Abstract
This study aims to find the impact on suicidal thought of the quality of sleep and depression of college students using an structural equation model. Especially this research focus on whether or not the quality of sleep have an direct or indirect influence on suicidal thought in terms of 5 factors of depression which are negative emotion, personal elation/sorrow, personal elation/sorrow, sense of failure, loneliness, melancholy feeling. As the result of the structural equation model selected, the low quality of sleep had positive effect on negative emotion, personal elation/sorrow, personal elation/sorrow, sense of failure, loneliness, melancholy feeling which are the factors of depression. And only two factors of depression such as sense of failure and negative emotion affected suicidal thought. However the low quality of sleep did not directly affect suicidal thought but indirectly affected it in terms of factors of depression.
