“…These lower values are probably related to the variability in the raters’ ability to engage subjects and to facilitate the disclosure about history of suicidal ideation and attempts. The reliability measures of the Arabic ISST are similar to those reported for the original English ISST [26] and Polish version [38] in regard to internal consistency and inter-rater reliability. This is the first study to report on test retest reliability with ISST.…”

“…This is the first study to report on test retest reliability with ISST. The results of the PCA (construct validity) produced also three components as the English [26] and Polish ISST [38]. In the Arabic ISST, the first factor involved suicidal thinking in the current state, the second one covered passive suicidal ideation, and the third factor involved suicide contemplation.…”

“…The validation study of the Polish version of the ISST reported that the PCA produced also three factors, which were reported to be congruent with those of the English ISST [26]. However no details are available as only an abstract [38] was published on the Polish version.…”

BackgroundPatients with schizophrenia are known to have higher rates of mortality and morbidity when compared to the general population. Suicidality is a major contributor to increased mortality. The International Suicide Prevention Trial (InterSePT) Scale for Suicidal Thinking (ISST) is a validated tool to assess current suicidal ideation in patients with schizophrenia. The aims of the study were to culturally adapt the Arabic translation of ISST and to examine the psychometric characteristics of the Arabic version of the ISST among patients with schizophrenia in Qatar.MethodsISST was translated and adapted into formal Arabic using the back translation method. Patients diagnosed with schizophrenia were randomly recruited from the department of Psychiatry, Rumailah Hospital, Doha, Qatar. Healthy controls were randomly recruited from two primary health care centers in Doha, Qatar. The Arabic version of Module B for suicidality in Mini International Neuropsychiatric Interview was used as the gold standard to which the Arabic ISST was compared.ResultsThe study sample (n = 199) was composed of 100 patients diagnosed with schizophrenia (age 35.30 ± 10.04 years; M/F is 2/1) and 99 controls (age 33.98 ± 8.33 years; M/F is 2/3). The mean score on the ISST was 3.03 ± 4.75 vs. 0.47 ± 1.44 for the schizophrenia and control groups, respectively. Inter-rater reliability coefficient was 0.95, p > 0.001. The overall Cronbach’s alpha was 0.92. Principal Component Analysis produced 3 factors explaining a total of 73.8% of variance.ConclusionsThis is the first study in the Arab countries to validate the Arabic version of the ISST. The psychometric properties indicate that the Arabic ISST is a valid tool to assess the severity of suicidal ideation in Arabic patients with schizophrenia.
