From: Proximal and distal predictors of self-regulatory change in children aged 4 to 7 years
Construct | Data source | Measure |
---|---|---|
Health & Health Behaviours | ||
Physical health | Parent | Physical Health Summary score from the Pediatric Quality of Life Inventory (PedsQL) [17]. Summed and average score of 8 items each rated on 5-point scale, tapping a child’s level of functioning in daily activities that rely on good physical health. E.g. problems with running. α = .72 |
Diet quality | Parent | Units of high sugar drinks consumed in the last week |
Behavioural sleep problems | Parent | Five items modelled as a latent variable as per prior studies [18]. E.g. child has problems on 4 or more nights a week with waking during the night (yes/no); this child’s sleep is a small/moderate/large problem. |
Development | ||
Receptive vocabulary | Assessed | Peabody Picture Vocabulary Test [19] of receptive vocabulary in which children listen to a spoken word and are asked to point to the matching picture given a set of four pictures. Higher scores represent higher receptive vocabulary skills. |
Gross motor development | Teacher | On a 4-point scale from ‘much less competent than peers’ to ‘more competent than peers’ |
Fine motor development | Teacher | On a 4-point scale from ‘much less competent than peers’ to ‘more competent than peers’ |
Pre-academic skills | Assessed | Who Am I test [20]. Children write their names, copy shapes, write words and numbers; scored according to skill level. α = .89 [21] |
Home environment | ||
Maternal parenting anger | Mother | Composite measure (weighted mean score) as per LSAC technical advice [22] using four adapted items from the National Longitudinal Study of Children & Youth [23]. Each item rated on 5-point scale from ‘never or almost never’ to ‘almost always’. E.g. how often are you angry when you punish this child? H = .72. |
Paternal parenting anger | Father | |
Maternal parenting consistency | Mother | Composite measure as per LSAC technical advice [22] using five items from the National Longitudinal Survey of Children and Youth [23]. Each item rates on a 10-point scale from ‘not at all’ to ‘all of the time’. E.g. how often does this child get away with things that you feel should have been punished? H = .80 for father; .82 for mothers. |
Paternal parenting consistency | Father | |
Maternal mental health | Mother | Kessler K6 screening scale [24] of six items (summed and averaged) about respondents’ feelings over the past four-week period. Rates on 5-point scale from ‘all of the time’ to ‘none of the time’. E.g. in the past 4 weeks how often have you felt hopeless? α = .84 for mothers, .82 for fathers. |
Paternal mental health | Father | |
Home learning environment | Parent | Single item book reading; plus latent variable with five indicators of other home learning activities including music, art, and play as used in other LSAC studies [25]. Each rated on 4-point scale of frequency of adult-child engagement for each activity in the last week from ‘not in the past week’ to ‘6–7 days in the week’. |
Financial hardship | Parent | 7-item count index ranging from 0 to 7, based on summing Yes = 1, No = 0 responses to 7 items including couldn’t pay bills, gone without meals as used in prior LSAC research [26]. |
Argumentative parental relationships | Parent | Composite of 5 items (summed and averaged) rated on a 5-point scale from ‘never’ to ‘always’. E.g. my partner and I argue; disagree over child-rearing etc. α = .80 |
Stressful life events | Parent | 13-item count index ranging from 0 to 13 based on summing Yes = 1, No = 0 responses about exposure to adverse life events over the past year including marital breakdown, death of friend, as per prior LSAC research [27]. |
Education | ||
Teacher-child relationship | Teacher | 8-item composite drawn from the Student Teacher Relationship Scale [28] following prior LSAC factor modelling [29]. Each item rated on 5-point scale from ‘definitely does not apply’ to ‘definitely applies’. E.g. share affectionate relationships, easy to be in tune with feelings α = .81 |
Time use | ||
Extra-curricular sport | Parent | Sum of 3 items indicating participation (yes / no) in extra-curricular swimming, gymnastics, or team sport |
Extra-curricular music / dance | Parent | Sum of 2 items indicating participation (yes / no) in extra-curricular music and dance |
Weekday TV hours | Parent | Number of hours watching TV on a typical weekday |
Weekday computer hours | Parent | Number of hours using a computer on a typical weekday |
Physical activity | Parent | Parent-rated child enjoyment of physical activity on a 5-point scale from ‘very much dislikes physical activities’ to ‘very much likes physical activity’ |
Neighbourhood | ||
Liveability | Parent | Composite (sum) of 8 items each rated on 4-point scale from ‘strongly disagree’ to ‘strongly agree’. E.g. this is a safe neighbourhood, this neighbourhood has good parks. α = .76 |
Socio-economic index for area (SEIFA) | Australian Bureau of Statistics | Composite of 31 variables (e.g. income, unemployment, occupation and education) computed by the Australian Bureau of Statistics [30]. |
