Abstract
Professionals within agricultural safety and health continue to seek effective methods to assist in guiding intervention activities. Recent use of behavioral psychology models has added insight into the beliefs and intentions of agricultural workers toward specific behaviors. This census study consisted of two phases. Phase one utilized the Theory of Planned Behavior to elicit the behavioral intentions, and the attitude, subjective norm, and perceived control (including underlying beliefs) of pork producers toward using respiratory protection while in confinement buildings in a specified situation. Phase two utilized the modal salient beliefs elicited in phase one to guide an intervention program consisting of group educational sessions and provision of a supply of two-strap toxic dust/mist respirators (tstd/mrs). Of specific research questions, two were (a) no difference would be seen between six-month intentions and self-reported behaviors (use) for any of the four quasi-experimental groups, and (b) six-month intention would contribute to prediction of self-reported behavior.
Both phase one and two utilized a pork producer association district, N = 342. This entire population received a mailed questionnaire in phase one and an educational session invitation in phase two. 184 responded to the questionnaire, and 80 attended an educational session. One-half of questionnaire respondents attending the educational session, and one-half of questionnaire respondents not attending the educational session were randomly assigned to receive tstd/mrs through the mail.
Phase one elicited salient beliefs that tstd/mrs (a) are hot and uncomfortable, (b) help to keep dust out of lungs, and (c) are difficult to keep where needed, and health professionals and spouses are motivating influences. Attitude and subjective norm contributed equally (w $\sim$.38) in the multiple correlation with intention.
Phase two findings indicated that current use of tstd/mrs nearly doubled and that frequency of use rose from quite unlike, to neutral (neither likely nor unlikely). Research Question 1 was not supported. All groups increased self-reported use over intentions. Research Question 2 was supported with the six-month intention substantially correlated with self-reported behavior, r =.52. The model used accounted for 28% of the variance in intention, indicating other contributing factors.
