Introduction

Globally, more than 450 million people suffer from a mental or behavioral disorder; the total number of people living with depression and anxiety disorders in the world is estimated to 322 million (4.4%) and 264 million (3.6%), respectively. These disorders are common mental disorders and suicide is common in mental disorder especially in depressive patients [1].

There are over 35,000 deaths per year in the United States attributed to suicide and is currently ranked the tenth overall cause of death in the United States. Almost 95% of all persons who commit or attempt suicide have a diagnosed mental disorder. Psychiatric disorders like depressive disorders account for 80% of this figure and schizophrenia accounts for 10%. Psychiatric patients’ risk for suicide is 3 to 12 times that of non-patients, but the degree of risk varies, depending on age, sex, diagnosis, and patient status [2]. Suicidal ideation refers to thoughts of serving as the agent of one’s own death and it may vary in seriousness depending on the specificity of suicide plans and the degree of suicidal intent [3].

In America, the study revealed that suicidality was elevated in patients who reported depression or anxiety (AOR = 1.10, P = 0.03), and violent behavior (AOR = 2.59, P < 0.001) [4]. A similar study was done in USA revealed that anxiety is a predictor of suicide ideation (AOR = 1.49, 95% CI 1.18–1.88, P < 0.01). Also disorder like Post-traumatic stress disorder, PTSD (AOR = 4.21); generalized anxiety disorder, GAD (AOR = 1.70, 95% CI 1.18–2.46, P < 0.01); specific phobia (AOR = 1.45, 95% CI 1.16–1.81, P < 0.01); and social anxiety disorder, SAD (AOR = 1.38, 95% CI 1.10–1.72, P < 0.01) were also significant predictors of suicide ideation [5].

A study done in America, Washington DC, revealed that PTSD (AOR = 4.45, 95% CI 2.58–7.67); major depressive disorder, MDD (AOR = 3.63, 95% CI 2.01–6.40) and PTSD with comorbid mental disorder (AOR = 5.71, 95% CI 2.09–23.85) were risk factors for suicidal ideation at P < 0.01 [6]. Another study done in Iran, Tehran, reported hypomanic/manic symptoms (95% CI 0.86–0.98, P = 0.007) and depression (95% CI 0.87–0.98, P = 0.004) were significantly associated with current suicidal ideation [7].

A study conducted in China showed that GAD (AOR = 1.15 95% CI 1.09–1.22), other psychiatric diagnoses including MDD (AOR = 11.9, 95% CI 6.6 ± 21.5, P < 0.001) and anxiety disorders (AOR = 8.45 95% CI 15.23–22.75), and bipolar disorders (AOR = 4.42, 95% CI 8.23–12.09) were risk factors that associated with suicidality did not receive MDD diagnosis, whereas risk of suicidality in patients diagnosed with MDD were: female (AOR = 2.28, 95% CI 1.0–5.1, P = 0.042) and had anxiety disorder (AOR = 2.24, 95% CI 1.17–4.28, P = 0.015) [8].

Study in Lithuania showed that suicidal ideation was independently associated with the use of antidepressants (AOR = 5.4, 95% CI 1.7–16.9) and with current major depressive episode MDD (AOR = 2.90, 95% CI 1.5–5.8) at P < 0.05 [9]. In Singapore, the study showed that suicidal ideation was significantly associated with GAD (AOR = 3.7, 95% CI 1.1–12.3, P = 0.032) [10] and a study done in Helsinki, Finland, revealed that suicidal ideation was independently predicted by severe depressive disorder (AOR = 4.980, 95% CI 1.856–13.364, P = 0.001) and bipolar disorder type II/not otherwise specified (AOR = 3.975, 95% CI 1.260–12.542, P = 0.019) [11].

A study conducted in Japan showed that moderate (AOR = 3.98, 95% CI 1.63–9.72, P < 0.01) or more severe depression (AOR = 59.62, 95% CI 8.14–436.80, P < 0.01) was associated with current suicidal ideation [12], whereas another study in that country, Tokyo reported that panic disorder with agoraphobia (AOR = 2.405, 95% CI 1.269–3.492, P = 0.004); obsessive compulsive disorder, OCD (AOR = 2.912, 95% CI 1.511–5.612, P = 0.001); PTSD (AOR = 2.048, 95% CI 1.153–3.637, P = 0.014) and specific phobia (AOR = 2.038, 95% CI 1.037–4.005, P = 0.039), and borderline personality disorder (AOR = 2.523, 95% CI 1.186–5.366, P = 0.016) were predictive of suicide behavior (SB) as a whole and appeared to have predictive value for SB, respectively [13].

