Interrelationships between dissatisfaction with teaching work and depressive symptoms: Structural equation modelling

The objective of this article is to evaluate the interrelationships of factors associated with depressive symptoms (DS) in teachers, considering dissatisfaction with the teaching job as a possible mediator. This was a cross-sectional study using data from 700 teachers from the public school system of a Brazilian municipality. The outcome of interest was DS, as assessed using the Beck Depression Inventory (BDI). Direct and indirect interrelationships between the outcome and dissatisfaction with work, age, income, lifestyle and adiposity were tested. These variables composed the operational model tested by structural equation modelling. Older age (β=0.12) and greater dissatisfaction with work (β=0.12) were directly associated with DS. A more favourable lifestyle (β=-0.60) and adiposity (β=-0.10) were associated with a lower occurrence of DS. The variables lifestyle (β=-0.06) and adiposity (β=-0.02) also had negative indirect effects on DS, mediated by job dissatisfaction. The structural equation model tested identified interrelationships that influenced DS. Dissatisfaction with teaching work was associated with DS and mediated the relationship of other factors with such symptoms.
