According to Self-Determination Theory (SDT), satisfaction of needs for autonomy, competence, and relatedness is a universal requirement for psychological well-being. We tested this hypothesis with college students in the United States, Australia, Mexico, Venezuela, the Philippines, Malaysia, China, and Japan. Participants rated the extent to which these needs, plus needs for self-actualization and pleasure-stimulation, were satisfied in various roles and reported their general hedonic (i.e., positive and negative affect) and eudaimonic (e.g., meaning in life, personal growth) well-being. Asian participants averaged lower than non-Asian participants in perceived satisfaction of autonomy, competence, and self-actualization needs and in most aspects of eudaimonic well-being, and these differences were partially accounted for by differences in dialecticism and independent self-construals. Nonetheless, perceived need satisfaction predicted overall well-being to a similar degree in all cultures and in most cultures provided incremental prediction beyond the Big Five traits. Perceived imbalance in the satisfaction of different needs also modestly predicted well-being, particularly negative affect. The study extended support for the universal importance of SDT need satisfaction to several new cultures.

Are more students cheating on assessment tasks in higher education? Despite ongoing media speculation concerning increased ‘copying and pasting’ and ghostwritten assignments produced by ‘paper mills’, few studies have charted historical trends in rates and types of plagiarism. Additionally, there has been little comment from researchers as to the best way to assess changes in plagiarism over time. In this paper, we discuss the relative strengths and weaknesses of research designs for assessing changes in plagiarism over time, namely cross-sectional, longitudinal, and time-lag. We also report the results of our own time-lag study of plagiarism. We assessed self-reported engagement in, awareness of, and attitudes towards plagiarism in three comparable groups of students at the same university on three occasions, each separated by five years (2004, 2009, and 2014). The data from our study paint an encouraging picture of increased understanding and reduced occurrence of several forms of plagiarism, with no upward trend in verbatim copying or ghostwriting. We suggest that technological and educational initiatives are counteracting the potential for increased plagiarism from online sources.

The highest estimates of the prevalence of commercial contract cheating in Australia come from self-report surveys, which suggest that around 2% of students engage in commercial contract cheating during their higher education studies. However, self-report surveys are limited in that participants under-report socially-undesirable behaviours. In this study, we used an incentivised truth-telling method and surveyed 4098 students from six universities and six independent higher education providers in Australia. We found that 2.46 times more students admitted to commercial contract cheating, via submitting ghost-written assessments, when truth-telling was incentivised (via a Bayesian Truth Serum methodology) rather than when normal self-report survey instructions were used. Using prevalence estimation formulae that are combined with the incentivised truth-telling method, we estimate that 7.9% of students buy and submit assignments from commercial contract cheating services. Additionally, 11.4% outsource assessments via obtaining pre-written work from commercial file-sharing sites. These are substantially higher percentages of commercial contract cheating than self-reports suggest. Furthermore, having a first language other than English was the strongest demographic predictor of Australian students’ engagement in commercial contract cheating. We conclude that commercial contract cheating is a more common problem than suggested by self-report surveys. We argue that academic integrity researchers should consider methods beyond standard self-reports to estimate the prevalence of academic misconduct and that efforts to curb commercial contract cheating must be increased.
