As stated by Sobol-Shikler [12], the term affective state may refer to emotions, attitudes, beliefs, intents, desires, pretending, knowledge and moods.
This paper describes a behavioral model for affective social agents based on three independent but interacting parameter spaces: knowledge, personality, and mood.
Changes in diet and activity were regressed on knowledge and positive mood.
Because knowledge and positive mood were both assessed at time 2, this model assumed that the influence of the program on both was contemporaneous.
Examination of the pathways to lifestyle change showed that the educational aspect of the program increased activity levels because it increased diabetes knowledge and improved mood.
The final model was designed to compare the indirect effects of knowledge and positive mood on their unique ability to transmit the effects of the program to the change variables.
The effect of the program on change in activity was entirely indirect (0.08; P < 0.005), suggesting that the combination of knowledge and positive mood significantly mediated the effects of the program on activity.
Being in the program group rather than the control group was correlated with significant increases in healthy eating and activity, significantly greater weight loss and reduction in waist circumference, significantly greater readiness to change, exercise self-efficacy, diet self-efficacy, diabetes knowledge, and positive mood.
For patients who report difficulty paying for only selected medications, providers need to further probe beliefs about prescription drugs, medication knowledge, medication-specific concerns, and mood.
I will briefly review the current state of knowledge of circadian system and mood regulation, highlighting network properties and system dynamics as key mediators of neural plasticity, which underlies the circadian rhythm-mood connection.
