[The use of guidelines for depression care in nursing homes in association with experienced competence, autonomy and relatedness by professionals].

Depression is highly prevalent in nursing homes residents and affects their quality of life. Both prevalence and impact of depression may decrease when effective guidelines or depression care programs are used, but this appears to be a challenging task. The Self Determination Theory postulates that the realization of complex tasks is being facilitated by meeting three basic human psychosocial needs: autonomy, competence and relatedness to others. This cross-sectional study investigates the relationship between the experienced autonomy, competence and relatedness and the extent to which depression care is given according to guidelines in 46 doctors, 49 psychologists and 53 nurses from 71 Dutch nursing homes. Although autonomy and competence were significantly related to depression care according to guidelines, hierarchical multiple regression analyses with all three basic needs showed a statistically significant result for competence only. The associations don't allow conclusions about causal relationships, longitudinal research will shed light on the direction of the association for competence.
