Abstract

Background/Objective:

This study represents a contribution to the validity and reliability of the 15-item Teacher Emotional Support Scale in a sample of Italian high school students (N=501; 80.2% females; M=15.66; SD=1.52). Therefore, the present paper aimed to examine the factor structure and to investigate the reliability and validity of the scale. Students’ perception of teacher emotional support refers to the students’ perception of whether and to what extent the teacher shows caring and understanding behaviours, promotes students' growth and establishes personal relationships with them.

Materials and Methods:

Confirmatory factor analyses confirmed that the hypothesized three-factor solution had the best fit to the data, assessing three different but related dimensions: Positive climate, Teacher sensitivity, and Regard for adolescent perspective. Furthermore, the reliability and convergent and discriminant validity can be considered adequate.

Conclusion:

The Teacher Emotional Support Scale could be considered as a valid instrument to assess high school students’ perception of the emotional support received from their teachers. Practical implications have also been discussed.

Keywords: Emotional support, Teachers, High school, Students’ perceptions, Classroom climate, Teacher support.



1. INTRODUCTION

1.1. Classroom Climate and Teacher Emotional Support

In the education sector, there is increasing attention to classroom climate as an indicator of students’ well-being and teaching quality [1-4]. Although an extensive literature has focused on school climate [5-7], considering classroom climate also may serve an important purpose [8]. Whereas school climate refers to the whole facets of school life and environments, from academic to organizational ones, classroom climate strictly refers to the interaction and the atmosphere set both by teachers and students [4, 9, 10]. Thus, classroom climate is understood as the subjective students’ perception of every dynamics that take place daily in the classroom [11-13] and could be considered as the result of multiple aspects: teacher-students and students-peer relationships, educational climate as well as educational practices [9, 14-16]. Teachers’ emotional support is crucial for students’ adjustment and has a pivotal role in classroom climate [17-26]. High school students, indeed, spend most of the time at school, experience new and complex duties, such as exams and tests, utterly different from the ones they have learned to deal with during primary school [27]. Thus, during this period, adolescents are deeply susceptible to the emotional support they received from adults in the school context [28]. The emotional relationship students establish with their teacher, indeed, is strictly related to academic success [29], school and overall life satisfaction [30], and psychological well-being [31]. Teachers’ emotional support refers to the ability of a teacher to create positive relationships with their students, promoting their autonomy and competencies as well as their emotional and social functioning [15]. According to one framework from Pianta and Hamre [23], emotional support encompasses three specific dimensions: positive climate, teacher sensitivity, and regard for adolescent perspective. Positive climate refers to what extent the teacher creates and promotes positive interactions in the classroom [2, 4, 23]. Teacher sensitivity refers to whether he/she is responsive to the student’s emotional, academic, and individual needs [2, 4, 23]. Finally, regard for adolescent perspective refers to how teacher encourages students’ autonomy, peer interactions and their social needs [2, 4, 23].

Students in classrooms with emotionally supportive teachers are more engaged, motivated, and show better academic performance than their counterparts [2, 32-34]. Conversely, various studies have highlighted the direct link between low levels of teachers’ emotional support and adverse academic outcomes, such as anxiety [35-41].

1.2. Students’ Perception of Teacher Emotional Support

Students’ perception of teacher support refers to their perception of whether and to what extent the teacher shows caring and understanding behaviors, promotes students' growth, and establishes personal relationships with them [23, 33, 42]. Students’ everyday classroom experience and their perceptions are related to the effectiveness of learning and instructions (see [15, 43-47]). Previous studies have underlined that students who perceive their teachers as high in emotional support also show high general adjustment and several positive outcomes (i.e., high academic achievement, emotional well-being, engagement, prosocial behavior, and peer support) [33, 34, 48-53]. Additionally, there is an inverse relationship between students’ perception of teachers’ emotional support and negative academic conditions [41, 54-57]. For instance, Kim and colleagues [58] have shown that among different sources of support, such as teachers, parents, and peers, teacher's support has the strongest negative relationship to student burnout.

