Multiple Additive Moderation Effects of Insufficient Job control, Lack of Reward, Self-efficacy in the Relationships between Job Demand on Mental Health among Non-regular Workers in South Korea: Using DRIVE model

Abstract

본 연구는 DRIVE모델을 이용하여, 비정규직 근로자의 직무요구가 정신건강에 미치는 영향을 확인하고 이 과정에서 직무자원인 보상부적절, 직무자율성 결여 및 개인자원인 자기효능감의 조절 효과를 검증하는데 목적이 있다. 조사대상자는 서울과 경기지역의 비정규직 근로자 333명이며, PROCESS Macro 프로그램을 활용하여, 다중가산조절모형을 검증하였다. 분석 결과, 첫째, 비정규 직 근로자의 직무요구는 정신건강에 부정적인 영향을 미치는 것으로 나타났다. 둘째, 직무요구와 정신건강과의 관계에서 자기효능감의 조절효과는 나타난 반면, 보상부적절의 조절효과는 나타나지 않았다. 셋째, 직무요구와 정신건강과의 관계에서 직무자율성 결여 및 자기효능감 모두 조절효 과를 보였다. 이러한 결과를 토대로 비정규직의 정신건강 향상을 위한 산업복지실천 프로그램의 필요성을 제안하였다.This study is to examine moderating effects of insufficient lack of reward, job control and self-efficacy in the relationship between effect of job demand on mental health of non-regular Workers based on the DRIVE model of Mark and Smith(2008). For this purpose, the participants are composed of 333 non-regular workers resided in Seoul and Gyeonggi-do, The PROCESS Macro program was used to examine the multi additive moderation model. The results are that first, the job demand were associated with mental health. Second, self-efficacy appeared to moderate the relationship between the job demand and mental health, but lack of reward did not. Third, both self-efficacy and insufficient job control moderated the relationships between job demands and mental health, which showed that multiple additive moderation effects were supported. Based on these results, there are need to develop the occupational social work practice program to improve the mental health of non-regular workers in South Korea.
