Study setting and design
The study was a cross-sectional descriptive study, involving 253 respondents (150 males and 103 females), aimed at investigating the implications of education level and relationship status on level of awareness on mental healthcare and mental health state among low income earners in Western Uganda.
Study participants
The present study deployed simple random sampling technique, among low income earners between 18 and 65 years of age living and or working within Ishaka municipality in Bushenyi district of Western Uganda who gave their consent to be part of the study. Those outside the age required for the study were excluded from the study. Low income earners were individuals who depend on day to day business activities for their livelihood such as “boda” riders (cyclist), mobile money stand agents, traders and the like [16].
Sample size determination
Since the study population is infinite, the study adopted the sample size necessary for estimating a population proportion of a small infinite population with (1-α)100% confidence and error no larger than e [17]:
m = is the sample size necessary for estimating the proportion p for a small infinite population, and n = correction to represent a finite population.
Let α = 5, therefore e = 0.05
Where p = the proportion of low-income earners in Bushenyi
However, available data only represents the poverty index of Bushenyi of 29.5% as at 2006 [18];
p = assumption that proportion of low-income earners will be around 50% of poverty index = 0.295 × 0.5 = 0.1475
Therefore,
The sample Size for low-income earners was 193, and the researcher assumes an attrition rate of 10% (19); therefore, workable sample size was 212. In the end 280 potential respondents were approached, out of whom 27 of them declined. Therefore, the sample size is 253.
Measurements and Data collection methods
A closed-ended questionnaire was used to collect data from the respondents who met the inclusion criteria for the study. The questionnaire had questions covering five different areas of the study; sociodemographic (sex, educational status and relationship status), awareness on mental healthcare, anxiety, anger and depression. Awareness of mental health care was assessed using simple questions. Anxiety was assessed using a modified generalized anxiety disorder (GAD-7) item tool [19]. Anger was assessed using a modified Spielberger’s State-Trait Anger Expression Inventory-2 (STAXI-2) [20]. Depression was assessed using a modified Beck Depression Inventory (BDI) [21]. Responses from the different components of the questionnaire were assigned scores. A Google format of the questionnaire was used to minimize physical contact and also maintain social distancing according to the guidelines by WHO and Ministry of Health in Uganda. Respondents who could not understand the questions clearly had the questions interpreted in local language for them by team members who can communicate effectively in the local language. The internal consistency for the different segments of the questionnaire, (awareness on mental healthcare, GAD-7, STAXI-2 and BDI) Cronbach's α=0.85, 0.79, 0.84 and 0.75 respectively.
Data management and organization
The data obtained from the survey was entered into Microsoft excel (2016) and scores were assigned to each option as follows: Mental Health Care Awareness (Q5 – Q10): Numerical values – Mental Health Awareness [Correct response = 1, Incorrect response = 0]. Modified GAD Assessment of Anxiety (Q11 – Q16): Numerical values – Multiple response [For each option selected = 1, indifferent = 0]. Modified STAXI-2 Assessment for Anger (Q17 – Q23): Numerical values – Multiple response [For each option selected = 1, indifferent = 0]. Modified BDI Assessment for Depression (Q24 – Q30): Numerical values – Single graded response [Highest grade of 3, indifferent = 0]. However, the data collected were assessed for completeness and responses failing to meet the 75% cut-off (on all valid questions) were excluded (Figure 1).
For questions on awareness level, every correct response was assigned (1) and incorrect response was assigned (0). The scores of the multiple options for the modified GAD, and STAXI-2 were obtained by assigning one (1) mark per response. While BDI had four (4) options graded as 3, 2, 1 and 0 (for indifferent). For specific graded questions (Yes, sometimes, or No), scores; 2, 1, 0 were assigned and all questions in this form were cumulated (per row) and the averages were obtained by summing all scores (qt) and dividing the number of questions (n) for each section. On the other hand, the obtained scores for each individual in the different segment was then converted to percentage, so as to get the mean percentage score for awareness, anxiety, anger and depression.
Data Analysis
The data was transferred to Graphpad Prism version 6 and Minitab® 18.1 (Minitab, Inc. 2017) for analysis. The relationship between educational status and relationship status with awareness, anxiety, anger and depression level we examined using Spearman Rho correlation, then all significant correlates were regressed using system-assisted regression model. All analyses were performed at 95% confidence level and p-values less than 0.05 were taken to be significant.
