This study compared two commonly used screening scales, HADS and DASS, in relation to their measurement range and cut points to consider if prevalence rates may be due to scale-specific case definition.
By co-calibrating the items from both scales onto a single metric the three constructs, depression, anxiety and stress, will be mapped to: (a) compare the range of DASS depression and anxiety to that of the HADS scales; and (b) compare the two scales' cut points for depression and anxiety to determine if any variability may be due to scale-specific case definition.
This study compared two commonly used scales, the Depression Anxiety and Stress Scale (DASS) and the Hospital Anxiety and Depression Scale (HADS), in relation to their measurement range and cut points to consider the relative prevalence of both constructs, and if prevalence rates may be due to scale-specific case definition.
The most costly design and operation problems in seawater desalination are due to scale formation and corrosion of plant equipment.
Thirdly, beyond these seaports, Aveiro seaport turns out efficient when BCC model is applied, indicating that its dominant source of inefficiency is due to scale efficiency.
Therefore, when a DMU is inefficient in CCR models and turns out to be efficient in BCC models, signifying that the dominant source of inefficiency is due to scale efficiency.
Future work should attempt to determine whether this difference in control performance is due to scale free networks being inherently more difficult to control, or due to the fact that larger variation in node properties in scale free networks requires more specific control sets to be selected (again, these results are aggregated across each possible set of controllers).
Previous research among patients with SCI revealed that for some patients the change over time in satisfaction with life -measured with a likert-scale- was due to scale recalibration [ 24].
