1- INTRODUCTION

     Adolescence is the transitional phase between infancy and adulthood. It includes some big changes — to the body, and how it relates to the world as a young person. For both children and their families, the many physical, behavioral, cognitive, social, and emotional changes that occur during this period will bring excitement and anxiety (1). The adolescent seeks to shape the identity of the "I" in himself, the feeling tells man, who is he, and where he stands in the social system (2). Creation of identity is one of the fundamental conditions for the formation of an accepted society in all cultures, and Erickson (1968) believes that identity formation is a lifelong process that becomes increasingly important during adolescence and perceived as self-perception (3). Adolescents should engage in the development of educational and professional goals while shaping an image of who they are and want to be. Some studies indicate that a fairly straightforward and secure identity makes people more resilient, analytical and independent in making important life decisions, while at the same time promoting a sense of competence and self-efficacy (4).

According to Erickson's theory, identity is a frame that an individual uses it to perceive personal experiences and to guide his or her existence. Moreover, if the identity properly established, it may lead to a person's proper judgment, a feeling of inner unity, and a capacity for good action (5, 6). Berzonsky's social-cognitive theory claims that in their personal settings, people have three distinct types of identity (7). This theory suggests that people with information styles tend to describe themselves with personal characteristics (my values, my goals, and my criteria) (8).  Normal identity style is negatively related to openness and shows a positive relationship with the need to be closed. In fact, such individuals respond largely to decision-making situations by following the prescriptions and expectations of important individuals and are committed to institutionalized norms or conventions or are somehow committed to identity (9).

A person with active exploration or flexible commitment style demands a high level of self-confidence. People with normal identities and information styles in day-to-day situations manage benefit from a measured and logical mechanism (10), and the result of achieving this stable identity is to build commitment to values and goals (2). Berzonsky also considers commitment as a purposeful frame of reference in which behaviors and feedback are reviewed (7-9). This controlling framework evaluates and regulates behavior. Commitment clarifies the expectations, goals, principles, and ideals that people are involved in and want to maintain. People with this style feel purposeful and oriented (2). This controlling framework evaluates and regulates behavior. It plays an effective role in shaping their identity, which is not a simple process and has different dimensions (9).

Self-efficacy beliefs are the primary and fundamental basis of human motivation, linked to numerous cognitive and motivational factors such as control of emotions (11-12). It is assumed that self-efficacy derived from social cognitive theory undergirds goal taking and decision making, and governs the drive and commitment with which one pursues activities. Self-efficacy is affected by a person's previous performance experience with related activities, as well as by other social signals obtained (13).

Adolescence is a developmental phase characterized by marked changes in the underlying behavioral and psychobiological mechanisms, due to the maturation of the neuroanatomic circuitries, the complexity of the environments and the related developmental activities (autonomy, intimacy, etc.). Psychobiological organizations of adolescents are modulated by experiences between person and context dimensions resulting in various working habits, from positive to negative functioning (14). While the development of personality is defined by consistency, dimensions of temperament and character have different patterns of development (15). While most adolescent students may not have identifiable psychiatric problems, experts agree that puberty is a crucial period for psychological trauma. Given this wide variety of changes and transitions in this era, finding the right solutions is very important for teenagers. Deficiency in these areas has adverse effects including anomalies, anxiety feelings, temperament, interpersonal problems, and behavioral disorders (16).  When they have adequate growth and skills, they may have features such as trust, confidence, self-identification, self-efficacy, and self-esteem through the processing of cognitive, motivational, and emotional skills that could be the requisite knowledge and skills for a skillful behavior (5, 6).

As research studies on the effectiveness of reality therapy on identity styles (17) and increasing self-efficacy (18, 19) have shown, it can be considered as one of the effective approaches in strengthening self-efficacy and identity style. The aim of reality therapy is to teach a person how to make more meaningful decisions to handle their lives and improve their ability to cope with life's stresses and problems (19). The adolescent students are on the verge of identifying, making important decisions for the future, gaining cognitive, emotional, and social independence from their parents and others, and being exposed to the complex dangers of the world today (20). Thus, educating them in identity formation and personality development is an inseparable part of their lives, and the lack of attention to it causes irreparable damages to individuals and, consequently, to society (21).

A review of identity and self-efficacy styles research suggests that despite their influential role in the formation of adolescents' personality and their academic/career future, little research has been done on the impact of education and the reality treatment on the students' self-efficacy and identity styles. Such studies can be useful for teachers, administrators, and people involved in education. Based on this, the present study seeks to answer the question: Does teaching reality therapy have an effect on self-efficacy and identity styles of female students?

