The population distribution and geographic barriers in Canada make it problematic for physical therapists in remote and rural areas to access continuing education8,9 (Fig. 110). This lack of access leads many physical therapists in rural areas to feel professionally isolated because of a scarcity of resources and the inability to consult other health care professionals and experts in their field.9,11 This isolation is especially problematic for physical therapists in smaller specialty areas such as cardiopulmonary practice.12 Because there is less demand for courses in these areas, fewer courses are available and they are offered primarily in larger population centers. For example, the 2003 education calendar of the Canadian Physiotherapy Association indicated that 12 out of 15 continuing education courses offered over a 4-month period were geared toward orthopedic practice (primarily manual therapy courses) and only 1 course was offered outside a large city.13 With or without professional isolation, multiple work and family responsibilities, coupled with the travel costs and lost time from work, make it very difficult for physical therapists to attend continuing education conferences and workshops.14,15 Distance education that uses computer-assisted learning (CAL), including both Web-based and CD-ROM technologies, can be a solution to these problems, because it can provide increased access to education.15,16

Other benefits of Web-based instruction include access to up-to-date information and to a large pool of expertise and resources.23 Learners and instructors also can develop skills and knowledge of current technology that are relevant to current practice.28 CD-ROM applications provide another interactive, multimedia learning tool and are beneficial in enhancing distance education.29,30 In addition, Web-based and CD-ROM technologies allow for an increased ability to participate in continuing education by providing flexibility in the time and place of education.20,30
Not all areas of physical therapy education, however, can be addressed using CAL. The acquisition of psychomotor (hands-on) skills, for example, may not be conducive to CAL. On the other hand, CAL is particularly advantageous for cognitive learning, such as case-based learning31 and problem-based learning,19 and has been used more by health care professionals in recent years.
Despite the many benefits, Bates32 identified fear as the greatest barrier to using technology triggered by discomfort with technology and the lack of knowledge and skill in using it. Other disadvantages of CAL identified by learners include technical difficulties (eg, the server is "down"), lack of technical support, limited access to computers, and lack of technical skill in using computer software.24 Course developers also have identified lack of technical support, limited access to adequate computer equipment, and a large time investment as barriers to developing CD-ROM and Web-based courses.24,33
The success of continuing education programs depends highly on the interest of their users and their accessibility. It is important, therefore, to assess the readiness of physical therapists to undertake CAL that uses Web-based and CD-ROM technology and to determine the factors that may influence their ability to participate in CAL. The purposes of this study were: (1) to survey Canadian physical therapists to determine their interest in participating in continuing education using CAL methods (Web-based or CD-ROM learning) and (2) to determine whether their interest in participating in CAL was related to type of employment, area of practice, education, computer skill and access, and other demographic variables.

Questionnaire
A 3-part questionnaire was developed by the authors (available upon request from the authors). For the purposes of the survey, participants were given the following operational definition of CAL: "all or parts of course being offered by CD-ROM or on different Web sites accessed via the Internet ... discussion of course-related issues via e-mail discussion or Web-based chat rooms." Part 1 explored interest in continuing education courses specifically related to cardiopulmonary content, and the results from this part are not reported here. The primary question in part 2 asked the respondents to indicate whether they were interested in any of the following: Web-based distance courses, CD-ROMbased distance courses, distance correspondence courses, face-to-face courses, none of the above, or all of the above. Part 3 contained questions about the demographic characteristics of the sample as well as items regarding access to computers, the Internet, and CAL. An open-ended comment section in each part of the questionnaire enabled respondents to include information that was not covered by the survey questions. Only the primary question from part 2 and the information from part 3 were used for the purposes of our study.
Parts 2 and 3 of the questionnaire had been used previously for occupational therapists and physical therapists in British Columbia (n=395) who responded to a distance education needs assessment.15 The entire questionnaire (parts 13) was pretested on 31 physical therapists and occupational therapists from academic and clinical settings to identify missing or ambiguous items. Once ambiguous items were clarified, the entire questionnaire was pilot tested with 25 physical therapists to ensure clarity. These data were not included within the final data set for analysis.
