The relationship between perception of control and mood: The intervening effect of cultural values in a Saudi Arabian sample.

The relationship between the constructs of perceived control and symptoms of mood disorders has been demonstrated. The current study evaluates cultural values both as an individual difference moderating variable and as one of the mechanisms through which the association between perceived control and mood disturbances may operate. The hypotheses were examined with a sample of 615 participants recruited in Saudi Arabia. Participants completed measures of perceived control, individualism and collectivism, and symptoms of depression and bipolar disorder. In general, the results supported a model in which higher levels of perceived control promote a less symptomatic mood state. In most cases, cultural values positively mediated the relationship between perceived control and mood disturbance with lower symptom levels predicted. However, when the components of perceived control were examined separately, high perceived mastery together with highly individualistic values predicted higher levels of bipolar symptoms. In this sample, there was less evidence of cultural values moderating the control-mood disturbance relationship. Only one moderator relationship was identified, which showed low control linking to higher symptom levels only in those who disagreed with individualistic values. Overall, our data are in agreement with the notion that pre-existing cultural values have an important effect on mood disorder symptoms.
