Attitudes that determine willingness to seek psychiatric help for depression: a representative population survey applying the Theory of Planned Behaviour

Many people suffering from mental disorders do not seek appropriate help. We have examined attitudes that further or hinder help-seeking for depression with an established socio-psychological model, the Theory of Planned Behaviour (TPB), comparing models for respondents with and without depressive symptoms. A qualitative preparatory study (n=29) elicited salient behavioural (BB), normative (NB) and control beliefs (CB) that were later included in the TPB questionnaire. Telephone interviews with a representative population sample in Germany (n=2303) started with a labelled vignette describing symptoms of a major depression, followed by items covering the components of the TPB. Intention to see a psychiatrist for the problem described was elicited at the beginning and at the end of the interview. We screened participants for current depressive symptoms using the mood subscale of the Patient Health Questionnaire (PHQ-9). In non-depressed respondents (n=2167), a TPB path model predicted 42% of the variance for the first and 51% for the second question on intention. In an analogous model for depressed respondents (n=136), these values increased to 50% and 61% respectively. Path coefficients in both models were similar. In both depressed and non-depressed persons, attitude towards the behaviour was more important than the subjective norm, whereas perceived behavioural control was of minor influence. Willingness to seek psychiatric help for depression can largely be explained by a set of attitudes and beliefs as conceptualized by the TPB. Our findings suggest that changing attitudes in the general population are likely to effect help-seeking when people experience depressive symptoms.
