Applying the theory of planned behaviour to understand mental health professionals’ intentions to work using a human rights-based approach in acute inpatient settings

Figures & data

Table 1. Example items in the theory of planned behaviour measure.

Generalised intention	I intend to support service users with mental health difficulties using a human rights-based approach
Direct measure of attitude	Supporting a service user with mental health difficulties using a human rights-based approach is: harmful/beneficial
Indirect measure of attitude + Outcome evaluations of attitude	Supporting a service user using a human rights-based approach will help to reduce stigma around their mental health difficulties Reducing stigma for a service user is: Extremely undesirable/Extremely desirable
Direct measure of subjective norm	People who are important to me want to support service users with mental health difficulties using a human rights-based approach
Indirect measure of subjective norm + Motivation to comply with norms	Senior managers would: disapprove/approve: of me supporting service users using a human rights-based approach What senior managers think I should do matters to me: not at all/very much
Direct measure of perceived behavioural control	Whether I support service users using a human rights-based approach or not is entirely up to me
Indirect measure of perceived behavioural control + Power of the factors	I feel equipped with the knowledge in how to use a human rights-based approach My knowledge in using a human rights-based approach makes me: less likely/more likely: to support service users with this approach

Table 2. Minimum values, maximum values, means and standard deviations from the theory of planned behaviour questionnaire.

Predictor variable (with range of scores)	Minimum	Maximum	Mean	Std. deviation
Direct ATT (1 to 7)	4	7	6.47	0.82
Indirect ATT (−105 to +105)	0	105	87.24	23.17
Direct SN (1 to 7)	2.75	7	5.21	0.90
Indirect SN (−189 to +189)	10	189	118.97	41.17
Direct PBC (1 to 7)	3	7	4.45	0.74
Indirect PBC (−42 to +42)	0	42	29.26	11.95
Intention (1 to 7)	4	7	6.54	0.71

ATT: attitude; SN: subjective norm; PBC: perceived behavioural control.

Table 3. Pearson product moment correlation coefficients for the three TPB predictor variables and intention.

	Subjective norm	Perceived behavioural control	Intention
Attitude	0.360**	−0.236*	0.695**
Subjective norm		0.044	0.462**
Perceived behavioural control			−0.211

* Correlation is significant at the 0.05 level; **correlation is significant at the 0.01 level.
