Sleep is an important component of healthy lifestyles. Worldwide reports suggest that one in every three adults suffers from insomnia. University students are vulnerable to insomnia due to their stressful lifestyle and inconsistent sleeping schedules, which contribute to poor, sleep hygiene. The purpose of this study is to explore the prevalence of sleeping problems among university students in Qatar and to investigate factors contributing to insomnia development. A cross-sectional survey utilizing two validated sleep questionnaires, the Pittsburgh sleep quality index (PSQI) and the sleep hygiene index (SHI), were administered to Qatar University (QU) students in either English or Arabic. An online survey was sent to all QU students through e-mail. Descriptive and inferential statistics were used to analyse and report the findings. A total of 2,062 students responded to this survey. Most of the respondents were females, Qataris, and the majority of them belonged to the colleges of Arts and Sciences, Business and Economics or Engineering. Around 25% of the participating students reported previous use of sleep aids. The findings indicated that the majority of the students had poor sleep quality (69.7%) and poor sleep hygiene (79%). A positive association was found between sleep quality and sleep hygiene (r = 0.39; p < 0.0001). College distribution and marital status were shown to significantly influence sleep quality (p =0.031 and p=0.02 respectively). The regression analysis revealed that sleep hygiene had the greatest effect on sleep quality (accounting for 7% of the variance) and individuals with good sleep hygiene were 4 times more likely to have good sleep quality. The findings of this study suggest that poor sleep quality and inadequate sleep hygiene practices are common among university students in Qatar, both of which may have a negative impact on students’ academic performance which warrants further investigation in future studies.

Abstract. Music video (MV) content is frequently measured using researcher descriptions. This study examines subjective or viewers’ notions of sex and violence. 168 university students watched 9 mainstream MVs. Incidence counts of sex and violence involve more mediating factors than ratings. High incidents are associated with older viewers, higher scores for Expressivity, lower scores for Instrumentality, and with video orders beginning with high sex and violence. Ratings of sex and violence are associated with older viewers and lower scores for Instrumentality. For sex MVs, inexperienced viewers reported higher incidents and ratings. Because MVs tend to be sexier but less violent than TV and film, viewers may also use comparative media standards to evaluate emotional content MVs.

The current study proposes and refines the Appraisals in Personality (AIP) model in a multilevel investigation of whether appraisal dimensions of emotion predict differences in state neuroticism and extraversion. University students (N = 151) completed a five-factor measure of trait personality, and retrospectively reported seven situations from the previous week, giving state personality and appraisal ratings for each situation. Results indicated that: (a) trait neuroticism and extraversion predicted average levels of state neuroticism and extraversion respectively, and (b) five of the examined appraisal dimensions predicted one, or both of the state neuroticism and extraversion personality domains. However, trait personality did not moderate the relationship between appraisals and state personality. It is concluded that appraisal dimensions of emotion may provide a useful taxonomy for quantifying and comparing situations, and predicting state personality.

Abstract. The need for efficient personality inventories has led to the wide use of short instruments. The corresponding items often contain multiple, potentially conflicting descriptors within one item. In Study 1 ( N = 198 university students), the reliability and validity of the TIPI (Ten-Item Personality Inventory) was compared with the reliability and validity of a modified TIPI based on items that rephrased each two-descriptor item into two single-descriptor items. In Study 2 ( N = 268 university students), we administered the BFI-10 (Big Five Inventory short version) and a similarly modified version of the BFI-10 without two-descriptor items. In both studies, reliability and construct validity values occasionally improved for separated multi-descriptor items. The inventories with multi-descriptor items showed shortcomings in some factors of the TIPI and the BFI-10. However, the other scales worked comparably well in the original and modified inventories. The limitations of short personality inventories with multi-descriptor items are discussed.

Although patients of cosmetic surgery are increasingly ethnically diverse, previous studies have not examined ethnic differences in attitudinal dispositions toward cosmetic surgery. In the present study, 751 British female university students from three ethnic groups (Caucasians, South Asians, and African Caribbeans) completed measures of acceptance of cosmetic surgery, body appreciation, self-esteem, and demographic variables. Initial between-group analyses showed that Caucasians had lower body appreciation and self-esteem than Asian and African Caribbean participants. Importantly, Caucasians had higher acceptance of cosmetic surgery than their ethnic minority counterparts, even after controlling for body appreciation, self-esteem, age, and body mass index. Further analyses showed that ethnicity accounted for a small proportion of the variance in acceptance of cosmetic surgery, with body appreciation and self-esteem emerging as stronger predictors. Possible reasons for ethnic differences in acceptance of cosmetic surgery are discussed in Conclusion.

Abstract. In the current study, we examined the viability of a multidimensional conception of perceived person-environment (P-E) fit in higher education. We introduce an optimized 12-item measure that distinguishes between four content dimensions of perceived P-E fit: interest-contents (I-C) fit, needs-supplies (N-S) fit, demands-abilities (D-A) fit, and values-culture (V-C) fit. The central aim of our study was to examine whether the relationships between different P-E fit dimensions and educational outcomes can be accounted for by a higher-order factor that captures the shared features of the four fit dimensions. Relying on a large sample of university students in Germany, we found that students distinguish between the proposed fit dimensions. The respective first-order factors shared a substantial proportion of variance and conformed to a higher-order factor model. Using a newly developed factor extension procedure, we found that the relationships between the first-order factors and most outcomes were not fully accounted for by the higher-order factor. Rather, with the exception of V-C fit, all specific P-E fit factors that represent the first-order factors’ unique variance showed reliable and theoretically plausible relationships with different outcomes. These findings support the viability of a multidimensional conceptualization of P-E fit and the validity of our adapted instrument.

Abstract. Previous research suggests that parenting style influences the development of the needs for achievement, power, and affiliation. The present study investigated the relationship between parenting style and another important motive disposition – the need for autonomy – in a sample of Singapore university students ( N = 97, 69% female), using a cross-sectional and retrospective design. It was predicted that an authoritative perceived parenting style would relate positively to the implicit need for autonomy ( nAut), the explicit need for autonomy ( sanAut), and the congruence between these two motive dispositions. Authoritative maternal parenting was found to positively associate with sanAut, while maternal parenting was not found to associate with nAut, or with nAut/ sanAut congruence. Paternal parenting was not associated with any of the dependent variables.

Abstract. The Dark Triad is a constellation of three antisocial personality traits: Machiavellianism, narcissism, and psychopathy. Recently, researchers have introduced a “Dark Tetrad” that includes subclinical sadism, although others suggest considerable overlap between psychopathy and sadism. To clarify the position of sadism within the Dark Triad, an online study was conducted with 615 university students. Exploratory factor analysis revealed that a six-factor solution fit the data best, representing Machiavellianism, psychopathy, physical sadism, verbal sadism, narcissism, and vicarious sadism. Furthermore, convergent validity was supported through sadism’s correlations with the HEXACO personality traits. The results support sadism’s inclusion within the Dark Tetrad as a unique construct but with some conceptual overlap with psychopathy.
