Abstract

In understanding the safety climate or culture of a workplace, the perceptions and attitudes of the workforce are important factors in assessing safety needs. Safety solutions may fail if they do not take into account these prevailing attitudes and perceptions. Also, changes in attitudes and perceptions about safety are often likely outcomes of safety interventions. The aim of this study was to develop a measure of perception and attitudes about safety as an indicator of safety culture for use with working populations. After reviewing the structure and content of a number of older, related measures of safety attitudes, a 67-item questionnaire was developed. The questionnaire was distributed in a self-administered form to 1560 workers in a wide variety of types of jobs and 660 questionnaires were returned from 7 workplaces with a response rate of 42%. Items were evaluated by Cronbach alpha which showed that the item set shared considerable common variance. Scale development was approached in two ways. First items which were highly skewed were removed, resulting in removal of around half of the items, with very little loss in alpha. The remaining items were then subjected to factor analysis which revealed five factors; personal motivation for safe behaviour, positive safety practice, risk justification, fatalism and optimism. This factor structure showed acceptable psychometric properties. Second, in an effort to produce a unidimensional scale with a small, but representative set of items, additional items were removed which had high correlation with other items. This resulted in loss of around half of the remaining items. The short scale contained 17 items with again overall acceptable psychometric properties. The most striking finding in the development of this questionnaire was that there was little variation between respondents on a very large proportion of the questions originally selected. Clearly there are well-known beliefs about safety in the working community which need to be understood in order to progress the concept of safety culture.
