Study design and sampling.
This cross-sectional study was conducted between May 10 and 20, 2020, using an online-based questionnaire created on Google forms. Due to the government-mandated sanitary lockdown, the snowball sampling technique was used to distribute the survey to participants through social media platforms and WhatsApp groups. All adults living in Lebanon, with access to the internet, were eligible, regardless of their age, socioeconomic status, race, ethnicity, nationality, sex, religion, geography, ability, and culture. A total of 502 respondents filled out the questionnaire that required between 15 and 20 minutes to complete.
Minimal sample size calculation.
The minimum sample size was calculated using the G-Power software, version 3.0.10.
The calculated effect size was 0.0526, expecting a squared multiple correlation of 0.05 (R2 deviation from 0) related to the Omnibus test of multiple regression. The minimum necessary sample was n = 454, considering an alpha error of 5%, a power of 80%, and allowing 25 predictors to be included in the model.
Questionnaire.
The online questionnaire was available in Arabic, the native language in Lebanon. It consisted of three parts. The first part assessed the socio-demographic features of the participants, such as age, gender, marital status, educational level, employment status, region, current household monthly income, divided into five levels, according to the official exchange rate (1 USD = 1500 LBP): no income, low < 675,000LBP (450 USD, the official lowest wage in Lebanon), moderate 675,000–1,500,000LBP (450-1,000 USD), high 1,500,000–3,000,000 LBP (1,000–2,000 USD), and very high income > 3,000,000 LBP (2,000 USD). It also included questions about medical coverage, smoking, alcohol consumption, self-perception of the financial situation, having been infected or in contact with people contaminated with coronavirus, and physical activity before and during the COVID-19 pandemic. Violence was self-evaluated by the answer to the following questions with four possible answers: 1-Yes; 2-No; 3-No answer; 4-Does not apply:
Is there any form of verbal violence in your home? Is there any form of physical violence in your home? Is there any form of sexual violence in your home? Is there any form of any other type of violence in your home?”.
The second part of the questionnaire consisted of a set of 20 work-related questions, addressed to working people and those seeking employment and aiming to explore to what extent their current employment was affected by either the economic crisis or the COVID-19 pandemic. Examples of the questions asked: Do you have to go out to make a living despite the sanitary lockdown? Are you able to apply social distancing while working (1.5-2m safety distance)? Did your company change the working hours because of the economic crisis or the COVID-19 pandemic? Has your salary/income been affected by the economic crisis or the COVID-19 pandemic? Are you worried about the long-term impact of the economic crisis or the COVID-19 pandemic on your business/job? Did the economic crisis or the COVID-19 pandemic result in decreasing the salaries of employees? Did the economic crisis or the COVID-19 pandemic cause the dismissal of some employees? What were the criteria used to lay-off employees?
Finally, the third part of the questionnaire included several validated scales:
The fear of COVID-19 scale.
This 7-item tool measures the extent of fear of the COVID-19 in adults [23]. The total score, ranging from 1 to 35, is calculated by summing the answers to all questions graded from 1 (strongly disagree) to 5 (strongly agree) on a 5-point Likert scale. Higher scores indicate a greater fear of COVID-19 (αCronbach = 0.893).
The Beirut Distress Scale-22 (BDS-22).
The BDS-22, validated in Lebanon [24], evaluates the level of stress in the general Lebanese adult population. It consists of 22 questions exploring six different domains: depressive symptoms, demotivation, psychosomatic symptoms, mood deterioration, intellectual inhibition, and anxiety. Responses are rated on a 4-point Likert scale from 0 (not at all) to 3 (all of the times), with higher scores indicating higher levels of stress. (αCronbach = 0.965).
The Lebanese Anxiety Scale-10 (LAS-10).
