Latent classes of psycho-behavioural adaptation among children
Five models were estimated during exploration. The second-class model was identified as the best-fitting one due to its small AIC, BIC, and aBIC and significant LMRT P value, as well as BLRT P value. When we compared the second-class and third-class models, the BLRT P value and LMRT P value were non-significant, indicating that the third-class model was not better than the second-class model. The model fit statistics for latent class estimation are shown in Table 1.

Features and name of each latent class
Each class was named based on five dimensions: emotional symptoms, conduct problems, hyperactivity and attention disorders, peer interaction problems, and pro-social behaviour (Fig. 1). According to a previous study, values of ≥ 0.60 was considered as high probability, with values of < 0.60 and ≥ 0.15 moderate probability, and values of < 0.15 low probability(Burstein et al., 2012).
Class 1 (n = 39, 16.12%) children had high conduct problems and emotional symptoms, with moderate levels of hyperactivity and attention disorders, peer interaction problems, and pro-social behaviour; therefore, this class was named the psycho-behavioural problem group.
Class 2 (n = 203, 83.88%), children's emotional symptoms, conduct problems, hyperactivity and attention disorders, and peer interaction problems dimensions were at low levels, while pro-social behaviour was at moderate levels, naming this class as the psycho-behavioural health group.
Sociodemographic characteristics of latent classes
The differences in sociodemographic factors in each class were shown in Table 2. Regarding child's gender, parental roles, parental age, parental educational level, monthly income, and marital status, there was no difference between those two classes. However, as to the parental health aspect, parents with poorer health were more likely to be in the psycho-behavioural problems group (ꭓ2=8.81, P < 0.05). Those aged 3–6,7–12 years showed progressively higher proportions in the psycho-behavioural health group (ꭓ2 =9.66, P < 0.05).

2) There are four types of marital status, including first married, divorced, unmarried, and remarried. Because the sample sizes in certain types are very small, they are merged into ‘with a spouse’ and ‘without a spouse’.
The sense of parenting competence and psychological distress in parents of latent classes
T-test was used to examine the difference between the two classes' sense of parenting competence and psychological distress (Table 3). The t-test showed that parents in the psycho-behavioural health group scored significantly higher on sense of parenting competence, satisfaction, and efficacy than those in the psycho-behavioural problem group(P < 0.05). However, parents in the psycho-behavioural health group scored significantly lower than those in the psycho-behavioural problem group on measures of parental psychological distress(P < 0.05).

Factors influencing the latent classes of psycho-behavioural adaptation among children
The values of variables entered in the binary logistic regression analysis. Were detailed in Table 1 in Appendix 1 of the supplementary materials. Results indicated that sense of parenting competence and parental psychological distress impacted latent classes of psychological behaviour adaptation among children. See Table 4 for details.
