Considerable evidence supports the efficacy of e-interventions for mental health treatment and support. However, client engagement and adherence to these interventions are less than optimal and remain poorly understood.
The aim of the current study was to develop and investigate the psychometric properties of the e-Therapy Attitudes and Process questionnaire (eTAP). Based on the Theory of Planned Behaviour (TPB), the eTAP was designed to measure factors related to client engagement in e-interventions for mental health.
Participants were 220 adults who reported current use of an e-intervention for mental health support. Participants completed the eTAP and related measures, with a subsample of 49 participants completing a one-week follow up assessment.
A 16-item version of the eTAP produced a clear four-factor structure, explaining 70.25% of variance. The factors were consistent with the TPB, namely, Intention, Subjective Norm, Attitudes, and Perceived Behavioural Control. Internal consistency of the total and subscales was high, and adequate to good one-week test retest reliability was found. Convergent and divergent validity of the total and subscales was supported, as was the predictive validity. Specifically, eTAP Intentions correctly predicted engagement in e-interventions with 84% accuracy and non-engagement with 74% accuracy.
The eTAP was developed as a measure of factors related to engagement and adherence with e-interventions for mental health. Psychometric investigation supported the validity and reliability of the eTAP. The eTAP may be a valuable tool to understand, predict, and guide interventions to increase engagement and adherence to e-interventions for mental health.
大量证据支持电子干预在心理健康治疗和支持方面的有效性。然而，客户对这些干预措施的参与度和依从性并不理想，且仍未得到充分理解。
本研究的目的是开发并调查电子治疗态度与过程问卷（eTAP）的心理测量特性。基于计划行为理论（TPB），eTAP旨在测量与客户参与心理健康电子干预相关的因素。
参与者为220名报告当前正在使用电子干预措施以获得心理健康支持的成年人。参与者完成了eTAP及相关测量，其中49名参与者的子样本完成了为期一周的随访评估。
16项版本的eTAP产生了清晰的四因素结构，解释了70.25%的方差。这些因素与TPB一致，即意图、主观规范、态度和感知行为控制。总量表和子量表的内部一致性较高，且发现了足够好的一周重测信度。总量表和子量表的收敛效度和区分效度均得到支持，预测效度也是如此。具体而言，eTAP意图以84%的准确率正确预测了对电子干预的参与情况，以74%的准确率正确预测了未参与情况。
开发eTAP是为了测量与参与和坚持心理健康电子干预相关的因素。心理测量学调查支持了eTAP的效度和信度。eTAP可能是一种有价值的工具，可用于理解、预测和指导干预措施，以提高对心理健康电子干预的参与度和依从性。
