The Spanish version of Occupational Balance Questionnaire: psychometric properties and normative data in a representative sample of adults

Abstract

Background The Occupational Balance Questionnaire (OBQ) is an instrument that assesses occupational balance (OB). It has been transculturality adapted and validated in different countries, showing adequate psychometric properties. To date, no general population-based cut-off points for OB have been developed.Objective To assess the psychometric proprieties of the Spanish version OBQ (OBQ-E) and to estimate reference norms and the cut-off for OBQ-E in a representative sample of Spanish adults.Materials and methods A total of 797 adults were included in this validity study. Internal consistency, intra and test-retest reliability of OBQ-E were examined. To obtain the convergent validity and the divergent validity, the Satisfaction with Life Scale (SLS) and the Hospital Anxiety and Depression Scale (HAD) were used respectively, compared with OBQ-E. To determine extreme and moderate disturbed OB stratified by age, sex, and educational level were used the 5 and 15% percentiles of OBQ-E.Results The OBQ-E showed good internal consistency (α-Cronbach = 0.87), intraclass reliability (ICC = 0.87), and test-retest reliability (rho = 0.83). Convergent (SLS) and divergent (HAD) validity were moderate (rho = 0.39 and rho = −0.46, respectively). The lowest extreme disturbed OB cut-off point in men (17.2) and in women (24) appeared at the primary education level, under 40 years of age (men) and 40–65 years of age (women).Conclusions The OBQ-E presents adequate psychometric properties, and its normative data can be used as a reference to assess and monitor the occupational balance in the general Spanish population.KEY MESSAGESThe ‘Occupational Balance Questionnaire’ (OBQ), stands out as a specific measure of the concept of Occupational Balance, considered as satisfaction with the number and variation of occupations in which the person participates.The OBQ is a short and simple instrument that can be a useful tool for use in population-based and epidemiological studies to monitor OB and explore the associated factors or implications of disturbed OB.The Spanish version of the OBQ (OBQ-E) seems to be a reliable and valid questionnaire to assess the perception of balance between occupations, related to health and well-being in the Spanish adult population.
