Table 4: Survey responses about location sharing (LS) and personal location-sharing devices (PLDs) for questions based on the Theory of Planned Behavior, with sample size (\(n\)) indicated in parentheses. Answer categories chosen by 50% or more of participants are highlighted in grey. Figure 3: Logger attitudes on outcomes associated with personal location-sharing device use: number of survey responses for different levels of likelihood (left) and value (right). Surveyed loggers indicated high perceived behavioral control, with 47.6% reporting having \"a lot\" of influence on whether PLDs are used within the company or organization, and only 17.2% stating no influence (Table 4, Section E). Loggers varied in their estimation of intent among other loggers (a measure of descriptive norms), but generally were either \"unsure\" about others' actions or predicted they were \"somewhat likely\" to adopt each of the safety practices (Table 4, Section B). Overall, loggers indicated an intent to use LS on their logging operations (Figure 4), and we rejected the null hypothesis that median scores were less than or equal to 3 (\"unsure\") with Sign and Wilcoxon Sign-Rank tests (Table 5). Intent was highest for using PLDs with local, automatic location sharing for hand fillers; 55.5% of respondents reported that they were \"somewhat likely\" or \"very likely\" to adopt this practice, with nearly one-third selecting \"very likely\" (Table 4, Section A). Similarly, half of loggers (51.4%) were likely to use PLDs on all ground workers and heavy equipment. Only about one-quarter of participants reported that they were unlikely to adopt the three behaviors. Internal consistency was high among the three safety practices ([PERSON]'s alpha of 0.84), suggesting that loggers may not have differentiated between the fine details of each practice. Based on ordinal regression, we failed to reject the null hypothesis that intent varies by age; however, the results indicated that intent does vary by the frequency with which loggers carry their smartphones during work activities, such that individuals who have their smartphone with them more often on logging operations are more likely to adopt the LS safety practices (Table 6). Age and phone use did not have significant interaction effects.
