Health coaching for promoting physical activity in low back pain patients: a secondary analysis on the usage and acceptance.

Background: Multicomponent interventions combined with health coaching are widely recommended to improve a healthy lifestyle. The aim of the present study was to analyse the usage and acceptance of a multicomponent intervention (telephone, web and face-to-face coaching) for low back pain patients, and thereby gain an understanding of why this intervention was not as effective as expected.

Methods: A secondary analysis of a randomised controlled trial, aimed at promoting physical activity, was conducted. It was a cross-sectional study based on data of a multicomponent intervention group (baseline = 201 participants). For evaluating the usage and acceptance, descriptive statistics were applied.

Results: Over half ( = 118) of the patients participated at least once in the telephone coaching. Approximately half of the participants (44 of 90) rated the telephone coaching as "good".34 of 92 (37%) participants reported of visiting the web-platform. The web-platform was comprehensible for nearly one-quarter ( = 8 of 33) and very useful for one participant.The face-to-face-contact was rated highly (range: 79.4-88.2 out of 100).

Conclusion: Usage of the telephone coaching approach was moderate with even fewer participants visiting the web-platform. In addition, these approaches were not rated as very useful. The acceptance of the face-to-face contact was high.Since the usage and acceptance could influence the effectiveness, utilisation and acceptance studies might help to explain the reason for non-effective lifestyle interventions. Therefore, more studies analysing the usage and acceptance are needed. To improve the usage and acceptance, a stronger participatory orientation in the design of interventions and the integration of face-to-face contact could be helpful.
