Many students are not aware that research design can be simultaneously described in many different ways; for example, a drug trial may be described as being prospective, longitudinal, randomized, double-blind, and placebo-controlled, all at the same time. This article provides examples to explain how studies can be simultaneously prospective and cross-sectional, prospective and longitudinal, retrospective and cross-sectional, and retrospective and longitudinal. The term prospective indicates that the study data are newly collected, whereas the term retrospective indicates that the study data already exist in records and merely need to be extracted for study. The term cross-sectional indicates that the study subjects are studied on a single occasion; that is, at a single point in time. The term longitudinal indicates that the study subjects are followed up and that there is almost always more than one time point at which the subjects are assessed. This article also describes unusual designs, such as cross-sectional randomized controlled trials and retrospective studies with prospective data ascertainment.

This investigation focuses on the question whether assessments of the development of internalizing behavior from childhood to adolescence are affected by the kind of research design (longitudinal versus cross-sectional). Two longitudinal samples of 432 second-graders and 366 fourth graders participated in a longitudinal study with subsequent measurements taken 1, 2, and 3 years later. A third sample consisting of 849 children covering the same range of grades participated in a cross-sectional study. The results show that the development of internalizing symptoms in girls – but not in boys – varies systematically with the research design. In girls, there is a decrease of internalizing symptoms (especially between the first two timepoints) in the longitudinal assessment, which may reflect, for example, the influence of strain during the first testing situation. Both longitudinal trajectories converge to a common trajectory from grade 2 to grade 7 when controlling for this “novelty-distress effect.” Moreover, when we control this effect, the slight but significant decrease characterizing the common trajectory becomes similar to the one obtained in the cross-sectional study. Therefore, trajectories based on longitudinal assessments may suggest more changes with regard to internalizing symptoms over time than actually take place, while trajectories based on cross-sectional data may be characterized by an increased level of internalizing symptoms. Theoretical and practical implications of these results are discussed.

Background: Future health-care professionals face stress both during education and in later professional life. Next to educational trainings, many students are forced to assume part-time employment. Objective: Applying the Job Demands-Resources Model to the educational context, we investigate which role part-time employment plays next to health-care professional students’ education-specific demands and resources in the prediction of perceived stress. Method: In this cross-sectional study, data from N = 161 health-care students were analysed, testing moderation models. Results: Education-specific demands were associated with higher and education-specific resources with lower amounts of perceived stress. Part-time employment functioned as moderator, i.e. demands were less associated with stress experiences in students who were employed part-time. Conclusion: Identifying part-time employment as a resource rather than a demand illustrates the need to understand students’ individual influences on stress. Both educators and students will benefit from reflecting these resources to support students’ stress management.

Knowledge and practice of public, especially patients about eye diseases are important to reduce magnitude of human blindness. Vision and sight are very essential because they allow us to connect to each other’s. In accordance to the recently published data; the estimation of 253 million people lives with vision impairment, 36 million are blind and 217 million suffer from moderate to severe vision impairment. A descriptive cross-sectional study was conducted at Shahid Dr. Aso Hospital in Sulaimani city-Iraq, from April to August 2017 by face-to-face interview through close ended questionnaire for data collecting. All data were analyzed by Statistical Package for Social Sciences version 22.0 software. P-value of < 0.05 was considered as a statistically significant. A total of 430 patients were randomly chosen to participate in the study. They were 254 (59.1%) males and 176 (40.9%) females. 76.7% of respondents was worrying about vision loss, 0.7% was worrying about hair loss. Of the participants, 32.8% was with a good knowledge level and 40.5% was with a poor knowledge level, as well as 3.1% was in a good practice and 58.8% was in a poor practice level. Female knowledge mean score was 9.53±4.96 and male knowledge mean score was 8.42±5.45, the practice mean score of males was 4.33±1.96 and mean practice score of females was 4.13±1.93. The study data indicate the worrying of participates about vision loss is in the highest proportion and the awareness and practice of patients about eye diseases is unsatisfactory. Health education campaigns are needed to improve personal awareness about vision related problems and for better eye health.

Background: The global advocacy for Direct Access (DA) and Patients’ Self-Referral (PSR) to physiotherapy is consistent with the quest for promoting professional autonomy and recognition. It was hypothesized in this study that the attainment of this clarion call in Nigeria may be hamstrung by challenges similar or different from those reported in other climes. Objective: This study assessed the perception of DA and PSR among Physiotherapists (PTs) in South-West, Nigeria. Methods: One hundred PTs from ten purposely selected public-funded out-patient facilities from South-West, Nigeria responded in this cross-sectional study, yielding a response rate of 75% (100/150).  A previously validated questionnaire for World Confederation of Physical Therapists (WCPT) on the global view of DA and PSR for physical therapy was used in this study. Data was analyzed using descriptive statistics. Results: There was a high awareness on legislation regulating practice (91%) and scope (84%) of the profession. Respondents assert that the extant legislation allows for DA (49%) and PSR (97%). However, 40% of the respondents opined that the baccalaureate qualification of PTs was inadequate for competence in DA and PSR; and a post-professional residency programme was mostly recommended (52%). Public support for DA and PSR to physiotherapy was rated more than the advocacy role of the Nigeria Society of Physiotherapy (60% vs. 40%). Physicians’ (71%) and politicians’ (65%) views were rated the major barrier to achieving DA and PSR status in physiotherapy. Similarly, physicians’ (90%) and politicians’ (88%) support was perceived as the major facilitator.  Conclusion: Physiotherapy practice in Nigeria has the semblance of autonomy in DA and PSR but is devoid of legislative support. Most Nigerian physiotherapists assume professional autonomy but were not aware of the lack of legal support for DA and PSR. The current entry-level academic curricula were considered to be deficient and inadequate for autonomous practice in Nigeria.  Physicians and politicians were the most important barrier or facilitator to achieving legal support for DA and PSR in physiotherapy in Nigeria.
