“…We used the Calgary Depression Scale for Schizophrenia (CDSS) to differentiate between depression and negative symptoms in schizophrenia patients and the International Suicide Prevention Trial (InterSePT) scale for the evaluation of suicidal ideation. All the scales used were the Arabic versions that were validated for use in Arabspeaking subjects [29,34,35]. Four research assistants were trained to administer these scales similarly to all subjects involved in the study.…”

Background Adequate sleep and physical activity have been linked to the overall well-being of both medical and psychiatric patients. Patients with schizophrenia have shown abnormal sleep patterns and decreased physical activity that were linked to their psychopathology and physical health. These phenomena are not studied yet in Arab patients with schizophrenia. The purpose of this study is to study the sleep and exercise patterns in Arab patients with schizophrenia compared with those of healthy controls. Method A total of 99 patients with schizophrenia and 101 controls were recruited. Arabic versions of sleep, exercise, sociodemographic, and clinical questionnaires were administered as well as the validated scales to measure psychopathology, depression, and suicidality in these participants. Results The majority of patients with schizophrenia slept more than 8 h per day and exercised less when compared with controls. Sleep quality was worse in those with higher depression score and higher suicidality scores were seen in patients with lower sleep duration. Multinomial regression showed that patients with schizophrenia have higher odds of sleeping more than 8 h even after controlling for the intake of antipsychotics, age, gender, smoking status, and other confounding factors. Conclusion Our results showed that Arab patients with schizophrenia are at increased risk of having longer sleep duration with inadequate physical activity, which are correlating with worsening of depressive symptoms and suicidality. Thus, more attention should be paid to the changes in sleep patterns and level of exercise when treating Arab patients with schizophrenia.

“…This cross-sectional study is part of a project aiming to validate the Arabic versions of psychiatric scales used in the assessment of patients with schizophrenia in the Arab population residing in Qatar (Hammoudeh et al 2016;Hani et al 2016;Yehya et al 2016;Yehya et al 2017). This paper reports a secondary analysis of the relationship between the Arabic MINI6-Mod-K and PANSS.…”

The Mini International Neuropsychiatric Interview, version 6, module K (MINI6-Mod-K) is a diagnostic tool to confirm schizophrenia; whereas the Positive and Negative Syndrome Scale in Schizophrenia (PANSS) is a scale to assess psychotic symptoms severity. The objective of this study was to cross-validate the diagnostic questions (categorical) from the Arabic MINI6-Mod-K with the corresponding items' scores (dimensional) from Arabic PANSS. Arab subjects (N = 101) were recruited from the Psychiatry Hospital in Qatar. MINI6-Mod-K was used to confirm schizophrenia diagnosis, and PANSS was administered to assess psychopathology by an independent rater. The most common symptoms according to MINI6-Mod-K were the delusions and hallucinations but the PANSS items scores ≥2.5 captured more positive responses on all the diagnostic features of schizophrenia. The cutoff PANSS scores that significantly distinguished between the presence or absence of schizophrenia features on MINI6-Mod-K were mostly between 2.5 and 3.5. Multivariate linear regression showed that negative symptoms and disorganized/catatonic behaviors independently contributed to the PANSS score on positive symptoms subscale. However, none of the symptom questions in the MINI6-Mod-K were significant predictors of the PANSS negative score. Our results showed that there is very good cross-validation between the diagnostic questions of Arabic MINI6-Mod-K and the corresponding positive cutoff scores in Arabic PANSS.

“…The CDSS is a 9item scale which has been shown to tap into depressive symptoms of people with psychotic illnesses. It has been established to have adequate psychometric properties across various ethnic and linguistic groups around the world [18,19] including the Arabic version that is currently being used [20]. The CDSS is scored as follows: 0-9 = no depression, scores 10-15 = mild depression, scores 16-23 = moderate depression, scores > 24 = serious depression.…”

Psychiatric, cognitive functioning and socio-cultural views of menstrual psychosis in Oman: an idiographic approach

et al. 2020

Background Most documented cases of menstrual psychosis have been from Euro-American populations with reports from cross-cultural populations being only a few. A primary aim was to determine whether the cyclical/episodic nature of menstrual psychosis among case series observed at a tertiary care unit in Oman fulfills the diagnostic criteria of the International Classification of Diseases (ICD-10) and diverge into Brockington’s sub-types (World Psychiatry. 2005;4(1):9–17). Related aims were to solicit measures of psychometric functioning of those with menstrual psychosis and associated idioms of distress. Methods A series of consecutive patients seeking psychiatric consultation from January 2016 to December 2017 were screened via structured interview—Composite-International Diagnostic Interview (CIDI) and Brockington’s sub-types. The identified patients (n = 4) also underwent psychometric evaluation including examination of affective functioning, intellectual capacity and neuropsychological functioning (i.e.attention and concentration, learning and remembering, executive function, processing speed and speech and language). The analysis of outcome measures was via an idiographic approach. Results The spectrum of distress among people with menstrual psychosis does not fit existing psychiatric nosology. Evaluations revealed that a majority of the participants displayed something akin to morbid phenomena relating to manic and psychotic symptoms. In the parlance of traditional Omani society, this would be termed “spirit possession”. In terms of classification by timing within the menstrual cycle as expounded by Brockington, the present case series in Oman fulfilled the definition of catamenial psychosis and paramenstrual psychosis. With regard to psychometric function, all participants performed adequately on indices of intellectual functioning but appeared to have impairments in neuropsychological functioning, including the dimensions of processing speed, episodic memory, and executive functioning. Within the given society, the periodicity of mind alteration has been attributed to spirit possession. Conclusions This is one of the first case series of its kind in the country elucidating whether the manifestation of menstrual psychosis among individuals in Oman fulfills the subtypes postulated by Brockington. The present case series suggests that menstrual psychosis is marked with neuropsychological impairments that were previously observed in other phasic manic episodes or brief psychotic disorders.
