3. Methods
Before interacting with any participants, we submitted our study protocol, survey materials, and interview questions to both the Shiraz University Research Ethics Review Committee and to the school administrators for each of the high schools from which we recruited participants. Each review committee granted us permission to conduct the study with their students as participants. In addition, we ensured that all participants knew that their participation was voluntary and that they would not incur any negative repercussions for choosing not to participate.
3.1. Population, Participants and Sampling
The respondents in Study 1 were 241 primary and secondary school students (137 Male and 104 Female) from two districts of the Department of Education in Shiraz city. The samples were selected through a multi-stage random cluster sampling method from the four districts of the Department of Education. To this end, two districts (districts 2 and 4) were initially selected from among the four districts and subsequently two schools, a girls’ school and a boys’ school, were selected. Next, a class from each secondary school grade was randomly selected in each school and the participating students within each of these selected classes were entered into the study as participants. In addition, the mean age of the participants was 16.52 and its standard deviation was 1.45. The participants were at least 14 and at most 20 years old.
3.2. Instruments
Creating the AcHS
In the present study we used an exploratory-sequential mixed-method to construct the current scale. To do this, we conducted semi-structured in-depth interviews with 20 students. We asked them questions about academic hope, such as “what is hope and what do you hope to achieve by studying?” We analyzed the students’ answers using the conventional qualitative content analysis method, and the key concepts were extracted. Next, 40 items were extracted based on theoretical foundations of Snyder’s theory (2) and Pekrun’s control-value theory of achievement emotion (6) as well as the key concepts extracted from the interviews with the students. In the next stage, we analyzed the content and face validity of the items on the questionnaire by asking experts among the psychology department faculty at Shiraz University to evaluate the appropriateness of each item. In the end, 27 out of the 40 items were selected and verified among these experts, and the rest of the items were discarded or merged into an existing item. Each of the 27 items on the scale were written as Likert scale questions, with responses ranging from 1 (completely disagree) to 5 (completely agree). The valence of items 6, 9, 10, 11, 13, 21, 24 and 27 were written in order to be scored inversely. After the questionnaire was administered, we analyzed the psychometric properties of the scale using exploratory factor analysis.
In addition to the academic hope scale used to assess the criterion validity, the following scales were also used with regard to the related literature: 1) children and adolescents patience scale (31) and 2) psychological hardiness scale (32).
4. Results
To investigate the validity of the AcHS, we conducted an exploratory factor analysis and calculated the Pearson’s correlations between the other scales like the patience scale and psychological hardiness scale with the subscales (hope to gain opportunities, hope to gain life skills, hope in school’s usefulness and hope to gain competency) and total test scores of AcHS. In addition, we calculated the Cronbach’s alpha on the reliability of responses across the AcHS.
4.1. Validity of Academic Hope Scale (AcHS)
Factor analysis to identify principal components. Before conducting our factor analyses, we examined whether or not the assumptions of factor analysis were met. That is, we examined whether the data met the assumptions of normally distributed data, lack of collinearity, and the elimination of outliers. The data appeared to meet all the necessary assumptions for us to proceed with performing a factor analysis (33). To determine the validity of the AcHS, we conducted a principal components analysis along with varimax rotation of factors. Our analyses indicated that the KMO coefficient (Kaiser-Meyer-Olkin measure of sampling adequacy of 0.926) and Bartlett’s test of sphericity (3536.29) reflected sufficient evidence for performing factor analysis. To determine the number of factors, we examined the Scree plot which indicated the existence of 4 factors as the components of the academic hope scale. The results of the factor analysis and factor loading of each item on each factor are presented in Table 1.

Based on the factor analysis, we identified four components of the academic hope scale. Each of these components was named based on the study items which loaded onto that factor. The first factor was named “hope to gain opportunities”. It indicated the existence of the hope and expectation an individual had for achieving occupational and social opportunities as well as success in their future life. Items such as “I can find an appropriate job in the future via schooling” assessed this component. Items 1, 2, 3, 4, 5, 8, and 14 assessed this factor.
