (Nutbeam et al., 1993
) and the US (USDHHS, 1991). Health promotion research was not restricted to intervention studies, and both correlational and experimental studies were included if they dealt with a health-related behaviour.
- Studies of social and cultural factors, environmental factors, and policies believed to influence health behaviours and health more generally.
- Empirical research only. Literature reviews or non-data based articles (e.g. Robertson and Minkler, 1994
; Waller, 1994
) and meta-analyses (e.g. Pollitt et al., 1994) were not considered health promotion research for the purposes of this study.
- Studies where the main focus was on primary and secondary prevention research conducted in either the entire population or a sub-population (e.g. Davidson et al, 1994
; Donaldson et al., 1994
; Flynn et al, 1994
). Studies of patient groups such as the case management of patients with breast cancer (e.g. Howe et al., 1994
) or the coping styles of patients with AIDS (e.g. Fleishman and Fogel, 1994
) were coded as non-health promotion research because primary or secondary preventive approaches were not the focus of the research.
Coding of articles
All journal issues for year 1994 were reviewed. A standardized coding system was developed for the study and codes were entered directly onto a database. All studies were coded on as many dimensions as possible, so that the characteristics of health promotion and non-health promotion studies could be compared and quantified. The codes used are summarized in Table II
. Categorizing of study design and stage was based on a staged model of innovation development and diffusion of health promotion programs discussed in detail elsewhere (Oldenburg et al., 1996
, 1997
). Briefly, these included the stages of Research and Development (i.e. descriptive and intervention research and methods development), Innovation Development (i.e. research identifying target audiences and strategies for program diffusion), Diffusion Research (i.e. research evaluating methods for dissemination, adoption, implementation and maintenance of programs) and Institutionalization Research (i.e. policy implementation or ongoing evaluation).

Inter-coder reliability
One author (M. F.) acted as primary coder for all articles (1210 articles). Fifteen percent of these articles (181) were coded for reliability purposes by another author (J. S.). Inter-coder reliability was determined by percent agreement (mean: 87.56%; range 70.64100%; median 87.03%) and
coefficients (mean: 0.77; range 0.450.97; median 0.74). See Table II| Results |

The vast majority of published studies for both health promotion and non-health promotion research fell within the Research and Development stage (89.15%). Within this stage approximately 63% of the studies were of a Descriptive type, 16% were Intervention-Based and 11% were categorized as Methods Development. Table IV
|
In the subsequent stages, 5% of the studies were categorized as Innovation Development. Examples include monitoring difficulties and breast feeding rates (Lund-Adams and Heywood, 1994), early detection and screening costs for breast cancer (Salkeld and Gerard, 1994
Health behaviours
For the health promotion research category (see Figure 2
), most research audited was conducted with behaviours associated with risk for cardiovascular disease and cancer (76%), with relatively little intervention research addressing health areas such as injury prevention (7%) or mental health (1%). It is also interesting to track the stage and quality of research for each behaviour. Smoking research, for example, would appear to be relatively advanced with proportionately high study representation in intervention research (33% of all smoking studies coded) particularly in the form of randomized controlled trials (16% of all smoking studies coded), as well as the more advanced stages of innovation development, diffusion and institutionalization (22% of all smoking studies coded). Research into alcohol issues and screening has also progressed well into these higher stages (28% of all coded screening studies and 24% of all coded alcohol studies were identified as within the stages of diffusion and institutionalization). On the other hand, research into physical activity, sun exposure, mental health and violence, for example, had not moved beyond intervention research to the more advanced stages of diffusion or institutionalization at all in the studies reviewed for the year 1994.

