“…The internal consistency of some of the intentions subscales fell below the generally recommended standard of 0.7. However, it must be considered that these are largely 3‐ and 4‐item scales, and alpha tends to increase with the number of items (e.g., Abdelmoula, Chakroun, & Akrout, ). Furthermore, it is generally accepted that a lower alpha value will tend to under‐ rather than overestimate associations with the dependent variables.…”

Objective We aimed to identify Australian adults’ current level of confidence and intentions to help a person close to them in distress or at risk of suicide to inform the content and targeting of suicide prevention messages aimed at family and friends of those at risk. Methods We conducted a nationally representative computer‐assisted telephone survey of confidence and intentions to help someone in distress or at risk of suicide (n = 3,002). We used logistic regression to determine whether sociodemographic and exposure variables predicted confidence and intentions to help. Results Confidence to help was high. About half of the respondents had intentions inconsistent with best practice. Listening and talking, and encouraging the person to seek professional help were the most common types of intended helping actions. Intentions to ask suicide risk assessment questions were least common. Men were more likely than women to have intentions to carry out nonrecommended actions, and less likely to have intentions to carry out recommended actions. Conclusions Suicide prevention messaging aimed at family and friends could encourage them to ask direct questions about suicide risk and could include messages about “what not to do.” Suicide prevention messages aimed specifically at men are indicated.

Belief in suicide prevention myths and its effect on helping: a nationally representative survey of Australian adults

et al. 2020

Background Debunking suicide myths, such as ‘asking someone about suicide could make them start thinking about it’ is a common strategy in suicide prevention education. However, there has been little research investigating the relationship between suicide myths and helping behavior toward people at risk of suicide. We aimed to identify sociodemographic characteristics associated with belief in eight common suicide myths and the associations between beliefs in these myths and helping intentions and behaviors toward a family member or friend in severe distress or at risk of suicide. Methods We conducted a random digit dial (mobile and landline) survey of 3002 Australian adults. We asked respondents about their beliefs in suicide myths, intentions to help a person in severe distress or at risk of suicide presented in a vignette, and helping actions taken toward such a person in the last 12 months. We weighted this data to be representative of the Australian population. Regression analyses were undertaken to determine associations between sociodemographic and exposure characteristics and beliefs in suicide myths, and between beliefs in myths and helping intentions and behaviors. Results Being male, speaking a language other than English at home and being over 60 years were associated with the strongest beliefs in suicide myths. The strongest and most consistent associations were found between belief in the myth ‘asking someone about suicide could make them start thinking about it’, risk assessment intentions and behaviours and intentions to undertaken actions not recommended for suicide prevention. Conclusions Identifying those sociodemographic groups most likely to believe in suicide myths allows targeted intervention for suicide prevention education ‘debunking’ suicide myths. By isolating those myths that are most commonly believed, and their specific effects on helping intentions and behaviors, suicide prevention educators can target these specific myths to have the most effect on helping behavior. Our findings suggest that targeting the myth ‘asking someone about suicide could make them start thinking about it’ may have the greatest effects on helping behavior, and that men, those aged over 60 years and those speaking a language other than English at home could most benefit from myth ‘debunking’.

“…The questionnaire took its final form after the modifications were made. Abdelmoula et al ( 2015 ) confirmed that sample size has a positive effect on reliability. Also, some other researchers have found that the sample size has an effect on reliability (Bonett, 2002 ; Charter, 2003 ; Duhachek et al, 2005 ; Helms et.…”

Mobile technology usage in early childhood: Pre-COVID-19 and the national lockdown period in North Cyprus

2021

View full text Add to dashboard Cite

COVID-19 has affected North Cyprus since the beginning of March 2020. On March 10 th 2020, the council of ministers in North Cyprus announced a lockdown and listed some restrictions to prevent the spread of the virus; schools and entertainment centres were closed, and children had to spend most of their day at home. This study aims to examine the use of mobile technology before and during the COVID-19 lockdown period by children aged three to six, based on parents' opinions. This is a descriptive study with a sample of 319 parents. Data and demographic information were collected with a questionnaire and analysed with SPSS (24.0). Comparing the duration of mobile technology device usage before the pandemic and during the lockdown period, an increase is evident, as expected. Of note, when compared to the pre-pandemic period, it is found that there is a decrease in the rate of mobile technology device usage for video viewing during the lockdown period. The findings also suggest that children mostly first experienced mobile technology devices in some way before 36 months of age. This study has determined that most children do not have their own mobile technology device.
