“…[ 16 ] However, although previous studies tried to increase the response rate by sending reminders and the giving of modest incentives, they did not achieve 70%. [ 17 18 19 ] We tried to avoid low response, which can introduce bias into results, by sending five reminders to participants. [ 20 ] The reasons for nonresponders and the lack of participation were not investigated as that was beyond the scope of this study and could have breached confidentiality.…”

BACKGROUND: A good night sleep is essential for good health since it supports proper brain functions and its ability to make decisions and to learn and remember new information. The objectives of this study were to assess the prevalence of sleep deprivation (SD) and its effects on the performance of family medicine residents in Riyadh. MATERIALS AND METHODS: A cross-sectional study design was based on an informative-validated self-assessment questionnaire, especially designed by the Medical Council of Canada, to assess the performance of family medicine physicians. Ethical approval was obtained from the institutional review board. Data was analysed using SPSS; initial analysis included computating frequencies and percentages. Odds ratios were calculated for association between. RESULTS: Of the total 258 respondents, 32% had low performance, and 41.5% of the sample suffered from SD, with a male/female ratio of 1:1. There were no significant differences between residency level (R1, R2, R3, and R4) and the average number of sleeping hours. However, 45.5% of R1, 47.8% of R2, 32.4% of R3, and 41.5% of R4 suffered from SD. The data showed a significant difference between the performance and the average number of hours of sleep of the respondents on a typical day. SD was associated with the low performance of 48.6% of subjects compared to 18.3% in those who slept for 7–9 h (aOR=3.96). CONCLUSION: SD negatively affects the performance of family medicine residents. There was no statistically significant difference between males and females in performance. The center for residents' training should consider adequate sleep as essential for the promotion of health and performance.

“…Substitutes were matched based on age, sex and geographical location, in substitution phases. In order to increase the response rate, we sent a reminder for participants who did not respond within ten days as recommended by several studies 25 , 26 . Out of 1,512 invited, 543 participants responded to the survey.…”

Valid and reliable measurement of an individual’s knowledge and risk perception is pivotal to monitor and evaluate the effectiveness of interventions aimed at preventing cardiovascular diseases (CVDs). The recently developed Attitudes and Beliefs about Cardiovascular Disease (ABCD) knowledge and risk questionnaire is shown to be valid in England. In this study, we evaluated the psychometric properties of the modified and Dutch (Flemish)-translated ABCD questionnaire using both the classical test and item response theory (IRT) analysis. We conducted a community-based survey among 525 adults in Antwerp city, Belgium. We assessed the item- and scale-level psychometric properties and validity indices of the questionnaire. Parameters of IRT, item scalability, monotonicity, item difficulty and discrimination, and item fit statistics were evaluated. Furthermore, exploratory and confirmatory factorial validity, and internal consistency measures were explored. Descriptive statistics showed that both the knowledge and risk scale items have sufficient variation to differentiate individuals’ level of knowledge and risk perception. The overall homogeneity of the knowledge and risk subscales was within the acceptable range (> 0.3). The exploratory and confirmatory factor analyses of the risk scale supported a three-factor solution corresponding to risk perception (F1), perceived benefits and intention to change physical activity (F2), and perceived benefit and intention to change healthy dietary habit (F3). The two parametric logistic (2—PL) and rating scale models showed that the item infit and outfit values for knowledge and risk subscales were within the acceptable range (0.6 to 1.4) for most of the items. In conclusion, this study investigated the Dutch (Flemish) version of the ABCD questionnaire has good psychometric properties to assess CVD related knowledge and risk perception in the adult population. Based on the factor loadings and other psychometric properties, we suggested a shorter version, which has comparable psychometric properties.

“…The generalizability of the present study is further limited by biases that may have been introduced by our sampling method: sending out email invitations, advertising our study in person at local support groups (this accrued the smallest return), and advertising it on social media. A number of studies have documented that women are generally more likely than men to engage with online surveys [82][83][84], and our disproportionate ratio of females to males would seem consistent with this observation, despite its incongruence with the elevated ratio of males to females diagnosed with autism [85,86]. Notably, studies concerning mental health in non-autistic people have linked the lower up-take by men to the greater stigma that men experience around discussing and seeking help for mental ill-health [87][88][89][90][91][92].…”

Links between self-injury and suicidality in autism

et al. 2020

Background: Autistic individuals without intellectual disability are at heightened risk of self-injury, and appear to engage in it for similar reasons as non-autistic people. A wide divergence of autistic perspectives on self-injury, including those who frame it as a helpful coping mechanism, motivate investigating the link between self-injury, suicide ideation, and attempts which has been reported in typically developing individuals. Method: One hundred three autistic participants completed the Non-Suicidal Self-Injury Assessment Tool (NSSI-AT), the Suicide Behaviors Questionnaire (SBQ-R), and the Interpersonal Social Evaluation List (ISEL-12) across two online studies. Logistic regression was conducted to predict self-harming status via responses to questions on suicidality, and to predict whether certain self-injurious behaviors, including cutting, were especially associated with suicide ideation and attempts. Non-parametric correlation analysis examined relationships between suicide ideation/ attempts and other variables that might characterize self-harmers especially at risk of suicidality. These included perceived access to social support, purposes or reasons for self-injury, the number of different self-injurious behaviors engaged in, the duration and lifetime incidence of self-injury, and the individual's feelings about their self-injury. Results: While self-injuring status was significantly predicted by responses to a question on suicide ideation and attempts, there was no relationship between suicide ideation/attempts and a participant's personal feelings about their self-injury. The method of cutting was also predicted by suicide ideation and attempts, though other methods common in autistic people were at borderline significance. Use of self-injury for the regulation of low-energy emotional states like depression, for self-punishment or deterrence from suicide, and for sensory stimulation, was associated with suicide ideation and attempts, as was the number of self-injurious behaviors engaged in. There was no significant relationship between suicide ideation/attempts and the duration and lifetime incidence of self-injury or social support. Conclusions: These preliminary data suggest that while individuals might frame their self-injury as a positive or neutral thing, there remains a concerning relationship between self-injury and suicidality which exists regardless of individual feelings on self-injury. This is consistent with the theoretical perspective that self-injury can be a "gateway" through which individuals acquire capability for lethal suicidal behaviors. The data highlight that particular methods (cutting) and reasons for self-injury may be of significant concern, but this information, which might be of extreme value for clinicians, requires further investigation and validation.