Another study in Eastern Nepal showed that suicidal ideation was independently related to a diagnosis of depression (AOR = 24.68, 95% CI 2.127–286.273, P = 0.013) [14]. According to a study done in Jena, Germany, showed that comorbid depression disorder (AOR = 2.33, 95% CI 1.12–4.84, P = 0.023) and depression (AOR = 1.22, 95% CI 1.13–1.32, P = 0.0001) predicted concurrent suicidal ideation [15].

In South Africa, the study showed that both death and suicidal ideation were significantly associated with a primary diagnosis of depressive disorder (AOR = 4.72, 95% CI 1.29–17.24, P = 0.019 and 6.54, 95% CI 2.45–17.54, P < 0.001, respectively). Factors that uniquely predicted death ideation was: primary diagnosis of bipolar disorder (AOR = 4.61, 95% CI 1.43–14.72, P = 0.010); and with suicidal ideation being uniquely predicted by a primary diagnosis of borderline personality disorder (AOR = 7.14, 95% CI 1.34–38.46, P = 0.021) [16].

A study conducted in Addis Ababa, Ethiopia, revealed that episodes of no positive symptoms (delusion, hallucination) (AOR = 0.378, 95% CI 0.209, 0.683, P value < 0.01), and comorbid depression with schizophrenia (AOR = 5.41, 95% CI 2.764–10.60, P < 0.001) had association with suicidal ideation [17]. Another study done in Jimma, Ethiopia, showed that MDD (AOR = 4.48, 95% CI 1.95–10.26, P = 0.00), and presence of psychiatric diagnosis (like anxiety, other psychiatry disorders) (AOR = 3.84 and 95% CI 1.16–12.67, P = 0.03) were the independent predictors of suicidal behaviors [18].

Identifying determinants of suicidal ideation will be helpful to mental health professionals for routine assessing, designing effective prevention and intervention methods that are important in preventing the effect of suicidal ideation and save the patient’s life.

Methodology

Study areas and period

This study was conducted in 2019 at Mekelle town, psychiatric clinics (Ayder Comprehensive Specialized Hospital and Mekelle General Hospital). According to the Ethiopian central statistical agency report; the total population in 2011 has been 367,470 (186,045 males and 181,376 females), which is located in Tigray regional state 783 km away from Addis Ababa, the capital city of Ethiopia to the North. Psychiatric services are given by psychiatrists, general practitioner, M.Sc in mental health, B.Sc in psychiatric nursing and clinical psychologists. More than 30 health professionals work in a psychiatry clinic, out of them, two psychiatrists and two clinical psychologists. The current flow of psychiatric patients on average was 946 and 337 patients per month in Ayder Comprehensive Specialized Hospital and Mekelle General Hospital, respectively. Ayder Comprehensive Specialized Hospital had 24 beds for inpatient services, but Mekelle General Hospital has no inpatient service. The study period was from April 15 to May 30, 2019.

Study design

An institutional-based unmatched case–control study was conducted.

Source population and study population

Source population

All psychiatry outpatient unit visitors were in Mekelle town, psychiatric clinics, Tigray, Northern Ethiopia.

Study population

All psychiatric sampled outpatient unit visitors were in Mekelle town, psychiatric clinics, Tigray, Northern Ethiopia.

Eligibility criteria

Inclusion criteria

  • Case: psychiatry outpatient unit visitors, clients who had suicidal ideation (scored 8 and above out of 18) and aged 18 years and above, patients attending treatment at psychiatry clinic during the data collection period were included in the study.

  • Control: psychiatry outpatient unit visitors, clients who had no suicidal ideation, responded to suicidal behavior questions and scored less than 8 out of 18.

Exclusion criteria

Clients who were unable to communicate and unable to sign verbal informed consent and those who had decision incapacity were not be included in the study.

Sample size and sampling procedure

Sample size

The sample size was calculated using a double proportion formula taken from a study conducted in Jimma showed that one of the risk factors for suicidal ideation was having a family history of mental illness (AOR = 2.25) and P = 40% [18]. Based on these assumptions, the sample size was calculated as follows: two-sided confidence level = 95%, power = 80%, ratio of cases to controls = 1:2 and odds ratio = 2.25. Then, the desired sample size using Epi info Stata calculation, odds ratio = 1:2, case = 74 and control = 147, the final sample size was 221 (Table 1).

