Objective: The aim of this study was to investigate the dimensions of agitation in dementia patients using the Turkish version of the Cohen-Mansfield Agitation Inventory (CMAI-T). Materials and Method: The study included 100 patients diagnosed as dementia, according to the DSM-IV-TR. The CMAI-T was administered to the patients' caregivers via face-to-face interviews. The Standardized Mini Mental State Examination (SMMSE) was used to assess cognitive functions. The severity of depression and the functional state of the patients were assessed using the Cornell Scale for Depression in Dementia (CSDD) and the Functional Activities Questionnaire (FAQ). Principal component analysis and varimax rotation were used to determine the factor structure of the CMAI-T. Results: Factor analysis of the CMAI-T indicated a 3-factor structure: physically aggressive agitation, verbal agitation, and physically non-aggressive agitation. In 92% of the patients there >= 1 was agitation behavior during the previous 2 weeks. The CMAI-T total and factor scores were negatively correlated with the SMMSE scores, and positively correlated with the CSDD and the FAQ scores. Conclusions: The CMAI-T yielded 3 factors (physically aggressive agitation, verbal agitation, and physically non-aggressive agitation), which indicated the scale had construct validity Agitation behaviors were associated with cognitive dysfunction, symptoms of depression and general level of functioning. Additional research is necessary to identify the predictors of these dimensions in different dementia samples, and to determine the efficacy of therapeutic interventions.

Investigation of the Psychometric Properties of the Turkish Form of Subjective Memory Complaints Questionnaire
(Gunes Kitabevi Ltd Sti, 2013) Ozel Kizil, Erguvan Tugba; Baştuğ, Gülbahar; Duman, Berker; Altintas, Ozge; Kirici, Sevinc; Bastug, Gulbahar; Baran, Zeynel; Altunoz, Umut; 48292; Psikoloji
Introduction: Amnestic type of mild cognitive impairment (MCI) is characterized by the presence of subjective memory complaints and impairment of memory tests. This study aims to investigate the validity and reliability of the Turkish Version of the Subjective Memory Complaints Questionnaire (SMCQ). Materials and Method: The study sample consisted of 45 MCI patients and 44 healthy elderly controls. The SMCQ is a 14-item, "yes-no" questionnaire which evaluates the severity of subjective memory complaints. The discriminant validity of SMCQ was evaluated by comparing the scores of the two groups. For concurrent validity, the correlations between SMCQ and two widely-used cognitive screening tests (MMSE and ADAS-Cog) were calculated. ROC analysis was performed to test the diagnostic validity. For reliability analysis, internal consistency was calculated. Results: SMCQ scores of the patients were higher than the controls. SMCQ scores of the subjects were positively correlated with ADAS-Cog and negatively correlated with MMSE scores. Cronbach's value was 0.83. ROC analysis yielded a sensitivity of 80% and a specificity of 66% (cut-off=4.5). Area under the curve was 0.843. Conclusion: SMCQ is a valid and reliable instrument that can be used for the assessment of SMC in elderly patients. However, community based studies should be carried out for suggesting SMCQ as a screening tool.

Misinterpretations of Intrusions, Obsessive Beliefs and Thought Control Strategies in Patients With Obsessive-Compulsive Disorder
(Cumhuriyet Univ Tip Fak Psikiyatri Anabilim Dali, 2013) Yorulmaz, Orcun; Baştuğ, Gülbahar; Bastug, Gulbahar; Tuzer, Verda; Goka, Erol; 48292; Psikoloji
Objective: Misinterpretations of intrusive experiences are suggested to play critical role in the development and maintenance of obsessive-compulsive disorder (OCD). Some faulty belief domains are also assumed to contribute to the immediate misappraisal of intrusions and thus, patients with OCD try to control their thoughts with various thought control strategies. This study aims to examine these cognitive concepts among Turkish patients with OCD and comparatively review the psychometric characteristics of three instruments in clinical samples. Methods: The sample of the study was constituted of patients with OCD and any other anxiety disorders and undergraduate university students as control group. An instrument set on immediate misinterpretations, beliefs, control strategies, responsibility attitudes, fusions of thoughts and actions, thought suppression, OCD symptoms, self-esteem and personality characteristics was administered to the sample. Results: Having acceptable reliability values, instrument tools of immediate interpretations, beliefs and thought control methods were found to be higher in OCD patients. These three factors were found to be significantly associated with other relevant cognitive correlates, while they were not related to some other factors such as psychoticism. Conclusion: These findings show that misinterpretations of intrusions, beliefs and control methods are also valid concepts in Turkish clinical samples that live in a different cultural context, and the self-report instruments of these cognitive factors were shown to display satisfactory psychometric properties.

Psychometric Properties of the Turkish Version of Cohen- Mansfield Agitation Inventory In Patients With Dementia
(Gunes Kitabevi Ltd Sti, 2012) Ozel-Kizil, E. Tugba; Bastug, Gulbahar; Erdogan, Seyda; Sakarya, Direnc; Durmaz, Nazli
Introduction: Cohen-Mansfield Agitation Inventory (CMAI) is frequently used in patients with dementia for the assessment of agitation severity. This instrument is especially used in research investigating the severity of behavioral symptoms and their treatment responses. In this study, psychometric properties of the Turkish version of CMAI were investigated in patients with dementia (n=52). Materials and Method: CMAI-Turkish version was applied by face-to-face interview to the caregivers of dementia patients who were admitted to a geriatric psychiatry outpatient clinic. For validity, the correlations between CMAI total scores and Neuropsychiatry Inventory (NPI) total and subscale scores were evaluated. For internal consistency, Cronbach alpha value of the items was calculated. Results: CMAI scores were significantly correlated with NPI scores and Cronbach alpha value of the scale was high (0.89). Conclusion: Turkish version of CMAI is a valid and reliable tool for the assessment of the frequency and severity of agitation behavior. Further studies might evaluate inter-rater reliability of the scale in inpatients with dementia.
