The aim of this study was to establish the comprehensibility and psychometric properties including internal reliability and criterion validity of the Depression, Anxiety and Stress Scale as a screening instrument for depression and / or anxiety in women with young children living in rural northern Vietnam.
However, all seek to build comprehensibility and trust by incorporating stakeholders as active participants in the modeling process: negotiating a shared conceptual framework, identifying data and information, examining and mitigating sources of bias, establishing appropriate contexts of use, and setting goals for verification and validation of the model's software and products.
To further establish the face-validity, comprehensibility and applicability of the interview items, six pilot ORACLe interviews were undertaken in three Australian health policy agencies followed by pilot testing of the SPIRIT intervention and the associated measurement tools (including ORACLe) in one policy agency.
The aims were to adapt the THP for rural Vietnam; establish the program's comprehensibility, acceptability and salience for universal use, and investigate whether administration to small groups of women might be of equivalent effectiveness to administration in home visits to individual women.
Gal and Prigat's [ 12] exploratory work emphasises the need to pre-test PILs to establish if there are readability and comprehensibility gaps, to appreciate the contextual element of PILs and the cognitive information processes involved in understanding PILs.
The pre-final version of the English, Afrikaans and Xhosa SA- PCS were tested among a second subgroup of subjects with fibromyalgia to establish face and content validity (acceptability and comprehensibility).
However, the initial stages of development and preliminary testing will be undertaken by the researchers including item generation and selection, establishing content validity, and testing comprehensibility to patients.
The Depression Anxiety and Stress Scale is a brief screening instrument, which is of particular value because it can assess multiple domains and is psychometrically sound in Anglophone and no-Anglophone settings, but its comprehensibility and psychometric properties in resource-constrained countries have not yet been established [ 8].
According to an established transcultural translation procedure [ 11], four criteria are evaluated at each qualitative research step: comprehensibility, acceptability, relevance, and completeness.
A study of the EIA detection tool on 39 patients with early inflammatory arthritis, 43 with established inflammatory arthritis, 50 with non-inflammatory arthritis musculoskeletal conditions, and 38 with non-musculoskeletal conditions demonstrated good comprehensibility, internal consistency, and test-retest reliability.