1.3. The Present Study

Given the importance of students’ perception of teacher emotional support in determining a positive classroom climate [23, 59, 60], previous studies have shown some limitations. The existing self-report questionnaires, although exploring in some way the high school students’ perception of teacher support, give just a little attention to the emotional components and do not provide an in-depth differentiation of the quality of emotional support (e.g., The Child and Adolescent Social Support Scale, CASSS) [61]. Some others, instead, exclusively address special education (e.g., School Climate Inventory, SCI) [62]. Moreover, although the Organisation for Economic Co-operation and Development (OECD) [63] results suggest that Italian students are below the OECD average for students’ perception of teacher support, the few Italian instruments that have been published refer to school climate with little or no attention to teacher emotional support (e.g., Questionnaire on Perception of School Climate, SCPQ) [64]. As such, providing a reliable and valid instrument for use on high school students could serve as an important step in understanding student experiences, having a deeper perspective on the quality of teacher emotional support, as well as better designing professional development for teachers [25, 65-68]. This study represents a contribution to the validity and reliability of the Italian version of the Teacher Emotional Support Scale, used in Schenke and colleagues [4], and developed by Ryan and Patrick [42]. Although the original scale was designed for students in math classes, we decided to validate the instrument, referring to all the teaching staff. This choice was based on three main theoretical assumptions. First, Italian high school students, as opposed to the American ones where the original scale was tested, do not move from their classrooms for the entire school year, but teachers who taught different subjects move in the classrooms in different hours during the school day. Second, considering the latest Program for International Student Assessment (PISA) results [69], Italian high school students, compared to the other countries involved in the study, present lower scores in all the subjects taken into account (Italian, Sciences, and Mathematics). Furthermore, 57% of Italian High school students (21% in the OECD average) have skipped a day of school in the two weeks before the PISA test, and this index is usually related to lack of support and poor classroom climate [69]. Third, previous studies have shown the efficacy of interventions based on the three facets, regardless of the subject taught [70]. Thus, especially in the Italian context, there is a need to provide a scale that measures students’ perception of teachers' emotional support, and that is not subordinated to a single subject taught. Therefore, the present paper aimed to examine the factor structure and to investigate the reliability and validity of the scale. Firstly, the factor structure of the Italian version of the Teacher Emotional Support Scale was tested by comparing the goodness-of-fit of some alternative models. Specifically, the hypothesized model composed of three correlated factors (i.e., positive climate, teacher sensitivity, and regard for adolescent perspective) would better describe teachers’ emotional support in the classroom than a one-factor model (general emotional support) or a two-factor model. Secondly, the reliability of each dimension was investigated through Cronbach's alpha coefficient. Thirdly, the convergent and discriminant validity of Teacher Emotional Support Scale was investigated by examining its associations with school engagement dimensions (such as vigor, dedication, and absorption), classmate support (i.e., given social support and perceived social support), academic anxiety, and school burnout symptoms (i.e., emotional exhaustion, cynicism, and sense of inadequacy).

2. MATERIALS AND METHODS

2.1. Participants

This study used a cross-sectional descriptive design with convenience sampling. Participants were 501 Italian high school students (80.2% females; M=15.66; SD=1.52). In detail, students came from 26 classes and attended two different high schools from Central and Southern Italy: 60.6% belong to human sciences high school (90% females) and 30.4% high school specializing in classics subjects (57.9% females). Concerning school enrollment and considering that Italian high school lasts five years, 17.8% of the students attend the first year, 32.5% the second year, 19.8% the third year, 12.5% the fourth year, and 17.4% the last year. The research protocol was approved by the school council, and a letter describing the aim of the study and the informed consent form was provided to the parents of the students. Only participants whose parents provided informed consent took part in the study. All the participants freely consented to answer the questionnaires.

2.2. Procedure

Considering that Italian students follow lessons in the same classroom during the whole school year, participants completed the questionnaires in their own classrooms, during school hours and in a single session, with a paper-pencil approach. A member of the research team was present in case of need and gave all the necessary information to complete the questionnaire before starting. To avoid as much as possible social desirability bias, we informed all students that the questionnaires were anonymous, collected data were only used for research purposes, and that any teachers were able to view the responses. Teachers were not present in classrooms during the collected data to guarantee spontaneous responses.

