Cross-Cultural Adaptation and Psychometric Properties of Quality of Life Scales for Arabic-Speaking Adults: A systematic review

Psychometric properties of the Arabic Occupational Balance Questionnaire (OBQ11-A)

BACKGROUND

Occupational balance (OB) is a desirable outcome of rehabilitation because it is related to various health indices. The Occupational Balance Questionnaire (OBQ) is a self-report measure of occupational balance.

AIMS/OBJECTIVES

To examine the test-retest reliability, participant-level content validity, construct validity, internal consistency, and convergent validity of an Arabic occupational balance questionnaire (OBQ11-A).

MATERIALS AND METHODS

A total of 103 participants were recruited through convenience sampling. Test-retest reliability was examined using intraclass correlation coefficients, participant-level content validity using percentage of agreement in survey questions, construct validity using factor analysis, internal consistency using Cronbach's alpha, and convergent validity by examining associations with quality-of-life.

RESULTS

Intraclass Correlation Coefficient values for the total OBQ11-A scores and individual items were greater than 0.7 between the test and retest. The majority of respondents endorsed the relevance, comprehensiveness, and comprehensibility of the OBQ11-A. Cronbach's alpha for the OBQ11-A total score was 0.899. Nine of the 11 OBQ11-A items had factor loadings greater than 0.7. Moderate associations were found between the total OBQ11-A scores and physical health (n = 101; ρ = .52, p < .001), psychological health (n = 101; ρ = .49, p < .001), social relationships (n = 101; ρ = .36, p < .001), and environmental domains (n = 101; ρ = .57, p < .001) of the quality-of-life measure.

CONCLUSIONS

OBQ11-A demonstrates acceptable psychometric properties for research purposes.

Reliability and validity of cross‑culturally adapted oral health‑related quality‑of‑Life instruments for Brazilian children and adolescents: a systematic review

OBJECTIVE

This systematic review aimed to review the reliability and validity of oral health-related quality of life (OHRQoL) questionnaires for Brazilian children and adolescents. Also, the cross-cultural adaptation was evaluated.

METHODS

This systematic review is registered in PROSPERO (CRD42022300018) and was performed based on the COSMIN guideline. Electronic searches were performed in the PubMed/MEDLINE, Web of Science, Lilacs, BVS (BIREME), Scielo, and Embase databases until March 2023 by two independent reviewers. There was no restriction on time or language. The following studies were included: validation studies and cross-cultural adaptation of OHRQoL instruments into Brazilian Portuguese; studies that evaluated the measurement properties of OHRQoL questionnaires in children and adolescents and that reported at least one of the measurement properties: reliability, internal consistency, error measurement, content validity, construct validity, criterion validity, discriminant validity, and/or convergent validity. The following were excluded: studies of systematic reviews of OHRQoL measures; studies reporting OHRQoL assessment through instruments; construction (development) and validation of a new instrument; questionnaires that had a single item; and validation for Portuguese from Portugal. The cross-cultural adaptation process and psychometrics of the included studies were verified.

RESULTS

6556 articles were identified, and 19 manuscripts were included. All studies were conducted in Brazil, and the age of the participants ranged from 2 to 15.42 years old. Sixteen articles presented the cross-cultural validation steps. Cronbach's alpha of the revised instruments ranged from 0.59 to 0.86.

CONCLUSIONS

It can be concluded that most studies provided information and evidence regarding validity, reliability, translation, and cultural adaptation.

Psychometric assessment of oral health-related quality of life questionnaires cross-culturally adapted for use in Brazilian adults - a systematic review

OBJECTIVE

This study aimed to review the psychometric properties of oral health-related quality of life (OHRQoL) questionnaires for the Brazilian adult population.

METHODS

A systematic review was performed based on the COSMIN guidelines (PROSPERO CRD42022300018). The studies were obtained through electronic searches in the PubMed/MEDLINE, Web of Science, Lilacs, VHL (BIREME), SciELO, and Embase databases.

RESULTS

The search was performed in December 2022. Articles on OHRQoL that reported the cross-cultural adaptation of instruments into Portuguese (Brazil) and evaluated the psychometric properties of measuring instruments in adult patients were included. Those about the development of a novel instrument and participants under 18 years of age were excluded. Information was collected on the country, type of instrument validated, psychometric tests, and adaptation process. The certainty of the evidence was assessed using GRADEpro program. The search returned 6,556 articles, and 14 were considered for this review. However, two studies did not report the cross-cultural adaptation process. Content validity, internal consistency, criterion validity, construct validity, reliability, general discriminant validity, Cronbach's alpha value, and general intraclass correlation coefficient value were confirmed in 12 studies. Cronbach's alpha ranged from 0.69 to 0.96. The certainty of the evidence was considered moderate and low. This study has some limitations, such as the lack of information in some reviewed studies, the unavailability of Brazilian instruments, and absence of longitudinal validation of some instruments.

CONCLUSIONS

In conclusion, there are 14 OHRQoL instruments adapted for Brazilian adults that can be used with caution by researchers and clinicians, since they presented moderate to low certainty of the evidence.
