 posure or respondent strategy, in order to which dysfunctional IPs, the therapist aimed to intervene on, was not made transparent. Hereby, the reproducibility the study Concerning the selection of the treatment strategy was hampered. So, in further research we would like to focus on the treatment validity of the intervention. Hereby it makes the understanding on when to choose which strategy more feasible.
Further, we choose to analyse our data by using a linear mixed model with repeated meas- ures. This is not in line with the recommendation by SCED guidelines. The reason for our choice is that more robust results can be presented with linear mixed model analysis on the mediation and moderation effect of IPs, besides visual analysis as recommended by SCED guidelines.
Practical implications
An important finding of this study is that baseline IP Personal Control moderates the physi- otherapy treatment effects. For daily practice we advise physiotherapist therefore to assess patients’ baseline beliefs on how they feel they are in control of their MSK pain. This can be easily assessed by the third question of the Brief IPQ-DLV. A low, non-converted, score on this IP dimension (3 or less on 0-10) can be used to design a part of a matched care with the goal of improving patients’ controllability of their MSP.
Furthermore, to monitor the IP dimensions Consequences, Personal control, Identity, Con- cern and Emotional Response during treatment can be advised for their mediation effect on treatment outcome.
Overall, the conclusions that can be drawn from the third theme of this thesis are:
• The IPs dimension Personal Control moderates the outcome of a matched care physio- therapy treatment. So, it is worthwhile to address patients’ Personal Control beliefs at
baseline and if dysfunctional, alter it to a more functional perception.
• The IP dimensions Consequences, Personal Control, Identity, Concern and Emotional Re- sponse had a mediation effect and therefor are recommended to be incorporated during physiotherapy treatment to alter them from dysfunctional to more functional percep-
tions.
• Further research is needed to explore which modalities of a physiotherapy intervention
are best to use for altering dysfunctional perceptions. In addition, intervention studies with control groups on the effect of a marched care physiotherapy intervention to alter dysfunctional perception is recommended.
