First, scores on adversity and the two mental health difficulties variables were divided into thirds, as used in other person-centred resilience investigations (e.g., see [ 126]).
There is limited information as to whether these differences are due to language or communication difficulties, variable knowledge and cultural attitudes to asthma or deficiencies of medical care.
Low and high adversity were defined as the bottom and top thirds on the cumulative adversity variable, and poor and good adjustment were defined as the top and bottom thirds of each SDQ mental health difficulties variable (as this was negatively scored).
The difficulties we found fell into five categories as listed in Table 1: the experimental subject itself (difficulty I), variables (difficulty II, A F), measures of experimental outcomes (difficulty III), dealing with variability (difficulty IV, A E), and interpreting experimental conclusions (difficulty V, A B).
To reduce the difficulty of variable selection, we can use valuable information from networks, each of which contains certain variables as nodes and represents their interactions.
Data from our undergraduate biology students permitted the reclassification of one partially established difficulty, the variable property of experimental subject, to established.
For emotional and behavioural difficulties, the variables included in the final model were bullying status (p=0.001), victimisation status (p=0.003) and hours of sedentary behaviour (p=0.002).
Those who avoid major motor impairment are well known to be at risk of adverse developmental outcomes, including, for example, cognitive difficulty of variable degree, impairments in attention and executive function 5 6.
The one partially established difficulty, concerning variable property of experimental subjects, had previously been identified in only one study by Salangam (2007) with undergraduate biology students who were not science majors.
