The objective of this research was to assess the impact of a nutrition education intervention on intake of total ω-3 fatty acids (n-3 FA) in heart patients. The intervention design was a randomized trial comparing 2 interventions: decisional balance (DB) and no decisional balance (NDB). The outcome measures were total dietary n-3 FA intake and food sources. Intakes were measured using an n-3 FA...

BACKGROUND In many countries exercise prescriptions are used to facilitate physical activity in a sedentary population with or in risk of developing lifestyle diseases. Some studies show a positive effect of exercise prescription on specific lifestyle diseases. Others only show moderately positive or no effect on physical activity level. Furthermore, the challenge is adherence of participants t...

[Purpose] The purpose of this study was to identify the distribution of stages of change in the exercise behavior of university students the transtheoretical model. [Subjects and Methods] Study subjects at four universities in G city were surveyed. A total of 1,000 questionnaires were distributed, and 959 responses were analyzed. The collected data was analyzed using descriptive statistics and ...

A common question in perceptual science is to what extent different stimulus dimensions are processed independently. General recognition theory (GRT) offers a formal framework via which different notions of independence can be defined and tested rigorously, while also dissociating perceptual from decisional factors. This article presents a new GRT model that overcomes several shortcomings with ...

BACKGROUND As part of the process of developing a decision aid for carpal tunnel syndrome (CTS) according to the Ottawa Decision Support Framework, we were interested in the level of 'decisional conflict' of hand surgeons and patients with CTS. This study addresses the null hypothesis that there is no difference between surgeon and patient decisional conflict with respect to test and treatment ...

A great number of studies have been done on decision support systems. There is no work done on how a machine can intelligently help a decision maker in making appropriate choice for judgmental inputs for the decision support systems. Decisional guidance is a guidance for judgmental inputs while user is interacting with a decision support system (DSS). Traditionally the guidance provided by the ...

BACKGROUND Fertility patients often struggle with decisions about disposition of embryos remaining after fertility treatment. We aimed to identify predictors and correlates of decisional conflict among patients facing these decisions. METHODS We analyzed results from a survey of 2210 patients from nine geographically diverse US fertility clinics. The main outcome measure was decisional confli...

Face recognition is thought to rely on holistic processing, where the entire face is processed as a single unitary object. The nature of this holism is often assumed to be perceptual, however recent work applying the General Recognition Theory (GRT) framework suggests that holistic processing of faces may arise from decisional factors. Using Monte Carlo simulations, we examined how known violat...
