چکیده مقاله :
هدف از پژوهش حاضر بررسی تأثیرسبک رهبری تبادلی سرپرست برآسیب‌های شغلی با میانجیگری هوشیاری ایمنی،گرانباری نقش و رویدادهای مرتبط با ایمنی بود. پژوهش رابطه‌ای از نوع مدل‌سازی معادلات ساختاری است. جامعۀ آماری پژوهش همۀ کارکنان شرکت ذوب آهن اصفهان در سال 1392 بودند که با روش نمونه‌گیری تصادفی طبقه‌ای 210 نفر به‌عنوان نمونه انتخاب شدند. ابزارهای پژوهش، مقیاس سبک رهبری تبادلی سرپرست (باس و آولیو، 1990)، مقیاس هوشیاری ایمنی (وستبی و لی، 2003)، مقیاس گرانباری نقش (بیهر، والاش و تیبر، 1976)، پرسشنامۀ رویدادهای مرتبط با ایمنی (بارلینگ و همکاران، 2002) و پرسشنامۀ آسیب‌های شغلی (بارلینگ و همکاران، 2002) بودند. تجزیه و تحلیل داده‌ها با استفاده از ضریب رگرسیون و مدل‌سازی معادلات ساختاری با کمک نرم‌افزار لیزرل انجام شد. برای آزمون معناداری مسیرهای غیرمستقیم از روش بوت استراپ در برنامه ماکروی پریچر و هایز (2008) استفاده گردید. یافته‌ها نشان‌دهنده تأثیرقابل قبول میان متغیرهای پژوهش بود (05/0P<). همچنین روابط غیرمستقیم سبک رهبری تبادلی برآسیب‌های شغلی با میانجی رویدادهای مرتبط با ایمنی، با میانجی هوشیاری ایمنی و رویدادهای مرتبط با ایمنی؛ و با میانجی گرانباری نقش و رویدادهای مرتبط با ایمنی مورد تأیید قرار گرفت (05/0P<).
The aim of the current study was to investigate the effect of transformational leadership style of supervisor on occupational injuries with the mediating role of safety consciousness, role overload and safety related events. The research was a correlational, structural equations modeling. The population consisted of all employees in Esfahan Steel Company in 2012. Through stratified random sampling 210 employees were selected. Research instruments were: Transformational Leadership Style Scale (Bass & Avolio 1990), Safety Consciousness Scale (Westaby & Lee 2003), Role Overload Scale (Beehr, Walsh & Taber, 1976), Safety-related Events Questionnaire (Barlingand et al., 2002) and Occupational Injuries Questionnaire (Barlingand et al., 2002). Data were analyzed by regression and structural equations modeling by LISREL software. To test the role of mediated effects, the Bootstrap procedure in the macro model of Preacher and Hayes (2008) was used. Findings revealed acceptable effects of all variables in the study (P<0.05). Also, the indirect effects of transactional leadership style on occupational injuries with mediating role of safety events; with mediating role of safety consciousness and safety events; and with mediating role of role overload and safety events were studied (P<0.05).
