vedenjske težave in učna uspešnost

some aspects of mother’s psychological functioning (mother → parenting →
self-regulation; Brody et al. 1994, 2002; Kim and Brody 2005).

Method for Longitudinal Study of Relations and Predictors
of Academic Achievement and Problem Behaviour
Participants
Children, whose parental informed consent had been obtained, were fol-
lowed for two years at four time points: upon starting the first grade (time
1; T1), upon finishing the first grade (T2), upon starting the second grade
(T3) and upon finishing the second grade (T4). Upon starting (T1) there
were 328 first grade students included in the study, aged between 69 and 89
months (M = 74.56; SD = 3.63), at time point T2 seven to eight months later
there were 325 (from 76 to 96 months; M = 82.72; SD = 3.67). At time point
T3 there were 324 second grade students, aged between 80 and 99 months
(M = 86.32; SD = 3.57) and at time point T4 eight months later 323. Almost
half of them (48%) were girls. At time point T1 there were 1 to 32 children
per school included in the study and 1 to 14 children per classroom. One
third of the children had never been enrolled into preschool, 35% were en-
rolled into preschool from the age of three and 31% from the age of one on-
wards. The stated characteristics of the sample group changed little during
the study.
The study included mothers (N = 320; from 6 to 23 completed years of
education; M = 12.48; SD = 3.06); 91% stated that their most frequently used
language at home was Slovenian. The research also included children’s class
teachers (N = 87) and their other teachers.

Instruments
The data was collected using the multi-reporter method (questionnaires
completed by the children’s mothers, class teachers and other teachers) and
individual tests (behavioural tasks) with the children.

Mother’s psychological functioning
LOT-R (Life orientation test – revised; Scheier, Carver and Bridges 1994) is
a 10-item self-report scale measuring individual differences in optimism.

RSES (Rosenberg self-esteem scale; Rosenberg 1989; The Rosenberg
self-esteem scale, n.d.) is a 10-item self-report scale measuring the global
dimension of self-esteem.
