چکیده مقاله :
هدف این پژوهش، بررسی نقش واسطه‌ای عزت‌نفس سازمان محور در تأثیر گرانباری نقش، تعارض نقش و ابهام نقش بر عملکرد وظیفه‌ای و رفتار شهروندی سازمانی بود. نمونه‌ی پژوهش، 213 نفر از کارکنان شرکت ملی حفاری ایران بود که با استفاده از نمونه‌گیری تصادفی ساده انتخاب شدند. در این پژوهش، از پرسشنامه‌های استانداردی هم‌چون ارزشیابی سازمانی میشیگان (Michigan Organizational Assessment, 1969)، تعارض و ابهام نقش (Rizo, Hose, & Lirtzman, 1970)، عملکرد شغلی (Williamz & Anderson, 1991)، رفتار شهروندی سازمانی (Podsakoff, MacKenzie, Morrman, & Fetter, 1990) و عزت‌نفس سازمان محور (Pierce, Gardner, Cummings, Dunham, 1989) و برای تجزیه‌وتحلیل داده‌ها از روش تحلیل مسیر استفاده شد. آزمون الگوی پژوهش نشان دهنده برازندگی قابل قبول الگو بود. بررسی تأثیرات مستقیم نشان داد که ابهام نقش تأثیر منفی و معناداری بر عملکرد وظیفه‌ای (01/0p<)، رفتار شهروندی سازمانی (05/0p<) و عزت‌نفس سازمان محور دارد (01/0p<) و عزت‌نفس سازمان محور تأثیر مثبت و معناداری بر عملکرد وظیفه‌ای و رفتار شهروندی سازمانی دارد (01/0p<). هم‌چنین، آزمون تأثیرات غیرمستقیم نیز نشان داد که عزت‌نفس سازمان محور نقش واسطه‌ای در تأثیر ابهام نقش بر عملکرد وظیفه‌ای و رفتار شهروندی سازمانی دارد (05/0p<). ازاین‌رو به مدیران توصیه می‌شود که با به‌کارگیری راهکارهای مناسب، ابهام نقش را کاهش و عزت‌نفس سازمان محور کارکنان را ارتقا دهند تا از این طریق، عملکرد شغلی و رفتار شهروندی سازمانی آنان نیز افزایش یابند.
