Dyadic Asthma Management Questionnaire (DAMQ)

Abstract

The Dyadic Asthma Management Questionnaire (DAMQ; Heyduck-Weides et al., 2023) is a tool designed to measure perceptions of shared responsibility and collaboration in the management of asthma between adolescents and their caregivers. It includes both an adolescent version and a parallel caregiver version. The development of the DAMQ was guided by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) risk of bias checklist (Mokkink et al., 2018) and involved a combination of theory-driven and empirical approaches. Through a review of existing literature and semi-structured interviews with adolescents with asthma and their caregivers, 46 items were generated. These items cover two theoretical dimensions of the adolescent-caregiver partnership in asthma management: responsibility sharing and collaboration. Responsibility sharing assesses who is responsible for various management tasks, while collaboration addresses six key aspects, such as emotional support. Data for the DAMQ’s development were collected from adolescents with asthma and their primary caregivers in Germany. Both exploratory and confirmatory factor analyses, conducted for both the adolescent and caregiver versions, supported a 26-item structure representing three latent constructs in each version. The reliability, validity, and invariance of the DAMQ have been reported.

Purpose

The DAMQ was developed to identify adolescents’ and caregivers’ perspectives on asthma management, providing parallel adolescent and caregiver versions to capture both viewpoints.

Validity

Content Validity: The content validity of the DAMQ items was evaluated by a panel of consultants from the participating rehabilitation centers. This process led to the rephrasing of some items and revisions in the layout and instructions.
Construct Validity: Hypotheses testing for construct validity demonstrated correlations between the DAMQ scales and measures of juvenile asthma self-management (Short Self-Management Questionnaire for Adolescents with Asthma (KM-J-AB; Petermann et al., 2009), juvenile quality of life (DISABKIDS Chronic Generic Measure (DCGM-12; DISABKIDS Group Europe, 2006), and parental quality of life (Ulm Quality of Life Inventory for Parents of chronically ill children (ULQIE; Goldbeck & Storck, 2002). However, positive correlations with the KM-J-AB, which assesses actual asthma behavior over the preceding seven days, were only confirmed for the collaboration scales.

Reliability

Internal Consistency: For both the adolescent and caregiver versions of the DAMQ, the internal consistency, as indicated by values of Cronbach’s α, ω, and glb, was greater than 0.70 for all scales.

Factor Analysis

Exploratory Factor Analysis: For the responsibility sharing dimension, eigenvalues and scree plots suggested the same model for both adolescent and caregiver data, with items clustering around three interpretable factors. For the collaboration dimension, across both versions, scree plots indicated that three factors should be retained, covering three distinct aspects of parental collaborative involvement.
Confirmatory Factor Analysis: All model-fit indices achieved the threshold for acceptable fit (χ² = 361.3 [df = 270], p = 0.226; TLI = 0.91; CFI = 0.92; RMSEA = 0.06; SRMR = 0.07).
Measurement Invariance: Analyses of measurement invariance across different age groups revealed a good to excellent fit for adolescents aged 14 years and older, but a slightly poorer fit for adolescents younger than 14 years.

Instrument: Dyadic Asthma Management Questionnaire (DAMQ)

• Test Type: Original

• Format: The responsibility sharing items utilize a 5-point response scale where 1 = caregiver takes responsibility for this all of the time, 2 = caregiver takes responsibility for this most of the time, 3 = caregiver and adolescent share equal responsibility, 4 = adolescent takes responsibility for this most of the time, and 5 = adolescent takes responsibility for this all of the time. An additional option (0 = not needed) is available to indicate that a task does not apply to an individual adolescent’s asthma management. Collaboration items are scored on a 5-point scale, with 1 = never, 2 = rarely, 3 = sometimes, 4 = usually, and 5 = always. The administration method is paper-based.