2- METHODS

2-1. Study design and population

The current study was a quasi-experimental study with pretest-posttest design, having both experimental and control groups. The present study's statistical population were all of the female students in all secondary schools in the second district of Tehran during the academic year 2018-19. For this reason, in this study two methods were applied. The first, one school was randomly selected from the secondary schools of region two using the random cluster sampling process, and out of that school's 458 students, 30 were randomly selected and substituted in the experimental (n=15) and Control (n=15) groups. Reality therapy preparation sessions for 10 days of 90-minute sessions were administered to the experimental group, and the control group received no intervention.

2-2- Inclusion and exclusion criteria

The following criteria were to be met for participation in the study: Completing the form of informed consent for participation in the research by the students’ parents, having a self-efficacy score one standard deviation below the average, having confused identity style and not receiving a plan of treatment and co-education during the training course, not suffering from physical or psychological illness. Exclusion criteria included more than two absences in training sessions, incompletion the conscious consent and questionnaires.

2-3. Performing Method

In the present study, one school was accidentally selected from among the three schools of district two in the south of Tehran; and after obtaining the consent of the school authorities and informing the students about the implementation of the research plan and considering the inclusion and exclusion criteria 30 out of 458 students in the school were purposefully selected from among the 458 students.  Afterwards, the participants were randomly assigned to the experimental (n=15) and control (n=15) groups. Then, the reality therapy group was trained in ten sessions for ninety minutes one day a week. The control group was not given any training. After all meeting sessions being implemented, the two groups were tested in the same conditions. In order to observe the ethical principles in the study for the control group, after the post-test implementation of the experimental group, the training sessions were considered for the control group.

2-4. Ethics

In this study all ethical guidelines from Helsinki were considered. It should be noted that informed approval has been received, and voluntary participation in the study is being observed.

2-5. Research tools

The Adolescent Self-Efficacy Scale:     This     scale was developed by Muris to assess adolescent self-efficacy. It has 24 items and three areas of academic, social, and emotional self-efficacy. Each dimension includes 8 items, items 1 to 8 for academic self-efficacy, items 9 to 16 for social self-efficacy, and items 17 to 24 for emotional self-efficacy. The answers in this questionnaire are calculated based on a range of five degrees (very bad to very good).  To determine the validity of the questionnaire in addition to the correlation of each dimension with the total score, Muris (22) used the factor analysis method with principal component analysis method and orthogonal rotation; and the correlation of each dimension with the total dimension was confirmed as follows: for the academic self-efficacy dimension, 0.30, for the social self-efficacy dimension, 0.10 and for the emotional self-efficacy dimension, 0.47.  Muris reported the reliability of this tool using Cronbach's alpha coefficient for the total scale, as well as the dimensios of academic, social, and emotional self-efficacy as 0.88, 0.85, 0.88, and 0.86, respectively.  In Dehghani-Zadeh and Hossein chari (23) research, the Cronbach's alpha reliability for self-efficacy dimensions was reported to be 0.70, 0.69, and 0.74, respectively.

Identity styles questionnaire: Identity Styles Questionnaire was developed by Brzonski et al. (24) to measure the cognitive-social processes that adolescents use in dealing with identity issues. This questionnaire has 40 items measuring four components of "information identity" with questions 37, 35, 33, 30, 26, 25, 18, 16, 6, 5, 2, "normative identity" with questions 40, 34, 32, 28, 23, 21, 19, 10, 4, "Confused or avoidant identity" with questions 38, 36, 31, 29, 27, 24, 17, 13, 8, 3, and "Identity commitment" with questions 7, 1, 9, 12, 11, 15, 14, 39, 22, 20. The commitment scale is used for secondary analysis and is not an identity style. Questions are scored on a five-point Likert scale (strongly disagree = 1, disagree = 2, somewhat agree = 3, agree = 4, strongly agree = 5) (24). Questions 9, 11, 14, and 20 are scored inversely so that they are completely disagree = 5, disagree = 4, somewhat agree = 3, agree = 2, strongly agree = 1. The minimum and maximum scores are 11 and 55 in the information style, 9 and 45 in the normative style, and 10 and 50 in the confusing-avoidance style, respectively. Reported test-retest reliabilities for the sub-scales range from 0.71 to 0.75; internal reliabilities showed alphas ranging from 0.68 to 0.73 (7). Berzonsky also reports acceptable validity data. In Iranian population, the Cronbach's alpha for assessing reliability was estimated in the range of 0.69 to 0.76 and the reliability using the test retest analysis ranged from 0.52 to 0.71(25).

2-6. Data Analyses

Descriptive statistics and inferential statistics (Multivariate Analysis of Covariance_  MANCOVA) were used to analyze the data. It should be noted that all data analysis was performed using SPSS software ve.23.0. Level of significant was p< 0.05.
