Questionnaires for the measurement of costs in economic evaluations

The impact of disease on the ability of a person to perform work should be part of an economic evaluation when a societal perspective is applied. iMTA is highly experienced in methods for measuring and valuing productivity losses. During the past years a number of questionnaires were developed for measuring productivity losses (respectively the Health & Labour Questionnaire, the Short Form-HLQ and PRODISQ) and several scientific papers were written on this topic including the valuation of productivity losses.

These questionnaires contributed to the development of the iMTA Productivity Cost Questionnaire  (iPCQ), bundling all relevant parts of the previously mentioned questionnaires into a short generic measurement instrument. Additionally, we developed a manual containing information on the modular structure of the iPCQ and it’s scoring- and valuation methods that are used for the cost calculations. The iPCQ  is a generic questionnaire and is applicable to national and international studies. Currently a Dutch version and an English version of the iPCQ are available. More translations are expected. For the measurement of productivity losses we prefer to apply the iPCQ in future studies.

The iPCQ may be combined with the iMTA Medical Consumption Questionnaire (iMCQ), a generic instrument for measuring medical costs.  The iMCQ includes questions related to frequently occurring contacts with health care providers and can be complemented with extra questions that are relevant for specific study populations.

Additionally, two questionnaires are available for measuring costs in patients with mental disorders. The recently updated TiC-P allows for the measurement of medical costs and productivity losses in adults with mental disorders.

iMTA has additionally developed a Parent-Form questionnaire for measuring medical and non-medical costs in children with mental health disorders, the TiC-P kinderen (in Dutch).

To improve the feasibility and reliability, all recently developed questionnaires were ‘translated’ into simple language by a specialized agency. Additionally, a feasibility study was performed to assess the comprehensibility of the questions in practice.

Permission for using the iMTA questionnaires can be requested by filling out the online registration form. We will respond on requests as soon as possible.

iMTA Valuation of Informal Care Questionnaire iVICQ

Many people provide support to a family member or friend in need of care. Lending this informal care may have a considerable impact on their life, in negative and positive ways. The overall effect on informal carers depends on the balance between these effects. Because the effects may be substantial and influence the ability of carers to persevere in their caregiving, it is pertinent that evaluations in health care take account of the impact of illness on the significant others of patients, in particular informal carers.

Researchers interested in measuring the impact of informal care and including informal care in economic evaluations of health care interventions can use the iMTA Valuation of Informal Care Questionnaire (iVICQ).
