Bottom Line: The side effects and burden of anticoagulant treatments may contribute to poor compliance and consequently to treatment failure.No item was deleted or added after pilot testing as patients found the PACT-Q easy to understand and appropriate in length in all languages.Its validation and psychometric properties have been tested and are presented in a separate manuscript.

ABSTRACT

Background: The side effects and burden of anticoagulant treatments may contribute to poor compliance and consequently to treatment failure. A specific questionnaire is necessary to assess patients' needs and their perceptions of anticoagulant treatment.

Methods: A conceptual model of expectation and satisfaction with anticoagulant treatment was designed by an advisory board and used to guide patient (n = 31) and clinician (n = 17) interviews in French, US English and Dutch. Patients had either atrial fibrillation (AF), deep venous thrombosis (DVT), or pulmonary embolism (PE). Following interviews, three PACT-Q language versions were developed simultaneously and further pilot-tested by 19 patients. Linguistic validations were performed for additional language versions.

Results: Initial concepts were developed to cover three areas of interest: 'Treatment', 'Disease and Complications' and 'Information about disease and anticoagulant treatment'. After clinician and patient interviews, concepts were further refined into four domains and 17 concepts; test versions of the PACT-Q were then created simultaneously in three languages, each containing 27 items grouped into four domains: "Treatment Expectations" (7 items), "Convenience" (11 items), "Burden of Disease and Treatment" (2 items) and "Anticoagulant Treatment Satisfaction" (7 items). No item was deleted or added after pilot testing as patients found the PACT-Q easy to understand and appropriate in length in all languages. The PACT-Q was divided into two parts: the first part to measure the expectations and the second to measure the convenience, burden and treatment satisfaction, for evaluation prior to and after anticoagulant treatment, respectively. Eleven additional language versions were linguistically validated.

Conclusion: The PACT-Q has been rigorously developed and linguistically validated. It is available in 14 languages for use with thromboembolic patients, including AF, PE and DVT patients. Its validation and psychometric properties have been tested and are presented in a separate manuscript.

Figure 1: Refined conceptual model of the PACT-Q pilot version.

Mentions: Using the detailed concepts listed and based on patients' verbatim transcripts, three language versions (French, Dutch and US English) of the pilot questionnaire were created and validated, each containing 27 culturally equivalent items grouped into four domains: "Treatment Expectations" (7 items), "Convenience" (11 items), "Burden of Disease and Treatment" (2 items) and "Anticoagulant Treatment Satisfaction" (7 items) (Figure 1). No item was created for the detailed concepts about 'recovery', 'constraints (frequency of blood monitoring)', 'safe administration (mistakes in administration)', 'route of administration', and one single item was created for the concept 'impact of side effects, disease symptoms and blood monitoring on work and daily activities' since these detailed concepts were either covered elsewhere or qualified as a source of misunderstanding. Answers were designed according to 5-point Likert response scales. The questionnaire format was subsequently divided into two parts: the first part to measure expectations (7 items), to be administered before receiving treatment, and the second to measure convenience, burden and treatment satisfaction (20 items), to be administered after having received the treatment.
