Development of the eTAP-T: A measure of mental health professionals' attitudes and process towards e-interventions

BACKGROUND: The development of technological applications within psychotherapy has opened up new opportunities for mental health professionals (MHPs) to address client need. Despite the clinical efficacy and utility of evidence-based electronic interventions, MHPs' engagement with these interventions remains poorly understood. OBJECTIVE: The aim of the current study was to develop and conduct a preliminary psychometric investigation of the measurement properties of the electronic-therapy attitudes and process questionnaire – therapist version (eTAP-T). Based upon the theory of planned behaviour (TPB), the eTAP-T measures factors related to MHPs' engagement with e-interventions for clients' mental health concerns. METHODS: Participants were 222 practicing MHPs who reported being in direct contact with clients. Participants completed the eTAP-T and related measures with a subsample of 40 participants completing a two-week follow up questionnaire. RESULTS: Exploratory factor analysis with item reduction resulted in a 12-item eTAP-T, with four factors accounting for 82% of variance. The four factors (subjective norms, perceived behavioural control, attitudes and intentions) were consistent with the four TPB domains. The eTAP-T demonstrated satisfactory validity and reliability as per the consensus-based standards for the selection of health measurement instruments. CONCLUSIONS: The development and preliminary psychometric investigation supported the validity and reliability of the eTAP-T. Further research is required for confirmatory analyses. The eTAP-T may be useful in identifying the training needs of MHPs and evaluating training programs. Specific areas for intervention, such as attitudes or perceived credibility may be identified and targetted, with the measure then also used to evaluate change across these domains. It is anticipated that the eTAP-T may useful tool in improving uptake of digital interventions by MHPs.