Survey Questionnaire Mailing and Responses
A summary of the survey questionnaire mailing and responses is shown in Figure 2. On February 1, 2001, questionnaires were mailed to the sample of physical therapists (n=1,426) with a cover letter explaining the purpose of the study. Self-addressed, stamped envelopes were provided to encourage responses, and participants also were given the choice to fax their completed questionnaire. To improve response rates, a postcard reminder was sent 5 weeks after the initial mailing and a second copy of the survey questionnaire was sent to nonrespondents 3 months after the initial mailing. Identification numbers were placed on the questionnaires and return envelopes to help identify nonrespondents for more efficient follow-up mailings. Data collection was discontinued on July 11, 2001.

Logistic regressions and odds ratios (ORs) with their 95% confidence intervals (CIs) were determined for each independent variable related to interest in CAL. Logistic regression is used for categorical data where the dependent variable has only 2 outcomes (eg, interest or no interest in CAL).36 Logistic regression coefficients were interpreted using ORs, which indicated the likelihood of the person being interested or not interested in CAL. For OR analysis, we chose one level of each variable as a reference group for comparison of responses within each variable. For example, if a population greater than 1 million was the reference group, then relative ORs for all other levels within that variable would be computed based on the reference group's values. Because respondents were able to indicate more than one area of practice, each area of practice was managed as a separate variable with respondents classified as either practicing in that area or not. Year of graduation was managed as a continuous variable. Because the data were not normally distributed, the Mann-Whitney U test was used to detect differences.

Table 1 compares employment characteristics of the survey respondents and all licensed physical therapists in Ontario (the Canadian province with the largest population of physical therapists). Survey respondents from the licensing body appeared similar to physical therapists from Ontario in the proportion of full-time and part-time workers, proportion of public sector to private sector workers, distribution of areas of practice, and highest professional (entry-level) degree. Survey respondents from the cardiopulmonary interest groups included a greater proportion of physical therapists working in the public sector and a greater proportion practicing in the area of cardiopulmonary physical therapy care than the Ontario licensed physical therapists.

(Tab. 2). Previous experience with Web-based courses was not related to interest in participating in CAL.
Computer/Internet Access and Skill
Respondents who had access to the Internet were 6.6 times more likely to be interested in CAL than those without Internet access (OR=6.60, 95% CI=3.8211.42, P=.0001; Tab. 2). Those who had access to the Internet at both home and work were more likely to be interested in CAL than those with access only at work (OR=4.23, 95% CI=2.287.85, P=.0001; Tab. 2). The number of hours of Internet access also was a relevant factor; respondents with 2 or more hours of Internet access per week were more likely to be interested in CAL than those with less than 2 hours per week of Internet access (Tab. 2).
Another important factor was self-rated computer and Internet skills. Respondents who rated themselves as having novice computer skills were 7.7 times more likely to be interested in CAL than those who rated themselves as having no skills (OR=7.68, 95% CI=3.0819.14, P=.0001; Tab. 2). Sixty-one percent of respondents who rated themselves as having novice computer skills and 62% of those with intermediate computer skills were interested in taking a course that introduced them to the computing skills needed to engage in CAL (results not shown in Tab. 2). Interest in a course that introduced them to computing skills was higher among those who rated themselves as having novice or intermediate skills than among those who rated themselves as having no computer skills (50% were interested in taking a computing skills course), advanced computer skills (45%), or expert computer skills (0%) (P<.001).
Type and Area of Practice
Physical therapists who identified pulmonary as their main area of practice were more likely to be interested in CAL than those practicing in other settings (OR=1.77, 95% CI=1.152.74, P=.008). Those who identified orthopedics as their primary practice were less likely to be interested in CAL than those respondents not practicing in that setting (OR=0.64, 95% CI=0.440.95, P=.025). For all other practice areas, the 95% CI for the OR contained the null value 1.0, indicating that respondents in those practice settings were not any more or less likely to be interested in CAL than respondents not practicing in those settings.36 Type of employer (private versus public) and type of work (full-time, part-time) were not related to interest in CAL (Tab. 2).
