Abstract null null Aims null Pain is the foremost complication to chronic pancreatitis (CP), but no validated questionnaires for assessment exist. The COMPAT questionnaire includes all relevant pain dimensions in CP, but a short form is needed to make it usable in clinical practice. null null null Methods null The full COMPAT questionnaire was completed by 91 patients and systematically reduced to six questions. Pain severity and analgesic use were merged, leaving five pain dimensions. The pain dimension ratings were normalized to a 0-100 scale, and the weighted total score was calculated, where three dimensions weighted double. Reliability of the short-form was tested in a test-retest study in 76 patients, and concurrent validity tested against the Brief Pain Inventory (BPI) and Izbicki pain questionnaire. Convergent validity was verified using confirmatory factor analysis, and criterion validity tested against quality-of-life and hospitalization rates. null null null Results null The COMPAT-SF questionnaire consisted of the following pain dimensions: a) pain severity, b) pain pattern, c) factors provoking pain, d) widespread pain, and e) a qualitative pain-describing dimension. Quality-of-life correlated with the total score and all pain dimensions (p null null null Conclusion null The COMPAT-SF questionnaire includes the most relevant aspects of pain in CP and is a feasible, reliable, and valid pain assessment instrument recommended to be used in future trials.

Abstract Background/objectives Chronic pancreatitis (CP) pain is challenging to treat. Treatment selection is hampered by there being no validated pain assessment tool that accounts for the complexity of CP pain and its underlying mechanisms. This study aims to develop a comprehensive pain assessment tool (COMPAT) specific for CP, evaluate its face validity with experts and patients and test it with a pilot cohort of patients. Methods COMPAT was developed from existing pain assessment tools and ...

AbstractObjectives: Chronic pancreatitis (CP) is a multifaceted disease associated with several risk factors and a complex clinical presentation. We established the Scandinavian Baltic Pancreatic Club (SBPC) Database to characterise and study the natural history of CP in a Northern European cohort. Here, we describe the design of the database and characteristics of the study cohort.Methods: Nine centres from six different countries in the Scandinavian-Baltic region joined the database. Patients ...

The task of developing a new questionnaire or translating an existing questionnaire into a different language might be overwhelming. The greatest challenge perhaps is to come up with a questionnaire that is psychometrically sound, and is efficient and effective for use in research and clinical settings. This article provides guidelines for the development and translation of questionnaires for application in medical fields, with a special emphasis on perioperative and pain medicine. We provide a ...

A popular trend has invaded applied psychometrics in terms of creating short forms for construct measures. There seems to be a paucity of developing methodologies for creating short forms based on complete forms that meet psychometric standards related to reliability of the scores and valid inferences. The present article suggests a methodology that rests on the fundamental assumption that the concept of short form attains meaning when being derived from valid scores of a complete form. A pivota...

Abstract Background Patients with chronic pancreatitis (CP) frequently report chronic abdominal pain that adversely impacts their quality of life. Assessment of pain in CP is required for clinical management and clinical studies. International consensus guidelines recognized a lack of specific and validated pain assessment tools for CP. Therefore, the aim of this systematic review is to identify and compare all clinical studies that assessed pain in the context of a treatment for pain in CP. Met...

### Key points The often complex, multidimensional, and subjective nature of pain makes it very challenging to assess both in terms of intensity and in terms of relief as a response to treatment. It is important for pain assessment in any setting to have scientifically valid tools to determine quality and intensity of pain, aid diagnosis, direct treatment, and evaluate effectiveness after discrete interventions. Valid, reliable, and sensitive tools are required to direct treatment for patient ca...

There is tremendous interpatient variability in the response to analgesic therapy (even for efficacious treatments), which can be the source of great frustration in clinical practice. This has led to calls for "precision medicine" or personalized pain therapeutics (ie, empirically based algorithms that determine the optimal treatments, or treatment combinations, for individual patients) that would presumably improve both the clinical care of patients with pain and the success rates for putative ...
Questionnaire is one of the most widely used tools to collect data in especially social science research. The main objective of questionnaire in research is to obtain relevant information in most reliable and valid manner. Thus the accuracy and consistency of survey/questionnaire forms a significant aspect of research methodology which are known as validity and reliability. Often new researchers are confused with selection and conducting of proper validity type to test their research instrument ...

Pain is the most common symptom in chronic pancreatitis (CP) with a major impact on quality of life. Few validated questionnaires to assess pain in CP exist, and the lack of consensus negatively impacts clinical management, research and meta-analysis. This guideline aims to review generic pain questionnaires for their usability in CP, to outline how pain assessment can be modified by confounding factors and pain types, to assess the value of additional measures such as quality of life, mental he...