Moreover, there was no specific or at-risk condition the researcher was aware of before the administrations. Thus, the first contact between the researcher and the students occurred on the day of data collection.

The research method complied with the norms of the Code of Ethics of the Italian Psychology Association [71], and anonymity and confidentiality standards were assured for all participants.

2.3. Instruments

2.3.1. Teacher Emotional Support

Teacher emotional support was evaluated by the Emotional Support Scale used in Schenke and colleagues [4]. The translation of the questionnaire followed the step below: Two native Italian-speaking educational researchers translated the items. Their translation was reviewed by Italian-speaking experts in educational research. Back translation of the questionnaire was then performed by a professional bilingual translator who was not involved in the initial translation. Finally, a comparison of the back-translated version and the original version of the questionnaire was performed by both Italian- and English-speaking natives.

The questionnaire consists of 15 items on a 5-point Likert scale (1= “Not at all true”, 5= “Very true”), measuring students’ perception of the teacher's emotional support. It evaluates three dimensions: Positive Climate, Teacher Sensitivity, and Regard for Adolescent Perspective. Positive Climate refers to students’ perception of whether their teacher is creating a positive emotional connection with them. It consists of 5 items (e.g., “Our teacher wants students in this class to respect each other’s ideas”). Teacher Sensitivity refers to what extent teachers pay attention to students’ individual and academic needs; it consists of 6 items (e.g., “Our teacher cares about how we feel”). Finally, Regard for Adolescents Perspectives refers to how teachers consider the social needs of students and promote interactions with peers. It encompasses 4 items (e.g., “Our teacher encourages us to share ideas with one another in class”). In the original study [4], Cronbach’s alpha was 0.82 for Positive Climate, 0.85 for Teacher Sensitivity, and 0.80 for Regard for Adolescent Perspective.

2.3.2. Classmate Support

Classmate support was evaluated by the Italian Questionnaire for Given and Perceived Social Support within Peer Relationships at School [72]. This questionnaire consists of 9 items on a 5-points Likert scale (1= “Never”, 5= “Always”) evaluating two dimensions: Given Social Support and Perceived Social Support. Example of Given Social Support is: “How often do you try to help your classmates when they are in need?”; an example of Perceived Social Support is: “How often your classmates try to cheer you up when you are sad?”. In the current study, the Cronbach’s alphas were 0.80 for Given social support and 0.87 for Perceived social support.

2.3.3. School Engagement

School engagement was evaluated by the Italian validated version of the Utrecht Work Engagement Scale for Students (UWES-S17) [73]. UWES-S is based on 17 items on a 7- points Likert scale (0= “Never”, 6= “Always”), evaluating three dimensions: Vigor, Dedication, and Absorption. Examples of Vigor subscale is: “In my schoolwork, I feel that I am bursting with energy; an example of Dedication subscale is: “I find my schoolwork full of meaning and purpose”; an example of Absorption subscale is: “When I am studying, I forget everything else around me”. In the current study, the Cronbach’s alpha was 0.83 for Vigor, 0.93 for Dedication and 0.81 for Absorption.

2.3.4. School Burnout

School burnout was assessed via the Italian validated version of the School Burnout Inventory (SBI) [74]. SBI consists of 9 items on a 6-points Likert scale (1 = “I totally disagree”, 6 = “I totally agree”). It evaluates three dimensions (i.e., Emotional Exhaustion, Cynicism, and Sense of Inadequacy). Example of Emotional Exhaustion subscale is “I often sleep poorly because of all the problems related to the study ”; an example of Cynicism subscale is: “I feel like I’m losing interest in school”; an example of Sense of Inadequacy subscale is “I used to have higher expectations of my schoolwork than I do now”. In the current study, the Cronbach’s alpha was 0.77 for Emotional exhaustion, 0.79 for Cynicism and 0.60 for Sense of inadequacy.

