Objective: The aim of this study is to determine the psychometric properties of the Turkish version of the SF-12 Health - a widely used scale that assesses health - related quality of life - and to assess whether its psychometric properties are as good as with the 36 items long version (SF-36).

Method: The study included a total of 190 participants including 138 young adults aged from 18 to 29 years (22.04±2.35) and 52 older adults aged from 60 to 80 years (67.27±5.22). The relationships between EQ-5D-3L, CES-D and SF-12 scales were investigated for content, convergent and divergent, criterion-related and the known-groups construct validity. In order to assess reliability, internal consistency and item-total correlation coefficients were calculated and test re-test analyses were conducted.

Results: The internal consistency coefficients of the scale were found to be satisfactory (for the components α=0.73 and 0.72). Consistent with the original study, physical and mental components of the SF-12-TR were found to be strongly correlated with the components of the SF- 36 and explained, respectively, 86.6% and 92.4% of the variance. The components of the SF-12-TR were found to be moderately or strongly correlated to the sub-dimensions of the EQ-5D-3L and CES-D, which measure the same structures, while they were unrelated or weakly correlated with the sub-dimensions measuring different structures.

Conclusion: The findings indicated that the psychometric properties of the Turkish form of SF-12-TR are similar to the original version, and the SF-12-TR can be used as an alternative to the SF-36-TR in clinical and research settings in our country.

Objective: To review and summarize data on the prevalence of overall personality disorder extracted from SCID-II (Structured Clinical Interview for DSM-III Axis II Disorders) studies conducted in Turkey with samples consisting of mental health consumers, and also to elaborate on the level and sources of heterogeneity.

Method: MEDLINE, WOS, PsycINFO, ScienceDirect databases as well as the Turkish Psychiatric Database have been systematically searched. Relevant studies conducted with samples composed of psychiatric inpatients or outpatients receiving psychiatric treatment were included. The diagnostic rate of any personality disorder was regarded as the valid indicator of the overall personality disorder prevalence; therefore, papers presenting data not conducive to this goal were excluded.

Results: A total of 311 papers were identified, and 55 studies were included in the qualitative synthesis. Following a critical appraisal of the quality of the data involving point prevalence rates ranging from 20% to 100%, we decided to include 35 studies in the quantitative synthesis. A random-effects meta-analysis followed by a subgroup analysis yielded a summary estimate of 52% [46 - 58%] for the prevalence of overall personality disorder. A high level of overall heterogeneity 84.8 % [80.0 - 88.4] was found to persist in each diagnostic subgroup with a particular primary diagnosis.

Conclusion: The prevalence estimates derived from the meta-analysis of the SCID-II studies conducted in Turkey support the notion that personality disorder is present in nearly half of the mental health service consumers. That the level of heterogeneity across studies originating from Turkey alone was as high as those observed in previous reviews covering studies originating from various countries suggests that the very source of such heterogeneity might be questionable validity and reliability of SCID-II diagnoses.

Dear Editor, The costs of antipsychotic drugs (APDs) used in the treatment of mental disorders with psychosis are mentioned in treatment guidelines (APA 2021, NICE 2014). While the American Psychiatric Association guideline states that every specialist should make decisions according to the rules and conditions of their country and their region, the National Institute of Health and Clinical Excellence guideline emphasizes that drug costs must be taken into consideration in the treatment process. Classical or first-generation antipsychotic drugs (FAPDs) are relatively cheaper in terms of sales prices compared to atypical or second-generation antipsychotic drugs (SAPDs) with a slightly different effect mechanism. The price difference between the two drug groups can be so large that sometimes it may be necessary to consider whether the cost of a second-generation drug is worth its benefit. While deciding on the use of first-generation or second-generation drugs, a multifaceted assessment should be made, such as the patient's level of compliance with the treatment, the possibility of occurrence of side effects, the possible effects of these side effects on body health and treatment compliance, and whether or not the costs are covered. The most important criterion that determines the choice of medication for psychiatrists is of course the multi-dimensional benefit/harm ratio that the drug used will reveal in the long term. We think that in our country, which, in terms of economic indicators is not in a strong position as an importer of pharmaceutical raw materials from abroad, APDs' cost calculation should be considered because drug costs constitute an important part of the direct treatment costs of psychotic disorders in developing countries such as Turkey (Yıldız and Cerit 2006). We calculated the unit (mg) price based on the box prices of the APDs in use in 2020, thinking that it might work when calculating the cost of the illness using APDs as the main component of the treatment and calculated the annual average drug costs with the daily average dosage. Although the daily treatment dose varies with the stage of the illness and the individual characteristics of the patient, the average doses recommended for maintenance treatment were used here (Öztürk and Ulusahin 2018). The daily and annual cost calculations based on the assumption that the average maintenance treatment dose was used with the unit price obtained from (Drug Prices 2020) the drugs in the Turkish pharmaceutical market in September 2020 are shown in Table 1. A similar study was done in 2005 (Yıldız 2005). The purpose of this article is to redetermine the average costs of APDs in the Turkish pharmaceutical market every 15 years and to bring them to the attention of experts in terms of cost-effectiveness studies. When the costs in 2005 are examined, it is seen that the annual costs of the FAPDs were around 450 TRY, and the annual cost of oral preparations of SAPDs was 2,500 TRY (5

