Validation of a self-reported instrument to assess work-related difficulties in patients with migraine: the HEADWORK questionnaire.

ABSTRACT:

Background

The degree to which work-related difficulties are recognized in headache research is poor and often carried out with inadequate information such as "reduced ability to work as usual", which do not capture at all the variety of difficulties and the factors that impact over them. The aim of this paper is to present the validation of the HEADWORK questionnaire, which addresses the amount and severity of difficulties in work-related tasks and the factors that impact over them.

Methods

We developed a set of items based on a previous literature review and patients' focus groups and tested it on a wide set of patients with episodic and chronic migraine attending eight different Italian headache centers. HEADWORK factor structure was assessed with exploratory and confirmatory factor analysis; internal consistency and construct validity were addressed as well.

Results

The validation sample (N?=?373) was mostly composed of patients with episodic migraine without aura (64.3%) and of females (81%). Factor analysis retrieved two different scales: "Work-related difficulties", composed of eleven items which explain 67.1% of the total variance, and "Factors contributing to work difficulties", composed of six items which explain 52.1% of the total variance. Both HEADWORK subscales have good measurement properties, with higher scores being associated to higher disability, lower quality of life, lower productivity, higher headache frequency and pain intensity.

Conclusions

HEADWORK is a 17-item, two-scale questionnaire addressing the impact of migraine on work-related difficulties in terms of difficulties in general or specific skills, and the factors contributing to these difficulties, defined as negative impact on work tasks. It can be used to address disability weights for the purpose of calculating the burden of migraine, and to assess the balance between therapeutic and side effects of medication on productivity.

Project description:BACKGROUND:Work addiction is a significant public health problem with a growing prevalence. The Work Addiction Risk Test (WART) is the gold standard questionnaire to detect workaholism. OBJECTIVE:The main objective of this study was to validate the French version of the WART. METHODS:Questionnaires were proposed to voluntary French workers using the WittyFit software. There were no exclusion criteria. The questionnaire was administered anonymously for initial validity testing and readministered one week later for test-retest reliability. We also assessed the workers' sociodemographic characteristics, as well as other measurements for external validity, such as stress, well-being, and coaddictions to tobacco, alcohol, and cannabis. Several psychometric properties of the French-WART were explored: acceptability, reliability (internal consistency [Cronbach alpha coefficient] and reproducibility [Lin concordance coefficient]), construct validity (correlation coefficients and principal component analysis), and external validity (correlation coefficients). RESULTS:Among the 1580 workers using WittyFit, 187 (11.83%) agreed to complete the WART questionnaire. Of those, 128 completed the test-retest survey (68.4%). Acceptability found that all respondents had fully completed the questionnaire, with few floor or ceiling effects. Reliability was very good with a Cronbach alpha coefficient at .90 (internal consistency) and Lin concordance coefficient at .90 (95% CI .87-.94] with a difference on the retest of .04 (SD 4.9) (95% CI -9.6 to 9.7) (reproducibility). We identified three main dimensions (construct validity). Relationships between WART and stress and well-being confirmed its external validity. CONCLUSIONS:The French version of the WART is a valid and reliable instrument to assess work addiction with satisfactory psychometric properties. Used in occupational medicine, this tool would allow the diagnosis of work addiction and can be easily implemented in current practice.

Project description:BackgroundThe Strengths and Difficulties Questionnaire (SDQ) is widely used to screen for psychosocial problems among adolescents. As the severity of such problems is known to be related to age and gender, screening could be improved by interpreting SDQ scale scores with age-specific and perhaps gender-specific norms. Up to now, such norms are lacking. The aim of the current study is to present gender-specific and joint normative data per year of age for the Dutch self-reported and parent-reported SDQ versions for use among 12- to 17-year-old adolescents.MethodsThe norm groups for the self-reported and parent-reported SDQ versions consisted of 993 adolescents and 736 parents, respectively, from the general Dutch population. Per SDQ version, both gender-specific norms and joint norms (percentiles and cutoffs) per year of age were calculated through regression-based norming (Rigby in J Roy Stat Soc Ser C 54:507, 2005). Additionally, these norms were compared to the widely used British norms that are neither age-specific nor gender-specific.ResultsBy design, gender-specific 'abnormal' cutoffs (i.e., cutoffs aimed at identifying max. 10% of the most extremely scoring males and max. 10% of the most extremely scoring females) resulted in about equal percentages of 'abnormal' scoring male and female adolescents per SDQ scale. In contrast, joint 'abnormal' cutoffs (i.e., cutoffs aimed at identifying max. 10% of the most extremely scoring adolescents) resulted in relatively more male (7.6 to 13.6%, depending on age) than female (3.3 to 8.9%, depending on age) adolescents as scoring 'abnormal' on scales measuring externalizing behavior (self-reported and parent-reported SDQ versions), and relatively more female (3.9 to 14.3%, depending on age) than male (1.8 to 6.9%, depending on age) adolescents as scoring 'abnormal' on scales measuring internalizing behavior (self-reported SDQ version). In both types of norms, minor age effects were present. Among Dutch adolescents, the British norms yielded detection rates much lower than the expected 10%.ConclusionsOur findings indicate that detection rates depend on the reference group that is used (British or Dutch general adolescent population; specific gender group or not). The normative data in this paper facilitate the comparison of an adolescent's scores to different reference groups, and allow for cross-country/cultural comparisons of adolescents' psychosocial behavior.

Project description:ObjectivesGiven the lack of validated patient-reported outcomes (PRO) instruments assessing cold symptoms, a new pediatric PRO instrument was developed to assess multiple cold symptoms: the Child Cold Symptom Questionnaire (CCSQ). The objective of this research was to evaluate the measurement properties of the CCSQ.MethodsThis observational study involved daily completion of the self-report CCSQ by children aged 6-11 years in their home for 7 days. These data were used to develop a scoring algorithm and item-scale structure and evaluate the psychometric properties of the resulting scores. Analyses included evaluation of item and dimensionality performance (item response distributions and confirmatory factor analysis) and assessment of test-retest reliability in stable patients, construct validity (convergent and known groups validity), and preliminary responsiveness. Qualitative exit interviews in a subgroup of the children with colds and their parents were conducted.ResultsMore than 90% of children had no missing data during the testing period, reflecting an excellent completion rate. For most items, responses were distributed across the options, with approximately normal distributions. Test-retest reliability was adequate, with intra-class correlation coefficients ranging from 0.63 to 0.83. A logical pattern of correlations with the validated Strep-PRO instrument provided evidence supporting convergent validity. Single- and multi-item symptom scores distinguished between children who differed in their cold severity based on global ratings, providing evidence of known groups validity. Preliminary evidence indicates the CCSQ is responsive to changes over time.ConclusionsThe findings demonstrate that the CCSQ items and multi-item scores provide valid and reliable patient-reported measures of cold symptoms in children aged 6-11 years. They provide strong evidence supporting the validity of these items and multi-item scores for inclusion as endpoints in clinical trials to evaluate the efficacy of cold medicines.
