Sleep disorder is a common professional hazard, particularly among IT professionals. But studies of it rarely consider the roles of psychological distress and work-family conflict. We apply the snowball sampling technique to collect data, and we use an integrated PLS-SEM method for factor analysis of sleep disorder. We employ a structured questionnaire to collect data. Results reveal that financial insecurity and job pressure among IT professionals significantly increase work-family conflict; job pressure and work contact contribute to psychological distress; sleep disorder is associated with both work-family conflict and psychological distress; and job autonomy and control reduces psychological distress. This study is novel in considering financial insecurity along with traditional constructs.
