The present study aimed to examine the prediction of school avoidance based on high school students' perceptions of family support and the quality of teacher-student relationships. The results indicated that psychological adjustment plays a significant role in predicting school avoidance. This finding is consistent with those of previous similar studies (
24,
36). Psychosocial adjustment is a multidimensional construct encompassing emotional, social, and educational dimensions (
35). Students with poor adjustment not only experience greater emotional difficulties but also struggle to communicate and cooperate with peers in school and classroom environments and lack sufficient motivation to learn (
13,
37,
38). Therefore, poor psychological adjustment exacerbates the tendency toward school avoidance.
Adequate psychological adjustment is also usually accompanied by a sense of self-efficacy, which enables individuals to act effectively when facing academic and life challenges and to resolve these challenges (
39). This factor may reduce the likelihood of school avoidance-related behaviors. Conversely, poor academic achievement and school avoidance are often associated with various psychological problems, such as morning anxiety (
4,
40), fear of separation from parents (
41), perceiving the school environment as threatening, low motivation for learning, and poor communication with peers (
42). These issues are more common among individuals with poor psychological adjustment.
Another finding of this study showed that perceptions of family support, through the mediating role of psychological adjustment, significantly predicted school avoidance among high school students. This finding is consistent with studies demonstrating a significant role of family functioning and family support in predicting school avoidance or dropout (
15,
43). Poor and unsupportive family functioning is generally associated with various psychological problems (
44), and this co-occurrence significantly reduces the likelihood of academic adjustment and academic achievement (
45,
46).
Chaotic and unsupportive families appear to influence adolescent adjustment and, consequently, problematic academic behaviors in two main ways. First, the family, as a source of stress, negatively affects the adolescent's emotional life, thereby increasing the likelihood of emotional difficulties. Second, such families influence the adolescent's motivation and desire for socialization, which in turn affects social life, an important dimension of psychological adjustment. Weakening these two dimensions of adjustment increases the likelihood of school-related problem behaviors (
15). In addition, families with a positive and supportive psychological atmosphere usually have children with more secure and adaptive attachment styles (
47). This secure attachment style is associated with more adaptive social relationships with peers and teachers in the school environment and, consequently, reduces the likelihood of maladaptive behaviors such as bullying or school avoidance (
48,
49).
Another finding of this study indicated that the quality of the teacher-student relationship, through the mediating role of psychological adjustment, plays a significant role in predicting school avoidance. This finding is consistent with previous studies (
26,
50). Classrooms are not only environments for learning but also appropriate settings for developing interpersonal relationships. In this context, teachers and the quality of their relationships with students play a fundamental role and have a significant impact on many aspects of students' academic and personal lives. Students who experience positive and constructive relationships with their teachers typically show greater interest in school activities and higher motivation to learn (
27,
51).
Furthermore, optimal teacher-student communication, particularly in terms of emotional support, is associated with the development of adaptive social and communication skills and psychological well-being among students, which are important constructs contributing to psychological adjustment (
52). Improved social relationships and psychological well-being, in turn, are associated with greater interest in learning and greater involvement in school activities. When the teacher acts as a "secure base" for students by being accessible, responsive, and receptive to their needs in a timely manner (
53), students tend to feel more competent (
54), show greater interest in learning, establish better relationships with peers, and experience better mental health. All these factors are associated with improved school behaviors (
53).
Given the significant predictive roles of family support and the teacher-student relationship, as well as their significant associations with the criterion variable, school avoidance, these two constructs appear to represent independent yet influential sources affecting school avoidance. The bases and sources of school avoidance can be divided into two distinct factors: factors outside school, the most important of which is the family (
44), and factors inside school, namely the quality of the relationship with the teacher (
52). Therefore, it is logical that these two factors, despite being distinct, are related to school avoidance. A student may experience an unpleasant family relationship and may not receive the necessary emotional support from the family. However, a positive relationship with the teacher, as an important figure in the student's communication network, and appropriate social support from school may serve as social reinforcement and reduce school avoidance behavior. In this regard, the school environment and the teacher-student relationship can function as reliable sources of emotional and psychological support for the student.
6.1. Conclusion
In light of these findings, family support and effective teacher-student communication play important and beneficial roles in psychological adjustment and in improving students' behaviors in the school environment. Therefore, psychological interventions addressing academic problems and school avoidance behaviors can focus on two main bases: families, through psychotherapists, and teachers, through school counselors. These factors are important for addressing students' psychological challenges. The family, as individuals' first social base, can pave the way for students' academic progress. Therefore, efforts to improve the family's relationship with students may facilitate students' interest in education.
6.2. Limitations
Despite these findings, the present study has limitations that should be considered when generalizing the results. First, the sample was selected conveniently; therefore, because of the non-random sampling method, it may not be representative of the adolescent population in other cities and provinces of the country. Second, this study was conducted cross-sectionally, and the sample included high school students from the general population. Therefore, future longitudinal studies are recommended, focusing on other populations, such as exceptional students, other provinces and cultures, and other age groups.
