notes on the practical approach and nonverbal and verbal reactions of the respondent. Afterwards the respondents’ experience of the ease of use of the PSC was thoroughly discussed during an interview. The topic list of the interview contained: reading and comprehension level of the PSC, reasons for unanswered questions of the PSC and possible experienced emotional strain. To get more insight into the response process and the type of information that was generated by the questionnaire respondents were asked to formulate the PSC questions in their own words and describe how they went about answering them [32].

Furthermore, they were asked if they would appreciate it if their physical therapist would ask them to complete the PSC; and how they would value their physical therapist and treatment process if the PSC would be used.
Data analysis
After the audiotaped interviews were transcribed verbatim the data were analyzed using a thematic content analysis approach [35]. Researcher MW started with open coding, coding all fragments of all transcripts. To get more familiar with the data and to create an overview the researcher made a descriptive summary of each case after she finished open coding. Each summary contained all emerging themes regarding perceived ease of use of the PSC, the response process, the type of information that was generated through the PSC and perceived usefulness of the PSC. The emerged themes in the summaries were supplemented with related field notes, respondents’ demographics, self-proclaimed Dutch reading and writing skills, health literacy level and if applicable missing data and/or refusal of completing the PSC.
Then the researcher took an interpretative and inductive approach regarding perceived ease of use and perceived usefulness by listing emerging ‘themes’ from the descriptive summaries.
A more deductive approach was taken in order to identify problems that arose within the response process and information that was generated by completing the PSC which did not correspond to the intention of the PSC developers. Themes related to the response
