The standardized Arabic Version (23 items) of the Pediatrics Asthma Quality of Life Questionnaire (PAQLQ) for children 7-17 years was also used.
Approval for using the standardized Arabic version of the PAQLQ and the PACQLQ was taken from the author.
Quality of Life as Assessed by PAQLQ. Poor quality of life is significantly related to impaired asthma control, as implied by the PAQLQ scores in our study.
In addition, all the three domains of the PAQLQ (activity, symptoms, and emotional function) were found to be equally affected.
The objective of our statistical analysis was to evaluate whether intervention assignment modified the preintervention-to-postintervention winter change in PAQLQ or peak flow measure.
In addition, to examine further whether impacts on health were consistent with changes in PM, we used linear mixed models to assess the effect of [PM.sub.2.5] concentrations on PAQLQ scores and peak flow measures.
PAQLQ measures the functional (physical, emotional, and social) problems that were most troublesome to asthmatics (23 questions in three domains [symptoms (5), activity limitation 2 generic (general), 3 patient-specific]) and emotional function (8).
Table 2 demonstrates that the mean overall PAQLQ score (3.27 [1.05]) was nearly similar to the score of symptoms, emotional function, and physical domain.
The overall PAQLQ score was the mean of all 23 responses and the individual domain scores were the means of the items in those domains .
The PAQLQ scores (total scores and score in each domain) showed significant improvement over the 12-week study period only in the asthmatic TCC group (p = 0.0004) (Table 2 and Figure 6).
There were also significant intercorrelations between the CASCL subscales and the PAQLQ. These intercorrelations indicate that the more a child appraises his or her asthma symptoms (e.g., panic/fear as "always being present" during an acute asthma episode), the lower the perceived health-related quality of life.
The PAQLQ is a self-report, health-related quality of life measure.