The LAS-10 is a 10-item scale validated in Lebanon [25] used to screen for anxiety in the general Lebanese adult population. Questions 1 to 7 are scored on a 5-point Likert scale from 0 (not present) to 4 (very severe), whiles items 8–10 are graded on a 4-point Likert scale from 1 (never/almost never) to 4 (almost always). Higher scores indicate higher anxiety. The Cronbach’s alpha for this scale was 0.919.
The of Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5).
This 20-item tool evaluates the 20 DSM-5 symptoms of PTSD in the past month. It is available in Arabic language as was validated in Syria [26]. Responses are rated on a 5-point Likert scale from 0 (not at all) to 4 (Extremely). The total symptom severity score (range 0–80) is obtained by summing the responses for each of the 20 items. Higher scores reflect higher symptoms resulting from a stressful experience (αCronbach = 0.971). In this manuscript, “PTSS” is used for both the symptoms and the disorder, as the questionnaire evaluated the symptoms more likely than the disorder.
The Lebanese Insomnia Scale (LIS-18).
This 18-item tool, recently validated in Lebanon [27], is used to screen for insomnia. Answers are graded on a 5-point Likert scale from 1 (Never) to 5 (Always), with higher scores indicating higher insomnia. (αCronbach = 0.847).
The Family APGAR Index.
This instrument evaluates satisfaction with the global family function [28]. It consists of five questions graded on a 3-point Likert scale: 0 (hardly ever), 1 (some of the time), and 2 (almost always). Each corresponds to a component of family function, i.e., Adaptation, Partnership, Growth, Affection, and Resolve (APGAR). The total, ranging from 0 to 10, is obtained by summing the answers to all items. Higher scores indicate higher satisfaction with family function (αCronbach = 0.927).
The World Health Organization-Five Well-Being Index (WHO-5).
This short version, validated in Lebanon [29], consists of five questions graded from 0 to 5 assessing mental well-being in the past month. The total score ranges from 0 to 25; higher scores indicate a better mental well-being (αCronbach = 0.796).
The InCharge Financial Distress/Financial Well-Being Scale (IFDFW).
This tool includes eight items assessing the perceived financial distress/financial well-being on a 1-to-10 linear scale [30]. Lower scores reflect higher financial distress and lower well-being (αCronbach = 0.925). Since this tool is copyrighted, written permission was obtained from the authors to use it and validate it in Lebanon.
Translation Procedure and Piloting.
Three of the scales (fear of the COVID-19, the Family APGAR Index, and the IFDFW), not validated and available in Arabic, were translated into this language. Three authors performed the forward translation, and the other three, the back translation. Discrepancies between original English versions and translated ones were resolved by consensus. The final version was pilot-tested on ten people unfamiliar with the study. The final dataset did not include their answers.
Statistical Analysis.
Data were collected using Google Forms, a tool that automatically generates an Excel database, then transferred to IBM SPSS®, version 23.0 for analysis. Prior to the analysis, data were weighted according to gender, age, and dwelling region, based on the figures of the Central Administration of Statistics [31]. In the descriptive analysis, frequencies and percentages were used for categorical variables, and means and standard deviations for quantitative variables. For dependent variables (BDS-22, LIS-18, LAS-10, PCL-5, and WHO-5), the distribution was considered normal based on the visual inspection of the histogram, and the skewness and kurtosis (lower than 1). These conditions are compatible with normality in a sample size higher than 300 [32].
For the bivariate analysis of continuous variables, the Student’s T-test was used to compare the means between two groups, after checking for homogeneity of variances using the Levene’s test. In case the variances were not homogeneous, the corrected T-Test was applied. The Chi-square test was used for dichotomous and multinomial variables. When calculated values per case were < 5, the Fisher exact test was performed. In all cases, a p-value lower than 0.05 was considered significant.
Afterward, a multivariate analysis employing the General Linear Model was performed, using the mental health-related dependent variables; the ENTER method was applied to come up with the appropriate model with proper assumptions. This method allowed to calculate the estimated marginal means for mental health measures among men and women, and among subjects with and without declared domestic violence.
