Study Description

Brief Summary:

The primary objective of study was to compare affective (i.e., highlighted emotional benefits), instrumental (i.e., highlighted other health benefits), and self-regulation (i.e., demonstrated ways to plan, set goals, etc.) interventions in terms of their ability to motivate less sitting in the workplace. Research of this type is important because people sit for long periods of time at work which adversely affects their health and productivity.

It was hypothesized that the affective and self-regulation groups would sit less than the instrumental and control groups based on evidence indicating that affective attitude (i.e., emotional evaluation of the behavior) and self-regulation techniques tend to predict behavior.

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: Nutrition condition; Received nutrition information such as the comparison of nutritional information between orange juice and soda pop. Received intervention following measurements at baseline, week 4, and week 8.	Behavioral: Nutrition condition; Received nutritional information in in-person PowerPoint presentations.
Experimental: Affective condition; Learned about the affective benefits (e.g., less depression) of reduced office sitting time through taking active breaks. Received intervention following measurements at baseline, week 4, and week 8.	Behavioral: Affective condition; Received information about affective benefits of less sitting in the workplace in in-person PowerPoint presentations.
Experimental: Instrumental condition; Learned about instrumental benefits such as the relationship between sitting and cardiovascular disease and absenteeism at work. Received intervention following measurements at baseline, week 4, and week 8.	Behavioral: Instrumental condition; Received information about instrumental benefits of less sitting in the workplace in in-person PowerPoint presentations.
Experimental: Self-regulation condition; Learned how to self-monitor their sedentary behavior and active breaks. They also learned how to create prompts/cues (e.g., sticky note reminder), problem solve to overcome barriers, action plan (i.e., specifying when, where, and how to do the behavior), and set goals in order to be less sedentary according to SMART (i.e., specific, measurable, attainable, relevant, time-oriented) principles. Received intervention following measurements at baseline, week 4, and week 8.	Behavioral: Self-regulation condition; Learned how to self-regulate behavior to sit less in the workplace in in-person PowerPoint presentations.
