“…Also, our sample showed an overrepresentation of parents with higher education and Swedish-born parents and children compared with the total population. On the other hand, the employment rate of 86% was approximately equal to the 85% in the total population (40). Also, parental QoL was approximately equivalent to levels in Norwegian and Danish population samples, where WHOQOL-BREF studies have been conducted (27,41).…”

Background: The Strengths and Difficulties Questionnaire (SDQ) measures behavioral problems among children and adolescents. Prior research in Sweden has included child self-report or parent ratings from community or population data. Objective: To provide child-reported and parent-rated SDQ norms for 11-to 16-year-olds, as well as data on child-parent agreement and parental sociodemographic correlates: education, employment status, and quality of life. Method: A random population sample with 600 children aged 11 to 16 years, 100 per age group, and one of their parents (N=1200) yielded a sampling pool of 1158 participants and a 34.8% response rate, including 175 child-parent pairs and 27 and 26 child/parent singletons. Responses to child and parent versions of the extended SDQ were analyzed by child gender and age. Child-parent agreement was evaluated using the Prevalence-and Bias-Adjusted Kappa and Bland-Altman plots. Results: Older children reported greater difficulties compared with younger children, while girls reported a higher negative impact of difficulties on daily life in comparison to boys. Child-parent item-by-item agreement was fair to slight on 15 of the 25 SDQ items, perfect to moderate on 9 items, and less than chance on 1 item, but generally high regarding dichotomous assignment to the "raised difficulties" or "normal" groups, based on subscales and the total SDQ score. Greater difficulties for children were reported by parents born outside Sweden, parents of children born outside Sweden, parents lacking regular employment, and parents with lower education or lower quality of life. In relation to other child-parent pairs, parents born outside Sweden perceived greater difficulties for their children compared with the children's own ratings. Parents with better physical health and social relationships rated their children as having fewer difficulties compared with the rates reported by children. Conclusions: Gender differences contrasted with prior Swedish studies showing higher ratings for boys on hyperactivity and total difficulties and for girls on emotional symptoms. However, findings on increased difficulties with age concurred with prior studies. Research on children's mental health should be widely and systematically conducted at regular intervals and encompasses large, representative samples in order to inform national public health and health-care policy regarding measures to support children and enhance their mental health.

“…However, the measurement properties of the WHOQOL-BREF have rarely been explored using modern test theory (e.g., Rasch analysis). In a recent study of the WHOQOL-BREF [7], the item responses to the 5-point rating scales were dichotomiedso that the dichotomous Rasch model could be fitted. Dichotomizing responses will in general cause a loss of information and lead to less accurate measures.…”

Validating, Improving Reliability, and Estimating Correlation of the Four Subscales in the WHOQOL-BREF using Multidimensional Rasch Analysis

Objective: This study examined the construct validity, and improved the test reliability and the estimation accuracy for the correlation between domains of the WHOQOL-BREF using multidimensional Rasch analysis. Method: A total of 13,083 adults were administered the 28-item WHOQOL-BREF Taiwan version, which consists of 4 subscales (domains). The multidimensional form of the partial credit model was used to examine the fit of the 4 subscales. For comparison, each subscale individually was also fitted to the unidimensional partial credit model. Standard item fit statistics and analysis of differential item functioning (DIF) were used to check model-data fit. Results: After excluding 2 overall items and deleting 7 DIF items, the remaining items of each subscale in the WHOQOL-BREF constituted a single construct. The test reliabilities and correlations between domains obtained from the multidimensional approach, (0.82-0.86) and (0.79-0.89), respectively, were much higher than those obtained from the unidimensional approach, (0.67-0.75) and (0.53-0.65), respectively. Conclusion: The 19-item WHOQOL-BREF measures more succinct latent traits than the original design. The multidimensional approach yields not only more accurate estimates for the correlation between domains but also substantially higher reliabilities, than the standard unidimensional approach.