2.3.5. Academic Anxiety

Academic anxiety was measured by the anxiety subscale of the Italian Questionnaire for Anxiety and Resilience (QAR) [75]. The Anxiety subscale consists of 7 items evaluating through a 5-point Likert scale (1 = “Never”, 5 = “Always”). An example of the anxiety subscale is: “Just thinking about exams or tests makes me anxious”. In the current study, Cronbach’s alpha was 0.86.

2.4. Data Analyses

First, we performed an item analysis to investigate the items’ psychometric properties. Item analysis allows observing the characteristics (mean, standard deviation, skewness and kurtosis) of each item and deleting nondiscriminant items, i.e., those items that show extreme means and nearly zero standard deviation and that had skewness and kurtosis higher than |2| [76].

Second, we performed Confirmatory Factor Analysis (CFA) using Mplus 6.54 [77] on the three-factor model (M1) to assess whether the factor structure of the Italian version of the Teacher Emotional Support Scale replicated the original theorized structure [4]. We compared M1 with alternative models, i.e., a mono-factorial structure (M2) or a two-factor structure, obtained by combining two of the three dimensions (M3, M4 and M5). All models were tested using the maximum likelihood estimation method. We used the following goodness-of-fit indexes to assess the model: the Root Mean Square Error of Approximation (RMSEA < .08), the Standardized Root Mean Square Residual (SRMR < .08), the Comparative Fit Index (CFI ≥ .95) and Tucker Lewis Index (TLI) [78]. However, CFI and TLI values between .90 and .95 should be considered acceptable [79]. We performed the models’ comparison by computing a χ2 difference test [80], which indicates whether a given model (M1) fits significantly better or worse than alternative models. Specifically, a significant χ2 difference suggests that the fit indexes of the alternative model are significantly worse than M1. Third, we tested the internal consistency reliability of the scale through Cronbach's alpha coefficient. For Cronbach's alpha interpretation, George and Mallery [81] provided the following rules: α > 0.9 = Excellent, α > 0.8 = Good, α > 0.7 = Acceptable, α > 0.6 = Questionable, α > 0.5 = Poor, and α < 0.5 = Unacceptable. Finally, to assess convergent and discriminant validity, we calculated correlations between dimensions of Teacher Emotional Support Scale and other measures, and Average Variance Extracted (AVE). AVE indicates the level of variance captured by a latent variable versus the level due to the measurement error of its indicator. Specifically, following the procedure developed by Fornell and Larcker [82], AVE is the mean of the sum of lambda squares. The AVE values are included between 0 and 1. The square root of the AVE is considered acceptable when higher than 0.50, i.e., more than 50% of the variance of the latent variable is due to its indicators [82]. Convergent and discriminant validity were supported if the square root of the AVE for each latent variable is higher than its correlation with other constructs.

3. RESULTS

3.1. Descriptive Statistics and Correlations

Table 1 shows the results of item analysis (descriptive statistics).

The results showed the means ranging from 2.48 and 4.10. The items with low means were i9 (“Our teachers take a personal interest in students”; Teacher Sensitivity dimension), i2 (“Our teachers treat everyone in this math class fairly”, Positive Climate dimension), i6 (“Our teachers care about how we feel”, Teacher Sensitivity dimension), i8 (“Our teachers consider students’ feelings”, Teacher Sensitivity dimension), i12 (“Our teachers encourage us to help other students with their works”, Regard for Adolescent Perspective dimension), while highest mean items were i1 (“Our teachers want students in this class to respect each other’s ideas, Positive Climate dimension), i5 (“Our teachers want all students to feel respected”, Positive Climate dimension), i3 (“Our teachers want the students in this class to work well together”, Positive Climate dimension). Therefore, no item had extreme means or a standard deviation close to zero.

Furthermore, skewness and kurtosis were below |2|. Therefore, no items were deleted.

In line with theoretical assumptions, the three-factor model (M1) reached the criteria for fit adequacy: CFI = 0.918, TLI = 0.901, RMSEA = 0.086, and SRMR = 0.063. Furthermore, the comparison among models showed that hypothesized three-factor model (M1) was significantly better than other alternative models (M2-M1: Δχ2 = 351.78, Δdf = 3, p = <.001; M3-M1: Δχ2 = 233.79, Δdf = 1, p = <.001; M4-M1: Δχ2 = 310.17, Δdf = 1, p = <.001; M5-M1: Δχ2 = 327.45, Δdf = 1, p = <.001).