Geographic Distribution
The size of community and the time or distance required to travel to courses varied for respondents from different regions of the country (Tab. 3, Fig. 1); however, these factors were unrelated to interest in participating in CAL. To provide perspective to Figure 1, Canada is about 4,000 miles from the east coast to the west coast, with a population of approximately 31,500,000; only 4 of 9 Canadian metropolitan centers with a population greater than 500,000 are outside of southern Ontario and Quebec.10 Region of residence and size of community also were not related to interest in CAL (Tab. 2).

A continuing education study in British Columbia showed that 80% of physical therapists and occupational therapists indicated interest in Web programs or combined Web and face-to-face programs,15 which is similar to the finding among our sample of physical therapists from the cardiopulmonary special interest groups. In 1997, Tassone and Speechley9 found that CAL was ranked as the least interesting method of learning by physical therapists in Ontario compared with traditional modes of instruction (eg, face-to face courses). Although we did not compare CAL to other methods of instruction, the high interest in CAL in our sample may reflect the rapid increase in use of computers and increased exposure to user-friendly software and the Internet over the past 5 years, making physical therapists much more inclined to use computer and Internet technology in their education.
Interest in CAL and Computer Access and Skills
The finding that physical therapists who had more computer access were more likely to be interested in participating in CAL is similar to findings on other professional groups.37,38 In a survey of physicians in early 1995, 76.5% had access to a personal computer, but only 44.1% had access to CD-ROM drives and 36.3% had access to online services.38 A greater number of physicians with computer access or online access were interested in computer-assisted medical education than those without computer or online access.38 Since then, the use of CD-ROMs and the Internet has become more widespread, improving access to CAL. Consequently, it is likely that physical therapists with more computer access also will be able to take advantage of the convenience that CAL provides and participate in Web-based and CD-ROM courses that fit their schedule, when more CAL is available.
We found that respondents with novice, intermediate, and advanced computer skills were more likely than those without computer skills to be interested in CAL. Mamary and Charles39 recognized a lack of computer and Internet skills in a group of physicians as a barrier to participating in CAL. These authors suggested that computer instruction could be provided at conferences to promote the use of CAL in distance education. In our survey, respondents who rated themselves as having novice or intermediate computer skills were more interested in taking a course that would teach them the skills needed to engage in CAL than those who rated themselves as having advanced or expert computer skills. An introductory course may increase participants' comfort with using a computer and enhance their interest in taking continuing education using CAL methods. The level of computer literacy and comfort with newer technologies required for distance learning are more likely to exist in those people who graduated more recently.38 This may explain our finding that those respondents who graduated earlier (median of 1988) were less likely to be interested in undertaking CAL than respondents who graduated more recently (median of 1991).
Interest in CAL and Experience of CAL
Previous experience with CAL also may influence a person's interest in participating; however, we did not find that experience with CAL increased the likelihood that respondents would be interested in CAL. This may have been due to only a small number of respondents having prior CAL experience. Our results parallel the British Columbia needs assessment findings.37 Only a few respondents in each of these studies who expressed interest in Web-based learning had experienced it. The limited availability of CAL courses for physical therapists limits the opportunities that the therapists have to experience CAL or hear about it from others.