Data collection procedure

Face-to-face interview method using a structured questionnaire was used in this study to identify determinants of suicidal ideation such as (1) sociodemographic information, (2) biopsychosocial (3) suicidal ideation, (4) suicidal attempts and its methods. Also, the chart was reviewed to check the psychiatric and other medical illness diagnoses.

The SBQ-R is a self-report measure of suicidal ideation. This shortened version of the SBQ consists of four questions and used a Likert type scale to assess suicidal behavior history, current suicide status and self-appraisal and expectancies about the future likelihood of engaging in suicidal behavior. The magnitude of overall suicidal ideation and behaviors (as defined by SBQ-R a total score ≥ 8 for adult clinical population) and the total score ranges from 3 to 18.

Data were collected by five B.Sc psychiatry professionals having a previous experience of data collection. The principal investigator checked the filled questionnaires for consistency and completeness daily. The questionnaire was translated from English to Tigrigna language by expert and retranslated to English by another proficient in English. This primary version was made to compare with the original English version to resolve inconsistencies and then the data collectors, who are Tigrigna native speakers, collected data in the Tigrigna questionnaire.

Study variables

Dependent variables

Suicidal ideation.

Independent variables

Socio-demographic characteristics, medical and substance-related characteristics, mental disorders, illness and hospital related characteristics, psychosocial-related characteristics, suicidal attempt-related characteristics.

Operational definitions

Suicidal ideation: after the onset of the illness, the patient experiences the degree of having wished, ideation, expectancies about the future likelihood of engaging in suicidal behavior, and plan to kill oneself, and based on SBQ-R scale scores ≥ 8 from 18, at least 2 points out of 4 from suicidal thought or attempt question 1 and the total scale scores range from 3 to 18 [19].

Data quality assurance

The pre-test was conducted on a sample of 5% (7 controls and 4 cases) of the total study population in Wukiro General Hospital before 2 weeks of data collection and a common understanding was reached between the data collectors to avoid inter-rater variability. The pre-test questionnaires were not included in the analysis as part of the main study. Data collection was collected within 30 working days. Regular supervision by the principal investigator was carried out. Each day during data collection, filled questionnaires’ were checked for completeness and consistency. Incomplete and unclear questionnaires were returned to the data collectors to get it corrected.

Data analysis procedure

After data collection, filled questionnaires were coded. The data were entered using Epi data version 4.2 statistical software in order to minimize error that occurs during data entry and exported to SPSS; and analyzed using SPSS version 23. Data cleaning was performed to check for frequencies, accuracy, and consistencies and missed values and variables. The finding of this study was presented using text, figure and tables form from the result of frequencies and crosstabs.

A bivariate logistic regression model analysis was done to see the association between the explanatory and outcome variables. Henceforth, multivariable logistic regression analysis was employed by selecting only variables with a P-value < 0.25 in the bivariate analysis. The odds ratio with 95% CI was used to measure the strength between dependent and independent variables at P-value < 0.05 to determine the level of statistical significance. Variables with the P-value less than 0.05 (i.e., 95% CI) in multivariate regression were declared to be potential predictors for suicidal ideation.

Suicide assessment and related characteristics

Suicidal Ideation Assessment (SBQ-R)

This study found that 20(13.6%) non-suicidal participants and two-third 50(67.6%) suicidal participants had suicide attempt history. Six 6(4.1%) controls and 20(27.0%) cases had suicidal attempt in their lifetime. 22(15.0%) controls 34(45.9%) cases had one time suicidal ideation in the past year; and 4(2.7%) controls 39(52.7%) cases had suicide threat. Two-third, 50(67.6%) suicidal respondents responded that they will have likelihood of suicide in the future (Table 5).

Suicide attempt-related characteristics

This study revealed that 4(2.7%) controls and 11(14.9%) cases had a family history of suicide. Only 2(1.4%) non-suicidal respondents and 24(32.4%) suicidal respondents had current thought about killing oneself); and 20(13.6%) non-suicidal participants and three-fourths, 56(75.7%) suicidal participants had previously suicide attempted history. From 24 suicidal respondents that have current suicidal ideation, 14(58.3%) had the intention to kill themselves via poison, fall from a hill, drown, and availability of lethal methods during that time.

