About this study

Official title: Expert System-Based Feedback in Sedentary Overweight Veterans

The purpose of the study was to examine the effectiveness of an expert-system, print-based physical activity (PA) intervention delivered to Veterans receiving primary care at the VA Pittsburgh Healthcare System (VAPHS).

Read the detailed description

A.1 The primary aim of the study was to determine the effect of a physical activity intervention designed to increase physical activity for sedentary Veterans at VAPHS.

A.2. Secondary aims were to assess key health-related outcomes related to the intervention including health and quality of life. The specific outcomes were to (a) estimate the impact of the intervention on physical function, health-related quality of life (HRQL), weight, blood pressure, and serum lipids; and (b) characterize variation in intervention effectiveness by participant sociodemographic and health characteristics, such as age, race, and baseline health status.

232 Veterans were randomized to either the physical activity intervention group or the attention control group. Participants randomized to the physical activity intervention group participated in an individualized physical activity counseling session at baseline, conducted by an exercise physiologist, with guided goal setting to increase physical activity gradually to at least 150 minutes/week of moderate intensity. An additional 14 intervention counseling contacts, generated by participants' responses to physical activity questionnaires and individually tailored computer-generated expert system feedback messages based on stages of the motivational readiness for change model, were conducted via postal mail over the subsequent 12 months in parallel with routine primary care. Newsletters providing additional support and suggestions for increasing physical activity were also part of the mailed counseling contacts. Participants randomized to the attention control group participated in a generalized healthy lifestyle counseling session at baseline, conducted by a health educator, which included limited advice to become more physically active. Fourteen follow-up wellness newsletters that focused on healthy lifestyle issues other than physical activity were sent to participants via postal mail over the subsequent 12 months with the same frequency of contact as for the physical activity intervention group and in parallel with routine primary care. Assessment of effectiveness occurred at baseline, 6, and 12 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Expert system-based physical activity counselingBehavioural

    The intervention included 14 mailings to participants that involved completion of physical activity questionnaires printed on forms that were scanned into a computerized expert system program to generate individually-tailored feedback messages and related manuals based on the Stages of Motivational Readiness for Change Model. Newsletters providing additional support and suggestions for increasing physical activity were also part of the mailing program.

  19. Health Related Quality of Life (HRQL): Short Form 36 Health Survey Questionnaire (SF-36) Physical Component Summary Measure (PCS)

    HRQL: SF-36 PCS measured at Month 0. The SF-36 is a multi-purpose, short-form health survey with 36 questions. It yields an 8-scale profile of functional health and well-being scores as well as psychometrically-based physical and mental health summary measures and a preference-based health utility index. The 8 scales are the weighted sums of the 2-10 questions in their section. Norm-based scoring, where each scale and component summary measures were scored to have the same average (50) and the same standard deviation (10 points), was used for reporting results in this study. Scores are interpreted as the lower the score the more disability; conversely, the higher the score the less disability. The PCS aggregates the scales for bodily pain, general health perceptions, physical functioning, and role limitation due to physical health problems.
