Further Validation of the Norwegian Self-Efficacy for Therapeutic Mode Use

Background. The Intentional Relationship Model (IRM) proposes six therapeutic modes as ways of relating to clients. The Norwegian self-efficacy for therapeutic mode use (N-SETMU) was found to have a one-component structure. However, its items reflect abstract concepts rather than concrete behaviors. Aim. To validate further the N-SETMU by linking its items to the Norwegian client assessment of modes (N-CAM), with 30 items constituting six scales (linked to each mode), possessing concrete, behavioral content. Methods. Occupational therapy students () completed the N-SETMU and the N-CAM derived items, along with sociodemographic information. Component structure was analyzed with Principal Components Analysis (PCA), internal consistency of scales with Cronbach's α, and associations between scale scores with Pearson's . Results. All items on all N-CAM derived scales loaded on one latent component, except one item related to problem-solving. After removing this item, the scale functioned appropriately. Cronbach's α for all N-CAM derived scales ranged 0.88–0.94, and the associations between the N-CAM derived scales and the corresponding N-SETMU items ranged between 0.60 (advocating) and 0.79 (encouraging). Conclusions. In view of the strong associations between the concrete, N-CAM derived scales and the abstract N-SETMU items, this study supports the concurrent validity of the N-SETMU.