Objective: The aim of this study was to compare the formal thought disorder (FTD) in the acute episode of schizophrenia (SCHZ) and bipolar affective disorder (BPAD), and to determine the FTD dimensions associated with BPAD.

Method: The study included a total of 34 SCHZ patients not meeting the standardized remission criteria and 20 patients in BPAD manic episode. The patients completed the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression Scale (CGI), the Young Mania Rating Scale (YMRS), the Hamilton Depression Rating Scale (HAM-D) and the Thought and Language Disorder Scale (TALD) in order to assess FTD. The association of FTD with the diagnoses was analyzed by a logistic regression model including the TALD factors and the SCHZ and BPAD groups.

Results: Statistically significant differences were not determined between the demographic features, the CGI scores and the TALD objective positive factor scores of the SCHZ and BPAD groups. The objective negative and subjective negative factors (p<0.001 for all) were higher in SCHZ group and the subjective positive factor were significantly higher in BPAD group (p=0.028). In the logistic regression model, the TALD subjective positive factor was associated with BPAD diagnosis, and the objective negative factor was associated with SCHZ diagnosis. In the BPAD group, the TALD total score correlated positively with the manic episode severity, and the scores on the subjective negative and subjective positive factors correlated negatively with disease duration.

Conclusion: The study results show that FTD is common to the acute episodes of both SCHZ and BPAD and that assessment of the subjective positive FTD symptoms and objective negative FTD symptoms may be useful to differentiate the acute episode of SCHZ from the BPAD manic episode.

Objective: In this study, the losses of neurocognitive function caused by the use of cannabis and synthetic cannabinoid were studied on specific cognitive areas (attention and working memory, executive functions, visuospatial perception, learning and memory, planning and problem solving, word naming) and were described in comparision with healthy controls (control group).

Method: In this study, while 52 participants who applied to Ege University Faculty of Medicine Department of Mental Health and Mental Disorders Drug Addiction Treatment Center Clinic between March 2015 - February 2017 and used cannabis at least for one year in the past and 51 participants who used synthetic cannabinoids for at least one year in the past were participant groups with a history of substance use; 57 staff/student of Ege University with no history of any substance use were participants of the control group. The research sample consisted of 160 participants. The sample group consisted of 160 men aged 18-35, and also 16 participants aged 36-54 were involved in the study in order to observe neuropsychological functions that changed with age. Stroop Test for attention area, Raven Standart Progressive Matrices Test for executive functions area, Line Orientation Test and Cancellation Test for visuospatial perception area, Serial Digit Learning Test and Öktem Verbal Memory Progresses Scale for learning and memory area, The Tower of London Test for planning and problem solving skill, Boston Naming Test for word naming area were used.

Results: In this study, while the lowest perfomance on the ability of focused attention, visuospatial cognition, visual scanning, orientation, sustained attention, general ability, short-term memory, learning, long-term memory, word naming was shown by the participants with a history of synthetic cannabis use, the participants with a history of cannabis use had the lowest performance on the ability of response rate, perseveration, conceptualizing, abstract thinking, changing sets, recognition. Participants' history of substance use did not affect the ability of planning and problem solving.

Conclusion: In conclusion, this study suggests that the addition of cognitive rehabilitation programs to medical and psychosocial improvement studies carried out in the field of addiction will increase the success.

Objective: Anhedonia, which is defined as diminished capacity of having pleasure, is a common symptom in many mental disorders. It has been aimed in this study to adapt to the Turkish language the Snaith- Hamilton Pleasure Scale Clinician Administered Form (SHAPS-C) and examining reliability and validity of Snaith-Hamilton Pleasure Scale Clinician Administered Turkish Form (SHAPS-C-TR) which measures anhedonia in clinical and healthy samples.

Method: Two groups consisting of 63 participants consulting the psychiatry clinic and 67 non-clinical participants were included in the study. Data were collected with the Turkish version of the SHAPS-C (the SHAPS-C-TR), the Beck Depression Inventory (BDI), the Montgomery-Asberg Depression Rating Scale (MADRS) and the Positive Negative Affect Scale (PANAS).

