Abstract
This project studied the effect of a self-instructional slide-tape program upon dietary knowledge and dietary compliance of renal patients on dialysis. The study was comprised of two parts. The first part involved the development of the slide-tape program. The second part dealt directly with the research problem. During this phase, the slide-tape program was presented to the renal patients while on dialysis and data were collected to determine the effect of the program upon dietary knowledge and dietary compliance.
The slide-tape program, based on accepted renal diet therapy, was composed of two 14-minute segments and was accompanied by individual study guides. The first segment discussed the role of
the kidney and the requirements for protein and kilocalories. The second segment discussed the need for potassium, sodium and fluid and the hazards of excesses of these nutrients. Partway through
each segment and at the end of each segment, patients were presented true-false questions. The answers appeared immediately following the questions.
The target population consisted of 26 renal patients who were receiving dialysis therapy on an out-patient basis at St. Paul's Hospital in Saskatoon. Patients in the treatment group (n=14) completed pre and post tests and viewed the slide-tape program. The control group (n=12) completed pre and post tests and did not view the slide-tape program.
Data were collected from April until November, 1979. Data collection instruments included (1) pre and post dietary knowledge questionnaires, (2) pre and post 7-day food records and (3) pre and post biochemical measurements (weight gained between dialysis, predialysis serum potassium, and predialysis serum urea). The pre and post tests were analyzed to determine significant differences between the treatment and control groups. Results indicated that the self-instructional slide-tape program did not significantly increase dietary knowledge or improve dietary compliance of the study subjects (p=0.05).
Variables of interest in the study were analyzed. The mean age of the sample was 44.73 years. The sex distribution of the sample was 35% male and 65% female. The greatest proportion of study subjects, 46% of the sample, reported an educational level of grade 10-12. The cause of renal failure was primarily glomerulonephritis (46% of the sample), with polycystic kidney disease and interstitial
nephritis being the second and third most common causes of renal failure in study subjects (18% and 8% of the sample, respectively). Subjects were questioned about prior dietary instruction with the
dietitian. The sample averaged 4 meetings and 2.40 hours with the dietitian. The average length of time of dialysis therapy for the sample was 14.73 months.
Although the research study did not demonstrate significant effects of the slide-tape program on dietary knowledge and dietary compliance, its value as an educational tool remains. Evidence exists
that the slide-tape program may benefit individuals having had no previous dietary instruction. In addition, the slide-tape program has several advantages including self-presentation, standard
presentation and availability. The slide-tape program can be a useful addition to renal diet education programs