Regarding the intention to attempt suicide, 11(64.7%) respondents who had suicidal ideation that intended to kill themselves via falling from hill, drowning, and burning parts of body and poisoning; and 34(60.7%) suicidal participants were attempted at home. Sixteen (80.0%) controls and 28(50.0%) cases were felt guilty after attempt suicide. Thirteen (65.0%) controls and 29(51.8%) cases aborted suicide attempt by family, whereas 17(85.0%), 16(80.0%), 16(80.0%) controls and 34(60.7%) cases attempted suicide at home (Table 6).

Determinants of suicidal ideation

Sociodemographic determinants

Marital status (being divorced or widowed) is 0.2 times less likely to have suicidal ideation than married (AOR = .20, 95% CI .046–.879). On the other hand, educational status, age, and alcohol were not significantly factors in this study.

Biopsychosocial determinants

This study showed that patients who had family mental illness history are 3.03 times more likely to have suicidal ideation than those had not family mental illness history (AOR = 3.029, 95% CI 1.088–8.431), P = 0.034) and having family suicide history is 6.87 times more likely to have suicidal ideation than participants without history of family suicide (AOR = 6.87, 95% CI 1.138–41.531, P = 0.036). Patients who had previous attempts history are 27.46 times more likely to have suicidal ideation than those patients did not attempt (AOR = 27.457, 95% CI 10.417–72.368, P = 0.0001). On the other hand, physical illness was not a significant factor in this study.

Psychiatric disorder determinants

This study revealed that major depressive disorders are 11.18 times more likely risk to have suicidal ideation than those patients their diagnosis is bipolar disorders (AOR = 11.182, 95% CI 2.382–52.501, P = 0.002). In addition to major depressive disorder, other psychiatric disorders (those who have comorbid diagnosis that is MDD comorbid with PTSD, PTSD, schizophrenia comorbid with PTSD, SAD comorbid with GAD, OCD, GAD comorbid with MDD, schizophrenia comorbid with depression) were 12.25 times more likely risk to have suicidal ideation than patients whose diagnosis is bipolar disorders (AOR = 12.245, 95% CI 1.898–78.986, P = 0.008). On the other hand, psychiatric disorders like schizophrenia, other psychotic disorder were not significant factors in this study (Table 7).

Discussion

This study showed that a family history of suicide attempt was a significant predictor of suicidal ideation. This finding is in line with others studies done in Ethiopia, Addis Ababa and Dessie [10, 17]. Also, in this study, having a family mental illness history is a significant predictor of suicidal ideation. This finding was consistent with studies done in Eastern Nepal and Ethiopia, Jimma [13, 18].

This study also revealed that a previous suicide attempt history was significant for suicidal ideation. This finding was consistent with findings in America; Malaysia; Ethiopia, Addis Ababa and Gonder [4, 16].

This study showed that major depressive disorders were a significant predictor of suicidal ideation. This finding was in line with studies done in America; in America, Washington DC; China; Lithuania; Finland, Helsinki; Japan; Germany, Jena; Eastern Nepal; South Africa; and in Ethiopia, Jimma [4, 6, 8, 9, 11, 12, 14,15,16, 18].

This study also revealed that other psychiatric disorders (those who have a comorbid diagnosis that is MDD comorbid with PTSD, PTSD, schizophrenia comorbid with PTSD, social phobia comorbid with GAD, OCD, GAD comorbid with MDD, schizophrenia comorbid with MDD) were significant factors for suicidal ideation. This finding was consistent with findings in America, Washington DC; Germany, Jena; Ethiopia, Addis Ababa and Jimma [6, 15, 17, 18].

Conclusion

Marital status, family mental illness, family suicide history, previous suicide attempt, major depressive disorders and other psychiatric disorders that are those comorbid were significant factors of suicidal ideation.

Recommendation

  • Psychiatric professionals should assess patient suicidal risk assessment routinely and should put the diagnosis with suicidal if the client is suicidal so that every professional focuses on treatment besides the medication.

  • Educate the family/caregivers of suicidal patients with previous attempts, current suicidal ideation and intention to have closely followed up.

  • It is also recommended researchers to conduct further research studies.

Limitation of the study

Despite providing valuable baseline data, there are also some limitations encountered:

  • Case–control nature of the study design: unmatched case–control does not control confounding factors.

  • In this study, only adult psychiatry patients were included, so it is difficult to generalize all psychiatry patients because those who were unable to communicate, children and adolescents psychiatry patients; and decision incapacity consent were not included in the study. So, those excluded participants might be highly suicidal.