The second factor was called “hope to gain life skills”. It referred to the hope and expectations students had that what they were learning at school would provide them with critical thinking skills and the skills for living in the community and interacting with others. Such items as “Whatever is taught to me at school will provide me with thinking skills.” expressed this factor. Items 7, 16, 17, 19, 20, 22, 23 and 25 assessed this component.
The third factor was called “hope in school’s usefulness”. Items such as “working in the market and being self-employed teach us more skills than spending time in school”, assessed the component of “hope in school’s usefulness”, which encompassed the hope and expectation that schooling and education were useful in having a good life and finding an appropriate job. Items 6, 9, 10, 11, 13, 21, 24 and 27 investigated this component.
Finally, the fourth factor was called “hope to gain competency”. Items such as “schooling will be followed by prestige and popularity for educated individuals” is an indicators of this component. Hope to gain competency reflected the hope and expectations based on which an individual anticipated they would obtain social reputation, popularity and prestige due to their education level. The component was assessed by items 12, 15, 18 and 26.
The results of the factor analysis indicated that the first factor (hope to gain opportunities), with an eigenvalue of 4.97, accounted for 18.43% of the total variance. The second factor (hope to acquire life skills), with an eigenvalue of 4.38, explained 16.23% of the total variance. The third (hope in school’s usefulness) and the fourth (hope to gain competency factors with eigenvalues of 3.62 and 2.57 also accounted for 13.44% and 9.52% of the total variance of the scale, respectively. The four subscales of the academic hope scale explained a total of 57.63% of the whole sample volume’s variance.
Calculation of the correlation between subscales and total test score
Another method used to evaluate construct validity is the calculation of the correlation between the subscales and the total test score (34). Furthermore, to assess the convergent validity of the academic hope scale with regard to the research background, its correlation with such scales as patience and hardiness was examined, the results of which are shown in table (2).

*P < 0.05 and **P < 0.01 |
The results of the correlation matrix showed that there was a positive relationship between psychological hardiness and hope to gain opportunities, hope in school’s usefulness, hope to gain competency, total hope score, acceptance, persistence, hesitation and total score of patience at the significance level of p < 0.01. Also, there is a positive relationship with sublimation and forbearance (two subscales of psychological hardiness) at p < 0.05. On the other hand, all the patience subscales and the four academic hope subscales had a positive correlation with the total scores of patience and academic hope at p < 0.01. The results also indicated the construct validity and convergent validity of the AcHS. That is, the results of the correlation matrix showed that the total hope score had positive and significant relationships with all its subscales (p < 0.01). Furthermore, the correlation between academic hope subscales was lower than the correlation between each of the subscales with the total hope score. This confirmed the discriminant validity of the subscales with one another and the convergent validity of the subscales with the total score of hope. We found a positive and significant correlation between respondents’ scores on the academic hope scale with their scores on the children and adolescents patience scale (31) and with the psychological hardiness scale (32). In fact, the results of the internal consistency provided evidence of the convergent validity of the AcHS with measures of patience and psychological hardiness.
4.2. Reliability of Academic Hope Scale
To assess the reliability of the academic hope scale, the internal consistency of the items and the Cronbach’s alpha coefficient were used, the results of which are presented in table (3).
Table 3
Cronbach’s alpha coefficients for the indicators of academic hope scale
Factors | Number of items | Cronbach’s alpha coefficient |
---|
Hope to gain opportunity | 7 | 0.90 |
Hope to gain life skills | 8 | 0.90 |
Hope in school’s usefulness | 8 | 0.80 |
Hope to gain competency | 4 | 0.76 |
Total score of academic hope scale | 27 | 0.94 |
As observed in Table 3, the Cronbach’s alpha coefficients for the subscales of hope to gain opportunities, hope to gain life skills, hope in school’s usefulness and hope to gain competency were 0.90, 0.90, 0.80, and 0.76, respectively. The total Cronbach’s alpha coefficient was also 0.94 for the AcHS, suggesting that the scale had favorable reliability.
