Anxiety Levels

The learning in the physics laboratory is related to several non-cognitive variables such as anxiety which has a significant role in teaching and learning process. Therefore, university students may have different thoughts and anxiety levels towards physics laboratory class. The aim of this research was to develop a measurement tool assessing the anxiety levels of university students in a physics laboratory class. In this research the Physics Laboratory Anxiety Scale (P-LAS) consisting of 18 items was developed, and its validity and reliability were analysed. The sample consisted of 557 university students (295 female and 262 male) who take physics and/or physics laboratory classes at three different Faculties of Education. Validity of the scale was first assessed by expert review. Exploratory factor analysis was performed to assess structural validity, and revealed a one-dimensional structure. The loading values of all 18 items varied between 0.58 and 0.80, and explained 52% of the total variance. Cronbach’s alpha coefficient of internal consistency was calculated as 0.94 and the split-half test correlation was 0.76. These results showed that P-LAS can be used as a valid and reliable instrument in physics education. Keywords: physics education, physics laboratory anxiety, scale validity and reliability, university students.

University students’ achievements in organic chemistry depend on cognitive variables. In addition, non-cognitive variables such as anxiety levels also have an impact on students’ organic chemistry achievements. The aim of this study was to develop a measurement tool assessing the anxiety levels of university students in organic chemistry lessons. In this study, the Organic Chemistry Anxiety Scale (O-CAS) consisting of 24 items was developed, its validity and reliability was analysed. All the items are positively worded to indicate increased anxiety. Factor analytic evidence from a sample (n=340) of university organic chemistry students indicated that the O-CAS measured three constructs. Additional analysis with a second sample (n=297) showed that scores on these anxiety constructs were internally consistent, with Cronbach’s alphas ranging from 0.87 to 0.92 and were 0.95 for the overall scale. Further, the result of analysis of the third sample (n=195) indicated that there was a statistically significant relationship between organic chemistry anxiety and organic chemistry achievement of students. According to these results, the O-CAS can be used as a valid and reliable instrument in chemistry education. Key words: anxiety, chemistry education, organic chemistry, reliability, and validity.

The Health Belief Model

This study aimed to create a measurement tool for the determination of university students’ health beliefs about testicular cancer (TC) and self-examination. This is a methodological and cross-sectional study. The study sample included 425 university students. Consents and approvals were obtained from the relevant institutions and the ethics committee prior to the research. The data were collected using an interview form that included questions about descriptive characteristics, family history of TC, and knowledge, beliefs, and practice of self-examination. The health belief model including 41 questions about self-examination and the interview form were administered to the students in their classrooms at a suitable time. Principal components analysis and varimax rotation were used for the examination of the structures of the factors. Accordingly, factor patterns, self-values, and the variance percentages they explained were evaluated. The average age of the participants is 22.2 ± 2.3 (min = 17; max = 40). Of them, 98.8% of the participants are single ( n = 420). Of them, 56.2% have heard about TC before, and 18.4% said they were informed about TC. Factor loading of the items in the first factor was 0.64 to 0.89, while it was 0.48 to 0.75 for the items in the second factor, 0.50 to 0.87 for the items in the third factor, 0.37 to 0.68 for the items in the fourth factor, 0.51 to 0.68 for the items in the fifth factor, and 0.65 to 0.79 for the items in the sixth factor. The health belief model scale may be used in TC screenings for males to measure susceptibility, seriousness, health motivation, barriers, benefits, and self-efficacy.

The aim of this study is to investigate Social Appearance Anxiety in university students according to gender, type of faculty, grade level, body weight and height. The present study was conducted on students of Sakarya University who were between the ages of 17 and 25. 247 of the participants were female and 256 were male. The social appearance anxiety scale filled in by 503 students was evaluated. T-test, one-way analysis of variance and LSD tests were used in statistical operations. In this study, the Social appearance anxiety scale score was found to be slightly lower in women than in men in the comparison made by gender. This difference did not show a statistically significant difference according to gender (p>0.05). The social appearance anxiety score differs statistically significantly according to the type of education and training faculties (p<0.001). Social appearance anxiety changes significantly according to education level (p<0.001). It was found that the students who were satisfied with their body weight and height had lower social appearance anxiety than the students who were not satisfied. Social appearance anxiety varies according to height and body weight category (p<0.001). In conclusion, social appearance anxiety was found to be similar according to gender in this study. It differed according to the field of study of the students. The social appearance anxiety levels of the students receiving sports education are the lowest. Anxiety levels of students who receive art education are higher than those who receive sports education. The social appearance anxiety of the students who did not receive sports and art education is the highest. In order to reduce social appearance anxiety, students should be supported in sports and art education and practice.

Selfitis Behavior Scale

This study aimed to adapt the Selfitis Behavior Scale (SBS) to measure university students' selfitis behavior in Turkey. Within the scope of the study, the SBS was translated from English to Turkish. Data were collected in the validity and reliability studies from four study groups, including 343 university students. According to the confirmatory factor analysis findings, the SBS had good fit indices. As is expected, the criterion-related validity study found moderate- and highlevel positive correlations between the SBS subscales and total scores and the Selfie Attitude Scale (SAS) subscales and total scores. The other criterion-related validity study demonstrated that individuals taking a higher number of selfies than the sum of the scale and subscales scored significantly higher than individuals taking a lower number of selfies. The internal consistency coefficient was calculated to be .92 for the SBS total score, .78 for the Environmental Enhancement Subscale (SBS-EE), .68 for the Social Competition Subscale (SBS-SC), .72 for the AttentionSeeking Subscale (SBS-AS), .84 for the Mood Modification Subscale (SBS-MM), .82 for the SelfConfidence Subscale (SBS-S), and .70 for the Subjective Conformity Subscale (SBS-SCon). The test-retest correlation values found by applying the measurement tool once in four weeks were .77 (SBS), .70 (SBS-EE), .60 (SBS-SC), .82 (SBS-AS), .80 (SBS-MM), .61 (SBS-S), and .61 (SBSSCon), respectively. The mentioned findings demonstrated that the SBS was a valid and reliable measurement tool capable of measuring the selfitis behavior of university students in Turkey.

Internet addiction (IA) is widespread, comorbid with other conditions, and commonly undetected, which may impede recovery. The Internet Addiction Test (IAT) is widely used to evaluate IA among healthy respondents, with less agreement on its dimensional structure. This study investigated the factor structure, invariance, predictive validity, criterion validity, and reliability of the IAT among Spanish women with eating disorders (EDs, N = 123), Chinese school children (N = 1072), and Malay/Chinese university students (N = 1119). In school children, four factors with eigen values > 1 explained 50.2% of the variance, with several items cross-loading on more than two factors and three items failing to load on any factor. Among 19 tested models, CFA revealed excellent fit of a unidimensional six-item IAT among ED women and university students (χ2(7) = 8.695, 35.038; p = 0.275, 0.001; CFI = 0.998, 981; TLI = 0.996, 0.960; RMSEA = 0.045, 0.060; SRMR = 0.0096, 0.0241). It was perfectly invariant across genders, academic grades, majors, internet use activities, nationalities (Malay vs. Chinese), and Malay/Chinese female university students vs. Spanish women with anorexia nervosa, albeit it was variant at the scalar level in tests involving other EDs, signifying increased tendency for IA in pathological overeating. The six-item IAT correlated with the effects of internet use on academic performance at a greater level than the original IAT (r = −0.106, p < 0.01 vs. r = −0.78, p < 0.05), indicating superior criterion validity. The six-item IAT is a robust and brief measure of IA in healthy and diseased individuals from different cultures.