As Fig. (1) shows, the standardized solution of the three-factor model showed that standardized estimates of factor loadings were high, ranging from 0.51 and 0.87, with significant t values and small standard errors. Furthermore, Positive Climate was positively and significantly related to Teacher Sensitivity (r = .66, p < .01) and to Regard for Adolescent Perspective (r = .67, p < .01), as well as Teacher Sensitivity was positively and significantly related to Regard for Adolescent Perspective (r = .81, p < .01).

3.3. Reliability and Convergent and Discriminant Validity

Reliability, assessing through Cronbach’s alphas, showed good internal consistency for each scale, i.e. Positive Climate (five items, α = .74), Teacher Sensitivity (six items, α = .90) and Regard for Adolescent Perspective (four items, α = .81).

Table 3 shows the results of convergent and discriminant validity.

With regards to convergent validity, results revealed significant positive correlations among Positive Climate, Teacher Sensitivity, and Regard for Adolescent Perspective and the three dimensions of School engagement (Vigor, Dedication, and Absorption). Furthermore, Positive Climate, Teacher Sensitivity, and Regard for Adolescent Perspective were positively and significatively related to Given Social Support and Perceived Social Support.

With regard to discriminant validity, the three dimensions of the Teacher Emotional Support Scale were moderately and negatively correlated to the three dimensions of SBI (Emotional Exhaustion, Cynicism, and Sense of Inadequacy). Moreover, while Academic Anxiety was moderately and negatively correlated with Teacher Sensitivity, there were no significant correlations to the other two dimensions of the Teacher Emotional Support Scale (p>0.05). Therefore, these results support the convergent and discriminant validity of the Teacher Emotional Support Scale. Finally, we calculated and reported in Table 3, the square root of the AVE for each dimension. The three square roots of the AVE was higher than .50, supporting good convergent validity. However, they were slightly lower than correlations to other constructs (Fig. 1). Therefore, the discriminant validity of the three dimensions was not fully supported. Indeed, although Positive Climate was sufficiently distinct from the other two factors, the measurements of Teacher Sensitivity and Regard for Adolescent Perspective may partially overlap. Therefore, we also requested modifications indices, in order to investigate as a three-factor model may improve. Results of modifications indices showed that only the item 14 (“My teachers listen to what I have to say”), measuring Regard for Adolescent Perspective, significantly improves fit indices if it was also loaded to Teacher Sensitivity. Therefore, the overlapping may be limited to this item.

4. DISCUSSION

The purpose of this study was both to validate the Teacher Emotional Support Scale from Schenke and colleagues [4] and developed by Ryan and Patrick [42] to the Italian academic context, and to evaluate its psychometric properties, investigating its dimensionality, reliability and convergent and discriminant validity. Our findings have suggested that Teacher Emotional Support Scale is a valid and reliable scale to measure students’ perception of teachers’ emotional support in the classroom. Our study represents the first Italian validation of a self-report questionnaire concerning students’ perception of teacher emotional support. Furthermore, and to the best of our knowledge, this instrument is the first to provide a clear and specific distinction of the different facets of teacher emotional support a student could perceive in his/her daily school life. Details about the results were discussed in the sections below.

4.1. Factorial Structure of the Model

We investigated the latent structure of the scale by comparing a series of alternative factorial models: the hypothesized three-factor model, a one-factor model (general emotional support), and a two-factor model (obtained by combining two of the three dimensions). The high correlation between two of the three dimensions of the scale (teacher sensitivity and regard for adolescent perspective) lead us to test the two-factor model. Despite the high correlation, results from the factor analysis suggest the separation of these two dimensions, showing that the three-factor-solution had the best fit for the data. Following the original study [4], positive climate, teacher sensitivity, and regard for the adolescent perspective better represent teacher emotional support and are closely related, but separate constructs. Previous studies, indeed, have shown that students who perceived a high positive climate also report lower dropouts rates and higher academic achievement [29, 83], and that perceived teacher sensitivity was related to higher vocabulary and decoding skills [84]. Moreover, other evidence suggests that students who perceived their teachers promoting autonomy in the classroom also reported higher levels of engagement [85]. These findings further support the three-dimensionality of perceived teacher emotional support and suggest that specific difficulties in the academic context could depend on gaps in specific areas of teacher emotional support. Besides, taking into account the distinction of the three dimensions could help to target specific training courses for teachers, focused on the single facets of the emotional support that should have to be improved in their respective classrooms.

