Nearly 40% of mortality in the United States is linked to social and behavioral factors such as smoking, diet and sedentary lifestyle. Autonomous self-regulation of health-related behaviors is thus ...an important aspect of human behavior to assess. In 1997, the Behavior Change Consortium (BCC) was formed. Within the BCC, seven health behaviors, 18 theoretical models, five intervention settings and 26 mediating variables were studied across diverse populations. One of the measures included across settings and health behaviors was the Treatment Self-Regulation Questionnaire (TSRQ). The purpose of the present study was to examine the validity of the TSRQ across settings and health behaviors (tobacco, diet and exercise). The TSRQ is composed of subscales assessing different forms of motivation: amotivation, external, introjection, identification and integration. Data were obtained from four different sites and a total of 2731 participants completed the TSRQ. Invariance analyses support the validity of the TSRQ across all four sites and all three health behaviors. Overall, the internal consistency of each subscale was acceptable (most α values >0.73). The present study provides further evidence of the validity of the TSRQ and its usefulness as an assessment tool across various settings and for different health behaviors.

This chapter outlines selected manual material handling activities and suggests a course of analysis to rapidly identify ergonomic issues and direct possible solutions. It presents a selection of ...analysis tools and related case studies and focuses on two broad categories of activities that nearly all soldiers experience: "lift-and-carry" and "push/pull." In the practice of human systems integration (HSI) within the US Army's acquisition community, the need to analyze manual material handling practices is frequently encountered. Proper ergonomic design is critical to minimize musculoskeletal injury risk, reduce fatigue, reduce required manpower, remove task specific personnel restrictions, and ensure maximum user–system compatibility. Manual material handling (MMH) is the use of human energy to perform physical tasks that may consist of lifting, lowering, pushing, pulling, carrying, and holding activities. M. S. Sanders and E. J. McCormick identify six categories of MMH risk factors: forceful exertions, awkward work posture, repetitive motions, sustained exertions, localized contact stresses, and whole body or segmental vibrations.

An ergonomic intervention of the construction of the Medium Girder Bridge was conducted. In this study, task observation, a sample survey, ergonomic assessment, and ergonomic intervention were ...conducted. Survey results were collected (n = 58), and served to identify the population and areas for ergonomic improvement. The revised NIOSH lifting equation and University of Michigan 3D Static Strength Prediction Program were then used to analyze manual materials handling tasks. By redesigning the hand tools used for bridge construction, the average NIOSH lifting index was decreased by 0.4 (−16%) and the average L5/S1 disc compression was reduced by 1700 N (−36%). These results along with other ergonomic improvements will be validated in a pending field study.
