The present study aimed to examine the effectiveness of training on adaptive interpersonal skills learning among female teenager students. Training can ameliorate the assertiveness and sociability, caring and supportiveness, involvement scores, decreased aggression, and dependency traits among female high school students. The first finding suggests that social skills training can enhance adaptive interpersonal skill learning. This finding is consistent with the results of the studies by Albertyn et al. (
14), Bieber-Schut (
15), and Fallahchai (
16). Communication skill training can help students better identify their emotions and feelings with others, so they can receive greater social and emotional support from their environment (
17).
In the pre-test, we found that interpersonal skills were higher in the interventional group than the control group. The students in the interventional group could evaluate their mental beliefs and perceptions during training, so being aware of these trainings can contribute to successful adaptation to their own inner and outer world (
18).
Adaptability reflects a person’s willingness to interact constructively with others, especially friends and peers. Life skills training, especially interpersonal skills, helps students to understand a variety of psychological traits in themselves and others and accept them more transparently (
5).
This process makes it clear that intimacy and companionship should be developed in spite of some of the key differences between them and others (
4). Thus, various training programs should be facilitated to strengthen the adjustment level among students (
19).
In this study, the analysis of IIP32 components suggested a significant difference between interventional and control groups in terms of “caring” and “adaptive interpersonal communication” before and after the intervention, which was in line with the results of other studies (
6,
20,
21). This finding suggested that social skills training contributed to the high level of social adjustment among students and ultimately positively affected their academic performance (
13).
One of the significant goals of education is to help students achieve adaptability and build a useful and effective relationship with others as well as accept their social responsibility. Thus, it was necessary to pay attention to the development of social skills training among students (
22). Behpaxho et al. (
6) reported that social skills training would help promote the children’s adaptation in different aspects of life and was regarded as the most basic preventive program. Social skills training helped students reflect on their personal characteristics and be able to identify their weaknesses, make an attempt to modify them, and rely on these positive aspects, and improve their thoughts and emotions towards others.
On the other hand, considering the mean score of openness, no difference among students before and after training was seen, and openness did not improve in female high school students (
23). Students with higher openness were more intelligent and had better academic performance than other students. Life skills training can enhance academic performance and intelligence (
24). Students who had a higher degree of openness in interpersonal relationships benefited from their active imagination power to improve their academic performance (
25).
Also, we found that training assertiveness and sociability, aggression, supportiveness, and dependency traits were improved in female teenager’s students after intervention. This finding is consistent with the results of other studies (
24,
26-
29). Those skills helped the students experience more successful personal and interpersonal relationships because they have a reciprocal enhance the acceptance and a more friendly relationship, increase self-confidence, and ultimately maximize individual’ adaptability (
30).
Social skill training is a technique through which people learn how to expand an appropriate and enjoyable relationship in a variety of situations (
25). Most scholars agree that social skills can be learned because children raised in unsuitable environments have socially unconscionable behaviors and cannot speak effectively (
31). The development of social skills is a part of the socialization process in individuals, and the training should be exclusively offered on the basis of this process (
32). Training of emotional, social skills bring several benefits for individuals, including regulated emotions, stress control, emotional management, self-control, and interaction and subsequently lead to a decrease in non-social and aggressive behaviors and an improvement in interactions and desirable behaviors due to the person-environment interactions (
33).
In summary, the results of this study indicated that life skill training could affect the interpersonal skills of teenager students. Thus, those students who received a life skill training had more effective and better performance in their interpersonal relationships. For example, those who find themselves incompetent, unattractive, and boring in interpersonal relationships may tend to avoid communication with others. However, those who think of themselves as attractive, amiable, and valuable show more interest to communicate with others and build a friendly relationship. Also, students with poor interpersonal skills are less likely to be accepted by their peers.
5.1. Limitations
The limitations of this study are the small sample size and the existence of control variables. Also, factors such as economic status, single parenthood, parental education, and child rearing were undesirable variables that have undoubtedly influenced the results. Finally, the length of the measurement which causes fatigue could affect the results.