Three major findings have arisen from this audit which provides a detailed examination of all articles published in 12 international public health and health promotion journals for the year 1994. Firstly, the majority of published health promotion research still falls within the earlier stages of health promotion research and development, with less than 11% of studies overall being classified as diffusion or institutionalization research. Secondly, in the journals surveyed, most research was conducted with behaviours associated with cardiovascular disease and cancer, with relatively little emphasis being placed on other important health outcomes or behaviours, such as those related to injury or mental health. Thirdly, most published research reports on efforts directed at behaviour change in individuals or small groups rather than research into social, environmental, ecological or policy approaches.
These findings would appear to support the often cited comment made by practitioners that much health promotion research is difficult to apply in real-life settings, is not relevant to many of the health issues that confront them or does not adequately inform the strategies which they are often required to use in such situations (Glanz and Oldenburg, 1997
). There are obviously many other reasons for the gulf which exists between health promotion researcher and practitioner, in addition to the perception of practitioners that the research base does not adequately meet their needs as practitioners. These have been described by Kottke et al. (1990) and others (e.g. Catford, 1995
).
Several contemporary health promotion models emphasize the need for interventions at multiple levels, including psychological, socio-environmental and policy components (e.g. Green and Kreuter, 1991
; Stokols, 1992
; Kok, 1993
; Winett, 1995
). Working with multiple sectors of the community, altering environments and influencing health-related policies are regarded as hallmarks of desirable health promotion practice, but the scientific basis for these is still far from clear. There is limited research evidence available in these areas because investigators have not studied many of the relevant variables nor researched many of these complex strategies and approaches. In the published research audited in this study, most studies focused solely on individuals. Only 1% of the health promotion articles studied families and/or small groups, 6.5% studied systems or settings and 5.9% studied change agents (see Table V
). It seems that contemporary health promotion research appears not to be focussing sufficiently on the social or environmental contexts of health behaviours, nor the appropriate methods for implementing social or environmentally focused health promotion strategies (Kottke et al., 1990
).
Limitations of our study include the review of only a small number of journals in a large and diverse field. Journals specializing in specific health behaviours (such as those related to tobacco and cancer control, HIV/AIDS, and drugs and alcohol) were not selected by our criteria and their inclusion could have led to different results. However, reviewing speciality journals for all health behaviours was not feasible. It is also possible, but not likely, that articles published in 1994 are not representative of the spectrum of health promotion research published in recent years.
Strengths of the study include the coding of all articles from those journals which were identified by international health behaviour and health promotion researchers as being the most significant. The acceptable level of inter-coder reliability, and the application of a model of the phases of health promotion program research, diffusion and sustainability, are considered additional strengths. These codes can be used to assess journals in future years, and track changes in the emphasis and scope of the research.
The results of this audit strongly suggest that there is an inadequate research base for the diffusion and institutionalization of health promotion programs. However, most health promotion programs have not been sufficiently tested and hence their diffusion is not warranted. The authors hope these results stimulate greater interest not only in the conduct of program diffusion research, but also in the greater problem of how to improve and expand the practice of health promotion so that more people can benefit from effective interventions. Unlike other health interventions, especially surgery and pharmacology, there are no well established pathways to diffusion. It is the joint responsibility of health promotion researchers and practitioners to develop appropriate pathways for effective health promotion interventions.
It would seem that to improve the translation of public health intervention and health promotion research into practice and relevant policy, it will be important to encourage: intervention research directed at those targeted behaviours that have not been studied adequately to date; appropriately staged research to ensure that efficacy and effectiveness are proven prior to policy and community-wide implementation; and, most importantly, research which directly addresses methods of diffusing effective programs and implementing social and environmental strategies to promote better health. However, different types of research designs and methods to those which most public health researchers have been trained in are required for researching the diffusion and institutionalization of public health strategies and programs. Moreover, funding priorities need to be set which target those health issues which are in need of research and those stages of program development which are least developed. As argued recently by Haines and Jones (1994, p. 1491) in relation to medical and health innovations more generally, "the challenge is to promote the uptake of innovations that have been shown to be effective, to delay the spread of those that have not yet been shown to be effective, and to prevent the uptake of ineffective programs".