Interest in CAL and Geographic Distribution
The population of Canada is distributed more densely along the southern border of the country, in Quebec, Ontario, and western Canada (Fig. 1), and this distribution was reflected in the survey responses. Respondents living in less densely populated regions of Canada (ie, territories, eastern Canada, and northern regions of Quebec, Ontario, and western Canada) tended to report longer distances and time for travel to traditional "on-site" instruction. These factors have been shown to influence participation in continuing education activities.8,14 For example, those physical therapists living in the middle of the westernmost province of British Columbia would have a 10-hour drive to Vancouver where most of the physical therapy courses are offered in this province. Although CAL eliminates the time and expense associated with travel, the size of the community, region of residence, travel distance, and travel time were not related to interest in CAL in our study. At face value, this outcome was surprising but might reflect the fact that other factorssuch as experience with and access to technology, willingness to try something new, and family and employer supportmay be more important in influencing CAL participation than distance alone. The University of British Columbia (located in Vancouver) finding that 82% of students who take other online courses at this university are from the Vancouver area supports the contention that distance from a major center offering face-to-face courses is not the only factor associated with interest in participating in CAL.40
Interest in CAL and Area of Practice
Among our respondents, those who identified themselves as primarily practicing in orthopedics were less likely to be interested in participating in CAL than respondents who were not practicing in the orthopedic area. Those with pulmonary as their primary practice area were more likely to be interested in CAL than respondents who were not practicing in the pulmonary practice area. Because orthopedics comprises the majority of physical therapist practice in Canada,12 a large number of courses are offered in this area.13 A series of courses offered by the Orthopedic Division of the Canadian Physiotherapy Association provides a wide selection and availability of continuing education opportunities throughout Canada for physical therapists in orthopedics. The 1999 British Columbia continuing education study indicated that physical therapists acknowledged that these courses are primarily psychomotor (hands-on) and require onsite instruction.40 It is well recognized that Web-based learning is most suitable for acquiring and learning to apply new knowledge (ie, cognitive learning).32,41,42 Thus, the trend for physical therapists practicing in orthopedics to be less interested in participating in CAL may reflect the perceived nature of the knowledge and skills to be learned and the availability of existing continuing education.
The difference between physical therapists from the general licensing body and those in the cardiopulmonary interest groups also may be attributed to the type of content that can be taught using CAL methods (ie, hands-on orthopedic courses are not suited to CAL). When analyzed separately, however, the significant factors related to CAL were not different between the respondents from the cardiopulmonary interest groups and those from the licensing body.
Although the findings of this study indicate interest in CAL, this interest does not necessarily translate into enrollment into CAL courses. At present, the limited availability of CAL opportunities in physical therapy continuing education makes it difficult to predict with confidence the extent to which interest in CAL will translate into enrollment by physical therapists. Even if physical therapists are interested in CAL, a variety of factors are likely to influence decisions to take and complete a CAL course. Yoon43 suggested that, when selecting an online education course, adult learners most frequently ask "What is in it for me?" and "Will this work for me?" Although perceptions of efficiency and accessibility of CAL have been associated with enrolment,44,45 research is needed to determine the extent to which these and other factors related to student success in CAL prompt physical therapists to enroll in CAL courses.
Limitations
This survey did not attempt to differentiate between Web-based and CD-ROM learning but rather examined interest in undertaking any form of CAL for continuing education. Computer technologies provide different benefits for distance education. CD-ROM packages integrate text, animation, and video clips, providing a dynamic learning format.30 Web-based learning provides the added benefit of enabling interaction among people separated by distance, through e-mail, chat rooms, and bulletin boards.17,22,26 Future studies should examine the differential benefits and application of these formats in continuing education for physical therapists.
Test-retest reliability establishes the consistency of responses on 2 or more occasions.36 Measures of reliability provide an indication of the stability of the measurement over time and indicates whether the survey questions are being interpreted consistently. Although the test-retest reliability of data for this survey instrument was not evaluated, pilot testing was done to remove ambiguous items and ensure clarity of the survey questions as described in the Method section. This was done to ensure that respondents were interpreting the questions as intended by the authors.
Part 1 of the survey questionnaire provided examples of courses that were directed toward physical therapists with a special interest in the cardiopulmonary practice, and this emphasis may have influenced the results of parts 2 and 3. Although physical therapists in noncardiopulmonary practice may have interpreted the survey as being more related to cardiopulmonary practice than to their practice area, a reasonable response rate was obtained from the general, licensing body sample (50% response rate) and a large proportion of these physical therapists were interested in CAL (56.4%).