Results: The Kuder-Richardson internal consistency coefficient for the entire participants, the clinical and the non-clinical group were, 0.765, 0.813 and 0.657 respectively. The intra-class coefficient for test-retest reliability was 0.732. The total score on the SHAPS-C-TR significantly correlated with the scores on the anhedonia items of the BDI and the MADRS but not the scores on anxiety items. The PANAS positive symptoms scores were negatively correlated with the SHAPSC- TR total score. In the clinical group, the participants followed up with depression had significantly higher SHAPS-C-TR score than the rest of the participants. A similar difference was not demonstrated by the scores of the clinical group participants followed up with anxiety disorder. Scores on the SHAPS-C-TR did not vary with respect to the demographic characteristics of the participants.

Conclusion: The SHAPS-C-TR is a valid and reliable measurement tool to assess anhedonia in both clinical and non-clinical individuals irrespective of differences in demographic features.

Objective: Sleep disorders increase the symptoms of attention deficit hyperactivity disorder (ADHD). The aim of this study was to investigate whether or not sleep related problems give rise to symptoms of attention deficit and hyperactivity-impulsivity in university students.

Methods: The 252 university students between the ages of 18-25 years included in the study were assessed on the Pittsburgh Sleep Quality Index (PSQI), the Adult Attention-Deficit Hyperactivity Disorder Scale, the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI).

Results: The participants of the study comprised 38.5% males and 61.5% females with a mean age of 22.39 (±1.93) years. The mean score data were 5.78 (± 2.72) on the PSQI, 41.77 (± 20.38) on the Adult Attention-Deficit Hyperactivity Disorder Scale, 8.53 (± 6.97) on the BDI and 9.05 (± 7.92) on the BAI. The total score and the scores on the attention-deficit and the general problems subsections of the Adult Attention-Deficit Hyperactivity Disorder Scale were significantly higher in participants with poor sleep quality (P<0.001). The PSQI and the Adult Attention-Deficit Hyperactivity Disorder Scale scores were significantly above the cut-off values in the participants with depression and anxiety symptoms as compared to those without these symptoms (P<0.001). The PSQI total score positively correlated with the Adult Attention-Deficit Hyperactivity Disorder Scale total score (P<0.001).

Conclusion: University students with sleep disorder have more ADHD symptoms and poor quality of sleep increase ADHD sypmtoms. Therefore it's important to evaluate quality of sleep in young people suffering from attention problems in terms of treatment approaches and interventions.

Functional movement disorders (FMD) are abnormal involuntary movements that are not attributable to known neurological and neuroanatomical causes. In the past decade, FMD diagnoses have been based on positive factors that are inconsistent with neurological disorders and not on the exclusion of neurological disorders. In this report, we presented the case of a female patient who had been followed up for 4 years in multiple health centers with the diagnosis of a neurological disorder which was suspected in the previous 1 year to be of psychogenic origin. A neurological disorder comorbid with depression and FMD was diagnosed after admission as an inpatient to our clinic. By presenting this case, it was intended to emphasise the importance of follow up after diagnosing FMD, given its common basis with Parkinson's disease and the high incidence of comorbidites seen with it. Imaging and elecrophysiological techniques should be relied upon.for differentiating FMD and neurological diseases. Although psychological causes are significant disease risk and/or maintenance factors, they are not sufficient for explaining the aetiology of FMD, which requires a multidisciplinary approach. Keywords: Functional movement disorders, Parkinson's disease, DaTscan.

Objective: The Morningness-Eveningness Questionnaire (MEQ) has been widely used to determine chronotype. The Munich Chronotype Questionnaire (MCTQ) was developed as an alternative measurement tool to the MEQ, focusing on different sleep behaviors on work and free days. The aim of this study was to adapt the MCTQ to the Turkish language and to validate the questionnaire on young and healthy adult members of the Turkish population.

Method: This study was conducted with total of 214 (161 Female, 53 Male) healthy young adult volunteers between the ages of 18-30 (M=20.72, SD=2.33) from Hacettepe University. After adaptation to the Turkish language to form the MCTQ-TR, the psychometric properties were compared with the MEQ-TR. The test retest reliability of the MCTQ-TR was investigated on 25 participants (19 Female, 6 Male), 4 months after the first application.

Results: The test-retest reliability coefficient of the MCTQ-TR was calculated as r=0.643 (p<0.05). The validity and reliability results indicated a negative and statistically significant correlation between the MEQ-TR and MCTQ-TR scores (r=-0.627; p<0.001).

Conclusion: The MCTQ-TR is a valid and reliable measurement tool that can be used to determine chronotype in healthy Turkish young adult population.
