In our study parents of abused adolescents and their school parents had a significant role as the main perpetrators in severe forms of psychological and physical domains respectively, but in sexual abuse strangers were the main culprits.
Many studies have shown that younger children, particularly those under 1 year, are more likely to be abused severely within the family (
22) and fathers were more likely fatal child abusers, whereas mothers are the most likely to be involved in less violent manners of physical abuse (
19). We didn’t have access to sufficient documents on abuse of adolescents by school parents; however, in our findings they had a significant role in severe physical abuse of the students. And in severe sexual abuse the role of strangers was noticeable. Reports about perpetrators of sexual abuse are various in different studies, they may occur intra or extra familiar (
21). Finkelhore et al. (2014) reported that sexual abuse in female adolescents occurred 3% - 5.5% by family perpetrators and 0.6% - 3% by strangers (
23).
Recently several evidences demonstrated that child abuse and neglect is associated with alterations in neuroendocrine and neurotransmitter systems, and pro-inflammatory cytokines. Specific changes in brain are associated with mood regulation (
24) and medical disorders (cardiovascular disease, diabetes, irritable bowel syndrome, asthma) (
25,
26).
Adults misbehaved in childhood showed more symptoms of depression, anxiety, and impairment of mental health, alcohol and substance abuse (
27,
28), impact on educational outcomes in school age children (
29) and even unwanted pregnancy after sexual abuse (
30).
In one study results indicated that sexually abused females showed deleterious bio psychosocial sequels such as earlier onset of puberty, cognitive deficits, depression, dissociative symptoms, mal adaptive sexual development, asymmetrical stress responses, more major illnesses and persistent posttraumatic stress disorder and so on (
31). Another study reported that child victims of sexual abuse showed higher PTSD (post-traumatic stress disorder) scores and disruption in coping strategies. The effects of avoidance strategies were stronger in continued than in isolated abuse, and in intra familial than in extra familial abuse (
20,
32). In this study we didn’t asses the above mentioned mental biopsychological sequels, but we found statistically significant relationship between sexual abuse and stress as a mental outcome in that special domain.
In present study it seemed that the outcome of child abuse directly depends on who is the perpetrator in different domains. For instance, in neglected students, severe and very severe depression and anxiety were seen in adolescents who were abused by their parents and in physical abused adolescents, the most frequent severe and very severe depression was seen in cases abused by parents, and sexual abuse by strangers due to the most severe stress in the students.
Based on the results of regression analysis, female gender and substance abuse by parents were considered as common predicting factors for all abuse domains. In some studies poverty, unemployment, minimal education and partner’s psychological abuse were repeatable characteristics in the lives of all types of child abusers (
33) and problem behaviors such as alcohol and/or drug abuse (
34), history of violence (
35), and mental health problems have also been demonstrated as related factors for different domains of abuse (
36).
We have a variety of reports on frequency of different types of abuse in girls in comparison with boys. In one study lifetime experience of 17-year-olds with sexual abuse and sexual assault in girls was more than boys (26.6% vs 5.1%) (
23) and in other studies boys and girls were equally likely to be the victims of fatal child abuse which occurred at home (
37). Substance abuse by parents has also been considered as a strong risk factor for all domains of abuse in some studies (
38,
39).
Evidence has shown that allocating more money to support and caring at-risk children who have been removed from their homes, assigning permanent home, promoting their wellbeing and placing in foster care can modify the adverse effects of child abuse and neglect and break the faulty cycle (
40).
5.1. Conclusions
In the present study parents of abused adolescents and their school parents had significant role as the main perpetrators in severe forms of psychological and physical domains, but in sexual abuse strangers were the main culprits. Analyzing the data showed that, female gender and substance abuse by parents were considered as common predicting factors for all abuse domains. These findings could be as an alarm for health professionals and decision makers for prevention and intervention programming aimed at reducing both child abuse and poor mental health outcomes in adolescents.
5.2. Strengths and Limitations
A limitation of this study might be that we had not frequency of all abuse domains by father and mother separately. Instead of that we used “first degree relatives” as a general term. In present study several types of child abuse and mental conditions were assessed. However, the data from that were cross sectional and retrospective in nature. Despite that the sexual domain of our questionnaire was an advantage, since most similar studies in Iran did not included this part. It is clear that assessment of sexual abuse based on self-report will not be complete because some offenses will be forgotten and some will not be disclosed because of shame and distrust (
41). Another limitation of the study was underestimating of the results, probably because the parents didn’t premise their children to answer the questions if they really abused them. Finally, in our study we didn’t have any analysis about economic abuse because of the low ratio of working students.
