The demographic and social characteristics of the participants are shown in Demographic and social characteristics of student participants (Since more than 98% of the participants were Kurds and spoke Kurdish, ethnicity and language were excluded from the list of confounding variables for FNLIT in the analysis. Age of half of the parents was 44–35 years (control = 52% and intervention = 47.4%). Most participants were the first children in the family (control = 35.4% and intervention = 45.2%). The four-person families had the highest number in both groups (control = 46.8% and intervention = 43.4%). Moreover, the parental education level of most participants was at the elementary level, and based on the results obtained from the Kruskal Wallis test listed in Comparison of FNLIT scores based on the demographic and social characteristics in both groups before and after the intervention.PThe number of subjects studied in both control and intervention groups was equal and they were identical in terms of age, gender, and educational levels in order to eliminate the confounding effect. Based on the results, the birth rank of one has the highest frequency in both control (35.3%) and intervention (45.3%) groups. Family size of four in both control (46.7%) and intervention (43.3%) groups were more frequent than others. The parents' age of most of the participants in both the control and intervention groups was between 35 and 44 years. The parent's education of most of the participants in both the control and intervention groups was the elementary level.In both the control and intervention groups, the fathers of the study subject were mostly workers, and the mothers were housewives. In both the control and intervention groups, the breadwinner of the family were their father. Most of the participants in the study in both groups did not have support resources. In terms of housing ownership status, most of the study participants in both the control and intervention groups stated that they owned their housing.At baseline, the FNLIT scores were not significantly different between the control and intervention groups (58.6 in the intervention and 58.3 in the control groups) (After the intervention, the total FNLIT score was 57.8 in the control group compared to 95.5 in the intervention group (Mean and standard deviation scores of FNLIT subscales in both control and intervention groups.P
