The findings of the current study showed that emotion regulation, schema, and vandalism were respectively predictors of oppositional defiant disorder. The current study findings were similar to those of Garnefski et al. (
26), Eisenberg et al. (
27), Supple et al. (
28), Spencer et al. (
29), and Gadow et al. (
30), considering the relation¬ship between emotion regulation and oppositional defiant disorder. In fact, emotional reactivity and inadequate affective growth, as well as difficulties in emotional and behavioral regulation, would resulted in overcoming reasoning power by emotions, thus in different situations individuals make decision on the basis of environmental and emotional atmosphere regardless of various possible solutions (
31). Accordingly, these people often use disruptive disorders such as oppositional defiant behavior to deal with their negative emotions (
32,
33). The results of the current study in the case of schema and oppositional defiant disorder were consistent with those of Roelofs et al. (
34), Van Vlierberghe et al. (
35), Calvete (
36), Lochman et al. (
37), and Lochman and Dodge (
38). The findings indicated a pattern of defected childhood schema in disruptive disorder, specifically oppositional defiant disorder. To explain this assumption, maladaptive schemas lead to bias in the interpretation of events. This bias is created as misunderstandings, deviated approaches, inaccurate assumptions, purposes, and unrealistic expectations in individuals in mental pathology and these misinterpretations affect the future perceptions and evaluations since schemas are consistent during a person’s life and affect how that person connects to himself/herself and others. Schemas, by providing some prototypes for the methods of interpreting social cues and managing the social conflicts enable individuals to act effectively in their social world. Inefficient schemas can lead to the continuation of emotional and behavioral problems by a negative impact on the stages of accepting social information. Also, schemas can have an important role in the final stages of processing information that are the stages where the child predicts the consequences of various solutions of the issue and decides to choose the strategy, which shall be executed. In another explanation of this assumption, it can be said that encoding social cues, schemas can limit the attention of teenagers to special aspects of the social environment (
38). The current study findings regarding the relationship between oppositional defiant disorder and vandalism were similar to those of Kelley et al. (
39), Reynolds et al. (
40), and Mandel (
17). While expressing this finding, it can be concluded that individuals with a tendency toward destructive behaviors show the rate of their domination with dominance on objects and damaging them. In fact, aggression, as the basic sign of behavioral disorders, is caused by placing rage on external objects. Another factor, which can be referred in order to express this finding, is that individuals with a tendency toward destructive behaviors want to create variety and avoid uniformity with curiosity and manipulation of objects. These individuals avoid repetitive experiences, normal things, and predicted persons. Many of them try to improve their low level of arousal to the optimal level by participating in new activities. It seems that students seek new and unusual experiences and unexpected things, while encountering individuals and objects and might want to experience new things by manipulating the equipment and facilities of school (
41). On the other hand, individuals with erogenous oppositional defiant disorder cannot control their emotions and show their excitements by damaging the objects of school. Probably their lower levels of arousal cause them not to be afraid. Such individuals, in order to reach an optimal level of arousal, seek stimulations that are new and dangerous for normal people and create an undesirable anxiety.
Several limitations to the current study are noteworthy. First, since the current study was correlational, it did not represent the casual relationships between variables. Consequently, compared with experimental and semi-experimental studies, such studies have fewer authentications. Another limitation was restricting the sample to high school students due to methodology. It is suggested to perform similar researches on larger samples of oppositional defiant patients in other age groups to determine the quality of the relationship and present more reliable and generalized information. In addition, other gender, social, and economic variables may be also taken into account to expand the findings. Therefore, further studies investigating such factors can obviously lead to clearer results.