4.2. Convergent and Discriminant Validity

In order to investigate the convergent and discriminant validity of the Teacher Emotional Support Scale, we examine its associations with School Engagement dimensions, Classmate Support, Academic Anxiety, and School Burnout symptoms. Our findings showed that both Engagement dimensions and Given and Perceived Social Support from Classmates were positively associated with Teacher Emotional Support dimensions: the higher teachers gave emotional support to their students, the higher students felt engaged, gave support to classmates, and received it back. In detail, and in line with previous findings [48, 53, 86, 87], students are more dedicated to the school context when teachers take care of their feelings and promote their social interaction and development. Furthermore, correlation results revealed differences in the magnitude of the coefficients across the dimensions of the Teacher Emotional Support Scale. For instance, considering UWES dimensions, Vigor and Absorption showed a weaker relationship with Positive Climate, when compared to the other dimensions of the scale. The same state could be observed considering the relationship among Given social support and each dimension of the scale. These findings suggest that Positive Climate, Teacher Sensitivity, and Regard for Adolescent Perspective are related but different constructs.

Moreover, while school burnout dimensions were negatively related to all the teacher's emotional support dimensions, academic anxiety was only (negatively) related to teacher sensitivity. This unexpected result could be better understood in light of the definition of the discriminant validity of Pedon [88], which asserts that discriminant validity is stronger when no relationships between the two measures considered are in place. Furthermore, the evidence that each dimension of the construct is related to the same outcome in different ways, as for academic anxiety, strongly supports the three-dimensionality of the Teacher Emotional Support Scale.

Furthermore, convergent validity was further supported by the results of the square root of the AVE, which suggested that more than 50% of the variance of the latent variable is due to its indicators rather than measurement error. However, the discriminant validity of three factors was not fully supported, specifically due to the high correlation between Teacher Sensitivity and Regard for Adolescent Perspective. The results of comparison among different factor models, however, clearly showed that the hypothesized three-factor model better fitted than other alternative models. Specifically, also the fit indices of the two-factor model (M5) - with a factor only composed of items of Positive Climate and the other factor composed of all items of Teacher Sensitivity and Regard for Adolescent Perspective - were significantly worse.

4.3. Limitations and Suggestions for Future Research

There are some limitations to this study that are important to note. First, due to the imbalanced sample, the generalization of results based on gender should be managed with caution. For future research, it would be interesting to replicate the present study with a gender-balanced sample. Moreover, participants are from Central and Southern Italy, and they are not representative of the whole Country. Finally, it could be interesting for further researches to include other Italian high schools’ educational programs in order to have a deeper frame of the studied variables in the Italian academic context. Finally, although our results suggested that the Italian version of the Teacher Emotional Support Scale is a reliable and valid instrument to measure three hypothesized dimensions, further studies are necessary to support discriminant validity.

CONCLUSION

In conclusion, the Teacher Emotional Support Scale could be useful to understand if students perceived their teachers as emotionally supportive, especially to what extent they are able to create a positive climate in the classroom, as well as respond to students’ emotional and social needs. This instrument, in addition to observational measures [2], could offer a more extensive understanding of classroom climate and teacher-student relationships, giving more attention to students’ points of view. The scale aims to be a valid instrument for teachers to figure out what they have to enhance with students to strengthen their relationship. Furthermore, in light of the showed link between teacher emotional support and significative facets of students’ daily life, further studies should be conducted to deepen these aspects. The insight into the dynamics of this relation (considering, for instance, the role of classmates support and engagement) could facilitate educators, practitioners, and psychologists to plan specific preventive measures in classrooms to ensure the onset of adverse school outcomes.
