Anxiety Levels

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 importance of developing and assessing student critical thinking at university can be seen through its inclusion as a graduate attribute for universities and from research highlighting the value employers, educators and students place on demonstrating critical thinking skills. Critical thinking skills are seldom explicitly assessed at universities. Commercial critical thinking assessments, which are often generic in context, are available. However, literature suggests that assessments that use a context relevant to the students more accurately reflect their critical thinking skills. This paper describes the development and evaluation of a chemistry critical thinking test (the Danczak–Overton–Thompson Chemistry Critical Thinking Test or DOT test), set in a chemistry context, and designed to be administered to undergraduate chemistry students at any level of study. Development and evaluation occurred over three versions of the DOT test through a variety of quantitative and qualitative reliability and validity testing phases. The studies suggest that the final version of the DOT test has good internal reliability, strong test–retest reliability, moderate convergent validity relative to a commercially available test and is independent of previous academic achievement and university of study. Criterion validity testing revealed that third year students performed statistically significantly better on the DOT test relative to first year students, and postgraduates and academics performed statistically significantly better than third year students. The statistical and qualitative analysis indicates that the DOT test is a suitable instrument for the chemistry education community to use to measure the development of undergraduate chemistry students’ critical thinking skills.

Background: The present study investigates the reliability and validity of the Positive–Negative Relationship Quality (PN-RQ) scale in Turkey. This study aims to test different factorial models including orthogonal factors model, correlated factors model, one-factor model, and bifactor model. Methods: In order to determine the validity and reliability of the scale, two studies were performed. The first was carried out with emerging adults (university students) who were in a romantic relationship (148 females, 43 males, and 2 unknown) and had the main purpose to examine the structure validity of the measurement tool in the Turkish sample with an exploratory analysis. Study 2 was performed online with 513 married adults (359 females, 149 males, and 5 unknown); confirmatory findings and criterion validity studies were added. Results: Exploratory factor analyses revealed that relationship quality had a two-factor structure and that there was also a negative relationship between the factors. Confirmatory factor analyses on the married sample showed that the bi-factor model provided evidence for the multidimensional nature of the scale. Both studies demonstrated high internal consistency. Conclusion: There is evidence for reliability and validity in the Turkish version of the PN-RQ scale to measure both positive and negative aspects of the relationship. The PN-RQ scale will be highly functional for social and clinical psychologists who work on close relationship issues in Turkey.

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.

Machiavvellianism is a personality trait which includes insincerity, callaousness and dishonesty. Although it was mainly studied by the literature of Psychopathology for a long time, Machiavvellianism is accepted as a trait which ordinary people has or must have, especially in competetive and extremely individualistic systems. Therefore this concept must also be studied in normal populations. Accordingly, the main aim of this research was to test the reliability and validity of Kiddie Mach (Christie, & Geis, 1970) in a Turkish speaking adolescent sample. A total of 471 adolescents (242 female, 225 male, 4 missing) were recruited for the study. The age range of the sample was 15-17 (Mean= 16.7, SD=.61). Exploratory and Confirmatory Factor Analyses indicated that scale had two dimensions. Two different analyzes were conducted to test the construct validity. First the extreme scores were compared for each subscale with t-test. The results showed that the mean differences between the upper and lower groups were significant. Second, Pearson Correlational Coefficients were analyzed between the Machiavvellianism total score which was formed as a sum of two subdimentions and narcissism, traditional ve cyberbullying, callaousness ve prosocial behaviors. All correlations were significant in expected directions. Allover results indicated that Machiavvellianism Scale was a reliable and valid measurement tool among Turkish speaking adolescents.

The aim of this research is to bring the concept of Self-Expectation for Organizational Improvement” (SEOI) to the field of organizational psychology and to develop a measurement tool by forming the theoretical-empirical background of this concept. In the study, firstly, the theoretical framework related to the concept of SEOI was established and the concept of SEOI defined as follows; independent of the planned actions of the organization management, self-expectations that the individual has designed completely in his/her own mind and that there will be positive improvements and developments within himself/herself, with the individuals around him/her, and in the organization. Subsequently, a pool of items was created in accordance with the theoretical framework, a draft scale was obtained and a pilot study was conducted with 87 employees to determine the validity and reliability of this draft scale. In the analysis, a two-factor structure was obtained from the draft scale and it was found that this structure met the reliability and validity criteria. This factor structure was then tested on the main sample of 274 employees. All findings of the statistical analyses on the data obtained from the pilot study and the main sample showed that the developed scale had scientific validity and reliability and the scale was sufficient to be used in scientific researches.
